1. CONDITION OF USE
1. 1. WERE CONCENTRATED RUNOFF FROM DISTURBED AREAS TO AND FROM PONDS OR TRAPS,
1.2. TO CONVEY RUNOFF INTERCEPTED FROM UNDISTURBED AREAS AROUND THE SITE TO A NONEROSIVE DISCHARGE POINT.
2. MAINTENANCE STANDARDS
2,1, ANY SEDIMENT DEPOSITION OF MORE THAN 0,5 FEET SHALL BE REMOVED SO THAT THE CHANNEL IS RESTORED TO ITS ORIGINAL
DESIGN CAPACITY.
2.2. THE CHECK DAMS SHALL BE EXAMINED FOR SIGNS OF SCOUFJNG AND EROSION OF THE BED AND BANKS. IF SCOURING AND EROSION
HAS OCCURRED, AFFECTED AREAS SHALL BE PROTECTED BY RIPRAP OR AN EROSION CONTROL BLANKET.
