Location: USDA-Forest Service, Beaverhead-Deerlodge National Forest Butte Ranger District, Butte, MT

Est. Contract Period: Start: 1 Oct 2010 End: 30 Dec 2011

1. General Scope of Work (SOW):

The Northern Regional Office of the USDA–Forest Service has determined that a potential threat to human health and the environment stems from the Heap Leach Facility as the result of past mining activity at the Beal Mountain mine located in Silver Bow County, Montana. The Beal Mountain Mine is located approximately 15 miles west of Butte, Montana in Sections 5 and 6, T2N, R10W and Sections 31 and 32, T3N, R10W of the Montana Principle Meridian (Attachment 1). The Site encompasses National Forest System (NFS) lands under the jurisdiction of the Forest Service, Butte Ranger District, Beaverhead-Deerlodge National Forest.

The Forest Service has completed an Engineering Evaluation and Cost Analysis (EECA) under the Comprehensive Environmental Response and Compensation and Liability Act (CERCLA) in order to develop the appropriate response action.

The Beal Mountain Mine is within the German Gulch watershed, which is part of the Upper Clark Fork River watershed. German Gulch has two main tributaries, Beefstraight Creek and Norton Creek; Minnesota Gulch is a tributary of Beefstraight Creek. German Gulch is a tributary of Silver Bow Creek. German Gulch has a 26,275-acre watershed with elevations ranging from approximately 5,300 feet at its mouth to 8,909 feet on the western divide of Minnesota Gulch.

Annual precipitation is approximately 35 to 40 inches, mostly occurring as snowfall from October through April. The area at times receives several feet of snow annually.

The Beal Mountain Mine occupies approximately 400 acres and includes two mine pits, a 116-acre heap leach facility, a waste rock dump, and the mine building containing the water treatment plant (Attachment 2). All of the mine mailto:danielmcgee@fs.fed.us� mailto:mmarks@fs.fed.us� facilities are on NFS lands. See Attachment 2 for a map showing the Beal Mountain Mine area.

There is a significant threat of a release of hazardous substances, including but not limited to, nitrate+nitrite, sulfate, copper, iron selenium and cyanide from the heap leach facility to German Gulch and other surface water and ground water.

Thus, there is a need to implement the selected removal action to repair the northern end of the heap leach area.

The removal action to be implemented under this project in whole or in part will include a grout curtain of the north edge of the Leach Pad. In addition the goal of this effort is the design and construction to repair the liner where the exploratory trenches are located and eliminate the gap between the top cover and the bottom liner (Note: both of these processes are more complex than standard earth moving operations). Additional work on this project includes removal of the Detoxification Pond (located on the southwest corner of the heap leach pad) and the Leach Pad liner in this area repaired to eliminate infiltration of precipitation into the heap leach. The final design must allow for positive drainage off of the heap leach area.

In order to accomplish this work the Forest Service, in conjunction with the selected Contractor, will need to develop a two (2) part design-build implementation process to complete the removal action at the heap leach area.

The first part of this process will be to develop a design package, including written specifications and drawings for closure of the north end of the heap leach facility and the detoxification pond. The second part of the project will be to implement the removal action according to the approved design package.

2. Request for Qualifications (RFQ):

a. Purpose

The purpose of this Scope of Work (SOW) is to outline the Two-Phase Design- Build Selection Process required for this project.

b. Objective

Prospective prime construction contractors interested in this project must respond to the following questions in Phase I no later than 27 Jul 2010

. Responses shall be limited to 15 pages.

Phase I

1) Offerors names address point of contact, phone number and email address.

2) A brief Technical Approach to this project based on the general SOW above

(not a detailed design).

3) Offerors capability to perform a contract of this magnitude and complexity (include offerors in-house capability to execute the design and construction, experience of the prime design contractor as well as any major design subcontractor experience may be submitted; comparable work performed within the past 5 years, and brief description of project, customer satisfaction, and dollar value of project) provide at least 3 examples.

4) Offerors joint venture information, if applicable, existing and potential

4) Proposal Submission, Interviews/Presentations, and Evaluations.

4. Evaluation Factors:

1) Technical approach (but not detailed design or technical information).

2) Technical qualifications:

a. Specialized experience and technical competence;

b. Capability to perform;

c. Past performance of the offeror’s team (including the architect-engineer and construction members)

3) After evaluating Phase I proposals, the contracting officer will select the three

(3) most highly qualified offerors and request that only those offerors submit Phase II proposals.
