The City Council approved the special use permit on May 7, 2007 subject to submittal of annual reports. ATTACHMENTS • Annual Report Hot Mix Asphalt Plant Permit Status Report 2009 In May of 2007 the City of Hastings approved the renewal of a Hot Mix Asphalt Plant Permit through December 2009 with a condition that an Annual Status Report regarding the operation be submitted. The following information is submitted as the Annual Status Report for our Permit dated June 19,1989, and renewed each year since, to operate a hot mix asphalt plant in a sand and gravel mine in the City of Hastings. The operator, Commercial Asphalt Co., is a division of Tiller Corporation. The property is owned by the Metropolitan Council Environmental Services. T .nrati nn The plant site is in a sand and gravel mine located in part in the City of Hastings and in part in Ravenna Township. 'The site is north of Ravenna Trail (CSAH 54) near the intersection with County Road 91. The address is 2445 County Road 54, Hastings, MN. The plant site is in the City of Hastings, near the western entrance to the mine, and south of the Chicago, Milwaukee, St. Paul and Pacific Railroad tracks. A small part of the western portion of the property south of the railroad tracks is within the 100-Year Flood Boundary (flood plain) as set forth on the Flood Insurance Rate Map for the City of Hastings dated December 19, 1981. The plant is at an elevation of 694.2 feet, and therefore not in the flood plain. Operating Hours The current Permit allows operations from 6:00 AM to 5:00 PM, with no hauling before 7:00 AM. However, situations arise such as public emergencies or accelerated work schedules, which may require an extension of our normal operating hours. Whenever there is a request for an extension of our normal operating hours we contact Hastings' city staff. Until granted permission to operate extended hours by City staff we maintain normal operating hours. Estimated Volume The amount of hot mix asphalt produced is dependent on market conditions and demand. We estimate production in 2009 will be approximately 100,000 tons. Traffic Patterns Traffic patterns to and from the plant primarily involve the west entrance to the mine, Ravenna Trail (CSAH 54) and County Highway 91. Traffic moves east and west on Ravenna Trail or north and south on County Road 91. In addition to Ravenna Trail, traffic to and from an area west of the site also uses U.S. Highway 61 for north and south travel through Hastings. Traffic Control Program The safety with which traffic moves to and from our plant and its impact on the health, safety and welfare of the people of the community is a major consideration to us. Safe trucking operations are dependent on the policies and procedures followed, including the condition of the equipment and the attitudes and driving practices of the individual drivers. Our goal is safe and courteous trucking activities to and from our plant to minimize impact on the people around us. We have employed a traffic control program in the interest of safe trucking operations, which includes the following: 1. Access to the plant is limited to the entrance that presently exists. 2. A stop sign is maintained at the exit from the site. 3. Signs have been placed near the plant to encourage safe and courteous driving practices in accordance with all traffic rules and regulations. 4. We follow-up directly with drivers or customers who are not driving safely. Traffic Volumes The quantity of material a truck can haul is dependent on the legal load limit for each specific truck and the weight restrictions on the streets and roads of the intended travel routes. The estimated average load size for trucks hauling material from this plant is 19 tons. Based on the production capacity of the plant, which is approximately 400 tons per hour, and the estimated average load size, the peak number of loads from the plant in any hour during the season will be 21. Air Pollution Control Equipment The plant is equipped with a fabric filter baghouse to control particulate matter emissions (dust). Plant operations require a permit from the Minnesota Pollution Control Agency (MPCA) which specifies performance testing to demonstrate compliance with established standards. This permit also addresses requirements regarding allowable fuels and the control of fugitive emissions (dust from truck traffic) through the application of water. A substantial area of the plant site used by trucks entering and leaving is hard surfaced which greatly reduces dust generated from truck traffic. Petroleum Storage Facilities and Back-up Containment S s The operations of the plant require storage facilities on site for burner fuel, diesel fuel and asphalt cement. These facilities are registered with the MPCA. The tanks have a containment system that will contain the tank contents in case of a spill. The storage facilities and containment are above the 100-year flood elevation. 2 Security Site access is restricted to authorized persons. The site entrance has a gate that is locked during non-operating hours. There is also a series of natural barriers, fences and earthen berms that limit access. Trespassing or infringement by unauthorized persons has not historically been a problem at this site. Status There were no significant changes to the operation during the 2007 production season.
