Easley Governor William G. Ross, Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E., Director Division of Water Quality December 13, 2005 Subject: NPDES Permit NCO039586 Harris Nuclear Plant Wake County The Division evaluated your request to consolidate stormwater outfalls sampling requirements and to allow for grab sampling instead of composite sampling for the permit renewal application. The Division agrees that outfall 003 can be used as a representative outfall for outfalls 002, 004 and Outfall 006 can be used as a representative outfall for outfalls 005 and 007. Composite samples shall be obtained as specified in 40 CFR 121.22(g)(7)(ii). Although information was submitted comparing composite samples results to grab samples results, the information is not specific for the Harris Nuclear Plant site and it is not sufficient to establish that grab samples will produce similar results to composite samples. If you have any questions please contact Teresa Rodriguez of the NPDES Unit at (919) 733-5083, extension 553. Sincerely, ./V 4��- Gil Vinzani, P. E.

Harris Nuclear Plant NPDES Permit No. NCO039586 Storm Water Sampling Dear Mr. Vinzani: SERIAL: HNP -05-142 a }. NOV 3 0 2005 As communicated in the August 30, 2005, meeting between yourself and Ms. Teresa Rodriquez of your office and Ms. Louise England and Mr. Steve Cahoon of Progress Energy Carolinas, Inc. (PEC), PEC requests to have representative outfall status given to Storm Water Outfalls 003 and 006. The Harris Nuclear Plant (HNP) has 11 storm water outfalls identified in the above referenced NPDES permit, Outfalls SW -A, SW -B, and SW -001 through SW -009. As discussed in the above referenced meeting SW -A and SW -13 are former lay down areas used during construction and therefore should not be included in storm water sampling. It was also discussed that storm water outfalls SW -001, SW -007, and'SW-008 are either partially or totally submerged under water and therefore would not yield an accurate storm water sample, SW -005 is located entirely under ground with no access to the outfall. Several outfalls remain that would produce accurate storm water samples. Outfalls SW -002, SW -003 and SW -004 drain plant yards, paved parking lots and gravel parking lots. HNP requests that Outfall 003 be a representative outfall for these three outfalls draining this area of the plant. SW -006 is located in the same area as SW -005 and SW -007 which all drain some of the same areas of industrial activity, including the fuel storage area, gravel plant yard, and the auxiliary boiler. HNP requests SW -006 be a representative outfall for these three outfalls. It is also requested that a grab sample be required for EPA Form 2F instead of grab and composite samples. Attached is a table containing grab and composite sample data for 4 different sample locations at other PEC facilities. The data demonstrates that there is no significant difference between the grab and composite samples; therefore a grab sample should be sufficient to demonstrate the quality of the storm water runoff from SW -003 and SW -006. In summary, there are several storm water outfalls at the HNP that do not include any areas of industrial activity and several outfalls that discharge under water that would not yield a representative sample. HNP is requesting that representative outfall status be issued to SW -003 and SW -006 because their discharge is similar to the remaining storm water outfalls that would Progress Energy Carolinas, Inc. Harris Nuclear Plant P. 0. Box 165 New Hill, NC 27562 Mr. Gil Vinzani SERIAL: HNP -05-142 yield representative storm water samples. It is also requested that a grab sample be required for EPA Form 2F instead of grab and composite samples.
