Dear Mr. Stienmetz:
Dee Freeman
Secretary
S abject: Response to comments - Draft NPDES Stormwater
Permit
Permit No. NCS000360
National Institutes of Environmental Health Sciences
Durham County
The Division of Water Quality's (DWQ) Stormwater Permitting Unit (SPU) received a comment letter
regarding Draft Permit NCS000360 on July 6, 2010. After conferring with the Raleigh Regional Office,
the Stormwater Permitting Unit responds to your comments as follows:
Q: "The compliance schedule in Part III, Page 1 of 8 states that existing facilities applying for a
permit renewal shall annually update the stormwater plan. How much time is the NIEHS allotted in
order to update the existing plan, which was revised in June 2010?"
A: As the NIEHS updated the plan in June of 2010, an updated version should be completed for June of 2011.
Q: "The NIEHS would like to have the 27-acre NIEHS Lake incorporated into the receiving stream
name".
A: ' The NIEHS Lake is not a classified water body; therefore we cannot add this name as a receiving stream. The
receiving body must be designated as an Unnamed Tributary (LIT) to Burdens' Creek.
Q: "The NIEHS was granted representative outfall status for the Building 108 outfall. We would Iike
to have the sample location designated as ROS instead of stormwater discharge outfall (SDO) in
Table 1..."
A: In an email from Bill Stienmetz dated April 24, 2009, Mr. Stienmetz stated "We have not been able to locate
the letter from NCDWQ that granted representative outfall status." The responsibility of showing representative
outfall status rests with the permittee. Additionally, ROS may be revoked if the process or discharges change, or if
DWQ otherwise deems appropriate. As the NIEHS was not able to locate a letter stating that they have obtained
it, please fill out and return the enclosed ROS form to the DWQ Raleigh Regional Office, attn: Mack Wiggins.
The form can also be found on our website: http//portal.nedenr.org/web/wq/ws/su/npdessw
The designation as SDO in the Analytical Monitoring Requirements is standard practice in DWQ SPU's permit
issuance and does not prevent permittees with ROS status from using that status. Additionally, using the "SDO"
notation allows DWQ to continue using the current version of the permit if outfall statuses change without a
permit modification includin the public notice process). �' 7�` � r_ - �- `"

Q: The qualitative monitoring requirements have been changed and the stormwater visual evaluation
is now to be performed during a representative storm event in conjunction with analytical
monitoring. Does this mean that the qualitative monitoring must also occur with the first 30 minutes
of discharge? In addition, the NIEHS requests approval to continue performing the qualitative.'
monitoring at the representative outfall location ;only.
A: The intention of this permit Ianguage was that the qualitative monitoring should be done at the sume time as
the analytical. Please monitor the discharge within _the first 30 minutes.
Additionally, it is standard language in all of our general and individual permits that qualitative monitoring be..,
performed at each stormwater discharge outfall (SDO) regardless of representative outfall status. Please continue
to monitor all of your outfalls for qualitative parameter regardless of ROS.
If you should have additional comments, please submit them to the Division of Water Quality
Stormwater Permitting Unit by July 30, 2010.

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000360 .
National Institutes of Environmental Health Sciences

Dear Mr. Stienmetz:
Enclosed with this letter is a copy of the draft stormwater permit for your facility.' Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains. .
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes-
1. AnalyticaI monitoring parameters have been added to this permit.
'2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part II Section B.' The permittee must also document the total precipitation for each event. If no discharge
occurs durii g the sampling period, the permittee must submit a monitoring report indicating "No Flow"
within 30 days of the end of the six-month sampling period. Additionally, samples must be taken a
in. inimum of 60 days apart, as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark
values require the permittee to increase monitoring, increase management actions, increase record
keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered program. If the
sampling results are above a benchmark value, or outside of the benchmark range, for any parameter at
any outfall then the facility shall follow the Tier 1 guidelines which require a facility inspection within
two weeks and implementation of a mitigation plan within two months. If during the term of this permit,
the sampling results are above the benchmark values, or outside of the benchmark range, for any specific
parameter at a specific discharge outfall two times in a row (consecutive), then the facility shall follow the
Tier 2 guidelines which require a repetition of the steps listed for Tier 1 and also immediately institute
monthly monitoring for all parameters at every outfall where a sampling result exceeded the benchmark
value for two consecutive samples.
5. You are required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part Il Section B. Qualitative monitoring is required regardless of
representative outfall status.
�_. 6. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)

8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. Monitoring for TPH has replaced Oil & Grease. This requirement appears in
all Individual Stormwater permits, however it only applies to facilities that do vehicle maintenance. If the
facility begins vehicle maintenance during the permitted timeframe then the requirements shall apply.
Other permit changes:
1. AdditionaI guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is.impaired and if it has a TMDL established. It must also describe potential pollutants
i'll"`:` iiAacli'outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past three years and also must certify that the outfalls have
been inspected to ensure that they do not contain non-stormwater discharges. Additional information is
provided in Part II Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A.
More details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention PIan have been specified in Part II
Section A. The plan must also be updated annually to include a list of significant spills and to certify that
the outfalls do not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial
materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the
facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit
requirements. Additional information is provided in Part I Section A.
6. This site discharges to the Jordan Lake Watershed which is experiencing problems with nutrients
(Nitrogen and Phosphorus). A TMDL was approved for the B. Everett Jordan Reservoir in 2007 for a
development strategy to control nutrients and meet the state chlorophyll a standard. The Division will
consider the monitoring results in determining whether additional BMPs are needed to control the '
poIIutant(s) of concern to the maximum extent practicable. If additional BMPs are needed to achieve the
required level of control, the permittee will be required to (1) develop a strategy, for implementing .
appropriate BMPs, and (2) submit a timetable for incorporation of those BMPs into the permitted
Stormwater Pollution Prevention Plan.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] or
[e-mail]

Central Office Review Summary:
1. Owner's Other Permits:
• No non -discharge permits.
• No other permits in B1MS
2. General Observations:
o RRO site visit: lots of 55 gal drums, 3 oil/water separators, above ground fuel oil storage tank -
containment areas, loading/unloading of haz waste area the site was 'ineligible for no exposure, RRO
recommended to reissue permit and not issue No Exposure
o Other: Aluminum exceedences in past monitoring, 2000 gal cap E85 tank, 4000 gal fuel oii tank, 1250
gal emergency generator day tank. Dispense fuel for NIEHS fleet vehicles. Tanks are double walled.
o Haz waste: NIFHS operates Chem. waste TSD facility in bldg 108. Dock has trench drain for
containment of spills. Before 2006 trench drain was open all the time. Atler 2006 trench drain was
replaced to make easier and to be able to maintain and keep closed at all times. Trench drain is visually
inspected before being released.
1, Haz Waste TSD closed down in Bldg 106?
3, Invainnent: 303(d), Basinwide Plan recommendations...
o NIEHS outfall discharges to the -NIEHS Lake" then to Burdens Creek (16-41-1-17-1(0,7)), Burdens'
Creek is not listed on 303D list or have TMDL. However, Burdens' Creek discharges to Northeast
Creek (16-41-1-17-(0.7)a WS-FV water body (in 03-06-05) in approx 0.65 miles from where N1EI-1S
discharge enters into Burdens' Creek, Northeast Creek at this segment has a TMDL for Fecal Coliform,
It also is on the 2010 303D list and is impaired for Aquatic Life (due to Copper, 'Turbidity, and Low
DO).
o Jordan lake 'I'MDL: Chlorophyll a
o In Jordan Lake Watershed — TMDL for TN and TP.
4. Threatened and Endangered:
No Endangered aquatic animal species were found near the NIEHS Site. Only plant species were , However,
Carele"?)title ClolwlLvFvli 131-lt1011 J',1CLdtMi%'C or obligate wetlati t plant.
5. Location:
o Location isjust upstream of WS-1V, not clear if it is draining to C or WS-iV.
o Drains to NIEIIS Lake — which is not on NC water bodies list
o Has TMDLS
o There are 2 locations of the facility — appears to have more locations
6, Industrial Changes -Since Previous Permit:
o Haz Waste TSD closed down in Bldg 106?
o Reduce flow of SW into NIEHS lake by addition of rip -rap.
o Installation of a 2000 gal capacity E85 Storage tank, a 4000 gal fuel oil Storage tank, and a 1250 gal
emergency generator day tank. E85 provides alternative fuel fir NIEHS fleet ol'vchicics. E85 is doublC-
walled and includes overfill alarm. Oil storage tank and generator day tank are double walled. Piping us
double walled as well.
o Bldg 108 has treltch drain for containment spills. Parking lot is graded to draw water away from.
structure and minimize volume of SW. Trench drain has a new lock on valve and remains closes which
is a new practice. Rainwater is visually inspected before releasing.

NCS000360
7. Analytical_NIonitoring, Notes:
o There have been a number of exceedences in Aluminum, and one in C()D. Monitoring was only°
r•cquircd ill the IIrSt and Iast year of the perinil — quarterly. This will change in the new permit to scnli-
allnuallV.
o When 624 and 625 were tested — outfall 2 exceeded Hunian Health I -or PAHs and Freshwater Standards
for Fluoranthene. 624 and 625 need to be continued.
o COD will be kept in the permit. BOD will also be added as Chlorophyll a is part of the 'FMDL for
Jordan Lake.
o Jordan Lake Rules and Jordan Lake TMDL, require monitoring of TN and TP to identify existing
pollutant sources in these watersheds. These will be added to the permit. See attached information
on Jordan Lake Rule Summary and Jordan Lake Rules for more information in background.
o This site may be a good candidate for monitoring acute toxicity of sw — especially coming; from roof
drains where incinerators are exiting above those roofs. However. we are not ready to incorporate acute
toxicity monitoring into this permit as of yet, and I think that we should see how it works at other
facilities and perhaps implement in the next monitoring scheme.
o R110 needs to re-evaluate representative status.
8, Qualitative Monitoring Notes:
o 8 Petroleum spills since 1978,
9. Other:
o ROS was granted for outfalls — see Q/A section of this document below. PRO has been to the site
recently and initiated. recommended and Was the entity to grant ROS. See Answers below in the Q/A
section of the document for more details. Central Office does not want to second-guess the RRO, but
would, like to recommend that the outfall from the pond also be monitored. Please call the central
office regarding the placement of monitoring [also sent message to KROj,
o Burden's creek was changed ti•oni class C to WS-IV

during the sampling period, the permittee must submit a monitoring report indicating "No blow" within 30 days
of the end of the six-month sampling period. Additionally, samples must tie taken a minimum of 60 days apart,
as specified in Table 2.
5. Berichntarks for analytical monitoring have been added to this draft permit. E;xcccdanccs of benchmark values
require the permittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier I and also immediately institute monthly monitoring fir all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
6. The pennittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
outfall status.
7. The permittee is responsible for all monitoring until the renewal permit is issued. Sec: Footnote 1 offables 1, 4,
and 5.
8. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however,)
9. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
I . Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated snore explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
m ensure that they do not contain non-storwater discharges. Additional information is provided in Part 11 Section
A.
2. Additional requirements for the Stormwater Management Pian have been specified in Part If Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stonnwater Pollution Prevention Plan have been specified in Part it Section A,
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharues.
1. The facility must now implement a semi-annual !Facility Inspection Program of the site's stormwater
management controls as specified in Part Ii Section A.
information regarding the No Exposure Exclusion has been added to this draft permit. If industrial ttiaterials and
activities arc not exposed to precipitation or runofl'as described in 40 CFR ti I22.26(g), the Eitcility may qualify
for a NoExposure Exchision from NPI)ES stormwater discharge permit requirements. Additional information
is provided in Part I Section A,

municipal waste.. They have a chcinical waste pickup — and all chemical waste goes to a system — they take out
to a dock area and it goes to building 108 — there determined if they can store or burn or sent offsite. What
kinds of things would they burn? Media, buffers (from running gels). Etc.
Liquids froin research goes to either pathological or municipal solid waste. Any not chemical is municipal solid
waste and goes to the uhcinerator.

5. Q : Please describe otutfall paths and discharges to these areas:
a. Roofdrain discharge: directly to storm drains into underground to NIFHS lake
b. 1-laz waste areas: To trench drain.
c. Oil water separator: piped to N1EHS lake
d. Retenti0n Pond: There is the large lake and a retention pond. It was to slow down water that came form the
root -drains to 105 and 106. Some of the roof drains go to that pond and the drainage ditch.
e. What is the Intennittant stream from retention pond? Water is trickling out of the pond goes into the lake.
That is looked at twice a year during the semi-annual inspections.
6. Q : Please describe how many outfalls you have an outfalls in derail and monitoring:
a. ANSWER: see below - have one outfall. Have ROS.
i. Q: Please describe discharge from haz waste areas, what is stored there, and what outfall this goes to:
a. ANSWER: Loading dock is covered with a roof and the trench train . The trench drain has a drain valve.
Not locked but kept closed. This was started recently. Previously it was left open. Rainwater can enter.
Part of the peak it can rain on it and go back to the trench drain. If they have a spill that is noted in an SOP
and it is noted on a form. They have not had a spill other places on campus -and have been all petroleum
products.
K Q: Please describe discharge from oil/water separators and what outfall this goes to:
a. ANSWER: There is discharge from that. There are 3: those gig that discharges to a grassy area. The
discharge goes into a wooded area into a drainage ditch. About a thousand feet. The others are at 101 C: and
101 F, and that goes directly to an underground stonmwatcr piping to a lake. The valves are kept closed and
locked and they look at it for oil and sheen and that is before it enters the lake. Only from those 3
containments. Those 3 are not double walled -- and those are the 3 or 4 largest tanks for fuel oil - one is for
emergency generators and one for boiler fuel oil.
R. Q: l don't have any monitoring between 2001 and 2005. Why'?
a. ANSWER: They switched over to a 4"' year monitoring of the permit.
10. What is the research being done in bldgs?
a. Environmental health research - mostly using mice. The chemicals for research come into building 101.
There are probably about 10,000 chemicals but very small amounts - a gal is a very large amount. The
drains for the dock of 101 are traditional storm drams.
1 1. Do you have a procedure in place for a spill
a. They have a RCRA pennit and procedure. Have a sppp for petroleum. The responders are all trained and
have drills,
12. Have you had a spill over there in loading and unloading?
a. No. Only petroleum spills. Those mostly during fuel oil delivery.
1 3. Are there Roof vents from research bldgs?
a. Ycs - from hoods. Most of those are nat controlled. Several hoods can combine together and can vent out.
Some have carbon but most do not. Roof drains and the headwall is directly onto the lake. None of the
buiiding have a guttering system - they all have a spout directly into the lake, Piped underground,

Summary of the Jordan Nutrient Rules
August 14, 2009
Strategy Synopsis aird Status
The proposed B. Everett Jordan Reservoir Water Supply Nutrient Strategy is a
comprehensive set of rules designed to address excess nutrients in Jordan Lake that can lead
to algae blooms and other water quality problems. Jordan Lake is an impoundment in the
central Piedmont that drains a mixture of agriculnual and urbanized lands t'ortning the upper
Cape Fear River Basin, including the west side of the Triangle and much of the 'Triad region.
The lake serves as a water supply for the Town of Cary and also has significant recreational
use. The rules are similar to those already in place in the NCUSe and Tar-Pammlico River
Basins. The rules would require all major sources of nutrients to reduce then' loading to the
three arms of Jordan Lake to meet specific percent reduction goals, established through
modeling, that are needed to restore water quality standards and full uses of the lake.
Nutrient sources addressed by the rules include agriculture, fertilizer application, wastewater
discharges, and stonnwater runoff from both new development and existing developed lands.
Local governments would be required to reduce the discharge of nutrients front wastewater
treatment plants and implement programs to address nutrient pollution from both existing and
new development. The nutrient [management strategies implemented to the Neuse and Tar
Pamlico river basins do not address pollUtlOn C0111ing from existing development. A strategy
for existing development was needed in the Jordan Lake watershed because of the significant
nutt•ient contributions from developed lands in this watershed. Also new is a separate tradilig
title that would allow use of the most cost-effective management options to meet the goals.
The set of thirteen Jordan nutrient rules was approved by the Environmental Management
Commission in May 2008, followed by approval of the Rules Review Commission over five
meetings from June through November 2008. The rules were then reviewed by the 2009
session of the General Assembly, having all received the requisite number of objections
during the RRC process. Five of the rules were either replaced or revised by legislation, and
the remaining titles were approved by the General Assembly unchanged. Prior to the EMC
undertaking rule -making, a modeling process was initiated by the Haw watershed dischargers
in 1998, and was followed by an extensive stakeholder input process begun in 2003 and
carried through the formal public comment period in summer 2007.
Lake Hhvtory: The potential for excess nutrients was recognized when B. Everett Jordan Reservoir
Nvas proposed in 1945. The reservoir was approved by Congress in 1963. After years of constructioim
delay dire to projected water quality concerns, the lake was impounded in 1983. It was designated a
Nutrient Sensitive Water that same year by the Envirornnental Management Commission. The lake
has consistently tested as eutrophic or hyper-eutrophic since impounded, indicating high to excessive
levels of nutrients in the water. Nutrients make their way to the lake from sources such as
wastewater discharges, rainfall runo from agriculture, and stornmwater runoff from new and existing
developed lands. Excessive nutrient inputs drive excessive growth of microscopic: algae. which
imparts a greenish, murky appearance to the water. causes taste and odor problems in finished water.
and robs the water of oxygen. stressing or killing fish and other aquatic life. Excess nutrients also
favor the growth of undesirable algae that does not support the food chain and can release toxins into
the water, While not necessarily making the lake unfit for fishing, swimming. or drinking uses.
excess nutrients are impacting these uses. and undesirable algae are present in the lake. Whilc only

one fish kill has been reported to date, taste and odor problems prompted Cary to add chemical
treatment to its drinking water process, and unsightly, smelly water deters swimmers, boaters, and
other sportsmen.
In 2001 the Division of Water Quality determined that the Upper New I -lope Creek Ann no longer
inet its designated uses due to exceedences of the chlorophyll a standard, which measures algal
growth, and in 2006 made the same determination for the rest of the lake. Tile Haw River arm was
also impaired in 2006 for pH exceedences. Both parameters are indicative of excessive nutrients.
These impairments place the reservoir on North Carolina's list of impaired waters under Section
303(d) of the federal Clean Water Act.
Regulatoj ty Mandates: The Clean Water Responsibility Act of 1997, Session Law 1997-458,
required the EMC to set concentration limits oil wastewater facilities discharging, to Nutrient
Sensitive Waters. The next year. Session Law 1998-212 allowed the F..MC to grant a compliance
extension if a facility chose to develop a calibrated nutrient response model for tine water body and
adhere to the results. The Clean Water Responsibility Act also required the EMC to set restoration
goals for nutrient -impaired waters, require steady progress toward those goals and impose nutrient
reduction measures in a fair, reasonable, and proportionate manner on point source and nonpoinnt
sources relative to their contributions. hn 2005, the General Assembly also enacted SL 2005-190 that
directed the EMC to adopt rules to establish and implement nutrient strategies to protect drinking
water supply reservoirs. Jn addition to state requirements, the determination that the reservoir has
impaired water quality triggers federal Clean Water Act requirements to set and enforce nutrient load
reduction limits, known as a total maximum daily load (TMDL).
Rulemaking Process a►rd Public Commews: To comply with the Clean Water Responsibility Act,
wastewater dischargers in the Haw River watershed developed a reservoir model in the late 1990's to
estimate the lake's nutrient reduction needs. The FMC approved the reservoir model in 2002. During
2003-2004 Division staff conducted a 1-'/z year, 22-meeting stakeholder process to apply the
reservoir model and seek. a consensus on lake nutrient loading goals, discharger allocation methods,
and a conceptual nonpoint source strategy'. In 2005. staff solicited public comment on a rules
framework and brought draft rules before the EIVIC's Water Quality Committee. in January 2006,
the committee directed staff to conduct additional stakeholder meetings, which continued thru 2006.
A TMDL for the entire reservoir was approved by the EPA in August 2007'.
Pursuant to the EMC's authorization of draft rules in March 2007 and subsequent notice in the North
Carolina Register, the Division held three public hearings and provided a 90-day written comment
period from June 15 through September 15. 2007 on the proposed rules. Approximately 400 people
attended the hearings, 150 of whom spoke, Staff received more than 7,000 documents, postcards, and
emails providing written comment'. A detailed, 80-page commenter -indexed stmnmary of all public
comments along with staff replies is provided as Appendix D of the Report of Proceedings'.
There were strong objections to the rule fi-orn various parties, especially from local governments and
development interests, particularly concerning the need and effectiveness of the proposed rules.
There were unresolved issues with the model and the data used. Many also felt that the Flaw
communities would pay for the benefit of New Hope convntlnities who withdraw water from the
' Report or other supporting dOCIiiilent(s1 available on DWQ's Jordan nutrient strategy website. at
hiip: h2o crlF ,tut ,nC.i3.; �rti> Jnrc!,n\�nr€tinrSir;rfrt+.- hill)

flake. The most contentious parts of the strategy were the potentially precedent -setting Existing
Development Rule, and the wastewater nitrogen compliance date,
At the same time, thcre was support for the rUICS from environmental groups and lake users.
Supporters cited a longstanding need for restoring the lake, federal and state mandates, eroding
quality of their take use experience, the general importance of the lake, and the collateral benefits to
numerous degraded streams in the watershed.
Nutrient Managentent Strategy Design: The strategy is designed around nitrogen and phosphorus
percentage reduction goals for each of the three arms of.lordan Reservoir because each arm of the
lake responds independently to nutrient inputs received from its watershed. For example, goals for
the Haw Ann of Jordan Lake and corresponding reduction requirements for flaw watershed sources
are driven by existing nutrient inputs from those sources. State law requires fair, reasonable and
proportionate requirements, so each category of sources in a given watershed faces the same
percentage reduction requirements relative to its baseline inputs. The rules are designed to give all'of
the regulated entities maximum flexibility in meeting the reduction goals. One key addition to
maximize options is a new, separate trading rule that provides load -reducing options across regulated
sources. Nutrient sources addressed by the rules include agriculture, fertilizer application,
wastewater discharges, and stormwater runoff from both new development and existing developed
lands. Local governments would implement the wastewater and development rules, including
requirements to protect existing riparian buffers. The existing development component, not included
in previous strategies, is necessitated by the significant nutrient contributions from developed lands
in this watershed. The strategy also recognizes the importance of adaptive management, and
provides for periodic review of the lake's recovery progress to inform potential management
revisions.

PT
• o
Rules Content: All rules full under T 15A NCAC 2B. The following is a brief summary of each of
the thirteen rules:
u Rule . 0262, Purpose and Scope
Describes strategy purpose, scope, and objectives; identifies the set of rules comprising the strategy;
designates Jordan watershed as a 'critical water supply watershed', which allows the EMC to require
more stringent measures than minintturt Water Supply Watershed requirements: defines geographically
the three subwatersheds draining to Jordan Reservoir; identifies the baseline time period; establishes
nitrogen and phosphorus (N and P) percentage reduction goals and corresponding point and nonpoint
source fake loading targets for each arm relative to the baseline; establishes that all local gover l-Anents —
eight counties and 26 municipalities— are subject to certain rules; and provides for adaptive management
following a period of implementation. Each subsequent Rule references parameters set forth in this Rule.
:a Rule .0263, Definitions
Defines terms that apply across rules and are specific to the set of Jordan rules.
zi Rule 0264, Agriculture
Establishes collective nitrogen and phosphorus reduction goals for agricultural operations in the
watershed. The goals include numeric tlu•esholds for livestock operations. Tlu•ee years after effective
date. the Watershed Oversight Committee (formed by the Director) will determine the extent to which the
nitrogen goal has been achieved relative to the baseline period. If the goal has not been achieved, Local
Advisory Committees (LACs) must be formed to develop a strategy to meet the goal. Six years after
effective date, the EMC will determine whether LACs have achieved subwatershed Nand P goals based
on collective implementation. If not, the EMC will require additional BMP implementation as deemed
necessary to achieve the goals within nine years after effective date. The Rule allows trading of
reductions that exceed collective compliance goals. Aiuival reports are required.
❑ Rule .0265 & SL 2009-484, Storrnwater Management for New Development {
Requires all local governments in the Jordan watershed — eight counties and 26 municipalities — to
implement stormwater programs for new development activities. Those programs must be designed to
meet nutrient loading rate targets. Developers will be required to control nutrient export to certain levels
onsite, but can meet remaining reduction needs through offsite measures including payment of fees for
nutrient offset projects or tlu•ough purchase of reduction credits from private sellers pursuant to the Jordan
trading rule .0273. Within eighteen months after effective date, the Division submits a model local
program to the EMC for approval. Within another six months, local governments submit programs for
Division review and EMC approval. Within three years after effective date. local governments implement
permitting requirements. Annual reports are required. This rule will be rewritten to incorporate the
changes of SL 2009-484.
D Session Law 2009-216
The original Existing Development Rule (.0266) that was sent to the General Assembly was disapproved.
However, the rule was replaced and approved by Session Law 2009-216, with an effective date of June
31, 2009. The Session Law retains the basic requirement that nutrient reductions are to be obtained from
local goverrunent's existing development. The bill requires all local governments in the watershed to
develop a Stage 1 adaptive management program by December 31, 2009. This program will contain
similar measures of the Phase 11 storntwater program, and also requires the identification of opportunities
for retrofits and other nutrient redaction projects from existing development. The Division is required to
develop a Model Stage 2 adaptive management program no later than July 1, 2013. The rule also calls for

,in ongoing monitoring program, and DWQ is tasked with providing monitoring reports to the
Commission every three years beginning in March 2014. if water quality standards are not inet to the
U-N'H aria by the March 2014 report, or in the UNH and Haw arms by the March 2017 report. or any
subsequent reports, the Division will notify local governments within the impaired arm of their need to
develop a local Stage 2 adaptive management program. Within six month of notification, local
governments will submit their stage 2 programs to the Division. Within another six months, the Division
will review the programs. The stage 2 programs will essentially contain the same requirements as the
original title: local governments will be required to reduce nutrient loading from existing development to
rtuct the subwatershed goals. A difference from the original existing development rule is that an 8°%
nitrogen and 5% phosphorus reduction will be required froth all three subwatersheds. However, if the
UNH does not achieve water duality standards by March 2023, the local goverrunents in that
subwatershed will be required to revise their program to achieve a 35% reduction in nitrogen. Annual
reports will be required. The Session Law also calls for the Director to form a Scientific Advisory Board
by July 2010. This board will be tasked with identifying management strategies, evaluating the
feasibility, costs, and benefits of the strategies, developing an accounting system, and identifying the need
for improvement or refinements to modeling and other analytical tools used to evaluate water quality.
The Existing Development Rule will be rewritten to be substantively identical to the Sections in Session
Law 2009-216 that cover existing development.
:j Rule .0267, . 0268, .0269 & S.L. 1009-484 Protection of and Mitigation for F_ vistfng Riparian
Buffers
Requires local govertuncnts to implement programs to protect existing vegetated riparian areas within 50
feet of and adjacent to intermittent and perennial streams, lakes, and ponds in the .lordan watershed, The
first 30 feet adjacent to waters is. largely undisturbed forest, while the outer 20 feet may be managed
vegetation. Existing, ongoing activities within buffers may continue as long as these activities or uses
meet the requirements ofthe rule, while a change in land use invokes the protections. These buffer
requirements replace those under the cuirent Water Supply Watershed rules, and provide local
governments the option to require more stringent measures. Certain activities within the buffer are
identified as exempt, allowable, or allowable with mitigation, while uses not listed are prohibited. The
rules provide mitigation options (buffer restoration, land conservation, or mitigation fee payment) where
no practical alternatives exist, as well as variance provisions. The Division of Water Quality implements
the rule for activities conducted: by local governments; state or federal entities; agriculture; forestry; and
in areas where no local buffer program currently exists. Rule .0267 will be rewritten to incorporate the
changes of SL 2009-484.
Rule. 0270 & S.L. 2009-216, Wastewater Discharge Requirements
Distributes the total point source annual N and P mass loading goals for each arm of the lake in the form
of annual mass allocations to existing wastewater dischargers within each of the three subwatersheds.
Discharge concentration equivalents at full Mow range frorn 3.04 ing/L TN and 0.23 mg/L TP in the
Upper New Hope Arm to 5.30 mg/L TN and 0.67 mg/L TP in the Haw River Arm. As in the Neuse River
Basin nutrient strategy. there are provisions for new and expanding discharges; an option for group
compliance; and potential for in -lice fcc payments to offset excecdcncc of the annual loading cap. There
is also an option for transfer of allocation among individual dischargers. Phosphorus compliance date is
the first full year after effective date, while the nitrogen compliance date was revised from 2014 to 2016
by Session Law 2009-484. This rule will be rewritten to incorporate the changes of SL 2009-216.
Rrrle .0271 & S.L. 2009-484, Stor►nwater Requirements firr State and Federal Entities
Fstablishes stortnwater recluireinents for state land federal entities that arc similar those imposed on local
governments for both new tend existing development under rules .0265 and Session Laws 2009-2 16, The

NC DOT is treated differently than other state/federal entities based on the unique character of its
activities. Annual reports would be required. New DOI' road projects would be deemed compliant if
they meet buffer protection rule treatment criteria. Existing development for state and federal entities will
parallel Session Law 2009-216 above, except there will be no stage I program, and entities in the LNH
will only be required to maintain no increases in nitrogen and phosphorus loads from existing
development if adaptive management programs are triggered. DOT is also given the option of
implementing a combination of three stormwater retrofits per year for existing roadway development and
other load -reducing measures identified in the program to control loading from existing development
pursuant to .0271. This rule will be re«•rittcn to incorporate the changes of SL 2009-484.
D Rule .0272, Fertilizer Management
Beginning three years after effective date, the application of fertilizer to lands in the watershed is to be
done either by applicators who have completed nutrient management training offered by the Cooperative
Extension Service, or pursuant to a certified nutrient management plan developed for the lands to which
fertilizer is applied. Also requires property owners to ensure that applicators to their lands have met one
of these requirements. The rule does not apply to fertilization of residential lands done by the
homeowner. Wastewater residuals and septage application have earlier compliance timeframes. Animal
waste application in compliance with a permitted waste utilization plan is deemed compliant.
:I Rule .0273, Options for Offsetting iVutrienr Loads
Provides parties subject to the various rules - new development, existing development, State and Federal
stormwater entities, agriCulture, and point sources — the option to obtain more cost-effective reductions by
purchasing reduction credit from other, offsite reduction sources or private sellers. This open, market -
based framework provides options in addition to the NC EEP option currently used in the Neuse and Tar -
Pamlico strategies. It requires that minimum onsite standards be met before seeking credit elsewhere. It
sets criteria for those seeking to sell excess reductions, and would require Division approval. .
❑ Rule .0311, Cape Fear River Basin (Schedule of Classifications)
Fortnalizes reclassification of the non -Water Supply Watershed portions of the Jordan watershed to WS-

Dear Mr. Wiggins:
The high volume drainage of city water from the NMHS 92 cooling tower to the sanitary sewer caused
floor drains to backup and overflow in a nearby campus building. The excess discharge that caused the
drains to overflow was due to equipment problems and a leak that both occurred during testing of recently
constructed cooling tower piping. The water used during the pipe testing and discharged during the event
was city water that had not been treated with biocides or other chemicals.
The sanitary sewer system did not overflow.from a manhole. Instead, floor drains overflowed in the
NIEHS Building 104 Warehouse, discharged out of the building, and entered a storm drain located at the
end of Warehouse Alley. An estimated 250 gallons of city water from the cooling towers was discharged
through the storm drain and into an unnamed tributary of the NIEHS Lake. The incident occurred
between 11:30 AM and-1:20 PM on Thursday, January 13, 2011.
The overflow discharge was clear during this incident which indicates that the primacy source was city
water from the cooling towers. No discoloration or sheen was observed on the NIEHS Lake or the
affected tributary. Officials at the North Carolina Division of Water Quality and the Durham County
Triangle Wastewater Treatment Plant were notified within five hours after the incident started thereby
meeting the Division of Water Quality initial notification requirements.
The incident ended after the #2 cooling tower water level dropped enough to stop overflowing into the
sanitary sewer. This was an unusual and isolated event. However, a meeting has been scheduled with
upper management to review the event and determine whether there are any action items or preventative
measures needed to avoid future incidents of this nature. A. Sanitary Sewer Overflow Reporting Form is
attached as per your request. Please let me know if you require any additional information concerning
this incident_
Sincerely
I '

rnanufactw ing or litelitlg operations. In ;areas ��here elimination of exposure is not
practical, the stormwater rnanaernent.pian.:sli'a1l �laeunrent the feasibility of
diverting the stormwater runoff away fronn; greats ofpotential contamination.
(b) Second�uy Containment IZegtnin•eMeuts::�ild Recoaryrds. Secondcontainment is
required for. bulb storage of liqu� to tttt�ttal '; stmage in any amount of Section
313 of Title III of the Super fund Amendiiients and Reauthorization Act (SARA)

Pennil No. NCS000360
on -site at all times during facility operations that have the potential to contaminate
stormwater runoff through spills or exposure of materials associated with the.facility
operations. The SPRP must be site stormwvater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) may be.a*component of the SPRP,
but may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. ' Preventative Maintenance and Good Housekeeping Protrram. A preventative maintenance
and good housekeeping program shall be developed. The program shall list all stormwater
control systems, stortmvater discharge outfalls, all on -site and adjacent surface waters and

Pcru►it No. NCS000360
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The'required
monitot'in�tr will reSLLlt in a nnnitnum of ten analytical samplings being Conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater tha.ri 0.1 inches of rainfall. The time
between this storm event and the previous Storrs] event measuring greater than 0.1 inches must be at least
72 hours. ksingle storm event may have a period of no precipitation of up to 10 hours. For example, if it
rains but stops before producing any collectable discharge, a sample may be collected if the next rain
roducin = a discharge begins within 10 hours.

Website: www.niahs.nih.gov
The NIEHS was previously granted Representative Outfall Status (ROS) during the late 1990's for the
stormwater discharge outfall located at Building 108. The NIEHS has referenced the ROS in official
correspondence since that time. However, the original letter from the NCDENR that granted ROS could
not be located for submittal with the stormwater permit renewal application. Therefore the Division of
Water Quality has requested submittal of a new ROS application.
The ROS application and supporting materials, including maps of the current stormwater discharge
outfails, are attached. The NIEHS is requesting ROS for the Building 108 stormwater discharge outfall.
All stormwater discharge outfails located on the NIEHS Campus serve drainage areas with similar
environmental aspects including employee parking lots and delivery vehicle traffic. The Building 108
outfall is best suited for stormwater analytical monitoring as the associated drainage area features include
employee parking lots�and delivery vehicle traffic along with petroleum deliveries, chemical deliveries,
an incinerator plant, and waste handling facility operations. Also, an individual stormwater permit is
required for the waste handling facility as this operation is listed among the 40 CFR Part 122.26 industrial
activities subject to permitting.
Analytical results for samples collected at the Building 108 outfall are attached. Analytical monitoring
has not been conducted at the North Lot, South Lot, F-Module, or Building 104 outfalls. The NIEHS
requests approval to limit qualitative monitoring to these locations and the Building 108 outfall. This
would reduce the burden of evaluating discharge from natural and lightly developed areas.
Please let me know the outcome of this request at your earliest convenience. Submittal of the ROS
request was delayed to allow adequate time for facility mapping. The NIEHS only has until February 28,
2011 to collect stormwater samples during the first sampling period. I can be reached at 919-541-4234 if
you have any questions concerning the attached information.

if a facility is required to sample multiple discharge locations with very similar stormwater discharges, the
permittee may petition the Director for Representative Outfall Status (ROS). DWQ may grant Representative
Outfall Status if stormwater discharges from a single outfall are representative of discharges from multiple
outfalls. Approved ROS will reduce the number of outfalls where analytical sampling requirements apply.
if Representative Outfall Status is granted, ALt out are still subject to the qualitative monitoring
requirements of the facility's permit —unless otherwise allowed by the permit (such as NCGO20000) and DWQ
approval. The approval letter from DWQ must be kept on site with the facility's Storm water Pollution
Prevention Plan. The facility must notify DWQ in writing if any changes affect representative status.
For questions, please contact the DWQ Regional Office for your area (see page 3).

An unauthorized non-stormwater discharge occurred on the NIEHS Campus when a potable water line
unexpectedly separated on June 22, 2011 at about 12:50 AM. The incident occurred in Valve Pit 91,
which is located just west of Building 105 near the north end of Power Alley or about 350 feet from an
unnamed tributary of Burdens Creek.
The water supply to the separated pipe was shutdown as soon as the source of the leak was determined
and the appropriate isolation valve was located. However, water had to be was pumped from the flooded
valve pit in order to allow access for repairs. About 200,000 gallons of potable water was estimated to
have been pumped or discharged from the valve pit during the 21-hour event with about 50,000 gallons
entering an unnamed tributary to Burdens Creek. A fish kill did not occur during this event based on
surface water and shoreline inspections conducted on June 22, 2011 and June 24, 2011.
Officials at the North Carolina Division of Water Quality were notified by telephone within ten hours
after the incident started thereby meeting the initial 24-hour notification requirements. This was an
isolated event caused by unexpected equipment failure. A written reporting form is attached as per your
previous guidance. Please let me know if you require any additional information concerning this incident.

Dear Mr. Wiggins:
The NIEHS Annual Summary Data Monitoring Report (DMR) is attached for calendar year 2010.
Monitoring was not performed at the three stormwater outfalls with analytical monitoring requirements.
This is because our monitoring requirements recently changed and the initial six month sampling period
mandated by our individual stormwater permit continues through February 2011. The NIEHS plans to
collect samples during the next representative storm event. Please contact me at 919-541-4234 if you
have any questions regarding the enclosed report.

NOTE: Contract personnel inspect all fuel oil storage tank containments on a weekly basis. This inspection
includes a visual examination of stormwater for the presence of oil sheen prior to draining the containment basins.
Stormwater releases from the containment basins are recorded in a logbook.
Outfalls
Representative Outfall (Building 108)
' No non-stormwater discharges
Receives stormwater from Building 108 trench drain, Building 108 parking lot stormwater drain,
and some runoff from Buildings 105 & 106 paved areas, including the E85 fueling area
Erosion Control
One retention pond exists on the NIEHS South Campus to control stormwater runoff from steep area located
between Building 104 and the Building 105 cooling towers. -Well-vegetated hill slopes surround the retention pond
and riprap is located downstream of the outfall to reduce the potential for erosion. In addition, a pipe has been
placed under the vehicle crossing point to reduce stream bed erosion. Stormwater discharge was clear at the time of
inspection.
Beavers continue to occasionally remove trees in and around the western finger of the NIEHS Lake. Some trees
' have been replaced in the Memorial Gardens area and are now protected with trunk barriers. Additional ground
cover is recommended for the southern portions of the Memorial Gardens as a restorative effort.
Vegetation coverage in the MR] area appeared satisfactory during the inspection. Vegetation coverage along the D-
' module shoreline near the picnic tables to the Fitness Center remains relatively unchanged since the previous
inspection. However, there is less evidence of shoreline erosion caused by geese accessing the lake. The shoreline
appearance across the lake from the Building 101 A -module Library is unchanged since the last inspection and
' remains eroded. Elsewhere, shoreline erosion is minimal.
Land Disturbing Proiects
Construction of a new Clinical Research Unit (CRU) modular building has been completed. The area surrounding
the CRU has been seeded and groundcover appears to have improved since the last inspection. The Building 105
boiler replacement project continues and the storage area adjacent to the west side of the building will require
' reseeding once the outdoor equipment associated with this project is removed. A project to install security boulders
across portion of the NIEHS campus has started. Ground cover impacts associated with this project will be
monitored to determine whether any restorative efforts are needed.
' Corrective Actions
The slump located along the fire lane just east of the MRI has partially collapsed and moved toward the NIEHS
Lake. The collapse caused the shoulder of the fire lane to drop about 18 inches and break away from the road bed.
A work order was submitted for repair of the slump. Grass cover remains acceptable since the ground surface has
remained mostly intact. This area will be reexamined during the next inspection. The Building 105 oil/water
separator discharge pipe has been rerouted underground to a small stormwater detention structure to reduce erosion
' on the hill slope located west of the building.
_Non-Stormwater Discharges
' Cooling tower overspray was found to be minimal. Otherwise, there were no non-stormwater discharges
discovered during this semi-annual stormwater conveyance system inspection, which was conducted on April 30
and May 4, 2009. Also, there have been no sanitary sewer overflows since March 2007.

NIEHS semi-annual stormwater conveyance system inspection (Fall 2009)

' Outfalls
Representative Outfall (Building 108)
' No non-stormwater discharges
Receives stormwater from Building 108 trench drain, Building 108 parking lot stormwater drain,
and some runoff from Buildings 105 & 106 paved areas, including the E85 fueling area
Groundwater from the trench drain valve box is discharged into rip -rap just below this outfall
Erosion Control
' One retention pond exists on the NIEHS South Campus to control stormwater runoff from the steep area located
between the Building 104 warehouse and the Building 105 cooling towers. Well -vegetated hill slopes surround the
retention pond and riprap is located downstream of the outfall to reduce the potential for erosion. In addition, a
' pipe has been placed under the vehicle crossing point to reduce stream bed erosion. There was no stormwater
discharge at the time of inspection.
Beavers continue to occasionally remove trees in and around the western finger of the NIEHS Lake. Some trees
have been replaced in the Memorial Gardens area and are now protected with trunk barriers. Recent tree damage
was not evident during this inspection. Vegetative cover between the lake and the southern portions of the
Memorial Gardens appears acceptable.
' Vegetation coverage in the MRI area appeared satisfactory during the inspection. Vegetation coverage along the D-
module shoreline near the picnic tables to the Fitness Center remains relatively unchanged since the previous
inspection. However, there continues to be less evidence of shoreline erosion caused by geese accessing the lake.
The shoreline appearance across the lake from the Building 101 A -module Library is slightly improved since the
last inspection but remains eroded. Elsewhere, shoreline erosion is minimal.
Land Disturbing Pro'ects
Construction of a new Clinical Research Unit (CRU) modular building has been completed. The area north of the
CRU has been reseeded and groundcover appears to have improved since the last inspection. The Building 105
' boiler replacement project is nearing completion and the storage area adjacent to the west side of the building has
been reseeded. A project to install security boulders across portion of the NIEHS campus has been completed.
Ground cover impacts associated with this project have been minimal. The area disturbed by the Cafeteria stairs
' replacement project has been reseeded. This area will be reevaluated next spring. The Building 104 fire hydrant
repair project is nearly completed with reseeding of disturbed groundcover expected within the next few weeks.
This area is also slated for reevaluation during the next inspection.
Corrective Actions
The slump located along the fire lane just east of the MR] has partially collapsed and moved toward the NIEHS
' Lake. The collapse caused the shoulder of the fire lane to drop about 18 - 24 inches and break away from the road
bed. A work order was submitted for repair of the slump. Grass cover remains acceptable since the ground surface
is mostly intact. This area will be reexamined during the next inspection. Groundcover was acceptable around the
' small stormwater detention structure associated with the Building 105 oil/water separator. The concrete structure
around the sanitary sewer manhole located north of Building 102 is cracked and will be reexamined during the next
inspection. A work order has been submitted for the removal of trees and weeds growing in the Building 105
emergency generator corral and near the Building 105 fuel oil storage containment.
' Non-Stormwater Dischar es
Cooling tower overspray was found to be minimal. Otherwise, there were no non-stormwater discharges
discovered during this semi-annual stormwater conveyance system inspection, which was conducted on October 20,
2009. Also, there have been no sanitary sewer overflows since March 2007.

Til:ulli you for the opportunity to review the draft stormwater permit. The NIEHS has reviewed the
permit and is providing comments in response to some of the limitations. The draft permit contains
Stormwater Pollution Prevention Plan conditions and analytical monitoring requirements that have been
strengthened. As such, the existing NIEHS plan must be revised to meet these requirements. The
compliance schedule in Part III, page 1 of 8 states that existing facilities applying for a permit renewal
shall annually update the stormwater plan. How much time is the NIEHS allotted in order to update the
existing plan, which was revised in June 2010?
The Certificate of Coverage designates the receiving stream "as a UT to Burden's Creek." The NIEHS
would like to have the 27-acre NIEHS Lake incorporated into the receiving stream name. For example,
the designation could be revised to "UT/NIEHS Lake to Burden's Creek" or "UT to NIEHS Lake to
Burden's Creek." This would emphasize the proximity and downstream location of this water body with
regard to facility operations.
The NIEHS was granted representative outfall status (ROS) for the Building 108 outfall. We would like
to have the sample location designated as ROS instead 'of stormwater discharge outfall (SDO) in Table 1:
Analytical Monitoring Requirements and in the associated footnote. This would limit analytical
monitoring to the Building 108 outfall only.
The qualitative monitoring requirements have been changed and the stormwater visual evaluation is now
to be performed during a representative storm event in conjunction with analytical monitoring. Does this
mean that the qualitative monitoring must also occur with the first 30 minutes of discharge? In addition,
the NIEHS requests approval to continue performing the qualitative monitoring at the representative
outfall location only.
Please let me know if you have any questions about our permit comments or if you would like additional
information about the NIEHS facility.

Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters, the name of the receiving water(s) to which the stormwater outfall(s)
discharges, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and accurate latitude and
longitude of the point(s) of discharge.
A copy of the general location map from the current NIEHS individual stormwater permit is
attached to the Appendix of this Plan as Figure I. This map includes all required information
such as transportation routes, surface waters, receiving waters, and latitude and longitude of the
discharge point.
(b) A narrative description of storage practices, loading and unloading activities, outdoor
process areas, dust or particulate generating or control processes, and waste disposal
practices.
Chemical waste, which is primarily generated within the Building 101 laboratories, is
appropriately labeled and packaged before being transported via carts from the laboratories to the
loading docks. The waste transport carts provide secondary containment and use absorbent pads
to collect any spills that may occur while in transit. The chemical waste truck transports this
waste from the loading docks to the chemical waste handling facility (WHF) located in Building
108. The chemical waste is processed and stored in Building 108 in preparation for incineration,
long-term storage or shipment to an approved offsite disposal facility. The waste storage areas
within Building 108 are segregated to keep incompatible materials separated while secondary
containment bins are used to store the chemical waste and prevent potential spills in the event of
a container leak. Also, there are no floor drains in the chemical storage areas and the floors
within each room are sloped to prevent spill migration both from room to room and to the
building exterior. The roofs covering the loading docks and the enclosed interior storage space
within the waste truck limit exposure to precipitation. The Building 108 loading dock area
includes a trench drain designed to prevent spilled chemicals from entering the stormwater
conveyance system. The trench drain valve remains in the closed position during normal
operations and is only opened to drain collected stormwater following a visual evaluation for
sheen and discoloration. There are no outdoor storage or process areas associated with the
NIEHS waste handling facility or any other NIEHS activities. A small sand pile stored outside
near the north side of Building 107 is covered with a tarp to prevent migration into the storm
drain system. This sand is applied to road surfaces to provide traction during icy conditions.
There are no other materials stored outside except for bulk petroleum products, which are
discussed at length in the NIEHS SPCC Plan.
(c) A site map drawn to scale with the distance legend indicating location of industrial
activities (including storage of materials, disposal areas, process areas and loading
and unloading areas), drainage structures, drainage areas for each outfall and
3

activities occurring in the drainage area, building locations, existing BMPs and
impervious surfaces, and the percentage of each drainage area that is impervious. For
each outfall, provide a narrative description of the potential pollutants that could be
expected to be present in the stormwater discharge.
Two site maps are included in the Appendix of this stormwater pollution prevention plan. The
first map (Figure II) provides a general overview of NIEHS Campus featuring the campus
buildings, location of loading docks, and the primary stormwater drainage routes. This first map
also indicates the location of Lakeview Drive, which is the road used by the chemical waste
truck to transport chemical waste from the laboratory loading docks to the Building I08 waste
handling facility. The second map (Figure III) features the representative stormwater outfall,
which is located just north of Building 108. Stormwater discharged by the representative outfall
travels through about 1000 feet of grassy and forested areas allowing for natural filtration of the
surface water runoff prior to entering the NIEHS Lake:
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three previous years and any corrective actions taken to mitigate spill
impacts.
There have been no significant spills or leaks of chemical waste into the stormwater conveyance
system during the previous three years. However, there has been one recent floor drain overflow
that resulted in a small discharge of cooling tower process water mixed with rainwater into an
unnamed tributary of the NIEHS Lake. The following table summarizes all spills and leaks that
have occurred over the past three years.

2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures.
(a) Feasibility Study. A review of the technical and economic feasibility of changing the
methods of operations and/or storage practices to eliminate or reduce exposure of
materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is not
practical, the stormwater management plan shall document the feasibility of diverting
the stormwater runoff away from areas of potential contamination.
The NIEHS has measures in place to eliminate or reduce exposure of chemical waste to the
stormwater system. These measures include covered loading docks, an enclosed waste truck,
and segregated waste storage with secondary containment within the Building 108 WHF.
Changing the methods of operation and/or storage practices is not necessary at this time.
(b) Secondary Containment Schedule. A schedule to provide secondary containment for
bulk storage of liquid materials, storage of Section 313 of Title III of the Superfund
Amendments and Reauthorization Act (SARA) water priority chemicals, or storage of
hazardous substances to prevent leaks and spills from contaminating stormwater
runoff. If the secondary containment devices are connected directly to stormwater
conveyance systems, the connection shall be controlled by manually activated valves
or other similar devices [which shall be secured with a locking mechanism] and any
stormwater that accumulates in the containment area shall be at a minimum visually

observed for color, foam, outfall staining, visible sheens and dry weather flow, prior
to release of the accumulated stormwater. Accumulated stormwater shall be released
' if found to be uncontaminated by the material stored within the containment area.
Records documenting the individual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a period
of five years.
Secondary containment exists for the bulk storage of fuel oil in all above ground storage tanks on
' the NIEHS Campus. Manually activated valves remain in the closed position at all times except
to release accumulated stormwater following a visual evaluation. Accumulated stormwater is
visually evaluated prior to release through the oil/water separators and into the stormwater
' conveyance systems. Records documenting the stormwater releases are maintained onsite for a
period of five years. The E85 tank, which contains 85 percent ethanol and 15 percent gasoline, is
double -walled and therefore considered to have secondary containment by design. The E85 tank
' pump, top -fill inlet, and bottom drain are all. designed with secondary containment and overfill
basins. Fuel oil and E85 are the only liquid materials stored outdoors in bulk at the NIEHS. The
Building 104 fuel oil tank and generator day tank are also double -walled. In addition, a
secondary containment deck has been provided for the waste cooking oil drums stored under the
roofline at the Building 101 A -Dock.
' (c) BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
' detention or retention, where necessary. The need for structural BMPs shall be based
on the assessment of potential of sources to contribute significant quantities of
pollutants to stormwater discharges and data collected through monitoring of
' stormwater discharges.
The NIEHS operates three oil/water separators that receive stormwater discharge from
' aboveground fuel oil storage tank containment areas. All containment valves remain in the
closed position until collected stormwater can be visually evaluated for sheen and discoloration.
Stormwater releases occur weekly or as needed with records kept in a logbook. This logbook is
' reviewed for completeness on a quarterly basis. In addition, all ASTs are equipped with locked
containment valves or locked fencing to limit access.
The representative outfall located at Building 108 directs stormwater into a forested area, which
provides natural filtration before the discharge enters the NIEHS Lake. A small retention basin
located onsite retains a portion of the roof drain discharges from Buildings 105 and 106 to reduce
stormwater flow into an intermittent stream that feeds into the NIEHS Lake. Rip -rap is located
along several stormwater conveyances to reduce flow and prevent erosion. These conveyance
systems are routinely examined to determine whether additional rip -rap is needed.
A high -hazard dam located onsite for stormwater control is maintained by the NIEHS. Water
held back by the dam creates a permanent 27 acre lake. Best management practices associated
with the dam include maintaining uniform vegetation cover, removing trees to avoid root
damage, and semiannual mowing to control overgrowth and vegetation type. The NIEHS has
6

contacted the NC Division of Land Resources and requested an official inspection of the dam to
review structural safety and operational compliance.
The NIEHS provides annual RCRA contingency, SPCC and stormwater management training for
all waste specialists, oil handling personnel and employees involved with facility operations,
maintenance and repairs. Annual drills are also conducted to evaluate spill response plans,
cleanup procedures and preventative maintenance activities.
Stormwater conveyances and controls are inspected at the minimum on a monthly basis. More
frequent inspections occur after heavy precipitation events or in the event of land disturbing
activities such as construction.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, a SPCC plan may be a component of the SPRP, but may
not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC may be incorporated by reference into the SPRP.
The NIEHS has implemented a Spill Prevention Control and Countermeasures (SPCC) Plan that
documents planning and response activities for fuel oil and E85 spills that are similar to those
chemical spill actions mandated by a SPRP. Therefore, the NIEHS SPCC is equivalent to a
SPRP with regard to fuel oil and E85 spill planning and response since these are the only liquid
materials stored outside in bulk at the NIEHS. Transport of chemicals across the NIEHS
Campus is not documented in the SPCC and will therefore be discussed as part of the SPRP
section of this Stormwater Pollution Prevention Plan. The SPCC Plan is maintained by the
NIEHS Health & Safety Branch and should be referenced for information concerning fuel oil and
E85 spill planning and response. The RCRA Contingency Plan is also maintained by the NIEHS
Health & Safety Branch and should be referenced for information concerning chemical spill
response at the Building 108 waste handling facility.
Supplies for controlling and cleaning oil and chemical spills are stationed at several locations
across the NIEHS Campus. Also, the Building 108 loading area is equipped with a trench drain
for containment of spills that can potentially occur during chemical waste transfer between the
truck and the loading dock. The trench drain valve remains closed at all times except to release
collected stormwater following a visual evaluation. The Building 108 parking lot is graded such
that runoff from the parking area adjacent to the loading dock does not enter the trench drain.
This minimizes the potential volume of stormwater entering the trench drain system in the event
that a spill occurs during precipitation.
Potential stormwater pollution sources not documented in the SPCC Plan include the possibility
of small chemical spills at the Building 101 and Building 108 loading docks. Spill supplies are
7

located in Building 1Q8, and at the Building 101 E loading dock to address this potential. The
loading docks at both locations are covered thereby minimizing the potential for a spilled
chemical to contact precipitation and enter the stormwater conveyance system. Also, the largest
container size for delivering chemicals to the Building 108 WHF is 2.5 gallons with most
containers less than one gallon. This relatively small container size also reduces the potential for
spilled materials to enter -the stormwater conveyance system.
Spill supplies are located in Building 105 and Building 106 as preparation for potential chemical
spills associated with water treatment products used in the boilers, cooling towers, chillers, and
the scrubber. Most chemical transfer operations in Buildings 105 and 106 occur indoors which
mandates a chemical spill response geared toward preventing materials from entering the
sanitary sewer system via floor drains. However, 55-gallon drums containing petroleum and
water treatment products are delivered to both Building 105 and Building 106 thereby providing
the potential for chemicals spills to enter the stormwater conveyance system. Spill supplies are
also located in bins situated outside of Building 105 near the fuel oil loading area and adjacent to
the E85 storage tank. A table (Figure IV) documenting locations of spill supplies is located in
the Appendix. The spill action plan established for responding to chemical spills is also attached
to the Appendix of this SPRP as Figure V.
The chemical waste truck is also a potential source of leaks and spills that may enter the
stormwater drainage system during chemical waste transport from the Building 101 loading
docks to the Building 108 WHF. The chemical waste truck also delivers boxes of packaged
chemical waste from Building 108 to Building 106 for incineration. The chemical waste truck
route when combined with the routes of other chemical delivery vehicles involves nearly the
entire NIEHS Campus system of -roads. The Building 108 WHF receives waste from both the
NIEHS and the EPA, with the EPA waste typically transported by truck via Facilities Lane. A
map (Figure 11) depicting the major NIEHS stormwater drainage routes is attached to this Plan
to provide guidance as to the general direction of flow for large chemical spills or for those spills
which occur during precipitation events.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.
The loading docks and the cargo space within the chemical waste truck are kept clean and
orderly. Also, chemical waste is not stored in unroofed areas and is not stored on the chemical
waste truck. The integrity of the transport carts, secondary containment bins, and spill control
equipment is evaluated on a monthly basis. All waste materials are tracked from the point of
generation to the point of disposal. The fuel oil containments are inspected on a weekly basis to
determine whether any maintenance activities are necessary and to visually evaluate stormwater
prior to release. Facility inspections are conducted on a monthly basis to determine whether
there are any non-stormwater discharges.
(a) Storm Drain Policy

The storm drain system is designed to efficiently remove stormwater from NIEHS roadways,
parking lots, and low lying areas during precipitation and snowmelt events. The majority of the
storm drains on the NIEHS Campus direct runoff water toward the lake. Disposal of beverages,
trash, and other materials into the storm drain system that may contaminate or obstruct
stormwater discharge is prohibited.
(b) Non-stormwater Discharge Policy
A non-stormwater discharge is water runoff from sources unrelated to natural precipitation
events. Non-stormwater discharges are considered authorized or unauthorized depending on the
origin of the discharged water. The following section describes the policy associated with the
different types of non-stormwater discharges that may occur on the NIEHS campus.
(i) Authorized non-stormwater discharges:
Fire suppression systems
Discharge of water into the stormwater drainage system from. fire hydrants and tanker trucks
during fire -fighting or fire -fighting training is authorized. However, containment measures are
required if the HSB determines that the runoff is potentially hazardous to the environment.
Water discharged during fire hydrant and sprinkler system flushing is also authorized. Efforts
must be made to limit the potential for erosion caused by hydrant and sprinkler flushing.
Potable water
Discharge of uncontaminated potable or city water is authorized. This includes water that is
flushed, leaking, or otherwise discharged from the domestic or city water system. Large potable
water leaks must be reported to the HSB. Routine washing of building exteriors and windows
with potable water is authorized as long as no detergents are used. Potable water may also be
used to rinse vehicles as long as water use is minimized to limit the volume of water discharged
to the storm drain system
Air conditioning & atmospheric condensate
Discharge of uncontaminated air conditioning condensate is authorized. Uncontaminated water
discharged from atmospheric condensation and from foundation drains is also authorized.
Valve pits/utility vaults groundwater pumping
The pumping of uncontaminated groundwater from valve pits and utility vaults into storm drains
or onto the ground is authorized. Efforts must be made to limit the potential for erosion caused
by surface water runoff from groundwater pumping.
Landscape watering
The watering of plants and vegetation in the landscaped areas on the NIEHS campus is
authorized. Landscape watering should be efficiently directed in order to limit overspray and
avoid discharges into storm drains.
(ii) Unauthorized Non-stormwater Discharges:
01

Sanitary sewer system leaks
' Sanitary sewer system leaks must be reported to the NIEHS Security office at 1-2800. It is
recommended that wastewater from the overflowing manhole be pumped to the nearest
downstream manhole to reduce the release volume. Efforts should be made to reduce
' wastewater discharge from upstream sources during overflow events. Also, wastewater must not
be pumped out of the overflowing manhole onto the ground in an effort to evaluate sewer line
conditions. The NIH Office of Research Facilities (ORF) is responsible for requesting an offsite
' contractor to clear the sewer line in the event of blockage that results in an overflow.
Vacuuming must occur with any jetting of the sewer lines. The HSB Environmental Compliance
Officer is responsible for notifying Durham County and the NC Division of Water Quality of any
' changed condition or discharge to the environment. The HSB Environmental Compliance
Officer is also responsible for submitting a press release to all Durham County print and
electronic news media if an untreated wastewater discharge of 1000 gallons or more enters the
' NIEHS Lake. The HSB and/or the ORF landscape contract project officer are responsible for
disinfecting the spill site through application of hydrated lime and removal of excess solids.
' High Temperature Hot Water (HTHW) line breaks
HTHW line breaks must be reported to the HSB to allow for review of potential environmental
impacts and to document the event. Water treatment chemicals within the HTHW system are
' volatilized upon contacting the atmosphere during leaks and line breaks. The recommended
method for HTHW disposal, after it has condensed and pooled, is through pumping into the
sanitary sewer system or onto the ground surface. However, water from HTHW leaks must be
' cooled to less than 100 degrees Fahrenheit prior to pumping from valve pits, utility vaults, and
other contained locations.
Chilled water system
Chilled water leaks that flood a valve pit, utility vault, or other containment area must be
reported to the HSB. The recommended method for chilled water disposal is through pumping
water from the valve pit into the sanitary sewer system. However, the HSB determines the
appropriate disposal method on a case by case basis.
' Cooling tower basin leaks & overspray
Cooling tower basin leaks and overspray are considered to be sources of unauthorized non-
' stormwater discharges. Efforts should be made to limit the amount of overspray, splashing, and
leaks from the NIEHS cooling towers.
Building and window washing
Water that contains detergents used in the exterior building and window washing process must
be disposed offsite by the cleaning contractor or disposed onsite via the sanitary sewer system.
' Disposal of water contaminated with detergents or other cleaning agents into the stormwater
drainage system is prohibited. Prior approval must be obtained from the HSB before onsite
disposal into the sanitary sewer system can occur.
' Vehicle washing
1
10

Vehicle washing that involves detergent usage is generally prohibited on the NIEHS campus
unless the activity occurs in an area where wash water can be discharged to the sanitary sewer
system. The weekly disinfection of the CMB research animal delivery van is an example of this
policy. The HSB has requested that this activity, which involves use of a detergent -based
disinfectant, occur inside Building 106 near the floor drains in order to provide disposal via the
sanitary sewer system.
Vehicle maintenance activities
Vehicle maintenance activities are prohibited since motor oil replacement, cooling system
flushing, and other types of vehicle repair and servicing increase the potential for spills that can
lead to an unauthorized non-stormwater discharge. Fluids leaking from vehicles parked onsite
are reported to the HSB to generate a cleanup response and prevent stormwater contamination.
5. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel
(or team) responsible for implementing the training shall be identified.
RCRA Contingency, SPCC Plan and stormwater management training is conducted annually.
This training discusses proper spill response, cleanup procedures, and preventative maintenance
activities. The Environmental Compliance Specialist is responsible for implementing
stormwater training. Spill response drills that simulate leaks or spills of chemicals stored onsite
are conducted on an annual basis. These drills typically assess spill response, adequacy of
cleanup materials and communication between the adjacent EPA facility and the NIEHS.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
The stormwater plan coordinator and other personnel involved in implementing this Plan are
listed in the following table. An emergency contact list is provided on the first page of this Plan

7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance, which has a significant effect on the
potential for the dischargd of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
' The Stormwater Prevention Plan is reviewed and updated on an annual basis and the NC
Division of Water Quality is notified in writing of any changes that may impact the stormwater
' conveyance system. Amendments to the Plan for the year 2010 include the updated training and
inspection dates.
There were no modifications to the NIEHS stormwater conveyance system during 2009. An
application has been submitted to the North Carolina Division of Water Quality for renewal of
the individual stormwater permit. Quarterly stormwater sampling is not required until the
Stormwater permit terms have been established.
8. Facility Inspection Program. Facilities are required to inspect ail stormwater systems on
' at least a semiannual schedule, once in the fall (September - November) and once in the
spring (April -- June). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be
incorporated into the Stormwater Pollution Prevention Plan.
Bill Steinmetz conducted semiannual Stormwater conveyance systems inspections in April and
October of 2009. The results of those inspections are attached to this plan.
9. Implementation. The permittee shall document all monitoring, measurements,
inspections and maintenance activities and training provided to employees, including the
' log of the sampling data and of activities taken to implement BMPs associated with the
industrial activities, including vehicle maintenance activities. Such documentation shall
be kept on -site for a period of five years and made available to the Director or his
authorized representative immediately upon request.
' Bill Steinmetz is the file custodian for all stormwater related correspondence produced and
received by the NIEHS. These files include letters, sampling results, and inspection results,
along with current and former stormwater permits. There are no vehicle maintenance activities
' performed onsite. The NIEHS stormwater files are available for review by the North Carolina
Division of Water Quality upon request.

7. Analytical Monitoring Notes:
o There have been a number of exceedences in Aluminum, and one in COD. Monitoring was only
required in the first and last year of the permit — quarterly. This will change in the new permit to semi-
annually.
o When 624 and 625 were tested — outfall 2 exceeded Human Health for PAHs and Freshwater Standards
for Fluoranthene. 624 and 625 need to be continued,
o COD will be kept in the permit. BOD will also be added as Chlorophyll a is part of the TMDL for
Jordan Lake.
o Jordan Lake Rules and Jordan Labe TMDL require monitoring of TN and TP to identify existing
pollutant sources in these watersheds. 'these will be added to the permit. See attached information
on Jordan Lake Rule Summary and Jordan Lake Rules for more information in background.
o This site may be a good candidate for monitoring acute toxicity of sw -- especially coming from roof
drains where incinerators are exiting above those roofs. However, we are riot ready to incorporate acute
toxicity monitoring into this permit as of yet, and I think that we should see how it works at other
facilities and perhaps implement in the next monitoring scheme.
o RRO needs to re-evaluate representative status.
8. Qualitative _Monitoring Notes:
o 8 Petroleum spills since 1978.
9. Other:
o ROS was granted for outfalls — see Q/A section of this document below. FAO has been to the site
recently and initiated, recommended and was the entity to grant ROS. See answers below in the Q/A
section of the document for more details. Central Office does not want to second -Mess the RRO, but
would like to recorwnend that the outfall from the pond also be monitored. Please call the central
office regarding the placement of monitoring [also sent message to RROI.
o Burden's creek was changed from class C to W S-IV

Revised Permit Recommendations: Analytical Monitoring:
1. Adding to Permit: Oil & Grease, 624, 625, ROD, TN, TP, Al, pH.
2. Remaining in Permit: COD, pH, Aluminum, Qualitative
3. pH has been added to the analytical monitoring requirements.
4. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part II
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30 days
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
5. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase record keeping, and/or
install stornwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
6. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defiled in Part ll Section B. Qualitative monitoring is required regardless of representative
outfall status.
7. The permittee is responsible for all monitoring until the renewal permit is issued. See footnote l of "fables 1, 4,
and 5.
S. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
9. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
l . Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is unpaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall, The map requirements are stated more explicitly. And, the site plan mustcontain a list of significant
spills that have occurred in the past three years and also must certify that the outfails have been inspected to
ensure that they do not contain non-stonnwater discharges. Additional information is provided in Part II Section
A.
2. Additional requirements for the Storinwater Management Plan have been specified in Part 11 Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stornnwater Pollution Prevention Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stornwater discharges.
4. T`he facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR § 122.26(g), the f-acility may qualify
for a No Exposure Exclusion from NPDES storinwater discharge permit requirements. Additional information
is provided in Part I Section A.

Discussions with permittee: Bill Stienmetz L NIEHS, Environmental Compliance Specialist, 919-541-4234
Called April 15, 2009. Left message.
Notes on NIEHS conversation with Bill Stienmetz, April, 2009.
Their permit was up for renewal — approaching 2 years. And they found out about no exposure certification in
meantime but have waste handling facility. Had some elevated aluminum readings — sand that was supplied for ice?
They have 40 million bTU boilers and 3 incinerators: 1 that runs M,W, Th and 2 that rarely runs — maybe 4 days a
quarter max. Last year they incinerated. They have a scrubbers on the main one. The rnain one is for the waste
treatment for the lab (lab waste, animal carcasses (small waste), animal bedding (# 1), non -regulated chemical, very
small amount of medical waste) others are decayed radioactive — P32 — isotopes that have a short half life.
Boilers: 3 boilers are each 40 million btu — they are natural gas with fuel oil #2 as a backup. Natural gas is piped —
fuel oil has secondary containment. Never used coal. They had 2 old boilers that could have burned coal and oil but
it was reported that they did not — and they have since been removed.
Q; 0wi tvpes o1'1hings are the lab waste?
None is haz waste. Packaging, paper, glass, they encourage recycling but not all, recycling, small amount of
municipal waste.. They have a chemical waste pickup — and all chemical waste goes to a system — they take out
to a dock area and it goes to building 108 — there determined if they can store or burn or sent offsite. What
kinds of things would they burn? Media, buffers (from running gels). Etc.
Liquids from research goes to either pathological or municipal solid waste. Any not chemical is municipal solid
waste and goes to the incinerator.
Q: What is considered to be chemical?
Any used liquid that is not needed — or is used. That is picked up by contract agency. That all goes to 108 for
sorting. Typically they do not mix — give to waste in the same container or by adding -the same material.
1. What other permits do you have?
Have Air quality permit with NC. Have RCRA permit. Have a local discharge permit with Durham
County for waste water. NR.0 license — use of radioactive materials. 2 of AST have a certificate of
registration — Art Mouberry in DWQ — That is a one-time registration and certificate of registration for
facility in Aquifer protection. For Durham County have a class D Haz Materials permit with Durham
County Fire Marshalls office. No NPDES WW permit. "Their WW goes into pipe to the county. They
have some small pre-treatment (grease traps, Hg removal for incinerator, and silver trap for photo lab).
But no large pre-treatment or package plant,
2. Q: Please send a copy of your permit and tell me what you are currently monitoring for as we do not have one in
the file.
a. ANSWER: He has the old permit and will scan and send to me has seen the representative outfall status
letter and will look for and try to send to me.
3. Q: What is the frequency of monitoring using 624 and 625?
a. ANSWER: Not any more.
4. Were the things you tested for in 624 and 625 standard for those tests or were they tests for what you were using?
a. He does not know why they were tested for.
b. They had a large oil spill in 1990. Could be because of this,
c, In current pen -nit have COD, Al and p1l. He will send me the copy of the old permits as well.

5. Q : Please describe outfall paths and discharges to these areas:
a. Roof drain discharge: directly to storm drains into underground to NIEHS lake
b. Haz waste areas: To trench drain.
c. Oil water separator: piped to NIEHS lake
d. Retention Pond: There is the large lake and a retention pond. It was to slow down water that came form the
roof drains to 105 and 106. Some of the roof drains go to that pond and the drainage ditch.
e. What is the Intermittant stream from retention pond? Water is trickling out of the pond goes into the lake.
That is looked at twice a year during the semi-annual inspections.
6. Q : Please describe how many outfalls you have an outfalls in detail and monitoring:
a. ANSWER: see below — have one outfall. Have ROS,
7. Q: Please describe discharge from haz waste areas, what is stored there, and what outfall this goes to:
.a. ANSWER: Loading dock is covered with a roof and the trench train . The trench drain has a drain valve.
Not locked but kept closed. This was started recently. Previously it was left open. Rainwater can enter.
Part of the peak it can rain on it and go back to the trench drain. If they have a spill,that is noted in an SOP
and it is noted on a form. They have not had a spill other places on campus — and have been all petroleum
products.
8. Q: Please describe discharge from oil/water separators and what outfall this goes to:
a. ANSWER: There is discharge from that. There are 3: those go that discharges to a grassy area. The
discharge goes into a wooded area into a drainage ditch, About a thousand feet. The others are at 101 C and
101 F, and that goes directly to an underground stormwater piping to a lake. The valves are kept closed and
locked and they look at it for oil and sheen and that is before it enters the lake. Only from those 3
containments. Those 3 are not double walled and those are the 3 or 4 largest tanks for fuel oil -- one is for
emergency generators and one for boiler fuel oil.
9. Q: 1 don't have any monitoring between 2001 and 2005. Why?
a. ANSWER: They switched over to a 4"' year monitoring of the permit.
10. What is the research being done in bldgs?
a. Environmental health research — mostly using mice. The chemicals for research come into building 101.
There are probably about 10,000 chemicals but very small amounts — a gal is a very large amount. The
drains for the dock of 101 are traditional storm drains.
11. Do you have a procedure in place for a spill
a. They have a RCRA permit and procedure. Have a sppp for petroleum. The responders are all trained and
have drills.
12. Have you had a spill over there in loading and unloading?
a. No. Only petroleum spills, Those mostly during fuel oil delivery.
13. Are there Roof vents from research bldg's?
a. Yes — from hoods. Most of those are not controlled. Several hoods can combine together and can vent out.
Some have carbon but most do not. Roof drains and the headwall is directly onto the lake. None of the
building have a guttering system — they all have a spout directly into the lake. Piped underground.
14. Are there stacks on the incinerator bldgs and boiler bldgs? Where does that drain to?
Page I l of 13

NCS000360
a. Yes — see below and question above.
15. Do you monitor SW coming off roof drains from boiler and incinerator bldgs?
a. No do not monitor stonnwater coming off the roofs of any buildings.
16. You have Representative outfall status — what Qutfalls is that for? i.e. what outfalls are now not monitored?
a. Yes. See map in file. Monitoring by building 108.
17. Please send a map with numbered outfalls marked on it
a. See map.
18, Have you added rip -rap to end of conveyance systems to reduce flow to NIE14S lake?
a. Yes. Where is that? One is by building 101. They had a concrete conveyance at the point where it .].tits the
lake. They had another one they replaced that was at the north side of the building where the stonnwater
pipe comes back to the next pipe. That had been filled up with soil but has been cleaned up and was
replaced.
19. Has all Haz waste TSD been closed down? Bldg 106 was but is 108"'
a. They are still a haz waste called a waste handling facility— WHK They do not receive any haz waste
from other facilities. They share some operations with the EPA. Part is NIEHS and part is EPA. But
they manage stonnwater permit. They share the incinerator and the electricity bill with the EPA.
20. Are you only sampling for outfall at bldg 108 — nothing at the bldg 101 on the North side of the lake?
a. No.
21. This says NIEHS South Campus — do you have another permit for another campus in NC? RTP?
a. No.
22. The incinerators are in building 106.
a. Have you been up on the roof?
i. Yes.
ii. There are incinerator stacks. The roof is fairly clean. They don't have much problem with
smoke. Roofs were replaced in 2003 and 2004. The roof drains go to gutters and piped out
towards the lake.
23. What about your Haz Waste?
a. All waste is in 104 or 105. They do have some waste that is designated as haz waste. They no longer
burn haz waste material in incinerators. All incinerators are in 106 and main incinerator has scrubber
and carbon bed. The two others do not.

Summary of the Jordan Nutrient Rules
August 14, 2009
Strategry Synopsis and Status
The proposed B. Everett Jordan Reservoir Water Supply Nutrient Strategy is a
comprehensive set of rules designed to address excess nutrients in Jordan Lake that can lead
to algae blooms and other water quality problems. Jordan Lake is an impoundment in the
central Piedmont that drains a mixture of agricultural and urbanized lands forming the upper
Cape Fear River Basin, including the west side of the 'Triangle and much of the Triad region.
The lake serves as a water supply for the Town of Cary and also has significant recreational
use. The rules are similar to those already in place in the Ncuse and Tar -Pamlico River
Basins. The rules would require all major sources of nutrients to reduce their loading to the
three arms of Jordan Lake to meet specific percent reduction goals, established through
modeling, that are needed to restore water quality standards and full uses of the lake.
Nutrient sources addressed by the rules include agriculture, fertilizer application, wastewater
discharges, and stormwater runoff from both new development and existing developed lands.
Local governments would be required to reduce the discharge of nutrients from wastewater
treatment plants and implement programs to address nutrient pollution from both existing and
new development. The nutrient management strategies implemented in the Ncuse and Tar
Pamlico river basins do not address pollution coming fi•om existing development. A strategy
fist' existing development was needed in the Jordan Lake watershed because of the significant
nutrient contributions from developed lands in this watershed. Also new is a separate trading
rule that would allow use of the most cost-effective management options to meet the goals.
The set of thirteen Jordan nutrient rules was approved by the Environmental Management
Commission in May 2008, followed by approval of the Rules Review Commission over five
meetings from June through November 2008, The rules were then reviewed by the 2009
session of the General Assembly, having all received the requisite number of objections
during the RRC process. Five of the rules were either replaced or revised by legislation, and
the remaining rules were approved by the General Assembly unchanged. Prior to the EMC
undertaking rule -making, a modeling process was initiated by the Haw watershed dischargers
in 1998, and was followed by an extensive stakeholder input process begun in 2003 and
carried through the formal public comment period in sununer 2007.
Lake History: The potential for excess nutrients was recognized when B. Everett Jordan Reservoir
was proposed in 1945. The reservoir was approved by Congress in 1963. After years of construction
delay due to projected water quality concerns, the lake was impounded in 1983. It was designated a
Nutrient Sensitive Water that same year by the Environmental Management Conurrission. The lake
has consistently tested as eutrophic or hyper-eutrophic since impounded, indicating high to excessive
levels of nutrients in the water. Nutrients make their way to the lake from sources such as
wastewater discharges, rainfall runoff from agriculture, and stormwater runoff' from new and existing
developed lands. Excessive nutrient inputs drive excessive growth of microscopic algae, which
imparts a greenish, murky appearance to the water, causes taste and odor problems in finished water,
and robs the water of oxygen, stressing or killing fish and other aquatic life. Excess nutrients also
favor the growth of undesirable algae that does not support the food chain and can release toxins into
the water. While not necessarily making the lake unfit for fishing, swimming, or drinking uses,
excess nutrients are impacting these uses, and undesirable algae are present in the lake. While only

V�—
one fish kill has been reported to date, taste and odor problems prompted Cary to add chemical
treatment to its drinking water process, and unsightly, smelly water deters swimmers, boaters, and
other sportsmen.
In 2002, the Division of Water Quality determined that the Upper New Hope Creek Arm no longer
met its designated uses due to exceedences of the chlorophyll a standard, which measures algal
growth, and in 2006 made the same determination for the rest of the lake. The Haw River arm was
also impaired in 2006 for pH exceedences. Both parameters are indicative of excessive nutrients.
These impairments place the reservoir on North Carolina's list of impaired waters under Section
303(d) of the federal Clean Water Act.
Regulatory Mandates: The Clean Water Responsibility Act of 1997, Session Law 1997-458,
required the EMC to set concentration limits on wastewater facilities discharging to Nutrient
Sensitive Waters. The next year, Session Law 1998-212 allowed the EMC to grant a compliance
extension if a facility chose to develop a calibrated nutrient response model for the water body and
adhere to the results. The Clean Water Responsibility Act also required the EMC to set restoration
goals for nutrient -impaired waters, require steady progress toward those goals and impose nutrient
reduction measures in a fair, reasonable, and proportionate manner on point source and nonpoint
sources relative to their contributions. In 2005, the General Assembly also enacted SL 2005-190 that
directed the EMC to adopt rules to establish and implement nutrient strategies to protect drinking
water supply reservoirs. In addition to state requirements, the determination that the reservoir has
impaired water quality triggers federal Clean Water Act requirements to set and enforce nutrient load
reduction limits, known as a total maximum daily load (TMDL).
Rulemaking Process and Public Comments: To comply with the Clean Water Responsibility Act,
wastewater dischargers in the Haw River watershed developed a reservoir model in the late 1990's to
estimate the lake's nutrient reduction needs. The EMC approved the reservoir model in 2002. During
2003-2004 Division staff conducted a 1-% year, 22-meeting stakeholder process to apply the
reservoir model and seek a consensus on lake nutrient loading goals, discharger allocation methods,
and a conceptual nonpoint source strategy. In 2005, staff solicited public comment on a rules
framework and brought draft nrles before the FMC's Water Quality Comtnittec, in January 2006,
the committee directed staff to conduct additional stakeholder meetings, which continued thru 2006.
A TMDL for the entire reservoir was approved by the EPA in August 20071.
Pursuant to the-EMC's authorization of draft rules in March 2007 and subsequent notice in the North
Carolina Register, the Division held three public hearings and provided a 9b-day written comment
period from June 15 through September 15, 2007 on the proposed rules. Approximately 400 peoplc
attended the hearings, 150 of whom spoke, Staff received more than 7,000 documents, postcards, and
ernails providing written comment. A detailed, 80-page commenter -indexed summary of all public
comments along with staff replies is provided as Appendix D of the Report of Proceedings.
There were strong objections to the rule from various parties, especially from local governments and
development interests, particularly concerning the need and effectiveness of the proposed rules.
There were unresolved issues with the model and the data used. Many also felt that the Haw
communities would pay for the benefit of New Hope communities who withdraw water from the
t Report or other supporting docunient(s) available on DWQ's Jordan nutrient strategy website, at
ht_tJr;, llr2o.c nr. t<itc.nc.jishipslJorcltinlVufricnlStrtaleg<<.hlrx?.

��V
fake. The most contentious parts of the strategy were the potentially precedent -setting Existing
Development Rule, and the wastewater nitrogen compliance date.
At the same time, there was support for the rules from environmental groups and lake users.
Supporters cited a longstanding need for restoring the lake, federal and state mandates, eroding
quality of their lake use experience, the general importance of the lake, and the collateral benefits to
numerous degraded streams in the watershed.
Nutrient Management Strategy Design: The strategy is designed around nitrogen and phosphorus
percentage reduction goals for each of the three arms of Jordan Reservoir because each ann of the
lake responds independently to nutrient inputs received from its watershed. For example, goals for
the Haw Arm of Jordan Lake and corresponding reduction requirements for Haw watershed sources
are driven by existing nutrient inputs from those sources. State law requires fair, reasonable and
proportionate requirements, so each category of sources in a given watershed faces the same
percentage reduction requirements relative to its baseline inputs. The rules are designed to give all of
the regulated entities maximum flexibility in meeting the reduction goals. One key addition to
maximize options is a new, separate trading rule that provides load -reducing options across regulated
sources. Nutrient sources addressed by the rules include agriculture, fertilizer application,
wastewater discharges, and storniwater runoff from both new development and existing developed
lands. Local governments would implement the wastewater and development rules, including
requirements to protect existing riparian buffers. The existing development component, not included
in previous strategics, is necessitated by the significant nutrient contributions from developed lands
in this watershed. The strategy also recognizes the importance of adaptive management, and
provides for periodic review of the lake's recovery progress to inform potential management
revisions.

Rules Content: All rules fall under T15A NCAC 2B. The following is a brief summary of each of
the thirteen rules:
o Rule. 0262, Purpose and Scope
Describes strategy purpose, scope, and objectives; identifies the set of rules comprising the strategy;
designates Jordan watershed as a `critical water supply watershed', which allows the EMC to require
more stringent measures than minimum Water Supply Watershed requirements; defines geographically
the three subwatersheds draining to Jordan Reservoir; identifies the baseline time period; establishes
nitrogen and phosphorus (N and P) percentage reduction goals and corresponding point and nonpoint
source lake loading targets for each am relative to the baseline; establishes that all local govertnnents --
eight counties and 26 municipalities— are subject to certain rules; and provides for adaptive management
following a period of implementation. Each subsequent Rule references parameters set forth in this Rule.
❑ Rule .0263, Definitions
Defines terms that apply across rules and are specific to the set of Jordan rules.
Ci Rule 0264, Agriculture
Establishes collective nitrogen and phosphorus reduction goals for agricultural operations in the
watershed. The goals include numeric thresholds for livestock operations. Three years after effective
date, the Watershed Oversight Committee (formed by the Director) will determine the extent to which the
nitrogen goal has been achieved relative to the baseline period. if the goal has not been achieved, Local
Advisory Conunittecs (LACs) must be formed to develop a strategy to meet the goal. Six years aficr
effective date, the EMC will determine whether LACs have achieved subwatershed N and P goals based
on collective implementation. if not. the EMC will require additional BMP implementation as deemed
necessary to achieve the goals within nine years after effective date. The Rule allows trading of
reductions that exceed collective compliance goals. Annual reports are required.
o Rule. 0265 & SL 2009-484, Stormwater Managementfor New Development (
Requires all local governments in the Jordan watershed — eight counties and 26 municipalities — to
implement stormwater programs for new development activities. Those programs must be designed to
meet nutrient loading rate targets. Developers will be required to control nutrient export to certain levels
offite, but can meet remaining reduction needs through offsite measures including payment of fees for
nutrient offset projects or through purchase of reduction credits from private sellers pursuant to the Jordan
trading rule .0273. Within eighteen months after effective date, the Division submits a model local
program to the EMC for approval. Within another six months, local governments submit programs for
Division review and EMC approval. Within three years after effective date, local governments implement
permitting requirements. Annual reports are required. This rule will be rewritten to incorporate the
changes of SL 2009-484.
❑ Session Law .2009-2I6
The original Existing Development Rule (.0266) that was sent to the General Assembly was disapproved.
However, the rule was replaced and approved by Session Law 2009-216, with an effective date of June
31, 2009. The Session Law retains the basic requirement that nutrient reductions are to be obtained from
local government's existing development. The bill requires all local governments in the watershed to
develop a Stage 1 adaptive management program by December 31, 2009. This program will contain
sirlular measures of the Phase Il stonnwater prograin, and also requires the identification of opportunities
for retrofits and other nutrient reduction projects from existing development. The Division is required to
develop a Model Stage 2 adaptive management program no later than July 1, 2013. The rule also calls for

an ongoing monitoring program, and OWQ is tasked with providing monitoring reports to the
Commission every three years beginning in March 2014. if water quality standards are not met in the
UNH arm by the March 2014 report, or in the UNH and Haw arms by the March 2017 report, or any
subsequent reports, the Division will notify local governments within the impaired arm of their need to
develop a local Stage 2 adaptive management program. Within six month of notification, local
governments will submit their stage 2 programs to the Division. Within another six months, the Division
will review the programs. The stage 2 programs will essentially contain the same requirements as the
original rule: local governments will be required to reduce nutrient loading from existing development to
meet the subwatershed goals. A difference from the original existing development rule is that an 8%
nitrogen and 5% phosphorus reduction will be required from all three subwatersheds. However, if the
UNH does not achieve water quality standards by March 2023, the local goverrrrnents in that
subwatershed will be required to revise their program to achieve a 35% reduction in nitrogen. Annual
reports will be required. The Session Law also calls for the Director to form a Scientific Advisory Board
by July 2010. This board will be tasked with identifying management strategies, evaluating the
feasibility, costs, and benefits of the strategies, developing an accounting system, and identifying the need
for improvement or refinements to modeling and other analytical tools used to evaluate water quality.
The Existing Development Rule will be rewritten to be substantively identical to the Sections in Session
Law 2009-216 that cover existing development.
o Rule .0267, .0268, .0269 & S. L. 2009-484 Protections of and Mitigation: for Lkistiing Riparian
Buffers
Requires local governments to implement programs to protect existing vegetated riparian areas within 50
feet of and adjacent to intermittent and perennial streams, lakes, and ponds in the Jordan watershed. The
first 30 feet adjacent to waters is largely undisturbed forest, while the outer 20 feet may be managed
vegetation. F,xisting, ongoing activities within buffers may continue as long as these activities or uses
meet the requirements of the rule, while a change in land use invokes the protections. These buffer
requirements replace those under the current Water Supply Watershed rules, and provide local
governments the option to require more stringent measures. Certain activities within the buffer are
identified as exempt, allowable, or allowable with mitigation, while uses not listed are prohibited. The
rules provide mitigation options (buffer restoration, land conservation, or mitigation fee payment) where
no practical alternatives exist; as well as variance provisions. The Division of Water Quality implements
the rule for activities conducted: by local governments; state or federal entities; agriculture; forestry; and
in areas where no local buffer program currently exists. Rule .0267 will be rewritten to incorporate the
changes of SL 2009-484.
❑ Rule .0270 & S.L. 2009-216, Wastewater Discharge Requirements
Distributes the total point source annual N and P mass loading goals for each arm of the lake in the four
of annual mass allocations to existing wastewater dischargers within each of the three subwatersheds.
Discharge concentration equivalents at full flow range from 3.04 mg/L TN and 0.23 mg/L TP in the
Upper New Hope Ann to 530 mg/L TN and 0.67 mg/L TP in the Haw River Arm. As in the Neuse River
Basin nutrient strategy, there are provisions for new and expanding discharges; an option for group
compliance; and potential for in -lieu fee payments to offset excecdence of the annual loading cap. There
is also an option for transfer of allocation among individual dischargers. Phosphorus compliance date is
the first full year after effective date, while the nitrogen compliance date was revised from 2014 to 2016
by Session Law 2009-484. This rule will be rewritten to incorporate the changes of SL 2009-216.
zi Rule .0271 & S.L. 2009-484, Stormwater Requirements fir State and Federal Entities
Establishes storrnwater requirements for state and federal entities that are similar those imposed on local
governments for both new and existing development under rules .0265 and Session Laws 2009-216. The

NC DOT is treated differently than other state/federal entities based on the unique character of its
activities. Annual reports would be required. New DOT road projects would be deemed compliant if
they meet buffer protection rule treatment criteria. Existing development for state and federal entities will
parallel Session Law 2009-21 G above, except there will be no stage 1 program, and entities in the LNH
will only be required to maintain no increases in nitrogen and phosphorus loads from existing
development if adaptive management programs are triggered. DOT is also given the option of
implementing a combination of three stormwater retrofits per year for existing roadway development and
other load -reducing measures identified in the program to control loading from existing development
pursuant to .0271, This rule will be rewritten to incorporate the changes of SL 2009-484.
❑ Rule.0272, Fertilizer Management
Beginning three years after effective date, the application of fertilizer to lands in the watershed is to be
done either by applicators who have completed nutrient management training offered by the Cooperative
Extension Service, or pursuant to a certified nutrient management plan developed for the lands to which
fertilizer is applied. Also requires property owners to ensure that applicators to their lands have met one
of these requirements. The role does not apply to fertilization of residential lands done by the
homeowner. Wastewater residuals and septage application have earlier compliance timeframes. Animal
waste application in compliance with a permitted waste utilization plan is deemed compliant.
❑ Rule .0273, Options for Offsetting j1'utrient Loads `
Provides parties subject to the various rules - new development, existing development, State and Federal
stormwater entities, agriculture, and point sources — the option to obtain more cost-effective reductions by
purchasing reduction credit from other, offsite reduction sources or private sellers. This open, market -
based framework provides options in addition to the NC EEP option currently used in the Neuse and -Tar -
Pamlico strategies. It requires that minimum onsite standards be met before seeking credit elsewhere. It
sets criteria for those seeking to sell excess reductions, and would require Division approval.

Dear Mr. Stienmetz:
The Division of Water Quality's (DWQ) Stormwater Permitting Unit (SPU) received a comment letter
regarding DraP. liermit NCS000360 on July 6, 2010. After' conferring with the Raleigh Regional Office,
the `3tp.-•._±.water Pr:•,nitting Unit responds to your comments as follows:
Q: "The compliance schedule in Part III, Page 1 of 8 states that existing facilities applying for a
permit renewal shall annually update the stormwater plan. How much time is the NIEHS allotted in
order to update the existing plan, which was revised in June 2010?"
A: As the NIEHS updated the plan in June of 2010, an updated version should be completed for June of 2011.
Q: "The NIEHS would Iike to have the 27-acre NIEHS Lake incorporated into the receiving stream
name".
A: The NIEHS Lake is not a classified water body, therefore we cannot add this name as a receiving stream. The
receiving body must be designated as an Unnamed Tributary (UT) to Burdens' Creek.
Q: "The NIEHS was granted representative outfall status for the Building 108 outfall. We would like
to have the sample location designated as ROS instead of stormwater discharge outfall (SDO) in
Table 1..."
A: In an email from Bill Stienmetz dated April 24, 2009, Mr. Stienmetz stated "We have not been able to locate
the letter from NCDWQ that granted representative outfall status." The responsibility of showing representative
outfall status rests with the permittee. Additionally, ROS may be revoked if the process or discharges change, or if
DWQ otherwise deems appropriate. As the NIEHS was not able to locate a letter stating that they have obtained
it, please fill out and return the enclosed ROS farm to the DWQ Raleigh Regional Office, attn: Mack Wiggins.
The form can also be found on our website: littp.Ilportal.ncdenr.orgAveb/i oos/su/npdessw
The designation as SDO in the Analytical Monitoring Requirements is standard practice in DWQ SPU's permit
issuance and does not prevent permittees with ROS status from using that status. Additionally, using the "SDO"
notation allows DWQ to continue using the current version of the permit if outfall statuses change without a
permit modification (including the public notice process).

Q: The qualitative monitoring requirements have been changed and the stormwater visual evaluation
is now to be performed during a representative storm event in conjunction with analytical
monitoring. Does this mean that the qualitative monitoring must also occur with the first 30 minutes
of discharge? In addition, the NIEHS requests approval to continue performing the qualitative
monitoring at the representative outfall location only.
A: The intention of this permit language was that the qualitative monitoring should be done at the same time as
the analytical. Please monitor the discharge within ,the first 30 minutes.
Additionally, it is standard language in all of our general and individual permits that qualitative monitoring be-_
performed at each stormwater discharge outfall (SDO) regardless of representative outfaII status. Please continue
to monitor all of your outfalls for qualitative parameter regardless of ROS.
If you should have additional comments, please submit them to the Division of Water Quality
Stormwater Permitting Unit by July 30, 2010. .

Research Triangle Park, N.C. 27709
Webalts: www.niaho.nih.gov
Thank you for the opportunity to review the draft Stormwater permit. The NIEHS has reviewed the
permit and is providing comments in response to some of the limitations. The draft permit contains
Stormwater Pollution Prevention Plan conditions and analytical monitoring requirements that have been
strengthened. As such, the existing NIEHS plan must be revised to meet these requirements. The
compliance schedule in Part III, page I of 8 states that existing facilities applying for a permit renewal
shall annually update the stormwater plan. How much time is the NIEHS allotted in order to update the
existing plan, which was revised in June 2010?
The Certificate of Coverage designates the receiving stream "as a UT to Burden's Creek." The NIEHS
would like to have the 27-acre NIEHS Lake incorporated into the receiving stream name. For example,
the designation could be revised to "UT/NIEHS Lake to Burden's Creek" or ",UT to NIEHS Lake to
Burden's Creek." This would emphasize the proximity and downstream location of this water body with
regard to facility operations.
The NIEHS was granted representative outfall status (ROS) for the Building 108 outfall. We would like
to have the sample location designated as ROS instead of stormwater discharge outfall (SDO) in Table 1:
Analytical Monitoring Requirements and in the associated footnote. This would limit analytical
monitoring to the Building 108 outfall only.
The qualitative monitoring requirements have been changed and the stormwater visual evaluation is now
to be performed during a representative storm event in conjunction with analytical monitoring. Does this -
mean that the qualitative monitoring must also occur with the first 30 minutes of discharge? In addition,
the NIEHS requests approval to continue performing the qualitative monitoring at the representative
outfall location only.
Please let me know if you have any questions about our permit comments or if you would like additional
information about the NIEHS facility.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollutign Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
f`
l . Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to�contribute to contamination of
stormwater discharges. The site plan shall contain the.following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility_'s`location,in relation to transportation routes
and surface waters, the name of the receiving.water(s) to which the stormwater
outfall(s) discharges, or if the discharge is to a municipal separate storm sewer
system, the name of the municipality and the ultimate receiving waters, and
accurate latitude and longitude of thepoint(s) of discharge. The general location
map (or alternati Blythe site map) shall identify whether each receiving water is
impaired (on the state's303(d)`list of impaired waters) or is located in a
watershed for which'a TMDL has been established, and what the parameter(s)
of concern are. //
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: the site property
boundary, the stormwater discharge outfalls, all on -site and adjacent surface
waters and wetlands, industrial activity areas (including storage of materials,
disposal areas, process areas, loading and unloading areas, and haul roads), site
topography, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (3) previous years and any corrective actions taken to mitigate
spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
Part II Page 1 of 10

Permit No. NCS000360
B, Paragraph 5. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
2. Stormwater Management- Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, materialihandling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater managem en/ plan shall•d6cument the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Requirements and Re ords. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section ,
313 of Title III of the Superfun'd Amendments and Reauthorization Act (SARA)
water priority chemicals; and- storage -in any amount of hazardous substances; in.
order to prevent leaks and spills rfrom contaminating stormwater runoff. A table
or summary of all'sue"Manks nd stored materials and their associated secondary
containment areas,shall be•rnaintained. If the secondary containment devices are
connected to stormwater conveyance systems, the connection shall be controlled
by manually activated valves or other similar devices (which shall lie secured
closed with a�locking`mechanism), and any stormwater that accumulates in the
containment area -shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time.
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation- and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMA Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
Part II Page 2 of 10

Permit No. NCS000360
person shall be on -site at all times during facility operations that have the potential to
contaminate stormwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site.stormwater specific. • Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP,
but may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed. The program shall list
all stormwater control systems, stormwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,
material handling areas, disposal areas, process areasloadi
,ng and unloading areas, and
haul roads), all drainage features and structures; and --existing structural BMPs. The
program shall establish schedules of inspections, maintenance,,and housekeeping
activities of stormwater control systems, as well -as, facility, equipment, facility areas, and
facility systems that present a potential for stor'm water exposure or stormwater pollution.
Inspection of material handling areas and ,regular cleaning schedules of these areas shall
be incorporated into the program. Timely compliance with the established schedules for
inspections, maintenance, and housekeeping shall, recorded in writing and maintained
in the SPPP.
5. Employee Training. Trai'ning`programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response
and cleanup, preventative maintenance activities, and for any of the facility's operations
that have the potential to contaminate stormwater runoff. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be documented by.the signature of each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management • Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
Part 11 Page 3 of 10

Permit No. NCS000360
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part 1I1, Standard Conditions, Section B, Paragraph 5) to the Director that the changes
have been made.
8. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as
part of the Preventative Maintenance and Good Housekeeping Program at a minimum on
a semi-annual schedule, once during�the first half of the year (January to June), and once
during the second half (July to December), with at least 60 days separating' inspection
dates {unless performed more frequently than semi-annually). These facility inspections
are different from, and in addition to, the srormwater discharge characteristic monitoring
required in Part II B and C of this permit. "
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
shall include documentation of all monitoring, measurements,;inspections, maintenance
activities, and training provided to employees..including thelog of the sampling data and
of actions taken to implement BMPs associated with,the industrial activities, including
vehicle maintenance activities. Such documentation` shall be kept on -site for- a period of
five years and made available to the Direct eor,the;Director's authorized representative
immediately upon request. ,_f 1

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time
between this storm event and the previous storm event measuring greater than 0.1 inches must'be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.

This site discharges to the Jordan Lake Watershed which is penencing problems with nutrients
(Nitrogen and Phosphorus). A TMDL was approved for the,&,.Everett Jordan Reservoir in 2007
for a development strategy to control nutrients and meet the sta[e.c_hlorophyll a standard. The
Division will consider the monitoring results in determining whether additional BMPs are needed
to control the pollutant(s) of concern to the maximumextent�practicable.
If additional BMPs are needed to achieve the re" quired`level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a timetable
for incorporation of those BMPs into the'permitt`ed Stormwater Pollution Prevention Plan.
SECTION C: QUALITATIVE"MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified in Table 4, during the analytical
monitoring event. [If analytical monitoring is not required, the permittee still must conduct semi-
annual qualitative monitoring.] .Qualitative monitoring is for the purpose of evaluating the

Dear Mr. Stienmetz:
Dee Freeman
• Secretary
Subject: Draft NPDES Stormwater Permit
Permit No: NCS000360
National Institutes of Environmental Health Sciences
Durham County
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains. .
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
1. Analytical monitoring parameters have been added to this permit.
2. pH has been added to the analytical monitoring requirements. '
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part I1 Section B.- The permittee must also document the total precipitation for each event. If no discharge
occurs during the sampling period, the permittee must submit a monitoring report indicating "No Flow'
within 30 days of the end of the six-month sampling period. Additionally, samples must be taken a
minimum of 60 days apart, as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark
values require the permittee to increase monitoring, increase management actions, increase record'
keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered program. If the
sampling results are above a benchmark value, or outside of the benchmark range, for any parameter at
any outfall then the facility shall follow the Tier 1 guidelines which require a facility inspection within
two weeks and implementation of a mitigation plan within two months. If during the term of this permit,
the sampling results are above the benchmark values, or outside of the benchmark range, for any specific
parameter at a specific discharge outfall two times in a row (consecutive), then the facility shall foIIow the
Tier 2 guidelines which require a repetition of the steps listed for Tier 1 and also immediately institute
monthly monitoring for all parameters at every outfall where a sampling result exceeded the benchmark
value for two consecutive samples.
3. You are required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of
representative outfaIl status.
6. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)

8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. Monitoring for TPH has replaced Oil & Grease. This requirement appears in
all Individual Stormwater permits, however it only applies to facilities that do vehicle maintenance. If the
facility begins vehicle maintenance during the permitted timeframe then the requirements shall apply.
Other permit changes:
1. Additional guidance is provided about the Site Plan requirements. The site map must now ideritify,iftl,e
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants
in each outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past three years and also must certify that the outfalls have
been inspected to ensure that they do not contain non-stormwater discharges. Additional information is
provided in Part II Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part 11 Section A.
More details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II
Section A. The plan must also be updated annually to include a list of significant spiIIs and to certify that
the outfalls do not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial '
materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the
facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit
requirements. Additional information is provided in Part I Section A.
6. This site discharges to the Jordan Lake Watershed which is experiencing problems with nutrients
(Nitrogen and Phosphorus). 'A TMDL was approved for the B. Everett Jordan Reservoir in 2007 for a
development strategy to control nutrients and meet the state chlorophyll a standard. The Division will
consider the monitoring results in determining whether additional BMPs are needed to control the
pollutant(s) of concern to the maximum extent practicable. If additional BMPs are needed to achieve the
required level of control, the permittee will be required to (1) develop a strategy, for implementing
appropriate BMPs, and (2) submit a timetable for incorporation of those BMPs into the permitted
Stormwater Pollution Prevention Plan.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address Iisted at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] or

PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall,,be considered public information in accordance with Part III; Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
1. Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain t' e.following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility'�location in relation to .transportation routes
and surface waters, the name ofthe reeeiving.water(s) to which the stormwater
outfall(s) discharges, or if the discharge is to a municipal separate storm sewer
system, the name of the municipality and the ultimate receiving waters, and
accurate latitude and longitude of th,point(s) of discharge. The general location
map (or alternatively the site'map)1hall identify whether each receiving water is
impaired (on the state's 303(d)-1ist of impaired waters)'or is located in a
watershed for whieti a TMDL has been established, and what the parameter(s)
of concern are: //
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: the site property
boundary, the stormwater discharge outfalls, all on -site and adjacent surface
waters and wetlands, industrial activity areas (including storage of materials,
disposal areas, process areas, loading and unloading areas, and haul roads), site
topography, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area; buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at'the facility

B, Paragraph 5. The permittee shall rc-certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material'handling operations, and
manufacturing or fueling operations. Inareas„where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away 6io ,areas of potential contamination.
(b) Secondary Containment Requiremerits and Records. Secondary containment is
required for: bulk storage of liquid materials, storage in any amount of Section
3 l 3 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
Water priority chemicals; and storage.in{any amount of hazardous substances, in
order -to prevent leaks and`spills rfrom contaminating stormwater runoff. A table
or summary of ai'Nuch tanks and stored materials and their associated secondary
containment areas shall b�e;maintained. If the secondary containment devices are
:r connected to stormwatericonveyance systems, the connection shall be controlled
by rrianually activated valves or other similar devices (which shall be secured
closed with a,locking mechanism), and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible -for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
Part II Page 2 of t0

Permit No. NCS000360
person shall be on -site at all times during facility operations that have the potential to
contaminate stormwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) maybe a component of the SPRP,
but may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. . Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed. The program shall list
all stormwater control systems, stormwater discharge outfalls, all on -site and adjacent
' surface waters and wetlands, industrial activity areas (including material storage areas,
material handling areas, disposal areas, process areas,"Joading and unloading areas, and
haul roads), all drainage features and structures,'and existing structural BMPs. The
program shall establish schedules of inspections, maintenance,,and housekeeping
activities of stormwater control systems, as well as facility. equipment, facility areas, and
facility systems that present a potential for stormwater exposure or stormwater pollution.
Inspection of material handling areas and regular cleaning schedules of these areas shall
be incorporated into the program, Timely compliance with the established schedules for
ir
inspections, maintenance, and housekeep�✓ing s all"be recorded in writing and maintained
in the SPPP.
5. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response
and cleanup, preventative maintenance activities, and for any of the facility's operations
that have the potential to contaminate stor nwater runoff. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual✓training
shall be documented by,the`signature of each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the.
potential for the discharge of pollutants to surface waters. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 34 days of such notice, the permittee shall

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table I All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm evenihat measures greater than 0.1 inches of rainfall. The time
between this storm event and the previous storm, event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.

If: The first valid sampling results are above a benchmark value for outsi�of the benchmark range, for any
parameter at an outfall; _ \
Then: The permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving
sampling results.
2. Identify and evaluate possible causes of the benchmark value exceedence.
3. Identify potential and select the specifcl source"controls, operational controls, or physical
improvements to reduce concentrations oche parameters of concern, or to bring concentrations
within the benchmark range%`
4. Implement the selected actions within two months of the inspection.
5. Record each instance of atTier One response in the Stormwater Pollution Prevention Plan. Include
J
the date and value of the benchm' ark exceedence, the inspection date, the personnel conducting the
inspection, the selected actions, and the date the selected actions were implemented.
Tier Two
If: -During the term of this permit, the first valid sampling results from two consecutive monitoring periods
are above the benchmark values, or outside of the benchmark range, for any specific parameter at a
fie diseharize outfall:
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring for all parameters at every outfall where a sampling result
exceeded the benchmark value for two consecutive samples. Monthly (analytical and qualitative)
monitoring shall continue until three consecutive sample results are below the benchmark values or
within the benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow" to comply with reporting requirements.
4. Maintain a record of the Tier Two response in the Stormwater Pollution Prevention Plan.
Part II Page 7 of 10

During the term of this permit, if the valid sampling results required for the permit monitoring periods
exceed the benchmark value, or are outside the benchmark range, for any specific parameter at any specific
outfall on four occasions, the pennittee shall notify the DWQ Regional Office Supervisor in writing within
30 days of receipt of the fourth analytical results. DWQ may but is not limited to:
• require that the pennittee revise, increase, or decrease the monitoring frequency for the remainder
of the permit;
• require the permittee to install structural stornwater controls;
• require the pennittee to implement other stormwater control measures; or
• require that the permittee implement site modifications to qualify for the No Exposure Exclusion.
This site discharges to the Jordan Lake Watershed which is experiencing problems with nutrients
(Nitrogen and Phosphorus). A TMDL was approved for the B. Everett Jordan Reservoir in 2007
for a development strategy to control nutrients and meet the state chlorophyll a standard. The
Division will consider the monitoring results in determining whether additional BMPs are needed
to control the pollutant(s) of concern to the maximum extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (I ) develop a strategy for implementing appropriate BMPs, and (2) submit a timetable
for incorporation of those BMPs into the permitted Stornwater Pollution Prevention Plan,
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwatcr outfall regardless of
representative outfall status and shall be performed as specified in Table 4, during the analytical
monitoring event. [if analytical monitoring is not required, the permittee still must conduct semi-
annual qualitative monitoring.] Qualitative monitoring is for the purpose of evaluating the
effectiveness of the Stonnwater Pollution Prevention Plan (SPPP) and assessing new sources of
stormwater pollution.
In the event an atypical condition is noted at a stormwater discharge outfall, the pen-nittee shall
document the suspected cause of the condition and any actions taken in response to the
discovery. This documentation will be maintained with the SPPP.

This information is provided in response to questions that were generated during:your
stormwatcr inspc tlon for no exposure certification, which occurred on March 19, 2009.
TheNIEHS submitted an application for exclusion frorn permitting based on no exposure
of indtutdal materials and activities.
A stormwater permit �NCSOfl036U)-wr+sforigirially required for the NIEHS based on the
existence of an onsite waste handling facility (WYIF'). The WHF supports the NIEHS and
EPA, research missions and is regulated by NCDENR through a Hazardous Waste
Management permit (# NC27508900WR1).
The Waste Handling Facility (WHIM wad completed in 1998 and is used for receiving,
handling, packaging, and storing hazardous and radioactive wastes. 7'be'NHF was
expwided in 2001 to accommodate EPA needs for hamrdous waste management upon
ouupancy of its new facilities on the NIEI-1S / EPA campus. All waste is stored inside of
the secure, climate -controlled facility and no waste is stored outside. Facility security is
monitored by waste staff.,, perimeters electronic security systems, and by security patrol
inspecdons.
Waste is delivered into the facility approximately twice a day for sorting and packaging.
Waste arrives to the facility in small quantities (2.5 gallons or less) and is transferred
from the waste vehicle via'a chemical cart_ Outbound shipments of packaged waste for
disposal occur approximately 1.0 times per year. All drums/containers are managed using
industry best practices and handled with modern container handling equipment such as a
drum, dolly, band truck, etc- All containers are secured for transportation according to
manufacturer's specifications and DOT requirements,
The WHF is equipped with all necessary safety and environmental features for this type
of facility, including emergency showers, eye washes, spill containment dikes, grated
floors, segregated storage ar=, and a sloping loading dock pad designed with a trench
drain for contaitui:Jent in the event of spill at the loading dock.
All personnel handling waste at the facility receive training in contingency and spill
response planning. All personnel are trained annually in Hazardous Waste Operations and
Emergency lkesponso (HAZWOPER) for spill response and Incident Command System
(ICS) practices. The NIEITS and the EPA have also developed a eooredinated tirnergency
Response Plan for response to potential emergencies and releases at the facility.

counties and sixteen cities in the PTCOG region will be
impacted by these rules.
The Jordan Lake Rules will supersede existing rules for the
various water supply classes. Under this rule, the entire
Jordan Reservoir watershed, which encompasses the Haw
River sub basin and the New Hope sub basin, will be
designated as a critical water supply watershed, and

New Development: The Jordan Lake rules will impact how residential and commercial development
occurs in the watershed. Developers will incur significant costs under the requirements to increase controls
on pollutant loads to meet reduction goals. The requirements include limits on density and increased BMPs
installation, which will drive up the cost of homes and property, increase sprawl and possibly steer
development to other regions.
DWQ estimated costs to local government to meet requirements for stormwater retrofits on existing
development: $403,000,000.00 over five years. All local governments (cities and counties) in the
watershed will be required to install retrofit storm water controls on existing developed lands, Retrofit
programs must begin within four years of the effective date of the rule.
Additionally, local governments must exceed NPDES Phase II permit requirements to meet nutrient loading
reduction targets on new and existing development resulting in substantial cost increases beyond current
Phase II program costs. This places an undue financial burden on already limited municipal resources.
DWQ estimated costs to local governments located in the Haw River sub basin of the watershed for
Wastewater Treatment Plant upgrades to meet pollutant load reduction targets. $21 1,61 1,000.00
over ten years.

Background Information:
Jordan Reservoir is a multi -use impoundment operated by the U.S. Army Corps of Engineers. The reservoir
was formed with the construction of a dam on the Haw River in the Cape Fear River Basin. The lake covers
an area of 13,940 acres at elevation 216 feet msl (mean sea level), the normal operating level. The lake is
operated for flood control, water quality (low flow augmentation), fish and wildlife conservation,
recreation, and water supply. E i
Jordan Reservoir consists of two distinct arms - the Haw River and New Hope Creek arms. The Haw River
Arm of the lake has an average hydraulic retention time of five days and accounts for 70 to 90 percent of
the annual flow through Jordan Reservoir. The New Hope Creek Arm of the lake has an average hydraulic
retention time of 418 days. The Jordan Reservoir watershed encompasses 1,686 square miles and includes
parts of Alamance, Caswell, Chatham, Durham, Forsyth, Guilford, Orange, Randolph, Rockingham, and
Wake counties. It includes all or portions of the urban areas of Durham, Chapel Hill, Cary, Burlington,
Greensboro, and several other small municipalities.
The Jordan Lake/Haw River Watershed is considered a nutrient sensitive watershed (NSW). This means
Jordan Lake and its source waters are nutrient enriched causing algal blooms and taste and odor
problems in drinking water. The B. Everett Jordan Reservoir (Jordan Reservoir) Nutrient Management
Strategy and Total Maximum Daily Load (TMDL) was developed to satisfy state Nutrient Sensitive Water
(NSW) requirements and a federally -mandated TMDL. Both the NSW and TMDL programs include the
development of a calibrated nutrient response model to support a management strategy to control
nutrients and meet the state chlorophyll a standard.
The Clean Water Responsibility Act of 1997 (often referred to as House Bill 515) included legislation to
further address water quality problems in NSW waters (NC General Statute 143- 215.1(cl ) to (c5)). The
act set total nitrogen (TN) and total phosphorus (TP) NPDES permit limits for facilities discharging greater
than 0.5 MGD into the Jordan Reservoir/Haw River watershed. A 5-year compliance period for limits of
5.5 mg/L of TN and 2.0 mg/L of TP was established for qualifying wastewater facilities. The act provides
conditions for an extended compliance period, including the development of a calibrated nutrient response
model and the development of plans to optimize nutrient removal at the wastewater facility. The
municipalities of Greensboro, Mebane, Reidsville, Graham, Pittsboro, and Burlington, and the Orange
Water and Sewer Authority (OWASA) were granted a compliance extension in 1999. Facilities that did
not seek compliance are the City of Durham/Durham South wastewater treatment plant (WWTP) and the
Durham County/ Triangle WWTP. Conditions associated with the extended compliance period were
achieved and the calibrated nutrient response model was accepted by the Water Quality Committee
(WQC) of the Environmental Management Commission (EMC) in July 2002.

B. Everett Jordan Reservoir Phase 1 Nutrient TMDL — Final
Executive summary
The B. Everett Jordan Reservoir (Jordan Reservoir) Total Maximum Daily Load was developed to
satisfy state Nutrient Sensitive Water (NSW) requirements and a federally -mandated TMDL. Both
the NSW and TMDL programs include the development of a calibrated nutrient response model to
support a management strategy to control nutrients and meet the state chlorophyll a standard.
Jordan Reservoir is a multi -use impoundment operated by the U.S. Army Corps of Engineers. The
reservoir was fonned with the construction of a dam on the Haw River in the Cape Fear River
Basin, The lake covers an area of 13,940 acres at elevation 216 feet msl, the normal operating
level. The lake is operated for flood control, water quality (low flow augmentation), fish and
wildlife conservation, recreation, and water supply. Jordan Reservoir consists of two distinct arms
- the Haw River and New Hope Creek arms. The Haw River Arm of the lake has an average
hydraulic retention time of five days and accounts for 70 to 90 percent of the annual flow through
Jordan Reservoir. The New Hope Creek Arm of the lake has an average hydraulic retention time of
418 days. The Jordan Reservoir watershed encompasses 1,686 square miles and includes parts of
Alamance, Caswell, Chatham, Durham, Forsyth, Guilford, Orange, Randolph, Rockingham, and
Wake counties. It includes all or portions of the urban areas of Durham, Chapel Hill, Cary,
Burlington, Greensboro, and several other small municipalities.
The Clean Water Responsibility Act of 1997 (often referred to as House Bill 515) included
legislation to further address water duality problems in NSW waters (NC General Statute 143-
215.1(c 1) to (c5)). The act set total nitrogen (TN) and total phosphorus (TP) NPDES permit limits
for facilities discharging greater than 0.5 MGD into the Jordan Reservoir/Haw River watershed. A
5-year compliance period for limits of 5.5 mg/L of TN and 2.0 mg/L of TP was established for
qualifying wastewater facilities. The act also established that a calibrated nutrient response model
may be developed by DWQ in conjunction with affected parties, and the model may indicate the
required TN and TP concentration limits for dischargers greater than 0.5 MGD are different from
those listed above. In 1998, Senate Bill 1366 allowed the Environmental Management
Commission (EMC) to extend the compliance deadline for these dischargers if additional time was
needed to develop a calibrated nutrient response model. The municipalities of Greensboro,
Mebane, Reidsville, Graham, Pittsboro, and Burlington, and the Orange Water and Sewer
Authority (OWASA) were granted a compliance extension in 1999. Facilities that did not seek
compliance extensions were the City of Durham/Durham South W WTP and the Durham County/
Triangle WWTP. Conditions associated with the extended compliance period were achieved and
the calibrated nutrient response model was accepted by the Water Quality Committee (WQC) of
the EMC in July 2002.
The nutrient response model predicted a high frequency of violations of the chlorophyll a standard
in the management area representing the Upper New Hope Arm of Jordan Reservoir. This
management area corresponds to that portion of the lake upstream of SR 1008. As a result of this
model prediction, the Upper New Hope Arm of Jordan Reservoir was placed on the 2002 303(d)
List of impaired waters. The Lower New Hope Ann and the 1-law River Arm were later placed on
the 303(d) List of impaired waters in 2006 for chlorophyll a impairment. The Clean Water Act
(CWA) requires that a Total Maximum Daily Load (TMDL) be developed for each of the waters
appearing on the 303(d) list. The objective of a TMDL is to estimate the allowable pollutant loads

and allocate the loads to known sources so that the waterbody may be restored to its intended uses.
All TMDLs must be approved by the US Environmental Protection Agency (EPA). This document
represents Phase I of the Jordan Reservoir TMDL. The Haw River arm of the reservoir was listed
as impaired for elevated pH on the 2006 303(d) list of impaired waters. Phase II of this TMDL will
address the pH impairment of the Haw River arm. Like chlorophyll a, elevated pH is a symptom of
excessive nutrient loading to the lake.
Jordan Reservoir has historically been one of the most eutrophic reservoirs in North Carolina.
Excursions of the state water quality standard for chlorophyll a have been noted frequently,
especially in the Upper New Hope Arm. Nutrients from a variety of point and nonpoint sources
reach Jordan Reservoir. Point sources as a whole contributed an average of 1.5 million pounds of
nitrogen and 140 thousand pounds of phosphorus to the reservoir each year. Nonpoint sources
contributed an average of 2.5 million pounds of nitrogen and 350 thousand pounds of phosphorus
per year.
Through the combined efforts of the facilities that were granted the compliance extension and the
Division of Water Quality, multiple modeling tools were developed to evaluate conditions in the
reservoir and potential management strategies for the reservoir. This includes the development of a
calibrated hydrodynamic and nutrient response model for the years 1997 through 2001, an effluent
nutrient delivery model, a nutrient fate and transport model, and a watershed loading model. The
management strategies were determined through multiple runs of the nutrient response model with
a variety of reduction strategies for both total nitrogen and total phosphorus. For each run of the
nutrient response model, the frequency of violation of the chlorophyll a standard was evaluated for
the entire modeled period (1997 - 2001) and for critical conditions during the summer months.
Critical conditions were defined as May through September based on the model results and the
measured data. The two distinct arms of the lake, the Haw River and New Hope Creek arms, were
each evaluated separately. Further, the New Hope Creek arm was separated into the Upper New
Hope Arm and the Lower New Hope Arm. The split between these two areas is SR 1008.
Reduction targets were evaluated in temis of nitrogen and phosphorus loads. Multiple
combinations of nitrogen and phosphorus loading scenarios that resulted in an 8% standard
violation frequency were considered. Ultimately, three different targets were selected for Jordan
Reservoir corresponding to the different areas of the reservoir.

Upper New Hope Arm of Jordan Reservoir. All of the available loading was allocated to the
existing facilities. Therefore, there will be no new nitrogen or phosphorus bearing loads permitted
in this watershed. There are four facilities discharging greater than 100,000 gallons per day in the
watershed of the Upper New Hope Arm. These facilities account for 99.7% of the total permitted
flow from point sources. The discharge allocations for these four facilities provide equivalent
concentrations for each facility. For nitrogen, this equivalent concentration is 3.04 mg/L, and for
phosphorus this equivalent is 0.23 mg/L.
Haw River Arm of Jordan Reservoir. All of the available loading was allocated to the existing
facilities. Therefore, there will be no new nitrogen or phosphorus bearing loads permitted in this
watershed. There are ten facilities discharging greater than 100,000 gallons per day in watershed of
the Haw River Arm. These facilities account for 99.3% of the total pernlitted flow from point
sources. The discharge allocations for these ten facilities provide equivalent treatment levels for
each facility. For nitrogen, this equivalent treatment level is 5.3 mg/L, and for phosphorus this
equivalent is 0.67 mg/L
Nonpoint Source Strategy
The NPS management strategy proposed by DWQ staff builds on concepts implemented in the
Neuse and Tar -Pamlico River Basins. All of the following elements would apply in the
subwatersheds of both the Upper New Hope and Haw River arms, while only the riparian buffer
protection and new development controls - would apply in the Lower New Hope subwatershed.
The proposed strategy would require that:
• All agricultural operations would collectively meet N and P export performance goals as
implemented by local committees (EMC has no regulatory authority over this management
area);
• Stormwater:
o New development in unincorporated areas of all counties except Caswell and
Rockingham are subject to the post -construction stormwater measure of the NPDES
Phase lI requirements and are permitted by DWQ beginning July 1, 2007
o Seventeen of the twenty six municipalities in the watershed were issued pen -nits by
December 2005 to implement all six measures of the Phase H requirements, either
alone or as part of another MS4's permit, and were required to begin implementing
post -construction permitting under those permits by December 2007
o All local governments would achieve stormwater N and P export performance goals
from all new and existing development;
• DWQ would require local governments to protect riparian buffers;
• Persons who apply fertilizers to lands in the subwatershed would complete nutrient
management training and a written plan for those lands. A tax on fertilizer would fiend the
implementation of this rule;
• DWQ would work with DEH to develop programs to reduce N and P loading from on -site
wastewater (the EMC has no control over this management area);
• DWQ would refine existing wastewater land application permitting programs as needed;

follows:
(1) Stage 1 Adaptive Management Program to Control Nutrient Loading From
Existing Development. --
a. Municipalities and counties located in whole or in part in the Jordan
watershed shall implement a Stage 1 adaptive management program
to control nutrient loading from existing development in the Jordan
watershed. The Stage I adaptive management program shall meet the
requirements set out in A C.F.R. § 122.34 as applied by the
Department in the NPDES General Permit for municipal separate
storm sewer systems in effect on July 1, 2009. The Stage 1 adaptive
management program shall include all of the following measures:
1. A public education program to inform the public of the
impacts 'of nutrient loading and measures that can be
implemented to reduce nutrient loading from stormwater
runoff from existing development.
2. A mapping program that includes major components of the
municipal separate storm sewer system, including the location
of major outfalls, as defined in 40 Code of Federal
Regulations §122.26(b)(5) (July 1, 2008) and the names and
location of all waters of the United States that receive
discharges from those outfalls, land use types, and location of
sanitary sewers.
3. A program to identify and remove illegal discharges.
4. A program to identify opportunities for retrofits and other
projects to reduce nutrient loading from existing developed
lands.
5. A program to ensure maintenance of best management
practices implemented by the local government.
b. The Department shall accept local government implementation of
another stormwater program or programs meeting the standards set
out in this section as satisfying one or more of the requirements set
forth in sub -subdivision a. of this subdivision. The local government
shall provide technical information sufficient to demonstrate the
adequacy of the alternative program or program elements.
C. A Stage i adaptive management program to control nutrient loading
from existing development shall be implemented as follows:
1. No later than December 31, 2009, each local government
shall submit its Stage i adaptive management program to the
Commission for review and approval.
2. Within six months following submission of a Stage 1
adaptive management program, the Department shall
recommend that the Commission approve or disapprove the
program. The Commission shall either approve the program
or require changes based on the standards set out in
sub -subdivision a. of this subdivision. If the Commission
requires changes, the local government shall submit revisions
responding to the required changes within two months and
the Department shall provide follow-up recommendations to
the Commission within two months after receiving revisions.
Page 2 Session Law 2009-216 SL2009-0216

3. Within three months following Commission approval of a
Stage I adaptive management program, the local government
shall begin implementation of the program. Each local
government shall report annually to the Department on
implementation of its program.
(2) Stage 2 Adaptive Management Program to Control Nutrient Loading From
Existing Development. —
a. If the March 1, 2014 monitoring report or any subsequent monitoring
report for the Upper New Hope Creek Arm of Jordan Reservoir
required under Section 3(c) of this act shows that nutrient -related
water quality standards are not being achieved, a municipality or
county located in whole or in part in the subwatershed of that arm of
Jordan Reservoir shall develop and implement a Stage 2 adaptive
management program to control nutrient loading from existing
development within the subwatershed, as provided in this act. If the
March 1, 2017 monitoring report or any subsequent monitoring
report for the Haw River Arm or the Lower New Hope Creek Arm of
Jordan Reservoir required under Section 3(c) of this act shows that
nutrient -related water quality standards are not being achieved, a
municipality or county located in whole or in part in the
subwatershed of that arm of Jordan Reservoir shall develop and
implement a Stage 2 adaptive management program to control
nutrient loading from existing development within the subwatershed,
as provided in this act. The Department shall defer development and
implementation of Stage 2 adaptive management programs to control
nutrient loading from existing development required in a
subwatershed by this subdivision if it determines that additional
reductions in nutrient loading from existing development in that
subwatershed will not be necessary to achieve nutrient -related water
quality standards. In making this determination, the Department shall
consider the anticipated effect of measures implemented or scheduled
to be implemented to reduce nutrient loading from sources in the
subwatershed other than existing development. If any subsequent
monitoring report for an arm of Jordan Reservoir required under
Section 3(c) of this act shows that nutrient -related water quality
standards have not been achieved, the Department shall notify the
municipalities and counties located in whole or in part in the
subwatershed of that arm of Jordan Reservoir and the municipalities
and counties shall develop and implement a Stage 2 adaptive
management prograrn as provided in this subdivision.
b. The Department shall establish a load reduction goal for existing
development for each municipality and county required to implement
a Stage 2 adaptive management program to control nutrient loading
from existing development. The load reduction goal shall be
designed to achieve, relative to the baseline period 1997 through
2001, an eight percent (8%) reduction in nitrogen loading and a live
percent (5%) reduction in phosphorus loading reaching Jordan
Reservoir from existing developed lands within the police power
jurisdiction of the local government. The baseline load shall be
calculated by applying the Tar -Pamlico Nutrient Export Calculation
Workshect, Piedmont Version, dated October 2004, to acreages of
different types of existing development within the police power
jurisdiction of the local government during the baseline period. The
baseline load may also be calculated using an equivalent or more
accurate method acceptable to the Department and recommended by
the Scientific Advisory Board established pursuant to Section 4(a) of
this act. The baseline load for a municipality or county shall not
include nutrient loading from lands under State or federal control or
lands in agriculture or forestry. The load reduction goal shall be
SL2009-0216 Session Law 2009-216 Page 3

adjusted to account . for nutrient loading increases from lands
developed subsequent to the baseline period but prior to
implementation of new development stormwater programs.
C. Based on findings under sub -subdivision a. of this subdivision, the
Department shall notify the local governments in each subwatershed
that either:
1. Implementation of a Stage 2 adaptive management program
to control nutrient loading from existing development will be
necessary to achieve water quality standards in an arm of the
reservoir and direct the municipalities and counties in the
subwatershed to develop a load reduction program in
compliance with this section.
2. Implementation of a Stage 2 adaptive management program
to control nutrient loading from existing development is not
necessary at that time but will be reevaluated in three years
based on the most recent water quality monitoring
information.
d. A local government receiving notice of the requirement to develop
and implement a Stage 2 adaptive management program to control
nutrient loading from existing development under this section shall
not be required to submit a program if the local government
demonstrates that it has already achieved the reductions in nutrient
loadings required by sub -subdivision b. of this subdivision.
C. Within six months after receiving notice to develop and implement a
Stage 2 adaptive management program to control nutrient loading
from existing development, each local government shall submit to
the Commission a program that is designed to achieve the reductions
in nutrient loadings established by the Department pursuant to
sub -subdivision b. of this subdivision. A local government program
may include nutrient management strategies that are not included in
the model program developed pursuant to Section 3(e) of this act in
addition to or in place of any component of the model program. In
addition, a local government may satisfy the requirements of this
subdivision through reductions in nutrient loadings from other
sources in the same subwatershed to the extent those reductions go
beyond measures otherwise required by statute or rule. A local
government may also work with other local governments within the
same subwatershed to collectively meet the required reductions in
nutrient loadings from existing development within their combined
jurisdictions. Any credit for reductions achieved or obtained outside
of the police power jurisdiction of a local government shall be
adjusted based on transport factors established by the Department
document Nitrogen and Phosphorus Delivery from Small Watersheds
to Jordan Lake, dated June 30, 2001
f. Within six months following submission of a local government's
Stage 2 adaptive management program to control nutrient loading
from existing development, the• Department shall recommend that the
Commission approve or disapprove the program. The Commission
shall approve the program if it meets the requirements of this
subdivision, unless the Commission finds that the local government
can, through the implementation of reasonable and cost-effective
measures not included in the proposed program, meet the reductions
in nutrient loading established by the Department pursuant to
sub -subdivision b. of this subdivision by a date earlier than that
proposed by the local government. If the Commission finds that there
are additional or alternative reasonable and cost-effective measures,
the Commission may require the local government to modify its
proposed program to include such measures to achieve the required
reductions by the earlier date. if the Commission requires such
Page 4 Session Law 2009-216 SL2009-0216

modifications, the local government shall submit a modified program
within two months. The Department shall recommend that the
Commission approve or disapprove the modified program within
three months after receiving the local government's modified
program. In determining whether additional or alternative load
reduction measures are reasonable and cost effective, the
Commission shall consider factors including, but not limited to, the
increase in the per capita cost of a local government's stonwater
management program that would be required to implement such
measures and the cost per pound of nitrogen and phosphorus
removed by such measures. The Commission shall not require
additional or alternative measures that would require a local
government to:
I. Install or require installation of a new stormwater collection
system in an area of existing development unless the area is
being redeveloped.
2. Acquire developed private property.
31. Reduce or require the reduction of impervious surfaces within
an area of existing development unless the area is being
redeveloped.
g. Within three months after the Commission's approval of a Stage 2
adaptive management program to control nutrient loading from
existing development, the local government shall complete adoption
and begin implementation of its program.
h. Each local government implementing a Stage 2 adaptive
management program to control nutrient loading from existing
development shall submit an annual report to the Department
summarizing its activities in implementing its program.
i. If at any time the Department finds, based on water quality
monitoring, that an arm of the Jordan Reservoir has achieved
compliance with water quality standards, the Department shall notify
the local governments in the subwatershed. Subject to the approval of
the Commission, a local government may modify its Stage 2 adaptive
management program to control nutrient loading from existing
development to maintain only those measures necessary to prevent
increases in nutrient loading from existing development.
SECTION 3.(e) Model Stage 2 Adaptive Management Program to Control
Nutrient Loading From Existing Development. — No later than July 1, 2013, the Department
shall submit a model Stage 2 adaptive management program to control nutrient loading from
existing development to the Commission for approval. The model program shall identify
specific load reduction practices and programs and reduction credits associated with each
practice or program and shall provide that a local government may obtain additional or
alternative load -reduction credits based on site -specific monitoring data. In developing the
model program, the Department shall consider the findings and recommendations of the
Scientific Advisory Board established pursuant to Section 4(a) of this act and comments
submitted by municipalities and counties identified in 15A NCAC 02B .0262(7) (Jordan Water
Supply Nutrient Strategy: Purpose and Scope). The Commission shall review the model

Transportation roadway and nonroadway development shall be established
as provided in this subdivision. The load reduction goal shall be designed to
achieve, relative to the baseline period 1997 through 2001, an eight percent
(8%) reduction in nitrogen loading and a five percent (5%) reduction in
phosphorus loading reaching Jordan Reservoir from existing roadway and
nonroadway development in the Upper New Hope and Haw subwatersheds.
The load reduction goal for the Lower New Hope arm shall be designed to
maintain no increases in nitrogen and phosphorus loads from existing
roadway and nonroadway development relative to the baseline period 1997
through 2001. Load reduction goals for each subwatershed shall be
calculated from baseline loads for existing North Carolina Department of
Transportation development present during the baseline period. Baseline
loads shall be established for roadways and industrial facilities using
stormwater runoff nutrient load characterization data collected through the
National Pollutant Discharge Elimination System (NPDES) .Research
Program under NCS0000250 Permit Part 11 Section G. Baseline loads for
other nonroadway development shall be calculated by applying the
Tar -Pamlico Nutrient Export Calculation Worksheet, Piedmont Version,
dated October 2004, to acreages of nonroadway development under the
control of North Carolina Department of Transportation during the baseline
period. The baseline load for other nonroadway development may also be
calculated using an equivalent or more accurate method acceptable to the
Department and recommended by the Scientific Advisory Board established
pursuant to Section 4(a) of S.L. 2009-216. The load reduction goal shall be
adjusted to account for nutrient loading increases from existing roadway and
nonroadway development subsequent to the baseline period but prior to
implementation of new development stormwater programs pursuant to 15A
NCAC 02B .027 ] (4)(c).
(2) Sub -subdivision (b) of subdivision (3) and sub -subdivision (d) of
subdivision (4) of State and Federal Rule 15A NCAC 028 .0271 shall be
implemented as follows:
a. If' the March 1, 2014, monitoring report or any subsequent
monitoring report for the Upper New Hope Creek Arm of' Jordan
Reservoir required under Section 3(c) of S.L. 2009-216 shows that
nutrient -related water quality standards are not being achieved, State
and federal entities shall develop and implement a program to control
nutrient loading from existing development within the subwatershed,
as provided in this section and State and Federal Rule 15A NCAC
02B .0271. If' the March 1, 2017, monitoring report or any
subsequent monitoring report for the Haw River Arm or the Lower
New Hope Creek Arm of Jordan Reservoir required under Section
3(c) of S.L. 2009-216 shows that nutrient -related water quality
standards are not being achieved, State and federal entities shall
develop and implement a program to control nutrient loading from
existing development within the subwatershed, as provided in this
section and State and Federal Rule 15A NCAC 02B .0271. The
Department shall defer development and implementation of a
program to control nutrient loading from existing development
required in a subwatershed by this sub -subdivision if it determines
that additional reductions in nutrient loading from existing
development in that subwatershed will not be necessary to achieve
nutrient -related water quality standards. In making this
determination, the Department shall consider the anticipated effect of
measures implemented or scheduled to be implemented to reduce
nutrient loading from sources in the subwatershed other than existing
development. If any subsequent monitoring report for an arm of
Jordan Reservoir required under Section 3(c) of S.L. 2009-216 shows
that nutrient -related water quality standards have not been achieved,
SL2009-0484 . Session Law 2009-484 Page 5

b. If the Commission requires additional reductions in nutrient loading
from local governments pursuant to Section 3(f) of S.L. 2009-216,
the Commission shall require State and federal entities to modify
their nutrient reduction programs for the Upper New Hope Creek
subwatershed to achieve a total reduction in nitrogen loading from
existing roadway and nonroadway development in nitrogen loading
from existing development of thirty-five percent (35%) relative to the
baseline period 1997-2001.
(3) Notwithstanding sub -subdivision (d) of subdivision (4) of State and Federal
Rule 15A NCAC 02B .0271, the North Carolina Department of
Transportation may achieve the nutrient load reduction goal in subdivision
(1) of this section for existing roadway and nonroadway development under
its control by development of a load reduction program that addresses both
roadway and nonroadway development in the watershed for each ann of
Jordan Reservoir. A combined program to address roadway and nonroadway
development may include stormwater retrofits and other load -reducing
measures in the watershed including, but not limited to, illicit discharge
removal; street sweeping; source control activities such as pet waste
reduction and fertilizer management at NCDOT facilities; improvement of
existing stormwater structures; alternative stormwater practices such as use
of rain barrels and cisterns; stormwater capture and reuse; and purchase of
nutrient reduction credits. NCDOT may meet minimum implementation rate
and schedule requirements by implementing a combination of three
stormwater retrofits per year for existing roadway development in the Jordan
Lake watershed and other load -reducing measures identified in the program
to control nutrient loading from existing development developed pursuant to
State and Federal Entities Rule 15A NCAC 02B .0271 and this act and

4. A summary of the Best Management Practices utilized at the permitted facility. Summary
should consist of a short narrative description of each BMP's in place at the facility. If
the implementation of any BMP's is planned, please include information on these BMP's.
The NIEHS operates three oil/water separators that receive stormwater discharge from
aboveground fuel oil storage tank containment areas. All containment valves remain in the
closed position until collected stormwater can be visually evaluated for sheen and discoloration.
Stormwater releases occur weekly or as needed with records kept in a logbook. This logbook is
reviewed for completeness on a quarterly basis. In addition, all ASTs are equipped with locked
containment valves or locked fencing to limit access.
The representative outfall located at Building 108 discharges stormwater into a forested area,
which provides natural filtration before entering the NIEHS Lake. A small retention basin
located onsite retains roof drain discharges from both Building 105 and 106 to reduce stormwater
flow into an intermittent stream that feeds into the NIEHS Lake. An upcoming BMP involves
the placement of additional rip -rip at the end of several conveyance systems to reduce the flow of
stormwater entering the NIEHS Lake.
A high -hazard dam located onsite for stormwater control is maintained by the NIEHS. Water
held back by the dam creates a permanent 27 acre lake. Best management practices associated
with the dam include maintaining uniform vegetation cover, removing trees to avoid root
damage, and semiannual mowing to control overgrowth and vegetation type. The NIEHS has
contacted the NC Division of Land Resources and requested an official inspection of the dam to
review structural safety and operational compliance.
The NIEHS provides annual RCRA contingency, SPCC and stormwater management training for
all waste specialists, oil handling personnel and employees involved with facility operations,
maintenance and repairs. Annual drills.are also conducted to evaluate spill response plans,
cleanup procedures and preventative maintenance activities.
A short narrative describing any significant changes in industrial activities at the
permitted facility. Significant changes could include the addition or deletion of work
processes, changes in material handling practices, changes in material storage practices,
and/or changes in the raw materials used by the facility.
Significant changes in NIEHS raw material storage practices include the installation of a 2000
gallon capacity E85 storage tank, a 4000 gallon fuel oil storage tank, and a 1250 gallon
emergency generator day tank. The E85 aboveground storage tank and associated fuel
dispensing station was installed to provide alternative fuel (85% ethanol / 15% gasoline) for the
NIEHS fleet vehicles in accordance with Executive Order 13148. The NIEHS uses about 100
gallons of E85 per week and receives a 1500 gallon delivery of E85 about once per calendar
quarter. This storage tank is double -walled and includes an overfill alarm and containments
around the pump and the fill hatch. The new fuel oil storage tank and generator day tank were
installed to support emergency power generation for a portion of the NIEHS campus. Both of
these tanks are double -walled with the larger tank connected in series with the smaller day tank.
The aboveground piping between the two tanks is also double -walled.

The NIEHS operates a chemical waste treatment, storage, and disposal facility in Building 108.
The loading dock area associated with this building is equipped with a trench drain for
containment of spills that could occur during chemical deliveries. The parking lot in front of the
building is graded to draw water away from the structure and minimize the potential volume of
stormwater that could enter the trench drain system following a spill. The trench drain valve
remains closed with collected rainwater visually evaluated for the presence of sheen and
discoloration before being released to the environment. Before 2006, the trench drain valve
remained open at all times and was closed only for maintenance and in the event of a spill. The
trench drain valve was replaced in 2006 to improve access and allow for rapid closure. The
previous valve had been located below grade and required multiple revolutions for complete
closure.

Dear Mr. Wiggins:

P.O. Box 12233
Research Triangle park, N.C. 27709
Website: www.niehe.nlh.gov
This information is provided in response to questions that were generated during your
stormwater inspection for no exposure certification, which occurred on March 19, 2009.
The NIEHS submitted an application for exclusion from permitting based on no exposure
of industrial materials and activities.
A stormwater permit (NCS000360) was originally required for the NIMIS based on the
existence of an onsite waste handling facility (WTIF). The WHF supports the NIEHS and
EPA.. research missions and is regulated by NCDENR through a Hazardous Waste
Management permit (# NC2750890004-R1).
The Waste Handling Facility (WHF) was completed in 1998 and is used for receiving,
handling, packaging, and storing hazardous and radioactive wastes. The WHF was
expanded in 2001 to accommodate EPA needs for hazardous waste management upon
occupancy of its new facilities on the NIE14S / EPA campus. All waste is stored inside of
the secure, climate -controlled facility and no waste is stored outside. Facility security is
monitored by waste staff., perimeter electronic security systems, and by security patrol
inspections.
Waste is delivered into the ,facility approximately twice a day for sorting and packaging.
Waste arrives to the facility in small quantities (2.5 gallons or less) and is transferred
from the waste vehicle via a chemical cart. Outbound shipments of packaged waste for
disposal occur approximately 10 times per year. All drums/containers are managed using
industry best practices and handled with modern container handling equipment such as a
drum dolly, hand truck, etc_ All containers are secured for transportation according to
manufacturer's specifications and DOT requirements.
The V79F is equipped with all necessary safety and environmental features for this type
of facility, including emergency showers, eye washes, spill containment dikes, grated
floors, segregated storage areas, and a sloping loading'dock pad designed with a trench
drain for containment in the event of spill at the loading dock.
All personnel handling waste at. the facility receive training in contingency and spill
response planning. All personnel are trained annually in Hazardous Waste Operations and
Emergency Response (HAZ WOPER) for spill response and Incident Command System

During an excavation of out -of -service USTs, an in-service tank ruptured releasing an
estimated 1600 gallons of #2 fuel oil. No material entered the lake. The spill was cleaned up
through soil removal. Groundwater -monitoring wells indicated effective removal of
contaminated soil.
10/19/1990
Bldg. 101 Fuel Tank
An estimated 100-150 gallons of #2 fuel oil was released through an emergency generator
day tank vent pipe. A portion of this material passed through the storm sewer system and
entered the lake. Booms and mats were used to absorb the spilled material on the lake.
04/11A997
Bldg. 105 Fuel Tanks
Tanker truck released approximately 10 gallons of fuel oil when disconnecting lines. Spill
mats were used to clean up the spill, which was confined to pavement in the immediate area.

A sanitary sewer overflow due to a partially obstructed sewer line occurred at the NIEHS on February 7,
2007 between the hours of 10:15 AM and 3:30 PM_ Wastewater discharged at an estimated 5 gallons per
minute onto a grassy area on the NIEHS Campus resulting in a total spill volume of about 1500 gallons.
A portion of the discharge traveled across the grassy area for about 500 feet before entering into a. small
intermittent stream that feeds into the NIEHS Lake. A small portion of the total spill volume may have
entered the NIRRS Lake. The overflow discharge from the manhole was clear which indicates that the
primary constituents were likely cooling tower water and treated scrubber effluent. No discoloration or
sheen was observed on the NIFHS Lake or the affected tributary. The NC Division of Water Quality was
notified via voicern ai I message left on your office phone within one hour after the spill was discovered.
Service was :requested froEn an offsite plumbing contractor, Brown Brothers Plumbing & Heating, lnc.,
within one hour after the overflow was first noticed. Attempts were made to reduce wastewater flow
from the utility operations by retaining water in the cooling towers while awaiting arrival of the plumbing
contractors. Brown Brothers arrived at the site of the overflow about 3:00 PM and finished clearing the
sewer line at about 3:40 PM. A small amount of paper towels, which may have contributed to the
obstruction and subsequent overflow, were found in the line.
The NIEHS landscaping contractors applied 350 pounds of hydrated lime to the impacted areas about
10:30 AM on February 8, 2007. Only a small amount of solid residue was apparent in the spill area near
the miiuihole. This residue: received a second application of hydrated lime to assure disinfection. The lake
surface and shoreline were examined to determine whether aquatic life had been impacted by the sewer
overflow. There were no dead fish observed during these surveys which were conducted at 3:00 PM on
February 7, 2007 and at 11:00 AM on February 8, 2007.
The NIEHS plans to closely monitor wastewater levels at this location over the next few weeks to
evaluate whether there are indications of a redeveloping obstruction. The NIEHS also plans to distribute
educational information to all employees via email and an electronic newsletter in an effort to reduce the
potential for inappropriate disposal of materials and future sewer overflows. In addition, a small amount
of soil is to be removed from several muddy areas located downstream from the sewer overflow as per
your request received during today's site visit. A Sanitary Sewer Overflow Reporting Form is attached to
this letter. Please let me know if you require any additional information concerning this incident.

Subject: NPDES Stormwater Permit Renewal
National Institute Of Env Health Science
Permit Number NCS000360
Durham County
Dear Permittee:
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000360. This permit expires
on April 30, 2007. North Carolina Administrative Code (15A NCAC 2H.0105(e)) requires that an application for
permit renewal be filed at least 180 days prior to expiration of the current permit. In order to assure your continued
coverage under your permit, you must apply to the Division of Water Quality (DWQ) for renewal of your permit.
To make this renewal process easier, we are informing you in advance that your permit will be expiring. Enclosed
you will find an individual permit renewal application form, supplemental information request, and Stormwater
Pollution Prevention Plan certification.
Filing the application form along with the requested supplemental information will constitute your application for
renewal of your permit. As stated above, the application form must be completed and returned along with all
requested information by May 4, 2007 in order for the permit to be renewed by April 30, 2007.
Failure to request renewal by May 4, 2007 may result in a civil assessment of at least $500.00. Larger penalties
may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility without
coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and could
result in assessments of civil penalties of up to $25,000 per day,
If you have any questions regarding the permit renewal procedures please contact Mike Randall of the Stormwater
Permitting Unit at [phone], ext. 545.

Sanitary Sewer Overflow at NIEHS, RTP
Durham County
On February 8, 2007 staff from the Division of Water Quality staff conducted a site visit to National Institute of
Environmental Health Sciences in response to a sanitary sewer overflow. Your cooperation. at the site was greatly
appreciated. As a result of the site investigation, NIESH are required to comply with the following immediately:
1. Remove no more than two inches deep of soil from the settled pockets of sewage down hill from the manhole.
The distance of removal must be at least 50 feet towards the lake or up to the marked area during the site
visit.
2. Distribute educational material to all employees explaining what not to put down the drain to prevent future
sewer blockage.
Compliance with the above items must be achieved by March 23, 2007. Failure to comply will result to a Notice
of Violation and possibly a fine. If you have any questions concerning this, please contact me at telephone number
919/791-4200.

A sanitary sewer overflow due to a partially obstructed sewer line occurred at the NIEHS on February 7,
2007 between the hours of 10:45 AM and 3:30 PM. Wastewater discharged at an estimated 5 gallons per
minute onto a grassy area on the NIEHS Campus resulting in a total spill volume of about 1500 gallons.
A portion of the discharge traveled across the grassy area for about 500 feet before entering into a small
intermittent stream that feeds into the NIEHS Lake. A small portion of the total spill volume may have
entered the NIEHS Lake. The overflow discharge from the manhole was clear which indicates that the
primary constituents were likely cooling tower water and treated scrubber effluent. No discoloration or
sheen was observed on the NIEHS Lake or the affected tributary. The NC Division of Water Quality was
notified via voicemail message left on your office phone within one hour after the spill was discovered.
Service was requested from an offsite plumbing contractor, Brown Brothers Plumbing & Heating, Inc.,
within one hour after the overflow was first noticed. Attempts were made to reduce wastewater flow
from the utility operations by retaining water in the cooling towers while awaiting arrival of the plumbing
contractors. Brown Brothers arrived at the site of the overflow about 3:00 PM and finished clearing the
sewer line at about 3:40 PM. A small amount of paper towels, which may have contributed to the
obstruction and subsequent overflow, were found in the line.
The NIEHS landscaping contractors applied 350 pounds of hydrated lime to the impacted areas about
10:30 AM on February 8, 2007. Only a small amount of solid residue was apparent in the spill area near
the manhole. This residue received a second application of hydrated lime to assure disinfection. The lake
surface and shoreline were examined to determine whether aquatic life had been impacted by the sewer
overflow. There were no dead fish observed during these surveys which were conducted at 3:00 PM on
February 7, 2007 and at 11:00 AM on February 8, 2007.
The-NIEHS plans to closely monitor wastewater levels at this location over the next few weeks to
evaluate whether there are indications of a redeveloping obstruction. The NIEHS also plans to distribute
educational information to all employees via email and an electronic newsletter in an effort to reduce the
potential for inappropriate disposal of materials and future sewer overflows. In addition, a small amount
of soil is to be removed from several muddy areas located downstream from the sewer overflow as per
your request received during today's site visit. A Sanitary Sewer Overflow Reporting Form is attached to
this letter. Please let me know if you require any additional information concerning this incident.

Sanitary Sewer Overflow on the NIEHS Campus
Investigation of this incident indicates that inappropriate materials may have contributed to a sewer line
blockage resulting in a minor overflow. The sanitary sewer system is designed for disposal of used
water, human body waste, and toilet paper. Please remember that trash receptacles are provided in our
restrooms and break areas for the disposal of solid waste materials such as paper towels, food scraps,
and clothing. These items should not be flushed down the toilet or allowed to otherwise enter the sewer
system.
Wastewater discharged into the sanitary sewer system by the NIEHS is treated offsite at the Triangle
Wastewater Treatment Plant, which is located near the intersection of T.W. Alexander Drive and NC
Highway 55. Small scale pretreatment units operated onsite by the NIEHS include silver recovery units
in the photo development labs and grease separation systems in the cafeteria. Our wastewater permit
contains effluent limits for mercury, oil & grease, pH, and temperature along with monitoring
requirements for numerous other pollutants. The NIEHS'discharged 46 million gallons of wastewater
into the Durham County sanitary sewer system during calendar year 2006.

Dear Mr. Steinmetz:
In response to your renewal application for continued coverage under NPDES stormwater permit
NCS000360, the Division of Water Quality (Division) is forwarding herewith the subject state - NPDES
permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215 .1
and the Memorandum of Agreement between North Carolina and the US Environmental Protection
agency dated May 9, 1994 (or as subsequently amended).
Please note that the Division has revised the analytical monitoring strategy for individual
stormwater permits. Based on a review of the permit monitoring data received to date, the analytical
monitoring measurement frequencies have been changed and cut-off concentrations have been removed.
These changes will be implemented for all second term individual stormwater permits with analytical
monitoring requirements. For those permits with analytical monitoring requirements, Part 13 -
Monitoring, Controls, and Limitations for Permitted Discharges has been modified to reflect the change
in monitoring strategy.
The qualitative monitoring strategy remains the same as the first term of the permit. Please note
that the semi-annual qualitative monitoring is a requirement of the permit. Failure to complete the
monitoring as required is a violation of the permit and any permit noncompliance constitutes a violation
of the Clean Water Act. Reference Part 111, Section A, Item 2 "Duty to Comply", Item 9 "Penalties for
Tampering " and Item 10 "Penalties for Falsification of Reports" of your permit for further information.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30)
days following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative
Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611 -7447. Unless such demand is
made, this decision shall be final and binding.
Please take notice this permit is not transferable. Part lll, B.2. addresses the requirements to be
followed in case of change in ownership or control of this discharge.

Dear Mr. Steinmetz:
In response to your renewal application for continued coverage under NPDES stormwater permit
NCS000360, the Division of Water Quality (Division) is forwarding herewith the subject state - NPDES
permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215 A
and the Memorandum of Agreement between North Carolina and the US Environmental Protection
agency dated May 9, 1994 (or as subsequently amended).
Please note that the Division has revised the analytical monitoring strategy for individual
stormwater permits. Based on a review of the permit monitoring data received to date, the analytical
monitoring measurement frequencies have been changed and cut-off concentrations have been removed.
These changes will be implemented for all second term individual stormwater permits with analytical
monitoring requirements. For those permits with analytical monitoring requirements, Part IT -
Monitoring, Controls, and Limitations for Permitted Discharges has been modified to reflect the change
in monitoring strategy.
The qualitative monitoring strategy remains the same as the first term of the permit. Please note
that the semi-annual qualitative monitoring is a requirement of the permit. Failure to complete the
monitoring as required is a violation of the permit and any permit noncompliance constitutes a violation
of the Clean Water Act. Reference Part IH, Section A, Item 2 "Duty to Comply", item 9 "Penalties for
Tampering " and Item 10 "Penalties for Falsification of Reports" of your permit for further information.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30)
days following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative
Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611 -7447. Unless such demand is
made, this decision shall be final and binding.
Please take notice this permit is not transferable. Part [ll, B.2. addresses the requirements to be
followed in case of change in ownership or control of this discharge_

Dear Ms. Lau:
Piease be advised that the containment area for the two 120,000 gallon #2 fuel oil storage
tanks has been connected to the existing oil/water separator which previously served the
underground storage tanks prior to their removal. As a result, the NIEHS currently
operates three oil water separators on facility property. This additional oil water
separator will be documented in the 2001 Stormwater Pollution Prevention Plan
amendments and during the upcoming permit.renewal process.
A potential change in the character of the existing stormwater discharge outfall
monitoring point was discussed with you via this morning's telephone conversation. This
change involves the introduction of additional paved surface area runoff into the
stormwater drainage system prior to the outfall. As per your recommendation, the 2001
Stormwater Pollution Prevention Plan will also be updated to reflect this change.
Please contact me at [phone] if you have any questions concerning this matter.

Subject: NPDES Stormwater Permit Renewal
Nat Inst Of Env Health Science
Permit Number NCS000360
Durham County
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000360. This permit expires
on June 30, 2002. North Carolina Administrative Coe (15A NCAC 2H.0105(e)) requires that an application for
permit renewal be filed at least 180 days prior to expiration of the current permit. In order to assure your continued
coverage under your permit, you must apply to the Division of Water Quality (DWQ) for renewal of your permit.
To make this renewal process easier, we are informing you in advance that.your permit will be expiring. Enclosed
you will find an individual permit renewal application form, supplemental information request, and Stormwater
Pollution Prevention Plan certification.
Filing the application form along with the requested supplimental information will constitute your application for
renewal of your permit. The application form must be completed and returned along with all requested information
by January 15, 2002 in order to constitute a timely renewal filing.
Failure to request renewal by January 15, 2001 may result in a civil assessment of at least $500.00. Larger
penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility
without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $25,000 per day.
If you have any questions regarding the permit renewal procedures please contact Aisha Lau of the Stormwater and
General Permits Unit at [phone], ext. 578.

Pursuant to Permit No. NCS000360, the NIEHS is submitting a report which
includes data pertaining to stormwater sampling/analyses. This report
refers to one stormwater sample taken on November 2, 1999 from an
outfall adjacent to Building 108 (chemical storage building). Included
are the following in this packet:
1) Chemical & Environmental Technology, Inc. analytic report
2) Chain of Custody form
3) Data logger speadsheet depicting precipitation data
There are some changes that have occurred at the NIEHS that impact our
stormwater program. First, the NIEHS officially closed down its
hazardous waste treatment operation in Building 106 (incinerator
building) on October 29, 1999. Outfall #1 had been established to
sample stormwater related to this building. Since-Building_10.6-is-no

Secondly, Building 108 has been completed and is the new chemical
storage building. The old chemical storage:building,=(-Bui3ding_10:3_)=will

As you will note in the report, the COD reading for this sample was 49
mg/l, below the 120 mg/l threshold. The aluminum level registered at
6.17 mg/l, higher than the threshold of .375 mg/l . Wei=`heave-no en

measured by a Cole -Palmer portable pH meter. The lab measurement for pH
was 7.79 but the sample was out of 15 minute holding time.
