Hazardous Waste and Superfund Projects

Releases or threatened releases of hazardous substances, and the management of hazardous wastes, are subject to a complex web of EPA regulations issued under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA, also called Superfund) and Subtitle C of the Resource Conservation and Recovery Act (RCRA). SCS Engineers provides expert regulatory compliance and remediation assistance to our clients. Our professionals understand the regulations and what they mean to your business.

Superfund addresses uncontrolled releases or spills of hazardous substances. SCS Engineers can help your business during each phase of the Superfund process, from identification and preliminary assessment through screening investigations, comments on proposed listings, remedial investigations, feasibility studies, remedial design, construction engineering, and long-term operation and maintenance.

SCS’s Superfund experience includes several solid waste landfills on the National Priorities List. Landfill sites present numerous challenges for the Superfund program, and our professionals are experts in the unique problems associated with these sites.

It is better — and significantly less expensive — for a potentially responsible party (PRP) to take control of the remedial investigation/feasibility study (RI/FS) process, rather than to allow the EPA or the state to conduct the RI/FS. By retaining a qualified consultant like SCS Engineers, PRPs can select, design, and implement a cost-effective remedial action. We help PRPs control the RI/FS process and keep it focused.

Providing long-term site operation, maintenance, and monitoring of environmental control systems, including those at Superfund sites, is a specialty of SCS Engineers. These services can help your business construct, operate, and maintain a remedy less expensively than if government agencies and their contractors perform the work.

Disputes often arise between PRPs over their respective share of liability for a contaminated site. Properly allocating response costs often requires historical and forensic research to assess the impact of each PRP’s activities on the site. SCS is experienced in providing cost allocation support to PRP groups.

Toxics Release Inventory Reporting

Authorized under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Pollution Prevention Act (PPA), the Toxics Release Inventory (TRI) tracks the management of certain toxic chemicals that may pose a threat to human health and the environment.

Some industries, manufacturers, including food and beverage, electric utilities, and mining facilities, may need extra time this year to comply with recent rule changes related to per- and polyfluoroalkyl substances (PFAS).

TRI is a two-step process, and covered facilities with at least ten full-time equivalent employees must complete the first step to evaluate whether a report is required each year. For each chemical that exceeds a reporting threshold, EPA requires the facility to calculate releases to the air, wastewater, and stormwater and the amount of the chemical recycled or treated on-site or sent off-site for treatment during the previous calendar year.
