U S x.99 I <br />Dear Kathryn: iV~i~,:.'_ _~.~ <br />'EC~3ii16.i~0~' ~q" 5~~:` <br />Re: Revered Spill Plan (NPDES Permit No. CO-0032115) <br />As per my letter of 6/19/91, Trapper submitted to the Division a revised Spill Prevention Control and Coun- <br />termeasure (SPCC) plan on May 31, 1990. That document updated aB changes since our original SPCC <br />plan was submitted in 1981. <br />There have been no major changes since May 1990. T4is correspondence is to update a very minor change <br />that shall occur this year. Trapper is adding an aboveground blasting emulsion tank to its stored quantities <br />list (page 4, SPCC Plan). This 10,500-gallon tank is currently ktcated in B pit (Site 6) but wiB be moved as <br />this pit closes in late 1992 or early 1993 and blasting requirements change. Adequate berms will be <br />constructed as described in 122.7(3), to contain any potential spill. A revised page 4 is attached. <br />A revised SPCC map (M57 sheet 1 of 2) is alto enclosed. <br />Trapper it currenty relocating an underground natural gas pipeline in our shop/erection area. <br />Please contact me if you should have questions or would comment regarding these minor revisions. <br />Sincerely, <br />William Agnew <br />Sr. Environmental Engineer <br />WSH\ WA\jsb <br />~SEPT04j <br />III IIIIIIIIIIIIIIII <br />999 <br />Enclosure <br />J.M.
