Kitzhaber, l\lD., Governor (503) 229-5696 TTY (503) 229-6993 September 24, 2002 Roy Sprout City of Creswell PO Box 276 Creswell, Oregon 97426 RE: Source Water Assessment Report City of Creswell PWS # 4100246 Dear Mr. Sprout: Enclosed is the Source Water Assessment Report for the surface water potiion of City of Creswell's drinking water protection area. A source water assessment report for the groundwater supply will be addressed in a separate report. The assessment was prepared under the requirements and guidance of the Federal Safe Drinking Water Act and the US Environmental Protection Agency, as well as a detailed Source Water Assessment Plan developed by a statewide citizen's advisory committee here in Oregon over the past two years. The Department of Environmental Quality (DEQ) and the Oregon Health Division (ORD) are conducting the assessments for all public water systems in Oregon. The purpose is to provide information so that the public water system staffloperator, consumers, and community citizens can begin developing strategies to protect your source of drinking water. The drinking water intake forthe City of Cottage Grove and London Water Co-op public water systems are located upstream of the Creswell intake. This source water .assessment addresses the geographic area providing water to Creswell's intake (Creswell's portion of the drinking water protection area) between Creswell's intake and the upstream intakes for Cottage Grove and London Co-op.

  • REDACTED Community Involvement Plan
    Community Involvement Plan for Black Butte Mine Staying informed and involved Cottage Grove Lake 1/15/2013 United States Environmental Protection Agency Community Involvement Plan for Black Butte Mine Lane County, Oregon This is the U. S. Environmental Protection Agency’s (EPA) plan for involving community members in the investigation and cleanup of the Black Butte Mine Superfund Site. During the summer of 2012 EPA talked with residents, community groups, Lane County and City of Cottage Grove officials, Oregon Department of Environmental Quality (ODEQ) and US Army Corps of Engineers (USACE) staff and other interested people to find out how they wanted to be informed and involved. We welcome your input and ideas for improving our community outreach at any time. EPA is doing an environmental investigation at the Black Butte Mine Superfund Site, located in the headwaters of the Coast Fork Willamette River, approximately 10 miles southeast of Cottage Grove, Oregon. Studying the nature and extent of contamination, and evaluating cleanup alternatives with a feasibility study will take several years. EPA will build on extensive work already completed by ODEQ and other researchers. Community involvement will play an important role as we complete the investigation and cleanup of mercury and other contamination at the Black Butte Mine. Understanding community priorities, issues and concerns can help EPA make informed decisions to create a cleanup plan that meets the needs of the community. This plan includes the following: EPA Contacts Site Description

  • First Amendment to the Action Memorandum for a Non-Time
    UNITED STATES ENVIRONMENTAL PROTECTION AGENCY REGION 10 1200 Sixth Avenue, Suite 900 s9, tt 11JW1-s140 OFRCEOF ENVIRONMENTAL CLEANUP SUBJECT: First Amendment to the Action Memorandum, including a Request for Exemption from the 12-Month and $2 Million Statutory Limits on Removal Actions and an Increase in the Project Cost Ceiling for a Non-Time-Critical Removal Action for the Furnace Creek Area at Operable Unit 1 of the Black Butte Mine Superfund Site, Lane County, Oregon (SEMS ID No. 0ROOOOS15759) · FROM: Dave Tomten, Remedial Project Manager Site Cleanup Unit 2, Idaho Operations Office THRU: Davis Zhen, Unit Manager Site Cleanup Unit 2, Office of Environmental Cleanup Cami Grandinetti, Program Manager Remedial Cleanup Program, Office of Environmental Cleanup TO: Sheryl Bilbrey, Director Office of Environmental Cleanup I. PURPOSE The purpose of this First Amendment to the Action Memorandum (AM) is to request and document approval of a non-time-critical removal action (NTCRA) described herein for the Furnace Creek Area at Operable Unit (OU) 1 of the Black Butte Mine (BBM) Superfund Site (Site). This NTCRA involves the excavation of mercury-contaminated sediment/soils within the Furnace Creek drainage and placement of the excavated materials in an onsite repository within OUl. This AM is based on the engineering evaluation/cost analysis (EE/CA) and public comments received pursuant to 40 CFR §300.41S(n)(4)(iii) of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The initial Action Memorandum was approved on 27 June 2007 to perform a time-critical removal action (TCRA) to mitigate exposure pathways to mine-waste-contaminated soils and sediments and reduce sediment loading in Dennis and Furnace Creek (EPA 2007).

Also, a number of minimally improved and unimproved areas allow access to other parts of the shoreline. The lake’s large surface area and consistent winds make it one of the best sailing lakes in Oregon.
