CERCLA-Removal-and-Closure-Actions4

In 2011, Trihydro was retained by a group of 17 Potentially Responsible Parties (PRPs) to complete waste removal and decontamination activities at a closed industrial site in Indiana. Before entering bankruptcy in 2010, the facility owner was using the site as a centralized water treatment facility for commercial used oil and wastewater processing. Trihydro provided environmental services as outlined in an Administrative Settlement and Order on Consent (ASAOC) negotiated with United States Environmental Protection Agency (USEPA) Region V following a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) removal and decontamination action.

A number of process chemicals and wastes had accumulated and were being stored at the facility, including recycled oils; oily sludges, including oily polychlorinated biphenyl (PCB) contaminated-sludge wastewater; caustic soda; hydrogen peroxide; and sulfuric acid. The project included managing and disposing of more than 5 million gallons of stormwater runoff from the facility, and removing and disposing of 536,000 gallons of bulk liquid wastes and over 8,000 tons of stabilized wastes, along with the cleaning of more than 5 miles of interconnected process piping. Trihydro coordinated with more than 50 stakeholders, assisted with community relations efforts, and prepared the final closure document for the PRPs’ release from further environmental requirements.

The project had multiple stakeholders, including PRPs and their legal representation; federal, state and local regulatory officials; and an active community interest group.  Trihydro used Project Direct© as a single online clearinghouse for analytical data, daily progress reports, site photographs, and draft document collaboration/distribution. By establishing several levels of access permission, Trihydro was able to allow PRPs direct online access to all relevant site and project information. PRPs were also able to collaborate and provide review comments on draft reports/status memoranda.  Regulatory officials were only provided access to daily site activity summaries, final documents, and the photograph repository. Select members of the community interest group were provided online access to weekly work summaries and planned activities.  The use of Project Direct© in this manner allowed more than 50 individual stakeholders to remain informed on project developments and apprised of project milestones.
