Please Address Comments to: Flagstaff Area National Monuments Attn: Scott Travis, Superintendent 6400 N. Hwy 89 Flagstaff, Arizona 86004 EXPERIENCE YOUR AMERICA Summary The National Park Service (NPS) is planning for a Fire Facility at Sunset Crater Volcano National Monument. This project would be located southeast of the existing visitor center. The purpose of the proposed facility is to improve operational efficiency by consolidating equipment and employee workspaces. As proposed, the facility would consist of approximately 1,850-square-feet of work and storage space. The facility would house and protect two existing NPS fire engines, enabling NPS staff to increase emergency response capabilities. No current facilities exist for this purpose, exposing park resources to the risk of wildland fire danger. The location and size of the facility is based on recommendations made in the Sunset Crater Volcano General Management Plan (2002), fire guidelines recommended in the National Interagency Fire Planning Plan, and a space analysis prepared by an NPS architect working in coordination with park staff. Sunset Crater Volcano National Monument was proclaimed a national monument in 1930. Infrastructure for the monument was constructed during the Mission 66 era in the mid to late 1960s and provides limited work and storage space for fire management activities. The visitor center and surrounding facilities were determined eligible for listing in the National Register of Historic Places through a consensus determination of eligibility between the Arizona State Historic Preservation Office and the National Park Service in February 2004. The limited work and storage space has led to inefficient operations and unsafe work environments for employees. This Environmental Assessment/Assessment of Effect (EA/AEF) analyzes the impacts of two alternatives: 1) no action and 2) construction of the Fire Facility southeast of the visitor center. Impacts to geologic resources, vegetation, wildlife, special status species, archeological resources, historic structures, park operations, and visual quality are described in this document. i Table of Contents Note to Reviewers and Respondents........................................................cover page SUMMARY............................................................................................................................................ i CHAPTER 1.
