Sky Brightness and Light at Night: Santa Rita Mountains, Arizona 1. Airborne and Ground-based Reference Data Collection. Craine et. al. (survey data for Rosemont Mine project)
The goal of this survey was to obtain ground and airborne measurements of sky brightness in a specified 250 square mile area, roughly centered on the Santa Rita Mountain Range of southern Arizona. These measurements are intended to serve as an epoch October – November, 2011 baseline of sky brightness and local light at night (LAN).
Rosemont Copper Project Light Pollution Mitigation Recommendation Report, Christian K. Monrad, James Benya, and Dr. David L. Crawford.
Neither the existing 2006 Pima County Outdoor Lighting Code (PCOLC) nor the draft
2011 PCOLC have jurisdiction over the Project site for the development as proposed.
However, as part of its commitment to best possible environmental practices, Rosemont
Copper Company (Rosemont) will voluntarily employ an advanced light pollution
mitigation plan. The plan will include the use of state of the art lighting equipment and
controls to minimize environmental impact to levels below the intent of the PCOLC,
including other comparable modern light pollution control standards. Importantly, the
plan must also comply with the project’s operational safety requirements prescribed by
the Mine Safety and Health Administration (MSHA).
