,AEMORANDUM CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD - CENTRAL VALLEY REGION 3443 Routier Road Phone: (916) 361-5600 Sacramento, CA 95827-3098 ATSS: 8-495-5600 TO: Greg Vaughn Senior Engineer RCRA/TPCA Unit FROM: Pat Leary Associate Engineer RCRA/TPCA Unit 414- SUBJECT: ARCADY OIL COMPANY/ SOUTHERN PACIFIC PIPELINE MEE ING On 6 August 1987 we sent a letter to Arcady Oil Company setting several deadlines for compliance with the Toxic Pits Cleanup Act (TPCA) and Calderon legislation. In response to our letter, Gene Nunnelly, with Condor Environmental Management, the new consultant for Arcady, asked for a meeting with all the involved parties. Representatives of Arcady Oil Company, Southern Pacific Pipelines Inc. (SPPL), and their consultants met with representatives of the Regional Board on 17 August 1987 at 10:00 A.M. A list of those in attendence is attached. The purpose of the meeting was to establish a coordinated approach to dealing with the Arcady site closure and the SPPL gas spill investigation, since required work by both parties overlaps. Chris Nardi, consultant with the Mark Group, gave an update on the SPPL investigation work conducted to date. They have completed 14 borings in the northern half of the Arcady site, and converted three borings into monitoring wells. They have preliminary soil sample results, and expected to sample the wells that week. A report was expected to be completed in 4-6 weeks (14-28 September 1987), which will include well sample results. They are evaluating the feasibility of taking borings offsite, downgradient of the Arcady site, to completely define the extent of the plume from the gasoline spill. Gene Nunnelly spoke regarding Arcady's plans. They are currently reviewing the old Arcady data and coordinating with SPPL to determine where they believe additional site characterization work is needed. He stated that they would work with us along the way, such that an approved waste characterization plan should be completed by 1 October 1987. They indicated our 21 August 1987 deadline is not feasible given the time it will take to get organized to approach the overall investigation coordinated with SPPL. In the long run, both Arcady and SPPL felt the coordination will shorten the required time to conduct work at the site. I told Arcady that we set the 21 August 1987 deadline to keep in a timeframe such that a Hydrogeologic Assessment Report (HAR), required under the TPCA might be completed by the statutory deadline of 1 January 1988. By delaying the waste characterization, I DATE: 27 August 1987 SIGNATURE:
