2. LOCATION and SITE DESCRIPTION

2.1. The twenty-two burn sites addressed by this activity are located within Rocky Mountain National Park (ROMO) in north-central Colorado, approximately 55 miles northwest of Denver. The park is situated between the gateway communities of Estes Park to the east and Grand Lake to the west.

Location maps for the Sites are provided in Attachment 5. Information regarding ROMO is available at Rocky Mountain National Park (U.S. National Park Service) (nps.gov).

2.1.1. Lodging and meal services are available at both gateway communities and other nearby communities including Granby and others within 50 miles of the Sites.

2.1.2. Establishment of a construction camp will not be permitted, although use of public campgrounds is allowed.

2.2. Nineteen (19) Sites are located on the west side of the park in the Colorado River District (CRD) between approximately three (3) and seven (7) road miles from Granby. Eighteen Sites in the CRD are located in the Green Mountain / Onahu Ranch geographic area and are directly accessible by paved or dirt roads.

2.2.1. The Betty Dick Garage Site (Site ID 831) is located at the Betty Dick Ranch geographic area.

Access to this Site crosses the Colorado River via a structurally deficient bridge approximately 65 feet long. No vehicular traffic is allowed over the bridge. Contractor personnel can access the Site via the bridge on foot from a parking area located approximately 0.3 miles from the Site. Aviation will be required to import and remove construction equipment and materials and to remove wastes to a staging area for loading and transport for disposal via sling load. See Aviation Requirements in Section 9.9.

2.3. Three (3) Sites are located on the east side of the park in two geographic areas.

2.3.1. Two Sites, Moraine Park Stables Mess Hall (Site ID 893) and Moraine Park Stables Residence (Site ID 1086), are located approximately seven (7) paved road miles from Estes Park.

2.3.2. The Fern Lake Ranger Station (Site ID 14) is located in designated Wilderness Area and can only be accessed by contractor personnel via approximately 4-mile hiking trail. The site is located at approximately 9500 feet above sea level. Aviation will be required to import and remove construction https://www.nps.gov/romo/index.htm equipment and materials and to remove wastes to a staging area for loading and transport for disposal via sling load. See Aviation Requirements in Section 9.9.

2.3.3. The Sites are located at elevations ranging between approximately 8,000 and 9,500 feet above sea level, with summertime temperatures ranging from the 40’s at night into the 70’s or 80’s during the day.

2.3.4. The Sites are normally accessible from approximately May through October, although the Fern Lake Ranger Station will likely have a more limited construction season due to elevation.

2.3.5. The east and west sides of the park are seasonally connected by Trail Ridge Road (generally closed from around October through May), but contractors are advised this road is not suitable for construction traffic and may not be reliable for daily worker commuting.

2.3.6. The Sites, except as noted above, are accessible by paved or dirt roads. All Sites or aviation staging areas connect to major highway systems via paved mountain roadways.

4.12. Option C – Perform Baseline Ecological Risk Assessment (BERA) to Evaluate Initial Site Characterization and/or Confirmation Sampling Results and Establish Remedial Goals

4.12.1. If refined screening level risks are determined to be unacceptable, the ecological risk assessment may continue and a Baseline Ecological Risk Assessment (BERA) may be performed, which includes a refinement of steps 1 and 2, and Steps 3 through 7 of the ecological risk assessment process as described by EPA (1997). The BERA shall include the following:

• The refinement of the site-specific CSEM for ecological exposure, if needed.

• The specification of management goals, assessment endpoints, and measures of effect as described in EPA Guidelines for Ecological Risk Assessment (EPA 1998; EPA/630/R-95/002F).

• The calculation of HQs for a range of appropriate ecological receptor populations using site-specific exposure assumptions, appropriate toxicity values, and 95UCL or the exposure point concentrations. For plants and invertebrates, this will include use of no-effect and low-effect toxicity values from, for example, the ECORISK database developed by the Los Alamos

National Laboratory (LANL) (https://www.lanl.gov/environment/protection/eco-risk-assessment.php). For wildlife, this will include the comparison of dose-based estimates of exposure using food chain modeling for a range of surrogate receptors to no-effect and low-effect toxicity values from the literature.

• As appropriate, additional lines of evidence, such as site-specific toxicity tests, population evaluations, relevant uncertainties in the ecological toxicity literature, and home ranges versus nesting areas, may be employed to support final risk conclusions and identification of contaminants of ecological concern (COECs) as part of a weight of evidence evaluation.

• If ecological risks are determined to be unacceptable, estimate risk based PRGs for each COEC and each terrestrial receptor type (avian, invertebrates, mammals, and plants) based on the available lines of evidence. When computing PRGs based on an HQ approach, estimate risk-based PRGs based on a target HQ of 1 and a threshold-based effect level (e.g., the geomean of a no effect and low effect value). Compare those PRGs to site-specific background concentrations for consideration in recommending final RGs.

4.12.2. Four other burn sites within the CRD but not included in this removal action, as described in Section 4.10.2, shall be included in the risk assessment, as directed by NPS.

4.12.3. The Contractor shall prepare draft, draft final, and final BERA Reports.

4.12.3.1. Submit the draft BERA Report to the Contracting Officer or designee within 60 days of the Contracting Officer exercising the Option C.

4.12.3.2. NPS will provide comments within 30 days after receipt of draft BERA Report.

4.12.3.3. Submit the draft final BERA Report incorporating NPS comments to the Contracting Officer or designee within 10 days of receiving comments from the NPS.

4.12.3.4. NPS will provide comments within 15 days after receipt of draft final BERA Report.

4.12.4. Submit the final BERA Report incorporating NPS comments within 10 days of receiving comments from NPS.
