Engineering Evaluation and Cost Analysis of Four Former Firing Ranges at Lake Mead NRA

The National Park Service (NPS) retained Environmental Cost Management, Inc. to prepare an Engineering Evaluation/Cost Analysis (EE/CA) Report for Lake Mead National Recreation Area. This EE/CA Report addresses lead impacts at two former firing range sites Clark County, Nevada and two former firing ranges in Mohave County, Arizona. These sites are located at Echo Bay, Las Vegas Bay, Temple Bar, and Willow Beach. The NPS is engaging in a non-time critical removal action process using its authority under the Comprehensive Environmental Response, Compensation, and Liability Act.

The four former firing ranges were used for shooting practice mainly by NPS personnel and local law enforcement officers for several years. For most of them, it is unknown when shooting practice activities began or when they stopped. The EE/CA identifies removal action objectives for protection of human health and the environment, identifies removal action alternatives, and assesses the effectiveness, implementability, and cost of the alternatives that satisfy the removal action objectives. The NPS must secure funding for the removal, after which time a removal design can be prepared and implementation can be scheduled.
