North American Refining {conoco) Conoco Inc. P 0. Box 37 Westlake. LA 70669 (3181 491-5211 May^f 1981 Mr. Frank Early United States Environmental Protection Agency National Enforcement Investigations Center Box 25207 Denver, CO 80225 Dear Mr. Early: During the inspection of Conoco Inc.'s Lake Charles Refinery earlier this year, you requested additional information. The following information is included in this report: a) Refinery acreage b) Data on previous priority pollutant sampling c) List of products MCD 000002645 d) Updated list of storagevessels e) Map of emission sources During your visit you requested the acreage of the refinery. The follow ing acreages were estimated from plot pJans. No specific surveys were performed to determine these acreages. 1) Acreage of operating units - 34.89 acres. 2) Acreage of tank farms including marine dock - 200 acres. The attached Table B1 is a summary of previous results done for priority pollutant screening. The sample was taken from the refinery's lagoon effluent (outfall 001). The purpose of the test was for screening and to train personnel on sampling protocol. A list of products produced is shown on the attached Table I. Table II lists the fixed roof tanks in the refinery and Table III lists the float ing roof tanks in the refinery. Pressure storage vessels are not listed on these tables. Mr. Frank Early Page 2 May 5, 1981 Conoco drawing number LC-85-00-81-42.1-AD is attached. It shows the location of all active point sources of air emissions. Final review of the photographs taken during the inspection is not com plete at this time. If there is any other information that you need, please let me know. Sincerely, Senior Engineer Lake Charles Refinery jw Encs CC l IFW JWL AJN DTE ME0 K. C. Hunt, M. Afden - Ponca City B.
