Install fiber mat per manufacturer recommendations. <br />2. Lay fiber mat firmly in place to cover both the inlet grate and overflow area, <br />cut to extend 1" minimum to 3" maximum from edge of grate. <br />3. Install pressure disc anchors per manufacturer at recommended anchor <br />locations and use zip ties to fasten to grate. <br />MAINTENANCE <br />1. Inspection should occur at least once a week and following each %2" or more rain event. <br />2. Broom collected material off filter unit surfaces and away from edges. <br />J. Remove sediment and debris collected around filter units and dispose of legally off site. <br />4. Replace filter unit if it becomes too clogged with sediment to perform properly. <br />Sandbags or other 10 mm Earthen <br />appropriate anchoring Polyethylene Berm Lining buried FIBER MAT <br />system to secure lining Lining under berm <br />(Entry Side only) TEMPORARY TRENCH DRAIN PROTECTION <br />Min. 5' <br />SECTION B—B <br />Earthen <br />10 mm Berm oo Min. 3' <br />Polyethylene <br />Lining <br />Ground <br />EARTHEN BERM SECTION <br />Sandbags or other appropriate <br />anchoring system to secure lining <br />Lining to extend <br />over straw bales <br />Straw Bale (or alternative Straw bales <br />acceptable materials for o �� entrenched <br />- L_ I <br />structural containment) 4 inches into <br />ground <br />Compacted Soil <br />SECTION C—C <br />INSTALLATON <br />1. Either excavate the pit or install the containment system. For prefabricated containers, locate, and install according to the manufacturer's recommendations. <br />2. Prepare a base free of rocks and other debris that may cause tears/punctures in the polyethylene lining. <br />3. Install the polyethylene lining. For excavated systems, extend lining over the entire excavation. For bermed systems, install lining over the pooling area with enough material to extend over the berm <br />or containment system. Secure lining with pins, staples, or other fasteners. <br />4. Place flags, safety fencing, or equivalent for a barrier to construction equipment and other traffic. <br />5. Place a non —collapsing, non —water holding cover over the washout facility prior to a predicted rainfall event to prevent accumulation of water and possible overflow of the system (optional). <br />6. Install signage that identifies concrete washout areas and post signs directing contractors and suppliers to designated locations. <br />7. Where necessary, provide stable ingress and egress or alternative approach pad for concrete washout systems. <br />MAINTENANCE <br />1. Inspect daily and after each storm event — Inspect the integrity of the overall structure and containment system where applicable. <br />2. Inspect the system for leaks, spills, and tracking of soil by equipment, and the polyethylene lining for failure, including tears and punctures. <br />3. Once concrete wastes harden, remove and dispose of the material. <br />4. Remove excess concrete when the washout system reaches 50 percent of the design capacity. Discontinue use until appropriate measures can be initiated to clean the structure. <br />5. Upon removal of the solids, inspect the structure. Repair as needed or construct a new system. <br />6. Dispose of all the concrete in a legal manner. Reuse the material on site, recycle, or haul the material to an approved landfill site. Recycling of material is encouraged. <br />7. Replace the plastic liner after every cleaning. <br />8. Repair or replace system as needed. <br />9. Concrete washout systems are designed to promote evaporation. If liquids do not evaporate and the system is near capacity, vacuum or remove liquids or utilize secondary containment. <br />10. Inspect construction activities on a regular basis to ensure suppliers, contractors, and others are utilizing designated washout areas. If concrete waste is being disposed of improperly, <br />identify violators and take appropriate action. <br />11. When the concrete washout system is no longer required, it shall be closed. <br />12. Backfill, grade and stabilize all holes, depressions and other land disturbances associated with the system. <br />CONCRETE WASHOUT STRUCTURE <br />(Not To Scale) <br />END \ <br />SECTION <br />Illlliil 111 <br />18" MIN DEPTH <br />PLACED BELOW INVERT <br />SECTION A —A <br />SECTION B—B <br />(Not To Scale) <br />4 <br />1� <br />12" <br />T)Qical Swale <br />—NOT TO SCALE— <br />BASIN/POND <br />B TTOM <br />12"_.F( <br />12' <br />GEOTEXTILE III <br />NON —WOVEN FABRIC <br />FI LE <br />..JVEN <br />FABRIC <br />i <br />OUTLET PROTECTION <br />(Not To Scale) <br />1.
