Metal Mining SWMP Guidance Document Page 7 Most facilities already adhere to some form of "Good Housekeeping" routine, whether they realize it or not. Industries must now put these practices down in writing and ensure that they are adequate to meet the needs of the facility. To prepare this section, begin by summarizing any activities which already take place, such as trash removal, oil recycling, etc. Most good housekeeping practices involve simple common sense. The basic pollution prevention concept is that a clean site will have less potential for stormwater contamination. The following checklist can serve as a starting point for the assessment of existing good housekeeping practices: are outside areas kept in a neat and orderly condition? is there evidence of drips or leaks from equipment or machinery at the site? - is garbage removed regularly? are proper clean-up procedures used for spilled materials? are there abandoned machinery, parts, etc. around the site? is every effort made to order only materials that are required, thus minimizing the amounts of materials stored? what other practices routinely performed constitute good housekeeping? (For example, are maintenance vehicles usually stored indoors?) Set up a general Good Housekeeping plan with as many of the following items as possible, plus any additional items pertinent to the site, or new ideas which are not included in the list. The Good Housekeeping plan can then be referred to later in the discussion on BMPs. The following items are typical examples of information to include in a Good Housekeeping plan: Operation and Maintenance Techniques: garbage and waste materials must be picked up and disposed of regularly. signs will be posted at appropriate locations indicating where to dispose of waste oils and refuse. locations where spill clean-up equipment and materials are stored will be appropriately marked bulletin boards with updated Good Housekeeping procedures, tips, and reminders are posted. pollution prevention concepts will be publicized through posters, newsletters, mailings, workshops, etc. fertilizers applied to landscaped areas shall be judiciously applied, using only that quantity required. The following good housekeeping BMPs are recommended methods for the storage of materials including lubricants, hydraulic fluids, vegetation maintenance materials (fertilizers, pesticides, herbicides, etc.), refuse, etc.: Material Storage and Inventory: the centralized used oil tank shall be emptied frequently enough to ensure it never reaches capacity (e.g., at least once per month). This area will be kept free of trash and spilled oil. where practical, refuse and waste storage shall take place indoors, in a safe and sanitary fashion. all refuse dumpsters and receptacles shall be equipped with functional lids to prevent precipitation from entering. -- storage containers, drums, and bags shall be stored away from direct traffic routes to prevent accidental spills. empty drums shall be covered to prevent collection of precipitation.
