STATE'bF CALI,'DRNIA—RESOURCES AGENCY RONALD REAGAN, Governor CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD- CENTRAL VALLEY REGION 3251 S STREET SACRAMENTO, CALIFORNIA 95816 PHONE: (916) 445-0270 28 March 1 Y Mr. J. Don Layson San Joaquin Local Health District Post Office Box 2009 Stockton, California 95201 Dear Mr. Layson: On 21 March 1972, an inspection was made of two proposed waste disposal sites in San Joaquin County. Those on the site tour were Mr. Layson, San Joaquin County; Mr. Frank Garavano and Mr. Gregory Basso of Forward, Inc. ; Mr. Alvin Franks, Senior Geologist, State Water Resources Control Board, and Mr. William Johnson, Staff Engineer, Central Valley Regional Board. The first site is south of Corral Hollow near the Alameda- San Joaquin county line, some 10 miles southwesterly of Tracy. The location, on this reconnaissance inspection, appears to have merit as a Class I site for the following reasons: 1. It is in a structural syncline which plunges in such a fashion that fluid movement controlled solely by bed- ding attitudes would move away from the nearest topo- graphic lows (stream channels) . 2. Sediments in the area consist of tightly cemented sands of non-marine to marine origin, with probable silt and clay intervals. Therefore the tendency of fluid to move across bedding planes (through permeable units) would be minimized. The tight, cemented zones would a) tend to hold fluids at the point of deposit and, b) force movement along bedding planes if migration did occur. 3. The lack of vegetation other than grasses suggests limited root-zone water. 4. The area would not degrade the esthetics because it is located well back from the main road at Corral Hollow and is hidden by a ridge of hills. 5. Winds across the area are fairly high in velocity and persistence which will aid in the evaporation process. There are some drawbacks to the site which will require study. These include:
