urbanized areas are located in the western half of the County along or near the major road corridors such as Interstate 5 and State Highways 22 and 214. The city of Salem, which is incorporated in both Marion and Polk Counties, is the largest city in the County, and serves as the County seat and the capital of the State of Oregon.

Final Draft - CHAPTER 2
2-3 March 2009
The Willamette River Valley is the most diverse agricultural region in Oregon, specializing in crops such as berries, vegetables, hazelnuts, hops, grass seed and nursery products. Marion County is ranked number one in Oregon with respect to agricultural production. Coincident with the growth of agriculture was the development of the food processing industry, which is now one of the largest in the nation. Valley land is also used for grazing and rearing activities to produce livestock and poultry for market.
The economic base of the County includes government, agriculture, food processing, forest products, manufacturing, education and tourism. In 1998 the unemployment rate was 6.3 percent dropping to 5.7 percent in 2005. Table 2-3 provides an economic snapshot of the County.

Salem has a substantial manufacturing sector consisting of food processing and paper goods production. These industries typically are associated with high volumes of food and paper waste by-products.
2.3 Description of the Solid Waste Management
System
The solid waste system in Marion County consists of collection, transfer, waste recovery, recycling, household hazardous waste, composting and disposal facilities and services. Collectively, the facilities and programs in Marion County effectively manage the County’s waste and recyclables. Private sector tonnages not flowing through the County’s facilities are reported to the State either by the generator or the disposal entity. The State computes this private sector tonnage into the County’s overall generation tons and recycling rate. This chapter provides an updated description of the major components of the solid waste management system

in the County. Some of the smaller recycling facilities or specific programs that are currently in place within the County may not be included here but discussed in later chapters. Marion County’s solid waste disposal sites, transfer stations, WTEF and the flow of waste and recovered materials quantities handled in 2006 are shown in Figure 2-1.

2.3.1 Refuse Collection
There are eight private companies that provide collection of municipal solid waste from residences and commercial establishments in Marion County (Table 2-4). Each of these companies is either franchised by the County or by local jurisdictions, under authority granted by ORS 459.125. This same legislation also gives Marion County the authority to:
“Regulate, license, franchise and certify disposal, transfer, and resource recovery sites or facilities; establish and collect license or franchise fees; and otherwise control and regulate the establishment and operation of all public or private disposal, transfer and resource recovery sites or facilities located within the County.”
Final Draft - CHAPTER 2
2-5 March 2009
This authority was granted to enable the County to effectively manage the entire waste stream including that sent to the WTEF.
Franchise agreements grant each company the sole right to collect solid waste and residential curbside recyclables from a specified area, as depicted by Figure 5-1 in Chapter 5. Waste haulers are contractually obligated to provide a regular schedule for collection of garbage in all areas of the County and recyclables in urbanized areas. Service charges by the waste haulers are regulated by cities and by Marion County.

2.3.2 Transfer Stations
There are two transfer stations that operate in Marion County. The Salem/Keizer Recycling and Transfer Station (SKRTS) is located southeast of Salem off Highway 22. The site is owned and operated by Capitol Recycling and Disposal under a contract with the County. In 2000, over 20,000 tons of solid waste were delivered to SKRTS.11 In 2007, the quantity of waste going though the facility jumped to 33,546

tons, an increase of almost 68 percent.12 Solid waste received at SKRTS is
transferred to the WTEF for processing. In addition to the solid waste, recyclables are accepted at SKRTS. Some recyclable materials are transported to the Marion Resource Recovery Facility (MRRF) for sorting and recovery.
Over the years, improvements have been made to SKRTS, allowing for increased area dedicated to receiving source separated recyclable materials. The facility handles many types of recyclable materials brought in by the public in higher quantities such as: lead acid batteries, mixed paper, cardboard, “grey board”, food/beverage container glass, electronics (including: stereos, computers, phones / cell phones, printers, TVs, and microwaves), plastic rigid containers #1-7, and latex paint. In addition, yard debris and wood waste are segregated and transported to a commercial composting facility for recycling. In 2005, a Household Hazardous Waste (HHW) drop-off program was added to the facility as part of a cooperative effort between Marion and Polk Counties.
The County also owns a smaller transfer station located at the North Marion County Disposal Facility (NMCDF) that serves the northern-most portion of the County. The facility is operated by Marion County. NMCDF consists of a series of bays to allow cars and pickup trucks to dump waste that will be transported to the WTEF. The facility includes a drop-off area for source separated recyclable materials. In 2000, the facility received 4,525 tons13 and in 2007 more than doubled that amount, up to
9,467 tons as Table 2-5 and Figure 2-2 show.

2.3.3 Waste-to-Energy Facility (WTEF)
The WTEF began operation in 1986. Covanta Energy, formerly Ogden Martin, operates the facility under a contract with Marion County. The plant is designed to burn approximately 550 tons of municipal solid waste per day or about 185,000 tons per year. The facility converts the energy released during combustion to electricity which is sold to the PGE. The WTEF reduces the total volume of waste by 90 percent. Ash residue is taken to the NMCDF where it is buried in a dedicated lined monofill cell.
In general, there are sufficient quantities of solid waste from Marion County to supply the plant at peak capacity on an annual basis. In the past, during certain times of the year when waste volumes were lower, small amounts of waste were brought in from outside the County. Tonnage originating outside the County and brought to the WTEF has generally increased until 2006 and 2007 when it dropped back below the 2001 amount (See Table 2-6 and Figure 2-3 - WTEF Waste Tonnage).
