Hazardous Waste Management

Hazardous waste management encompasses a broad spectrum of compliance functions dealing with the handling, storage, and disposal of hazardous chemicals and waste streams, as well as the determination and remediation of hazardous waste sites. These substances and situations are regulated under the Resource Conservation and Recovery Act (RCRA), the Superfund acts (CERCLA and SARA), various state environmental laws, and local ordinances.

Hazardous waste management begins with the initial purchase and storage of hazardous materials. Terranext has guided customers in the proper control of materials to comply with the "cradle to grave" requirements of RCRA. A comprehensive hazardous waste management system must address the types of materials at the facility, the storage of the materials, the potential generator of hazardous waste status, and the appropriate and documented disposal of the materials. Terranext personnel are experienced in Part B permitting, RCRA site investigations, CERCLA remediation, and emergency response.


Hazardous Waste Landfill Cover
U.S. Gypsum
Alquippa, Pennsylvania

Terranext completed a soil cover plan, schedule and cost estimate for a 160 -acre Brownfield site located near Pittsburgh, Pennsylvania for a major industrial client. The property is under an Order of Consent from the Pennsylvania Department of Environmental Protection, with whom cover options were discussed. The site was a former steel mill site which is contaminated with heavy metals and other pollutants. Various cover options were explored, including the use of treated bio-solids, and schedules and cost estimates compared for the conceptual design. The next phase of the work will include a detailed cover plan, and possible testing of various on-site cover options to determine long-term survivability. The site is scheduled to be redeveloped for an industrial use.
