DRY SEASON REQUIREMENTS(MAY-SEPT.)

1. WIND EROSION BMPs (DUST CONTROL) SHALL BE IMPLEMENTED.2. SEDIMENT CONTROL BMPs SHALL BE INSTALLED AND MAINTAINED AT ALL OPERATIONAL STORM DRAIN INLETS.3. BMPs TO CONTROL OFF-SITE SEDIMENT TRACKING SHALL BE IMPLEMENTED AND MAINTAINED.4. APPROPRIATE WASTE MANAGEMENT AND MATERIALS POLLUTION CONTROL BMPs SHALL BE IMPLEMENTED TO

PREVENT THE CONTAMINATION OF STORM WATER BY WASTES AND CONSTRUCTION MATERIALS.5. APPROPRIATE NON-STORM WATER BMPs SHALL BE IMPLEMENTED TO PREVENT THE CONTAMINATION OF

STORM WATER FROM CONSTRUCTION ACTIVITIES.6. THERE SHALL BE A "WEATHER TRIGGERED" ACTION PLAN AND THE ABILITY TO DEPLOY STANDBY SEDIMENT

CONTROL BMPs AS NEEDED TO COMPLETELY PROTECT THE EXPOSED PORTION OF THE SITE WITHIN 48 HRS OFA PREDICTED STORM EVENT (A PREDICTED STORM IS DEFINED AS A FORECASTED, 50% CHANCE OF RAIN).

7. SUFFICIENT MATERIALS NEEDED TO INSTALL STANDBY SEDIMENT CONTROL BMPs (AT THE SITE PERIMETER,SITE SLOPES, AND OPERATIONAL INLETS WITHIN THE SITE) NECESSARY TO PREVENT SEDIMENT DISCHARGESFROM EXPOSED PORTIONS OF THE SITE SHALL BE STORED ON SITE. AREAS THAT HAVE ALREADY BEENPROTECTED FROM EROSION USING PHYSICAL STABILIZATION OR ESTABLISHED VEGETATION STABILIZATIONBMPs ARE NOT CONSIDERED TO BE "EXPOSED" FOR PURPOSES OF THIS REQUIREMENT.

8. DEPLOYMENT OF PERMANENT EROSION CONTROL BMPs (PHYSICAL OR VEGETATION) SHOULD COMMENCE ASSOON AS PRACTICAL ON SLOPES THAT ARE COMPLETE FOR ANY PORTION OF THE SITE. STANDBY BMPMATERIALS SHOULD NOT BE RELIED UPON TO PREVENT EROSION OF SLOPES THAT HAVE BEEN COMPLETED.

WET SEASON REQUIREMENTS (OCT.-APRIL)

1. WHERE APPROPRIATE SEDIMENT CONTROL BMPs SHALL BE IMPLEMENTED A THE SITE PERIMETER, AT ALLOPERATIONAL STORM DRAIN INLETS, AND ALL NON-ACTIVE SLOPES, TO PROVIDE SUFFICIENT PROTECTION FORSTORMS LIKELY TO OCCUR DURING THE RAINY SEASON.

2. ADEQUATE PHYSICAL OR VEGETATION EROSION CONTROL BMPs (TEMPORARY OR PERMANENT) SHALL BEINSTALLED AND ESTABLISHED FOR ALL COMPLETED SLOPES PRIOR TO THE START OF THE RAINY SEASON.THESE BMPs MUST BE MAINTAINED THROUGHOUT THE RAINY SEASON. IF A SELECTED BMP FAILS, IT MUST BEREPAIRED AND IMPROVED OR REPLACED WITH AN ACCEPTABLE ALTERNATE AS SOON AS IT IS SAFE TO DO SO.THE FAILURE OF A BMP MAY INDICATE THAT THE BMP, AS INSTALLED, WAS NOT ADEQUATE FOR THECIRCUMSTANCES IN WHICH IT WAS USED. REPAIRS OR REPLACEMENTS MUST RESULT IN A MORE ROBUST BMP,OR ADDITIONAL BMPs SHOULD BE INSTALLED TO PROVIDE ADEQUATE PROTECTION.

3. THE AMOUNT OF EXPOSED SOIL ALLOWED AT ONE TIME SHALL NOT EXCEED THAT WHICH CAN BE ADEQUATELYPROTECTED BY DEPLOYING STANDBY EROSION CONTROL AND SEDIMENT CONTROL BMPs PRIOR TO APREDICTED RAINSTORM.

4. A DISTURBED AREA THAT IS NOT COMPLETED AND IS NOT BEING ACTIVELY GRADED (NON-ACTIVE AREA) SHALLBE FULLY PROTECTED FROM EROSION WITH TEMPORARY OR PERMANENT BMPs (EROSION AND SEDIMENTCONTROL). THE ABILITY TO DEPLOY STANDBY BMP MATERIALS IS NOT SUFFICIENT FOR THESE AREAS. EROSIONAND SEDIMENT CONTROL BMPs MUST ACTUALLY BE DEPLOYED THIS INCLUDES ALL BUILDING PADS,UNFINISHED ROADS, AND SLOPES.

5. SUFFICIENT MATERIALS NEEDED TO INSTALL STANDBY EROSION AND SEDIMENT CONTROL BMPs NECESSARYTO COMPLETELY PROTECT THE EXPOSED PORTION OF THE SITE FROM EROSION AND TO PREVENT SEDIMENTDISCHARGES SHALL BE STORED ON-SITE. AREAS THAT HAVE ALREADY BEEN PROTECTED FROM EROSIONUSING PERMANENT PHYSICAL STABILIZATION OR ESTABLISHED VEGETATION STABILIZATION BMPs ARE NOTCONSIDERED TO BE "EXPOSED" FOR PURPOSES OF THIS REQUIREMENT.
