Hot Mix Asphalt Plant Permit
Status Report 2008
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.
Location
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.
During 2007 there were three requests for extended hours of operation. One of the
requests was for MN / DOT's Highway 95 project in southern Washington County and the
other two were for City of Hastings street projects. Hastings' city staff reviewed all four
requests and granted permission to operate extended hours.
Estimated Volume
The amount of hot mix asphalt produced is dependent on market conditions and demand.
We estimate production in 2008 will be approximately 150,000 tons.
Traffic Patterns
Traffic patterns to and from the plant primarily involve the west enh'ance 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 System
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.

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 barriersl 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.
