§ DE~/ELOPMENT~ND EVALUATION OFALTERNATh~ES TABLE 6.5.4-4 Biocycle Farm Alternative 2 Capacrb/(dry tons) MWMC Facilities Plan, Eugene-Springfield Liquid Biosolids on Dewatered Biosolids Non-Buffer Areas on Buffer Areas Year (425 Acres) (132 Acres) 1total 2015 2165 824 2989 2020 2561 905 3466 2025 2451 824 3275 As seer, in Table 6.5.4-4, Alternative 2 provides an average of 17 percent more capacity than Alternative 1. Similar to Alternat4ve 1, the majority of the costs associated with Alternative 2 have already been absorbed in the purchase of the land, installation of the distribution pipeline, construction of the BF pump station (under construction), and the purchase of four hose reel application systems. However, Alternative 2 contains the future additional cost of installation of a dedicated irrigation pipeline. Table 6.5.4-5 lists the major costs associated with Altemative 2. TABLE 6.5.45 Biocycle Farm Alternative 2 Cost Estimate MWMC Facilities Plan, Eugene-Springfield Capital Cost Expansion Phase Item (2004 $) Phase 2 Site preparation of 130 acres $300,000 Purchase 2 hole reels $110,000 Phase 3 Site preparation of 130 acres $300,000 Purchase 2 hole reels $110,000 TBD Dedicated irrigation pipeline $1,500,000 TOTAL COST $2,320,000 The dedicated irrigation system would consist of irrigation tubes on 20- to 30-foot grids with microsprays on a minimum 20- to 30-foot spacing. The irrigation tubes would be connected to a submain manifolded off of a 14-inch buried pipeline. There are several advantages to building a dedicated irrigation pipeline. The system wotad provide a more efficient irrigation application and increase the biosolids receiving capacity at the site. The pipeline would also reduce the labor requirements associated with current h'rigation methods. Thus, better application, less labor, and less money toward labor associated with moving hose reels would result. MWMC_60_REVll DOC 6~45
