Endpoint Solutions Based upon the onsite availability of some ingredient aggregate materials as well as the proximity to the proposed construction work,the Ramsey Pit Site offers an ideal location for the staging of a portable,temporary RMC plant to be used on the 1-39/90 and supporting municipal projects. Ramsey Pit is requesting this Conditional Use Permit to operate a temporary RMC plant from January 1,2017 to December 31, 2022 for projects awarded on the I-39/90 expansion project. SITING The Site,consisting of Parcel 051206190013 and the portion of Parcel 051206485035 located north of the existing driveway that splits the parcel,currently operates as a quarry on an as needed basis. Ramsey Pit additionally owns four other neighboring parcels,but these parcels will not be involved in any RMC operations as a part of the Conditional Use Permit Application. The proposed RMC plant location was identified based upon the proximity to available material storage areas,accessibility to truck traffic,the presence of a barrier berm and recessed pit area from neighboring parcels,as well as to meet the proper setback requirements as identified in Dane County Zoning Regulations for the Site's A-1EX Exclusive Agricultural district zoning,which are discussed further in the following sections of this letter.No building or structure beyond the mechanical equipment is proposed as part of the application.The batch plant will be portable in order to be located adjacent to where aggregate production is occurring. The proposed area of operation for the portable plant,as well as the existing setback requirements, building footprints, driveways,parking areas,and material storage areas are included in Figure 1. The land use of neighboring parcels along with their zoning is included in Figure 2. OPERATION DESCRIPTION The proposed portable installation of a RMC Plant would be utilized to mix concrete and load trucks for distribution to I-39/90 corridor expansion municipal project jobsites.While the exact number of employees for the plant is currently unknown,similar plants staff between five (5) and fifteen (15) employees as part of a portable RMC plant operation team. Operational periods will include general daytime operating hours of approximately 6:00 AM until 8:00 PM during weekdays and intermittent operation during weekends as project demands arise. However,WDOT does require nighttime work to limit impacts to drivers and to improve worker and driver safety.As such,for some segments of the project this Conditional Use Permit application requests 24-hour operation to accommodate the I-39/90 construction schedule. Outdoor storage would consist of piles stored within the operative area identified in Figure 1, similar to current material staging activities. Cement materials would be stored in portable bins and handled so as to minimize any dust exposure. Activities conducted outdoors at the Site,in addition to the existing mining operations,would include the staging,handling,and mixing of materials,loading of delivery trucks,and washout of trucks into internally drained ponds. Waste generated from washing activities would be handled by removal offsite to an appropriate disposal facility. Domestic waste generation would be handled by an onsite dumpster that is regularly emptied by a local waste management service.
