The Regional Board has requested analyses for the specific <br /> solvents which have historically been stored in underground tanks <br /> on the Gold Bond property. Although the subject tanks are remote <br /> from the supply wells (Well No. 1 is closest at 650 feet away) , <br /> it is proposed to test for these solvents to address this <br /> concern. <br /> In summary, the recommended sampling program is as follows : <br /> "Cold Side" - EPA 601 and 606 analyses (two samples) <br /> • - Isopropyl alcohol (one sample) <br /> Isopropyl acetate (one sample) <br /> Normal propylacetate (one sample) <br /> "Hot Side" - EPA 601 (monthly for 6 months ) <br /> • The sampling of the "cold" and "hot side" reservoirs should be <br /> performed in accordance with the procedures described for trace <br /> organic materials in the EPA Handbook for Sampling and Sample <br /> Preservation of Water and Wastewater (EPA-600/4-82-029 ). In <br /> brief these procedures are as follows: <br /> • - Grab samples should be collected in a properly cleaned <br /> borosilicate glass container with screw cap and <br /> teflon/silicon septum. <br /> - Sample containers should be filled completely - no <br /> air bubbles should be present. Sealed containers <br /> should be inverted and tapped to check for air <br /> • bubbles. If air is detected, containers should be <br /> reopened and refilled. <br /> - Samples should be refrigerated to 4 degrees Centigrade <br /> after collection and prior to extraction. <br /> - For EPA 601, 624, and 625 analyses, sodium thiosulfate <br /> should be added to the empty sample container prior to <br /> • sampling if the sample will contain a chlorine <br /> residual . <br /> - Samples for EPA 601 and 624 analyses must be analyzed <br /> within 14 days of collection. <br /> - Samples for EPA 606 and 625 analyses must be extracted <br /> within 7 days and analyzed within 40 days of <br /> • collection. <br /> OIL HEATING CONDENSATE DISCHARGE <br /> • System Description <br /> Gold Bond uses both bunker oil and natural gas as fuel for its <br /> onsite power plant. The bunker oil is stored in a 210,000 gallon <br /> tank located at the southeast corner of the property (see Figure <br /> 2). Since bunker oil must be heated to approximately 160 degrees <br /> Fahrenheit to keep it in a liquid state , steam lines are run to <br /> • the bunker oil storage tank for heating. The condensate off <br /> these steam lines has historically been discharged at the ground <br /> surface adjacent to the storage tank after passage through an oil <br /> 8 <br /> • <br />
