CLEARING LIMITS SHALL BE PERMITTED. THE CLEARING LIMITS
SHALL BE MAINTAINED BY THE APPLICANT/ESC SUPERVISOR FOR
THE DURATION OF CONSTRUCTION.
4. STABILIZED CONSTRUCTION ENTRANCES SHALL BE INSTALLED
AT THE BEGINNING OF CONSTRUCTION AND MAINTAINED FOR
THE DURATION OF THE PROJECT. ADDITIONAL MEASURES, SUCH
AS CONSTRUCTED WHEEL WASH SYSTEMS OR WASH PADS, MAY
BE REQUIRED TO ENSURE THAT ALL PAVED AREAS ARE KEPT
CLEAN AND TRACK OUT TO ROAD RIGHT OF WAY DOES NOT
OCCUR FOR THE DURATION OF THE PROJECT.
5. ALL REQUIRED SEDIMENTATION/EROSION CONTROL FACILITIES
MUST BE CONSTRUCTED AND IN OPERATION PRIOR TO LAND
CLEARING AND/OR CONSTRUCTION TO PREVENT
TRANSPORTATION OF SEDIMENT TO SURFACE WATER, DRAINAGE
SYSTEMS AND ADJACENT PROPERTIES. ALL EROSION AND
SEDIMENT FACILITIES SHALL BE MAINTAINED IN A
SATISFACTORY CONDITION UNTIL SUCH TIME THAT CLEARING

THAT CONTAIN FINE PARTICLES AND HIGH pH, BOTH OF WHICH
CAN VIOLATE WATER QUALITY STANDARDS IN THE RECEIVING
WATER. THIS BMP IS INTENDED TO MINIMIZE AND ELIMINATE
CONCRETE PROCESS WATER AND SLURRY FROM ENTERING WATERS
OF THE STATE.
DESIGN: CONCRETE TRUCK CHUTES, PUMPS AND INTERNALS SHALL BE
WASHED OUT ONLY INTO FORMED AREAS AWAITING INSTALLATION
OF CONCRETE OR ASPHALT. (CONCRETE TRUCK CHUTES, PUMPS,
ETC. SHALL NOT BE WASHED IN SUBGRADE AREAS OF PROPOSED
POROUS ASPHALT/INFILTRATION)
WHEN NO FORMED AREAS ARE AVAILABLE, CONTAIN WASHWATER
AND LEFTOVER PRODUCT IN A LINED CONTAINER. DISPOSE OF
WASHWATER INA MANNER THAT DOES NOT VIOLATE
GROUNDWATER OR SURFACE WATER QUALITY STANDARDS.
UNUSED CONCRETE REMAINING IN THE TRUCK AND PUMP SHALL BE
RETURNED TO THE ORIGINATING BATCH PLANT FOR RECYCLING.
HAND TOOLS SHALL BE WASHED OFF ONLY INTO FORMED AREAS
AWAITING INSTALLATION OF CONCRETE OR ASPHALT.
EQUIPMENT THAT CANNOT BE EASILY MOVED, SUCH AS CONCRETE
PAVERS, SHALL BE WASHED IN AREAS THAT DO NOT DIRECTLY
DRAIN TO A NATURAL OR CONSTRUCTED STORMWATER
CONVEYANCES.
WASHDOWN FROM AREAS SUCH AS CONCRETE AGGREGATE
DRIVEWAYS SHALL NOT DRAIN DIRECTLY TO NATURAL OR
CONSTRUCTED STORMWATER CONVEYANCES.

PURPOSE: SAWCUTTING AND SURFACING OPERATIONS GENERATE SLURRY AND
PROCESS WATER THAT CONTAINS FINE PARTICLES AND HIGH pH
(CONCRETE CUTTING), BOTH OF WHICH CAN VIOLATE WATER QUALITY
STANDARDS IN THE RECEIVING WATER. THIS BMP IS INTENDED TO
MINIMIZE AND ELIMINATE CONCRETE PROCESS WATER AND SLURRY
FROM ENTERING WATERS OF THE STATE.
DESIGN: VACUUM SLURRY AND CUTTINGS DURING CUTTING AND SURFACING
OPERATIONS.
DO NOT LEAVE SLURRY AND CUTTINGS ON PERMANENT CONCRETE OR
ASPHALT PAVEMENT OVERNIGHT.
DO NOT DRAIN SLURRY AND CUTTINGS TO ANY NATURAL OR
CONSTRUCTED DRAINAGE CONVEYANCES.
DISPOSE OF COLLECTED SLURRY AND CUTTINGS IN A MANNER THAT
DOES NOT VIOLATE GROUNDWATER OR SURFACE WATER QUALITY
STANDARDS.
DO NOT DRAIN PROCESS WATER THAT IS GENERATED DURING
HYDRO -DEMOLITION, SURFACE ROUGHENING, OR SIMILAR OPERATIONS
TO ANY NATURAL OR CONSTRUCTED DRAINAGE CONVEYANCE. DISPOSE
OF PROCESS WATER IN A MANNER THAT DOES NOT VIOLATE
GROUNDWATER OR SURFACE WATER QUALITY STANDARDS.
HANDLE AND DISPOSE OF CLEANING WASTE MATERIAL AND
DEMOLITION DEBRIS IN A MANNER THAT DOES NOT CAUSE
CONTAMINATION OF WATER. IF THE AREA IS SWEPT WITH A PICK-UP
SWEEPER, HAUL THE MATERIAL OUT OF THE AREA TO AN APPROPRIATE
