Metal Mining SWMP Guidance Document Page 8 i containers shall be stored on pallets or similar devices to prevent corrosion of the containers, which can result when containers come in contact with moisture on the ground. all chemical substances present at the facility shall be identified. (Walk through the facility and review the purchase orders for the previous year.) all of the chemical substances used in the workplace shall be listed, and the Material Safety Data Sheet (MSDS) obtained for each. The MSDSs will be readily available for use; i.e., posted at the locations where the materials are stored and handled. -- all containers shall be labeled to show the name and type of substance, stock number, expiration date, health hazards, including reactivity, corrosivity, ignitability and toxicity, suggestions for handling, and first aid information. (This information can usually be found on the MSDS. Unlabeled chemicals and chemicals with deteriorated labels are often disposed of unnecessarily or improperly.) e. Spill Prevention and Response Procedures -Areas where potential spills can occur, and their accompanying drainage points, shall be identified clearly in the SWMP. Where appropriate, specifying material handling procedures and storage requirements in the plan should be considered. Procedures for cleaning up spills shall be identified in the plan and made available to the appropriate personnel. The necessary equipment to implement a clean-up should be available to personnel. Spills and leaks are one of the largest industrial sources of stormwater pollutants, and in most cases, are avoidable. Establishing standard operating procedures such as safety and spill prevention procedures, along with proper employee training, can reduce these accidental releases. Avoiding spills and leaks is preferable to cleaning them up after they occur, not only from an environmental standpoint, but also because spills cause increased operating costs, lower productivity, and concern for personnel safety. (Obviously, if no chemicals, fuels or other materials are stored or handled on site, the part of the SWMP dealing with potential spills is not necessary. The SWMP should then include a statement to this effect.) Many industries are required by Federal law to have a Spill Prevention Control and Countermeasures Plan (SPCC). Therefore, many facilities may already have a start on this item. It can be included in the SWMP by reference, along with a statement that the SPCC as required by other laws will be adhered to. In general, spill plans developed as part of the SWMP should contain the following: a site plan showing where materials are stored and handled, and where associated activities occur. (By including this information on the comprehensive site map required in Item B.2, a separate map can be avoided.) notification procedures to be used in the event of an accident. At the very least, the SWMP Administrator needs to be notified. Depending on the nature of the spill and the material involved, the Colo. Dept. of Public Health &Environment, local sewer authority, downstream water users, or other agencies may also need to be notified. instructions for clean-up procedures a designated person with spill response and clean-up authority. For clarity, this could be the SWMP Administrator. training of key personnel in the use of plan and clean-up procedures. signs posted at critical locations providing a summary of SPCC plan information, phone numbers, contacts, equipment locations, etc. provisions requiring spills to be cleaned up, corrective actions taken, or countermeasures implemented immediately.
