Proposed Conditional Use Permit#2338 (page 3) 5/10 ZLR: The petition was postponed due to public opposition. The neighborhood expresses concerns regarding the dust, lack of trees on the berm, noise generation, possibility of well contamination, the size of the active area, additional buffering for residences, and the time limit of the conditional use permit. Statff Update: County Staff has reviewed the concerns and have the following comments: Dust Dust reduction is addressed under condtion#16. The operator is required to use spray bars in the crushing operation and on the drive path as needed. The operator has also extend the paved driveway an additional 300 feet to reduce the dust. Berms During the approval of the quarry in 2001, the Committee discussed the berms. It was decided not to place evergreens on top of the berm. The current condition of the berms are fully vegetated and appears to match the roadside in the area. Noise There is no blasting permitted on the site. The hours of operation are limited to 6am to 6pm, Monday through Friday, with limited hours on Saturday. See condition#12. Berms have been installed to m itigate noise. Trucks are prohibited on using jake brakes in the vicinity of the quarry. Well Contamination Vierbicher Associates conducted a hydrological study regarding the quarry operation in 2001. Due to bulk fuel storage being prohibited on the site, there is a very low risk of groundwater contamination from the quarry activity. In 2005, wells in the area were tested and found no contamination. The primary concern for groundwater contamination for the area will stem from the abandoned landfill that is located north of the quarry. Open Area of production Yahara Materials has suggested that 30 acres may be exposed. As the quarry operation continues, most of the area will be occupied by suface water due to the lowest point of the deposit being just below the water table. Buffers The property is bordered by Highway 78 on the east and the railroad and agricultural field to the west. The site is required to have a 10-foot tall berm surrounding the open excavated area. The reclamation plan shows that the quarry operation will be no closer that 350 feet to the nearest resident at the final stages of the operation. Staff feels that adequate measures area in place to minimize the impacts to neighboring residences. CUP timeframe The quarry site has been in operation without complaint for the past 15 years. The Town of Mazomanie has approved the condtional use permit for another 15 years. Staff does not see any issues with the 15-year time frame.
