Bald Angel vegetation management decision notice/FONSI
(2007-02-22) La Grande Ranger District (Or.)
Announces decision to implement Alternative 3 of the project EA, emphasizing retention of critical high quality cover and connective corridor areas to provide cover and connectivity habitat while other overstocked stands are treated to accelerate development of long-term landscape cover and large structure needs.

Blue Mountain land exchange -- Oregon final environmental impact statement
(2006-09) Malheur National Forest (Agency : U.S.); Umatilla National Forest (Agency : U.S.); Wallowa-Whitman National Forest (Agency : U.S.)
Analyzes proposed assembled land exchange between Clearwater Land Exchange-Oregon and the Forest Service, involving acquiring and conveying within the Malheur, Umatilla, and Wallowa-Whitman National Forests. Plans to provide for more efficient cost effective management of Forest lands through consolidation, and to acquire and protect habitat for Threatened and Endangered species and lands within Congressionally Designated Areas. Concerns include exercise of American Indian treaty rights and cultural uses, water quality, fisheries, old growth associated species, and social and economic environment.

Buffalo Mine abbreviated preliminary assessment
(2008-08) Wallowa-Whitman National Forest (Agency : U.S.)
Assesses mine site on moderately steep side slopes, consisting of two adits, associated wasterock and tailing ponds, one with water treatment facilities and miscellaneous buildings. A Niton XLt unit found that all metals at the site exceeded screening criteria for birds, invertebrates, and plants, but only arsenic (13.13 to 338 mg/kg) exceeded EPA Region goals. The site has been given a Low Priority for any future site assessments.
Open Access
Cap Martin complex abbreviated preliminary assessment
(2006-08) Wallowa-Whitman National Forest (Agency : U.S.)
Assesses site consisting of four collapsed adits, one of which has water discharge, and 6000-80000cy of wasterock materials, most of which is adjacent to Granite Creek. There are numerous trenches and apparent hydraulic mining in the area as well as possible historic dredging operations, with one old log cabin and another apparently collapsed cabin. A Niton XLt unit found that most metals at the site exceeded screening criteria for birds, invertebrates, and plants, but only arsenic (60 to 105.6 mg/kg) exceeded EPA Region goals. The site has been given a High Priority for further assessment.

Golden Fraction abbreviated preliminary assessment
(2006-08) Wallowa-Whitman National Forest (Agency : U.S.)
Assesses site consisting of a large collapsed adit and approximately 3000cy of wasterock material adjacent to Granite Creek. A Niton XLt found that most metals at the site exceeded screening criteria for birds, invertebrates, and plants, but only arsenic (50.79 to 76.5 mg/kg) exceeded EPA Region goals. Since the wasterock forms part of the embankment for Granite Creek, the site has been given a High Priority for further site assessment.
Open Access
Granite Creek Mine #5 abbreviated preliminary assessment
(2006-08) Wallowa-Whitman National Forest (Agency : U.S.)
Assesses mine site consisting of a large collapsed adit and approximately 500cy of wasterock material adjacent to Granite Creek, with numerous trenches and apparent hydraulic mining. A Niton XLt unit found that most metals at the site exceeded screening criteria for birds, invertebrates, and plants, but only arsenic (59.7 mg/kg) exceeded EPA Region goals. Since the wasterock forms a part of the embankment for Granite Creek, the site has been given a High Priority for further site assessment.
Open Access
Granite Creek Mine #6 abbreviated preliminary assessment
(2006-08) Wallowa-Whitman National Forest (Agency : U.S.)
Assesses mine site consisting of a large collapsed adit and approximately 1000cy of wasterock material, which is adjacent to a small ephemeral tributary to Granite Creek. A Niton XLt unit found that most metals at the site exceeded screening criteria for birds, invertebrates, and plants, but only arsenic (7.16 mg/kg) exceeded EPA Region goals. Further site assessment was not warranted.
Open Access
Granite Creek Mine #7 abbreviated preliminary assessment
(2006-08) Wallowa-Whitman National Forest (Agency : U.S.)
Assesses mine site consisting of a large collapsed adit and approximately 700cy of wasterock material adjacent to Granite Creek, with numerous trenches stemming from hydraulic mining and possible historic dredging operations. A Niton XLt unit found that most metals at the site exceeded screening criteria for birds, invertebrates, and plants, but only arsenic (79 mg/kg) exceeded EPA Region goals. The site has been given a High Priority.

Granite Creek Mines human health and ecological risk assessment
(2006-04) Wallowa-Whitman National Forest (Agency : U.S.); Cascade Earth Sciences
Assesses, through a streamlined risk assessment process, potential human health and ecological risks associated with mining-related contamination at the Monumental, Cap Martin, Sheridan, Tillicum, and Central Mines (collectively called Granite Creek Mines). Arsenic and lead were identified as contaminants with carcinogenic risk predicted from exposure to arsenic-impacted surface water and soil/wasterock. Soil and wasterock threaten ecological impacts for primary plants and terrestrial invertebrates, and surface and pore water similarly pose a threat to aquatic life and wildlife. An Engineering Evaluation/Cost Analysis (EECA) is recommended, along with a data gap investigation.

Granite Creek Mines site inspection
(2004-01) Wallowa-Whitman National Forest (Agency : U.S.); EA Engineering, Science, and Technology, Inc.
Documents Site Inspection performed by EA Engineering at five Granite Creek Mines: Monumental, Cap Martin, Sheridan, Tillicum, and Central. The objectives were to access the immediate or potential threat posed by wastes at the site to human health and the environment, and to collect information to support a CERCLA decision, including background research and file review; onsite and offsite reconnaisance; and collection and analysis of soil, waste, surface water, pore water, sediment, plant tissue, and benthic macroinvertebrate samples. Based on the elevated concentrations of metals detected in onsite soil and waste rock samples at all five mine sites, as well as onsite surface water samples collected at the Monumental Mine, an Engineering Evaluation/Cost Analysis (EE/CA) is recommended.

Granite Creek Tributary Mines initiation of CERCLA investigation memorandum
(2007-02-20) Wallowa-Whitman National Forest (Agency : U.S.)
Documents, pursuant to the Guidelines of the National Oil and Hazardous Substance Contingency Plan (NCP), the decision to initiate a CERCLA investigation in nine locations at the Granite Creek Tributary Mines site. A Site Inspection has determined that a hazardous release has occurred, and a human health and ecological risk assessment has been performed and acceptable exposure has been exceeded. Identifies possible threats to nearby human populations, animals, the food chain, soils, and drinking water.

(2003-07-21) Wallowa-Whitman National Forest (Agency : U.S.)
FEIS analyzes five alternatives seeking to make management, utilization, and disposal of natural resources compatible with the HCNRA Act. Record of decision announces selection of the preferred Alternative E-modified, which continues the management direction in the Forest Plan, but with specific changes designed to address the need for change. Includes emphasizing maintaining the rustic and primitive nature of the area while restoring the natural role of fire and maintaining vegetative conditions within HRV.

Joseph Creek rangeland analysis final environmental impact statement and record of decision
(2005-09-23) Wallowa Valley Ranger District (Or.)
FEIS reviews proposed activities to allocate forage for commercial livestock grazing on eleven allotments near Joseph Creek. Record of Decision announces implementation of Alternative 3 modified of the project FEIS, which would authorize grazing using an adaptive approach to grazing management while implementing specific protections for sensitive areas.
