Asheville Steam Electric Plant NPDES Permit Number NC0000396 Cape Fear Steam Electric Plant NPDES Permit Number NC0003433 Lee Steam Electric Plant NPDES Permit Number NC0003417 Mayo Steam Electric Plant NPDES Permit Number NCO038377 Roxboro Steam Electric Plant NPDES Permit Number NC0003425 Sutton Steam Electric Plant NPDES Permit Number NCOOO1422 Weatherspoon Steam Electric Plant NPDES Permit Number NC0005363 NPDES Permit Application Amendment Dear Mr. Vinzani: Progress Energy Carolinas, Inc. (PEC) proposes to amend the NPDES Permit application for the subject facilities to add three additional freeze conditioning agents. These facilities expect to receive shipments of coal treated with freeze conditioning agents during the winter months (November 15 through March 15). Freeze conditioning agents, needed depending upon expected weather conditions during transport to ensure coal does not freeze in railcars, will be applied at an approximate rate of 2 pints per ton of coal. The product names used by the various coal mines which supply fuel to Progress Energy Carolinas power plants could include one or more of the additional following products (MSDSs enclosed): Product Name Primary Composition FreeFlow SR -300 30 -50% glycerin Flomin ST -944 SRA > 50% diethylene glycol mixture and polymer /surfactant blend Bio -Pro 55 55% glycerin Coal pile runoff at each of these facilities flows to a treatment system (e.g., ash pond, cooling pond, settling basin). However, since there is a slight potential that these chemicals could be present in the wastewater that is ultimately discharged via a permitted outfall, PEC requests that these products be appended to the NPDES permit application. Note that toxicity testing is a permit requirement at each power plant outfall which contains the coal pile runoff waste stream. Mr. Gil Vinzani, NPDES Unit December 1, 2008 Page Two Progress Energy Carolinas, Inc., appreciates the continued cooperation demonstrated by the Division of Water Quality staff in responding to its permitting needs.
