Officials with the Coronado National Forest are asking for public comment on the Draft Report of the Engineering Evaluation/Cost Analysis for the Mansfield Canyon Watershed Mines: Hosey Mine and Dixie Mine (Site).
These two sites have abandoned mines located on the Nogales Ranger District in Santa Cruz County, southeast of Tucson. Citizens can do their part and provide input on mine waste removal and cleanup.
This report was designed to present a detailed analysis of remediation and clean-up alternatives that can be used for decision making in the future of these locations. The analysis presented in the EE/CA includes discussion of background information, waste characteristics, applicable requirements, a risk assessment, and the development and observation of cleanup alternatives.
The analysis concludes that there are environmental concerns present, including arsenic, lead and antimony. The report outlines a recommended alternative, which is to remove, relocate, and and onsite encapsulation of mine waste/soil.
All public comments are due by the end of the business day on Monday, March 20th, 2017. Following this period, a final decision will be reached and documented in a Removal Action Approval Memorandum, which will identify the alternative selected for site cleanup.
To obtain copies of the EE/CA and Administrative Record, citizens may visit the Coronado National Forest Supervisor’s Office (300 W. Congress Street, Tucson) or the Nogales Ranger District Office (303 Old Tucson Road, Nogales).
To ask questions concerning this comment process, or to review the Administrative Record at the Supervisor’s Office, please contact Gerry Pedrego at (520) 388-8410, or by email at [email protected] Appointments must be made in advance and scheduled during regular office hours.
