Current through Vol. 24-12, July 15, 2024
Rule 289.
(1) This
				rule does not apply if prohibited by
				R
				336.1278 and unless the requirements of
				R
				336.1278a have been met.
(2) The requirement of
				R
				336.1201(1) to obtain a permit to
				install does not apply to any of the following:
(a) A cold feed aggregate bin for asphalt and
				concrete production equipment.
(b)
				A liquid asphalt storage tank that is controlled by an appropriately designed
				and operated vapor condensation and recovery system or an equivalent control
				system.
(c) An asphalt concrete
				storage silo that has all its emissions vented back into the burning zone of
				the kiln or that has an equivalent control system.
(d) A concrete batch plant that meets all of
				the following requirements:
(i) The plant
				shall produce not more than 200,000 cubic yards per year.
(ii) The plant shall use a fabric filter dust
				collector, a slurry mixer system, a drop chute, a mixer flap gate, or an
				enclosure for truck loading operations.
(iii) All cement handling operations, such as
				silo loading and cement weighing hoppers, shall either be enclosed by a
				building or equipped with a fabric filter dust control.
(iv) The owner or operator shall keep monthly
				records of the cubic yards of concrete produced.
(v) Before commencing operations, the owner
				or operator shall notify the appropriate district supervisor of the location
				where the concrete batch plant will be operating under this
				exemption.
(vi) The concrete batch
				plant shall be located not less than 250 feet from any residential or
				commercial establishment or place of public assembly unless all of the cement
				handling operations, excluding the cement silo storage and loading operations,
				are enclosed within at least a 3-sided structure.
(vii) The owner or operator shall implement
				the following fugitive dust plan:
(A) The
				drop distance at each transfer point shall be reduced to the minimum the
				equipment can achieve.
(B) On-site
				vehicles shall be loaded to prevent their contents from dropping, leaking,
				blowing, or otherwise escaping. This shall be accomplished by loading so that
				no part of the load shall come in contact within 6 inches of the top of any
				sideboard, side panel, or tailgate. Otherwise, the truck shall be
				tarped.
(C) All of the following
				provisions apply for site roadways and the plant yard:
(1) The dust on the site roadways and the
				plant yard shall be controlled by applications of water, calcium chloride, or
				other acceptable and approved fugitive dust control compounds. Applications of
				dust suppressants shall be done as often as necessary to meet an opacity limit
				of 5%.
(2) All paved roadways and
				plant yards shall be swept as needed between applications.
(3) Any material spillage on roads shall be
				cleaned up immediately.
(4) A
				record of all applications of dust suppressants and roadway and plant yard
				sweepings shall be kept for the most recent 5-year period and be made available
				to the department upon request.
(D) All of the following provisions apply for
				storage piles:
(1) Stockpiling of all
				nonmetallic minerals shall be performed to minimize drop distance and control
				potential dust problems.
(2)
				Stockpiles shall be watered on an as-needed basis in order to meet an opacity
				limit of 5%. Equipment to apply water or dust suppressant shall be available at
				the site or on call for use at the site within a given operating day.
(3) A record of all watering shall be kept on
				file for the most recent 5-year period and be made available to the department
				upon request.
(E) The
				provisions and procedures of this fugitive dust plan are subject to adjustment
				by written notification from the department if, following an inspection, the
				department determines the fugitive dust requirements or permitted opacity
				limits are not being met.
