Landau FROM: Gary A. Reents <br /> Senior Engineer t"'' Area Engineer <br /> DATE: 28 January 1985 SIGNATURE <br /> SUBJECT: SAMPLING AT H&M TRANSPORT, SAN JOAQUIN COUNTY <br /> On 1 October 1984, I collected one liquid and one sludge sample from the waste- <br /> water pond at the subject facility. H&M Transport is a trucking firm that pri- <br /> marily hauls molasses for use as livestock food. The facility consists of an <br /> office, truck repair shop, and truck washing area. Wastewater from the truck <br /> washing area drains to a shallow unlined pond. <br /> According to the owner, Betty Cenbrano, the truck tank trailers are rinsed at <br /> the wash facility after hauling molasses. The truck engines are also cleaned <br /> at the wash area. According to Ms. Cenbrano, no solvents are used in the <br /> washings. <br /> The pond is 150 feet by 200 feet by 2 feet deep. Large solids loading from tank <br /> trailer washings has completely filled the inlet area of the pond. Anaerobic <br /> conditions are obvious from the objectionable odors from the pond. Pond samples <br /> were collected in the approximate locations shown on the attached map. <br /> Both samples were analyzed for volatile and nonvolatile organics (EPA Methods <br /> 624 and 625) : and heavy metals. The liquid sample showed 17.6 ppb toluene and <br /> the sludge showed 4640 ppb toluene, as well as 125 ppb methylene chloride. <br /> These contaminants are most probably coming from cleaning solvents used in the <br /> washing operations. <br /> H&M Transport was requested, on 28 December 1982, and again on 4 February 1983, <br /> to file a Report of Waste Discharge. Nothing has been received to date. <br /> H&M Transport should conduct further sampling to better define the extent of <br /> the existing contamination and file a Report of Waste Discharge so that waste <br /> discharge requirements can be written to control their present discharge. <br /> The sampling plan should include sampling locations, sampling equipment, samp- <br /> ling procedures, and analytical techniques. Both the Report of Waste Discharge <br /> and the sampling plan should be prepared by an appropriate registered engineer. <br /> GAR:gs <br /> Attachment <br />
