Draft Engineering Evaluation/Cost Analysis

The National Park Service (NPS) seeks public feedback on a proposal to remove contaminated soils from the former Grapevine shooting range in Death Valley National Park.

The former shooting range is about 0.75 miles east of Grapevine Ranger Station. Park rangers trained and tested with duty firearms at the site. Grapevine shooting range closed in the early 1990s.

The NPS proposes to remove about 77 cubic yards of soil and gravel from the area used as a backstop. This would remove lead and antimony that pose a risk to humans and wildlife.

The Engineering Evaluation/Cost Analysis (EE/CA) Executive Summary highlights key information contained in the EE/CA Report. The Executive Summary (9 pages) contains a summary of the site description, including investigation results and an updated conceptual site exposure model based on these results. A summary of the risk assessment and of applicable or relevant and appropriate requirements also is included along with the scope and objectives of the removal action. It summarizes the the recommended removal action, along with other alternatives considered.
