Fax | The activities of previous (and existing) mines have demonstrated a "devil may care" attitude as to dust. Example: last summer's coating of fine white dust after a wind storm. |

Email | I have chosen to live in this area because of the excellent air quality. With tailing's and waste piles there will be a lot of dust. We get a lot of wind and this will impact the Tucson basin and surrounding residential areas. I do not want to see the dust in the air and have to breath it. |

Email | Chemical Dust Suppressants or binders- What specific sort of dust suppressants or binders?
Would they be sprayed or mixed into the tailings and would this increse the moisture content if it were mixed? What would be the wind requirements to spray these? We have many windy days here. |

Unique Letter | The dust can cause various skin and respiratory problems. The greatest threat of dust is the prevalence of a fungus that causes Valley Fever in the Southwest, particularly in Arizona. The spores are extremely small, so they can be carried hundreds of miles by the wind. Once inside the lungs, the spores reproduce, perpetuating the cycle of disease. The disease is particularly deadly to the elderly, young, and those with compromised immune systems. In 2007, there were 4,000 cases reported in Arizona, 870 cases in Pima County, principally attributed to the construction industry. I am including two studies of the danger of Valley Fever in disturbed dust, one by the Infectious Diseases Department of Mayo Clinic and one from the U.S. Geological Survey.

Email | We are aware of what the Proposed Rosemont mine will do to control dust by attending all meetings sponsored by the U.S. Forest Service Nepa Scoping process and the internet web site for Rosemont mine. Unfortunately we do not believe this will be enough. DRY STACKING will Problematic for my wife and others who have respiratory problems and disesases, especially who live nearby. Dry stacking is new technology and has never been tried on this large of scale.It has been used a few times in REMOTE and UNPOPULATED areas. This area is neither and the reprecussions will be far reaching. The reduction in water usage will be beneficial, but on the other side of the coin the wind driven dust emissions will be intolerable for people with respiratory problems. |

Email | a) Please provide analysis of air constituents as a function of distance and direction from mining operations and year of operation. Analysis should include all stimulus factors such as dust generation from blasting, shoveling, hauling, dumping, and grading, emissions from power generation and vehicles both onsite and in transit, use of chemical volatiles in the course of operations, effectiveness of dust control techniques, variability of the local climate and winds, and changes in the local micro-climate due to effects created by mining operations such as wind pattern changes created from the pit and waste tailing mounds. Please provide an uncertainty analysis on these predicted effects. |
