1. Construction Site Practices. In addition to compliance with specific requirements <br />contained in an approved permit, all permittees shall establish and implement construction site ~ ~~ <br />management practices that will prevent toxic materials and other debris from entering the City's <br />storm drainage and waterway systems. The following construction site practices are prohibited and <br />constitute a violation of these rules: <br />1.1 Improper storage of chemicals (pesticides, fertilizers, fuels, paints, thinners); <br />1.2 Improper disposal of construction waste material; garbage; rubbish, and <br />sanitary waste, plaster, dry-wall, grout, gypsum; <br />1.3 Failure to immediately clean up spills of toxic materials; <br />1.4 Washing excess concrete material into a street, catch basin, or other.public <br />facility or a related natural resource; <br />1.5 Leaving stockpiles uncovered; or <br />1.6 Allowing construction vehicles to track or spill soil or debris into or onto a <br />street or public right of way. <br />2. Prevention Measures and Design Standards. The City's Erosion Prevention and <br />Construction Site Management Practices Manual may be utilized to obtain ideas as to how to achieve <br />the outcomes mandated by R-6.645-D.1. These ideas include: <br />2.1 Keep vehicles on gravel or paved surfaces. <br />2.2 Surface stabilization measures (seeding, sodding, mulching, riprap); <br />2.3 Runoff control measures (temporary and permanent diversions, grassed- <br />swales, slope drains, riprap channels); <br />2.4 .Outlet protection measures (energy spreaders/dissipaters); <br />2.5 Inlet protection measures (fabric-sod type protectors); <br />2:6 Sediment trap measures (basins, fences, rock dams); <br />2.7 Stream protection measures (temporary and permanent stream crossings, <br />buffers, vegetated and structural stabilizers); <br />2.8 Construction timing and sequence; <br />2.9 Areas not to be disturbed; and . <br />2.10 Other measures such as: subsurface drains, check dams, dust control, <br />practices and procedures of.operations. <br />The Manual is a guidance documenJ.enly. It is not adopted as part of these rules. It is not necessary <br />to utilize any of the specific concepts contained in the Manual, nor is the use of one or more of those <br />ideas a guarantee that a permit will be issued. Each site and the proposed construction related <br />activities need to be examined to determine what measures are required for that specific site. <br />R-6.645-H Enforcement. <br />Proposed Erosion Prevention Administrative Rule R-6.645 - 14 12/4196 <br />
