Geosyntec was retained by a confidential client to remediate a 37-acre former manufacturing facility in Newark, New Jersey.
The site is a former coal tar processing facility that manufactured road tars, cresols, phenols, and cresylic acid. A proprietary in situ smoldering remediation technology was selected to remediate the site. In conjunction with the project team, Geosyntec air practitioners worked with the New Jersey Department of Environmental Protection (NJDEP) to obtain a pilot-scale operating permit because the innovative technology had not been deployed previously in a large-scale remediation project. Following success of the pilot, an air operating permit was obtained for the full-scale installation.
Geosyntec's Scope of Services
Geosyntec's air quality practitioners developed a detailed assessment of the potential air emissions from the new smoldering remediation technology based on pilot test data and analytical results. Based on the potential emissions, Geosyntec evaluated multiple emission control technologies, selected the appropriate control technology, and developed a technical specification for the air pollution control equipment to be provided to vendors. Geosyntec coordinated vendor requests for proposals and upon receipt of proposals from multiple vendors, Geosyntec provided an analysis of the vendor proposals to enable the client to select the most effective and appropriately-priced option. When the vendor was selected, Geosyntec provided oversight for the purchase, construction, and installation of the control device, a 3,000 standard cubic foot per minute regenerative thermal oxidizer (RTO). In order to obtain an air permit for the planned remediation project, Geosyntec compiled the air permit application, including a process description of the new remediation technology. Our team prepared emission calculations for the first-to-field deployment of the smoldering remediation technology and conducted a risk assessment to identify the potential off-site risk of toxic air contaminants from the remediation project. The RTO was evaluated in accordance with the NJDEP State of the Art (SOTA) requirements, similar to Best Available Control Technology, to verify that the control device could achieve the necessary emission reductions. Geosyntec prepared a perimeter air monitoring plan designed to monitor potential fugitive emissions. The plan included detailed mitigation measures to be implemented if monitoring indicated the potential for particulate matter or volatile organic compounds (VOCs) emissions off-site during site remediation activities.
Geosyntec successfully permitted the full-scale installation of a new remediation technology to meet stringent NJDEP regulatory requirements. The permitting process was completed quickly to enable the site remediation to meet an expedited project schedule. Despite the fast-track permitting, Geosyntec obtained a permit that allowed for operational flexibility while also protecting human health and the environment. Geosyntec also took the lead to revise the permit to address remedial design adjustments and changing site characteristics in very short timeframes to allow for continued clean-up of the site.
