Additional Comments, Notes, or Observations

This form is 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 3 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.
