THE IMPLEMENTATION OF THESE ESC PLANS AND THE CONSTRUCTION, MAINTENANCE, REPLACEMENT, AND UPGRADING OF THESE ESC FACILITIES IS THE RESPONSIBILITY OF THE CERTIFIED EROSION SEDIMENT CONTROL LEAD (CESCL) UNTIL ALL CONSTRUCTION IS APPROVED. 2. THE BOUNDARIES OF THE CLEARING LIMITS SHOWN ON THIS PLAN SHALL BE CLEARLY FLAGGED BY SURVEY TAPE OR FENCING, WHERE DETERMINED NECESSARY BY PROJECT ENGINEER, PRIOR TO CONSTRUCTION (2009 SWDM APPENDIX D). DURING THE CONSTRUCTION PERIOD, NO DISTURBANCE BEYOND THE CLEARING LIMITS SHALL BE PERMITTED. THE CLEARING LIMITS SHALL BE MAINTAINED BY THE CERTIFIED EROSION SEDIMENT CONTROL LEAD FOR THE DURATION OF CONSTRUCTION. 3. THE ESC FACILITIES SHOWN ON THIS PLAN MUST BE CONSTRUCTED PRIOR TO OR IN CONJUNCTION WITH ALL CLEARING AND GRADING TO ENSURE THAT THE TRANSPORT OF SEDIMENT TO SURFACE WATERS, DRAINAGE SYSTEMS AND ADJACENT PROPERTIES IS MINIMIZED. 4. THE ESC FACILITIES SHOWN ON THIS PLAN ARE THE MINIMUM REQUIREMENTS FOR ANTICIPATED SITE CONDITIONS. DURING THE CONSTRUCTION PERIOD, THESE ESC FACILITIES SHALL BE UPGRADED AS NEEDED FOR UNEXPECTED STORM EVENTS AND MODIFIED TO ACCOUNT FOR CHANGING SITE CONDITION (e.g. ADDITIONAL COVER MEASURES, ADDITIONAL SUMP PUMPS, RELOCATION OF DITCHES AND SILT FENCES, PERIMETER PROTECTION, ETC.) AS DIRECTED BY THE PROJECT ENGINEER/ECOLOGIST. 5. THE ESC FACILITIES SHALL BE INSPECTED DAILY BY THE CERTIFIED EROSION SEDIMENT CONTROL LEAD AND MAINTAINED TO ENSURE CONTINUED PROPER FUNCTIONING. WRITTEN RECORDS SHALL BE KEPT OF DAILY REVIEWS OF THE ESC FACILITIES. 6. WHERE APPROPRIATE, AREAS OF EXPOSED SOILS, INCLUDING EQUIPMENT ROUTES, THAT WILL NOT BE DISTURBED FOR TWO CONSECUTIVE DAYS DURING THE WET SEASON OR SEVEN DAYS DURING THE DRY SEASON SHALL 1;3E IMMEDIATELY STABILIZED WITH THE APPROVED ESC METHODS (e.g., SEEDING, MULCHING, PLASTIC I COVERING, ETC.) • 7. TEMPORARY PATHS USED FOR EQUIPMENT ACCESS WILL BE RESTORED ONCE CONSTRUCTION IS COMPLETED USING THE APPROPRIATE SEED MIX. ONLY TRACK VEHICLES OR APPROVED EQUIPMENT ARE ALLOWED BEYOND ACCESS, LANDINGS AND STAGING AREAS. 8. ISOLATE MAY CREEK FROM CONSTRUCTION AREA BY USING COFFER DAM, AS DETERMINED FROM SITE CONDITIONS DURING CHANNEL EXCAVATION. INSTALL A CLEAN SUMP UPSTREAM OF COFFER DAM AND PUMP FROM SUMP TO SUITABLE LOCATION AS DETERMINED BY ENGINEER OR BIOLOGIST. 9. PRESERVE EXISTING NATIVE VEGETATION IN CLEARING AREA UNDER DIRECTION OF PROJECT ENGINEER. 10. SOFT, SATURATED, AND NON-BEARING SOILS ARE EXPECTED. THE CONTRACTOR SHALL USE THE APPROPRIATE EQUIPMENT. 11. THE ONLY IN-WATER WORK ALLOWED IS THE WORK REQUIRED TO INSTALL THE STREAM DIVERSION AND DEWATERING SYSTEM. 12. CONSTRUCTION EQUIPMENT SHALL BE OPERATED FROM THE STREAM BANK ONLY. 13. PRESERVE EXISTING NATIVE VEGETATION TO THE MAXIMUM EXTENT POSSIBLE UNDER THE DIRECTION OF THE ENGINEER. 14. PROTECTION OF THE ENVIRONMENT: NO CONSTRUCTION RELATED ACTIVITY SHALL CONTRIBUTE TO THE DEGRADATION OF THE ENVIRONMENT, ALLOW MATERIAL TO ENTER SURFACE OR GROUND WATERS, OR ALLOW PARTICULATE EMISSIONS TO THE ATMOSPHERE, WHICH EXCEED FEDERAL, STATE OR LOCAL STANDARDS.
