• A material inventory will be maintained for all chemicals used on site. Material <br />Safety Data Sheet (MSDS) will be available for any chemical substance used on <br />site. It is not anticipated that reportable quantities of acids, solvents, paints, <br />chemicals or other liquid materials will be stored or used for the purpose of sand <br />and gravel production. These materials will be stored out of the weather, if at all <br />practicable. Any chemicals or products used on site will be kept in the original <br />labeled containers. Damaged or otherwise illegible labels will be replaced. <br />• In the event of a spill, the principal steps in responding to the spill are: <br />1. Stop the source of the spill or leak. <br />2. Contain the spill or leak. <br />3. If release involves a reportable quantity, report spill to appropriate <br />regulatory authority. <br />4. Clean up the spill or leak. <br />5. Dispose of materials contaminated by the spill, according to <br />manufacturer's instructions and / or according to Federal, State, or local <br />requirements. <br />5.3.5 Dedicated Concrete or Asphalt Batch Plants <br />Future plans call for both a concrete batch plant and an asphalt plant associated with <br />this project. <br />5.3.6 Vehicle Tracking Control <br />Most hauling operations off the gravel roads will be restricted to delivering materials to <br />the processing site and operating mining equipment. Signage will be installed to direct <br />construction traffic onto the vehicle tracking control locations, if installed. If the <br />operation's progress necessitates the installation of a stabilized construction entrance <br />(SCE), new ones will be constructed as needed. <br />Mud and debris tracking from the site onto adjacent dirt and gravel roads then onto any <br />distal paved roads will be cleaned as needed through sweeping and collection methods. <br />Wastes generated from said cleaning will be properly disposed of and neither allowed to <br />enter the storm drainage system nor washed from the roadway. Wastes collected by <br />the mechanical street sweeper will be disposed of properly off site. <br />5.3.7 Waste Management and Disposal, Including Concrete Washout <br />Solid waste, such as general refuse and litter, will be contained in plastic bags or trash <br />containers located in the beds of vehicles or dumpsters and disposed of properly offsite. <br />Concrete placements are anticipated on this property; therefore, concrete washout <br />water from concrete washout activities shall not be allowed to discharge from the site <br />as surface runoff or to surface waters.
