Md. Code Regs. 26.11.18.03 - Grain-Drying and Grain-Handling Installations
A. Areas I, II, V, and VI.
(1) A person may not cause or permit the
operation of any grain drying installation unless all exhaust gases discharged
pass through a 24 mesh screen or the installation is fitted with other
equipment or incorporates design features that will accomplish equally
effective results in reducing particulate matter discharge. "Mesh" means Tyler
Standard Screen Scale or its equivalent.
(2) A person may not cause or permit the
operation of any grain drying or handling operation unless the following
procedures are used:
(a) Proper housekeeping
and equipment maintenance procedures, including, but not limited to, prompt
removal of "beeswing" accumulation by a technique which prevents this material
from re-entering the ambient air;
(b) Reasonable precautions to minimize
emissions from grain receiving, conveyance, or load-out facilities in
accordance with good engineering design and operational procedures.
(3) Exceptions.
(a) All grain drying installations in
operation before January 1, 1975, are exempt from the provisions of §A(1) of
this regulation, unless otherwise ordered by the Department after the receipt
of complaints which have been substantiated by Departmental
investigation.
(b) Grain drying
equipment with a total operating capacity of 1,000 bushels (35.2 cubic meters)
per hour or less (manufacturer's rated capacity at 5 percent moisture removal),
located on a farm and more than 200 feet (61 meters) from a habitable dwelling,
is exempt from the provisions of §A(1), of this regulation.
(c) Loading methods dependent upon the design
of an ocean going carrier used as a standard technique at international ports
are exempt from the provisions of §A(1) and (2) of this regulation.
B. Areas III and IV.
(1) A person may not cause or permit the
operation of any grain-drying installation unless all exhaust gases discharged
pass through a 24 mesh screen or the installation is fitted with other
equipment or incorporates design features that will accomplish equally
effective results in reducing particulate matter discharge. "Mesh" means Tyler
Standard Screen Scale or its equivalent.
(2) Exemptions.
(a) All grain-drying installations, except
those in the City of Baltimore, in operation before January 1, 1975, are exempt
from the provisions of §B(1), of this regulation, unless otherwise ordered by
the Department after receipt of complaints which have been substantiated by
Departmental investigation.
(b)
Grain-drying equipment with a total operating capacity of 1,000 bushels per
hour or less (manufacturer's rated capacity at 5 percent moisture removal),
located on a farm and more than 200 feet (60.9 meters) from a habitable
dwelling, is exempt from the provisions of §B(1), of this regulation.
(3) A person may not cause or
permit the operation of any grain-handling installation not located on a farm
without taking reasonable precautions to prevent particulate matter from
becoming airborne. These reasonable precautions shall include:
(a) Proper housekeeping and cleaning
throughout the entire facility, including but not limited to, the prompt
removal of spilled and fugitive "beeswings" and grain-dust accumulation by a
technique which prevents this material from escaping into the
atmosphere.
(b) Covering, at all
times when in motion, open-bodied vehicles transporting dusty material except
for agricultural products in their natural state.
(c) Proper maintenance of all aspiration
systems and dust collection devices.
(d) The use of good engineering design and
operational practices that will minimize emissions from grain receiving,
conveying, processing, mixing, and load-out facilities. For those operations
listed below, located within the City of Baltimore, good engineering design and
operational practices shall include the following:
(i) For grain exporting terminals only, use
of aspiration systems and fabric filter dust collection devices on cleaning,
separating, handling, conveying, and internal transferring equipment unless
specifically exempted by the Department due to the nature, size, throughput, or
location of the equipment.
(ii) Use
of aspiration systems and fabric filter dust collection devices on all truck
and railroad car unloading (dump pit) and load-out areas. All unloading (dump
pit) and load-out areas shall be enclosed in sheds or buildings and utilize
means or devices (including quick-closing doors, air curtains, or wind
deflectors) to minimize the effect of wind currents and drafts. Any alternative
method, technique, or system, which is equally effective in reducing emissions
may be used if approved by the Department.
(iii) Use of a system for the loading of
grain onto a ship or barge which shall include the use of telescoping loading
spouts and automatic level sensing devices. Each spout shall include an
aspiration system exhausting to a fabric filter dust-collection device. While
loading grain, each spout shall be kept at a height no greater than 2 feet (0.6
meter) above the level of the grain surface or at the full extension of the
spout except during topping-off operations or when trimming machines are being
used. The Department may approve the use of alternative control devices,
methods, techniques, work practices, or process changes, provided that
emissions during loading are not greater than 20 percent opacity.
(4) A person may not
cause or permit to be discharged into the outdoor atmosphere from any emission
control equipment installed in accordance with the requirements of §B(3), of
this regulation, particulate matter in excess of 0.03 gr/SCFD (68.7
mg/dscm).
(5) Compliance Schedule.
(a) A person who elects to achieve compliance
with §B(3)(d)(iii), of this regulation, through the use of telescoping loading
spouts, level sensing devices, aspiration systems and fabric filter dust
collection devices, shall adhere to the increments of progress contained in the
following schedule:
(i) By June 1, 1981,
submission of a permit to construct application for the installation necessary
to achieve compliance;
(ii) By
January 1, 1982, beginning of construction of those installations necessary to
achieve compliance;
(iii) By
December 1, 1982, completion of construction and beginning of operations of
those installations necessary to achieve compliance.
(b) A person who elects to achieve compliance
with §B(3)(d)(iii), of this regulation, through the use of approved alternative
techniques shall adhere to the increments of progress contained in the
following schedule:
(i) By July 1, 1979,
submission of a detailed compliance program together with all required permit
to construct applications for the installations necessary to achieve
compliance;
(ii) As expeditiously
as practicable, but not later than July 1, 1980, complete the approved
alternative techniques as described in the compliance program.
