Any new aerospace equipment and parts manufacturing plant, or physical
and operational change to an existing aerospace equipment and parts manufacturing
plant are permitted by rule, provided that the following conditions of this
section are satisfied.
(1) For purposes of this section, aerospace equipment and parts
manufacturing plant means the entire operation on the property which engages
in the fabrication or assembly of parts, tools, or completed components of
any aircraft, helicopter, dirigible, balloon, missile, drone, rocket, or space
vehicle. This permit by rule will not include composite aerospace equipment
and parts manufacturing plants. Composite plants are defined to be plants
whose products are less than 50% metal, by weight, based on annual production
figures. This definition excludes those operations specifically authorized
by other permits by rule. For example, a boiler would not be considered a
part of the aerospace manufacturing plant, but could be authorized under §106.181
of this title (relating to Small Boilers, Heaters, and Other Combustion Devices),
if all pertinent requirements were met.
(2) Emission points associated with the aerospace equipment
and parts manufacturing plant or changes to that plant shall be located at
least 100 feet from any off-plant receptor. Off-plant receptor means any recreational
area or residence or other structure not occupied or used solely by the owner
or operator of the aerospace equipment and parts manufacturing plant or the
owner of the property upon which the aerospace plant is located. Controlled
access recreational areas owned by the property owner or the owner or operator
of the aerospace plant are not off-plant receptors.
(3) The total annual emissions, in tons per year, of the
following air contaminants authorized under this section, on a cumulative
basis, from the entire aerospace manufacturing plant shall not exceed the
values specified:
(A) inhalable particulate matter--five tons per year (tpy);
(B) volatile organic compounds (VOC)--15 tpy;
(C) acid gases or vapors--five tpy;
(D) non-VOC carbon compound emissions--ten tpy;
(E) total of air contaminants in subparagraphs (A) - (D) of
this paragraph--25 tpy.
(4) Hourly emissions of total new or increased emissions,
including fugitives, of particulate matter or chemicals listed or referenced
in Table 262 of §106.262 of this title (relating to Facilities (Emission
Distance Limitations)), shall not exceed the hourly emission rate, E, as determined
using the equation, E = L/K lb/hr and Table 224A, where:

(5) Before construction or change in operation begins,
registration shall be submitted to the commission's Office of Permitting,
Remediation, and Registration in Austin using a completed Form PI-7. The emission
data provided in the PI-7 shall include all process emission sources at the
plant, both existing and proposed, and shall be the maximum allowed emissions
for permitted units, the actual emissions for existing grandfathered units
or units permitted by rule, and the projected maximum allowable emissions
for proposed units. Emissions shall be speciated by chemical compound and
the stack parameters, as appropriate, for each emission source shall be provided.
Registration shall include a description of the project, calculations, and
data identifying specific chemical names, "L" values, "D" values, and a description
of pollution control equipment, if any.
(6) An emissions inventory shall be compiled and/or updated
on an annual basis for all process emission sources on the property, maintained
on a two-year rolling retention cycle, and made available upon request by
the executive director. The inventory records should include the basis for
all emissions estimates, sample calculations, and material usage records.
Material and solvent usage records shall be maintained in sufficient detail
to document compliance with this section.
(7) There shall be no visible emissions from each existing
and proposed stack, hood, vent, or opening to the atmosphere.
(8) Any facility in which any chemical listed in subparagraph
(D) of this paragraph will be handled or stored as a liquid or a compressed
gas in a compound mixture of a concentration greater than 10% by weight or
an aqueous solution of any chemical listed in subparagraph (D) of this paragraph
greater than 50% by weight shall comply with subparagraphs (A) - (C) of this
paragraph.
(A) The facility shall be located at least 300 feet from the
nearest property line and 600 feet from any off-plant receptor.
(B) The cumulative amount of any one of the chemicals listed
in subparagraph (D) of this paragraph, resulting from one or more authorizations
under this section, shall not exceed 500 pounds on the plant property.
(C) Any chemical listed in subparagraph (D) of this paragraph
shall be handled only in containers operated in compliance with United States
Department of Transportation regulations (49 Code of Federal Regulations,
Parts 171-178).
(D) Listed chemicals are: acrolein, ammonia, bromine, carbon
disulfide, chlorine, ethyl mercaptan, hydrogen chloride, hydrogen bromide,
hydrogen cyanide, hydrogen fluoride, hydrogen sulfide, phosphine, sulfur dioxide,
methyl bromide, methyl isocyanate, methyl mercaptan, nickel carbonyl, phosgene.
