The Office of Management and Enterprise Services (OMES), Central Purchasing Division, is seeking responses on behalf of Department of Environmental Quality from potential Suppliers to provide a contract for services to implement a Municipal Solid Waste Characterization Study of the state’s locally generated residential, industrial/commercial/institutional and construction and demolition waste that is disposed of at MSW landfills in Oklahoma. Eighty-eight material types, aggregated into nine categories, “will be analyzed for the study. We are attempting to establish percent mean composition estimates by weight and by volume where possible, with associated 90% confidence intervals for each material, that are as accurate as possible. This means we seek a statistically valid 90% confidence level that the weight percent of each material in the Oklahomagenerated waste stream or sub-stream is between the high and low estimates calculated from the data acquired in this study, with as narrow a range between high and low estimates as possible. A Contract resulting from this Solicitation may be designated for use as a Statewide Contract.
