Subject: Dan River Combined Cycle-Updated List of Chemicals
Amendment to existing NPDES permit
NC0003468
Rockingham County
Dear Dr. Chernikov,
As requested and approved previously at our Dan River Combined Cycle in July 2016, Duke Energy
(Duke) submits this letter to amend our existing NPDES permit under which the plant currently operates.
The amendment is to add lime to the list of Potential Discharges Not Covered by Analysis required by
Form 2C-Item VI. An updated list of chemicals is attached. Please include this with the relevant permit
files.
Lime will be used for conditioning and dewatering coal combustion residuals stored in the primary and
secondary ash basins prior to transfer to onsite landfill.
It is our understanding that with this modification to the existing permit application, no permit
modification would be necessary and Duke is authorized to utilize these additives to assure compliance
with NPDES permit limits and keep the dewatering system operational.
If you have any questions regarding this letter, please contact Joyce Dishmon at 336-623-0238 or
[e-mail].
I certify under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the
information, the information submitted is, to the best of my knowledge and belief true, accurate,
and complete. I am aware that there are significant penalties for submitting false information,
including the possibility of fines and imprisonment for knowing violations
Sincerely,

produce steam and pressure
Extinguishing Media: Use dry chemical fire extinguisher. Do not use water or halogenated compounds,except
that large amounts of water may be used to deluge small quantities of lime kiln dust. Use appropriate
extinguishing media for surrounding fire conditions.
Fire Fighting Instructions: Keep personnel away from and upwind of fire. Wear full fire-fighting turn-out gear(full
Bunker gear),and respiratory protection (self-contained breathing apparatus.
SECTION 6.Accidental Release Measures
Individual and collective precautions: Avoid creating conditions which release dust—use
mechanical vacuums to remove dust from work spaces.
Avoid inhalation of Dust: Wear respiratory protection—minimum NIOSH N-95 Dust Mask.
Cleaning methods(Leaks&Spills): Use personal protective equipment(eyes,skin and inhalation,see Section 8).
Use dry methods(vacuuming, sweeping)to collect spilled materials. Avoid generating dust. For large spills,
evacuate area downwind of clean-up area operations to minimize dust exposure. For small spills,store spilled
materials in dry,sealed plastic or metal containers. Dust residue on surfaces may be washed with water.

5. Fire Fighting Measures
Suitable(and unsuitable) Use dry chemical fire extinguisher. Do not use water or halogenated
fire extinguishing media: compounds,except that large amounts of water may be used to deluge small
quantities of this product.
Specific hazards arising Inhalation, skin or eye contact, can result in serious injury. This product is
from the product not combustible or flammable. However,this product reacts violently with
water, and can release heat sufficient to ignite combustible materials. This
product is not considered to be an explosion hazard, although reaction with
water or other incompatible materials may rupture containers. When this
product is wet, it can be very slippery and can result in a slip hazard.
Hazardous Combustion Products: None.
Special protective Wear full fire-fighting turn-out gear(full Bunker gear),and respiratory
equipment and protection (SCBA)to prevent inhalation, skin or eye contact.
precautions for fire
fighters
6. Accidental Release Measures
Personal precautions, protective equipment,emergency procedures:
Avoid inhalation,eye and skin contact. Avoid generating airborne dust. Wear appropriate
protective clothing as described in section 8.
Methods and materials for containment and clean up:
Utilize cleanup methods that minimize generating dust:vacuum. Avoid dry sweeping. Do not use
water on large spills,as this product reacts violently with water and releases heat. Residue on
surfaces may be removed with copious amount of water or vinegar.
7. Handling&Storage
Safe Handling: Avoid inhalation, skin and eye contact. Avoid generating airborne dust. An eye wash
station should be readily available when this product is handled.
Safe Storage: Keep in tightly closed containers. Protect containers from physical damage. Store in a
cool, dry,and well-ventilated location. Do not store near incompatible materials (see
Section 10 below). Keep away from moisture. Long-term storage in aluminum
containers is not recommended, as calcium oxide may corrode aluminum over long
periods of time
