BMP Cost and Effectiveness. The costs .of implementing BMPs vary depending <br /> upon many -factors and site-specific conditions. In general, the required baseline BMPs are <br /> relatively Iow in cost when compared with more traditional stormwater treatment or highly <br /> engineered controls. Costs also vary depending upon the size of the facility, the number of <br /> employees, the types of chemicals or raw materials stored or used, and the nature of plant <br /> + operations. However, because many of the baseline practices are widely accepted and considered <br /> "common sense" or standard good operating practices, many facilities have them in place. <br /> 6.1.2. Reduce, Reuse, Recycle. United States Environmental Protection Agency <br /> (USEPA) encourages industrial facilities to choose practices that,prevent the contamination of <br /> stormwater .rather than treat it once it is polluted. Use of the Storm Water Management r <br /> Hierarchy, as listed in the table below, was used to select BMPs for this program. <br /> USEPA recommends that practices be chosen that eliminate or reduce the amount of <br /> pollutants generated on the. site. This practice is referred to as "source reduction". Options that <br /> recycle or reuse-the stormwater in your industrial processes, or those that reduce the need to store <br /> and expose more hazardous materials to stormwater by recycling or recovering used materials <br /> were considered. Treating stormwater to remove pollutants before they leave the site is the next <br /> best option, although this often just transfers the problem from one place to another. <br /> I' <br /> CLASSIFICATION OF STORMWATER BMPs <br /> Stormwater Management Hierarch Example-BMPs <br /> Source.Reduction ♦ Preventive maintenance <br /> ♦ Spill Prevention <br /> ♦ Chemical substitution <br /> ♦ Housekeeping <br /> ♦ Training <br /> �I, ♦ Materials management practices <br /> Containment/Diversion ♦ Segregating the activity of concern 4 <br /> ♦ Covering the activity <br /> ♦ Berm'ing the activity <br /> ♦ Diverting flow to grassed area <br /> ♦ Dust control <br /> {i Recycling ♦ Recycling <br /> Treatment ♦ Oil/water separator t <br /> ♦ Vegetated swale <br /> ♦ Stormwater detention pond <br /> 6.2.
