Draft NPDES Permit Review — Roxboro Steam Electric Generating Plant, NC0003425
Comments & Recommendations
1. Recommend adding the parameter codes to the tables on the effluent limits pages for each of
the outfalls. Having the codes documented within the permit will assist the facility when using
eDMR.
2. Condition A. (1) — check if the correct footnote is cited on the column header Sample Location
... footnote description pertains to Acute Toxicity.
3. Condition A. (4)—the description within footnote #4 should be corrected to reflect Condition A.
(17) instead of A. (18).
4. Condition A. (4)—footnote 5 should be reflected on the "Daily" measurement frequency for
Ammonia instead of "6".
5. Condition A. (7)— limits and monitoring requirements on internal outfall 008 (Domestic WW)
begin "upon expansion to 0.025 MGD." Should there be a limits page to reflect the
requirements before expansion?
6. Condition A. (12)— for footnote #3, recommend using similar language as footnote #5 within
Condition A. (4) ... 'Ammonia monitoring is only required in the event of an emergency release of
anhydrous Ammonia during the time the released waters are discharged through outfall 012B."
In my opinion, this language is clearer that monitoring is required only when the chemical is
used.
7. Condition A. (12) — modify the measurement frequency for Ammonia to include Daily and
footnote 3... "Daily per discharge event"". This is similar to how the Ammonia measurement
frequency is reflected within Condition A. (4).
8. Condition A. (13) — see items 6 and 7 above.
9. Condition A. (18) — recommend reflecting the instream monitoring requirement in a table
format similar to the effluent limits tables. The table format should quickly stand out to the
permittee and it follows the pattern of the effluent limits and monitoring requirements tables.
10. Condition A. (30)— recommend adding language that specifies the NCDWR units/groups and the
respective mailing addresses where items required by the permit should be sent. The language
could be: "Unless indicated otherwise within the permit, required material should be submitted
to: Division of Water Resources, WQ Permitting Section — NPDES, 1617 Mail Service Center,
Raleigh, NC 27699-1617; and Division of Water Resources, WQ Regional Operations Section —
Raleigh Regional Office, 1628 Mail Service Center, Raleigh, NC 27699-1628".

Summary
The Roxboro Steam Electric Plant is an electric generating facility that uses steam turbine generation (via
four coal-fired units with a total net capacity of 2558 MW). Units No. 1 and 2 (385 MWe and 670 MWe,
respectively) use condensers as cooling devices. Units No. 3 and 4 (707MWe and 700 MWe, respectively)
use cooling towers as cooling devices.
The facility has three existing cooling water intake structures (CWISs). The source water for CWISs No.1
and 2 is the Hyco Reservoir. The source water for CWIS no. 4 is the site's cooling canal. The facility total
intake is approximately 1,114 MGD. The facility discharges to subbasin 030205 in the Roanoke River
Basin. Discharges are mostly industrial, with a very small domestic flow (internal Outfall 008) piped to
the on -site ash pond. Discharges from the ash pond (internal Outfall 002), once -through cooling water
and FGD treatment system (internal outfall 010) are discharged to the Discharge Canal (outfall 003). The
Discharge Canal and Coal Pile Runoff (outfall 006) both discharge to Hyco Reservoir. The Hyco
Reservoir is a 17.6 kmz waterbody constructed in 1963 by CP&L to serve as a cooling water source. The
receiving waterbody is class WS-V; B. The facility is located in the Lower Piedmont area of the state, the
applicable state water quality temperature standard is 3TC (89.6' F).
This facility is subject to EPA effluent guideline limits per 40 CFR 423 - Steam Electric Power Generating
Point Source Category which were amended November 3, 2015. The facility is also subject to the Cooling
Water Intake Structures Rules (40 CFR 125) effective October 14, 2014. The intake flow is > 125 MGD.
The facility operates five internal outfalls and two outfalls to Hyco Reservoir. Duke requested the
addition of three new outfalls on the permit; two to reflect the future treatment systems for the low
volume wastes as the ash basin will be closed and one for the overflow from the east ash basin extension
and stormwater runoff.

NPDES PERMIT FACT SHrr, i
Page 2
Description of existing outfalls:
Roxboro steam Electric Plant
NPDES No. NC00003425
✓ Outfall 003 - Heated Discharge Canal to Hyco Reservoir. The discharge canal combines all internal
outfalls (002, 005, 008, 009, 010) before discharging to Hyco Reservoir. In addition, once -through cooling
water from condensers for units 1,2, and 3, once -through cooling water from heat exchangers, seepage
from ash pond, and stormwater runoff from plant drainage areas are discharged to the discharge canal.
Outfall 006 - Coal Pile Runoff discharges directly to Hyco Reservoir. Coal pile runoff wastewaters
include runoff from the coal pile, limestone pile and gypsum pile, truck wheel wash area and coal
handling areas. Treatment is accomplished by neutralization, sedimentation and equalization.
/✓ Internal Outfall 002 - Ash Pond discharging to the discharge canal. The ash pond receives wastewater
from the following source:
• Bottom ash transport waters
• Silo wash water
• Ash landfill leachate and runoff (this landfill receives CCR from Mayo and Roxboro
plants)
• Dry -ash handling system wash water
• Blowdown from Unit 4 cooling tower
• Coal mill rejects and pyrites
• Sewage treatment plant effluent
• Low volume waste consisting of boiler blowdown, equipment maintenance cleaning
wastewaters, RO reject wastewater and floor drains. Low volume wastes are treated by
neutralization.
• Emergency overflow from FGD system blowdown.
✓ Internal Outfall 005 - Cooling tower blowdown from Unit 4.
Internal Outfall 008 - Treated domestic wastewater. The treatment system consists of a screen,
communitor, surge tank, aeration tank, clarifier, chlorine contact chamber and sludge holding tank. A
new package plant will be installed to replace the existing plant.
✓ Internal Outfall 009 - Chemical metal cleaning waste. Wastewaters from cleaning of the boilers is
generated every five to eight years. Every three to five years wastewaters are generated from cleaning the
heat exchangers. The wastewaters generated can be treated by evaporation or by neutralization and
precipitation.
Internal Outfall 010 - Flue Gas Desulfurization (FGD) treatment system discharging to the discharge
canal. The scrubber system removes SOx by mixing flue gas with a limestone slurry. The blowdown from
the scrubber is discharged to a gypsum settling pond system then to a bioreactor which utilizes
microorganisms to reduce soluble contaminants to insoluble forms (under anaerobic conditions) that then
precipitate from solution. Wastewater is discharged to the ash pond effluent channel. An emergency
overflow from the FGD system blowdown discharges to the ash pond.
Proposed Outfalls:
/Outfall 001- Stormwater and the oveflow from the east ash basin extension. The east ash basin was
closed and subsequently a landfill was built over the old basin. A portion of the basin remained as an
open pond. It has come to the attention of the Division that there are some coal combustion residuals
within the pond. The Division has requested that Duke removes the residuals. In addition to the pond
overflow this outfall discharges stormwater runoff.

NPDES PERMIT FACT SHEET Roxboro Steam Electric Plant
Page 3 NPDES No. NC00003425
Internal Outfalls 012A, 012B and 012C - Low volume waste and other wastewaters. Duke will build two
basin treatment systems to treat wastewaters that now go to the ash basin. The basins will discharge to
the heated canal and an emergency overflow from one of the basins will discharge to Hyco Lake (012C).
CWA 316 (b)
The permittee shall comply with the Cooling Water Intake Structure Rule per 40 CFR 125.95. The Division
approved the facility request for an alternative schedule in accordance with 40 CFR 125.95(a)(2). The
permittee shall submit all the materials required by the Rule with the next renewal application.
Temperature Mixing Zone - Outfall 003
The facility is located in the Lower Piedmont area of the state, the applicable state water quality
temperature standard is 32TC (89.6` F). The authorized temperature mixing zone for outfall 003 includes
the North Hyco Ann downstream of NC Hwy 57, the main body of Hyco Reservoir downstream of the
confluence of the Cobbs Creek Arm and the North Hyco Arm and the entire after bay lake. USGS data at
the after bay monitoring station (USGS Station 02077303) was reviewed for the period of January 2011 to
April 2016. Data shows that the temperature water quality standard was not exceeded for this period.
Maximum temperature recorded was 305C.
Instream Monitoring
The permit requires monitoring of Hyco Reservoir in accordance to the Biological Monitoring Program as
approved by the Division. Based on the Divisions review of the reports the fish community is
comparable to other piedmont reservoirs and no problems were noted. The draft permit includes
instream monitoring for total arsenic, total selenium, total mercury, total chromium, dissolved lead,
dissolved cadmium, dissolved copper, dissolved zinc, total bromide, total hardness (as CaCO3), turbidity,
and total dissolved solids (TDS).

Schedule of Compliance Fly Ash/Bottom Ash:
As per 40 CFR 423.13 (k) (1) (i) bottom ash transport water shall not be discharged, compliance with this
section shall be as soon as possible beginning on November 1, 2020, but no later than December 31, 2023.
Duke utilizes wet bottom ash transport system. Duke is proposing to install a remote mechanical drag
chain system. Design of the system is expected to be completed in 8 months, followed by procurement in
12 months. Construction is expected to be completed in 13 months. Duke proposes a 16 month window
to optimize the system at full load and additional 6 months for potential permitting delays.
Consideration was given to the fact that Duke will be undertaking design, procurement and installation
activities in multiple facilities simultaneously. Duke will meet the no discharge of bottom ash
requirement by April 30, 2021.
Fly ash transport water is no longer discharged therefore Duke meets the compliance date of November
1, 2018.
Internal Outfall 002 - Dewaterine
To meet the requirements of the Coal Ash Management Act of 2014, the facility needs to dewater two ash
ponds by removing the interstitial water and excavate the ash to deposit it in landfills. The facility's
highest discharge rate from the dewatering process will be 2 MGD. The facility submitted data for the
standing surface water in the ash ponds, interstitial water in the ash, and interstitial ash water that was
treated by filters of various sizes. The following pollutants were detected at concentrations higher than
the water quality standards: selenium, arsenic and molybdenum. A new effluent and monitoring sheet is
included in the permit for the ash pond dewatering phase. As this is an internal outfall the water quality
standards are not applied. Monitoring will be required for selenium, arsenic, molybdenum, antimony
and copper.
Outfall 003 - Discharge Canal (Combined outfalls)
DMR/Compliance Review
Data were reviewed for the period of January 2011 to March 2016. There have been no violations of

The facility passed 21 tests out of 21 tests performed for the period of January 2011 to January 2016.
Reasonable Potential Analysis Outfall 003:
The Division conducted EPA -recommended analyses to determine the reasonable potential for toxicants
to be discharged at levels exceeding water quality standards/EPA criteria by this facility from outfall 003.
For the purposes of the RPA, the background concentrations for all parameters were assumed to be below
detection level. The RPA uses 95% probability level and 95% confidence basis in accordance with the EPA
Guidance entitled "Technical Support Document for Water Quality -based Toxics Control." With the
approval of the Triennial Review (2007-2014) of the NC Water Quality Standards by the Environmental
Management Commission (EMC) in 2014 and US -EPA (with some exceptions) on April 6, 2016, the
NPDES Permitting Unit is required to implement the new dissolved metal standards in all permits public
noticed after April 6, 2016. The RPA included evaluation of dissolved metals' standards, utilizing
measured hardness value of 100 mg/ L CaCO3 for hardness -dependent metals.
A reasonable potential analysis was conducted for arsenic, copper, nickel, selenium, strontium, thallium,
chlorides and zinc. Arsenic data used for the RPA was collected between 2011 and 2016. Data for the
remaining parameters was from a special study for the period of March 2010 to August 2011. Based on
this analysis, the following permitting actions are proposed for this permft:
• Monitoring Only. The following parameters will receive a monitor -only requirement since they
did not demonstrate reasonable potential to exceed applicable water quality standards/criteria,
but the maximum predicted concentration was >50% of the allowable concentration: Arsenic,
selenium, chloride.
• No Limit or Monitorf: The following parameters will not receive a limit or monitoring, since
they did not demonstrate reasonable potential to exceed applicable water quality
standards/criteria and the maximum predicted concentration was <50% of the allowable
concentration: copper, nickel, strontium, and zinc.
Mercury Evaluation Outfall 003:
A mercury evaluation was conducted in accordance with the permitting guidance developed for the
implementation of the statewide Mercury TMDL to determine the need for a limit and Mercury
Minimization Plan (MMP). Monitoring for mercury is not required for outfall 003 but mercury data was
collected during a special study during the period of March 2010 to August 2011. The water quality based
effluent limitation (WQBEL) for mercury is 12 ng/1. The technology based effluent limit (TBEL) is 47
ng/l. None of the annual averages exceeds the WQBEL or TBEL, no limit is required. See the attached
mercury evaluation spreadsheet.

Special condition A. (14) in the permit doesn t allow the discharge of the cooling tower blowdown to the
discharge canal, it has to be discharged to the ash pond. With the modifications planned to the site and
the future closure of the existing ash pond Duke will like to have the option to discharge the blowdown
to the discharge canal. This will continue to be an internal outfall subject to the same limits under 40 CFR
423. The limits apply before it comingles with any other waste stream so there is no change in limits or
other permit conditions by allowing the cooling tower blowdown to discharge into the discharge canal.

Schedule of Compliance FGD:
40 CFR 423 establishes compliance dates for the new limitations. Permittee must meet limits as soon as
possible beginning on November 1, 2020 but no later than December 31, 2023.
Duke utilizes a biological treatment system to treat FGD wastewaters. Duke anticipates that it will be
required to install physical/chemical treatment followed by selenium reduction technology to meet the
FGD guidelines. Evaluation of new technologies and design of the system is expected to take 30 months.
The evaluation phase includes evaluation of existing treatment system, flow optimization, siting of the
new system within the plant, selection of technology and permitting. Procurement is expected to be

NPDES PERMIT FACT SH Roxboro steam Electric Plant
Page 10 NPDES No. NC00003425
completed in 20 months, construction and tie-in expected to be completed in 16 months considering that
tie-in has to be done during outages. Startup and optimization under all expected operating conditions is
estimated for 15 months. An additional 6 months is included in the schedule for potential permitting
delays. Duke will meet the FGD ELG by December 31, 2023. As the new treatment system will be placed
in operation and the old pond may still discharge until it is decommissioned. A new outfall is included in
the permit for the new system.
Proposed Outfalls Requirements:
Outfall 001
RPA: An RPA was conducted for proposed outfall 001. RPA was conducted for total arsenic, cadmium,
chlorides, total chromium, total copper, total lead, total mercury, total molybdenum, total nickel,
selenium, total zinc, antimony, sulfate and total thallium. As a result of the RPA limits are required for
the following parameters: arsenic, fluoride and selenium.
Mercury
Mercury data was collected during 2014 and 2015.2014 data was collected using method 245 which has a
higher detection limit that 1631. Data for 2015 was used to evaluate a need for a limit. The annual average
was 5.2 ng/l, no limit will be implemented.

Two new internal outfalls (Outfall 012A and 012B) were added to the permit for the two
proposed retention basins for the treatment of low volume wastes that are now sent to the ash
basin. Duke will build two separate wastewater treatment systems to handle the wastes that go
to the ash pond. These ponds will be in different locations in the site and will require each a
separate outfall into the effluent channel.
Outfall 012C was added to the permit for the emergency overflow of the proposed lined
retention basin discharging through outfall 012B.
A table including a list of all the seeps locations was added to Condition A. (14).
Changes to draft permit from January 2017:
• Seeps special condition was eliminated. Seeps will be addresses through a Special Order by

• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
The permittee shall report discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each
month and submitted electronically using eDMR. The eDMR system allows permitted
facilities to enter moniY g data and submit DMRs electronically using the internet. Until
such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic
Reporting Regulation (CROMERR), permittees will be required to submit all discharge
monitoring data to the state electronically using eDMR and will be required to complete the
eDMR submission by printing, signing, and submitting one signed original and a copy of the
computer printed eDMR to the following address:

If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to
the facility being physically located in an area where less than 10 percent of the households
have broadband access, then a temporary waiver from the NPDES electronic reporting
requirements may be granted and discharge monitoring data may be submitted on paper
DMR forms (MR 1,1.1, 2,3) or alternative forms approved by the Director. Duplicate signed
copies shall be submitted to the mailing address above. See "How to Request a Waiver from
Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month
following the issuance of the permit or in the case of a new facility, on the last day of the
month following the commencement of discharge.
Starting on December 21, 2020, the permittee must electronically report the following
compliance monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Report:
• Pretreatment Program Annual Report
• Clean Water Act (CWA) Section 316(b)
The permittee may seek an electronic reporting w3Wim the Division (see "How to
Request a Waiver from Electronic Reporting" section w).
2. Electronic Submissions'
In accordance 40 CFR 122.410)(9), the permittee must identify the initial recipient at the
time of each el c submission. The permittee should use the EPA's website resources to
identify the initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the
entity (EPA or the state authorized by EPA to implement the NPDES program) that is the
designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that *11 also link to the appropriate electronic reporting
tool for each type of electronic submission and for each state. Instructions on how to access
and use the appropriate electronic reporting tool will be available as well. Information on
EPA's NPDES Electronic Reporting Rule is found at:
Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To
obtain an electronic reporting waiver, a permittee must first submit an electronic reporting
waiver request to the Division. Requests for temporary electronic reporting waivers must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the

and reports. The duration of a temporary waiver shall not exceed 5 years and shall
thereupon expire. At such time, monitoring data and reports shall be submitted
electronically to the Division unless the permittee re -applies for and is granted a new
temporary electronic reporting waiver by the Division. Approved electronic reporting
waivers are not transferrable. Only permittees with an approved reporting waiver request
may submit monitoring data and reports on paper to the Division for the period that the
approved reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are
found on the following web page:

Venessa, this is email is a follow up to the telephone conversation we had today regarding draining the unit 4 cooling
tower at the Duke Energy, Roxboro Steam Electric Plant. As discussed, we have drained the unit 4 cooling tower basin to
our waste water treatment system and at this time plan to drain the water remaining in the unit 4 cooling tower piping
to the heater water discharge canal. This work is scheduled for Saturday March 18, 2018 or Monday March 19, 2018.
Prior to draining this water all required samples will be collected and the total flow will be recorded for reporting on the
monthly DMR. Let me know if you have any questions. Thanks

Subject: Owner Affiliation and Facility Contacts for North Carolina NPDES Correspondence
Duke Energy NPDES Permitted Facilities
Dear Mr. Poupart:
As discussed with you by Richard Baker and Shannon Langley on July 5, 2017, Duke Energy has recently
noted an increased number of documents and correspondence from your agency being directed to the
attention of incorrect staff persons for our NPDES permitted facilities. A few recent examples include
the annual NPDES inspection report for the Mayo Steam Station and a Notice of Violation for the Cape
Fear plant being sent to the Vice President of Harris Nuclear Plant; as well as correspondence for the
Allen Steam Station sent to the South Carolina Director of Environmental Policy. In each case, this has
led to delays in the permitted facility receiving information and impacts our ability to provide time
sensitive responses to the Department of Environmental Quality (DEQ).
Duke staff have discussed this situation with DEQ staff in the central and various regional offices. Based
on our conversations and a review of information captured in your BIMS system, we believe the best
way to address this is with the following included information:
1. A single name/ownership change form to request that the "owner affiliation" for entities Duke
Energy Progress, LLC (DEP) and Duke Energy Carolinas, LLC (DEC) be updated with my contact
information. There appear to be numerous obsolete contacts listed as "owner contact persons"
in your BIMS database- that field can be updated to include my name and the others removed.
2. The "permit billing contact person" should be updated for all facilities to name Cynthia Winston,
Manager, 410 S. Wilmington Street, NCRH15, Raleigh NC 27601. She can be reached at
[phone] and cynthia.winstonCdduke-energy.com.
3. The "facility contact person" for each facility should reflect the Station Manager at the site. A
list of current Station Managers for all DEP and DEC facilities is attached to this correspondence.
4. The fields for "permit contact person" and "persons with signatory authority" have been
recently updated as part of the a-dmr registration process and appear accurate as of this time.
Based on this information, I would envision that general correspondence applicable to more than one
Duke Energy facility, such as groundwater information or other programmatic issues, should be directed

Mr. Jeff Poupart
August 4,2017
to my attention, while station specific communication should be directed to the Station Manager for the
site. Duke Energy will continue to routinely update the DEQ in a timely manner when facility contacts
change. If you think it would be helpful, we would be available to meet with your staff to discuss the
best way to assure accurate delivery of correspondence. We are providing copies of this letter to each
of the regional office supervisors responsible for NPDES permit oversight.
If there are any questions relating to this request please contact Anne Pifer at (980)-373-1609 or
at anne.oiferCdduke-enerev.com.

Additional Site Assessment Req_.. _J
July 8, 2016
The results of the characterization conducted to date in addition to pertinent historical records and
detailed plans for additional site assessments must provide adequate detail to allow technical
review of the proposed actions shall be provided to the DWR. GAPS are due to the DWR Central
Office and the appropriate DWR Regional Office no later than August 19, 2016. Results of related
investigations may be submitted as a CSA Addendum Report at a later date.
In addition to performing site assessment activities, facility site maps must be updated with the
revised waste boundaries and proposed compliance boundaries established according to 15A
NCAC 02L Section .0107. A letter requesting the approval of the new compliance boundaries
shall be submitted to the appropriate DWR Central Office later than August 19, 2016.
The following are background information and approximate locations of the identified areas at
each of the subject sites requiring additional assessment:
James E. Ropers Energy Complex
On November 16, 2015, Duke communicated orally to DWR that a historical coal ash disposal
area located was identified just north of the Broad River and west of the switchyard at the James
E. Rogers Energy Complex. Duke staff estimated the area to be approximately 3 acres in size, but
stated that the full extent of the area is unknown. The approximate location of the area is shown
below encircled. This area was not addressed in the Groundwater Assessment Plan (GAP),
Comprehensive Site Assessment (CSA) report, or Corrective Action Plans (CAPs) submitted to
DWR. Characterization of CCR within the footprint of this disposal area was confirmed by Duke;
however, no data related to this disposal area has been provided to DWR at this time.

Roxboro Steam Electric Plant
Area 1 — This area was discovered by Duke and presented orally to DWR during a joint meeting
on January 14, 2016. This area is located directly east of the East Ash Basin and was subsequently
named by DWR the "Unnamed Eastern Extension Basin" for purposes of prioritization ranking
according to the Coal Ash Management Act. This area shall also include the discharge canal that
runs north along the eastern side of the East Ash Basin. This area was not addressed in the GAP,
CSA report, or CAPs submitted to DWR. The approximate location of the area is shown below

Area 2 — This area is located directly south of the West Ash Basin and encompasses the three
"fingers" of the dammed watershed and the drainage canal that runs north along the west side of
the West Ash Basin. The drainage canal should be assessed for the presence of coal ash and surface
water standards. Based on site visits and information presented in the CSA and CAP reports, DWR
suspects that coal ash may be present in this area. This area was not addressed in the GAP, CSA
report, or CAPS submitted to DWR. The approximate location of the areas is shown below

Hi Danny,
I wanted to give you a heads up on some planned activities at Roxboro. I understand that Autumn has resigned so I am
sending this note to you.
In March we requested confirmation from DEQ that lowering the ash basin at Roxboro to support installation of an
alternate spillway would constitute "essential maintenance" and received confirmation from your central office staff of
this. Both of these documents are attached.
One of the items we indicated we would do associated with this work is provide 48 hour notice that we plan to begin the
work so you were aware when it would be ongoing. I left you a voice mail earlier today but wanted to provide a written
note as well that we plan begin the mobilization for this work on July 5, 2016. Please let me know if there are any
questions about this work. I can send a follow up note when the work is complete if you like.
Let me know if there are any questions.
Thanks.

Dear Mr. Poupart,
EHS-CCP
410 South Wilmington Street
Mail Code: NC 15
Raleigh, NC 27601
In accordance with guidance received from you in a meeting on November 181", 2015, Duke
Energy requests concurrence that temporarily lowering the west ash basin at the subject facility
to install an alternative spillway in the intermediate filter dike is considered "essential
maintenance" under the terms of the subject permit. The engineering plans for the alternate
spillway were submitted to the NC DEQ Dam Safety staff for approval on August 14, 2015.
While there is no immediate threat, the alternate spillway is necessary because an engineering
evaluation suggests the RCP riser structures for the intermediate filter dike do not meet the
criteria for structural stability under seismic conditions. When the alternate spillway is installed,
the existing RCP structure will be properly closed.
In order to install the alternate spillway, the ash basin water level must be temporarily lowered
by approximately two (2) feet. Duke proposes to lower the water level through the use of pumps
with floating intakes. The pumped water will be released through the existing flow path
upstream of internal outfall 002 and final ouffall 003. Flows will be sampled and measured at
internal outfall 002 in accordance with the terms of the subject NPDES permit and results will be
reported on the monthly Discharge Monitoring Report. Verbal notification will be provided to the
DEQ DWR regional office at least 48 hours prior to commencement of lowering the water level
for installation of the alternate spillway.
Duke Energy requests written concurrence that this activity constitutes essential maintenance
and that Duke may proceeded upon DEQ Dam Safety's approval of the plans. If you have any
questions regarding this activity, please contact me at [phone] or
[e-mail].

The Dam Safety Law of 1967 provides for the certification and inspection of dams in the interest
of public health, safety, and welfare, in order to reduce the risk of failure of dams, to prevent
injuries to persons, damage to downstream property, and to ensure the maintenance of stream
flows.
An inspection of the referenced dam was conducted on May 24, 2016 by staff of the Division of
Energy, Mineral, and Land Resources (DEMLR) Raleigh Regional Office. This dam is currently
under a Notice of Deficiency (NOD), issued June 26, 2014 due to internal findings of the
spillway system for the referenced dam. The NOD was revised and re -issued August 11, 2014
based on additional information provided by a consultant's report addressing further review of
the camera inspection for the spillway system associated with the subject dam. Not all
deficiencies have been addressed as of this date and therefore, the NOD is still in effect. The
May 24, 2016 inspection did not note any significant externally observed findings, but does
recommend the following items pertinent to maintenance and operation of the dam:
Periodically monitor the dam and appurtenant works with respect to elements affecting their
safety. This is in light of the legal duties, obligations, and liabilities arising from the ownership
and/or operation of a dam. Your current inspection program is an appropriate way to address
this recommendation.

During this inspection we also investigated the potential for property damage and loss of life in
the event that your dam fails. This investigation determined that failure of your dam could result
in significant property damage downstream. Therefore, we are listing your dam in the
"Intermediate Hazard" category.
Also be advised that any excavations in this dam or major repair work to this dam must be
approved by this Office before any work is done. Also, note that this dam may not be breached,
meaning the dam may not be drained by cutting a notch in the dam, without prior engineered
breach plans being submitted to and approved by this Department.
Please be advised that though we make every reasonable effort to determine the safety of your
dam, our resources limit us to surficial inspection. There is no certainty regarding the internal
stability of the dam. Dams, and especially their spillways and conduits, deteriorate with age.
Therefore, you are advised to keep a close watch on your dam and to notify us if you detect any
changes, especially cracks, ground movements, or changes in seepage rate or color.
Your cooperation and consideration in maintaining a safe dam is appreciated. If ownership of
the dam has changed, or if you are not responsible for the dam, please notify us so that we can
update our records. Should you have any questions concerning our inspection, please contact
Diane Adams or me at [phone].

Dear Mr. Poupart,

NC DENR kd;O; Jh Regfc_31 L,,
OO
In accordance with guidance received from you in a meeting on November 18"', 2015, Duke
Energy requests concurrence that temporarily lowering the west ash basin at the subject facility
to install an alternative spillway in the intermediate filter dike is considered "essential
maintenance" under the terms of the subject permit. The engineering plans for the alternate
spillway were submitted to the NC DEQ Dam Safety staff for approval on August 14, 2015.
While there is no immediate threat, the alternate spillway is necessary because an engineering
evaluation suggests the RCP riser structures for the intermediate filter dike do not meet the
criteria for structural stability under seismic conditions. When the alternate spillway is installed,
the existing RCP structure will be properly closed.
In order to install the alternate spillway, the ash basin water level must be temporarily lowered
by approximately two (2) feet. Duke proposes to lower the water level through the use of pumps
with floating intakes. The pumped water will be released through the existing flow path
upstream of internal ouffall 002 and final outall 003. Flows will be sampled and measured at
internal ouffall 002 in accordance with the terms of the subject NPDES permit and results will be
reported on the monthly Discharge Monitoring Report. Verbal notification will be provided to the
DEQ DW R regional office at least 48 hours prior to commencement of lowering the water level
for installation of the alternate spillway.
Duke Energy requests written concurrence that this activity constitutes essential maintenance
and that Duke may proceeded upon DEQ Dam Safety s approval of the plans. If you have any
questions regarding this activity, please contact me at [phone] or
[e-mail].

Dear Mr. Chernikov,
Duke Energy personnel collected a water quality sample of AOW S-18 at Roxboro Steam
Station on 21 August 2015, and the laboratory report containing the results of the water quality
sampling was received on 10 September 2015. Enclosed with this letter are the results of the
water quality sampling.
The boron result suggests that the water is influenced by coal combustion residuals, however,
the exact source is unknown. The water of this AOW emerges from under the sluice lines, flows
along the sluice lines, and enters a gully whose water flows into Roxboro's heated water mixing
zone north of the ash basin.

Hi Shannon,
Hope you had a great holiday break!
Cheng and I have been asked to complete an NPDES wastewater permit compliance sampling and toxicity
sampling inspection this quarter at the Roxboro Power Plant.
Since this takes quite a bit of planning, and DWR Lab has a narrow window (February 29 — March 111 week) in
which the lab is able to support fat head minnow toxicity samples. March is when the plant also needs to
complete Toxicity, so we are thinking this could be the easiest planned together well ahead.
I wanted to propose starting inspection and sampler set-up on Monday, February 29 with return on Tuesday,
March 1, 2015 to retrieve the samples and carry them to the lab. We could plan to take the NPDES effluent
003 and 006 grab samples Tuesday when we pick up composites, if that works. Parameters to be sampled will
be exactly parameters described in the current permit(2007/2009 version, as no new permit has yet been
issued) for outfall 003 and outfall 006.
Can you let know if works you and for plant staff?
Thank you for time and consideration.

Re: Roxboro Steam Electric Generating Plant
NPDES Permit No. NC0003425 — Person County, North Carolina
Conditional Approval of Revised Groundwater Assessment Work Plan
Dear Mr. Sideris:
Donald R. van der Vaart
Secretary
On December 31, 2014, the Division of Water Resources (Division) received the revised
Groundwater Assessment Plan (GAP) for the above listed facility. The revised GAP was submitted
in response to the DWR's Review of Groundwater Assessment Work Plan letter dated November 4,
2014. A review of the plan has been completed and several deficiencies or items requiring
clarification were noted. Therefore, in order to keep the site assessment activities on a timely
schedule, the Division has approved the revised GAP under the condition that the following deficient
items are addressed in the Groundwater Assessment Report:
• Comment Section 5.3 Hydrogeologic Site Characteristics:
Information needed to develop the initial site conceptual site model (ISCM) was available in
the revised GAP, but for the most part data were not provided in a clear, cohesive manner to
Illustrate where data gaps may exist. Duke Energy should incorporate all existing data at the
site and be prepared to collect additional data if the Division determines that additional data
gaps exist. Continued site conceptual model development should follow guidelines similar to
those presented in the American Standards Testing Measures E1689 - 95(2014) Standard
Guide for Developing Conceptual Site Models for Contaminated Sites to direct data
collection, data interpretation, and model development efforts.
Non-compliance wells MW-1 and MW-2 are noted in the introduction of Section 6.0
Environmental Monitoring along with corresponding analytical results provided in Table 4;
however, these wells are not shown in any maps in the GAP. Show the locations of wells
MW-1 and MW-2 along with the locations of any other voluntary monitoring wells on all
maps developed for the comprehensive site assessment (CSA) report. If other reports or data

relevant to groundwater contamination and (or) hydrogeologic assessment exist, they should
also be used and documented in the CSA report.
• Comment 7.1.1.1 Borings within the 1966 Semi -active and 1973 Active Ash Basins:
The Division suggests installing a bedrock monitoring well located in the vicinity of
proposed locations AB2/ABMW-2S/D to address a data gap within the 1973 Active Ash
Basin.
Installation of a bedrock monitoring well is suggested in the vicinity of proposed well cluster
location AB-7/ABMW-7/7D to address a data gap downgradient of the Lined Landfill and
near the 1966 Semi -active Ash Basin where elevated concentrations of boron, selenium, and
total dissolved solids have been detected at coal combustible residuals (CCR) landfill
monitoring wells GMW-6 and GMW-11.
These additional bedrock monitoring locations will provide data for assessment of multiple
flowpath transects across the site. The Division recommends that wells installed through the
ash basins into native materials are doubled cased to protect well integrity.
• Comment Section 7.1.2.5 Downgradient Assessment Areas
Proposed monitoring well location MW-4BR is planned to assess groundwater in the bedrock
at the area in the immediate vicinity of current compliance well CW4. According to the
GW-1 well form, CW4 monitors the partially weathered rock and bedrock interface.
Therefore, the screened interval for MW-4BR would better address site assessment
objectives if it monitors a deeper discrete interval within the bedrock than what is
characterized in CW-4.
• Comment Section 7.1.4 Hydrogeologic Evaluation Testing
Slug tests will be performed in a subset of existing wells as well as all of the new wells,
including some of the piezometers installed as part of the Landfill Expansion Phase 7-9
Hydrogeologic Investigation. In addition, vertical hydraulic conductivities in the ash and
saprolite will be determined in accordance with ASTM Standard D-5084 from samples
collected in Shelby tubes for geotechnical analysis. The borings where these samples are
collected in Shelby tubes will be based on site -specific conditions encountered during the site
assessment. These test results will provide a more robust dataset to characterize site
conditions and refine the flow and transport models.
• Comment Section 7.2 Ash Pore Water and Groundwater Sampling and Analysis:
Direction provided in the EPA Region 1 Low Stress Purging and Sampling Procedure for the
Collection of Groundwater Samples from Monitoring Wells (2010) should be followed
strictly and any deviations from the procedure must be approved by the Division and
documented accordingly. For example, samples should not be collected until pH is stabilized
within t 0.1 for three consecutive readings rather than t 0.2 written in the GAP.
Temperature and specific conductivity readings should stabilize within 3% for three
consecutive readings before samples are collected instead of 10% noted in the GAP. Also
note that if the pumping rate is so low that the flow-through-cell/chamber volume cannot be
replaced in a 5 minute interval, the time between measurements should be increased
accordingly.

Roxboro Steam Electric Generating Plant
March 5, 2015
Page 3 of 3
• Comment 7.8.2 Development of Kd Terms
It is expected that additional solid phase samples will be collected and analyzed for Kd
determination as well as physical properties at strategic locations along flowpath
transects. These data will refine the assessment of water geochemistry and development
of flow and transport models.
In addition, technical direction that will serve as the basis of expectations for completion of the site
assessment is provided at Attachment 1. Failure to address the deficient items stated above will
result in Duke Energy not being in compliance with the stated statutes. Per G.S. 130A-309.209(a)
(3) and (4), you must begin implementation of the revised GAP on March 16, 2015 and the
Groundwater Assessment Report is due on September 2, 2015. It is our understanding that Duke
Energy may have to obtain additional permits to facilitate installation of certain monitoring wells. In
the event permits are needed for this purpose, Duke Energy should take all steps necessary consistent
with the law to avoid delaying completion of the assessment report.
If you have any questions, please contact Eric Rice at [phone].

Duke Energy GAP Review Issues
The items identified in this Groundwater Assessment Plan (GAP) review summary are provided for
general discussion for the various parties to agree upon technical direction and content in the revised
GAPs, comprehensive site assessments (CSAs), and corrective action plans (OAPs).
Groundwater Monitoring
1. A schedule for continued groundwater monitoring is mandated by the Coal Ash Management
Act 2014. An interim plan should include.at least two rounds of groundwater samples collected
and analyzed in 2015. The analytical results of the first round of data collected in 2015 would be
included in the CSA report, while the results of the second round would be submitted as a CSA
addendum. After CSA data can be evaluated, a plan for continued groundwater monitoring can
be developed for implementation in 2016.
2. Sites impacted by inorganics are typically managed using a tiered site analysis which includes
four elements as referenced in EPA/600/R-07/139:
• Demonstration of active contaminant removal from groundwater & dissolved plume
stability;
• Determination of the mechanism and rate of attenuation;
• Determination of the long-term capacity for attenuation and stability of immobilized
contaminants, before, during, and after any proposed remedial activities; and
• Design of performance monitoring program, including defining triggers for assessing
the remedial action strategy failure, and establishing a contingency plan.
This reference and the framework described above should be used as applicable to meet
the corrective action requirements found in 15A NCAC 02L .0106.
3. Because of uncertainty concerning the site's ability to attenuate contaminants over the long
term given potentially changing geochemical conditions, there is a need to address the elements
of the tiered site analysis described above and collect appropriate samples as part of the CSA,
CAP development, and continued groundwater monitoring.
4. The Division of Water Resources (Division) Director is responsible for establishing background
levels for COPCs in groundwater. This determination is based on information and data provided
by the responsible party and may include formal statistical testing using background wells with
at least four rounds of data. Wells identified as "background" are subject to periodic review
based on a refined understanding of site chemistry and hydrogeologic conditions. In general,
each facility must have a background well or wells screened or open to each of the dominant
flow systems that occur at the site and are associated with groundwater contamination. Any
questions concerning adequacy of background monitoring locations or conditions at the
facilities should be directed to the Regional offices.

N
W
Attachment 1
Page 2 of 6
S. Delineation of the groundwater contaminant plume associated with coal combustion residuals is
a requirement of the investigation and if off -site monitoring wells are ultimately required to
perform this task, then it is expected that these activities will be completed as part of the
groundwater assessment activities and included in the final report. Documentation of the effort
to gain off -site access, or right of way permits, will be provided if off -site access is denied or
alternate means of assessing the area were not available within the allocated timeframe (such
as within right-of-ways).
Site Assessment
Data Requirements and Sampling Strategy
1. Robust data collection is warranted to support timely completion of site assessments and
subsequent corrective action plans because of the impending deadlines for completion of CSAs
and CAPS, scale and geologic complexity of the sites, the challenges of modeling heterogeneous
systems, and site proximity to potential human and sensitive ecosystem receptors.
2. Robust data collection will be focused along strategically positioned flowpath transect(s) - from
ash pond source to potential receptor —as an efficient approach for model development
(analytical, geochemical, groundwater flow, and transport) in support of risk assessment and
CAP development. Data collected to support evaluation of site conditions along the flowpath
transects should be located along or defensibly proximate to the modeled transects.
3. The dataset developed along proposed flowpath transects will include any information needed
to determine constituent concentrations, conduct Kd tests, and perform batch geochemical
modeling in multiple flow horizons as appropriate. This data will include a) solid phase sample
collection for Kd measurement and batch geochemical modeling, inorganic analysis and
speciation, and other parameters identified in General Comment #4 of the November 4, 2014
GAP comments issued by DWR, b) solution phase sample collection for total and dissolved
inorganic analysis of total concentrations, small pore filtration for dissolved samples, etc., and c)
slug, constant/falling head, and packer testing. The solid phase sample mineralogy, total
concentration results, re-dox measurements, and other geochemical parameters will be used as
input for equilibrium speciation calculations of redox sensitive constituents calculated by
PHREEQC or similar program (EPA/540/5-92/018). This geochemical modeling will be performed
to identify potential mineral phases, estimated species speciation and concentrations, and will
be performed varying key solubility controlling parameters to predict mineral phases,
speciation, and concentrations under varying conditions. Solid samples for Kd tests collected
from along from proposed flowpath transects will be handled and preserved in order to
eliminate exposure to ambient air in the field. Kd samples should be collected in plastic bags
and sealed with a conventional vacuum plastic bag sealer. The samples will be then placed on
ice in a cooler for transport and kept out of direct sunlight. Once received by the analytical
laboratory, the Oxidation -Reduction Potential (ORP) of the sample will be measured using an
ORP probe and meter in accordance with ASTM method G200-19 (Reapproved 2014). Based on
this ORP measurement, either normal or "glove -box" processing of a sample will be applied

N

Attachment 1
Page 3 of 6
(EPA/600/R-06/112). An additional sample will be retained, pending confirmation of subsequent
ORP and DO testing. ORP and dissolved oxygen will be measured in the groundwater monitoring
wells subsequently installed at these sample locations. In the event that the groundwater field -
measured ORP and DO reveal reducing conditions, the additionally -retained sample will be
subject to glove box processing for the Kd analyses. Refer to EPA/600/R-07/139 Section III for
the data collection and characterization needed to support the four -tiered analysis discussed
above.
4. Speciations for groundwater and surface water samples should include Fe, Mn, and any COPCs
whose speciation state may affect toxicity or mobility (e.g. As, Cr, Se, or others if applicable).
This speciation will apply for groundwater samples collected at wells located along proposed
flowpath transects and in wells where these constituents exceed 2L groundwater standards as
well as for surface water samples collected within ash impoundments.
5. Solid phase samples shall be analyzed for: minerals present, chemical composition of oxides,
hydrous Fe, Mn, and AL oxides content, moisture content; particle size analysis; plasticity;
specific gravity; porosity; permeability, or other physical properties or analyses needed to
provide input to a chosen model. These analyses for physical properties will be conducted at up
to 15 locations along proposed flowpath transects where Kd samples are collected. Solid phase
samples at up to 15 additional locations will be collected and analyzed for hydrous ferric oxide
(HFO) content. At these additional locations where HFO content is analyzed, analyses for
physical properties will not be performed. Solid phase samples will be analyzed for total organic
content from the same locations where samples are collected for Kd determination. Solid phase
samples will be analyzed for total organic carbonate content from the same locations where
samples are collected for Kd determination only at facilities located in the coastal plain.
6. In addition to conducting the SPLP leachable inorganic compounds analysis for selected ash
samples to evaluate the potential for leaching of constituents to groundwater, the leachable
analysis should also be conducted for some soil samples from locations beneath the ash ponds,
within the plume, and outside the plume to evaluate potential contributions from native soils.
7. In addition to collecting solid phase samples onsite for Kd procedures, soil samples should be
also collected from unaffected soils within groundwater flow pathways to evaluate Kd(s) or
hydrous ferrous oxide.
8. Rock samples for laboratory analyses should be collected as commented in General Comment 4
of the November 4, 2014 GAP comments issued by DWR. This GAP review comment indicated
that the sample(s) collected from bedrock well soil and rock cores shall be analyzed, at a
minimum, for the following: type of material, formation from which it came, minerals present,
chemical composition as oxides, hydrous Fe, Mn, and AI oxides content, surface area, moisture
content, etc.; however, these analyses were not mentioned in the GAP. The Division reserves
the right to request analysis for organic carbon content, organic carbonate content, and ion
exchange capacity if needed to complete the site assessment process.
9. The coal ash and soil analyte lists should match the groundwater analyte lists.
10. Total uranium analysis should be analyzed where total radium is analyzed for groundwater.

11. If analytical results from a seep sample exceed 2L standards, then the area in the vicinity of the
sample location should be investigated for groundwater contamination. If analytical results
from a surface water sample exceed 2B standards, then the area in the vicinity of the sample
location should be investigated for groundwater contamination.
12. Surface water/seep samples should be collected during baseflow conditions and that the
groundwater monitoring (water levels and sampling) should occur at about the same time.
13. Measurement of streamflow in selected perennial streams is expected as needed in support of
simulation/calibration of flow and transport models; major rivers that serve as groundwater
divides are not included in this expectation.
Conceptual Model Elements
1. In the CSA report, data gaps remaining should be specifically identified and summarized.
2. Site heterogeneities should be identified and described with respect to: a) their nature, b)
their scale and density, c) the extent to which the data collection successfully characterizes
them, d) how the modeling accounts for them, e) and how they affect modeling uncertainty.
3. The impact of data gaps and site heterogeneities should be described in relation to the
elements developed in the Site Hydrogeologic Conceptual Model and Fate and Transport
Model subsections.
4. For sites in the Piedmont or Mountains, the CSA Report should include a subsection within the
Site Geology and Hydrogeology Section titled 'Structural Geology'. This section should
describe: a) foliations, b) shear zones, c) fracture trace analysis, and d) other structural
components anticipated to be relevant to flow and contaminant transport at the site.
5. Duke Energy will include a poster -sized sheet(s) (ANSI E) combining tabulated analytical
assessment results (groundwater, surface water, and leachate samples); multiple sheets may
be needed to present the data. This should be provided in addition to the individual analytical
results tables that will be prepared for the CSA reports. Any questions concerning format or
content of the analytical result summaries should be directed to the Regional offices.
Geochemical Modeling
1. The Division agrees that a geochemical model "coupled" to a 3-D fate and transport model is
inappropriate given the size and complexity of the sites and the extremely large amount of data
required to calibrate such a model. Rather, a "batch" geochemical model approach should be
sufficient for successfully completing the site assessment and/or corrective action plan.
2. Samples collected for "batch" geochemical analysis should be focused along or defensibly
proximate to flowpath transects.
3. To support successful batch geochemical modeling, dissolved groundwater samples collected
along a contaminant flowpath transect should be obtained using a 0.1 um filter. This will help
ensure a true dissolved phase sample. Note that the dissolved samples are for assessment
purposes only and may not be used for purposes of compliance monitoring. If there is
uncertainty about which areas/wells will be used in the batch geochemical modeling, the initial
round of assessment sampling at the facility can utilize the 0.45 um filter until the contaminant

0
40
Attachment 1
Page 5 of 6
flow path transects are selected. Once determined, Duke Energy can go back and re -sample the
wells needed for geochemical modeling using the 0.1 um filter. It is recognized that the use of a
0.1 um filter will be difficult for wells with elevated turbidity; in this case, it is recommended
that Duke Energy use two filters in series (the water initially passes through a 0.45 um filter to
remove larger particles prior to passing through the 0.1 um filter). Information for a disposable
0.1um field filter designed specifically for sampling groundwater for metal analysis is provided at
the following link: http://www.vosstech.com/index.php/products/­filters. If field comparisons of
0.1 versus 0.45 micron filtration at several transect wells at a given site show no significant
differences between the two methods, then 0.45 micron filters may be used for evaluating the
dissolved phase concentrations at that site.
4. In support of the objectives of General Comment #2 of the November 4, 2014 GAP comments
issued by DWR , Duke Energy should add a column titled 'relative redox' to the analytical results
tables to record the geochemical conditions for that location/sample date. The redox
determination should be based on observed DO, ORP, and any other relevant measures and
presented for historic and new samples (wells, ash pore water, surface waters, etc.). Relative
redox designations may include "iron reducing", "sulfate reducing', mildly oxidizing, moderately
oxidizing, etc. and should be footnoted with a statement about the degree of confidence in the
designation based on amount and quality of available data.
5. Duke Energy shall also evaluate: a) spatial geochemical trends across the facility and along
selected flow paths, b) temporal geochemical trends where observable (such as for compliance
boundary wells), along with the likely reason for the change (e.g. increase in seasonal recharge,
pond de -watering and subsequent reversal of groundwater flow direction, inundation of well
from river at flood stage, etc.) in support of the CAP. This evaluation step will require a
comparison of geochemical conditions over time with rainfall data, notable ash capping,
dewatering, disposal/removal, or other plant operations, etc. The quality of existing
geochemical data will be evaluated using field notes, calibration records, and consistency in
redox measurements (e.g. eH vs. raw ORP).
Groundwater Models
1. The technical direction for developing the fate and transport modeling will follow guidelines
found in Groundwater Modeling Policy, NCDENR DWQ, May 31, 2007, and discussions
conducted between Duke Energy and their consultants with the Division. Ultimate direction for
completion of fate and transport models will be provided by the Division.
2. The CAP Report should include a subsection within Groundwater Modeling Results titled 'Site
Conceptual Model' that succinctly summarizes, for purposes of model construction, the
understanding of the physical and chemical setting of the site and shall include, at a
minimum: a) the site setting (hydrogeology, dominant flow zones, heterogeneities, areas of
pronounced vertical head gradients, areas of recharge and discharge, spatial distribution of
geochemical conditions across the site, and other factors as appropriate), b) source areas and
estimated mass loading history, c) receptors, d) chemical behavior of COPCs, and 0 likely

Attachment 1 as
Page 6 of 6
retention mechanisms for COPCs and how the mechanisms are expected to respond to changes
in geochemical conditions.
3. Modeling will be included in the Corrective Action Plan (CAP). The four -tiered analysis
previously referenced and appropriate modeling should be conducted, and the mass flux
calculations described in the EPA/600/R-07/139 should be performed.
4. The CAP Report shall provide separate subsections for reporting groundwater flow models and
fate and transport models.
5. The CAP Report should include subsections within Groundwater Modeling Results titled
'Groundwater Model Development' that describes, for each chosen model: a) purpose of model,
built-in assumptions, model extent, grid, layers, boundary conditions, initial conditions, and
others as listed in Division guidance. Include in this section a discussion of heterogeneities and
how the model(s) account for this (e.g. dual porosity modeling, equivalent porous media
approach, etc.). Separate subsections should be developed for the groundwater flow model,
fate and transport model, and batch geochemical models, respectively.
6. CAP Reports should include a subsection within Groundwater Modeling Results titled
'Groundwater Model Calibration' that describes, for each model used, the process used to
calibrate the model, the zones of input and calibration variables (for example, hydraulic
conductivities) that were used, the actual (measured) versus modeled results for all key
variables, and others. Separate subsections should be developed for the groundwater flow
model, fate and transport model, and batch geochemical model(s), respectively.
7. CAP Reports should include a subsection within Groundwater Modeling Results titled
'Groundwater Model Sensitivity Analysis' that describes, for each model used, the process used
to evaluate model uncertainty, variable ranges tested, and the key sensitivities. Separate
subsections should be developed for the groundwater flow model, fate and transport model,
and batch geochemical model(s), respectively.
Development of Kd Terms
1. Kd testing and modeling in support of CAP development should include all COPCs found above
the NCAC 15A 02L .0106(g) standards in ash leachate, ash pore water, or compliance boundary
well groundwater samples.
The selected Kd used in transport modeling often will profoundly affect the results. Duke
Energy should acknowledge this concept and document within the transport modeling section(s)
of the CAP all widely recognized limitations inherent in the estimation of the Kd term.
Risk Assessment
1. Provide references for guidance and potential sampling methodology related to conducting a
baseline ecological risk assessment or habitat assessment, if warranted.

'2014 Environmental Monitoring Report'.
Dear Mr. Mosely:
Matthew Stillwell, Jeff DeBerardinis, and Debra Owen of my staff have reviewed the 2014 Environmental
Monitoring report for fish community structure, fish tissue, and physical -chemical data respectively. This report
was received by the Water Sciences Section (WSS) on January 12', 2015.
In terms of fish tissue data, trends indicate very little change in metal concentrations in Hyco Lake fish tissues
and these levels have remained well below the North Carolina Department of Human Health Service's
(NCDHHS) action levels for Se and Hg and for screening values for As, Cd, and Cu. In addition, there have
been no significant changes in the physical chemical water chemistry values over time.
Based on a review of the 2014 data provided, the historic fish biomass, abundance, relative weight, and quality
of the fishery present in Hyco Reservoir is comparable to the levels associated with these parameters as
reported by Duke -Progress biologists over the last several years. In addition, there are no significant
differences in the fishery uplake to downlake. As a result, based on the current and historical data provided, the
2014 fishery data meet the definition of a Balanced and Indigenous Population.
However, for inclusion in future reports please add historic fish community structure data. Historic data is
already included for water chemistry parameters and for fish tissue data but is not included for the fish
community. Including this data in subsequent reports will expedite our review. Specifically, please include
historic data for the following fish community parameters: fish biomass, abundance, and relative weight. The
fishery data should include the same historic reporting years as water chemistry parameters and fish tissue.
If you have any questions, please do not hesitate to
contact me or my staff.

On December 15, 2014, the NC Division of Water Resources mailed a Compliance Evaluation
Inspection Report for the Roxboro Steam Electric Power Plant. This report was completed
following an NPDES Wastewater Discharge Permit No. NC0003425 site inspection on
November 19, 2014. Mr. Shannon Langley, contacted the Raleigh Regional inspector to discuss
the DMR revision recommendation that was included in the inspection report.
After discussion with Shannon Langley and a review of the calendar days represented in the 7-
consecutive day time frame, it was determined that the facility met the reporting requirement
and that the frequency violation flagged was in error. This error will be reported to the
Information Technology Group for further evaluation and the action in the DWR BIMs System
will reflect a BIMs Calculation Error.

Hi Autumn.
Our records indicate we submitted the report for Mayo to "Danny Smith" on February 22 by
certified mail and it was signed for on February 25th. The report was a little bit over 20
pages long.
Around that same time you and I discussed the Roxboro chemical addition trials. At Roxboro,
we never added any bisulfite because the FGD ORP never went outside the desired range during
the trial. Because of this there was nothing to report on at Roxboro.
Let me know if you need anything else.
Thanks.

Subject: Can you update me on the status of late 2012 Re -emission reduction trails at May and
Roxboro?
Hi Shannon,
I was reviewing some of my a -mails on trials at the Mayo Plant last year and came across
discussions with Steve Cahoon on Hg Re -emission Reduction efforts and a trail using sodium
hydrosulfide at Mayo and possibly Roxboro.
Can you refresh my memory, I think you spoke of these trails and said that they were ended,
but I do not recall receiving any written results of the trails.
I just wanted to document the dates the trails were ran -if they were ran, and confirm the
concluding results.
Here is Steve's email:
Autumn,
Progress Energy is notifying the Raleigh Regional Office of a temporary planned change at the
Mayo Plant. As you are aware we are in the process of conducting several studies at the Mayo
Plant designed to help improve the quality of the waste water discharge at Outfall 009 and
Outfall 002. Our Strategic engineering group is investigating a possible mercury re -emission
mitigation reagent trial at Mayo this fall. The trial is focused on air emissions; however
t

there may be slight change in the wastewater discharge at the plant as a result of the use of
sodium hydrosulfide. The desired trial window is a 14 day period between 9/4and 10/6. This
trial would be contingent on the mercury profiling results in ]uly demonstrating that mercury
reemission is occurring. This trial will most likely be performed by B&W and the chemical
supplier TDC. The reagent is a solution of sodium hydrosulfide (NaHS) that is injected into
the scrubber slurry from one of the existing ports on the AR pumps. The reagent MSDS is
attached to this email.
The NaHS solution reduces mercury reemission in the wet FGD by acting as a sulfide -donating
liquid which increases Hydrogen Sulfide (H2S) which reacts with a portion of the oxidized
mercury to form Mercury Sulfide (HgS) at the gas phase boundary. This sequesters the mercury
as a insoluble solid that precipitates into the gypsum cake thus preventing reduction of
oxidized mercury to elemental form. Expected injection rates for this trial range from 0.5
gpm up to 1.0 gpm depending on blowdown rate to maintain a minimum concentration that
prevents Hg reemission. This corresponds to -0.4 - 1.2 ppm of NaHS in the scrubber solution.
The formation of insoluble HgS by NaHS may increase the mercury bound in the gypsum thus
reducing mercury in the waste water stream. Any residual NaHS in the waste water stream is
expected to be readily decomposed by the controlled partial oxidation of sulfide to elemental
sulfur catalyzed by naturally occurring microorganisms of the genus
Halothiobacillus<htty://en.wikipedia.ore/wiki/Halothiobacillus> in the bioreactor and
environment. These natural, living microorganisms present in the bioreactor catalyze the
sulfur conversions and are, by their nature, resilient and adaptive. As such no detrimental
impact on the bioreactor is expected nor wastewater other that a potential for a increase in
sulfur solids.
We'll receive a report from our vendor discussing the trial results and recommendations
moving forward. Please review the information above and let me know if you have any
questions, concerns or suggestions to aid us as we prepare to proceed with this trial.
Thanks in advance for your time and consideration.

Autumn,
Here are some more specifics to address your questions.
GE will provide a report on the effectiveness of the chemical addition after the Vial is
completed. We can provide you a copy if you would like. This should contain the
information you referenced below. I would not expect it to be available until
sometime after the first of the year.
Additional ORP measurement instrumentation will be installed at the bioreactor inlet
prior to commencing this trial. ORP instrumentation is also being installed in the
scrubbers. This instrumentation will be left in operation going forward.
Sodium bicarbonate will be added to the blow down water at the blow down pump
outlet based on alkalinity which will be measured by taking daily samples. Addition
rates will be adjusted based on the alkalinity. It is expected that the current alkalinity
levels will be maintained.
Sodium Bisulfite/Ammonium Bisulfite will be added to the bioreactor inlet based on
the continuous ORP monitoring at this location. I have been told that the SBS/ABS
will only be added if the ORP at the bioreactor inlet is in the high 300's (> 350 or
closer to 400 mV).
Caustic will be added to maintain a pH of 7 at the bioreactor inlet and this will be
controlled by the pH meters.

Subject: Notification of potential change in wastewater
Hi Autumn,
I wanted to send you a notification of a potential change in NPDES discharge. This
change is very similar to what has been submitted to you in the past for the Mayo
Plant.
The Roxboro Steam Plant (NPDES Permit # NC0003425) plans to perform a trial
1g= of 100% Illinois Basin (ILB) Coal on Unit 3 and Unit 4 beginning at some point
during the 4th quarter of this year. High sulfur Northern Appalachian (NAPP) coal is
planned for Roxboro Units 1 and 2. The trial bum should last for 30-45 days.
Combustion of these coals is expected to result in a potentially high oxidation-
reduction potential (ORP) via the FGD blow down to the bioreactor. This will be
monitored closely. In order to reduce the ORP to ensure the continued bioreactor
performance, the following chemical additions to the FGD blowdown wastewater
have been recommended by GE® are being planned during the trial.

Ps. I spoke to Steve Cahoon about the written report for the Mayo trial burn. He
reminded me that the Mayo trial burn was delayed due to the plant being offline
earlier this year for an unplanned outage. We are awaiting the Mayo report from GE.

Subject: Anodamine trial
Attachments: MSDS Anodamine HPFG+ 2013.pdf
Hi Autumn,
As we discussed briefly on the phone recently, the Roxboro Steam Plant plans to pursue a trial with a film forming
passivation scale and corrosion Inhibitor to be used during "layup" of generation units at the site. A copy of the MSDS
for the proposed product (AnodamineTM) is attached to this email. Note that Section 12. Ecological Information
indicates that the LC50 for the most sensitive organism tested (Pimephales) is 49,210 mg/l.
The Roxboro plant plans to initially trial this product in the "layup" of Unit 1 but may want to try it in other Units as well.
The purpose is to evaluate the products effectiveness in reducing iron and copper transport in the chemistry cycle.
The product would be introduced into the boiler chemistry cycle at a concentration of at least 1.0 mg/I. Upon reaching
the desired residual concentration of the product, the boiler would be shut down and either drained or remain full
during the shutdown period. As you know, most of the product should interact with the interior metal surfaces in order
to establish a "barrier" to ionic mobility and 1.) provide protection during layup and 2.)reduce corrosion during startup.
A small amount of the AnodamineTM could be contained in the boiler blow down water sent to the ash pond and/or the
boiler draining water sent to the ash pond. Any concentrations of AnodamineTM within water sent to the ash pond
would be greatly diluted by ash sluice, low volume waste and once through cooling water prior to reaching the Hyco
reservoir.
The plant plans for the trial to run through at least three planned startup/shutdown cycles so the effectiveness of the
product can be evaluated overtime. The length of time the trial would take is unknown because the units may be
needed to run for extended periods without shutdown. The plant proposes to trial the product during least three
planned startup and shutdown cycles.
Should the trial prove effective, we would provide an update to our NPDES application to add this chemical for more
routine use. Please advise if you have any specific questions or concerns with this proposal.
Thanks.

Jessica,
The NPDES permit effluent monitoring is surface water, as water quality standards are based on surface water
sampling, but other sampling can be required and will be specific to the NPDES permit. An example would be
groundwater monitoring is listed in some of the NPDES permits.
The Self Report biological monitoring is specific to the biological monitoring plan for that facility and usually
includes surface water monitoring, but again the plan may include top, mid bottom, sediment, fish tissue
sampling.... depends on the specific plan for that permit. The plans are approved annually by the Environmental

Dear Mr. Sideris:
The Division of Water Quality (the Division) has reviewed your request to add a reverse osmosis (RO) water
treatment system to the subject facility. Your request is hereby granted and is effective immediately. Please
insert the attached change -pages into your existing permit and discard the old pages.
We understand that you propose to discharge RO wastes as `low -volume wastes" via internal Outfall 002,
ultimately to Hyco Lake via final Outfall 003. Based on your reported flow at Outfall 003 (1,066 MGD) and
your proposed RO volume (0.360 MGD), the Division estimates that this new waste constitutes 0.034 % of your
average daily discharge to the natural environment.
Considering the proposed volume and concentrations of RO parameters of concern, the Division judges the
potential impact to the environment to be insignificant. Therefore, per your request received May 22, 2009, we
have added reference to the new RO system on the permit Supplement to Cover Sheet, but have made no
additional changes to the permit.
The Division of Water Quality issues this permit modification pursuant to the requirements of North Carolina
General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Environmental Protection Agency'dated October 2007, or as subsequently amended. All active permit
parameters and monitoring conditions remain in effect. If you have questions or concerns about this
modification, please email Joe Corpomn jjoe.corporon®ncdenr.gov], or call [phone].

Section D Summary of Findings /Comments
1. Permit:
Your NPDES Individual Wastewater permit became effective July 1, 2009 and expired on
March 31, 2012. The facility is not currently under a Special Order by Consent.
The facility was compliant with the wastewater requirements of the NPDES permit the day of
the inspection. The application for permit renewal was received on October 10 2011 as
required. The new permit has vet to be re -issued by the Division of Water Resources
therefore, this inspection was conducted based on NPDES wastewater discharge permit issued
July 1. 2009 as these requirements remain in effect until the new permit is issued.
2. Compliance Schedules:
The permit does not have any outstanding compliance schedules for this facility.
3. Facility Site Review:
The overall condition of the plant site was satisfactory. The appearance of the facility was in
satisfactory condition indicating the current housekeeping practices are good.
4. Records/Reports:
a) A review of the daily monitoring data submitted during the previous 12-month period
and a review of the permit conditions indicates the facility was in compliance with the
permit requirements and/or limitations.
The facility was issued no penalty assessments and no notices of violation for the 12-
month period.
The wastewater and groundwater reports data was reviewed. One data discrepancy
was found between a Ioz book date for pH reading for Outfall 003 and date listed on
the DMR and an amended DMR was requested. According to the data entered in the
DWR BIMs system the facility has provided the groundwater monitoring results as
required by the Groundwater Monitoring Plan dated March 17 2011.
The records for the Biological Monitoring Plan reside with the Environmental Sciences
Section (DWR ESS). The facility has provided a copy of the 2012 results and is
currently completing the 2013 Monitoring Plan.

Opp
The records for the Ash Pond Dam Integrity Inspections and the NPDES Stormwater
permitting and compliance now reside with the Division ofEnerr;y Mines and Land
Resources (NC DEMLR) and were not part ofthis inspection
An Operation and Maintenance Plan and Emergency Response Plan for the bioreactor
is required. General Electric is the consultant/supplier of the Bioreactor operations
and maintenance and an Emergency Response Plan for the Roxboro Plant is inclusive
of Bioreactor operations.
b) The facility must designate a certified Operator -in -Responsible -Charge (ORC) having
a certification level equal to or greater than the facility classification. A Back-up ORC
must also be designated with a minimum certification level at least one level less than
the facility classification.
The facility is current!y in compliance with these re uirements. The Qgerator in
Responsible Charge (ORO is Eric D. Satterwhite He holds a PC-1 Wert No 996750)
and Wastewater III (Cert. 9893542The permtttee has several certified operators
designated as Back-up Operators (BORC's)
S. Self -Monitoring Program:
You are reminded that your monitoring samples must be collected, preserved, and analyzed by
appropriate procedures and methods. You should maintain records of the sampler temperature,
and a certified laboratory must calibrate the sample thermometers annually.
Your operator is reminded that he/she must keep a logbook of all operation/maintenance
activities undertaken at the facility. The logbook should include all daily process control
activities including any field measurements conducted for process control. A visitation log for
the facility must also be maintained.
The facility is currently in compliance with these requirements
6. Laboratory:
For all analytical data submitted for compliance monitoring purposes, a certified laboratory
must be utilized for all laboratory analysis. Additionally, if field parameter testing is
conducted, an operator certified to perform the specified field parameter analysis is also
required. The operator needs to be sure to calibrate all meters/instrumentation before each use
and retain all calibration records.
The facility is currently in compliance with these requirements and utilizes Pace NC
Certified Labs (different analytes are sent to different Pace locations Raleigh
Asheville....) The facility holds a current NC DWQ Laboratory Field Parameter
Certification #5080 for yHand temperature measurements.
The Regional Field Inspectors checklist (to be forwarded to the DWQ Laboratory
Certification Program) was completed the day of the inspection and reflects the extent of
laboratory items investigated by Regional inspectors Lab inspections are also performed
sWarately by the Lab Certification Program. The Re ional lab checklist results are
attached.

Shannon and LeToya,
I am finalizing the inspection report for the December Roxboro Inspection and have a
question.
We discussed the log book showing the pH reading for September 41h was placed on the
DMR for September 5th, as were all readings at outfall 003. Can you confirm if the log book
date was incorrect or if the DMR date was incorrect?
It's a small discrepancy, but I need to understand if an amended DMR will be forwarded or if
the log book entry has been corrected.
Thank you for reviewing.
Sincerely,

Subject: FW: Late/Missing GW59 ? Violation Action - None
Autumn
We did some follow up on your questions about the groundwater monitoring for the Roxboro Power Plant, and below is
some information you may want to consider:
1. When APS/CO first directed the Power Plants to put wells at their Compliance Boundary in 2010, it was directed
state-wide, and the wells were put in BIMS by the former APS/CO staff. The entry of the wells in BIMS were not
necessarily coordinated with when the wells were actually constructed or when they began sampling, and the
monitoring plan actually changed quite a bit as we coordinated these actions with Progress Energy. This may
have caused some of the issues you discussed and why BIMS reports missing data in 2011. My apologies! If you
can tell us which wells you continue to have issues with, we can probably help you nail this down.
2. The CONV wells you found recorded under the Roxboro permt were wells in the system (BIMS) that we did not
have any information on —they were transferred from the old Paradox system to BIMS and we did not know if
they had been abandoned, etc., so we left them as is. As Betty told you in an earlier email, she went ahead and
changed their status to temporarily abandoned in BIMS since we don't require sampling from them in the
permit and apparently they are causing BIMS to report violations.
3. Since late or missing data seemed to be a concern, we talked with Tom Moore with the BIMS IT staff and verified
how the system works. Hopefully I can explain this since it's pretty complicated. In the permit we give the
permittee 30 days after the month of sampling to report the data. So, for example, if they sample in November,
they have to report the data by the end of December. BIMS allows 60 days for data entry, so in this example
they would have until the end of February to enter the data; a total of 90 days after being sampled. After the 90
days, BIMS runs an automatic report whether the data was received and if it has violations. If the data is
entered after the 90 days allowed, BIMS will begin reporting if there are any violations, but will continue to
report that it was late/missing. Betty is currently checking to see if the Regions are receiving late/missing
reports for data received on time but is reported late due to late date entry. If so, we will talk with the data
entry staff for resolution.
4. 1 believe you have a good point about staff not entering the resolution for the violations reported. After we
finish our research, Jay wants me to address this with WQROS staff, specifically those NPDES permits that may
have monitoring wells. I did check with Vanessa Manuel and our groundwater monitoring data is not
electronically reported to EPA, although theyarp <rul___aubiect to a file review by EPA. Either way, staff should be
recording resolution for violations, and I don ling recorded.
That's all I have for now. If you have further questio
discuss. Or stop by and we can continue to research

Autumn,
I passed along the information we discussed this morning regarding the Roxboro plant and lack of listed violation actions
in BIMS for EPA reports to Debra Watts, Groundwater Protection Branch Supervisor. Late/Missing violations in BIMS
due to late data entry for data that has been received, but not entered by the deadline, can be addressed by entering
the appropriate comment -code in the "Action" and comments column on the Violations screen. Legitimate missing/late
reports will not require a code.
I have also changed the status of the two wells you referenced as "Missing Well" to "temporarily abandoned", with a
retroactive monitoring suspension date of 1/1/2011 in the current expired permit and the permit in review. I'm not sure
that BIMS will reevaluate the violations based on a retroactive monitoring suspension date; however future "Missing
Well" violations for those two wells should be prevented. I will check BIMS tomorrow to see if the violations have
changed retroactively.
Please let me know if I can be of further assistance regarding these issues.

Hi Autumn
Not sure what permit you are referring to —the Progress Cape Fear Power Plant is NC0003433 and the Progress Roxboro
Power Plant is NC0003425. Either way, our staff monitor both of these closely due to the highly sensitive nature of coal
plants these days. Staff involved include Betty Wilcox at the Central office and Eric Rice at the Raleigh Regional Office. I
will copy Betty Wilcox on this message and have her get back with you. You may also want to talk to Eric. Thanks!

Autumn,
I'm not sure who reviews the violations associated with the GW monitoring. Since this is a compliance/enforcement
issue, I've copied John who may be able to provide some information on your question. My recommendation is to touch
base with someone in the GW group. You may also want to touch base with Michele, to see if her group enters this data
into BIMS ... I'm not sure who inputs the data into BIMS.
Sorry, I'm not much help on this issue.

Subject: Late/Missing GW59 ? Violation Action - None
Hi Vanessa,
I was recently reviewing the BIMS data for an inspection at Roxboro Power Plant NC0003433.
Groundwater monitoring is required in the wastewater permit Condition A.9.
In reviewing this data, it shows late missing GW-59 reports Jan,Feb,March-2011, the sampling
started in April 2011.
Late missing GW-59 also show for May, June, August, Sept, Oct, Nov 201 1-the frequency for
reporting is for March June and October (ONLY Months required)since April 2011 to present.
See same pattern thru 2012 and 2013 with late missing GW reports.
Do you check these? or is this done by someone in GW at the central office? I think we
need to understand if there is a better way to set this up in BIMS so doesn't record a late
missing GW-59 in error. I copied Art - in case he knows.
3

Art, there is also a well missing (201 1-2013) data in BIMS (but has odd identifier) CONV004023
and 4397. Can this be removed or is the facility not reporting?
Just like to clean up BIMs data and confirming for the permit condition that GW monitoring
plan at Roxboro is being followed as required.
Thank you both for your time and let me know if these questions need to go to someone
else.
Sincerely,
Autumn

Subject. Review of Progress Energy, Roxboro Steam Electric Plant (NPDES Permit NC0003425):
"Proposed Biological Study Plan for 2013
Dear Mr. Mosely
Eric Reek of my staff has reviewed the proposed 2012 biological study plan for the Roxboro Steam
Electric Plant. The initial study plan was received by the Environmental Sciences Section (ESS) on
December 18m. 2012.
Based on a review of the study plan, we concur with the proposed addition of station SHHW to the
sampling program for both water chemistry and water quality programs and therefore approve this plan.
The need for this additional sampling station was detailed by Tom Thompson during a joint meeting
between Environmental Sciences Staff and Progress and Duke Energy staff on December 12`n, 2012.
If you have any questions, please do not hesitate to contact me or my staff.

Subject: Roxboro chemical trial
Autumn,
This is to confirm some information about the status of the recently approved bisulfite addition at the Roxboro site
associated with burning different coals. The bisulfite addition was to be based on the ORP of the FGD wastewater.
The ORP and other operational parameters during the test period did not reach the level at which chemical addition was
necessary therefore no follow up information will be forthcoming for the Roxboro site. There was no chemical addition
during the trial period. A report has been completed and will be submitted to you for the Mayo site in the next few
days.
Let me know if you have any questions.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The facility was compliant with the permit requirements the day of the inspection.
Inspection items completed, not covered in the standard BIMs checklist:
1) Follow up on Outfall 002 repairs and discuss schedule/detail of proposed repairs -
The flow at Outfall 002 will be pumped around to allow for the repairs. The facility reported that the flow and
monitoring at Ouffall 002 will be interrupted as a result of the repair work due to logistical and safety
concerns. The interruption in monitoring will occur coincident to maintenance and therefore would not be
considered a monitoring violation during maintenance duration end of November -December 2012. Also,
Outfall 002 is an internal outfall, permit monitoring for the NPDES Final Outfall 003 will continue as
normal.The repairs are expected to be completed by December 31, 2012.
2) Follow up on bioreactor operations & maintenance/bioreactor performance/emergency plan -
Discussed the Bioreactor Condition of the permit. The facility reported having an operation and maintenance
plan (tied closely with General Electric Service/Manufacturers recommendations. Monitoring included: pH,
ORP, COD and Molasses feed. An emergency response plan in event of an upset is required to be
maintained and available for inspection.
3)Follow up on chemical trails: Coal trials/bioreactor performance and gypsum effects/KleeNScrub-
The trial dealing with re -emission has not yet taken place. No notable changes to wastewater or gypsum
byproduct were reported as a result of the chemical trials to date.
4) Reviewed the Intake screen backwash. There is no monitoring required at this location by the current
permit. This backwash appears to be mechanical, so you would expect the discharge water quality to be
consistent with the intake lake water.

Record Keeping
Comment: The facility was in compliance with record keeping requirements and does
an excellent job with required DMR records and Monitoring Data documentation.
Effluent Pipe
Is right of way to the outfall properly maintained?
Are the receiving water free of foam other than trace amounts and other debris?
If effluent (diffuser pipes are required) are they operating properly?
Comment: All NPDES wastewater outfalls at this facility have been inspected
annually by RRO and there were no changes to note the day of this inspection. Field
inspection time (during a rainy day) was spent to view stormwater outfalls to determine
applicability for inclusion in the new permit, to confirm outfall locations, and to review the
stormwater information provided in the permit renewal application. The drainage maps
and labeling of the storm drainage system was observed. Discussed plans in event of
spills to the stormwater drainage system and observed outfalls to the heated water
discharge canal.
