REGULAR MOWING MAY BE NEEDED TO REDUCE COMPETITION FROM WEEDS.

WHEN THE FILTERING CAPACITY OF THE FILTER DIMINISHES SUBSTANTIALLY

(E.G., WHEN WATER PONDS ON THE SURFACE OF THE FILTER BED FOR MORE

THAN 48 HOURS), THE TOP FEW INCHES OF DISCOLORED MATERIAL SHALL BE

REMOVED AND SHALL BE REPLACED WITH FRESH MATERIAL. THE REMOVED

SEDIMENTS SHOULD BE DISPOSED IN AN ACCEPTABLE MANNER (E.G., LANDFILL).

SILT/SEDIMENT SHOULD BE REMOVED FROM THE FILTER BED WHEN THE

ACCUMULATION EXCEEDS ONE INCH.
