• Issues Traffic CAMAS is not requesting an extension to their current hours for hauling out of this site, which are normally 7:00 a.m. to 7:00 p.m.. However,the additional processing hours do equate to CAMAS hauling more product from out of the site. Staff feels the existing acceleration lane and protected left turn lane on U.S. Highway 169 that serve CAMAS' entrance are adequate to handle this additional traffic and are not proposing any changes to the current CUP regarding traffic. Noise Noise is one of the major concerns associated with this request to allow washing, screening, and crushing into the evening hours. This particular mining operation is somewhat isolated. However, where noise will travel can be quite difficult predict. To address the issue of noise, in CAMAS' current CUP the city references state noise level standards and remedies for noise problems, like the placement of stockpile to divert noise. In addition, CAMAS is required to use an alternative to backup alarms outside the hours of 7:00 a.m. and 7:00 p.m., i.e. strobe lights, microwave sensors, cameras, etc.. The sound of backup alarms seems to travel quite far, especially at night. Glare • CAMAS will need to use artificial lighting to work at night. There is language in the CUP regarding standards for lighting and remedies, if it becomes a problem. Water Usage Additional hours for washing gravel means additional water usage. During the drought in the latter part of the 1980s, there were residential wells in this area that were affected by the depletion of the water table. Staff feels condition 18 "Groundwater protection measures", found on page 6 of the attached CUP, adequately addresses this issue. Remedies include curtailing pumping activities until water levels return. Hours of Operation This section contains the ultimate remedy for problems resulting from the additional hours. Proposed language in the attached CUP requires that CAMAS tries to resolve complaints from neighboring residents regarding noise, glare, vibration, dust, or other issues arising from the extended hours. If unresolved by CAMAS,these complaints then go to city staff to see if a resolution can be found. If a satisfactory resolution is not found, the Planning Commission and the City Council shall hold a public hearing to determine if the extended hours should be revoked. The extended hours should only be allowed if they do not unreasonably annoy anyone. Changes to the language in CAMAS' CUP The following are the specific changes to CAMAS' CUP in the order they appear (added language is in bold type and language to be deleted is underlined): f:\shrdoc\b&z\stever\camascup.doc
