MWMC FACILITIES PLAN Biocycle Farm Alternative Recommendation The BF is a valuable asset to MWMC's biosolids application program: As shown above, modifications could be made to the BF to provide even greater biosolids receiving capacity. As shown in section 6.5.3, however, the BF as a non-irrigated land application site provides enough capacity to reduce and maintain solids inventory in the FSLs throughout the design period. Similarly, the reduction in labor costs associated with Alternative 2 do not appear to outweigh the increased cost in installing a dedicated irrigation system. Consequently, it is recommended that Alternative 1 be carried forward. 6.5.5 Seasonal Industrial Waste Facility Alternatives The SIWF is a 290-acre site with 190 acres of irrigated cropland and 25 acres of non-irrigated cropland. The total farmable area is approximately 215 acres. The site is located approximately 1 mile from the BMF and 5 miles north of Eugene. It is currently developed with three 60-acre circles and one 16-acre circle of grass. The irrigation system consists of 1996 Pierce center pivots. A 14-acre, 57-MG storage lagoon is also located at the SIWF site. The lagoon no longer receives influent cannery waste but still contains residual waste from prior years influent. Potential future uses for the lagoon include effluent equalization/storage, BFP filtrate storage, and FSL supernatant equalization/storage/treatment. The SIWF was built in 1983 to avoid introducing high-strength organic waste loads into the WPCF on a seasonal basis. Since the purchase of the land by Eugene-Springfield, the SIWF has not been used for any land application or liquid storage of non-cannery wastewaters, as the site has been dedicated solely to irrigation of cannery wastewater. The land has been leased to a farmer and forage producer to ensure that the site is continuously fanned using sound farm management practices. The land is leased for $6,450 per year. Alternatives for future use of the S1WF have been evaluated. These alternatives include: · Alternative 1 - Continue to lease the SIWF and not develop the site further (No Action) · Alternative 2 - Sell the land · Alternative 3 - Convert the 14-acre lagoon at the SIWF into a fifth FSL · Alternative 4 - Land-apply effluent and biosolids at the SIWF without upgrading the lagoon (assumes that no upgrade of the lagoon will be required) Alternative 1 - No Action, Continue to Lease the SIWF Alternative 1 consists of not developing the SIWF and continuing to lease the land. Advantages and disadvantages of this alternative are listed below. Advantages: · This altemative provides a small annual revenue from leasing the land ($6,450) · Maintains ownership of the SIWF for future use Disadvantages: · Not a profitable alternative for MWMC if the existing permitting structure is maintained. The existing cost for a 5-year NPDES permit for the SIWF is $11,500. 6-46 MWMC_6,0_REV11.DOC
