FACILITY INFORMATION FACILITY ID # (Agency Use Only) - - FACILITY NAME Roz. Quik Stop Market #76 FACILITY SITE ADDRESS R03. CITY R04. 1130 South Olive Avenue Stockton, CA 95215 II. SPILL CONTROL AND CLEANUP METHODS This plan addresses unauthorized releases from UST systems and supplements the emergency response plans and procedures in the facility's Hazardous Materials Business Plan. ➢ If safe to do so, facility personnel will take immediate measures to control or stop any release (e.g., activate pump shut-off, etc.) and, if necessary, safely remove remaining hazardous material from the UST system. ➢ Any release to secondary containment will be pumped or otherwise removed within a time consistent with the ability of the secondary containment system to contain the hazardous material, but not greater than 30 calendar days, or sooner if required by the local agency. Recovered hazardous materials, unless still suitable for their intended use, will be managed as hazardous waste. Absorbent material will be used to contain and clean up manageable spills of hazardous materials. Absorbent material may be reused until it becomes too saturated to be effective. It will then be managed properly. Used absorbent material, reusable or waste, will be stored in a properly labeled and sealed container. ➢ Facility personnel will determine whether or not any water removed from secondary containment systems, or from clean-up activity, has been in contact with any hazardous material. If the water is contaminated, it will be managed as hazardous waste. If the water has a petroleum sheen (i.e., rainbow colors), it is contaminated. A thick floating petroleum layer may not necessarily display rainbow colors. Water (hazardous or non -hazardous) from sumps, spill containers, etc. will not be disposed to storm water systems. ➢ We will review secondary containment systems for possible deterioration if any of the following conditions occur: 1. Hazardous material in contact with secondary containment is not compatible with the material used for secondary containment; 2. Secondary containment is prone to damage from any equipment used to remove or clean up hazardous material collected in secondary containment; 3. Hazardous material, other than the product/waste stored in the primary containment system, is placed inside secondary containment to treat or neutralize released product/waste, and the added material or resulting material from such a combination is not compatible with secondary containment. III. SPILL CONTROL AND CLEAN-UP EQUIPMENT PERIODIC MAINTENANCE: Spill control and clean-up equipment kept permanently on-site is listed in the facility's Hazardous Materials Business Plan. This equipment is inspected at least monthly, and after each use, and supplies are replenished as needed. Defective equipment is repaired or replaced as necessary.

INDIRECT HAZARD DETERMINATION This information is required only when the presence of the hazardous substance can not be determined directly by the monitoring method used (e.g., where liquid level measurements in a tank annular space or secondary piping are used as the basis for leak determination). THE FOLLOWING STEPS WILL BE TAKEN TO DETERMINE THE PRESENCE OR ABSENCE OF HAZARDOUS SUBSTANCE IN THE SECONDARY CONTAINMENT IF MONITORING INDICATES A POSSIBLE UNAUTHORIZED RELEASE: R60. The interstices of both tanks are filled with a saturated solution of calcium chloride. The density difference between the brine (1.38 gm/cc) and groundwater (approximately 1.0 gm/cc) and/or gasoline (approximately 0.8 gm/cc) virtually precludes hazardous substance from entering the interstitial space and causing a rise in the brine reservoir. However, the appearance of brine in the primary containment indicates a leak through the primary containment wall. Likewise, a drop in brine level with no corresponding appearance in the primary containment indicates a leak through the secondary containment wall. SJCEHD-e (06/03) -1/3 06/25/03
