IC10. OUTDOOR LOAD INGIU NLOADI NG OF MATERIALS Best Management Practices (BMPs) A 8MP is a technique, measure or structural control that is used for a given set of conditions to improve the quality of the stormwater runoff in a cost effective manner. The minimum required BMPs for this activity are outlined in the box to the right implementation of pollution prevention?good housekeeping measires may reduce or eliminate the need to implement other more costly or complicated procedures. Proper employee training is key to the success of BNIP implementation. The P MPs outliner/ in this fact sheet target the following pollutants: Targeted Constituents Sediment x Nutrients x Floatable Materials ?Metals x Bacteria Oil & Grease x Organics & Toxicants x l Pesticides x Oxygen Demandin MIN[MUM BEST MANAGEMENT PRACTICES Pollution Prevention/Good Housekeepin_a • Park vehicles and conduct loading unloading oily in designated loading."'unloading areas so that spills or leaks can be contained. • Clean load inglunloading areas regularly to rernove potential sources of pollutants. • Reduce exposure of materials to rain • Use drip pans underneath hose and pipe connections and other leak-prone spots during liquid transfer operations, and when making and breaking connections. • Inspect equipment regularly. • if possible, conduct loading and unloading in dry weather, Stencil storm drains Traininc • Train employees on these BMPs, storm water discharge prohibitions, and wastewater discharge requirements. • Provide on-going employee ;raining in pollution prevention. Provided below are specific procedures associated with each of the minimum BIVIPs along with procedures for additional BIAPs that should be considered if this activity takes place at a facility located near a sensitive watemody. In order to meet the requirements for medium and high priority facilities, the owners/operators must select, install and maintain appropriate BMPs on site. Since the selection of the appropriate BMPs is a site-specific process, the types and numbers of additional BIVIPs will vary for each facility. 1. Properly design loadinglunloading areas to prevent storm water runon, runoff of spills, etc. • Grade and/or berm the area to prevent runon. • Position roof downspouts to direct stormwater away from the area. • Grade and/or berm the load inglunloading area to a drain that is connected to a dead-end. • The area where truck transfers take place should be paved. If the liquid is reactive with the asphalt, Portland cement should be used to pave the area. • Avoid placing loading 'unloading areas near storm drains. 2. Park vehicles and conduct loading/unloading only in designated loading/unloading areas so that spills or leaks can be contained. 1 Clean loadinglunloading areas regularly to remove potential sources of pollutants. This includes outside areas that are regularly covered by containers or other materials. 4. Reduce exposure of materials to rain. Cover the load inglunloading areas. If a cover is unfeasible, use overhangs, or seals or door skirts to enclose areas. 5. Use drip pans underneath hose and pipe connections and other leak-prone spots during liquid transfer operations, and when making and breaking connections. i EPA " Prelrmrmary Data Summary of Urban Stormwater Best Management Practices" RAO i nlu<<cittnt c>E' 4l ,iritil 20D-28
