Subject: Draft NPDES Stormwater Permit
Permit No. NCS000087
Pentair Pool Products Inc.
Lee County
Dear Mr. Giardina:
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. TSS will remain in the analytical monitoring requirements
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. You must also document the total precipitation for each event. If no
discharge occurs during the sampling period, you 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 follow the Tier 2 guidelines which
require a repetition of the steps listed for Tier I 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 II 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
and event duration parameters are in this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with
analytical and qualitative monitoring.

Other proposed_ changes:
1. 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 outfali. The map requirements are stated more explicitly.
Arid, 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 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-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.
Please submit any comments to me no Iater 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.

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, an oil 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 with the SPRP may be incorporated by reference into the
SPRP.�i�
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'regutar cleaning schedules of

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

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, an oil 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 with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Housekeeping •P ograin: A preventative
maintenance program shall be developed. The, program shall document'schedules of
inspections and maintenance activities of stormwater control systems, plant equipment

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
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.

measurement of flow at 20 minute intervals during the rainfall event.
32. Total Maximum Daily Load (TMDL)
A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet
water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL is a detailed
'water quality assessment that provides the scientific foundation for an implementation plan. The
implementation plan outlines the steps necessary to reduce pollutant loads in a certain body of water to
restore and maintain water quality standards in all seasons. TheCleanWater Act, section 303, establishes
the water quality standards and TMDL programs.
33. Toxic Pollutant
Any pollutant listed as toxic under Section 307(a)(1),of the Clemater Act.

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000087
Pentair Pool Products Inc.
Lee County
Dear Mr. Giardina:
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. TSS will remain in the analytical monitoring requirements
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. You must also document the total precipitation for each event. If no
discharge occurs during the sampling period, you 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 instaII 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 II Section B. Qualitative monitoring is required
regardless of representative outfaII 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
and event duration parameters are in this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with
analytical and qualitative monitoring.

Permit No. NCS000087
Other proposed changes:
1. 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 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 11 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 PoIIution Prevention Plan have been specified in
Part 11 Section A. The plan must also be updated annuaIIy 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.
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 Iikely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] x 360 or

Revised Permit Recommendations: Analytical Monitoring:
1. TSS sampling will stay in the 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
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 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. The permittee 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.
6. The permittee is 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.
Other Proposed Changes to the Previous Permit:
1. 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 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 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-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.
1. 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

Compliance Evaluation Inspection
Pentair Pool Products Inc.
NPDES Permit No: NCS000087
Lee County
Dear Mr. Giardina:
On January 24, 2008, I, Vicki Webb, of the Raleigh Regional Office conducted a compliance
evaluation inspection of the subject facility. David June and yourself represented the facility
during the inspection. All of the help was appreciated as it eased the inspection process.
The following observations were made:
1. The Pentair Pool Products Inc. is permitted to discharge stormwater into the receiving
waters designated as Little Buffalo Creek, classified WS IV waters in the Cape Fear
River Basin.
2. Facility stormwater records were reviewed during the inspection. The Site plan, the storm
water management plan, and the spill prevention and response plan were presented and
appeared complete.
3. Qualitative and quantitative inspection records were available for review and appeared
complete.
4. The facility contains four stormwater outfalls. All four of the facility's stormwater
outfalls were observed during the inspection. I recommend that the facility maintain the
outfalls. Outfall A was hard to see due to small trees and brush growing around and over
hanging the outfall.
5. Analytical monitoring requirements for this facility are NOT being met. The facility
could not produce any evidence of samples being taken at any of the four outfalls on site.
This is a direct violation of your permit. I recommend that the facility review their permit
on Analytical Monitoring Requirements, Part II, Section B of the NPDES permit. �

Subject: NPDES Permit Renewal Application
Pentair Pool Products Inc.

Individual Stormwater Permit
Lee County .
Dear Mr. Schubert:
The Division of Water Quality's Stormwater Permitting Unit (SPU) acknowledges receipt of
your renewal application for coverage under NPDES Permit Number NCS000087 on May 28, 2004.
We apologize for the Iengthy delay in responding to your submittal and are now making every effort to
review your permit renewal as expeditiously as possible. Our Unit anticipates making significant
progress on individual permits over the next six months to reduce our backlog.
. We are currently beginning our review of your renewal application. Please continue to comply
with,all conditions and monitoring requirements in your expired NPDES stormwater permit. As
long as you have submitted a complete renewal request package and maintain compliance with those
permit conditions, stormwater discharges from this facility are authorized by that permit until the
Division issues a renewal permit or notifies you of an alternative action.
In your renewal package you stated that analytical monitoring had not ,been done during the last
permit term, so it would be performed in 2005. Please submit to me a copy of these monitoring results
for use in my review of the permit renewal. Please notify us if any significant changes have taken place
at this facility since you submitted the renewal package. If you have any questions about this matter,
please contact me at [phone], extension 360.

RE: Stormwater Permit No. NCS000087 Renewal
Pentair Pool Products, Inc.
1620 Hawkins Ave.
Sanford NC 27330 Tel. [phone] / Fax [phone]
The following supplemental information require for renewal of the Individual NPDES
Stormwater Permit is provided:
1. Current Site MgR is attached. There have been no significant changes to this facility's
industrial activity locations. A new covered loading dock has been added to the east side
of Building 2 Warehouse and gravel trailer parking has been added around the south side
of Building 3 Tank Plant, and the east sides of Building 2 Warehouse and Building 1
Manufacturing/ Assembly Plant. These additions are shown on the attached Site Map.
The attached site map has been reduced in size. The full-size original is available for
review at the Permittee's facility.
2. Summary of Analytical Monitoring. This Permittee did not conduct analytical
monitoring during the current permit term. This Permittee did not realize that analytical
monitoring was required. As stated in the May 24, 1999 permit renewal letter,
monitoring was not required during the 1994-1999 permit term. When the 1999-2004
permit was received, this Permittee apparently did not realize the change in monitoring
requirements was actually an expansion to include sample collection and analysis.
During a site visit in late 2002 by Ricky Revels of the Fayetteville Regional Office, there
was no indication that any required tasks were not being performed according to the
permit. All permit and SWPPP documents, including visual observation reports, were
reviewed at that time; Mr. Revels seemed satisfied with Pentair Pool's performance.
In April 2004, this Permittee consulted with Stormwater Services Group on providing
assistance with this permit renewal letter. Only at that time did Pentair Pool Products
realize that quarterly sample collection and analysis was required.

Mr. William Schubert of Pentair Pool Products attempted to collect a sample on May 1,
2004, but off -site construction associated with the US 421 By-pass project caused an
excessive amount of sediment to flow into this Permittee's sample outfall — no samples
were collected'.
Pentair Pool Products has contracted with Stormwater Services Group to collect quarterly
samples if in-house staff are not available during representative storm events. This
Permittee will make every reasonable attempt to collect four quarterly samples over the
next twelve months. Sample results will be submitted to NCDWQ as soon as laboratory
reports are received.
3. Summary of Visual Monitoring. This Permittee conducted semi-annual visual
monitoring of the outfalls. The results are summarized on forms provided in Attachment
2. No significant problems were observed except with color, clarity, and suspended
solids as noted on May 1, 2004.
4. Summary of Best Management Practices. The following BMPs have been implemented,
or are an on -going practice:
• Good Housekeeping
a. Weekly litter patrol is performed by janitorial staff.
b. Well -organized storage rooms are maintained.
c. Clean production areas are maintained
d. Proper disposal of solid waste into closed -topped dumpsters is practiced.
• Preventative Maintenance
a. Scheduled maintenance of production equipment.
b. Routine inspections of tanks, totes, and drums.
c. Inspection and repair of drainage ditches as needed.
• Spill Prevention and Response
a. Employees are trained for spill prevention and response according to the
chemicals they handle.
b. Spill kits are provided in production areas.
c. Some employees are trained to the 40-hour OSHA Hazwoper level.
• Containment for Pit for accidental spills
a. A covered concrete pit is provided to contain spills from interior ASTs.
• Proper hazmat storage
a. Drums containing hazmats are stored within covered secondary containment.
b. Storage area is inspected daily for potential problems.
c. Chemical inventory is minimized.
• Chemicals collected for recycling
a. Waste resin is allowed to harden in containers, rendering it an inert and
landfill -acceptable material.
b. Acetone is collected for off -site reclamation.
1 The storm on May 1, 2004 was not typical — over 4 inches of rain fell in the vicinity of Pentair Pool Products,
causing some erosion control devices at the adjacent highway project to fail.

• Use of recycled chemicals where feasible
a. Re-claimed acetone is purchased when available.
* Replace solvent -based paint with water -based paint
• Vegetated Buffer around property perimeter
a. Natural pine and hardwood buffer is maintained around property.
b. Significant sheet flow is diverted through vegetated buffer.
c. Permittee plans to re -stabilize drainage ditches with either grass or riprap
lining where appropriate.
d. Slopes adjacent to new gravel parking areas will be planted with grass and
mulched.
5. Significant Changes to Industrial Activities.
• Addition or deletion of work processes - none.
• Changes in Material Handling practices —
a. Used wood pallets are picked up by a vendor for re -use or fuel.
b. Cardboard compacted on -site prior to pick-up by a vendor for recycling.
• Changes in Material Storage practices — none.
• Changes in Raw Materials ---
a. This Permittee has joined a cooperative that recycles acetone and resin. One
hundred percent (100%) reclaimed acetone is purchased when the supply
source can accommodate the order.
6. Certification of SWPPP. See Attachment 3.
The above narrative summarizes our permit compliance over the last five-year permit term.
Please do not hesitate to call if you have any questions.
Sincerely,
Pentair Pool Products, Inc.

Subject: NPDES Stormwater Permit Renewal
Pentair Pool Products Inc
Permit Number NCS000087
Lee County
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000087. This permit expires
on November 30, 2004. 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 arc 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 June 3, 2004 in order for the permit to be renewed by November 30, 2004.
Failure to request renewal by June 3, 2004 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 Bill Mills of the Stormwater and
General Permits Unit at [phone], ext. 548.

Dear Permittee:
Your facility is currently covered for stormwater discharge under NPDES Stormwater Permit NCS000087. This
permit will expire on August 31, 1999. North Carolina General Statute 143.215.l(c) requires that an application
for permit renewal be filed no later than 180 days prior to the expiration date. A prior notice of renewal was sent
for this site on February 19, 1999. To date, no response has been received by the Division of Water Quality
(DWQ). In order to assure your continued coverage under the NPDES Stormwater permit, you must apply to
DWQ for renewal of your permit.
Enclosed you will find a 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. The application form must be completed
and returned along with all requested information by May 14, 1999 in order to assure continued coverage under the
NPDES permit.
Failure to request renewal by May 14, 1999 will result in a civil assessment of at least $250.00. 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 $10,000 per day.
If you have any questions regarding the permit renewal procedures please contact Tony Evans of the Stormwater
and General Permits Unit at [phone], ext. 584

11.4 Status and Recommendations for Waters with Noted Impacts
The surface waters discussed in this section are not Impaired. However, notable water quality
problems and concerns have been documented for some waters based on this assessment. While
these waters are not Impaired, attention and resources should be focused on these waters to
prevent additional degradation or facilitate water quality improvement. Waters in the following
section are identified by assessment unit number (AU#). See overview for more information on
AU#s.
11.4.1 Little Buffalo Creek [AU#17-42]
Current Status and 2005 Recommendations
Little Buffalo Creek from source to the Deep River (9.9 miles) is Not Rated for aquatic life
because a benthic community rating could not be assigned at site 1313291. The creek drains urban
areas in Sanford and had steep undercut banks and sandbars. A problematic pump station in this
watershed is scheduled to be eliminated.
Water QuafiInitiatives
In 1998, Sanford received a $765,000 CWMTF (Chapter 34) grant to purchase or acquire
permanent easements on 250 acres along Little Buffalo Creek.
11.4.2 Purgatory Branch [AU#17-40-3]
Current Status and 2005 Recommendations
Purgatory Branch from source to Big Buffalo Creek (2.2 miles) is Not Rated for aquatic life on
an evaluated basis because the Bost Distributing Corporation (NC0081493) had significant
violations of biological oxygen demand permit limits during the assessment period that could
have negatively impacted water quality. Turbidity also exceeded the standard in 8.3 percent of
samples collected at site BA380. The NPDES compliance process will be used to address the
significant permit violations noted above.
11.4.3 Deep River [AU#17-(38.7) and (43.5)]
Current Status and 2005 Recommendations
Deep River [17-(38.7)] from Lee County water supply intake to upstream of Rocky Branch (12
miles) is Supporting aquatic life because no criteria were exceeded at site BA366, although
dissolved oxygen was below 5 mg/l in 14 percent of samples collected during the assessment
period.
Deep River [17-(43.5)] from upstream of Rocky Branch to the Cape Fear River (6 miles) is Not
Rated for aquatic life because Moncure Community Health (NC0030384) had significant
violations of total suspended solids permit limits during the last two years of the assessment
period. Although no criteria were exceeded at site BA383, turbidity was above the standard in
8.3 percent of samples collected at site BA380. This segment is Impaired on a monitored basis
in the fish consumption category and will be added to the 303(d) list of Impaired waters.

'You must monitor quarterly in the first year of your coverage for each benchmark parameter (see Part 3.2.2.1). For
each parameter, no additional benchmark monitoring is required if the average of your 4 monitoring values does not
exceed the benchmark (see Part 3.2.2.3). However, for each parameter there are additional requirements if the
average of your four monitoring values exceeds the benchmark (see Part 3.2.2.4).
'Monitor once per year for each monitoring year.
9 The benchmark value of lead is determined as a function of hardness (in units of mg/L) in the water column. The
value given in Table C-1 (i.e. 0.082 mg/L) corresponds to a hardness of 100 mg/L and should be used if you either
did not analyze water hardness, other hardness data are not available, or the water hardness is less than 100 mg/L. If
a laboratory analysis indicates that the water hardness is below 100 mg/L, then you should use the benchmark for
100 mg/L. If a laboratory analysis indicates that the water hardness is greater than 100 mg/L, then the following
equation may be used to determine the benchmark value for lead:
Benchmark = (e [(1.273)(In hardness) — 1.460))/1000
Example: Laboratory analysis of your water sample indicates the hardness is 175 mg/L.
Benchmark = (e I(1.273)(In 175) — 1.460] )/1000
= (e5.1148)/1000
= 166.46/1000
= 0.17 mg/L

4 The benchmark value of zinc is determined as a function of hardness (in units of mg/L) in the water column. The
value given in Table C-1 (i.e. 0.12 mg/L) corresponds to a hardness of 100 mg/L and should be used if you either
did not analyze water hardness, other hardness data are not available, or the water hardness is less than 100 mg/L. If
a laboratory analysis indicates that the water hardness is below 100 mg/L, then you should use the benchmark for
100 mg/L. If a -laboratory analysis indicates that the water hardness is greater than 160 mg(L, then the following
equation may be used to determine the benchmark value for zinc:
Benchmark = (e [(0.8473)(In hardness) + 0.8841)/1000
Example: Laboratory analysis of your water sample indicates the hardness is 175 mg/L.
Benchmark = (e [(0'8473)(In 175) + 0.8841)/1000
= (e5.26)/1000
= 192.51/1000
= 0.19 mg/L
