Current through Register Vol. 35, No. 18, September 24, 2024
Permits issued in accordance with
20.2.66.200
NMAC shall include the following best system of emissions reduction, as well as
other conditions, including but not limited to recordkeeping, monitoring,
reporting requirements, and test methods, as required to ensure the
enforceability of permit conditions.
A. Limitations from application: except as
modified by the department, the proposed emission reduction system and
limitations specified in the application.
B. Emissions control on high pressure
exhausts.
(1) All emissions from high pressure
exhausts shall be controlled by the use of a high efficiency cyclone dust
collectors (the terms high pressure exhaust and high efficiency cyclone dust
collectors are defined in 20.2.66.7 NMAC).
(2) The opacity of visible emissions from
cyclones shall not exceed twenty percent (20%).
C. Emissions control on low pressure
exhausts.
(1) All emissions from low pressure
exhausts (as defined in Subsection H of 20.2.66.7 NMAC) shall be controlled by
the use of screens with a mesh size of 70 by 70 or finer (United States sieve),
or the use of perforated condenser drums with holes not exceeding 0.045 inches
in diameter, or with equipment of equivalent or higher design efficiency, as
determined by the department.
(2)
The opacity of visible emissions from low pressure exhausts shall not exceed
twenty percent (20%).
D.
A fugitive dust management plan that includes the following, or methods at
least as effective in controlling fugitive dust.
(1) Complete enclosure of all burr
hoppers.
(2) Measures to be taken
to control fugitive dust emissions from any source, process or operation
occurring within the cotton gin building to assure that no fugitive dust
emissions to the outside atmosphere from any door, vent, or window are
visible.
(3) Measures to be taken
to minimize fugitive emissions from the handling, transportation or disposition
of any substance or material that is likely to be scattered by the air or wind
at the facility, including but not limited to materials in the gin yard and
haul roads, including all open areas, right-of ways, storage piles, and
vehicles at the facility. Such measures shall be sufficient to assure that no
visible fugitive dust emissions generated from the property leave the property.
Emissions may be controlled by watering, paving and cleaning, surfactants, or
other equivalent means.
(4) The
posted speed limit for all vehicles on unpaved haul roads and in unpaved yard
areas shall be no more than 10 miles per hour.
E. Requirements for fuel burning equipment.
This subsection applies to fuel burning equipment such as driers and
humidifiers, but does not apply to mobile sources (such as loaders, haul
trucks, and other vehicles).
(1) Any
emissions from fuel burning equipment shall not exhibit greater than 20 percent
opacity.
(2) The owner or operator
shall use only the following fuels: natural gas, liquefied petroleum gas (LPG),
propane, or No. 2 diesel fuel with a sulfur content equal to or less than 0.05
percent by weight.
(3) The owner or
operator shall operate and maintain the equipment such that emissions and
opacity limitations in the permit are met.
F. Location restrictions.
(1) The distance from the cotton gin to the
property boundary shall be at least ten (10) feet in all directions, or the
distance established in Paragraph (2) of Subsection F of 20.2.66.202 NMAC,
whichever is greater.
(2) The
minimum distance (in feet) in all directions from the cotton gin to the
property boundary shall be calculated as the multiple of the square of the
maximum emission rate (in pounds of PM10 per hour) and 0.2385, plus the
multiple of the maximum emission rate (in pounds of PM10 per hour) and 54.0718,
minus the value 816.0886.
(3) The
distance from the cotton gin to the nearest existing state park, recreation
area, or school shall be at least 0.25 miles. The distance from the cotton gin
to the nearest class I area shall be at least three miles.
G. Maintenance of equipment.
(1) All materials handling systems and
control equipment shall be installed and operated as required to assure that
permit conditions will be met.
(2)
The owner or operator shall conduct daily visual inspection of the material
handling systems for leaks, breaks or other visible signs of equipment
malfunctions, and repair such leaks, breaks or malfunctions in a timely
manner.
(3) The owner or operator
shall maintain a record of the daily inspections, including any equipment
malfunctions discovered and corrective action taken to repair the
malfunction.
