Environmental Compliance Review Report <br /> H.M. Holloway Landfill December 2017 <br /> 1.0 INTRODUCTION AND PURPOSE <br /> 1.1 INTRODUCTION AND PURPOSE <br /> DTE Stockton, LLC (DTE)retained TRC Solutions, Inc. (TRC) to conduct an environmental <br /> compliance evaluation of H.M. Holloway Class III non-hazardous Industrial Waste Landfill <br /> facility(Holloway) located at 14045 Holloway Road, 4.3 miles northwest of the unincorporated <br /> Lost Hills area of western Kern County, California(Appendix A, Figures I and 2). DTE <br /> Stockton intends to transport biomass fly ash, as a dry product, to the Holloway facility to <br /> stabilize biosolid waste authorized to be disposed at the Holloway facility. Fly ash and bottom <br /> ash generated from DTE's Mount Poso Cogeneration Company, LLC (Mt. Poso)may also be <br /> transported to the Holloway facility as a dry product for the same purposes. <br /> DTE's Stockton and Mt. Poso Facilities are biomass conversion facility operating under <br /> California Energy Commission's (CEC) E0232 and E0213 and Energy Information <br /> Administration's (EIA) Plant identification numbers 54238 and 54626 respectively. DTE <br /> Stockton is a 45 megawatts (MW)biomass-fueled electric generation facility located at 2526 <br /> West Washington Street, Stockton, CA. DTE Stockton commenced commercial operation on <br /> February 21, 2014, and was granted Renewables Portfolio Standard Identification(RPS-ID) <br /> number 60964A by the California Energy Commission on March 7, 2014. The generating <br /> facility has also been assigned the Western Renewable Energy Generation Information System <br /> (WREGIS) Generating Unit identification number W3540 as of July 9, 2014. Mt. Poso <br /> Cogeneration is a 44 MW biomass-fueled electric generation facility located at 36157 Famoso <br /> Road, Bakersfield, CA. The Mt. Poso cogeneration plant was completely converted to run 100 <br /> percent biomass fuel instead of coal in 2012. Biomass conversion is the process of generating <br /> energy by converting materials, such as wood waste, to energy. Fly and bottom ash are <br /> generated during the biomass energy conversion process. <br /> The Holloway facility was constructed on a site that was formerly used for surface mining of <br /> gypsum. The approved Landfill project is authorized to receive 2,000 tons per day of waste <br /> materials consisting of dewatered Class A and B biosolids, treated auto shredder waste, <br /> cogeneration ash(fly ash), spent sandblast media, and lime filter cake. The waste is utilized to <br /> backfill four former contiguous mining pit areas described as "pit areas"E, F, G, and Pit F/G <br /> Connection Area. Only Pit G and Pit F/G connection area are authorized for biosolids and fly <br /> ash disposal. <br /> Biomass fly ash originating from the DTE Stockton and Mt. Poso facilities will be transported <br /> as dry product using the appropriate Bill of Lading and Safety Data Sheet to the Holloway <br /> facility where it will be commingled with biosolid wastes as a stabilizing material during <br /> landfilling of the biosolid wastes. According to DTE Stockton, with the exception of pH levels, <br /> the fly ash is characterized as non-hazardous. The pH of the fly ash produced at both facilities <br /> ranges between 11.00 and 12.70 pH units. The fly ash generated from the DTE Stockton and <br /> Mt. Poso facilities and transported to the Holloway facility will be used as a waste stabilizing <br /> material/product for the biosolid wastes is in conformance with requirements outlined in <br /> Hazardous Waste Fee Health and Safety Code, Chapter 6.5 Hazardous Waste Control, Article <br /> 1 <br />
