The Tahoe National Forest is requesting public comment on an Engineering Evaluation/Cost Analysis for the Relief Hill Diggings Hydraulic Mine. Tahoe national Forest Information Officer, Michael Woodbridge, says all public comments are welcome and will be accepted until the close of business January 12th.
The purpose of the EE/CA is to present a detailed analysis of cleanup/removal action alternatives that can be used for decision-making.
Surface water runoff from the site flows into Logan Canyon which drains into the South Yuba River.
The Relief Hill EE/CA describes the conditions at the site and threat to human health, as well as presents a detailed analysis of removal action alternatives.
Woodbridge say there are three preliminary Removal Action objectives for Relief Hill Diggings:
Attaining these objectives is expected to result in protection of human and ecological receptors and water quality in the South Yuba River watershed.
For more information contact Rick Weaver at the TNF Office.
Four removal action alternatives are proposed and evaluated for Relief Hill Diggings. The recommended removal action alternative includes:
- engineering controls to reduce erosion and sediment yield,
- land use controls to reduce erosion caused by mechanized equipment and off-highway vehicle traffic
- establish the growth of soil-stabilizing vegetation and
- reduce direct human contact with contaminants.
Following this 30-day public comment period, a final decision will be made by the Pacific Southwest Region’s Regional Forester, and the decision will be documented in a Removal Action Memorandum identifying the removal action decision.
