STORM WATER POLLUTION PREVENTION PLAN <br />WITH THE EXCEPTION OF PROPERLY DESILTED WATER FROM SITE DEWATERING, THE <br />CONTRACTOR SHALL NOT DISCHARGE ANY MATERIALS AND/OR LIQUIDS TO THE STORM <br />DRAINAGE SYSTEM. ACTIVITIES OF PARTICULAR CONCERN ARE: <br />A. CONTRACTOR SHALL DESIGNATE A CONCRETE TRUCK CLEAN-OUT AREA COUNTY <br />INSPECTOR APPROVED BEST MANAGEMENT PRACTICES SHALL AT ALL TIMES BE FULLY <br />IMPLEMENTED AT AND AROUND THE CLEAN-OUT AREA. <br />B. TACK COAT AND PRIME COAT ASPHALTS SHALL BE CAREFULLY SPRAYED AND ANY <br />EXCESS MATERIAL SPILLED SHALL BE CLEANED UP IMMEDIATELY BY PROPER <br />METHODS. <br />C. ALL EQUIPMENT REFUELING IN THE PROJECT AREA SHALL BE CAREFULLY DONE TO <br />AVOID SPILLAGE. ANY SPILLS SHALL BE CONTAINED AND CLEANED UP IMMEDIATELY <br />IN ACCORDANCE WITH STATE AND LOCAL REQUIREMENTS. ALL FUELING VEHICLES <br />SHALL BE EQUIPPED WITH SPILL CLEANUP MATERIALS AND EQUIPMENT. <br />D. CONTRACTOR SHALL CONTROL AND PROPERLY DISPOSE OF ALL UQUIDS DURING <br />SAWCUTTING ACTIVITIES <br />GENERAL: <br />1, A CONSTRUCTION ENTRANCE SHALL BE INSTALLED PRIOR TO COMMENCEMENT OF GRADING. LOCATION OF <br />THE ENTRANCE MAY BE ADJUSTED BY THE CONTRACTOR TO FACILITATE GRADING OPERATIONS. ALL <br />CONSTRUCTION TRAFFIC ENTERING THE CONSTRUCTION SITE MUST CROSS THE CONSTRUCTION ENTRANCE. <br />2. CHANGES TO THIS EROSION AND SEDIMENT CONTROL PLAN TO MEET FIELD CONDITIONS SHALL BE MADE <br />ONLY WITH THE APPROVAL OF, OR AT THE DIRECTION OF THE COUNTY ENGINEER. DURING THE RAINY <br />SEASON, PUBLIC ROADWAY SHALL BE KEPT CLEAR OF EARTH MATERIAL AND DEBRIS. <br />THE SITE SHALL BE MAINTAINED SO THAT A MINIMUM OF SEDIMENT LADEN RUNOFF ENTERS THE STORM <br />DRAINAGE SYSTEM AND PUBLIC ROADWAY. THIS PLAN COVERS ONLY THE FIRST WINTER FOLLOWING <br />GRADING. PLANS SHALL BE RESUBMITTED FOR APPROVAL PRIOR TO SEPTEMBER IST OF EACH <br />SUBSEQUENT YEAR UNTIL THE PROPOSED IMPROVEMENTS ARE COMPLETED. <br />3. CONTROL MEASURES SHALL BE INSPECTED AND REPAIRED AT THE END OF EACH WORKING DAY AND, IN <br />ADDITION, AFTER EACH STORM. <br />INSTALL STRAW ROLL <br />AND AT BACK OF WALK Q <br />INSTALL CONSTRUCTION O <br />ENTRANCE PROTECTION <br />®CONTRACTOR TO STABILIZE THROUGH HYDROSEEDING <br />DISTURBED SOIL PRIOR TO RAINY SEASON <br />INSTALL CONCRETE WASHOUT AREA IN <br />LOCATIONS APPROVED BY A CERTIFIED PROFESSIONAL O <br />IN EROSION & SEDIMENT CONTROL <br />®INSTALL EQUIPMENT REFUEL AND SERVICE AREA IN <br />LOCATIONS APPROVED BY A CERTIFIED PROFESSIONAL <br />IN EROSION & SEDIMENT CONTROL <br />INSTALL GRAVEL BAGS AND FILTER FABRI S Q <br />TO PROTECT ALL INLETS (TYP ALL INLET TOO <br />MR• <br />J <br />J <br />F— <br />EROSION CONTROL NOTES: <br />1.

INLET FILTERS SHALL BE PLACED AROUND ALL DRAIN INLETS WHICH COULD RECEIVE <br />DRAINAGE IN UNPAVED AND PAVED AREAS DURING THE WET SEASON <br />(OCTOBER 1 -APRIL 15). <br />5. STORM DRAIN INLET FILTERS PER ATTACHED DETAIL SHALL BE <br />PLACED ON ALL DRAIN INLETS AFTER COMPLETION OF PAVING AND SHALL <br />REMAIN IN PLACE ON A YEAR ROUND BASIS. FILTERS SHALL BE REMOVED BY <br />THE CONTRACTOR UPON ACCEPTANCE OF SUBDIVISION IMPROVEMENTS. <br />6. STABILIZED CONSTRUCTION SITE ACCESS SHALL BE CONSTRUCTED PER <br />ATTACHED DETAIL WHERE CONSTRUCTION TRAFFIC ENTERS OR LEAVES <br />PAVED AREAS. THE STABILIZED ACCESS SHALL REMAIN IN PLACE ON A YEAR <br />ROUND BASIS UNTIL COMPLETION OF CONSTRUCTION. <br />7. SENSITIVE AREAS AND AREAS UNDISTURBED BY GRADING SWILL BE PROTECTED <br />BY FILTER ROLL BARRIER AS SHOWN ON THE ROUGH GRADING PLAN AND <br />CONSTRUCTED PER ATTACHED DETAILS.
