EXHIBIT B: NEW CHAPTER 927 <br />protect water resources from the impacts of sediment runoff. <br />C. No structural sediment controls (e.g., the installation of silt fence <br />or a sediment settling pond in -stream) shall be used in water <br />resources or wetlands. <br />D. Where stream crossings for roads or utilities are necessary and <br />permitted, the project shall be designed such that the number of <br />stream crossings and the width of the disturbance are minimized. <br />E. Temporary stream crossings shall be constructed if water resources <br />or wetlands will be crossed by construction vehicles during <br />construction. <br />P. Construction of bridges, culverts, or sediment control structures <br />shall not place soil, debris, or other particulate material into or <br />close to the water resources or wetlands in such a manner that it <br />may slough, slip, or erode. <br />G. Concentrated stormwater runoff from BMPs to natural wetlands <br />shall be converted to diffuse flow through the use of level <br />spreaders or other such appropriate measure before the runoff <br />enters the wetlands. The flow should be released such that no <br />erosion occurs downslope. Level spreaders may need to be placed <br />in series to ensure non-erosive velocities. <br />H. Protected areas or critical areas, including wetlands and riparian <br />areas shall be physically marked in the field prior to earth <br />disturbing activities. <br />(9) Modifying controls. If periodic inspections or other information indicates a <br />control has been used inappropriately or incorrectly, the applicant shall replace or <br />modify the control for site conditions. <br />(f) NON -SEDIMENT POLLUTANT CONTROLS: No solid or liquid waste, including <br />building materials, shall be discharged in stormwater runoff. The applicant must <br />implement site best management practices to prevent toxic materials, hazardous <br />materials, or other debris from entering water resources, wetlands or the MS4. These <br />practices shall include but are not limited to the following: <br />A. Waste Materials: A covered dumpster shall be made available for the proper <br />disposal of garbage, plaster, drywall, grout, gypsum, and other waste <br />materials. <br />B. Concrete Truck Wash Out: The washing of concrete material into a street, <br />catch basin, other public facility, natural resource or water of the state is <br />prohibited. A designated area for concrete washout shall be made available. <br />
