DISCHARGE FROM THE TEMPORARY POND WILL BE THROUGH A GRAVEL FILER CONE TO THE EXISTING STORM SYSTEM. 3 774E PLANNED CONSTRUCTION ACTIV177ES SHALL BE EVALUATED ON A DAILY BASIS, TAKING INTO CONSIDERATION THE LATEST WEATHER FORECAST. THE WEATHER FORECAST SHALL DICTATE WHETHER LARGE-SCALE EARTH MOVING OPERA7IONS SHALL COMMENCE OR CONTINUE. IF PRECIPITAON OCCURS DU81NC CONSIRUC77ON ACTIVITY, AND IS INTENSE ENOUGH TO GENERATE RUNOFF; ALL EARTH MOVING AC77WTIES SHALL CEASE AND EXPOSED EARTH SHALL BE COERED TO PREVENT EROSION. WHILE PRECIPITATION PERSISTS, THE ONLY CONSTRUCTION AC77WTY THAT SHALL BE ALLOWED ARE THOSE AC77WTIES REQUIRED TO MAINTAIN EXIS77NC EROSION CONTROL MEASURES, INSTALL NEW EROSION CONTROL BMPS AS NECESSARY AND NON-EROSION/SEDIMENT GENERATING AC77W RES 4.
