9/15/11 - ADMINISTRATIVE ORDER ISSUED.
ON MARCH 29, 2011, EPA AND SCDHEC PERFORMED A COMPLIANCE STORMWATER EVALUATION INSPECTION (CSWEI) AT THE DEVELOPMENT TO EVALUATE THE TREATMENT AND DISPOSAL OF STORMWATER.
DURING THE CSWEI, THE FOLLOWING WAS OBSERVED:
A. SEDIMENT WAS OBSERVED WITHIN WATERS OF THE U.S. AT OUTFALL DITCHES #5 AND #9. BMPs WERE NOT SELECTED, INSTALLED AND MAINTAINED TO PREVENT SEDIMENT-LADEN STORMWATER FROM DISCHARGING OFFSITE, ALLOWING SEDIMENT TO ACCUMULATE IN THE WATERBODIES. PARTS 3.13.E AND 4.4 OF THE PERMIT REQUIRE BMPs BE SELECTED, IMPLEMENTED AND MAINTAINED TO ACHIEVE MAXIMUM POLLUTANT REMOVAL. ACCUMULATED SEDIMENT WAS ALSO NOT REMOVED AS REQUIRED BY PART 3.13.B OF THE PERMIT.
THE SITE DEVIATED FROM THE APPROVED SWPPP BY NOT INSTALLING ALL PERMITTED BMPs INCLUDING SEDIMENT TRAPS AND CHECK DAMS NEAR THE ROAD CROSSINGS. THE SWPPP AND MAP WERE NOT UPDATED TO SHOW WHICH BMPs WERE NOT INSTALLED AS REQUIRED BY THE PERMIT.
BMPs, SUCH AS CHECK DAMS, TO PROTECT OUTFALL CHANNELS FROM EROSIVE FLOW WERE NOT INSTALLED AS REQUIRED BY THE PERMIT.
PORTIONS OF THE DEVELOPMENT WHERE CONSTRUCTION ACTIVITIES HAD TEMPORARILY OR PERMANENTLY CEASED WERE NOT STABILIZED WITHIN 14 DAYS.
BMPs, INCLUDING SILT FENCING, THROUGHOUT THE DEVELOPMENT WERE NOT PROPERLY INSTALLED AND MAINTAINED AS REQUIRED. FOR EXAMPLE, SEDIMENT WAS NOT REMOVED AS IT ACCUMULATED ALONG SILT FENCING AND RILLS ALONG SLOPES WERE NOT REPAIRED.
INSPECTION REPORTS REVIEWED DURING CSWE
