,�, _, REFUSE DERIVED FUEL/RESOURCE RECOVERY In December, 1984, Ramsey and Washingtan Counties entered into an agreement with Northern States Power Company (NSP} for the design, construction, ownership, and operation of a$21 million resource recovery facility for refuse derived fuel (RDF) facility to be located on a seventeen acre industrial site in the Ci�.y of Newport, Washington County, near Highways 61 and Interstate 494. {Exhibit A.) An RDF facility houses equipment which processes raw refuse by first removing recyclable materials and nonburnabl.e items. '°"# Machinery then chops and shreds the remain�ng retuse into a uniform, t�uffy, almost odor-free praduct that will burn in boilers. This particuZar plant is designed to process about two- ,� thirds (1,000 tons per day) of the Counties' municipal waste, producing in the process about 70� tons of refuse deri.ved fuel.. � NSP anticipates that the RDF facility will begin operations in the secand half of 1987. It will. employ fifty people and operate about sixteen hours per day, six days per week. The RDF faci�ity will receive, through designation ordinance, a11 municipal waste �rom Washington/Ramsey Caunty, excepting that which �s removed from the waste stream through community waste reduction and sou�ce separation effarts. ' The RDF facility will receive approximately 250 enclosed packer truck laads each day of operation. Zt is ant,icipated that fifty pezcent of the volume received wil� be deposited between 8:00 a.m. and 10:a0 a.m., and 2:Q0 p.m. and 4:00 p.m. each day. As trucks enter the facility, they will proceed tfl a we�gh-in point. Computers will p�ovide a daily recard of al.l events and transac-- tions. After weights are recorded, the vehicles wi11 proceed to an l enclosed "ta.pping floor" where the trash wi1.l be un�oaded. The tloor is designed to accommodate seven�.y vehicles per hour. To ensure that no unacceptable wastes (Table A) or non-pzocessable � wastes {Table B) are accepted, two inspections of the refuse will occur. This will also minimize potential machinery damage, explosion, and/or fire accurrences. The initial inspection will � oecur as the f loor loader spreads the refuse on �he tipping floor. Unacceptable items, such as propane tanks and gasoline cans, wili be removed. A second inspection/removal will occur � as material enters the process line. g�ass which creates boiler damage by melting znto slag will be rerimoved either mechani.cally or manually. Because it will be o� mixed colors, glass will have m�nimal recycling value, and will most likely be landfilled. � � 27 �_.
