STATE OF CALIFORNIA PETE WILSON, Governor <br /> CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD— <br /> CENTRAL VALLEY REGION -- <br /> 3443 ROUTIER ROAD, SUITE A <br /> SACRAMENTO, CA 95827-3098 <br /> PHONE: (916) 361-5600 <br /> FAX: (916) 361-5686 <br /> 5 � <br /> 28 February 1991 ' <br /> MAR 4 in'N <br /> Mr. Lecil M. Colburn, Director <br /> Environmental Affairs Department <br /> Jim Walter Corporation <br /> P.O. Box 31075 <br /> Tampa, Florida 33631-3075 <br /> CHARACTERIZATION OF CELOTEX WASTES FOR DISPOSAL AT THE CORRAL <br /> HOLLOW CLASS III LANDFILL, SAN JOAQUIN CO (CASE NO. 1896) <br /> This letter is in response to your 20 February 1991 submittal of analytical data on a <br /> single sample of Celotex waste. This latest submittal does not address all of the issues <br /> raised in our 7 November and 19 November 1990 letters to you regarding the subject <br /> waste stream. As such, Regional Water Board staff is unable to evaluate the <br /> appropriateness of the disposal of Celotex waste at the Corral Hollow Landfill. <br /> 1) Our 19 November letter requested that you provide calculations of Soluble <br /> Designated Levels for waste constituents of concern. Since your submittal failed <br /> to do so, the following Soluble Designated Levels, calculated using the guidance <br /> materials attached to our letter, will be used to evaluate the Celotex waste: <br /> Waste Constituent Sol. D. L. Water Quality Goal <br /> Lead 0.5 mg/l Primary Drinking Water Std. (MCL) <br /> Chloroform 0.023 mg/l Prop. 65 Regulatory Level <br /> Trichlorofluoromethane 0.75 mg/l Primary Drinking Water Std. (MCL) <br /> These values assume a 100-fold attenuation and a 10-fold dilution (for WET <br /> extracts used in the analysis of lead) or a 20-fold dilution (for TCLP extracts used <br /> in the analysis of volatile organic constituents). The 100-fold default attenuation <br /> factor is being used due to the absence in your submittal of a justification for a <br /> higher attenuation factor, as requested in our letter of 19 November 1990. <br /> 2) Some analytical detection limits contained in your submittal are higher than <br /> required in our 19 November 1990 letter and are higher than required for a <br /> determination of the potential for water quality threat. <br /> The lead result contained in your latest submittal (Anlab analytical sheet dated 5 <br /> October 1990) shows a non-detect with a detection limit of 1.0 mg/1. As this value <br /> is higher than the 0.5 mg/l Soluble Designated Level and much higher than the <br /> Method Detection Limit specified by EPA for Method 7421, I telephoned Anlab to <br />
