Effective stormwater management at temporary batch plants requires implementation of multiple control measures. Photo courtesy of California Stormwater BMP Handbook. Descrip tion Temporary batch plant management includes implementing multiple control measures such as perimeter controls, concrete washout area, stabilized construction access, good housekeeping, and other practices designed to reduce polluted runoff from the batch plant area. Ap prop ria te Uses Implement this control measure at temporary batch plants and identify the location of the batch plant in the SWMP. Additional permitting may be required for the operation of batch plants depending on their duration and location. Design and Installation The following lists temporary management strategies to mitigate runoff from batch plant operations: When stockpiling materials, follow the Stockpile Management Control Measure. Locate batch plants away from storm drains and natural surface waters. A perimeter control should be installed around the temporary batch plant. Install run-on controls where feasible. A designated concrete washout should be located within the perimeter of the site following the procedures in the Concrete Washout Area Control Measure. Follow the Good Housekeeping Control Measure, including proper spill containment measures, materials storage, and waste storage practices. A stabilized construction entrance or vehicle tracking control pad should be installed at the plant entrance, in accordance with the Vehicle Tracking Control Measure. Maintenance and Removal Inspect the batch plant for proper functioning of the control measures, with attention to material and waste storage areas, integrity of perimeter control measures, and an effective stabilized construction entrance.

Description Manage runoff from paving and grinding operations to reduce pollutants entering storm drainage systems and natural drainageways. Appropriate Uses Use runoff management practices during all paving and grinding operations such as surfacing, resurfacing, and saw cutting. Design and Installation There are a variety of management strategies that can be used to manage runoff from paving and grinding operations: Establish inlet protection for all inlets that could potentially receive runoff. Schedule paving operations when dry weather is forecasted. Keep spill kits onsite for equipment spills and keep drip pans onsite for stored equipment. Install perimeter controls when asphalt material is used on embankments or shoulders near waterways, drainages, or inlets. Do not wash any paved surface into receiving storm drain inlets or natural drainageways. Instead, loose material should be swept or vacuumed following paving and grinding operations. Store materials away from drainages or waterways. Recycle asphalt and pavement material when feasible. Material that cannot be recycled must be disposed of in accordance with applicable regulations. See Control Measure Fact Sheets for Inlet Protection, Silt Fence and other perimeter controls selected for use during paving and grinding operations. Maintenance and Removal Perform maintenance and removal of inlet protection and perimeter controls in accordance with their respective fact sheets. Promptly respond to spills in accordance with the spill prevention and control plan.
