IC9fl. fliJTDQDR LQADINGlUNLQADING QF MATERIALS <br />Best Management Practices {BMPs} <br />A 8MP is a technique, measure or structural control that is <br />used far a given set of conditions to improve the q uality of <br />the st~rmwater runaffi in a cost effective manner'. The <br />minimum required BP1IPs far this activity are outlined in the <br />box to the right Implementation of pollution <br />prevention?gaad housekeeping measJres may reduce ar <br />eliminate the need to implement ether more costly or <br />complicated procedures. Proper employee training is key <br />to the success of B149P implementation. <br />The P ts~Ps outlined in this fact sheet target the fallowing <br />pollutants: <br />Tar eted Constituents <br />,~ <br />Sediment x <br />Nutrients x <br />Floatable Materials <br />?,~etats z <br />Bacteria <br />Qil & Grease x <br />Qr antes & Toxicants x i <br />~'esticides x <br />Cx en I]emandin <br />PvtlNlh~i~iP:3 BE=ST T.~~AGEPvtENT PRACTICES <br />Pollution Preventon?Good Ftausekeepin_a <br />• Park vehicles and conduct io-aciingunloading oily i7 <br />designated ioadingtunlaading areas so that spills or <br />leaks can be contained. <br />• Clean loadinglunloading areas regularly to remove <br />potential sources of poNutants. <br />• Reduce exposure of materials to rain <br />• Use drip pans underneatf: hose and pipe <br />connections and other leak-prune spots during liquid <br />transfer operations, and when making and breaking <br />connections. <br />• Inspect equipment regularly. <br />• if possible, conduct loading and unloacing in dry <br />aveather. <br />Stencil storm drains <br />Trainir~c <br />• Train ~ertnplcyees on these Bt.~Ps, stern ~~tater <br />discharge proi;ibitions, and ~~rastewater discharge <br />requirements. <br />• Provide on-going employee ;raining in pollution <br />prevention. <br />Provided below are specific procedures associated with each afi the minimum BPt~Ps along with procedures <br />for additional BfvtPs that should be considered if this activity takes place at a facility located near a sensitive <br />water3otly. In order to meet the requirements for medium and high priority facilities, the o~rrners,operators <br />must select, install and maintain appropriate Bf~~IPs an site. Since the selection of "the approprate ~P~9Ps is a <br />si#e-specific process, the types and numbers of additional Bh~1Ps tvili vary for each facility. <br />1. Property design toadinglunloadingareas toprevent storm water runon, runoff of spills, etc, <br />• Grade andlor berm the area to prevent runon. <br />Position reef downspouts to direct stormwater avray firom the area. <br />• Grade and~`or berm the laadingiunlaatlingarea to adrain that is connected to a dead-end. <br />The area where truck transfers take place should be paved. If the liquid is reactive with'the <br />asphalt, Portland cement should be used to pave the area. <br />Avoid placing loading'unlaading~reas near storm drains. <br />2. Park vehicles and conduct loadingluntoadingonly indesignated loadinglunloadingereas so <br />that spills or leaks can be contained. <br />3. Clean loadingluntoadtng areas regularly to remove potential sources of pollutants. This includes <br />outside areas that are regularly covered by containers or other materials. <br />4. Reduce exposure of materials to rain. <br />• Cover the loading!unlaadingereas. <br />• if a cover is unfeasible, use overhangs, or seals ar doer skirts to enclose areas:. <br />5. Use drip pans underneath base and pipe connections and other leak-prone spots during liquid <br />transfer operations. and when making and breaking connections. <br />~ ~rA" F'relrmin~ry Dana 9iemmary of dJr~a>3 Starmwater Best Nranagerr~ent Prafibces° <br />1C:lf) i ~ ,•~r,:~ ,7tin;*'§!nk><<citt~~ c>E''43~~,i~ritil <br />20D-28 <br />
