THESE AREASARE PLANNED FOR TEMPORARY SEEDING ACCORDING TO THE SEEDING TABLEPROVIDED ON THE EROSION CONTROL DETAIL SHEET (G4.3).PERMANENT SURFACE STABILIZATIONALL AREAS ARE PLANNED FOR PERMANENT SURFACE COVER INCLUDING PAVEDAREAS, PAVED WALKS, BUILDING ROOF TOPS, OR VEGETATIVE COVER. WHENSEASONAL VARIATIONS PREVENT THE INSTALLATION OF THESE SURFACE COVERS,THE CONTRACTOR SHALL INSTALL MULCHING OR EROSION CONTROL BLANKET OVERVULNERABLE DISTURBED AREAS.12EROSION AND SEDIMENT CONTROL MEASURES BUILDING LOTSTHERE ARE NOT INDIVIDUAL BUILDING LOTS CREATED AS PART OF THIS PROJECT.13MATERIAL HANDLING AND SPILL PREVENTIONSPILL PREVENTION SHALL BE ACCOMPLISHED BY UTILIZING SPILL GUARDS FOREQUIPMENT FUELING AND SERVICING OPERATIONS. SPILL GUARDS SHALL BE 3'X3'X6"AND SHALL BE CONSTRUCTED OF A MATERIAL RESISTANT TO PETROLEUMPRODUCTS. ON-SITE FUEL STORAGE TANKS SHALL HAVE EMERGENCY STORAGECAPACITY DIRECTLY BELOW THE TANK IN CASE OF RUPTURE. ANY HAZARDOUSMATERIAL SPILLAGE SHALL BE COLLECTED AND/OR CLEANED IMMEDIATELY BY ATRAINED INDIVIDUAL AND DISPOSED OF IN ACCORDANCE WITH ALL FEDERAL, STATEAND LOCAL REGULATIONS.
