Solid Waste
Sunshine Canyon Landfill, Browning Ferris Industries, Sylmar, California
Surface water hydrological and sedimentation study including the installation of two stream gauging stations. Assisted in the preparation of the Solid Waste Assessment Test and performed quarterly monitoring as per the California Code of Regulations (CCR) Title 23, Chapter 15 requirements. This effort was utilized in the successful expansion of the landfill and the reduction of sedimentation releases within the existing facility.
Chestnut Avenue Landfill, Browning Ferris Industries, Selma, California
Technical Management of a compliance audit and a landfill acquisition study including the evaluation and upgrading of the groundwater monitoring well system and vadose zone monitoring system. This class III landfill facility had previously experienced a period of flooding which adversely effected the groundwater quality at the landfill. Extensive investigation and monitoring was necessary to evaluation site conditions. The landfill acquisition study was instrumental in the clients' decision to purchase the landfill. Subsequently, assisted in the preparation of the expansion permit.
Buena Vista Landfill, Buena Vista, California
The County of Santa Cruz owns and operates two landfills, which serve the unincorporated portions of Santa Cruz County. The Ben Lomond Landfill is an inactive landfill upon which final cover has recently been placed. A transfer station currently operates at the Ben Lomond landfill site. The Buena Vista Landfill is an approximately 80-acre active Class III Landfill.
Staff members of EnviroForensics® /Arcient® were instrumental in the completion of a wide range of engineering and hydrogeologic projects. These projects include: site development and operations planning, design and CQA of the Module 3 landfill expansion, perimeter leachate drain design, design and CQA of the Module 1/2 final cover, preliminary design of the soil management area, landfill gas flare system design, topographic mapping, turnkey installation of groundwater monitoring wells and landfill gas probes, and hydrogeologic and groundwater remediation assessments.
A site development and operations plan was prepared for the Buena Vista Landfill. The permitted acreage of this landfill is approximately 80 acres, of which 30 acres have already been filled. The revisions to the site development plan and operations plan were to incorporate Subtitle D requirements, provide for the use of alternative covers, and to accommodate the County’s desire to modify the original sequencing.
Preparation of the revised site development plan require evaluation of the following items: site capacity and site life projection; soils balance; static and seismic stability; settlement; leachate generation; drainage system capacity; and soil erosion analysis. Calculations were performed for each of these items and the results incorporated into the design.
The site development plans were illustrated in development phases with each phase depicting the module boundaries, access roads, stockpile locations, LCRS grading, leachate sump locations, stormwater drainage facilities, and sedimentation pond locations. Representative cross sections and details were also included.
The operations plan addresses material handling activities, ancillary facilities, disposal site controls, site inspection and maintenance, and monitoring and reporting programs. The plan includes existing operational limitations and constraints and also reflects future operations based on the revised site development plans.
Industrial Waste Management
Corn Belt Energy Corporation, Elkhart, Illinois
EnviroForensics® staff assisted Corn Belt Energy Corporation by providing all of the environmental permitting services for a newly planned 90-MW coal-fired Low Em-mision Boiler System Project power plant. The proposed facility is located in Central Illinois. Part of the permitting effort included a New Source Review construction permit.
A permit application was prepared. The permitting authority for the proposed project was the Illinois Environmental Agency. The proposed facility is a demonstration project under the U.S. Department of Energy Clean Coal Program. The permit is a Prevention of Significant Deterioration permit and includes a Best Available Control Technology (BACT) determination for all of the affected pollutants and an ambient air quality impact analysis. The analysis is performed using the industrial source complex (ISC3) dispersion model. Modeling was performed for both steady-state and startup emissions. The results of the modeling were compared to the significant impact level to determine whether emissions will be at an acceptable level.
An air permit for the proposed development was approved. The services provided by engineers of EnviroForensics® were Permit Applications, Air Quality Impact Analyses and Emissions Modeling.
