APPLICATIONS: • PERIMETER CONTROL: PLACE BARRIER AT DOWNGRADE LIMITS OF DISTURBANCE. • SEDIMENT BARRIER: PLACE BARRIER AT TOE OF SLOPE OR SOIL STOCKPILE. • PROTECTION OF EXISTING WATERWAYS: PLACE BARRIER AT TOP OF STREAM BANK • INLET PROTECTION: PLACE FENCE SURROUNDING CATCH BASINS INSTALLATION/APPLICATION CRITERIA: • PLACE POSTS 6 FEET APART ON CENTER ALONG CONTOUR (OR USE PRE -ASSEMBLED UNIT) AND DRIVE 2 FEET MINIMUM INTO GROUND. EXCAVATE AN ANCHOR TRENCH IMMEDIATELY UPGRADIENT OF POSTS • SECURE WIRE MESH (14 GAGE MIN. WITH 6INCH OPENINGS) TO UPSLOPE SIDE OF POSTS. ATTACH WITH HEAVY DUTY 1 INCH LONG WIRE STAPLES, TIE WIRES OR HOG RINGS. • CUT FABRIC TO REQUIRED WIDTH, UNROLL ALONG LENGTH OF BARRIER AND DRAPE OVER BARRIER. SECURE FABRIC TO MESH WITH TWINE, STAPLES, OR SIMILAR, WITH TRAILING EDGE EXTENDING INTO ANCHOR TRENCH. • BACKFILL OVER FILTER FABRIC TO ANCHOR. LIMITATIONS: • RECOMMENDED MAXIMUM DRAINAGE AREA OF 0.5 ACRE PER 100 FEET OF FENCE. • RECOMMENDED MAXIMUM UPGRADIENT SLOPE LENGTH OF 150 FEET. • RECOMMENDED MAXIMUM UPHILL GRADE OF 2:1 (50%). • RECOMMENDED MAXIMUM FLOW RATE OF 0.5 CFS. • PONDING SHOULD NOT BE ALLOWED BEHIND FENCE. MAINTENANCE: • INSPECT IMMEDIATELY AFTER ANY RAINFALL AND AT LEAST DAILY DURING PROLONGED RAINFALL. • LOOK FOR RUNOFF BYPASSING ENDS OF BARRIERS OR UNDERCUTTING BARRIERS. • REPAIR OR REPLACE DAMAGED AREAS OF THE BARRIER AND REMOVE ACCUMULATED SEDIMENT. • REANCHOR FENCE AS NECESSARY TO PREVENT SHORTCUTTING. • REMOVE ACCUMULATED SEDIMENT WHEN IT REACHES 1/2 THE HEIGHT OF THE FENCE. SILT FENCE L J SCALE: N.T.S. LOCATE 50' FROM NEARE DRAINAGE AREA DESCRIPTION: PREVENT OR REDUCE THE DISCHARGE OF POLLUTANTS TO STORM WATER FROM CONCRETE WASTE BY CONDUCTING WASHOUT OFF -SITE, PERFORMING ON -SITE WASHOUT IN A DESIGNATED AREA, AND TRAINING EMPLOYEES AND SUBCONTRACTORS. APPLICATIONS: • THIS TECHNIQUE IS APPLICABLE TO ALL TYPES OF SITES. INSTALLATION/APPLICATION CRITERIA: • STORE DRY AND WET MATERIALS UNDER COVER, AWAY FROM DRAINAGE AREAS. • AVOID MIXING EXCESS AMOUNTS OF FRESH CONCRETE OR CEMENT ON -SITE. • PERFORM WASHOUT OF CONCRETE TRUCKS OFFSITE OR IN DESIGNATED AREAS ONLY. • DO NOT WASH OUT CONCRETE TRUCKS INTO STORM DRAINS, OPEN DITCHES, STREETS, OR STREAMS. • DO NOTALLOW EXCESS CONCRETE TO BE DUMPED ON -SITE, EXCEPT IN DESIGNATED AREAS. • WHEN WASHING CONCRETE TO REMOVE FINE PARTICLES AND EXPOSE THE AGGREGATE, AVOID CREATING RUNOFF BY DRAINING THE WATER WITHIN A BERMED OR LEVEL AREA (SEE EARTH BERM BARRIER INFORMATION SHEET.) • TRAIN EMPLOYEES AND SUBCONTRACTORS IN PROPER CONCRETE WASTE MANAGEMENT. LIMITATIONS: • OFF -SITE WASHOUT OF CONCRETE WASTES MAY NOT ALWAYS BE POSSIBLE.
