ENGINEERING DIVISION <br />Construct around staging and maintenance areas. 2001 S. State Street #N3300 <br />• Construct around vehicle parking and servicing areas. Salt Lake City, UT 84190-4600 <br /> Tel (801) 468-2711 <br />INSTALLATION/APPLICATION CRITERIA: <br />• Construct an earthen berm down hill of the area to be controlled. The berm <br />should surround fueling facilities and maintenance areas on three sides to TARGETED POLLUTANTS <br />provide containment. <br />Berm needs to be a minimum of 1 foot tall by 1 foot wide and be compacted by ? Sediment <br />earth moving equipment. ? Nutrients <br /> ¦ Toxic Materials <br />LIMITATIONS: ? Oil & Grease <br />Not effective on steep slopes. ¦ Floatable Materials <br />• Limits access to controlled area. ? Other Construction Waste <br />Personnel need to quickly respond to spills with remedial actions. <br />MAINTENANCE: ¦ High Impact <br />Observe daily for any non-sormwater discharge. a Medium Impact <br />look for runoff bypassing ends of berms or undercutting berms. ? Low or unknown Impact <br />• R <br />i <br />epa <br />r or replace damaged areas of the berm and remove accumulated <br />sediment. <br />• Recompact soil around berm as necessary to prevent piping.
