ENGINEERING DIVISION <br />• Construct around staging and maintenance areas. 2001 S. state street w N3300 <br />Construct around vehicle parking and servicing areas. San 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 <br /> 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 /> <br />LIMITATIONS: ¦ Toxic Materials <br /> ? 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-stormwater discharge. o Medium Impact <br />Look for runoff bypassing ends of berms or undercutting berms. ? Low or unknown Impact <br />• Re <br />ir <br />r <br />l <br />d <br />d <br />f th <br />b <br />pa <br />o <br />rep <br />ace <br />amage <br />areas o <br />e <br />erm and remove accumulated <br />sediment. <br />• Recompact soil around berm as necessary to prevent piping.
