DEMOLITION OF STRUCTURE FIRE DEBRIS

AND CONTAMINATED SOILS REMOVAL

I. INTRODUCTION

1. This Statement of Work (SOW) describes a Response Activity for the burned buildings and ash post wildfire at Mojave National Preserve (MOJA), San Bernardino, California. The Contractor shall provide all management, supervision, labor, tools, and equipment necessary to sample, load, haul, accept, process, record, reduce, and dispose of disaster-related debris, ash, underlaying ash, and soil within the burned structures footprint. The debris to be removed varies from site to site and may include vegetation, ash, wood, contaminated soil, remnant structures, remnant concrete/stone/masonry structures, concrete, metal articles, trees that prohibit work performance, stumps, presumed PCB containing light ballasts, chemical containers, steel roofing, plumbing fixtures, railroad ties, etc. Post-removal, the Contractor shall perform soil sampling to identify if residual environmental contaminates above background concentrations remain.

II. LOCATION AND SITE DESCRIPTION

1. The burned buildings located in two areas within Mojave National Preserve (MOJA), California, including Valley View and Kessler Springs. Both burn site locations are located within San Bernadino County, California. These sites are both located off Cima Rd and are approximately 4.8 miles apart. Each site has multiple structures.

2. Valley View Ranch is located on Valley View Ranch Rd off Cima Rd in MOJA. Coordinates are 35.319008, -115.584939. To access site, exit highway I15 onto Cima Rd. Drive ~10.0 miles southeast on paved Cima Rd. Turn right onto Valley View Ranch Rd. Valley View Ranch Rd is a semi-maintained, relatively well-travel one-track dirt road. An all-wheel drive vehicle is recommended. Drive 1.8 miles southwest on dirt Valley View Ranch Rd. to the Valley View Ranch.

3. Kessler Springs Ranch is located off Cima Rd in MOJA. Coordinates are 35.297733, -

115.534763. To access site, exit highway I15 onto Cima Rd. Drive ~13.0 miles southeast on paved Cima Rd. Turn left onto semi-maintained dirt road to Kessler Spring Ranch.

III. BACKGROUND AND EXISTING CONDITIONS

1. Kessler Spring Ranch and Valley View Ranch have been used for ranching activities since the late 1800’s. Kessler Spring Ranch is a ranch with a septic pit, corrals, water well/supply systems, spring box/concrete drinker and two stockpiles of burned rubble and debris. The ranch house at Kessler Spring Ranch was registered as a historic park structure. Valley View Ranch is a ranch with a main ranch house, corrals, generator, solar array, and burned rubble and debris. Both ranches are contributing to the Rock Springs Land and Cattle Company cultural landscape, which is listed on the National Register of Historic Places.

2. On August 15, 2020, a lightning strike resulted in a 43,273-acre wildfire that burned through the Joshua Tree woodland of Cima Dome (referred to since as the “Dome Fire”). As a result, many of the structures on Kessler Spring Ranch and Valley View Ranch were reduced to burned building debris, including masonry/concrete walls and foundations, charred timbers, tin metal siding, floor tile, stucco, and ash.

3. The NPS will provide:

A. Site Evaluation Report, Dome Fire Time Critical Removal Action, Mojave National Preserve, San Bernardino County, CA, August 2021.

• The Site Evaluation Report, prepared by Professional Environmental Engineers, Inc., tested site debris and soils for asbestos and the results were all negative. Debris samples were selected based on materials that were identified as suspect asbestos-containing materials as documented in field notes. Contractor shall perform due diligence on reviewing these materials.
