Request for Waivers from Sampling and Testing Parameters Reissuance of VPDES Permit No. VA0052451 Virginia Power-North Anna Power Station

{

l 1

Dear Dr. Pandey :

The attached document identifles our sampling and testing obligations for the above-mentioned VPDES permit reissuance application, and details our requests for sampling and testing waivers. While some of the waivers have been previously approved, the requests are formally restated in accordance with Forms 2C,2E and 2F instructions.

Outfall 019, Domestic Water Overflow is entirely composed of groundwater used for the potable water supply. No pollutants are added to this water, and a discharge would occur only if the holding tank overflowed. We request that this outfall be deleted from the permit.

Outfalls 101 and 102 are not in use. The flash evaporator systems have been dismantled and we would like to delete these outfalls from the permit. There are no plans to reinstall this equipment or reactivate these discharges.

Outfall 114 is a new proposed outfall, Service Water Pipe Vault Drain. This new outfall will be used when leakage accumulates in the Pipe Vault adjacent to the Service Water Reservoir. Outfall 108 will be sampled to represent this outfall.

If you have any questions, please contact me at (804) 273-2985.

Sincerely, Joyce B. Livingstone Senior Environmental Specialist i

This outfall is designed to discharge continuously, but there are times, which are rare, normally during outages when no make-up water is needed and all tanks are full, when it does not discharge. It consists of reverse osmosis reject water that contains only a 3.3x concentration of constituents oflake water, and a potential residual of 0-1 ppm free chlorine from sodium hypochlorite used in the Ionics system. No l

process waste waters or pollutants from other sources are added. Also, this outfall discharges into the incoming cooling water flow just outside the intakes. The retention time < 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

This is a small area of approximately 6 acres. The only impervious area is the 0.09 acre storage building which is used for hazardous waste accumulation, with other miscellaneous storage. This storage l

building is constructed with a curbed foundation to contain any spillage and prevent any discharge i

outside the structure. Storm water collected in the higher portion to the south flows into a culvert under this storage building then discharged into Lake Anna at Outfall 023. Storm water runoff from the grassed portions of this area adjacent to the lake shore is generally sheet flow.

Storm water from the northern portion of this drainage area is conveyed under the paved roadway via two culverts. The culvert to the l

west carries the smaller amount of storm water flow which drains from open, grassed fields with no industrial activity. The culvert to the east was chosen as the sample point from Area 18 because it l

carries the collected drainage from the larger portion of the area, from the warehouse and laydown facilities, and would be more likely to contain any contaminants. Outfall 025 discharges storm water l

from this drainage into the Waste Heat Treatment Facility.
