SUMMARY DESCRIPTION OF PROPOSED PROJECT (UNCHANGED):

The Formosa Mine Superfund site is an abandoned mine located in southwest Oregon in Douglas County. Locally, it is situated in the Coast Range Klamath Mountains at elevations between 3,200 and 3,700 feet (ft) above mean sea level (amsl) on Silver Butte Peak (3,973 ft amsl).

The project scope of work consists of activities necessary to implement primarily the earthwork-related requirements of the EPA’s Record of Decision for the Formosa Mine Superfund Site Operable Unit (OU) 1. OU1 includes all surface and subsurface mine materials deposited outside of the underground mine workings and considered "source materials" for the Site. These include materials excavated during construction and operation of the mine such as waste rock, ore, tailings, construction rock, road surfaces, and contaminated soils. The objectives of the OU1 remedial action are to remove, consolidate, and restrict or minimize the interaction of contaminant source materials with precipitation, surface water runoff, and groundwater. The remedial approach focuses on preventing direct exposure to mine waste with elevated concentrations of metals and reducing acid rock drainage (ARD) generation, thus, reducing impacts to groundwater and surface water. The remedial action includes OU1 mine materials at the encapsulation mound (EM); former ore storage/million-gallon storage tank area; the Formosa Adit 2, Formosa Adit 3, and 1090 Raise waste rock dumps (WRDs); and roads containing mine materials adjacent to these areas.

The specific project scope of work includes the following actions:

• Stabilizing the steep encapsulation mound (EM) slopes with gabion walls;
• development of a clean materials borrow area and non-primary mine disturbance area (PDMA) mine material repository;
• grading and consolidation of mine materials in the non-PMDA mine material repository;
• impermeable cover construction on the EM, former ore storage/million-gallon storage tank, and non-PMDA mine material repository;
• grading, amendment and revegetation of mine materials at the area southwest of the EM, and Formosa Adit 2, Formosa Adit 3, and 1090 Raise waste rock dumps (WRD)s; and
• excavation of mine materials from roads, reconstruction of roads within the project limits, and construction of a steep slope northwest (NW) access road for gabion wall placement.
