2.2. DO NOT USE CRUSHED CONCRETE, CEMENT, OR CALCIUM CHLORIDE FOR CONSTRUCTION ENTRANCE STABILIZATION BECAUSE THESE PRODUCTS RAISE pH
LEVELS IN STORMWATER AND CONCRETE DISCHARGE TO SURFACE WATERS OF THE STATE IS PROHIBITED.
2.3. HOG FUEL (WOOD BASEO MULCH) MAY BE SUBSTITUTED FOR OR COMBINED WITH QUARRY SPALLS IN AREAS THAT WILL NOT BE USED FOR PERMANENT ROADS.
HOG FUEL IS NOT RECOMMENDED FOR ENTRANCE STABILIZATION IN URBAN AREAS. THE INSPECTOR MAY AT ANY TIME REQUIRE THE LISP OF QUARRY SPALLS
IF THE HOG FUEL i NOT PREVENTING SEDIMENT FROM BEING TRACK ❑ ❑NT❑ PAVEMENT OR IF THE H05 FUEL IS BEING CARRIED ONTO PAVEMENT
2.4. FENCING SHALL BE INSTALLED AS NECESSARY TO RESTRICT TRAFFIC TO THE CONSTRUCTION ENTRANCE.
2.5- WHENEVER POSSIBLE. THE ENTRANCE SHALL BE CONSTRUCTED ON A FIFRM. COMPACTED SUBGRAUE. THIS CAN SUBSTANTIALLY INCREASE THE
EFFECTIVENESS OF THE PAD AND REDUCE THE NEED FOR MAINTENANCE

3.1. QUARRY SPALLS SHALL HE ADDED IF THE PAD 15 NO LONGER IN ACCORDANCE WITH THE SPECIFICATIONS.
3.2. IF THE ENTRANCE IS NOT PREVENTING $EDWENY FROM BEING TRACKED ONTO PAVEMENT, THEN ALTERNATIVE MEASURES TO KEEP THE STREETS FREE OF
SEDIMENT SHALL 13C USED. THIS MAY INCLUDE STREET SWEEPING, AN INCREASE IN THE DIMENSIONS OF THE ENTRANCE. DR THE INSTALLATION OF A WHEEL
WASH IF WASHING LS USED, IT SHALL BE DONE ON AN AREA COVERED WITH CRUSHED ROCK, AND WASH WATER SHALL DRAIN TO A SEDIMENT TRAP OR POND
3.3, ANY SEDIMENT THAT IS TRACKED ONTO PAVEMENT SHALL BE REMOVED IMMEOIAT ELY BY SWEEPING. THE SEDIMENT COLLECTED BY SWEEPING SHALL BE
REMOVED OR STABILIZED ON SITE. THE PAVEMENT SHALL NOT BE CLEANED BY WASHING DDWN THE STREET, EXCEPT WHEN SWEEPING IS rNEF FECTIVE AND
THERE IS A THREAT TO PUBLIC SAFETY. IF IT IS NECESSARY TO WA511 THE STREETS. A SMALL SUMP MUST BE CONSTRUCTED. THE SEDIMENT WOULD THEN BE
WASHED INTO THE SUMP WHERE IT CAN BE CONTROLLED AND DISCHARGED APPROPRIATELY. WASH WATER MUST BE PUMPED BACK ONTO THE SITE AND
