This <br /> sampling plan is in response to several requests by the California Regional <br /> Water Quality Control Board (R.W.Q.C.B) for a report of waste discharge. The <br /> sampling is intended to characterize the sludge and the results used to prepare <br /> a report of waste discharge describing the most cost-effective disposal option <br /> available for your operation. <br /> The wastewater pond is approximately 200 by 150 by 2 feet deep and is <br /> located at the northwest corner of the existing facility. The H & M Transport <br /> Company also owns the land to the north and east of the wastewater pond. The <br /> pond is used to collect and hold solids and liquids obtained from washing trucks <br /> used primarily for the transport of molasses used in cattle feed. At the <br /> current time, the majority of the pond has been filled with sludge material and <br /> liquids were visable only in the far northwest corner of the pond. <br /> On October 1, 1984, Gary Reents of the R.W.Q.C.B. collected one liquid and <br /> one sludge sample from the south and east sides of the pond, respectively. The <br /> samples were analyzed for volatile and nonvolatile organics (EPA method 624 and <br /> 625, and heavy metals). The liquid sample contained approximately 0.02 parts <br /> per million toluene. The sludge sample contained 4.70 parts per million toluene <br /> as well as 0.13 parts per million methylene chloride. It was the state's opi- <br /> nion at that time that these contaminants could have come from cleaning solvents <br /> used in the washing operations. <br /> OTHER OFFICES: LEI <br /> faidield • Sacramento • Walnut Creek • Fresno • Mer<ed Reno • las Vegas • SL George, Utah <br />
