1 Superfund Site Textile Mill 25 miles northwest of Bangor, Maine Wool products Fabric finishing and dying Dye-aid Chlorobenzene, Dichlorobenzene (1,2; 1,3, and 1,4), and Trichlorobenzene (1,2,4 and 1,2,3) Operations began in 1912 acquired mill in 1936 Major employer for Town Background Information Mill closes in 1996 Stores began to close Sewer system and water system dependent upon Mill Major hit to tax base Maine DEP initiates cleanup to remove solid and liquid waste from mill in 1996 Town considers options for next steps Background Information Background Information Town of Corinna deliberated whether to seek a Brownfield grant or request Superfund designation Brownfields Grant to deal with investigation Cleanup resources would need to come from another source Local control Redevelopment focus Superfund Perception Lose control to federal government Cannot control outcome Cleanup focus Can Town be liable? They took Mill property due to unpaid taxes Requires support from Governor prior to placement on National Priorities List (NPL) Must complete the Hazard Ranking Process and exceed a score of

2 Background Information Town Officials and local citizens met with EPA in 1998 Discussion focused on Brownfields vs Superfund NPL EPA explained its commitment to local input and consideration of reuse as part of revitalized Superfund program EPA also agreed to consider a dual track SACM model for the site Determine if initial removal action is appropriate while completing the overall investigation program EPA initiates removal evaluation in December 1998 EPA signs Action Memorandum to initiate a Non-Time-Critical Removal Action (NTCRA) in July 1999 EPA adds site to NPL in July 1999 Two components of cleanup Stakeholder involvement Local input Re-use focus Planning and implementation of cleanup Critical area of overlap was the design phase Integrate local and other stakeholders input Resolve divergent interests in a timely manner How was it done? EPA provided Redevelopment grant for the development of a re-use plan EPA provided a Technical Assistance Grant EPA met regularly with stakeholders and provided input to re-use plan State Agencies were fully involved and invested in reuse EPA s design consultants and implementation contractors were also committed to these themes Examples of reuse integration into cleanup Historic resources Odd Fellows Building Road re-alignment and bridge replacement River restoration Site grading and restoration Groundwater cleanup 2

3 Moving Odd Fellows Hall Historic resources Odd Fellows Building Eligible for National Register of Historic Places Foundation over river Town wanted to save Cleanup plan required excavation beneath structure EPA, State Historic Preservation Office, Town of Corinna Town offered a new lot EPA could move once Road Re-Alignment Road re-alignment and bridge replacement EPA needed to relocate the road and remove bridge Town and State wanted a permanent realignment EPA redevelop grant helped provide vision and framework Town and Maine DOT acquired property and resolve logistical issues EPA only had to move road and bridge once rather than twice 3

4 River Restoration River restoration Dam beneath mill and shallow pond behind dam EPA had to remove dam Town, State of Maine (DOT, DOC, IFW, DEP), and EPA evaluated options Return to unrestricted flow No dam maintenance Fish passage Community Resource River Restoration Town boardwalk trail along restored river Site grading and restoration EPA considered the original Town re-development plan Developed revised figure based on updated subdivision and re-use plan Developing grading plan to match re-use plan Town installed utilities and roads in conjunction with EPA work Completed back section of site early to allow for construction of Senior Housing 4

5 Groundwater Cleanup EPA cleanup included long-term pump and treat system Permanent facility in downtown middle of re-use area Town and re-use committee requested that EPA re-consider Technical information from design and early implementation indicated that system need only be temporary EPA changed remedy in September 2006 Cleanup involved innovation and innovative technology Treatment system Site Characterization In-situ Remediation Treatment System Design to have minimal stand-by costs Low-temperature thermal steam stripping Adapt to phased funding Pre-excavated and screened soil stockpile 5

10 Summary Local input and re-use are critical elements of Superfund project management Obtaining early and substantial stakeholder involvement can greatly increase value of cleanup to community Project Team must integrate re-use and other local input with main focus cleanup Not just the federal and state agencies: Investigation, design, and implementation consultants and contractors are a vital part of the team Be prepared to adapt to funding, schedule, and other changes 10
