(A) Conflicts due to noise, dust, or other discharges with regard to those existing and approved uses and associated activities (e.g., houses and schools) that are sensitive to such discharges; We find that land uses on land surrounding the proposed expansion area, and within the impact area, consist of residential, agricultural and industrial uses. Residences are located south, west and north of the proposed expansion area. The nearest residence is located approximately 90 feet north of the boundary of the proposed expansion area. A single agricultural field containing nursery tree stock is located within the impact area, northeast of the proposed expansion area. The existing Delta Sand and Gravel Company facility is located directly east of the proposed expansion area and the Eugene Sand and Gravel facility is located further east across the Willamette River from the Delta Sand and Gravel Company property. The applicant has identified the potential conflicts from the proposed mining of the subject property due to noise, dust and other discharges associated with mining and processing activities in the proposed expansion area. Those conflicts are as follows: Noise The applicant retained Daly-Standlee, Oregon registered engineers, to prepare a noise study for the proposed expansion area. That study, titled “Report On Noise Study for Delta Sand & Gravel New Mining Area”, dated June 14, 2005, is attached to the application. The report concludes that certain areas within the impact area could be subjected to mining activity noise above the limit allowed by the Oregon Department of Environmental Quality (DEQ) for a “new noise source” on a “previously unused site.” Dust and Engine Emissions The applicant retained Bridgewater to prepare an evaluation of air quality issues associated with the proposed expansion area. That evaluation, titled “Air Quality Evaluation”, dated June 1, 2005, is attached to the application. The evaluation concludes that aggregate mining and processing activities could generate dust and potentially create a nuisance condition for the nearby residences due to unusual or annoying amounts of dust present in the ambient air. Other “discharges” under the administrative rule could be defined to include air emissions from diesel engines. However, the Bridgewater evaluation concludes that, due to the small quantity of onsite excavation equipment and haul trucks, and the distant location of the equipment to one another and the proposed expansion area boundary, no conflict due to diesel exhaust will result from mining and processing activities associated with the proposed expansion area. Flooding The applicant retained EGR to prepare an evaluation of flood impacts associated with the proposed expansion area. That evaluation, titled “Evaluation of Potential Flood Impacts: Delta Sand and Gravel Expansion Area”, dated June 6, 2005, is attached to the application. The evaluation concluded that the method of mining the proposed expansion area will not result in a potential to impede flood flow, to reduce flood storage volume within the flood plain or to increase the velocity of water flowing across the site. The report concludes that the method of mining completely avoids any potential adverse flood impacts associated with mining activities on the proposed expansion area and, therefore, that no conflicts associated with flooding will result from mining and processing activities on the proposed expansion area. Groundwater The applicant retained EGR to prepare an evaluation of groundwater impacts associated with the proposed expansion area. That evaluation, titled “Digital Model of Existing Excavation Ordinance - 14
