Pre-Solicitation Notice - Ely Copper Mine Superfund Site, Vershire, VT

NAICS Code:

562 -- Waste Management and Remediation Services/562910 -- Remediation Services

Synopsis:

The U.S. Army Corps of Engineers, New England District will be issuing a Request for Proposal for a Single Award Task Order Contract (SATOC), Indefinite Delivery/Indefinite Quantity (ID/IQ) contract for Remediation Services at the Ely Copper Mine Superfund Site in Vershire, Vermont. The total acquisition value of the contract awarded under this solicitation is not to exceed $40,000,000 and will have a five-year ordering period. This will be a Small Business Set-Aside, Best Value Trade-off award. The NAICS code for the work is 562910 (size standard is 1,000 employees).

The Project Site, The Ely Copper Mine, is an abandoned copper mine located in Vershire, Orange County, Vermont and encompasses approximately 350 acres where historic mining activities took place. This includes about 30 acres of waste material containing an estimated 172,000 tons of waste rock, tailings, ore roast beds, slag heaps and smelter wastes. The Site also includes over 3,000 linear feet of Underground Mine Workings along with the associated shafts and adits. No buildings remain at the Site. Remnant foundations, pads, and stone walls, including a 1,400-foot-long smoke flue, demark the location of the former Site structures including a former flotation mill and the smelter plant. The contemplated work under the initial task order is associated with Operable Units (OU) 1, 2 and 3. OU1 includes areas that are the primary source of the surface water and sediment contamination to Ely Brook, Pond 4, Pond 5 and Schoolhouse Brook. OU2 includes the Underground Workings on the southern side of Dwight Hill and approximately 12 shafts, adits, vents or other openings. OU3 includes the Underground workings on the northern side of Dwight Hill. There are no surface features in OU3. If the EPA executes a Record of Decision for OU4, the remedy will include stream restoration and capping of the smelter area.

The selected remedy for OU1 is a comprehensive approach that addresses all current and potential future risks caused by contaminated soil, waste rock, tailings, surface water, and sediment in the OU1 area of the Site. Specifically, this remedial action includes: the excavation of about 107,000 cubic yards (cy) of contaminated waste rock, soil, and sediment with the consolidation of this material under a cover system in an on-site containment cell; and the excavation of about 4,000 cubic yards of contaminated tailings from the Tailings Area (TA) and consolidation under a cover system.

The selected remedy for OU2/OU3 includes a passive surface water treatment system to treat the discharge from the Main Adit without changing the air flow in the Main Shaft and the permanent closure of the Deep Adit by filling in-place with grout and/or flowable fill to reduce or eliminate Acid Mine Drainage (AMD). The other mine features will be filled unless they are determined to be hibernacula for the state- or federally listed threatened or endangered bats.

All work will be performed in accordance with CERCLA, the OU1 Record of Decision signed in September 2011, the OU2/3 Record of Decision signed in June 2016, and the OU1 Explanation of Significant Differences signed in September 2019, and EPA green and sustainability principles.

This is not a request for proposals at this time. The solicitation requirements and contract documents to include instructions for submission and the response date will be available on or about October 4, 2023. Contract award of the Base ID/IQ Contract and Seed Task Order is scheduled for April 2024 with Seed Task Order construction completion in 2026. Award will be made to the offeror demonstrating the best value to the Government, taking into consideration the stated evaluation factors such as qualifications, experience, past performance on similar projects, and cost/price, as well as their respective weightings as specified in the solicitation. Specific instructions and evaluation factors will be provided in the solicitation.
