THE CONTRACTOR SHALL INSTALL FILTER FABRIC OVER ALL DRAINAGE STRUCTURES FOR THE DURATION OF 13. CONSTRUCTION AND UNTIL ACCEPTANCE OF THE PROJECT BY THE OWNER. ALL DRAINAGE STRUCTURES SHALL BE CLEANED OF DEBRIS AS REQUIRED DURING AND AT THE END OF CONSTRUCTION TO PROVIDE POSITIVE DRAINAGE FLOWS. 2. IF DEWATERING IS REQUIRED, THE CONTRACTOR SHALL OBTAIN ANY APPLICABLE REQUIRED PERMITS. THE CONTRACTOR IS TO COORDINATE WITH THE OWNER AND THE ENGINEER PRIOR TO ANY EXCAVATION. 3. STRIP TOPSOIL AND ORGANIC MATTER FROM ALL AREAS OF THE SITE AS REQUIRED. IN SOME CASES TOPSOIL MAY BE STOCKPILED ON SITE FOR PLACEMENT WITHIN LANDSCAPED AREAS BUT ONLY AS DIRECTED BY THE OWNER. 4. FIELD DENSITY TESTS SHALL BE TAKEN AT INTERVALS IN ACCORDANCE WITH THE LOCAL JURISDICTIONAL AGENCY. IN THE EVENT THAT THE CONTRACT DOCUMENTS AND THE JURISDICTIONAL AGENCY REQUIREMENTS ARE NOT IN AGREEMENT, THE MOST STRINGENT SHALL GOVERN. 5. ALL SLOPES AND AREAS DISTURBED BY CONSTRUCTION SHALL BE GRADED AS PER PLANS. THE AREAS SHALL THEN BE SODDED AS SPECIFIED IN THE PLANS, FERTILIZED, AND MAINTAINED UNTIL HARDY GRASS GROWTH IS ESTABLISHED IN ALL AREAS. ANY AREAS DISTURBED FOR ANY REASON PRIOR TO FINAL ACCEPTANCE OF THE JOB SHALL BE CORRECTED BY THE CONTRACTOR AT NO ADDITIONAL COST TO THE OWNER. ALL EARTHEN AREAS WILL BE SODDED AND MULCHED AS SHOWN ON THE PLANS. 6. ALL CUT OR FILL SLOPES SHALL BE 4 (HORIZONTAL): 1 (VERTICAL) OR FLATTER UNLESS OTHERWISE SHOWN. STABILIZATION PRACTICES TEMPORARY STABILIZATION - SOIL STOCK PILES AND DISTURBED PORTIONS OF THE SITE WHERE CONSTRUCTION ACTIVITY TEMPORARILY CEASES FOR AT LEAST 21 DAYS WILL BE STABILIZED WITHIN 7 DAYS FROM THE LAST CONSTRUCTION ACTIVITY IN THAT AREA. THESE AREAS SHALL BE STABILIZED WITH TEMPORARY SEED AND MULCH. THE SURFACE AREAS OF UNPROTECTED ERODIBLE EARTH EXPOSED BY CLEARING AND GRUBBING, EXCAVATION OR FILLING OPERATIONS SHALL BE KEPT TO A MINIMUM AS PRACTICAL. 14. PERMANENT STABILIZATION - ALL DISTURBED PORTIONS OF THE SITE WHERE CONSTRUCTION ACTIVITIES HAVE PERMANENTLY CEASED WILL BE STABILIZED BY SOD IN ACCORDANCE WITH THE LANDSCAPING PLANS AND/OR CONSTRUCTION PLANS. STRUCTURAL PRACTICES 15. STAKED SILT SCREENS - WILL BE INSTALLED ACCORDING TO THE PLANS TO PROTECT OFFSITE AREAS FROM ANY POSSIBLE ADVERSE EFFECTS FROM SEDIMENTS. SEDIMENT WILL BE REMOVED FROM THE UPSTREAM SIDE OF ANY SILT SCREEN ONCE THE ACCUMULATED SEDIMENT REACHES 1 /3 THE HEIGHT OF THE SILT SCREEN. ANY SEDIMENT DEPOSITS OR SOIL DISTURBANCE CREATED DURING THE INSTALLATION AND REMOVAL OF SILT SCREEN SHALL BE DRESSED TO CONFORM TO THE FINISHED GRADE. THE SILT SCREEN SHALL BE INSPECTED ALONG WITH THE REST OF THE PROJECT ONCE EVERY SEVEN DAYS OR WITHIN 24 HOURS OF A RAINFALL EVENT EXCEEDING 0.5". WHERE DEFICIENCIES EXIST, ADDITIONAL SILT FENCES SHALL BE INSTALLED OR REPLACED. ATTACHMENT OF SILT SCREEN TO EXISTING TREES WILL NOT BE PERMITTED UNLESS APPROVED BY THE PROJECT ENGINEER. 7. THE CONTRACTOR SHALL BE RESPONSIBLE FOR THE CONTROL OF DUST AND DIRT RISING AND SCATTERING IN THE AIR DURING CONSTRUCTION AND SHALL PROVIDE WATER SPRINKLING OR OTHER SUITABLE METHODS OF CONTROL. THE CONTRACTOR SHALL COMPLY WITH ALL GOVERNING REGULATIONS PERTAINING TO ENVIRONMENTAL PROTECTION. 16. 8. THE CONTRACTOR SHALL TAKE ALL REQUIRED MEASURES TO CONTROL TURBIDITY, INCLUDING BUT NOT LIMITED TO THE INSTALLATION OF TURBIDITY BARRIERS AT ALL LOCATIONS WHERE THE POSSIBILITY OF TRANSFERRING SUSPENDED SOLIDS INTO THE RECEMNG WATER BODY EXISTS DUE TO THE PROPOSED WORK. TURBIDITY BARRIERS MUST BE MAINTAINED IN EFFECTIVE CONDITION AT ALL LOCATIONS UNTIL CONSTRUCTION IS COMPLETED AND DISTURBED SOIL AREAS ARE STABILIZED. THEREAFTER, THE CONTRACTOR MUST REMOVE THE BARRIERS. AT NO TIME SHALL THERE BE ANY OFF -SITE DISCHARGE WHICH VIOLATES STATE WATER QUALITY STANDARDS. EROSION AND SEDIMENT TRANSPORT PREVENTION 9. THE WORK SPECIFIED IN THIS SECTION CONSISTS OF MEASURES REQUIRED TO CONTROL EROSION AND TRANSPORT OF SEDIMENTS WITHIN AND FROM THE PROJECT AREA, SO AS TO PREVENT THE DEGRADATION OF RECEIVING WATERS, DETRIMENTAL EFFECTS ON PUBLIC OR PRIVATE PROPERTY ADJACENT TO THE PROJECT AND DAMAGE WITHIN THE PROJECT AREA. THESE MEASURES WILL INCLUDE THE CONSTRUCTION AND MAINTENANCE OF TEMPORARY AND PERMANENT EROSION CONTROLS. 10. CONSTRUCTION OPERATIONS SHALL BE RESTRICTED TO THOSE AREAS WHERE IT IS NECESSARY TO PERFORM FILLING OR EXCAVATION TO ACCOMPLISH THE WORK SHOWN ON THE DRAWINGS AND TO THOSE AREAS WHICH MUST BE ENTERED TO CONSTRUCT TEMPORARY OR PERMANENT STRUCTURES. AS SOON AS THE CONDITIONS WILL PERMIT, RIVERS, STREAMS, IMPOUNDMENT, STORMWATER STORAGE AND CONVEYANCE SYSTEMS AND ANY ONSITE RECEMNG WATER BODIES SHALL BE PROMPTLY CLEARED OF ALL OBSTRUCTIONS PLACED THEREIN OR CAUSED BY CONSTRUCTION OPERATIONS. RUNOFF FROM UNSTABIUZED AREAS SHALL BE DIRECTED TO AND TREATED THROUGH SILT FENCES BEFORE DISCHARGING FROM THE PROJECT AREA. EROSION PRACTICES 11. PERMANENT EROSION CONTROL FEATURES SHALL BE INCORPORATED INTO THE PROJECT AT THE EARLIEST PRACTICAL TIME. TEMPORARY CONTROL FEATURES WILL BE USED TO CORRECT CONDITIONS THAT DEVELOP DURING CONSTRUCTION WHICH WERE NOT FORESEEN AT THE TIME OF DESIGN TO CONTROL EROSION PRIOR TO THE TIME IT IS PRACTICAL TO CONSTRUCT PERMANENT CONTROL FEATURES. 12. TEMPORARY EROSION CONTROL MAY BE USED IN CONTROLLING EROSION IN AREAS WHERE CONDITIONS NOT UNDER THE CONTROL OF THE CONTRACTOR, PRECLUDE COMPLETION OF A SECTION OF A PROJECT IN A CONTINUOUS MANNER, AND FOR CONTROLLING EROSION IN AREAS WHERE CONSTRUCTION OPERATIONS MUST BE PERFORMED SUBSEQUENTLY THAT WILL CAUSE DAMAGE TO PERMANENT EROSION CONTROL FEATURES. TEMPORARY EROSION AND WATER POLLUTION CONTROL FEATURES SHALL CONSIST OF, BUT NOT BE LIMITED TO, GRASS, TEMPORARY MULCHING, SANDBAGGING, SEDIMENT BASINS, SEDIMENT CHECKS/EARTH DITCH CHECKS, BERMS, FLOATING TURBIDITY BARRIERS AND SILT FENCE.

SANITARY WASTE - ALL SANITARY WASTE WILL BE COLLECTED FROM THE PORTABLE UNITS IN A TIMELY MANNER MEETING ALL LOCAL AND STATE REGULATIONS. OFFSITE VEHICLE TRACKING 19. MONITORING OF OFFSITE TRACKING OF SEDIMENTS AT THE ENTRANCES IS ESSENTIAL WHERE SILT FENCE WILL NOT BE PLACED TO ENABLE ACCESS TO THE SITE. IF IT APPEARS THAT SIGNIFICANT AMOUNTS OF SEDIMENT ARE BEING TRACKED OFF THE SITE, GRAVEL ENTRANCES OR OTHER EQUIVALENT MEASURES ARE RECOMMENDED TO HELP DISLODGE THE SOIL, SEDIMENT AND DIRT BEFORE THE VEHICLES LEAVE THE SITE. TIMING OF CONTROL MEASURES 20. AREAS WHERE THE GROUND HAS BEEN DISTURBED AND CONSTRUCTION ACTIVITIES TEMPORARILY WILL CEASE FOR MORE THAN 21 DAYS SHALL BE STABILIZED WITH A TEMPORARY SEED AND MULCH WITHIN 7 DAYS OF THE LAST DISTURBANCE. ONCE CONSTRUCTION ACTIVITY CEASES PERMANENTLY IN AN AREA WHERE THE GROUND HAS BEEN DISTURBED, THAT AREA WILL BE STABILIZED WITH SOD OR OTHER SUITABLE STABILIZATION MATERIALS. AFTER THE SITE IS STABILIZED, ALL EXCESS SEDIMENTS AND DEBRIS WILL BE REMOVED FROM THE PONDS AND STORMWATER CONVEYANCE SYSTEM/STRUCTURES RECEMNG DIRECT RUNOFF FROM THE AREA.
