Wire gabion baskets were installed downstream of the main adit. Waste rock was placed in a consolidation cell and capped. This included waters tinted white, yellow, orange and red flowing from the Lead Queen Mine adit, indicating release and oxidation of mineralized waters and sediment.Īn environmental cleanup was completed in February, 2016 to reduce or eliminate downstream movement of waste rock containing elevated concentrations of arsenic, lead, and other heavy metals, and to prevent acid mine drainage from entering into Harshaw Creek.Īdits and shafts were closed with polyurethane foam or bat-friendly metal gates. The Coronado National Forest is designing a system to augment environmental cleanup work previously performed at the Lead Queen Mine on the Sierra Vista Ranger District.Īn unusually wet summer monsoon season in 2014 contributed to colored runoff in some drainages in the Patagonia Mountains. Repairs to be Performed on Lead Queen Mine Closure The agency is obligated to consider this material when drafting the EA or EIS.Īct Now: Hermosa-Taylor Deposit Drilling Project Scoping Notice and Plan of Operation.ġ National Environmental Policy Act (NEPA), 42 USC § 4332(C) (1982).Ģ Council for Environmental Quality, NEPA Implementing Regulations, 40 CFR § 1508.8 (2010). You should also submit any research or supporting documentation that is relevant to assessing the significance of the project’s potential impacts. At the scoping stage, you just need to identify the issues and potential impacts that must be analyzed. REMEMBER: You don’t have to do the analysis for the agency. Cumulative impacts can result from individually minor but collectively significant actions taking place over a period of time.” ² Cumulative impacts: “the impact on the environment which results from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions, regardless of what agency or person undertakes such actions.Indirect impacts: “are caused by the action and are later in time or farther removed in distance, but are still reasonably foreseeable (e.g., induced changes in land use patterns, population density, and related effects on natural resources and ecosystems) ” and.Direct impacts: “are caused by the action and occur at the same time and place ”.When assessing potential impacts, the agency must look at: The potential impacts will vary depending on the specific activity being proposed, and can include ecological, aesthetic, historic, cultural, economic, social, and health related impacts. The scoping period is also the best time to identify all the potential impacts that are likely to result from the proposed action. Identify potential impacts resulting from proposed action. Watersheds Floodplains, wetlands, and riparian areas. ![]() ![]() Wildlife and vegetation, including endangered, threatened, and other special status species.This includes all the resources and values that are likely to be impacted by the proposed action, including: Identify resources likely to be impacted. The scoping period is the best time to identify all the issues and resources that the agency must consider when preparing an EA or EIS, as well as the potential impacts the proposed action may have on those resources. Scoping also helps the agency determine the likely significance of an action’s impacts, and whether an EA or an EIS will be required. Environmental Impact Statement ( EIS), a detailed and thorough analysis used for those actions that are expected to result in significant impacts.įederal agencies are required to go through a public “scoping process” in order to determine the scope of issues that should be addressed in an EA or EIS.Environmental Assessment ( EA), a brief analysis used to determine the significance of impacts resulting from a federal action, or.The National Environmental Policy Act (NEPA) requires all federal agencies to prepare a “detailed statement” on the impacts of any proposed action that may “significantly affect the quality of the human environment.”¹ This “detailed statement” can take one of two forms: Introduction: National Environmental Policy Act & Scoping Process Writing NEPA Scoping Comments: EA or EIS projects ![]()
