In 1987, EPA conducted s Preliminary Apeassment and Sits Inspection (•PA/SI") at the Lowry I,endf111 which had bean owned and oparstad by the CStY end County of Dapvcr since approximately 1965 ea a municipal any industrial waste disposal facility. Based on these studies and other svallegla information, the site vss included on the Suparfund National Priorities Liat on September 31, 196. Since the fall of 198<, EPA ham bean conducting the Remedial Investigation and Fvasib111ty Study ("AI/PS •) et the mite. EPA hem concluded that hazetdous ^ubstencae have been released from the site into groundwater, eurfsea water, e1 r, sediments and soil^ and that these releases may pose s threat to huWen health and the environment. It im probePla the; fhs else remedy rill not be selected for at !seer several Yesrm Ond, therefore, the tots! cost of the remedy for the mite is not yet known with cortsinty. EPA has prepared end released for PRP and public review a document entitled: Preliminary Identification of Ramodial Alternetlvam ("PIRA"). The PIRA projects the overall mi~ta remedy et Lowry to cost between $151 million and $e.6 billion. EPA hss expressed a belief that neither the least expensive nor the most expensive remedy will ba SmplamenFad. Fvr purppeaa oY prior settlement ecticne and curre0t se;ilOpant dj9Fp4/Sons, EPA has projected that the total eo@t o[ fER~LA reaPope? Oc[ionm st the Lowry landfill sits will eWe~ approximately 8500 million. EPA has identified over 365 generators, trenepo[tere, owners and operators who ate PRP9 at the Lowry tanQf111, and has attributed certain vc!umetric waste contributions to those identified pAPs based upon Snfotmet ion requests and all available documentation. .CFiI 6tee1 Corporation ("CFiI") Se considered e dII Y1DLm18 eonttibuto;-, having shipped the equivalent of 1300 gellonm o[ drummed es;amtos-contslning wastes to Lowry Lsndtill Sn 1979, Such ehipmeni for disposal wee entirely legal st the ilme and vas done Sn accordance with regulatory tequlramante. In a previous ^e:tlement, and in ongoing settlement d iscusalone with Oa mt111mia parties, EPA has used a formals Lot the calculation of a percentage share for each PRP's liability. Tha percentage ie based on the waste volume of the generator divided by the total volume of waste esiimetad to have gone to the Lowry LetMf112. 1'het percantege L^ then multiplied by the projected remedial ec.•t, aetlmeted by EPA to bs epproximetely $500 million. Using these figures, CFiI's 1,310 gallons Se divided by the latest total volume of 1i5,771,77~ gallons, with a resulting percentage of .0008351 percent. This percentage of $500 million equals 5!,137, CFiI's pro rasa share.
