Section 30.515 - General Inspection(1)Inspection Requirements.(a) The owner or operator shall inspect the facility for malfunctions and deterioration of equipment or structures, operator error, and discharges, which may be causing or may lead to the release of hazardous waste constituents to the environment. The owner or operator shall conduct these inspections often enough to identify problems in time to correct them before they harm public health, safety, or welfare or the environment.(b) To ensure that they do not lead to a threat to public health, safety, or welfare, or to the environment, the owner or operator shall remedy all malfunctions, deteriorations, operator errors, and discharges which any inspection reveals. When a hazard is imminent or has already occurred, the owner or operator shall immediately notify the Department and shall immediately take remedial action.(c) The owner or operator shall record every inspection in an inspection log or summary. The owner or operator shall keep the records of each inspection for at least three years from the date of inspection or until final closure of the facility, whichever period is longer. At a minimum, these records shall include the date and time of the inspection, the name of the inspector, a notation of the observations made, and the date and nature of any repairs or other remedial actions.(2)Inspection Plan.(a) The owner or operator shall prepare a written inspection plan which shall describe the procedures which shall be carried out to comply with 310 CMR 30.515(1). Said plan shall include, at a minimum, a written schedule for inspecting monitoring equipment, safety devices, and operating and structural equipment (such as dikes and sump pumps) that are important in preventing, detecting, or responding to threats to the public health, safety, or welfare or to the environment.(b) The schedule shall identify the types of problems which shall be looked for during the inspection (e.g., inoperative sump pump, leaking fitting, eroding dike, etc.).(c) The frequency of inspection may vary for the items on the schedule. However, the frequency of inspection shall be based on the rate of possible deterioration of the equipment and the probability of a threat to public health, safety, or welfare or to the environment if the deterioration, malfunction, operator error, or discharge goes undetected between inspections. Areas subject to spills, such as loading and unloading areas, shall be inspected daily when in use. At a minimum, inspections for interim status facilities shall be in compliance with the requirements set forth or referred to in 310 CMR 7.08(4), and 30.099(6)(e) through (k), 30.099(6)(n) through (q) and 30.099(6)(u), as applicable. Inspections for facilities subject to 310 CMR 30.800 shall, at a minimum, be in compliance with 310 CMR 7.08(4), 30.606(3), 30.614, 30.624, 30.644, 30.655, 30.686, 30.692(5) and 30.696.
