The purpose of the cap is to limit infiltration through mine waste remaining after historical copper mine operations performed on the property. The mine waste consists of rock and rock-amended sediment previously consolidated

and graded as part of recent and ongoing Superfund remediation activities. The expected components of the composite cap include in order from the surface: 12 inches crushed stone (3-inch minus), geocomposite drainage layer, 60-mil textured geomembrane (seam welded), and geofabric. All crushed stone will be sourced from onsite and imported granular material will not be required. Other activities to be performed under this contract may include installation of drainage features (e.g., swales, culverts, etc.), grading, seeding and stabilization of disturbed areas outside stone cover system, rock crushing, stockpile management, and wetland improvements.

The Site is located approximately 15 miles west of the town of Blue Hill and 35 miles west of the town of Bar Harbor on the northwest side of the Cape Rosier peninsula on Penobscot Bay. The Site includes the former Callahan Mine property, an elongated 120-acre property oriented north-south and accessed from Goose Falls Road. Goose Pond and Holbrook Island Sanctuary State Park are immediately east of the Site. Private residences and seasonal homes are located adjacent to the Site on Goose Falls Road and Cape Rosier Road.From 1968 through 1972, the Callahan Mining Corporation developed a massive sulfide ore body located beneath a bedrock peninsula that extended into Goose Pond. To gain access to the ore, Goose Pond was drained by constructing two dams: an earthen dam across Goose Pond (Marsh Creek) near the southern Site boundary and a concrete dam with stop logs at Goose Falls. After draining the pond, an open pit mine approximately 600 feet in diameter and 300 feet deep was excavated to access the ore. Approximately five million tons of waste rock and approximately 800,000 tons of ore-bearing rock were mined from the open pit mine.Additional information about the Callahan Mine Superfund Site is available here: www.epa.gov/superfund/callahan.Responses:In order that we may assess your capability to perform this contract adequately, interested firms should submit a capabilities package to include, at the minimum, the following:Firm’s name, address, point-of-contact, phone number, email address, CAGE and SAM.gov Unique Entity Identifier.Business classification (e.g., small business, veteran-owned small business (VOSB), Service-disabled veteran-owned small business (SDVOSB).A description of the firm’s in-house capabilities to accomplish the above stated work requirements and how the firm will meet or exceed the requirements for Federal Acquisition Regulation (FAR) 52.219-14 “Limitations on Subcontracting”.
