1/21/10 - ADMINISTRATIVE ORDER ON CONSENT ISSUED. AT ALL TIMES RELEVANT TO THIS ACTION, ALDOT OWNED AND/OR OPERATED A CONSTRUCTION SITE KNOWN AS THE BUTTERMILK ROAD PROJECT, A 2.2 MILE PROJECT LOCATED AT COUNTY ROAD 85, NORTH OF COUNTY ROAD 37, TO 0.3 MILES NORTH OF I.59 AT COUNTY ROAD 1481, IN TUSCALOOSA, AL.
ON OCT 15, 2009, EPA IN CONJUNCTION WITH ADEM PERFORMED A COMPLIANCE STORM WATER EVALUATION INSPECTION (CSWEI) AT ALDOT'S DEVELOPMENT. DURING THE CSWEI, EPA INSPECTORS OBSERVED THE FOLLOWING:
A. THE CBMPP WAS NOT CURRENT AND UP TO DATE FOR THE CONDITIONS THAT EXISTED AT THE SITE. THE CBMPPP NEEDED RE-EVALUATION FOR BMPs FOR INLET/OUTLET PROTECTION, A SEDIMENT TRAP AND/OR DIVERSION STRUCTURE AT SEDIMENT BASIN D, CHECK DAMS AT STA #1-2, ADDITIONAL RIP RAP AT THE STORM DRAIN NORTH OF SEDIMENT BASIN B, AND ADDITIONAL SEEDING.
B. BMPs WERE NOT FULLY IMPLEMENTED, MAINTAINED OR EFFECTIVE IN PREVENTING SEDIMENT DISCHARGE AND TO MINIMIZE ADVERSE IMPACTS. THE ROAD CROSSING/STORM PIPE EXTENSION NEAR BRADFORM LANE WAS ALLOWING SEDIMENT LOSS INTO A STORMWATER DITCH CONNECTED TO A STORM WATER SYSTEM WHICH DISCHARGES INTO AN UNNAMED TRIBUTARY AND THEN TO COTTONDALE CREEK.
C. REMEIDATION OF OFF-SITE SEDIMENTATION, AND MEASURES TO PREVENT OR MINIMIZE SEDIMENT DISCHARGE TO THE MAXIMUM EXTENT PRACTICABLE WERE NOT TAKEN. SEDIMENT WAS OBSERVED IN THE UNNAMED TRIBUTARY TO COTTONDALE CREEK BELOW SEDIMENT BASIN D.
ORDER REQUIRES:
