PVNavigator, LLC has received conditional approvals from New Jersey’s Board of Public Utilities (NJBPU) to design, build and operate a 3.9MW (DC) racked PV solar power installation at the Owens Corning’s closed Somerdale Landfill (300 Somerdale Road, Gloucester, NJ 08083) in Camden County. The Board’s actions, together with an earlier NJ Department of Environmental Protections (NJDEP) approval of a landfill closure and PV solar, post closure use permit, paves the way for PVN to start design activities on the project.
The work was funded by the California Energy Commission. The final report evaluated the performance of a solar racking system at the closed Operating Industries Incorporated (OII) Landfill in Monterrey Park, California a suburb in Los Angeles County located 15 miles southeast from Downtown. The system was placed at the landfill for over a year to assess its power performance and to assess its effect on the stability on the landfill cover. Geotechnical data collected during the project demonstrated that the solar racking system did not adversely affect the integrity of the landfill cover. The vegetation growth under the solar racking system was only slightly affected. No cap penetration was caused by the footings of the solar racking system. The results from this study indicated that a solar racking system on a closed large landfill is a feasible renewable alternative.
Project Navigator, Ltd staff in Los Angeles are assisting the BKK Landfill Site Working Group (PRP Group) with all phases of current site management and eventual long-term remedy planning.
The BKK Landfill is a State Superfund site of more than 500 acres, and is located in West Covina, CA.
The majority of PNL’s activities encompass site assessment, monitoring and maintenance, execution of an Engineering Evaluation/Cost Analysis (EECA), plus long-term Scope of Work, remedy selection and regulatory negotiations with DTSC.
Fact Sheets and other project related documents are at http://dtsc.ca.gov/HazardousWaste/Projects/BKK.cfm.
Project Navigator, Ltd. project managers continue to assist the Ascon Landfill Site PRP Group with work on key project phases and overall site interim management and monitoring. The Ascon Site, located in Huntington Beach, CA, operated as a 38 acre waste disposal site, accepting drilling muds and associated wastes for over a 45 year time frame. PNL is simultaneously managing two major documents in the CEQA process, the remedy EIR and the Remedial Action Plan, to completion.
Project Navigator, Ltd.’s Houston, Texas office has been managing all aspects of the planning, design, and remedy construction at the Cox Road landfill site, northeast of Houston. PNL has just received notification from TCEQ that all aspects of work proposed under the Remedial Action Plan (RAP) have been completed, as described in PNL’s Response Action Completion Report (RACR) of February 2013. The site was cost-effectively capped with a clay and soil cover, and now enters a 3-year post-closure groundwater monitoring phase.
PNL’s clients are ExxonMobil, Lubrizol and US Steel. For more information on how PNL’s Houston office can assist you on environmental remediation projects, please call us at 713-468-5004.
PVNavigator contributed to the U.S. EPA’s and NREL’s recently-released (February 2013) document titled ” Best Practices for Siting Solar Photovoltaics on Municipal Solid Waste Landfills.” The document was created to provide assistance in addressing common technical challenges and identifying the benefits for siting PV on MSW landfills. PVNavigator’s graphics can be found on pages 9 and 37 of the PDF document.
PVN participated in the Oklahoma Brownfields Conference 2012 held in Oklahoma City, OK on May 22-23, 2012. Dr. Ian Webster of PNL discussed developing landfill based, PV solar power installations during an opening day plenary roundtable discussion. The panel was hosted by Robert Colangelo of Chicago’s Green Sense Radio Show. Other panelists were Marielle Boortz of Chevron Corp., Marianne Horinko, a former Acting Administrator at U.S. EPA, and Mike Sheriff Head of Generation Planning at OG&E Services.
Drs. Halil Kavak, Raudel Sanchez and Ian Webster have worked for a number of major clients on landfill assessment and closure projects. A notable example is the Operating Industries Inc (OII) Landfill in Monterey Park, CA. In addition to helping with more routine site design and construction activities, the PNL team was asked to investigate and provide solutions to control and mitigate landfill waste prism fires (or enhanced oxidation zones). The PNL team used in well thermocouples to measure temperatures and produce 3D maps of the locations of the high temperature zones. The existence of high temperature zones (driven by air intrusion into the landfill prism) affects the ability to efficiently collect landfill gas and readily maintain perimeter compliance.
The PNL team has now reported on some of the general findings. Click here to see how we have classified different types of landfill fires.
