FILTER BAG CONSTRUCTION SPECIFICATIONS
1. TIGHTLY SEAL SLEEVE AROUND THE PUMP DISCHARGE HOSE WITH A STRAP OR SIMILAR DEVICE.
2. PLACE FILTER BAG ON SUITABLE BASE (E.G., MULCH, LEAF/WOOD COMPOST, WOOD CHIPS, SAND OR
STRAW BALES) LOCATED ON A LEVEL OR 5% MAX. SLOPING SURFACE. DISCHARGE TO A STABILIZED AREA.
EXTEND BASE A MIN. OF 12" FROM EDGES OF BAG.
3. CONTROL PUMPING RATE TO PREVENT EXCESSIVE PRESSURE WITHIN THE FILTER BAG IN ACCORDANCE
WITH THE MANUFACTURING RECOMMENDATIONS. AS THE BAG FILLS WITH SEDIMENT, REDUCE PUMPING
RATE.
4. REMOVE & PROPERLY DISPOSE OF FILTER BAG UPON COMPLETION OF PUMPING OPERATIONS OR AFTER
BAG HAS REACHED CAPACITY, WHICHEVER OCCURS FIRST. SPREAD THE DEWATERED SEDIMENT FROM THE
BAG IN AN APPROVED UPLAND AREA AND STABILIZE WITH SEED AND MULCH BY THE END OF THE WORK
DAY. RESTORE THE SURFACE AREA BENEATH THE BAG TO ORIGINAL CONDITION UPON REMOVAL OF THE
DEVICE.
5. USE NONWOVEN GEOTEXTILE WITH DOUBLE STITCHED SEAMS USING HIGH STRENGTH THREAD. SIZE SLEEVE
TO ACCOMMODATE A MAX. 4" DIA. PUMP DISCHARGE HOSE. THE BAG MUST BE MANUFACTURED FROM A
NONWOVEN GEOTEXTILE THAT MEETS OR EXCEEDS MIN. AVERAGE ROLL VALUES (MARV) FOR THE
FOLLOWING: GRAB TENSILE 250 LB ASTM
D-4632
PUNCTURE 150 LB ASTM D-4833
FLOW RATE 70 GAL/MIN/FT' ASTM D-4491
PERMITTIVITY (SEC-) 1.2 SEC' ASTM D-4491
UV RESISTANCE 70% STRENGTH ® 500 HOURS ASTM D-4355
APPARENT OPENING SIZE (ADS) 0.15 - 0.18 MM ASTM D-4751
SEAM STRENGTH 90% ASTM D-4632
6. REPLACE FILTER BAG IF BAG CLOGS OR HAS RIPS, TEARS OR PUNCTURES. DURING OPERATION KEEP
CONNECTION BETWEEN PUMP HOSE AND FILTER BAG WATER TIGHT. REPLACE BEDDING IF IT BECOMES
DISPLACED.

2. USE 36" MINIMUM POSTS DRIVEN 16" MINIMUM INTO GROUND NO MORE THAN 6' APART.
3. USE WOVEN SLIT FILM GEOTEXTILE AS SPECIFIED IN SECTION H-1 MATERIALS AND
FASTEN GEOTEXTILE SECURELY TO UPSLOPE SIDE OF FENCE POSTS WITH WIRE TIES OR
STAPLES AT TOP AND MID -SECTION.
4. PROVIDE MANUFACTURER CERTIFICATION TO THE AUTHORIZED REPRESENTATIVE OF THE
INSPECTION/ENFORCEMENT AUTHORITY SHOWING THAT THE GEOTEXTILE USED MEETS THE
REQUIREMENTS IN SECTION H-1 MATERIALS.
5. EMBED GEOTEXTILE A MINIMUM OF 8" VERTICALLY INTO THE GROUND. BACKFILL AND
COMPACT THE SOIL ON BOTH SIDES OF FABRIC.
6. WHERE 2 SECTIONS OF GEOTEXTILE ADJOIN: OVERLAP, TWIST AND STAPLE TO POST IN
ACCORDANCE WITH THIS DETAIL.
7. EXTEND BOTH ENDS OF THE SILT FENCE A MINIMUM OF 5' HORIZONTAL UPSLOPE AT 45
DEGREES TO THE MAIN FENCE ALIGNMENT TO PREVENT RUNOFF FROM GOING AROUND
THE ENDS.
8. REMOVE ACCUMULATED SEDIMENT AND DEBRIS WHEN BULGES DEVELOP IN SILT FENCE
OR WHEN SEDIMENT REACHES 25% OF FENCE HEIGHT. REPLACE GEOTEXTILE IF TORN. IF
UNDERMINING OCCURS, REINSTALL FENCE.

EROSION CONTROL BLANKET CONSTRUCTION SPECIFICATIONS
1. USE TEMP. SOIL STABILIZATION MATTING MADE OF DEGRADABLE (LASTS 6 MOS. MIN.) NATURAL OR
MAN-MADE FIBERS (MOSTLY ORGANIC). MAT MUST HAVE UNIFORM THICKNESS & DISTRIBUTION OF FIBERS
THROUGHOUT & BE SMOLDER RESISTANT. CHEMICALS USED IN THE MAT MUST BE NON -LEACHING &
NON -TOXIC TO VEGETATION & SEED GERMINATION & NON-INJUROUS TO THE SKIN. IF PRESENT, NETTING
MUST BE EXTRUDED PLASTIC WITH A MAX MESH OPENING OF 2"x2" & SUFFICIENTLY BONDED OR SEWN ON
2" CENTERS ALONG LONGITUDINAL AXIS OF THE MATERIAL TO PREVENT SEPARATION OF THE NET FROM THE
PARENT MATERIAL.
2. SECURE MATTING USING STEEL STAPLES, WOOD STAKE OR BIODEGRADABLE EQUIVALENT. STAPLES MUST BE
"U" OR "T" SHAPED STEEL WIRE HAVING A MIN. GAUGE OF NO. 11 AND NO. 8 RESPECTIVELY "U" SHAPED
STAPLES MUST AVERAGE 1" TO 1-1/2" WIDE & BE A MIN. 6" LONG. 'T" SHAPED STAPES MUST HAVE A
MIN. 8" MAIN LEG, A MIN. 1" SECONDARY LEG, & A MIN. 4" HEAD. WOOD STAKES MUST BE ROUGH -SAWN
HARDWOOD, 12" TO 24" IN LENGTH, 1" x 3" IN CROSS SECTION & WEDGE SHAPED AT THE BOTTOM.
3. PERFORM FINAL GRADING, TOPSOIL APPLICATION, SEEDBED PREP. & PERMANENT SEEDING IN ACCORDANCE
WITH SPECS. PLACE MATTING WITHIN 48 HRS OF COMPLETING SEEDING OPERATIONS UNLESS END OF
WORKDAY STABILIZATION IS SPECIFIED ON THE APPROVED EROSION & SEDIMENT CONTROL PLAN.
4. UNROLL MATTING DOWN SLOPE. LAY MAT SMOOTHLY & FIRMLY UPON THE SEEDED SURFACE. AVOID
STRETCHING THE MATTING.
5. OVERLAP OR ABUT ROLL EDGES PER MANUFACTURING RECOMMENDATIONS. OVERLAP ROLL ENDS BY 6"
(MIN.) WITH THE UPSLOPE MAT OVERLAPPING ON TOP OF THE DOWNSLOPE MAT.
6. KEY IN THE UPSLOPE END OF MAT 6" (MIN.) BY DIGGING A TRENCH, PLACING THE MATTING ROLL END IN
THE TRENCH, STAPLING THE MAT IN PLACE, REPLACING THE EXCAVATED MATERIAL, & TAMPING TO SECURE
THE MAT END IN THE KEY.
7. STAPLE/STAKE MAT IN A STAGGERED PATTERN ON 4' (MAX.) CENTERS THROUGHOUT & 2' (MAX.) CENTERS
ALONG SEAMS, JOINTS & ROLL ENDS.
8. ESTABLISH & MAINTAIN VEGETATION SO THAT REQUIREMENTS FOR ADEQUATE VEGETATIVE ESTABLISHMENT ARE
CONTINUOUSLY MET IN ACCORDANCE WITH SECTION B-4 VEGETATIVE STABILIZATION.
