The following includes, but is not an exhaustive list of examples of temporary pollution control measures that can be used to control erosion and sedimentation:
(A) Structural controls.
(1) Silt fences may be utilized, where necessary, to retain the sediments from disturbed areas within the site and decrease the velocity of sheet flows.
(2) Straw bales may be utilized, where necessary, to retain sediments from disturbed areas within the site and decrease the velocity of sheet flows. Straw bales are particularly useful in paved areas where silt fences cannot be erected.
(3) Stabilized construction entrances shall be designed to reduce the amount of soil tracked off the construction site by vehicles leaving the site. A stabilized construction entrance should be utilized, if necessary, to control tracking. The responsible party shall ensure that vehicles entering and leaving the construction site use the stabilized construction entrance. The owner or operator of a vehicle entering or leaving a construction site may not track soil off the construction site.
(4) Vegetative buffer strips, of appropriate size, should be maintained, where necessary and practical, to aid in reducing the velocity of stormwater and in trapping sediments in the stormwater leaving the site. A vegetative buffer will usually suffice as a structural control until final stabilization is accomplished.
(5) Inlet protection barriers must be installed around all inlets until the area immediately surrounding the inlet is paved or stabilized.
(B) Waste controls. Waste disposal must be accompanied in a manner so that no solid wastes, including building materials, hazardous substances, oil or packaging leave the site, except for disposal at an appropriate, approved solid waste management facility, in conformance with the Texas Solid Waste Disposal Act. To the extent practicable, no solid waste, including personal waste, building materials, hazardous substances or oil may be allowed to enter the city's municipal separate storm sewer system, the city's streets or the navigable waters of the United States. Building materials include, but are not limited to, uncovered stockpiles of soil, sand, dry cement, lumber, bricks, packaging or other products used in construction. The general contractor and/or builder, who are issued the building permit, are responsible for the conduct of all subcontractors with regards to disposal of wastes generated by the construction activities at the site.
(C) Soil stockpiles. Stockpiles must be stabilized or covered at the end of each workday.
(D) Dust control. Reasonable measures shall be taken to control dust, particulate matter and windblown debris.
(E) Hazardous material storage. Chemicals, paints, solvents, fertilizers and other toxic materials must be stored in waterproof containers. Except during applications, the contents must be kept in trucks or in storage facilities. Runoff containing such materials shall be collected, removed from the site and disposed of at an approved solid waste or chemical disposal facility.
(F) Concrete trucks. The responsible party may not allow the owner or operator of a concrete truck to wash out or discharge surplus concrete or drum wash water at a construction site, unless the surplus concrete or drum wash water in concrete trucks is discharged at a facility on the construction site that will retain all concrete wash waters or leachates, including any wash waters or leachates mixed with stormwater. Concrete wash waters and leachates may not be allowed to enter the municipal separate storm sewer system, city streets, the waters of the United States or groundwaters.
(G) General good housekeeping measures. Providing general good housekeeping measures to prevent and contain spills of stucco and paints, solvents, fuels, septic waste, concrete washout, and other hazardous chemicals and pollutants associated with construction, and to ensure proper cleanup and disposal of any such spills in compliance with state, federal and local requirements.
