Subject: Interim Remedial Action Report, Eastland Woolen Mill Superfund Site, 

Corinna, Maine, received August 18, 2008 and Operational & Functional 

status concurrence 

Dear Mr .^^.iWEnaway: 

The Maine Department of Environmental Protection (MEDEP) has reviewed the Interim 

Remedial Action Report, Eastland Woolen Mill Superfund Site, Corinna, Maine. Nobis 

Engineering, Inc. (Nobis) submitted the report to the MEDEP on August 18, 2008. 

MEDEP's review comments are listed in Attachment A to this letter. 

Additionally, as you know, on August 4, 2008, we, along with a representative from 

Nobis, conducted a remedial action pre-final inspection. The MEDEP concurs that no 

construction punch-list items were identified during the inspection and, therefore, 

the inspection is also considered the final inspection. 

Further, based on MEDEP's Interim Remedial Action Report review and our August; 4, 

2008, inspection, MEDEP understands that the 2006 Amended ROD selected remedial action 

for the site has been implemented and has attained "operational and functional" status 

as defined by the NCP. Therefore, MEDEP concurs that the remedy is Operational and 

Functional and that the 10 year period for the Long-Term Response Action has begun. 

I look forward to working with you as the remedial cleanup continues at this site. If 

you have any questions in regards to this letter, please call me directly at (207) 

287-8554 and at (207) 287-2651.

Attachment A 

Genera l Comment: The report summarizes activities/actions conducted at the site 

from discovery, removals, NPL listing, RI/FS to implementation of the remedial 

action. Numerous wells (drinking water, monitoring, injection, etc.) existed or 

were installed and utilized throughout the investigation and cleanup activities. 

A table containing a master listing/inventory of all the wells installed and 

utilized over time at the site that also presents the type (monitoring, injection, 

drinking water, etc.) and the status (decommissioned, active, inactive, etc.) of 

each listed well needs to be developed and included in this document.

Treatment), 2"'' paragraph, 7"^ sentence: Amend the text to read, "The NTCRA soil 

cleanup standards are included in Table 2." The groundwater cleanup levels 

presented in Table 2 were used for the in-situ chemical oxidation activities 

(ISCO). [Please note that during the NTCRA the soil cleanup levels presented in 

Table 2 were used for the soil and extracted groundwater was treated to meet 

levels for surface water discharge that have been presented in past NTCFIA 

documents in a table titled "Treated Effluent Surface Water Quality Discharge 

Criteria". The "Groundwater Cleanup Level" levels presented in Table 2 of this 

document were established for the remedial action and originate from "Table 22 -

Interim Groundwater Cleanup Levels" of the September 2002 Record of Decision 

(2002 ROD) document. The 2002 ROD Interim Groundwater Cleanup Levels were used 

for the ISCO activities conducted as part of the NTCRA.]
