This intake of copper is the probable cause for the higher than normal discharge from Outfall 002. Copper condenser tubes were replaced with stainless steel tubes in 1994. 5 cind-Ladinwoh tb,„6 , _ gigNivis _ [-- i. .

However, the scope of the regulated storm water discharges at the Asheville plant is certainly less significant than what was intended to be addressed by the DWQ standard language. Any storm water program development activities at the Asheville plant would address only the new and old access roads. All other areas associated with industrial activity for the Asheville Plant drain to the ash pond which is already permitted. CP&L believes that the storm water discharge monitoring should suffice for addressing the storm water discharges from the roads. CP&L, therefore, requests that this section of the permit be deleted or significantly reduced in scope. We would be glad to meet with the DWQ staff to discuss this issue. Section A(9)—Stormwater Minimum Monitoring and Reporting Requirements ( '/ki (,4 a) • Part a. of this section allows a facility to petition for representative outfall status. The six stormwater outfalls for the Asheville Plant are substantially identical. CP&L, hereby requests that SW-3 be used for representative stormwater monitoring. • Part d. requires that monitoring results be submitted no later than January 31 for the previous year in which sampling was required to be performed. Using the example in Section A(4) above, CP&L understands that the monitoring results could be submitted no later than January 31, 2003. • Part f. (2) should contain the word "flushing" after"waterline and fire hydrant." Additionally, it is believed that"habits"should be"habitats." Part II Page 1 of 18 • DEM in item 2 needs to be replaced with DWQ. Part II Page 10 of 18 • Item 11 - Signatory Requirements, paragraph a. (1) has been modified in the Federal Regulations. This provision in the DWQ boilerplate should also be updated accordingly. 2 ri 6).1) 0, 11 ,N"b - -4 tzjaztilaitP- A-; /444)4 ;r1-taelig d'Al Division of Water Quality /5101 MEMO From: Date: To: Subject: �,t� 6nd1„e) lnhcf, S '�'�kr''l / 1,c,� f r Pa'1- -}o I 64G f L4 C( 4)W/Sw wal Gam+ I � irt, livesieille N[ ,f 4 11 l t 1 uaft&NS °re hAttt `� PIM�S Jr, P S+ CYN pro cc v1� +Iv ccefi s3 rood) el om w -Nq SwP3 ' Gv,,.. a J- S LU Audi" 144 g'o'd Cb,. ,34 WI 6t4. , Altai NCDENR North Carolina Department of Environment and Natural Resources PO Box 29535, Raleigh, North Carolina 27626-0535/Phone: 733-5083
