11) dedicated asphalt and concrete batch plants; <br />RESPONSE: Not applicable. There will be no dedicated asphalt and concrete batch plant <br />associated with the planned exploration work. <br />12) non - industrial waste sources such as worker trash and portable toilets; and, <br />RESPONSE: See response to (9) above. <br />13) other areas or procedures where potential spills can occur. <br />RESPONSE: If spills, unforeseen by this SWMP, occur at the project site as a result of RGS <br />activities, RGS will take the necessary steps and procedures to clean up the spills and remove <br />spilled material from the site. Refer to final SPCC plan. <br />c) Best Management Practices (BMPs) for Storm water Pollution Prevention — The SWMP shall <br />identify and describe appropriate BMPs, including, but not limited to, those requiring by <br />paragraphs 1 through 8 below, that will be implemented at the facility to reduce the potential <br />of the sources identified in Part 1.C.3.b to contribute pollutants to storm water discharges. The <br />SWMP shall clearly describe the installation and implementation specifications for each BMP <br />identified in the SWMP to ensure proper implementation, operation and maintenance of the <br />BMP. <br />1) Structural Practices for Erosion and Sediment Control. The SWMP shall clearly describe <br />and locate all structural practices implemented at the site to minimize erosion and <br />sediment transport. Practices may include, but are not limited to: straw bales, <br />wattles /sediment control logs, silt fences, earth dikes, drainage swales, sediment traps, <br />subsurface drains, pipe slope drains, inlet protection, outlet protection, gabions, and <br />temporary or permanent sediment basins. <br />RESPONSE: As appropriate, RGS will use all of the above - listed practices, but, principally, RGS <br />plans to use wattles, sediment fences and soil berms. In addition, interim reclamation will be <br />employed on the portal bench and access road out - slopes and on the growth medium stockpiles <br />to control sediment. Refer to Figure 1a, Stormwater BMP's at the Bulldog Project. <br />Refer to draft SPCC plan for procedures to control and contain spills. <br />2) Non - Structural Practices for Erosion and Sediment Control. The SWMP shall clearly <br />describe and locate, as applicable, all non - structural practices implemented at the site to <br />minimize erosion and sediment transport. Description must include interim and <br />permanent stabilization practices, and site- specific scheduling for implementation of the <br />practices. The SWMP should include practices to ensure that existing vegetation is <br />preserved where possible. Non - structural practices may include, but are not limited to: <br />temporary vegetation, permanent vegetation, mulching, geotextiles, sod stabilization, <br />slope roughening, vegetative buffer strips, protection of trees, and preservation of mature <br />vegetation. <br />RESPONSE: RGS will minimize the area of disturbance for roads and facilities while still <br />providing for worker and equipment safety. Concurrent reclamation will be employed throughout <br />the life of the project when areas are available for reclamation. <br />112 East 12` Street P.O.
