modeling for the proposal. He said without air dispersion modeling the commissions had no basis to make a decision on: . 1. Whether the proposed expansion would cause significant air pollution and dust fallout impacts, 2. Whether the project would or could be mitigated to minimize potential impacts, and 3. The degree and downwind distance that potential significant impacts would occur which was important to determine'the proper impact area for the PAP A administrative rule analysis. Mr. Stotter said there was no assurance to the public that there were not significant pollution impacts. He added that Ms. Sears was a specialist in air pollution impacts and dismissed the testimony of Dick Ruth because he had not listed his degree as part of his qualifications. He said Ms. "Sears had determined that there were serious and significant air pollution impacts to farms and residents near the site. Dr. Stephen Kimberly, 85296 Ridgetop, spoke 4t opposition to the application. He said he was a board certified specialist in internal medicine and had also been past president of the Alliance for Lung Cancer. He said he had extensive trainingin lung and pulmonary diseases. He said he could not speak to the amount of dust that would be created by the proposed expansion. He remarked that there had already been testimony to that topic and speculated that the amount of dust created would be significant. He said there would definitely be health effects from the dust of the quarry. He said miners who were exposed to coal dust had a much highe~ incidence of lung disease. He said his concern was that rock dust varied in size ranged from 2-10 microns and remarked that particulate matter in that size range would increase the episodes of bronchitis, asthma attacks and chronic obstructed pulmonary disease. He said COPD was a leading cause of death in the United States and was increasing dramatically. He said one of the leading causes of COPD was chronic bronchitis. He said, over time, the lungs would lose elasticity and fibrotic tissl:1e would form in the lungs and COPD would oCcur. He added that rock dust was chemically reactive and said there would be reaction in lung tissue that, in addition to causing more fiberous tiss~e, might lead to lung cancer. He said children that were exposed to rock dust would be found to have slowly developing lungs and would be more susceptible to bronchitis. In response to a question from Lane County Planning ~ommissioner Nancy Nichols regarding whether some of the particulate would fallout of the air, Dr. Kimberly said those who were working to mine the rock would be the most exposed to particulate but remarked that, given the statements made by Camile Sears about residents being exposed to wind born dust 50 percent of the year, the dust would be by no means innocuous. In response to a question from Ms.. Arkin regarding his assessment of the additional particulate matter added to the pollution in the area, Dr. Kimberly said it would increase health risks in terms of the lungs for a significant portion of the community. He said it had been 'estimated that every ten years of exposure to dust doubled the chance of lung disease from particulate matter. He acknowledged that he was not an expert in rock processing but speculated that the activities at Delta would produce 1 million tons of rock per year and that a ton or more of particulate matter would be dispersed into the air. Mr. Dignam commented that a farmer living nearby the site had testified at the previous hearing that he generated significantly more dust than was, generated by Delta Sand and"Gravel. He add-ed that he lived on. a gravel driveway shared by five families. He questioned how the dust generated by Delta was different from other dust generated in Lane County.
