MAR 131989 <br /> CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION `i�A-1ViAL HEALTFl <br /> �JL:ii;'AJ I saw,66 <br /> ORDER NO. 89-707 <br /> CLEANUP AND ABATEMENT ORDER <br /> FOR <br /> SOUTHWEST HIDE COMPANY <br /> SAN JOAQUIN COUNTY <br /> The California Regional Water Qualitv Control Board, Central Valley Region, <br /> (hereafter Board) finds that: <br /> 1 . The Southwest Hide Company (hereafter Discharger) , owns and operates an <br /> animal hide curing facility adjacent to Highway 99 and Austin Road, near the <br /> City of Manteca. <br /> 2. Discharges from this facility are regulated under Board Order No. 80-061 that <br /> states, in part, that the discharge of wastes to ground water is prohibited. <br /> 3. The Discharger has estimated that annually 1 .65 million gallons of wastewater <br /> from the animal hide curing operations are discharged to two (2) PVC single- <br /> lined surface impoundments. <br /> 4. On 21 January 1986, the Board informed the Discharger that its brine <br /> wastewater is considered a ' designated waste' and requested a completed <br /> Report of Waste Discharge and a Technical Report pertaining to the water <br /> quality monitoring requirements of Subchapter 15, Title 23, Chapter 3, of <br /> the California Code of Regulations. <br /> 5. Over the last three years, the Board has experienced chronic difficulties <br /> in overseeing the ground water investigation at this site. Field work plans <br /> have been frequently revised. Field data is usually informally presented <br /> within reports; and data interpretation is often insufficient to determine <br /> the work components of the next phase of the ground water investigation. <br /> The result is a fragmented ground water investigation strategy with chronic <br /> delays. <br /> 6. The available groundwater monitoring data indicate that the uppermost ground <br /> water basin underlying the site has been polluted. Elevated levels ( i .e. , <br /> significant] above background) of electrical conductivity, total dissolved <br /> solids (TDS�, and chlorides have been measured in monitoring wells <br /> constructed both on- and off-site. In addition, there are indications that <br /> pollutants may have migrated downward to deeper water bearing zones. <br /> 7. Insufficient work has been performed to identify and delineate ground water <br /> pollution sources. However, recently submitted water quality data, show that <br /> the existing two surface impoundments are contributing to the site' s ground <br />
