Kalaloch Firing Range Engineering Assessment / Cost Analysis


This Engineering Evaluation/Cost Analysis (EE/CA) has been prepared to address lead contamination at the former Kalaloch Firing Range, located in Olympic National Park (ONP). This EE/CA provides supporting documentation for a non-time critical removal action (NTCRA) at the Kalaloch Firing Range (Site). The EE/CA is being conducted in accordance with Guidance on Conducting Non-Time Critical Removal Actions under CERCLA (EPA, 1993). The EE/CA is a streamlined focused document that provides site characterization data, assesses human health risks, evaluates ecological exposures, evaluates various response alternatives, recommends a preferred response alternative and provides a vehicle for public involvement. This EE/CA was conducted in accordance with the ONP approved EE/CA Work Plan (RMC, 2010a).

The sole threat consists of non-industrial lead impacted soils from use of the Site as a firing range. Two sources of contamination have been identified in the EE/CA: lead in soils; and lead in groundwater.

One Remedial Action Objective (RAO) has been established for the Site: minimize the potential for lead impacts to human health and the environment.
The EE/CA analyzed the following response action alternatives:
Alternative 1 – No Action;
Alternative 2 – Institutional Controls;
Alternative 3 – Removal, On-Site Treatment and Offsite Disposal; and
Alternative 4 – Removal and Offsite Disposal at an Appropriate Disposal Facility.
