impacts would not be implemented. This method ensures that that only those source reduction measures that pass all of the above evaluation factors be deemed feasible for implementation in this SB 14 Plan. 4.3. ACCEPTED MEASURES The following provides a summary discussion for each of the accepted and rejected source reduction alternatives identified in Appendix C,as well as an explanation for its acceptance or rejection within this SB 14 Plan. Source reduction measures that have been investigated or used in the past but are no longer employed are not described here. CWC#S71-BED ASH&FLY ASH Ash is generated from the combustion of woody biomass. #S71-1 Contracts are in place to accept woody biomass based on specifications. Woody biomass selection The quality of the woody biomass has a direct impact to the whether the bed ash and fly ash will be hazardous.DTE Stockton visually screens the woody biomass as well as using a magnetometer to limit the amount of Accepted metal impurities in their fuel. #571-2 DTE Stockton will continue to review the ash management plan.The Ash management plan bed and fly ash are tested quarterly for hazardous waste characteristics. If it is determined to be non-hazardous,the bed and fly ash are sent off as non-hazardous material.Generally,metals and high pH are the main Accepted causes for the ash to be hazardous. #571-3 The production of ash is a direct result of burning woody biomass,so a Change of fuel stock change of fuel would reduce the amount of hazardous waste.However, the facility is not currently configured to use coal or tires for fuel.The Rejected facility also has currently active contracts for receiving regular deliveries of woody biomass. 4.4. MULTIMEDIA EFFECTS SB 14 specifies that implemented source reduction measures cannot merely transfer the waste load from one environmental medium (air,land,or water)to another. The Plan must include an evaluation and,to the extent practicable,a quantification of the effects of the chosen alternative on all three environmental media. Based on best information available at this time,the selected source reduction alternatives identified above do not shift or transfer waste load to other environmental media. 4.5. IMPLEMENTATION SCHEDULE AND GOALS Tables 3 in Appendix B provides a 4-year implementation schedule for the feasible source reduction measures previously discussed above,including major tasks required to be completed for each major waste stream. The implementation timeline for each feasible measure has been forecasted until the next SB 14 reporting year. Table 4 in Appendix B provides estimated source reduction targets for each of the major waste streams over the next 4 years,and calculates the overall estimated waste reductions on a percentage basis. Note that these source reduction goals are subject to change based upon future monitoring of these source reduction measures. It should be noted that actual waste reduction activity over the next four years may not be reflective of source reduction efforts due to fluctuations in normal business cycles and other circumstances.
