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:

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.
