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
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.
Terranext provided certification for the development of a Part-B permit for a hazardous waste
TSD solvent recycling center in Columbus, Georgia. Services included an engineering
assessment of the suitability of secondary containment for a hazardous waste drum storage
area and above ground storage tank area. Project was performed under a limited time schedule
to meet regulatory requirements.
Project Value was $2,500.
Hazardous Waste Remediation
Houston, Texas CERCLA NPL Site
Terranext designed, pilot tested, installed, and operated a plant to remove arsenic from groundwater
prior to discharge to Houston's POTW. Plant used FeCl precipitation, solids liquid separation
(clarifier with filter press), and discharge of water to POTW. FeCl addition was balanced to insure
solid were not a hazardous waste (TCLP).
Project Value was $250,000.
