Item Open Access Ajax/Magnolia project(2002-12) Umatilla National Forest (Agency : U.S.); North Fork John Day Ranger District (Or.); EA Engineering, Science, and Technology, Inc.; Millennium Science and Engineering, Inc.Contains several documents, including abbreviated preliminary assessments of each of the Ajax and Magnolia mines, a site inspection of the two mines, a public participation plan, and an engineering evaluation/cost analysis (EE/CA of the mines, as well as earlier material on clay mineralogy and a sample data summary package. After screening of the waste piles with the Niton XRF unit, the proximity to Lucas Gulch and EPA's APA checklist, both Ajax and Magnolia were recommended for Site Inspection (SI) in the Abbreviated Preliminary Assessments. The SI found high concentrations of metals in the adits and retention ponds of both mines, with rock piles and soil contaminated from AMD, with arsenic migrating downstream from the Magnolia site to the onsite stream station at Ajax Mine. After an EE/CA was recommended, a Public Participation Plan was created and a list of recipients drawn up. Finally, an EE/CA was performed for a proposed CERCLA removal action for the two inactive gold mines. Seventeen metals were found to be ecological threats, some of which threatened spawning and rearing and the migratory pathways of federally-listed bull trout and steelhead, and arsenic created a threat to child recreationists and adult workers. Proposed alternatives include excavation and onsite disposal and adit discharge treatment.Item Open Access Falls/Meadowbrook final environmental assessment(2007-04-13) North Fork John Day Ranger District (Or.)Proposes to commercially cut approximately 6,327 acres, non-commercially thin 469 acres and landscape burn up to 7,130 acres to reduce live tree stocking, alter stand structure and species composition, and reduce future fire severity.Item Open Access Flat timber sale decision memo(2007-05-20) North Fork John Day Ranger District (Or.)Announces that commercial thinning will be used to harvest approximately 140 MBF from 69 acres located along less than one mile of Forest Roads 5916-088 and 5916-085. Treatment will improve sustainability and promote stand vigor by reducing competition for light, nutrients, and moisture; encourage healthy stands with species compositions within the range of natural variability; reduce the probability of epidemic level infestations of insects and disease; and reduce ladder fuels thereby lessening the likelihood of high intensity fires.Item Open Access Granite area mining projects draft environmental impact statement(2002-06) North Fork John Day Ranger District (Or.)Proposes to approve 16 plans of operation for mining claims located within the Granite watershed. Key issues include the effects continued mining would have on the water quality of Granite and Clear Creeks, listed on Oregon's 303(d) list of impaired waters, and their tributaries, as well as the threat to bulltrout, redband trout and anadromous fish species in poor to fair habitat conditions. Alternative actions call for minimizing adverse environmental impacts, gating Forest Service Road 1035-012, and decommissioning two other roads totaling 2.25 miles.Item Open Access Hidaway allotment management plan final environmental assessment, decision notice and finding of no significant impact(2007-07) North Fork John Day Ranger District (Or.); Wallowa-Whitman National Forest (Agency : U.S.)EA proposes to reauthorize livestock grazing and implement protective measures for sensitive plants and improved livestock distribution. Includes improving or maintaining upland vegetation conditions and allowing for forage utilization by modifying current grazing practices, as well as improving riparian vegetation by fencing portions of two streams. Decision notice announces implementation of Alternative 3 of project EA, allowing 493 cattle to graze between June 16th and September 30th.Item Open Access North Fork John Day Wild and Scenic River management plan environmental assessment, decision notice and finding of no significant impact(1993-06) North Fork John Day Ranger District (Or.); Baker Ranger District (Or.)Proposes to develop a management plan that will address resource protection, development of lands and facilities, user capacities, and other management practices necessary or desirable to achieve the purpose of the Act. Decision notice announces implementation of Alternative D with modifications of project EA, which gives special emphasis to high level management of water quality and fisheries concerns (habitat of the wild runs of chinook salmon, steelhead, and resident redband/rainbow trout and bull trout), and allows for coordination with appropriate state and federal agencies, Indian tribes, and landowners.Item Open Access Potamus ecosystem analysis(2004-12) Heppner Ranger District (Or.); North Fork John Day Ranger District (Or.)Provides analysis of historic and current physical and biological conditions of the watershed. Hydrology concerns include maintaining and improving adequate water supplies, maintaining and restoring water quality, and improving overall conditions of streams, floodplains, and riparian ecosystems. Other topics include aquatics, upland forest vegetation, wildfire risk, botanical resources, noxious weeds, vertebrates, fire and fuels, non-forest vegetation, and rare plants.Item Open Access Skull timber sale decision memo(2007-05-20) North Fork John Day Ranger District (Or.)Announces decision to commercially thin 170 MBF from 70 acres along 1-2 miles of Forest Roads 5209 and 5209-916 in order to improve sustainability and promote stand vigor by reducing competition for light, nutrients, and moisture; encourage healthy stands with species compositions within the range of natural variability; reduce the probability of epidemic level infestations of insects and disease; and reduce ladder fuels to lessen the likelihood of high intensity fires.Item Open Access Tower Fire ecosystem analysis forest vegetation report and forest vegetation BAER report(1997-01) North Fork John Day Ranger District (Or.); Powell, David C.; Erickson, VickyVegetation report analyzes impact of fire on pre-fire forest cover types and examines potential natural vegetation and current conditions. Recommendations consider free salvage, natural regeneration, artificial reforestation, thinning, understory removals, prescribed burning, fertilization, and pruning. BAER (burned area emergency rehabilitation) report is designed to alleviate emergency watershed conditions following wildfire to help stabilize soil, control water, sediment, and debris movement, and prevent threats to life, property, and other downstream values, both on-site and off-site. Recommends that the District acquire high-resolution (2-meter) color infrared (CIR) photography for the fire area, that the burned plantations be replanted as quickly as possible, that the remaining areas with a high amount of stand mortality be rescheduled for planting, that all plantings emphasize establishment of early-seral conifers on upland sites, and that future stand densities by maintained at levels which minimize the potential for crown fires.
