Lighting Technical Memorandum TITLE: Rosemont Mine Outdoor Lighting & Pima County Outdoor Lighting Code RELEASE DATE: May 2009 PREPARED BY: M3 Engineering & Technology Inc. Brief Summary: The 2006 Pima County Outdoor Lighting Code regulates the amount of light permitted outdoors within the City of Tucson and Pima County. The Rosemont mine is within an area of Pima County that is the most restrictive lighting area of the code. While the mine is exempt from complying with the lighting code, Rosemont Copper plans to operate within the intent of that code as long as mine safety and operations are not compromised. The specific type of light sources recommended for each area of the Rosemont mine is dependent upon the work station activity; pedestrian, vehicle and equipment traffic; and potential for hazards. Rosemont Copper is working with heavy equipment manufacturers and lighting manufacturers to identify light sources and shielding methods to further limit any light pollution.
The lighting study looked at the need for lights that will limit light pollution and comply with strict Pima County lighting codes. rosemont copper
