EXHIBIT 5 TECHNICAL SITING CRITERIA'S The second category of criteria to develop includes technical parameters that help define the best potential facility sites. These criteria provide guidance on specific engineering, operation, and transportation conditions that should be considered to ensure that potential sites are feasible from technical, environmental, and economic perspectives. These criteria address the following issues: ¦ Central location to collection routes - To maximize waste collection efficiency, transfer stations should be located centrally to waste collection routes. As a rule of thumb in urban and suburban areas, transfer stations should be no more than 10 miles away from the end of all collection routes. Beyond that distance, collection routes might need to be altered to enable refuse to be collected and deposited at the transfer station within one operating shift. ¦ Access to major transportation routes - The transfer station should have direct and convenient access to truck routes, major arterials, and highways (or rail or barge access, if appropriate). For large metropolitan areas, direct access to rail lines or barges will significantly reduce the number of large transfer trailers leaving the station and traveling area roads. It is preferable to avoid routing traffic through residential areas because traffic generated by transfer stations contributes to congestion; increased risk to pedestrians; increased air emissions, noise, and wear on roads; and might contribute to litter problems. ¦ Site size requirements - The area required for specific transfer stations varies significantly, depending on the volume of waste to be transferred, rates at which waste will be delivered, the functions to be carried out at the site, and the types of customers the facility is intended to serve. Locating a site of sufficient size is critical to operating efficiencies and minimizing impacts on the surrounding community. Engineering input can establish preliminary size criteria based on a conceptual design. ¦ Sufficient space for on-site roadways, queuing, and parking - Transfer stations typically have on-site roadways to move vehicles around various parts of the transfer site. Waste collection trucks can be up to 40 feet long. Transfer trailers that move waste to a disposal facility are typically 50 to 70 feet long. These vehicles need wide roadways with gradual slopes and curves to maneuver, efficiently and safely. Also, the site will need space for parking transfer, vehicles and to allow incoming and outgoing traffic to form lines without backing up onto public roads. ¦ Truck and traffic compatibility - Transfer stations often receive surges of traffic when collection vehicles have finished their routes. Transfer station traffic varies locally but tends to peak twice a day. The first peak is often near the middle of the day or shift, and the second at the end of the day or shift. Therefore, the best sites for transfer stations are located away from areas that have midday traffic peaks and/or school bus and pedestrian traffic. 1 Waste Transfer Station: A Manual for Decision-Making, EPA. `` `?a' OLVER P W 1
