IAF Glass Libbey-Owens-Ford Company April 3, 1986 Mr .Jim Eckman , Project Engineer CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD CENTRAL VALLEY REGION 3201 S Street Sacramento, California 95816-7090 APR 7 196 Dear Mr . Eckman : ENVIEEkOMMM11rrEN7AL HEALTH In response to Your letter and inspection report ofRZ �8JR)aCEN March respectively and to confirm our telephone conversation of April 2, 1986 we would like to make the following points: 1 . To clarify the data concerning the volumes of oil believed lost , we have previously reported 9,000 gallons for the January, 1985 spill of which 6051 gallons have been recovered. The February 23rd tank overflow could have been as much as 4113 gallons but was most likely less. We recovered 2650 gallons and believe most of the rest was removed with the soil . 2. We believe the oil remaining in the soil under the tanks is probably not from the February spill but an accumulation of years of poor housekeeping and the draining of small amounts of water from the bottom of the tanks. This practice was stopped several years ago. 3. We are deeply concerned about the possible release of this accumulated oil to the water table and agree with you that the extent of the contamination should be immediately defined. To this end we have requested Woodward-Clyde Consultants to put together a program which will include whatever is necessary to determine the extent of oil in the soil and ground water . We will be available to discuss their proposals with you the week of April 28th and upon your approval to begin drillings or excavations by June 2, 1986. 4. Woodward-Clyde will also be analyzing the remobilizing of the oil due to the fluctuating ground water level at the January 185 spill site. We have discussed with them in detail your suggestions and proposals to flush the oil from the soil . We agree with you that a new program is needed and must be implemented as soon as possible to either remove the oil from the soil or to somehow isolate the contaminated area from the environment . To this end we have requested Woodward-Clyde to develop a plan for us to accomplish these goals. We wish to discuss the details of this plan with you the week of April 28 and will implement the new technique immediately thereafter . 5. We, of course, are continuing to maintain a water table depression and are reclaiming small amounts of oil from the site. Per your suggestion we allow the level in the extraction pit to rise to a maximum on a daily basis to take advantage of the current seasonal peak in the water table to flush as much oil out 500 East Louise Lathrop,California 95330 Telephone 209 858-5151 TWX 510-762-6630
