UPDATE: Deadline for public comments extended on abandoned mines in Santa Cruz County

SANTA CRUZ COUNTY, AZ (Tucson News Now) -

Officials with the Coronado National Forest are requesting public comment on the Draft Report of the Engineering Evaluation/Cost Analysis for the Mansfield Canyon Watershed Mines: Hosey Mine and Dixie Mine (Site), two abandoned mines located on the Nogales Ranger District, Santa Cruz County, Nogales, AZ.  

UPDATE: public comment period has been extended until May 20, 2017.

The purpose of the EE/CA report is to present a detailed analysis of remediation (clean-up) alternatives that can be used for decision making.  In addition, the analysis presented in this EE/CA includes discussion of background information, waste characteristics, applicable or relevant and appropriate requirements, a risk assessment, and the development and screening of cleanup alternatives.

The EE/CA concludes that the site has environmental concerns related to arsenic, lead, and antimony.  The recommended alternative for the site is to remove, relocate, and onsite encapsulation of mine waste/soil. Two mines require further investigation due to releases of contaminated water from the openings.

Following this comment period, a final decision will be made and the decision will be documented in a Removal Action Approval Memorandum identifying the alternative selected for the cleanup of the site.

Copies of the EE/CA and Administrative Record are available at the Coronado National Forest Supervisor’s Office (300 W. Congress Street, Tucson) and the Nogales Ranger District Office (303 Old Tucson Road, Nogales).

To ask questions concerning this process, or to review the Administrative Record at the Supervisor’s Office, please contact Gerry Pedrego at (520) 388-8410, or by email at gpedrego@fs.fed.us Appointments must be made in advance and scheduled during regular office hours.

Comments may be mailed or hand delivered (weekdays, 8 a.m. – 4:30 p.m.):
