Subject: NPDES Stormwater Permit Hearings - Duke Energy Progress, LLC - Cape Fear Steam Electric Plant
Hearing Officers' Report and Recommendations
On February 29, 2016 1 served as hearing officer for a public hearing on the proposed issuance of a NPDES stormwater
discharge permit for the Cape Fear Steam Electric Plant, a Duke Energy Progress, LLC facility in Moncure. As hearing
officer, my main focus was to consider the public comments received during the notice period and comments given at the
public hearing in making a recommendation for final action on the draft permit. The permit under consideration and
information about the hearing is included in the table below.
Cape Fear Steam Electric Plant - Permit Number NCS000574:
This facility is located at 500 CP&L Road, Moncure, N.C. - Chatham County. The Cape Fear Steam
Electric Plant is a retired steam cycle electric generating plant that formerly operated two coal-fired units,
two heat recovery boilers and four Internal Combustion (IC) Turbines in Chatham County. The site was
retired in 2011 and is currently being decommissioned. The facility has stormwater outfalls that discharge
industrial stormwater to the Cape Fear River and to Shaddox Creek in the Cape Fear River Basin. The
hearing was held on February 29, 2016 at Central Carolina Community College in Pittsboro, NC.
There were ten attendees at the public hearing with nine of these providing verbal comments at the hearing. A summary
of the hearing is attached in Appendix B of this report. As hearing officer, I presented the hearing officer's speech at the
hearing and Bradley Bennett from the Stormwater Permitting Program provided an overview of the proposed permit. After
the overview I opened the hearing for public comment. During the public comment period we also received four additional
written comments with one of the comment letters being from the permittee, Duke Energy. Division staff have reviewed
these comments and made appropriate adjustments to the final permit where warranted.
Background
The fact sheet for the permit outlines in more detail the basis for permit coverage and permit requirements for the facility.
The facility is a former steam electric power generating facility. This industry sector is required to have NPDES permit
coverage for stormwater point source discharges from the industrial activities at such facilities. The permit documents
note that for a major portion of the industrial plant area and ash handling areas of the site, stormwater is collected and
treated in the facility's wastewater treatment system. Those drainage areas are covered in a separate wastewater
NPDES permit through the Division of Water Resources. For the areas covered by the stormwater permit, the major
provisions of the permit are requirements for a Stormwater Pollution Prevention Plan (SWPPP) for the facility, along with
monitoring (visual and quantitative) and inspection requirements. These provisions provide comprehensive coverage
through the implementation, regular evaluation and adjustment of management measures on each site to minimize the
discharge of pollutants during rainfall events.
SUMMARY OF PUBLIC COMMENTS AND RECOMMENDATIONS
As indicated above, we received comments from thirteen separate entities on the draft NPDES stormwater permit. A
summary of the public hearing comments and all written comments received are included in Appendix B of this report.
Hearing Officers' Report
February 29, 2016 Public Hearing
Cape Fear Steam Station
Staff in the Stormwater Permitting Program have reviewed the comments received and have developed responses to their
concerns. I concur with the responses and to the recommended changes in the final permit for this facility. The changes
included are minor in nature, and the final permit maintains requirements that are in line with those taken to public notice.
In the process of finalizing the permit, staff have developed transmittal letters for each permit that address the comments
and the Division's responses to these comments. The major issues raised in the comments are summarized below.
• A number of commenters expressed concerns with the self -monitoring requirements of the permit.
All permits issued under the NPDES permitting program utilize self -monitoring as a component of the permit
requirements. These monitoring results help the permittee and the state to assess potential pollutant concerns
and respond to those results. These are not, however, the only basis for control. The Division maintains
oversight of permitted facilities and performs inspections to ensure that all permit conditions are being met on
permitted sites. The agency has authority for inspections and to handle enforcement and compliance as
appropriate based on inspections. The permit's General Conditions (Part III Sect D) establish Inspection and
Entry requirements for Division personnel.
• A number of the comments received were related to concerns about seeps, discharges from the coal ash basins
at the site and groundwater impacts adjacent to the site.
We understand that these are issues of concern to commenters that participated in the process. These issues,
however, are handled by other program areas within the Department. The draft permit regulates stormwater
discharges only and does not authorize or control any wastewater or groundwater issues. Reviews of those
issues continue to be ongoing within the Department.
• Commenters also expressed concerns about the conditions of the dams associated with the coal ash ponds at the
site and asked that the Department follow all the steps necessary to repair the dams and avoid any potential
impacts.
As noted in a previous comment, the permit being considered here addresses stormwater discharges for a few
discharges from transportation areas on the project site. The Division (DEMLR) does oversee the N.C. Dam
Safety program and staff are involved with ongoing efforts to assure that dams and related structures at all Duke
facilities are in compliance and maintained properly. The Division conducts regular inspection of dam facilities
across the state and will do the same with this facility to ensure safe operation of the structure.
• Comments were received questioning the issuance of the stormwater permit while other efforts for ash pond
cleanup and excavation and disposal at the site were still being considered.
There are obviously a lot of activities currently under way at power plant sites across the state. Multiple agencies
are involved with the process and our Division continues to stay in touch with the ongoing reviews and
procedures. At this time, we feel that it is appropriate for us to move forward with the stormwater permit and get
all permit components in place and ongoing for the facility. As components of the excavation and disposal
procedures are put in place, if it becomes apparent that stormwater permit changes are needed, the Division can
pursue any needed modifications to the permit. The permit does include provisions that would require
adjustments to onsite stormwater management plans, and monitoring requirements if conditions on the site
change. The permit also requires modification in certain circumstances, such as the addition of stormwater
outfalls.
With regard to excavation and disposal the Division also notes that the stormwater permit will not authorize
stormwater discharges from areas of excavation of ash material onsite. During excavation of ash material any
drainage from the excavated areas must be handled through Duke's wastewater treatment system and not
discharged through a stormwater outfall.
• One commenter noted that the permit information outlined that a major portion of the stormwater from the site is
currently routed to the ash ponds and covered under the facility's wastewater discharge permit. The commenter
questioned what would happen when the ash ponds are closed.
Page 2
Hearing Officers' Report
February 29, 2016 Public Hearing
Cape Fear Steam Station
When final closure of the ash ponds is completed the wastewater permits and discharge may go away. At that
time, it is anticipated that the drainage areas will have been managed in an approved manner that will result in a
reclaimed area that has been stabilized and vegetated or covered in a manner where stormwater pollution issues
have been minimized. Areas meeting these criteria may no longer meet the federal requirement of being an
industrial activity and may not require stormwater permit coverage. If coverage is required for a stormwater
discharge from these areas, then the permit would have to be modified to account for any new stormwater outfall.
• A number of commenters requested that more frequent monitoring be required in the permit, some requesting
monthly monitoring.
Stormwater permits authorize discharges that are not continuous or even frequent events. Rainfall events that
lead to stormwater discharge are highly variable and inconsistent throughout the year. Requiring monthly
monitoring does not mean that there will be consistent monthly events that produce runoff discharge for sampling.
Events that do occur have to meet the criteria in the permit to be representative events and ones that can be
reasonably monitored. The Division has reviewed this request and feels that a change to automatically require
monthly monitoring is not the most effective tool for this permit. The Division understands the concerns
expressed by the commenter and feels that a minor change to the permit requirements can provide additional
monitoring data based on initial monitoring results. Initial monitoring will remain at a quarterly frequency, but the
permit has been modified to require that one exceedance, rather than two, of a benchmark value will move the
permittee forward in the permit's tiered response process that leads to monthly monitoring requirements.
• Comments were presented requesting that monitoring be done by composite monitoring rather than the required
grab samples.
The Division utilizes grab samples in all of our stormwater permitting requirements and feels that the requirement
for this sampling method at the beginning of the runoff event gives a conservative result for stormwater pollutants
leaving the site. Between storm events pollutants can be made available and build up over a contributing
drainage area. Once rainfall starts the pollutants can be picked up and carried through the drainage area to the
outfall point. Over time during a rain event pollutants can be washed off of a drainage area so that continued
monitoring may produce lower loading numbers than would be found in the initial parts of the storm event. The
permit requirement for a grab sample during the first thirty minutes of discharge should produce reasonable
information about the potential pollutant loading in the drainage area.
• Comments were received requesting that specific analysis methods be required for monitoring tests.
Part III Section D of the permit sets out testing procedures for the analysis of pollutants to assure that the
methods are consistent with state and federal regulations.
• A number of commenters raised questions about the benchmark values in the permit. Most commenters
requested that the values be lower and note health risk factors that were calculated in a different manner resulting
in lower values. Duke Energy provided comments requesting that some values be reconsidered in order to
increase the benchmark values and notes that some values may be due to background soil conditions rather than
due to an industrial activity.
Benchmarks are numerical action levels for stormwater monitoring. Benchmarks are not effluent limits.
Stormwater benchmarks are determined with help from Division of Water Resources' Classification and
Standards Unit and are determined using toxicity data from multiple sources including regulations such as EPA's
National Recommended Water Quality Criteria, the National Primary Drinking Water Regulation in 40 CFR
141.11, and NC Surface Water Quality Standards (found in 15A NCAC 02B regulations). When federal or state
regulations do not contain information for a particular pollutant of concern, benchmarks are calculated per 15A
NCAC 2B .0200 using peer -reviewed toxicity data. In general, stormwater benchmarks are calculated to mimic the
same level of protection afforded by the federal acute water quality criteria.
The DEQ follows established Federal procedures for calculation of an acute criteria when developing stormwater
benchmarks (acute standard/benchmark is set at'/2 of the calculated FAV or Final Acute Value) and, for an
additional measure of safety, typically applies those values in NPDES stormwater permits without any dilution
Page 3
Hearing Officers' Report
February 29, 2016 Public Hearing
Cape Fear Steam Station
allowance. Benchmarks based on acute criteria calculations reflect the federally approved conservative protection
level for aquatic life against negative impacts from short-term, undiluted exposure to higher levels of chemicals.
NC DEMLR believes this approach to be the most appropriate for protecting against potential impacts of
stormwater discharge exposures and consistent with DEQ's NPDES permitting program.
DEQ acknowledges that background soil containing metals may influence discharge values enough to exceed
established benchmark values for metals like copper, zinc, and possibly others that are equally ubiquitous. The
Tier Responses in the permit allow DEQ flexibility to relieve monthly monitoring if the permittee demonstrates
circumstances are appropriate (discharge levels reflect natural background or background influences beyond the
permittee's control, for example) and/or all reasonable stormwater pollution prevention measures have been
attempted but cannot bring levels down. In these instances, DEQ must also consider whether there are water
quality problems in the receiving waters resulting from these metals before making a decision on whether to grant
the permittee's request for reduced monitoring or to require additional efforts to reduce concentrations.
In the case of mercury a benchmark value such as the water quality standard of 12 ng/I is more likely to be
exceeded in stream when regional deposition is potentially driving elevated levels. This would prompt monthly
monitoring with little gain for the permittee's pollution prevention efforts. Gathering of additional data is necessary
to help determine if permit conditions should be changed. Monitoring results will be considered in conjunction
with fish tissue monitoring that is required as part of the plant's wastewater NPDES permit. These efforts, along
with reductions in air emissions, provide an additional measure of conservatism related to the bioaccumulation
potential. Language has been added to the permit to require the submittal of the fish tissue monitoring results to
the Division as a part of the stormwater permit also.
• Comments were received about the Tier Response system including that the system require stormwater
treatment and that the system require more frequent monitoring.
The Tier Response system in the permit requires that monitoring results that exceed a benchmark level result in
actions by the permittee to address these results. The permittee is responsible for determining the appropriate
response, but should include various considerations as outlined in the permit. These responses may include the
implementation of stormwater best management practices (stormwater treatment devices) for stormwater control.
As a permittee continues through the tier system, the permit outlines potential responses that may be required by
the Division including the required installation of best management practices. The Tiered system also already
required increased monitoring when benchmark levels are exceeded.
• A few commenters asked that radioactive elements be added to the monitoring requirements in the permit.
The Division feels that the information we currently have available has lead us to a reasonable suite of
parameters to assess the potential stormwater impacts for this type of facility. The Division will continue to
monitor available information on this issue, but at this time we do not feel that we have sufficient information to
add additional parameters for stormwater discharge requirements.
• A few commenters questioned the idea of Good House Keeping and Pollution Prevention as major permit
components at a site like the Cape Fear Steam Station noting that they felt these measures required pollutants to
be covered.
Good housekeeping and pollution prevention are not necessarily limited to covering pollutants at a site, thought
that is certainly an effective control method. Good housekeeping efforts may work to minimize the available
pollutants in a drainage area, change where activities occur or keep runoff from entering an area. These
measures are applicable to all sites and should be utilized to their fullest. One unique example at power plant
facilities is the extensive areas where stormwater runoff is collected from the major industrial areas and routed to
the wastewater treatment system. This approach removes these stormwater flows from the stormwater system
and provides treatment of the higher risk areas.
In addition to the items noted above I would also note that in review of the permit and comments staff also noted a few
needed changes in the permit to address areas where language needed to be clarified and to make the permit
Page 4
Hearing Officers' Report
February 29, 2016 Public Hearing
Cape Fear Steam Station
requirements consistent with current permit language for other facilities. These changes included some reference
corrections in the permit and addressing sampling outside of normal working hours.
Based on our review of the information associated with these permits, public comments received and discussions with
stormwater permitting staff, I recommend that the Director move forward to issue the final permit with the modifications
that have been included. The final permit is attached to this package for your signature.
In addition to the information contained above I would also like to provide some recommendations based on the
comments received during this process. A number of comments seemed to be concerned with ensuring oversight of the
permit conditions at the facility. Our staff in the regional office focus on the proper implementation of permits on a daily
basis so I am confident in their efforts to ensure compliance. To assist in ensuring that these efforts are handled
effectively I recommend:
1. With the issuance of this permit the Raleigh Regional Office should contact the facility to ensure that the facility
contacts are aware of the DEMLR stormwater contacts in the regional office so both parties can readily
communicate if they have questions. They should also assure that the facility makes the regional office aware in
advance of planned movement of any ash material on the site in the future. This contact should be designed to
allow the regional office to schedule an onsite visit early on in this process to review the procedures utilized and
evaluate any potential stormwater issues in the process.
2. DEMLR has multiple programs that may be involved with activities on the facility site — Stormwater, Erosion and
Sedimentation Control and Dam Safety. I'm sure that our staff already do this, but I want to ensure that as
regional staff are on site for site visits or inspections associated with any of these program areas they should also
be aware of the conditions related to other programs and be ready to assess potential issues and make
appropriate programs aware of any concerns. Our staff should also be sure to provide similar information in our
coordination with other Divisions as well.
If you have any questions, please contact me to discuss.

Nine speakers:
#1 Martha Giralami
Every time you have one of these hearings, it's a drag because we know little of what we say will be
taken into consideration. That's been our experience. Two parts today: One is what I think should be in
your permit, and two, what I think should happen at the Duke site. Mr. Bennett made an interesting
remark about "good housekeeping." That doesn't even make sense to talk about with Duke -- outdoor
manufacturing site that's had buildings blow up, pits of toxic coal ash and mismanaged over the years.
Good housekeeping happens where everything is under roof, under tight regulations. They don't
constantly put pressure on DENR to change and give them ways out. They don't have violation after
violation that's been ignored.
Please consider the following permit requirements: 1. When you have rainfalls monthly, you should be
monitoring all coal metals at all outfalls from coal ash handling areas. This must include radioactive
elements and mercury and pH. More frequent testing should be done during major rainfalls or when
releases are expected. Use a composite sampling methods, not grabs. That could be too late, too little.
If going to use grabs, use a series of grabs. 2. Do totals testing of stormwater, not a leachate test.
Instead dissolve the entire sample to determine metals content. Do not discard metal -bearing coal ash
solids as is done in the leachate procedure. These solids will remain in the environment forever and
continue to release metals. 3. Report all stormwater monitoring data to a public access website. 4. Split
samples for testing by public environmental groups if asked. 5. I think all metal benchmarks are very
high and depend on dilution to cure pollution. Benchmarks should be reduced by one tenth of FAV. In
Cape Fear, these coal ash metals will biomagnify by factors of 10,000 to 100,000 in the bodies of fish and
other animals that live in the downstream ecosystem. Biomagnification and persistence in the
environment argue for much lower benchmarks. 6. Tiered response to high benchmarks must include
treatment of stormwater before release. Adequate retention, containment, and pumping capacity must
be onsite. Stormwater treatment will require pH adjustment, mixing of coagulants and settling before
release. Any released stormwater must be tested as well. 7. Climate change is here. Weather patterns
in NC bring 25-, 50-, and 100-year storms every year. Your DEQ stormwater program should be sized
and staffed accordingly.
DEQ anticipates that demolition and closure of coal ash sites will be underway in the next couple years.
Excavation has potential for stormwater pollution into the Cape Fear River ecosystem. Public has not
been informed on excavation and disposal project. What will the coal ash work area look like? Duke
Energy must build a coal ash solidification plant onsite. Coal ash in landfills produces millions gallons of
leachates which can be reduced with solidification. Alternatively, Duke Energy could build a coal ash
reclamation plant onsite as was done in SC.
#2 Dawn Crawley
Live in Sanford, NC. I don't think this water should be discharged. There are so many toxic chemicals.
It's upstream from Lee County water intake. We already have 1,4 dioxin in our city water. My pond has
vanadium and chromium in it. They're not letting people know what's in this water. Any level of these
chemicals is no good. I have high blood pressure. They say vanadium causes high blood pressure.
These sites should be regulated by nonpartisan — not DEQ. I do not trust our government. It's the best
government money can buy. If county officials, environmental groups, riverkeepers should have free
access to these sites. People should know what's in their water. We don't want another Flint, Michigan.
Brickhaven is already dumping these chemicals into the river. If you don't have clean water and clean
air, you can't live. This will affect the whole county, counties downstream, anyone that pulls water out
of Cape Fear River. It should be frequent monitoring. Access to any groups, especially nonpartisan
groups.
#3 Shelton Bass
I'm from Lee County. We need a Flint, MI disaster to bring attention to get Duke clean this up. In the
meantime, we'll let McCrory do whatever he wants to do. This will be a disaster if you give them
permits. Let's just take a bulldozer and push the coal ash into the river. When it's raining, we'll put the
bulldozers up. Days it isn't raining, who cares? Might have been 3 million people in NC in 1969. Now
there's tens of millions in NC. Nobody cares until something happens. If you give them permits,
something's going to happen. I don't understand why you give someone a permit when you know
they'll push it into the river, into the groundwater. Duke Energy has a strong background of not caring
where it goes. Coal ash problems are coming into Moncure. Go ahead, bury the county in it. As long as
it isn't raining, do what you're going to do. Don't give them a permit. This will tie more people up in the
courts. I'm paying those judges every time I pay taxes. I've been exposed to enough of these toxic
chemicals in my life not knowing they're toxic. I found out recently I was exposed to hexavalent
chromium for years as a welder. No one tells you what's bad. Where was the government telling me it
was bad? We had dams on the rivers for flood control. In the 1970's environmentalists said these dams
are killing the fish, they can't spawn. So we took down the dams. Now we're poisoning all the water
and killing the fish. Let's just put a dam of poison in and kill all our fish. Let's take care of the people
too. Just like the dinosaurs, something else will take over when all the people are taken off this planet.
#4 John Wagner
I'm a resident of Chatham County. I worked for 3 years with GA Department of Natural Resources doing
a nonpoint source pollution study. I was on macroinvertebrate team. I'm going to ask you not to follow
NPDES rules. I'm not asking you to break the rules. I want you to follow the rules completely. I'm
asking you to do far more than just meet the minimum guidelines. I'm asking you to do everything you
can to fix and clean up Cape Fear plant's coal ash ponds. Do everything you can to make up for the
plant's incredibly bad history. It's time for you to help make up for decades of leaking metals into
waters of Chatham County. DEQ is a state agency, so why should it do more than the minimum? Five
2
reasons: First, doing minimum for decades is what brought DENR and Duke to the mess we're in now.
We've got seeps from Duke's own admissions that are leaking 3 million gallons of coal ash sludge, toxins
including lead, cadmium, vanadium, other toxins per day. We have wells across the state contaminated
by coal ash. Contamination of Cape Fear River. We've got state crisis that has resulted in a rushed and
terribly designed plan to move coal ash dumps from all over the state to new dumps with cheap plastic
liners. Second reason is because Duke and DEQ are bringing coal ash from around state to create new
dumps at Brickhaven. This has lead us to believe that DEQ to stand for "Don't Expect Quality." But we
do expect quality from you. Not just bare minimums. Three, none of the issues in the permit deal with
radioactivity. Coal ash ponds have radioactive material that needs to be included in the tests, made
available to the public. I encourage you to add that to the permit. Fourth, John Skvarla in 2013 refused
and returned EPA grant of $222,595 that had been designated to do surface water testing in the Triassic
basin. DENR disbanded the unit that applied for that grant. Tom Reeder, Director of DWQ at that time,
told Charlotte Observer Division would eliminate 70 jobs and save 4 million dollars a year that could be
used for another study. I'm asking you to use some of that money to do more than the minimum and
carry out detailed surface water studies of creeks, streams, rivers of Triassic basin, especially around
Cape Fear Plant. Four, this is DEQ's chance to correct NC's equivalent of Flint, Michigan disaster. In
2014, Associated Press said DEQ and Duke have known about contamination but failed to notify
communities. AP reported that since 2011, monitoring wells surrounding the pits have exceeded state
groundwater standards on 226 readings including for high amounts of boron, magnesium, iron, and
chromium. Residents living near were not informed of these findings. Nor did state regulators require
Duke to test for contamination on any of these properties. Chromium is a concern because in its most
toxic form, hexavalent chromium is a known carcinogen.
Do the right thing now. Require Duke to test for contamination and do your own testing. Don't just use
the TCLP that EPA has stated is outdated. Instead, use that and use more accurate LEAF test that
provides detailed detection of concentration levels of toxic metals. Now Tom Reeder's quote from N&O
11/7/2013: They didn't do a damn thing. And that's what they did. Reeder told Duke's lawyers in June
court deposition. Claiming that the risk of coal ash contamination was known to the engineers for years.
I'm just completely dumbfounded that nobody ever did anything about it, Reeder said. Everybody had
to know the extent of the harm they were doing. And why nobody would do anything about it, it's just
beyond my comprehension.
So you, DEQ, know the extent of the harm, and you have a chance to do something about it. Don't let
Tom Reeder stay dumbfounded. Do this stormwater permit right this time. Make sure our kids don't
have to deal with what's left over from this mess.
#5 Elaine Chiosso
I am Haw RiverKeeper, member of Waterkeeper Alliance. I also served on the Sedimentation Control
Commission. I currently serve on Chatham County's environmental review advisory committee. The
Haw River watershed includes Shaddox Creek which is receiving stream named in this permit. Permit
discusses that anticipated closing of coal ash ponds will result in even more stormwater pollution. But
this entire procedure is baffling to me. 4.5 million tons of coal ash sitting here contaminating
groundwater. We're looking at how Duke will control stormwater off these roads and railways lines, but
entire site is so contaminated. Not even sure what point of this is. Shouldn't state be dealing now with
the entire site? Turning it into solids would make sense. Looking at some of contaminants in coal ash as
opposed to immense amounts leaking through failing dams straight into CIF River now. This permit is
3
legitimizing this pollution. The system that's described relied on self monitoring by Duke Energy. Same
Duke Energy found in 2014 to be illegally dumping water from coal ash ponds, 61 million gallons of toxic
water straight into CF River. This was violation. This was huge, and Duke never did consider it a
problem. They thought they were doing good management. So time has gone by, we still have leaking
dams. Nothing has changed. But state plans to trust Duke Energy to carry out requirements of this
permit. What does good housekeeping mean? At a site like this, and by a company with such a poor
record. I think the more we hear, the better. What will they be monitoring for? Antimony, arsenic,
beryllium, cadmium, chromium, copper, lead, mercury, nickel, selenium, silver, boron, thallium, zinc as
well as settleable solids, pH, oils, uranium? Benchmarks in this factsheet sounds more like guidelines
rather than real regulations. They're not effluent limits with violations. Tiered system — all sounds like
gobbledygook to me. Not straightforward regulatory system that could protect us. Another example of
our state government protecting corporations instead of people. Doesn't look at receiving streams in
terms of these limits. Shaddox Creek and CF River already polluted by these contaminants. I think we
should not accept this permit and get on with the task of cleaning up these coal ash ponds.
#6 George Lucier
Chatham County resident. Former chair of Chatham County commissioners. Former associate director
of National Toxicology Program. Former chair of science advisory board for DENR for hazardous air
pollutants. Oversaw risk assessments for a number of hazardous air pollutants for the state. Some
concerns I expressed that benchmark level is confusing. Normally, that's the level at which either health
effects are determined, environmental effects, real data used to determine that. Not extrapolation.
Real data to show adverse effects occur at that level. Customary to divide that level by at least ten,
sometimes more. That doesn't seem to have been done in this case. Benchmark level has indicated
would not be protective of people or the environment. It should be at least divided by ten. Mercury is a
good example. Life cycle of mercury when emitted from coal fired power plant, goes up in air,
converted to inorganic mercury, falls to earth in waterways, microorganisms in water soil convert it to
methyl mercury, toxic form. CDC estimates that 8% of women of child bearing age have mercury levels
that put their infants, fetuses at risk for developmental neurotoxic effects. 60,000 babies born each
year with development deficit due to mercury exposure. We need to prevent additional exposure.
Other metals are like methyl mercury. Levels need to be below benchmark by tenfold. Absolute
necessity for this permit to be approved. Role of DEQ is to protect health and environment of citizens of
NC. Need to have appropriate level that can at least indicate that it's a virtual safe dose. I would urge
you to take these comments seriously.
#7 June Gallagher
You guys need a revolution in DEQ. I worked for EPA for 30 years. You need to stand up to this stuff.
Went to Perdue, environmental engineering degree. Dilution not solution to pollution. Something is
wrong in an agency that would allow a permit to be given without cleaning up the site. Everyone is
demoralized in Chatham County. I haven't read the permit. Vacuous permit. Lots of people that work
at Duke Power become soulless. I ask you to push back. With regard to treatment. Treat stuff before
you put it into water, use reverse osmosis. People around here are putting in expensive treatment
systems to treat for heavy metals. Don't think that people aren't going to go out and do some sampling.
They'll do it when you don't want to do it. Ridiculous that it's self monitoring.
#8 Diana Hales
I am a Chatham County commissioner, vice chair. I looked at your factsheet and I was struck that it is
4
similar to permit issued for the landfill at Brickhaven, which was amalgam of ideas on how to bury coal
ash. Try to not call it "landfill," "solid waste," or "hazardous waste." Called it "structural fill." We hope
it will sit where it's being dumped and not slide down from its 40-foot pyramid height into the river.
About this permit, we've heard speakers talk about it. One of the things that struck me was that
everything depends on 25-year, 24-hour storm event, 5.7 inches. I'm not sure how many inches we had
last November, but I had 6 inches at my house over two days. 5.7 inch rainfall is not realistic. Needs to
be for 100-year storm, 24-hour. 5.7 inches of rain is a drop in the bucket. That is too limiting on this
permit. I was also interested in self reporting aspect. I read legal notices in Chatham newspaper to see
when things are reported, violations for wastewater discharges, etc. This permit says an outfall would
only be monitored at one of those 25-year, 24-hour storms, but it's up to Duke to look at rain gauges
and go out and report. Then, another item that I was concerned about, the self reporting is a huge
problem. The guarantees — there's assumptions under benchmarks — assumption that permit holder will
report when hit exceedances, increasing management, monitoring. When nobody's watching, what
happens? I'm thinking that is not good management. I see what you've done away with in this permit is
notice of violations, penalties, responsibility. I've also worked at DENR, and I followed NOVs for water
quality, NPDES discharges. I found the penalty system faulty, but at least there was a penalty system.
The last thing is leaving it up to the permittee to decide what is infeasible — anything is infeasible.
Lagoon was infeasible, economically infeasible to require anything more than to dig a hole. What is
infeasible — it could be if it costs $2, 1 don't know. That is a real liability in this SPPP. They should not be
the ones to determine what's infeasible. Finally, there is also in your SPPP, you stipulate that majority of
stormwater is routed to the treatment system and those discharges are regulated by NPDES wastewater
permit. Theoretically, those ponds will be closed. Mercury monitoring — not just about the level of
mercury, but permittee can adjust at their whim. That to me is not acceptable because they should
have to have clear guidelines. This is a sliding scale. If you don't like it, you can adjust it throughout this
permit. Anything goes. Duke should be responsible. They should have numeric numbers. Should not
have a sliding scale. Bad policy. Does not protect individuals that live in these counties. I support
strengthened permit that has controls.
#9 Karen Howard
Chatham County commissioner. Sense we get is you started with result you want and work backwards to
give Duke what they want. I think they should take responsibility. They should not be regulating
themselves.

NPDES Stormwater Permit Duke Energy (DE) Cape Fear Steam Electric Plant
NPDES NO. NCS 000574
DEQ anticipates that the demolition and/or closure of the Cape Fear Site's coal ash ponds will be underway in the next few years. This excavation activity has great
potential for stormwater pollution into the Cape Fear River ecosystem. °
The public has not been informed on the excavation and disposal project for coal
ash. What will the coal ash work area look like? If DE does a bad job of this, more
stormwater pollution maybe released than ever before. In my opinion, DE must
build a coal ash solidification plant on site —blocks of coal ash grout will not release
metals to the extent that ash does. Coal ash in landfills produces millions of gallons
of leachate which can be reduced with solidification.
Alternatively, DE could build a coal ash reclamation plant together with a brick and
concrete plant on site as was done in South Carolina. Why hasn't DE done the
research necessary to solidify and reclaim coal ash —where is their superior
expertise and engineering?
Please consider the following Permit Requirements:
1. Monthly monitoring of all coal ash metals in all outfalls from coal ash
handling areas. This must include radioactive elements and Mercury and pH. More
frequent testing should be conducted during major rainfalls or when releases are
suspected. Use Gan7`Jos fq_ 5a-'cpb,"Ic no/ G�aE e;'Etlug S{-o�,w
2. The testing should be Totals testing of ormwater. Do not use a leachate
test. Instead dissolve the entire sample to determine metals content. Do not
discard metal bearing coal ash solids as is done in a leachate procedure. These
solids will remain in the environment forever and continue to release metals.
3. Report all stormwater monitoring data to a public accessed website.
4. Split samples for testing with public environmental groups if asked by these.
5. I think all of the metal Benchmarks are very high and depend on dilution to
cure pollution. Benchmarks should be reduced -- perhaps 1/10 the FAV. In the
Cape Fear River ecosystem these coal ash metals will biomagnify by factors of
10,000 to 100,000 in the bodies of fish who live in the downstream ecosystems
impacted by coal ash stormwater. Biomagnification and persistence in the
environment argue for much lower Benchmarks.
6. The Tiered response to high benchmarks must include treatment of
stormwater before release. Adequate retention containment and pumping capacity
must be on site. Stormwater treatment will require pH adjustment and the addition
and mixing of coagulants and as well as settling before release. The treated and
released stormwater must be tested as well.
7. Climate change is here or if you prefer to be a denier then weather patterns
in NC bring 25, 50, and 100 year rains to our state almost every year. Ask Greg
Fishel. Your DEQ and DE stormwater programs should be sized and staffed
accordingly.

Public Comments on the DEQ NPDES Stormwater Permit
for the Cape Fear Plant in Chatham County, NC
February 29, 2016
Good evening, and thank you for holding this public hearing on the Cape Fear
Stormwater Permit. My name is John Wagner, and I am a Chatham County resident.
I'm going to do two unusual things in my comments this evening. First, I am going to ask
you NOT to follow the NPDES rules. Second, I am going to end my comments with a
quote that I really like from Tom Reeder, the Assistant Secretary of the Department of
Environmental Quality for North Carolina.
I ask you not to follow the NPDES rules. I'm not asking you to break the rules or the law,
I want you to follow the rules and regulations totally, faithfully, and completely.
However, I'm asking you to do far more than just meet the minimal guidelines that are
set forth in the rules. I'm asking you to do everything that you can to fix, repair, and
clean up the Cape Fear plant's coal ash dumps and ponds. I'm asking that you do what
is right and what is necessary to make up for the plant's terrible history of leaks, cracked
coal ash dikes, mismanaged and partially completed repairs, and many decades of
leaking toxic heavy metals into the Shaddox Creek, Gulf Creek, the Cape Fear, and the
groundwater of Chatham County. I'm asking you to not do the bare minimum required
by law but to do what is right and what is moral.
The Department of Environmental Quality is a state agency — so why should it do any
more than the minimum to meet regulations? I'll give you 5 reasons:
1) Doing the minimum for decades is what brought Duke, DENR and now DEQ to the
mess that we are now in.
a. Seeps that leak at least 3 million gallons of coal ash water and sludge
containing toxic levels of selenium, chromium 6, lead, cadmium, vanadium,
and other toxins.
b. Wells across the state that have been contaminated by coal ash.
c. Critical contamination of the Cape Fear and other rivers including the major
Dan River spill.
d. A state crisis that has resulted in a rushed and terribly designed plan to
move dangerous coal ash dumps from all over the state to new dumps with
cheap plastic liners.
2) .. which brings me to the second reason to do more than the minimum. Duke and
DEQ are bringing coal ash from sites around the state to create new dump sites at
Brickhaven and Colon Road. At these sites, the poor planning and minimal
protections has led Lee and Chatham citizens to believe that "DEQ" to stand for
Don't Expect Quality. Granting permits that make Duke's illegal activities
permitted and therefore legal — is not protection and is not Quality. However, we
DO want quality, and we do want protections for our air and water. Show us
some real quality — not just bare minimums — in how you correct the Cape Fear
plants 5 coal ash sites.
3) Go beyond the NPDES minimal regulations because they have no mention of
testing for uranium, radium or other radioactive materials and isotopes that are
often found in coal ash. I realize that each batch of coal that was burned could
have different levels of radioactivity in the ash produced. This means that
multiple stormwater runoff sites need to be monitored, and should be monitored
monthly. Duke has not provided - any — measurements of radioactive radiation
levels. There has been no data from DEQ or Duke about this issue. DEQ needs to
do the testing and make the findings available to the public on the DEQ website.
4) In 2013, John Scavarla — head of the North Carolina Department of Natural
Resources, refused and returned an EPA grant of 222,595 dollars that had been
designated to do surface water testing in the Triassic Basin. DENR disbanded the
unit that applied for the grant. Tom Reeder, the director the Division of Water
Quality at the time told the Charlotte Observer that the division was going to
eliminate about 70 jobs and save 4 million dollars a year. He said that the money
could, in the future, be used for a water study. Some of that money should be
used NOW — above and beyond the minimal NPDES requirements. DEQ should
carry out a detailed surface water study of the creeks, stream, and rivers of the
Triassic Basin — including those that are around the Cape Fear Plant. This study
should include quarterly macroinvertebrate data, hydrocarbon data, and data on
the heavy metals in the Triassic basin surface waters.
5) This is DEQ's chance to correct North Carolina's equivalent of Flint, Michigan's
disaster. On June 171", 2014, the Associated Press released an article entitled
"Dukeville concerns over coal ash — 5 things to know". In this news release, it said
that Duke and DEQ have known about contamination but failed to notify
communities —and I quote
"Since 2011, monitoring wells surrounding the pits have exceeded state
groundwater standards on 226 readings, including for high amounts of
boron, manganese, iron and chromium. Residents living near the plant
were not informed of the findings, nor did state regulators require
Duke to test for contamination on any neighboring properties.
Chromium is of concern because in its most toxic form — hexavalent
chromium — it is a known carcinogen."
Do the right thing now, go beyond the NPDES minimal limits and require Duke to
test for contamination and do your own testing. Don't just use the old
technology known as TCLP that the EPA has stated is outdated. Use the TCLP AND
use the newer, more accurate LEAF test that provides greater detection of
concentration levels of toxic metals.
Now — Tom Reeder's quote that I promised:
This is a direct quote, word-for-word, from The News and Observer, November 7, 2015 —
an article titled "Coal Ash Troubles were Ignored for Decades in NU
"They didn't do a damn thing, that's what they did," Reeder told Duke's lawyers in
a June court deposition, saying the risks of coal ash were known to utility
engineers for years.
"I'm just completely dumbfounded that nobody ever did anything about it," Reeder
said. "Everybody had to know the extent of the harm that they were doing. And
why nobody would do anything about it — it's just beyond my comprehension."
So, you, the Department of Environmental Quality, know the extent of the harm and have
a chance to do something about it. Don't let Tom Reeder stay dumbfounded. Do what is
moral and what is right. Get Duke to clean up its mess, get Duke to do it right, thoroughly
and carefully. Use your enforcement tools make sure that these harms aren't passed to
our children and future generations. — Thank you
Cape Fear NPDES No. NCS000574 New Stormwater Permit
Written Public Comment
February 29, 2016
Dear Mr. Mike Randall,
Clean water is crucial to healthy ecosystems and communities as well as for
businesses that depend on its ready access for continual economic growth. My
concern is that the North Carolina Department of Environmental Quality is unable to
adequately conduct monitoring and the enforcement of current environmental
regulations to insure water quality. Failure to implement compliance of past
violations of state stormwater runoff rules —meant to protect our water supply —
have allowed the release of toxic [and possibly radioactive] pollutants to enter State
waters and navigable waters of the United States.
We should not disregard the many times that the five, unlined coal ash ponds at the
Cape Fear Steam Station have been cited for discharge violations, and that this
facility has earned some of the worst rankings [NC High Hazard and EPA Significant
Hazard]. In a 2013 formal letter to DENR Sec. John Skvarla, EPA noted the need for
remedial action and further studies and investigations. The unsafe conditions at all
five of the Cape Fear coal ash lagoons lead to a Poor Condition Rating for structural
dam integrity. The close proximity of these dams to the Cape Fear River poses a
constant threat to the drinking water quality of municipalities downstream from
their point of discharge. Please review detailed accounts listed in the Cape Fear
Complaint Filed document.' Preemption of this complaint by DENR in 2014 does
nothing to reassure us that the DEQ is able or willing to deal with water quality
problems of communities living near or downstream from unlined [or subsequent,
lined] coal ash waste storage sites.
This is most concerning since pollutants entering the water supply may occur from
groundwater contamination via coal ash pond wastewater seepages and from
release or discharge into surface water at Shaddox Creek and the Cape Fear River.
Since both receiving streams are classified as WS-IV [drinking water sources for
many municipalities downstream], discharge monitoring at the outfall into these
State waters is important and should be done each month. In addition, Shaddox
Creek borders the Moncure Holdings Megasite and the Charah/Green Meadows clay
mine property. Million of tons of coal ash from the Riverbend and Sutton Plant sites
are being transported through these areas, first arriving by truck and now by rail, to
lined, coal ash cell(s). Coal ash train cars run across a bridge spanning the Haw River
near Old U.S. 1. Runoff contaminants coming from any of these sites would add to
1 https://www.southernenvironment.org/uploads/audio/2014-09-03_Cape_Fear_Complaint_Filed.pdf
the cumulative level of toxic pollutants such as 1,4-dioxane, Cr+6, and mercury
presently detected in the Haw River. 2
DENR anticipates that the demolition and/or closure of the site's ash ponds may soon be underway, and
that the activity may be begun and completed within the term of the stormwater permit. We would expect
that some aspects of the ash pond closure activity may present the potential for stormwater pollution, for
example, activities such as transport of ash by rail and/or along on -site haul roads.
Cape Fear Draft Fact Sheet
When this activity begins depends on the final coal ash pond risk classification of the
Cape Fear Steam Station. Consider the near record -breaking rainfalls in NC over a 12-
day period in October of 2015 that was not related to any tropical system. Fortunately,
there were no breaches of the earthen dikes at the time but its possibility was worrisome
to the local community.
To reduce further degradation of the water quality in the Cape Fear River Basin,
consider modifying the stormwater permit to include the implementation of the
following actions:
1. Enforce full compliance of past and future violations.
2. Conduct monthly monitoring of priority pollutant metals, radioactive
elements, and pH at seepage areas, channels to Shaddox Creek and Gulf Creek and
its wetlands, and at sites above and below outfall (s) —especially during coal ash
transport operations. Repeated findings of exceedances above standard levels
should trigger more frequent monitoring.
3. Require adequate and regular training of maintenance, safety and
emergency personnel to handle contamination incidences.
4. Allow for transparency in reporting of violations and actions taken to
resolve problem(s).
Thank you for the opportunity to submit public comments for your careful
consideration.
Sincerely,
Jeannie Ambrose

Subject: Cape Fear Storm water
The five ponds at the Cape Fear Plant,are all upstream of drinking water intakes for Sanford, Dunn, Fayetteville, Wilmington,
Brunswick and Harnett counties (500,000 people). Sanford's water intake to its water treatment plant is only three miles
downstream from where the coal ash ponds are leaking or are being pumped by Duke Energy into the tributaries of the Cape
Fear River. The Cape Fear coal ash lagoon received a POOR structural condition ratings by the EPA in 2013. Since then what
has DENR (DEQ) even done for remedial action, critical study, safety updates, fixing natural corrosion? The contaminated
groundwater at Cape Fear also flows directly into the Cape Fear River. As a result, the coal ash lagoons are
also contaminating the Cape Fear River via this hydrologically connected groundwater, and thus constitute an
additional unpermitted point source discharge in violation of the Clean Water Act.
This storm water permit should be denied
• we expect them to carefully and properly fix all the issues at the Cape Fear coal ash dumps.
• we want transparency and independent verification that is available to the public that the stormwater issue are
quickly resolved
• we want them to know that there is no reason to trust ANYTHING at Brickhaven and Colon Rd - given their long
disregard for safety.
• we want monthly monitoring of:
- the existing and previous seep locations on the dams
- the canal from the Cape Fear to the Gulf Creek wetlands
- the canal from the coal ash into Shaddock Creek
- mercury levels in the canals, creeks, and Cape Fear
- the water and sediment below the Cape Fear plant (and upstream for comparison)
This is Duke and DEQ's chance to do the right thing. Duke has one of the worst coal ash safety records in the country
then it shouldn't be creating new coal ash dumps. SALTSTONE CONTAINMENT should be used
We want more than minimal compliance and what is "legal" (DEQ has permitted and made dumping the coal ash liquids into
the Cape Fear legal) - we want what is moral, what is safe, and what will protect the river and the groundwater.

Radioactive elements in coal ash must be tested for. Burning coal
concentrates the levels of radioactivity in the ash some of this ash is 50+ years old.
Duke Energy lists uranium as a possible contaminant in documents filed with the

Subject: Cape Fear Stormwater NPDES STORMWATER DISCHARGE PERMIT #NCS000574
Division of Environmental Quality,
Below are my comments regarding the issuance of a NPDES Stormwater Discharge Permit to Duke
Energy for discharge of stormwater from the Cape Fear Steam Electric Plant coal ash ponds into
Shaddox Creek and the Cape Fear River.
• In view of the long history of illegal leaking and seepage from these storage ponds into
Shaddox Creek and the Cape Fear River, periodic monitoring of parameters associated with
coal ash pond discharges (heavy metals, pH, radioactive elements) must be done in areas
close to the outflows from the storage ponds. Sediment studies should also be done to
assure that heavy metals and radioactive materials are not accumulating in the
stream/river beds.
• SDO monitoring must be done at least monthly in order to assure detection of pollutants,
which may vary widely in short periods of time based on what type of activity is
occurring at the coal ash storage site. Monitoring dates should be flexible so that they
coincide with times when contamination is most likely to occur due to activity at the site.
• All parameters must be monitored on an ongoing basis. The use of tracer elements or a
smaller suite of parameters must be prohibited. Variances in coal ash composition and
activity at the storage ponds could result in low levels of the measured parameters while
some unmeasured parameters remain high.
• Testing for levels of radioactive elements must be incorporated into the permit
requirements.
• Given Duke Energy's poor record of protecting human health and the environment, DEQ
should demand the highest level of standards from Duke Energy. Furthermore, DEQ must
monitor Duke Energy frequently on an ongoing basis, checking to be sure all guidelines are
adhered to and imposing maximum fines when any violations are found.
