20.2.66.7 DEFINITIONS: In
addition to the terms defined in 20.2.2 NMAC (Definitions), as used in this
part.
A. “Bale” means a unit of measurement to denote an
amount of lint cotton with a nominal weight of 500 pounds.
B. “Class I area” means any federal land area that is
classified or reclassified as class I as described in 20.2.74.108 NMAC.
C. “Cotton ginning facility” or “facility” means
any facility that separates seed, lint, and trash from raw cotton, and bales
lint cotton for further processing, that will emit no more than fifty (50) tons
per year of any regulated air contaminant for which there is a national ambient
air quality standard, and that has the standard industrial classification code
0724 (cotton ginning) and the North American industrial standard classification
code 115111 (cotton ginning).
D. “Department” is the state of New Mexico
environment department.
E. “Fugitive emissions” means those emissions that
could not reasonably pass through a stack, chimney, vent, or other functionally
equivalent opening.
F. “High efficiency cyclone dust collector” means any
cyclone type collector of the 2D-2D or 1D-3D configuration. These designations refer to the ratio of
cylinder to cone length, where D is the diameter of the cylinder portion. A 2D-2D cyclone would exhibit a cylinder
length of 2 x D and a cone length of 2 x D, with a ninety percent (90%)
efficiency for total suspended particulates. A 1D-3D cyclone would exhibit a
cylinder length of 1 x D and a cone length of 3 x D, with a ninety-five percent
(95%) efficiency for total suspended particulates.
G. “High pressure exhausts” means the exhaust from all
air handling systems located at a cotton gin that are not defined as ‘low
pressure exhausts’.
H. “Low pressure exhausts” means the exhaust from
systems at a cotton gin that handle air from the cotton lint handling system
and battery condenser.
I. “Non-attainment” means designated by the United
States environmental protection agency as not meeting one or more of the
national ambient air quality standards.
J. “Opacity” means the degree to which emissions reduce
the transmission of light and obscure the view of an object in the background.
K. “Owner or operator” is any person who owns or
operates a process or process equipment at the source for which coverage under
the permit has been granted.
L. “20.2.72 NMAC” means the air quality control
regulation 20.2.72 NMAC (Construction Permits); that is, Part 72 of Title 20,
Chapter 2 of the New Mexico administrative code.

20.2.66.200 ISSUANCE OF PERMIT UNDER 20.2.72 NMAC: The
department shall not deny issuance or revision of an air quality construction
permit under 20.2.72 NMAC to any cotton ginning facility, as defined in
Subsection C of 20.2.66.7 NMAC, if the permit application and the permit
conditions meet the requirements of this part.
[20.2.66.200 NMAC -
N, 04/07/05]
20.2.66.201 PERMIT APPLICATION REQUIREMENTS:
Permit applications for each permit issued in accordance with
20.2.66.200 NMAC shall:
A. meet all requirements for the contents of permit
applications under Paragraphs (1) through (3), (5) through (15) of Subsection A
of 20.2.72.203 NMAC and Subsections B through E of 20.2.72.203 NMAC;
B. state that this part is applicable to the cotton
ginning facility;
C. propose maximum allowable annual and hourly emissions
from the facility, and include proposed limitations to hours of operations and
other limitations that will result in allowable emissions of no more than fifty
(50) tons per year of any regulated air contaminant for which there is a
national ambient air quality standard; and
D. include the proposed best system of emissions reduction
for the facility, which for purposes of this part shall include at a minimum
the controls, limitations, plans and practices set out in 20.2.66.202 NMAC.
[20.2.66.201 NMAC -

20.2.66.202 PERMIT REQUIREMENTS:
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
