Page 1 of 4 Wyoming Dept. of Environmental Quality Wastes Not Acceptable for Disposal in an Unlined C/D (Construction & Demolition) Landfill The City of Douglas Landfill and Transfer Station is an unlined landfill with a permitted C&D cell. All municipal solid waste is shipped to Casper Regional Landfill with the exception of C/D waste, which is allowed to be buried ONLY in the permitted C/D cell. The City of Douglas also operates a recycling center with several recycling and compost dumpsters located around Douglas. For a complete list of recycling/compost dumpster locations, as well as to view an interactive map, go to the Recycling page of our website or use the following link: http://www.cityofdouglas.org/index.aspx?NID=217 Per WYDEQ, SWRR Chapter 1, Section 1(e), the definition of construction/demolition waste is in part: “includes, but is not limited to stone, wood, concrete, asphaltic concrete, cinder blocks, brick, plaster and metal.” Because the definition for C/D waste is non-specific, the following additional information regarding items that may be included in the definition of C/D waste, and of wastes that are, and are not, acceptable in unlined C/D landfills is being provided. Table 1 provides a list of C/D wastes acceptable for disposal in unlined C/D landfills. Table 2 provides a list of C/D wastes unacceptable for disposal in unlined C/D landfills. With respect to certain waste types in Tables 1 and 2, wastes not acceptable for disposal include partially unused containers of materials. For example, empty or dry paint containers may be disposed, containers partially full of liquid paint may not be disposed. Note that the following tables are for illustration purposes only, and they are not intended to be all inclusive. If a [landfill] operator has any questions regarding the acceptability of a particular waste type, please contact Department staff listed at the end of this memorandum. Questions from the public, including commercial haulers, should be directed to the City of Douglas, Public Works Department, [PHONE REDACTED], or the Douglas Landfill scale house, 307- 351-2186. Waste types that may be disposed in an unlined C/D landfill are limited. Rigorous, routine waste screening will be required so that disposal of any prohibited wastes is prevented. Permittees' (e.g. the City of Douglas) failure to strictly comply with waste screening requirements, including failure to refuse prohibited wastes, may result in enforcement action by the Department, including potential revocation of the operating permit as set forth in SWRR Chapter 1, Section 4(b). ---PAGE BREAK--- Page 2 of 4 Table 1.
