Item-by-item guidance Chapter <br /> 12. Contamination/Hazardous Materials /Wastes <br /> This item is divided into four sections: existing contamination, solid waste,hazardous materials,and hazardous <br /> wastes. Some of the project features described under this item may relate to items discussed in Items 10.a <br /> Geology, 10.b. Soils and Topography, and l l.a.ii. Groundwater. <br /> a. Pre-project site conditions <br /> Include information from the MPCA"What's in My Neighborhood?"database. Include the result of a Phase I <br /> or Phase II Environmental Assessment,if one has been conducted. <br /> Additional Resources: <br /> • The MPCA mapping tool"What's in My Neighborhood?"is located at the web page: <br /> hllp://www.pca.state.mn.us/udg 680 <br /> • The MPCA cleanup programs web page is located here: htip://www.pca.state.mn.us/ud.7 <br /> b. Project Related Generation/Storage of Solid Waste <br /> All types of solid wastes generated by the project that are not considered wastewaters,air emissions,or <br /> hazardous wastes should be identified within this section. This includes all forms of"solid wastes," any <br /> sludges, any ashes from combustion,demolition wastes,construction wastes and asbestos.Estimates of the <br /> composition and quantities should be provided.For common types of wastes of fairly uniform composition, <br /> such as municipal solid waste,the composition need not be identified other than by the type of waste. <br /> The method and location of disposal of all the solid wastes listed should be provided.This should include <br /> information demonstrating that the proposed method and location is environmentally acceptable. If special <br /> precautions will be taken to prevent problems,these should be described. <br /> Discuss source separation,recycling,waste minimization and reduction assessment plans as appropriate. <br /> c. Project Related Use/Storage of Hazardous Materials <br /> List any chemicals or other substances that will be on the site for any purpose. The level of detail provided <br /> should be commensurate with the likelihood that the materials could enter the groundwater or surface water. <br /> Describe the risk associated with the materials and the quantities present or used. <br /> The anticipated contents of all tanks should be specified. It may be useful to show the location of tanks on a <br /> site map or plan. If special precautions will be taken to prevent leaks or other problems,these should be <br /> indicated,including emergency response containment plans. <br /> d. Project Related Generation/Storage of Hazardous Wastes <br /> If hazardous wastes will be generated by the proposed project,include a chemical analysis of the waste <br /> along with how it was determined. Estimates of the composition and quantities should be given. <br /> The method and location of storage and disposal of all the wastes should be provided.This should include <br /> information demonstrating that the proposed method and location is environmentally acceptable. If special <br /> precautions will be taken to prevent problems,these should be described. <br /> Discuss source separation,recycling,hazardous waste minimization and reduction assessment plans as <br /> appropriate. <br /> Environmental Quality Board EAW Guidelines—October 2013 31 <br />
