On February 28, 2022, the Maine Department of Environmental Protection (MEDEP) hazardous waste management unit was asked by the Town of East Millinocket to investigate reports that hazardous waste was stored outside the former paper mill’s boiler house. On March 29, 2022, MEDEP visited the Boiler House to evaluate the condition of the containers. Based on its observations, MEDEP had concerns about the quantity and condition of the seemingly abandoned containers.  On March 31, 2022, MEDEP requested that EPA evaluate the Boiler House for a potential time-critical removal action under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).  


On May 25, 2022, EPA and its Superfund Technical Assessment and Response Team (START) contractor conducted a site walked with MEDEP, the town, Katahdin KI 50, LLC (the prior and/or current owner) and Karma Environmental (a contractor) to investigate the Boiler House portion of the former mill property and upon request, the Chemical Storage Building, adjacent to the former Recycle Fiber building, as well.


From June 27 - 28, 2022, EPA and START performed preliminary assessment/site investigation (PA/SI) sampling activities. START collected a total of 24 solid and liquid samples from various containers, including ASTs, 250-gallon totes, 55-gallon drums, wrangler boxes, and 5-gallon containers. These samples were delivered to the EPA New England Regional Laboratory for volatile organic compounds (VOCs), PCB, pH, and flashpoint analyses.  In addition, START collected 5 bulk samples of suspected asbestos containing materials for asbestos analysis.


The June 2022 PA/SI sampling results have documented the presence of corrosive acids and bases, and VOCs such as naphthalene.  Based upon site conditions documented during the PA/SI and sampling results indicating presence of hazardous substances in abandoned containers, the Site Investigation Closure Memorandum, dated August 23, 2022, recommended that a time-critical removal action be performed to address the threat of release of hazardous substances.
