%"W ..w (2) any changes in this document shall be approved by PHS-EHD prior to initiating work. I submitted this plan to Kasey Foley, Senior supervising REHS, for review. Also, on May 23, 1995, I re-dialed # (209)467-6735 and reached Diamond Walnut. As per operator, this number belongs to Mike Lescisin. May 30, 1995 Kasey Foley returned the Closure Plan to me with a request for a third condition. A fire permit is to be obtained prior to closure activities was added. I checked out the hazardous waste haulers registration, and called the contractor. The plan is conditionally approved. I phoned and spoke to Sherry Romero and told her status of tank removal and fees owing. Mrs. Romero said she bought the property 7 years ago (1988) and the UST was not disclosed at the time of sale. I told her she could sue former owner as the UST law was in effect in 1988. June 9, 1995 Today I performed a tank closure inspection with Ron Hiltscher, COS Fire Department. The tank excavation was re-opened by David Fisch, Contractor, and soil samples from the excavations' bottom and stockpile were obtained by Ray Azevedo, sampler from GeoAnalytical Laboratories, for unknown fuel analysis. After sampling, the stockpile was placed back into the tank excavation. (Closure Inspection 2 E) As per contractor the tank was not dry iced today, because the tank was dry iced and a 2 ft. hole was cut in it on 5-5-95. Ron Hiltscher checked the L.E.L and told me the tank was dead, and ready for hauling. Ron Hiltscher saw the 2 ft. hole in the tank, and I explained to him the removal and cutting of the tank was done without a fire permit. Ron Hiltscher spoke to David Fisch about fire permit requirements. June 20, 1995 I received and reviewed UST soil sampling results which showed a elevated stockpile lead at 190 ppm. I phoned Fisch Environmental Construction, spoke to Chris Fisch, and requested the stockpile soil be tested again with a wet test (STLC) to determine the leachable lead level. The total stockpile lead level (Pb = 190 ppm) was higher than the allowable limit of 10 times the Soluble Threshold Limit Concentration (STLC) for lead of 5 ppm. (6-9-95 laboratory results 2 F) Site follow up revealed laboratory stockpile soil sample results from STLC have not been received_ July 31, 1995 Received and discussed letter (Work Plan 2 H) and STLC results from 6-9-1995 stock pile sample (STLC 2 F) over the counter with David Fisch. Work plan stated contaminated soils will be excavated and taken to proper disposal facility. David Fisch stated lead wet test (STLC) results have been sent to PHS-EHD. (Note: STLC results on the stockpile Pb = 15.3 ppm. STLC confirms higher than allowed lead levels in stockpile soil used to back fill UST excavation.) The stockpile soils will have to be excavated from tank hole and properly disposed of prior to site clean letter. Soil excavation will not take place until David Fisch obtains approval from disposal facility. September 5, 1995 Received a call from Chris Fisch to set up the re-excavation and re-sampling inspection for September 7, 1995. 5
