Body repair and refinishing of motorcycle, passenger car, van, light
truck and heavy truck and other vehicle body parts, bodies, and cabs is permitted
by rule, provided that all the following conditions of this section are met.
(1) Before construction begins, the facility shall be registered
with the commission's Office of Permitting, Remediation, and Registration
in Austin using Form PI-7-124.
(2) Facilities which satisfy one of the following conditions.
(A) Spray operations that use less than 1/2 pint of coatings
and solvents per hour are exempt from all of the requirements of this section
except for paragraphs (3), (4), (16), and (17) of this section.
(B) Spray operations that use less than two gallons of coatings
and solvents per week are exempt from all of the requirements of this section
except for paragraphs (3), (4), (8), (11), (12), (14), (16), and (17) of this
section unless additional controls are specified in §115.421 of this
title (relating to Emission Specifications). Additionally, all overspray emissions
must be vented through a filter system that meets the requirements of paragraph
(7) of this section.
(3) Good housekeeping is practiced: spills are cleaned
up as soon as possible, equipment is maintained according to manufacturers'
instructions, and property is kept clean. In addition, all waste coatings,
solvents, and spent automotive fluids including, but not limited to, engine
oil, gear oil, transmission fluid, brake fluid, anti-freeze, fresh or waste
fuels, and spray booth filters or water wash sludge are disposed of properly.
Prior to disposal, all liquid waste shall be stored in covered containers.
(4) There are no visible emissions leaving the property.
(5) All spray coating operations which coat more than
nine square feet (one panel) shall be performed in a totally enclosed filtered
spray booth or totally enclosed filtered spray area with an air intake area
of less than 100 square feet. All spray areas shall be equipped with a fan
that achieves one of the following requirements:
(A) a flow capacity of at least 10,000 cubic feet per minute;
(B) a face velocity of at least 100 feet per minute.
(6) All spray coating operations which coat less
than nine square feet (one panel) and are not in a totally enclosed booth
shall be performed on or in a dedicated preparation area which meets the following
requirements.
(A) The preparation area ventilation system shall be operating
during spraying, and the exhaust air shall either be vented through a stack
to the atmosphere or the air shall be recirculated back into the shop through
a carbon adsorption system.
(B) If the preparation area is equipped with a carbon adsorption
system, the carbon shall be replaced at the manufacturer's recommended intervals
to minimize solvent emissions.
(C) The preparation area ventilation system shall be equipped
with a filter or filter system to control paint overspray.
(7) All paint booth, spray area, and preparation
area overspray (exhaust) filters or filter systems shall have a particulate
control efficiency of at least 90%.
(8) High transfer efficiency coating application equipment
shall be used, such as high volume low pressure spray guns. Electrostatic
spray guns or other methods, if demonstrated to provide equivalent or better
transfer efficiency are acceptable.
(9) Cleanup emissions shall be minimized by implementing
the following procedures:
(A) spray and other equipment cleanup is totally enclosed during
washing, rinsing, and draining. Non- enclosed cleaners may be used if the
vapor pressure of the cleaning solvent is less than 100 millimeters of mercury
at 68 degrees Fahrenheit and the solvent is directed toward a drain that leads
directly to a remote reservoir;
(B) all wash solvents are kept in an enclosed reservoir that
is covered at all times, except when being refilled with fresh solvents;
(C) all waste solvents and other cleaning materials are kept
in closed containers.
(10) All spray booth spray area, preparation area,
and shop heaters that are not electrically heated must use pipeline quality
natural gas or liquified petroleum gas only and the heaters are five million
British thermal units per hour or smaller. No firing of waste coatings, solvents,
oils, or other automotive fluids shall be permitted on-site.
(11) All spray booth, spray area, and preparation area
stack heights shall meet the following requirements.
(A) If the stack is located within 200 feet of a building that
is taller than the body shop building, the stack height shall be at least
1.2 times the height of the tallest building or higher as measured from ground
level.
(B) If the stack is located greater than 200 feet from a building
taller than the body shop building, the stack height shall be at least 1.2
times the height of the body shop building as measured from ground level.
(C) If any ground level elevation within 250 feet of the spray
booth stack is greater than the stack height required in subparagraphs (A)
and (B) of this paragraph, this section cannot be used.
(12) Spray booth, spray area, and preparation area
stacks shall be located at least 50 feet away from any residence, recreation
area, church, school, child care facility, or medical or dental facility.
(13) Rain caps, goose neck exhaust, or other stack heads
that would restrict or obstruct vertical discharge of air contaminants shall
not be allowed.
(14) The volatile organic compound (VOC) content limits
specified in §115.421 of this title, concerning automobile and light-duty
truck coatings, shall apply to the facility regardless of its location.
(15) Definitions of the coating types specified in subparagraphs
(A) - (H) of this paragraph are based on §115.10 of this title (relating
to Definitions), and the VOC content limits shall be those listed in §115.421
of this title. Shop use of the coating categories listed in subparagraphs
(A) - (H) of this paragraph in gallons per month shall not be exceeded:
(A) cleanup solvents--50 gallons per month;
(B) wipe solvents--50;
(C) precoat--50;
(D) pretreatment--50;
(E) sealers--50;
(F) primers/primer surfacer--175;
(G) top coats--320;
(H) specialty coatings--50.
(16) The following records and reports shall be maintained
at the shop site for a consecutive 24-month period and be made immediately
available upon request of personnel from the commission or any other air pollution
control agency with jurisdiction:
(A) material safety data sheet (MSDS) or other coating data
sheets on paint and solvent systems used during the previous 24-month period
or currently in use at the shop. The MSDS or coating data sheets should clearly
indicate the VOC content of the product and the VOC content of multiple component
coatings when mixed according to manufacturers instructions;
(B) records of monthly coating and solvent purchases (invoices
from suppliers are acceptable);
(C) records of monthly paint and solvent use if purchase volumes
are above the levels specified for any category in paragraph (15) of this
section;
(D) additional records are kept in sufficient detail, if necessary,
to allow an annual emission inventory to be submitted according to the requirements
in §101.10 of this title (relating to Emissions Inventory Requirements);
(E) records of the United States Environmental Protection Agency
and the commission's Office of Permitting, Remediation, and Registration registration
or identification numbers for each waste generator.
(17) Compliance with the requirements of this section
does not eliminate the requirement to comply with all rules of the commission,
including §101.4 of this title (relating to Nuisance). The commission
may require a facility to cease operation until the matter is resolved.
(18) After December 31, 1994, the conditions of this permit
by rule are effective as to facilities in existence prior to the adoption
of this section.
