These regulations apply to permanent concrete plants and concrete and asphalt crushing operations, they do not apply to temporary portable batch plants and crushing operations related to a specific construction project.
(a) Concrete / Asphalt Plants:
(1) Must have a minimum lot area of three acres.
(2) To reduce the effects of airborne dust, dirt, and noise, plant equipment, stockpiles, truck staging areas, and similar operations must be located no closer than 300-feet to any road right-of-way line, no closer than 100-feet to any adjacent property lines, and no closer than 500-feet to any residentially zoned property.
(3) All driveways, loading areas, staging areas, and truck maneuvering areas within the site must be paved.
(4) The outside storage of materials other than sand, gravel, and other natural materials used in the concrete manufacturing process is prohibited. The location and size of sand and gravel storage areas must be shown on the site plan; stockpiles cannot exceed twenty-feet in height, or as otherwise approved by the Planning Commission.
(5) Plant facilities, including parking and loading zones and stockpiles, must be screened.
(6) The proposed recovery system for excess concrete must be noted on the site plan; storage of excess concrete on the site cannot exceed the limits specified in the approved recovery plan.
(b) Concrete / Asphalt Crushing Facilities:
(1) Operations must be setback a minimum of 500-feet from any parcel occupied by a residential or public use.
(2) All rubble must be processed (mechanically and/or manually) to separate extraneous material, such as metal and plastic, before the concrete or asphalt is crushed. The extraneous material must be removed to a properly zoned disposal area for recycling.
(3) Material to be crushed or in the process of being crushed must be watered to minimize the dust generated by the operation when seasonal conditions permit. Interior haul routes and faces of rubble piles must also be watered periodically for the purposes of dust control.
(4) Operations must be screened from abutting residentially zoned property.
(5) Hours of operation are limited between 7:00 a.m. and 7:00 p.m., Monday through Friday, and between 8:00 a.m. and 5:00 p.m. on Saturday. Crushing operations are prohibited on Sundays and legal holidays.
