SB 14 Waste Minimization Plan <br /> DTE Stockton, LLC April 2018 <br /> below the threshold, the ash could then be characterized as non-hazardous. The results of the <br /> sampling effort do allow for the ash to be characterized as non-hazardous waste. The Ash <br /> Management Plan requires that quarterly characterization studies and sampling be conducted to <br /> ensure the thresholds are maintained below the characteristics of a hazardous waste. <br /> 2.9 Schedule and Numerical Goal <br /> As stated above,DTE Stockton generated 23958 tons of hazardous waste in 2017. The facility has <br /> set the numeric goal of reducing this volume by 10% for the year 2018. <br /> The task to achieve this goal requires an aggressive outreach program to identify target markets <br /> that would accept the ash byproduct as a beneficial reuse, and operationally maintaining the <br /> characteristics of the ash below that of hazardous waste. The ash byproduct from producing <br /> electricity would then be changed from a waste to a viable product. <br /> 3.0 HAZARDOUS WASTE MANAGEMENT PERFORMANCE <br /> REPORT <br /> The Hazardous Waste Management Performance Report (Performance Report) documents a <br /> generator's current efforts and effectiveness in managing hazardous waste. The Performance <br /> Report includes discussions of the generator's approaches to managing hazardous waste including <br /> source reduction, on-site and off-site recycling, treatment and disposal. <br /> 3.1 Baseline and Reporting Year <br /> Relevant Plan Dates: <br /> Plan Date: April 2018 <br /> Reporting Year: 2018 <br /> Baseline Year: 2017 <br /> 3.2 Waste Management Approach <br /> The current waste management approach is to identify beneficial reuse options for the byproduct <br /> (e.g., fly ash and bottom ash) from the process of using biomass as fuel to produce electricity. <br /> 3.3 Effect of Waste Management Approach <br /> Preliminary results are favorable, and beneficial reuse options are available. <br /> 3.4 Factors Affecting Major Waste Stream <br /> The primary purpose and responsibility of the DTE Stockton, LLC facility is to use biomass as <br /> fuel to produce electricity. The byproduct of this operation is the generation of ash. As a result, <br /> reducing the material at the source that generates hazardous waste is not technically feasible at this <br /> time. However,the facility has developed an Ash Management Plan to identify options that would <br /> allow for the beneficial reuse of the material, without impacting other environmental <br /> 294354 7 <br />
