· SILT FENCES, STRAW WATTLES, AND SEDIMENT TRAPS SHOULD BE INSTALLED AROUND THE PERIMETER OF THE

CONSTRUCTION SITE AND AT SENSITIVE AREAS.

· STABILIZE EXPOSED SOIL AREAS WITH TEMPORARY OR PERMANENT VEGETATION, MULCHING, GEOTEXTILES, OR

EROSION CONTROL BLANKETS.

B. SEDIMENT CONTROL MEASURES:

· USE SEDIMENT BASINS, CHECK DAMS, OR SEDIMENT TRAPS TO CAPTURE RUNOFF AND SETTLE OUT SEDIMENT

BEFORE WATER EXITS THE SITE.

· INSTALL INLET PROTECTION MEASURES ON STORM DRAIN INLETS WITHIN AND ADJACENT TO THE SITE.

C. RUNOFF MANAGEMENT:

· DIVERSION CHANNELS, BERMS, AND OTHER STRUCTURES SHOULD BE CONSTRUCTED TO REDIRECT STORMWATER

AWAY FROM DISTURBED AREAS.

· IMPLEMENT TEMPORARY AND PERMANENT SEEDING, PLANTING, OR SODDING TO REDUCE THE VELOCITY OF

STORMWATER RUNOFF.

D. POLLUTION PREVENTION:

6. COMPLIANCE AND MONITORING

A. INSPECTIONS: THE CONTRACTOR MUST CONDUCT REGULAR SITE INSPECTIONS AT LEAST ONCE EVERY 7 DAYS AND

WITHIN 24 HOURS AFTER A STORM EVENT THAT PRODUCES 0.5 INCHES OR MORE OF RAINFALL. INSPECTIONS MUST FOCUS ON THE EFFECTIVENESS OF THE BMPS AND IDENTIFY ANY DEFICIENCIES OR AREAS WHERE ADDITIONAL

MEASURES ARE NECESSARY.

B. CORRECTIVE ACTIONS: ANY DEFICIENCIES NOTED DURING INSPECTIONS MUST BE ADDRESSED IMMEDIATELY, AND

CORRECTIVE ACTIONS MUST BE DOCUMENTED IN THE SWPPP RECORDS.

C. REPORTING: THE CONTRACTOR SHALL SUBMIT INSPECTION REPORTS, RECORDS OF CORRECTIVE ACTIONS, AND ANY OTHER REQUIRED DOCUMENTATION TO THE ENGINEER FOR REVIEW. NON-COMPLIANCE WITH SWPPP REQUIREMENTS

MAY RESULT IN WORK STOPPAGE AND ENFORCEMENT ACTIONS.

8. FINAL PROJECT DOCUMENTATION - UPON COMPLETION OF THE CONSTRUCTION PROJECT, THE CONTRACTOR SHALL SUBMIT A FINAL REPORT DETAILING THE IMPLEMENTATION AND EFFECTIVENESS OF THE SWPPP, INCLUDING A SUMMARY OF INSPECTIONS, MAINTENANCE ACTIVITIES, AND ANY ISSUES ENCOUNTERED.
