1.1. WHEN A STABILIZED CONSTRUGTION ENTRANCE IS NOT PREVENTING SEDIMENT FROM BEING TRACKED ONTO PAVEMENT_ WHi=FC WASHING LS GENERALLY AN EFFECTIVE
EROSION AND SEDIMENT CONTROL METHW ANti BMP WHEN INSTALLED WITH CAREFUL ATTENTION TO TOPOCIRAPHY
2 DESIGN AND WSTALLATION SPEC*XAT10H8
2.1. USE A LOW CLEARANCE TRUCK TO TEST THE WHEEL WASH BEFORE PAVING. ERl-HER A BELLY RUMP OR LOWBOY WILL WORK WELL TO TEST CLEARANCE-
2 MIDPOINT SPRAY NOZZLES ARE ONLY NEEDED IN VERY MUDDY CONDITIONS
Y.3 POLYACRYLAMIDE (PAM) ADDED TO WHEEL. WASHWATER AT A RATE OF D.25-0.5 POUNDS PER 1,004 GALLOPJS OF WATER INCREASES EFFECTIVENESS AND REDUCES
CLEANUP TIME. IF PAM IS ALREADY BEING USED FOR OUST OR EROSION CONTR4XAN❑ IS BEING APPLIED BY A WATER TRUCK_ THE SAME TRUCK MAY BE USED TO
CHANGE THE WASHWATER.
3. MJIIIFTQ"NCE STANDARD$
31 THE WHEEL WASH SHOULD START OUT EACH DAY VOTH CLEAN, FRESH WATER
3.2. THE WASHWATER SHOULD BE CHANGED A MINIMUM OF ONCE PER DAY. ON LARGE EARTHWORK JO&4 WHERE MORE THM110 TO 20 TRUCKS PER HOUR ARE EXPECTED,
THE WASHWATER WILL NEED TO BE CHANGED MORE OFTEN.
3.3. WHEEL WASH! OR TIRE BATH WASHWATER SHALL BE DISCHARGED TO A SEPARATE ONSITE TREATMENT SYSTEM, SUCH AS A CLOSED -LOOP RECIRCULATION SYSTEM OR
