where it is disposed. Further, disposal at sites other than a local site simply shifts the location but does not contribute to waste reduction. Mandatory source - separation of multiple C &D materials is not practiced anywhere in North Carolina. The only places in the country we are aware of now requiring source separation of construction and demolition wastes are Portland Oregon and Passaic New Jersey. Any strategy based on policing of C &D waste to ensure proper separation for recycling or reuse, would require significant enforcement infrastructure. Key Issues: This is the simplest aspect of regulatory measures to implement as we have control over the existing C &D landfill. The Board of Commissioners could enact disposal bans or additional fees for improperly separated loads. Too rigorous a set of enforcement regulations could result in illegal dumping, loss of revenue from materials going to other facilities or numerous conflicts over tolerance levels for "banned" materials. e.g. "How much wood is too much mixed in a load where clean construction wood was "banned ?" Costs: We believe that if bans or differential fees were implemented, we would be obligated to provide alternative management facilities and techniques for the source - separated materials. Those facilities would require staff and capital investments to be effective. C. Processing and Sorting Construction and demolition materials may be source - separated as result of regulation, economic incentives and disincentives, or desire of construction and demolition contractors to conform to environmentally sound practices. Separated materials are typically delivered to a processing site. Even when source - separated, additional handling and processing are required before such materials are marketable. C &D materials may also be mixed together at the work site and delivered to a disposal or recycling facility and disposed or separated there. Typically, it is less expensive and more efficient to processing and recycling operations at a disposal site to eliminate need to further handle and transport residues and unrecyclable loads. 1. Source Separation Under either the source - separated or mixed debris processing scenario, there are expenses associated with sorting and processing materials for markets. It is typically simpler and less expensive to manage source - separated materials than mixed materials received at a recycling site because the sorting costs have been " shifted" upstream to the generator or hauler. 26
