Metal Mining SWMP Guidance Document <br /> Page 6 <br /> well as maintenance of equipment and systems to prevent conditions that could cause <br /> breakdowns or failures resulting in discharges of pollutants to surface waters. <br /> This part of the SWMP should also include maintenance of the BMPs which are discussed in Part 5.f. Set up a <br /> schedule appropriate to the activity and the BMP. Preventive maintenance should be coupled with periodic <br /> inspections. If there are already inspections/preventive maintenance programs or practices or equipment in <br /> place, include them here. <br /> Preventive maintenance involves the regular inspection and testing of plant equipment, operational systems and <br /> drainage systems. These inspections should uncover conditions, such as cracks or slow leaks, which could <br /> cause breakdowns or failures that result in discharge of pollutants to storm sewers and surface waters. The <br /> program should prevent breakdowns and failures by adjustment, repair or replacement of equipment. An <br /> effective preventive maintenance program should include the following elements, at a minimum: <br /> identification of equipment, systems, and facility areas that should be inspected <br /> schedule for periodic inspection or testing of this equipment and systems. <br /> appropriate and timely adjustment, repair or replacement of equipment and systems. <br /> maintenance of complete records on inspections, equipment, and systems <br /> a program for stocking spare parts critical to the operation of equipment (e.g., fuel pumps, etc.) <br /> In order to adequately define a preventive maintenance program, review the information gathered so far in <br /> terms of materials handling, risk assessment, etc., to determine where equipment failure could result in spills or <br /> leaks of contaminants. This section will be highly specific to each facility. However, as appropriate, the <br /> following items should be included in the program: <br /> pipes - pressure vessels <br /> - above ground pressure release valves <br /> - below ground oil/water separators <br /> storage tanks and bins pumps <br /> - chemical storage - fuel pumps <br /> - fuel farms - sump pumps <br /> -underground storage tanks - other <br /> -used oil storage tanks - material handling equipment <br /> - garbage/trash bins <br /> stormwater management devices <br /> - detention pond maintenance <br /> - vegetation removal <br /> - removal of sediment from storm drainage systems, including roadside ditches <br /> - checking to see that drain inlets are not clogged by debris <br /> - verification that chemical containment areas are not filled with snow or water <br /> d. Good Housekeeping - The SWMP shall identify good housekeeping procedures that will be <br /> followed by the mining operation. Good housekeeping requires the maintenance of a clean, <br /> orderly facility. This part of the SWMP should address cleaning and maintenance schedules, <br /> trash disposal and collection practices, grounds maintenance, etc. <br />
