Removal of Impacted Soil at Alder Camp Road Firing Range Redwood National Park Attachment 1: Statement of Work

1. Introduction.

1.1. The National Park Service (NPS) has the responsibility under the Comprehensive Environmental Response, Conservation and Liability Act (CERCLA, 42 U.S.C. §§9601 et seq.)

to determine if potential hazardous substances exist within each NPS unit.

1.2. The results of an Engineering Evaluation/Cost Analysis (EE/CA) have identified levels of contaminants in soil that require removal at Alder Camp Road Firing Range at Redwood National Park (REDW).

1.3. The contractor will implement a previously-developed Non Time-Critical Removal Action work plan (NTCRAWP, Attachment 2) to remove contaminated soil and debris, transport it to appropriate disposal facilities, and prepare a Response Action Completion Report. The work includes field and lab analyses of soil samples in addition to preparation of reports and other documentation required for this type of CERCLA action.

1.4. The EE/CA estimates removal of ~1,225 cubic yards or ~1,840 tons of contaminated soil.

1.5. The NTCRAWP is supplemented by this Statement of Work (SOW).

2. Site Information.

2.1. The Alder Camp Road Firing Range area is located in Redwood National and State Parks in Northern California. The Site is entirely within National Park lands. The NPS has had responsibility for the Site since 1968 and the Site had been used as a firing range.

2.1.1. The Site is located approximately 19 miles north of Orick, California off of Highway

101. The Site coordinates are 41°30'40.11"north (latitude) and -124° 4'30.55"west (longitude).

The general location of the Site is shown in the Non-Time Critical Removal Action Work Plan (NTCRA WP) Figure 1, the Site features are shown on Figure 2, and the Site layout is shown on Figure 3. The Site is located in an area of second growth forest. The range is a flat grassy area surrounded by alder, herbaceous plants, sword fern, salmonberry, and other shrubs. The firing range within the Site consisted of a line of 12 targets located at the northern end of the Site.

2.1.2. Access to the Site is via an unimproved, gated road that ties into Alder Camp Road and passes through the Yurok Tribe Reservation and near the Resighini Rancheria. The dirt entrance road is approximately 0.1-mile from Alder Camp Road and terminates at the firing range as shown on Figure 2. The dirt road is closed to the general public and can only be accessed with NPS personnel escort.
