24 HOURS FOLLOWING A STORM EVENT. SEDIMENT SHALL BE REMOVED TO INSURE THE FACILITIES
WILL FUNCTION PROPERLY. THE FACILITIES SHALL BE SATISFACTORILY MAINTAINED UNTIL
CONSTRUCTION IS COMPLETED AND THE POTENTIAL FOR ON —SITE EROSION HAS PASSED.
8. ALL STORM DRAIN INLETS MADE OPERABLE' DURING CONSTRUCTION SHALL BE PROTECTED SO THAT
STORMWATER RUNOFF SHALL NOT ENTER THE CONVEYANCE SYSTEM WITHOUT FIRST BEING FILTERED
OR OTHERWISE TREATED, TO REMOVE SEDIMENT.
9. FROM APRIL 1 T0' SEPTEMBER 30, NO DISTURBED SOIL SHALL REMAIN UNSTABILIZED FOR MORE THAN SEVEN DAYS.
FROM OCTOBER 1 TO MARCH 31, NO', DISTURBED SOIL SHALL REMAIN UNSTABIGZED FOR MORE THAN TWO DAYS.
