guidance - INSTRUCTIONS FOR SAMPLE HAZARDOUS WASTE TANK SYSTEM DAILY INSPECTION LOG Instructions: This form may be used to conduct the required self-inspection of a hazardous waste tank system. The inspection by the tank system operator or owner is required on a daily basis pursuant to the California Code of Regulations (CCR), Title 22, section 66265.195. Generators of hazardous waste that are large quantity generators or onsite waste treatment operations using a tank system to manage waste are required to conduct these inspections. The tank system inspection records are required to be onsite, available for inspector review, and kept for at least three years. If the tank system or a component of the tank system(i.e. piping,pumps, valves, secondary containment, sump, etc.) is in poor condition or unfit for service, the tank system operator must take proactive steps to investigate, repair, and/or replace the equipment,parts, or components as required in section 66265.196 of Title 22 CCR. Title 22 CCR 66265.195 Tank System Inspections (a) The owner or operator shall inspect,where present, at least once each operating day: (1) overfill/spill control equipment(e.g., waste-feed cutoff systems, bypass systems, and drainage systems)to ensure that it is in good working order; (2) the aboveground portions of the tank system, if any, to detect corrosion or releases of waste; (3) data gathered from monitoring equipment and leak-detection equipment, (e.g., pressure and temperature gauges, monitoring wells)to ensure that the tank system is being operated according to its design; (4) the construction materials and the area immediately surrounding the externally accessible portion of the tank system including secondary containment structures (e.g., dikes) to detect erosion or signs of releases of hazardous waste (e.g., wet spots, dead vegetation); and (5) for uncovered tanks, the level of waste in the tank, to ensure compliance with section 66265.194(b)(3). (b) The owner or operator shall inspect cathodic protection systems, if present, according to, at a minimum, the following schedule to ensure that they are functioning properly: (1) the proper operation of the cathodic protection system shall be confirmed within six months after initial installation, and annually thereafter; and (2) all sources of impressed current shall be inspected and/or tested, as appropriate, at least bimonthly (i.e., every other month). (c) The owner or operator shall document in the operating record of the facility an inspection of those items in subsections (a) and(b) of this section. 23
