What is the EPA docket number for this project?

The EPA docket number for this project is EPA-R06-OAR-2013-0804, and multiple TCEQ 

project numbers are associated with this EPA docket. These TCEQ project numbers are as 

follows: 2013-012-115-AI, 2010-016-115-EN, 2006-027-SIP-NR, 2006-013-SIP-NR, 2009-017-

SIP-NR, 2009-021-SIP-NR, 2010-028-SIP-NR, and 2010-022-SIP-NR. 

What EPA document contains a list of questions and answers concerning relationship of 

the 1-Hour RACT and the 1997 8-Hour RACT?

The May 18, 2006 Memorandum from William T. Harnett, Director, Air Quality Policy Division 

to Regional Air Division Directors titled “RACT Qs & As – Reasonably Available Control 
3 

Technology (RACT): Questions and Answers” (EPA’s May 18, 2006 RACT Q and A document) 

explains the relationship of the 1-Hour RACT and the 1997 8-Hour RACT in the form of a series 

of questions and answers. This document is available at 

http://www.epa.gov/ttn/oarpg/t1/memoranda/ractqanda.pdf (URL dating June 12, 2012). 

Does this rulemaking action only apply to the nonattainment areas? 

Although, this project mainly concerns the Houston-Galveston-Brazoria and Dallas-Fort Worth 

1997 8-Hour ozone nonattainment areas (because according to section 182 of the Act, the RACT 

applies to the moderate and above nonattainment areas), some of the rule revisions associated 

with this project apply to other geographical areas, as well. See section 115.430(a) below: 

“§115.430. Applicability and Definitions. 

(a) Applicability. The requirements in this division apply to the following flexographic and 

rotogravure printing processes in the Beaumont-Port Arthur, Dallas-Fort Worth, El Paso, 

and Houston-Galveston-Brazoria areas, as defined in §115.10 of this title (relating to 

Definitions), and in Gregg, Nueces, and Victoria Counties: 

(1) packaging rotogravure printing lines; 

(2) publication rotogravure printing lines; 

(3) flexographic printing lines; and 

(4) flexible package printing lines.” 

As you can see, in addition to the DFW, and HGB areas, section 115.430(a) also applies to the 

Beaumont-Port Arthur area, and El Paso, Gregg, Nueces, and Victoria Counties in Texas (as a 

rule, but not as RACT). 

Submittals and Our Action: 

The December 6, 2013 submittal concerns rule revisions to 30 TAC, Chapter 115 Control of Air 

Pollution from Volatile Organic Compounds for solvent using processes and surface coating 

application systems. We are proposing to approve all of this submittal. 

The January 17, 2012 submittal concerns rule revisions to 30 TAC, Chapter 115 Control of Air 

Pollution from Volatile Organic Compounds intended to implement RACT for both HGB and 

DFW areas. The submittal will limit VOC content of coatings and solvents used in Flexible 

Package Printing, Industrial Cleaning Solvents, Large Appliance Coatings, Metal Furniture 
4 

Coatings, Paper, Film, and Foil Coatings, Miscellaneous Industrial Adhesives, Automobile and 

Light-Duty Truck Assembly Coatings, and Miscellaneous Metal and Plastic Parts Coatings 

operations. We are proposing to approve all of this submittal. 

 

Another submittal also dated January 17, 2012 contains a corresponding analysis to demonstrate 

RACT is being implemented for certain categories. Specifically, we are proposing to approve the 

demonstration for the Flexographic and Rotogravure Printing sector for the HGB area of the 

RACT-related rule revisions which was not approved in past actions. 

A third SIP submittal dated January 17, 2012 (TCEQ Rule Project No. 2010-022-SIP-NR) 

contains RACT analysis for the DFW area. As a result of this submittal, and consistent with 

section 182(c) of the Act, the VOC or NOx major source threshold in the DFW area is lowered 

to 50 Tons Per Year (TPY) from 100 TPY for RACT purposes under the 1997 8-Hour ozone 

standard. See EPA-R06-OAR-2012-0098 at www.regulations.gov. We are proposing to approve 

the RACT analysis portion of this submittal. 

The April 6, 2010 submittal is an HGB attainment demonstration revision, and contains an 

appendix D, titled “Reasonably Available Control Technology Analysis.” The appendix includes 

source categories affected by the newly EPA-issued Control Techniques Guidelines (CTGs), and 

NOx emissions sources. We are proposing to approve the RACT analysis portion of this 

submittal. 

The June 13, 2007 submittal concerns revisions to 30 TAC, Chapter 115 Control of Air Pollution 

from Volatile Organic Compounds to control selected categories. The June 13, 2007 submittal 

also included an analysis intended to demonstrate RACT was being implemented in the HGB 

area as required by the CAA (Appendix B of the submittal). We are proposing to approve the 

RACT analysis portion of this submittal. 

The Flexographic and Rotogravure Printing sector was not specifically identified in the April 15, 

2014 (79 FR 21144) rulemaking action for the HGB area. The 30 TAC Chapter 115 sections 430 

through 439 fulfill the VOC control requirements for this particular sector. For a section-by-
5 

section evaluation of this sector see part 1 of the TSD. We are proposing to approve the VOC 

RACT for the Flexographic and Rotogravure Printing operations in the HGB area. 

On August 4, 2014 (79 FR 45105) we approved RACT for the Offset Lithographic Printing 

Operations in the DFW (Serious) and HGB (Severe) areas. Also, see docket No. EPA-R06-OAR2010-0332 at www.regulations.gov. 

On September 9, 2014 (79 FR 53299) we approved revisions to 30 TAC Chapter 115 for control 

of VOC emissions for storage tanks in the DFW and HGB areas. In that rulemaking action, we 

also found that VOC control requirements for the VOC storage tanks source category in the 

DFW (Serious) and HGB (Severe) areas represent RACT. See docket No. EPA-R06-OAR-2012-

0096 at www.regulations.gov. 

In consideration of the above proposals and RACT rule revisions previously approved for Texas, 

taken together, we are we are proposing to approve Texas’ RACT analysis as demonstrating the 

RACT requirements for all affected VOC and NOx sources for the DFW and HGB areas for the 

1997 8-Hour ozone standard are met. 

None of the SIP submittals associated with this project contained materials designated as 

Confidential Business Information (CBI).

 Part 1: Houston Galveston Brazoria (HGB) 

A. Volatile Organic Compounds (VOC) 

The EPA had previously approved RACT for VOC and Oxides of Nitrogen (NOx) into Texas’ 

SIP under the 1-Hour ozone standard. On April 2, 2013 (78 FR 19599), April 15, 2014 (79 FR 

(79 FR 21144), and August 4, 2014 (79 FR 45105) we finalized approval of RACT for 

numerous VOC emitting sectors in the HGB area under the 1997 8-Hour ozone National 

Ambient Air Quality Standard (NAAQS). 

The Control Technique Guidelines (CTG) categories not included in the April 2, 2013 (78 FR 

19599), the April 15, 2014 (79 FR 21144), and the August 4, 2014 (79 FR 45105) rulemaking 

actions are included here. 

The January 17, 2012 Rule Project No. 2010-016-115-EN; January 17, 2012 Rule Project No. 

2010-028-SIP-NR; and December 6, 2013 Rule Project No. 2013-012-115-AI are among a series 

of submittals that address the CTG documents EPA issued between 2006 and 2008 with 

recommendations for VOC controls on a variety of sources. Some of the new CTG 

recommendations are updates to previously-issued CTG documents, and some are 

recommendations for new categories. The TCEQ evaluated these new CTG documents in its 

RACT analysis to determine if additional VOC controls were necessary to fulfill RACT 

requirements. 

What are the latest source categories that EPA issued CTGs for? 

The following Table A is a list of these 11 CTG documents that EPA issued between 2006 and 

2008.

be evaluated later in this document. 

What Framework did Texas use to conduct its RACT analysis? 
8 

Texas submitted a RACT assessment with its SIP revisions of Chapter 115. Texas evaluated its 

existing RACT regulations which were federally approved and adopted to meet the 1-hour ozone 

standard to ascertain whether these regulations constitute RACT for the new 8-hour ozone 

NAAQS. Texas’ 8-Hour ozone RACT SIP submittals are based on the determination that RACT 

has been met either through a certification that previously required RACT controls for the 1-hour 

ozone standard represent RACT for 8-hour ozone implementation purposes or, where necessary, 

through a new RACT evaluation for certain regulations or sources. See section 3.3.2 of 

Appendix D, April 6, 2010 submittal. In making its 8-Hour ozone RACT determination, Texas 

also relied on EPA’s May 18, 2006 RACT Q and A document. See section 3.3 of Appendix D, 

April 6, 2010 submittal. Accordingly, the framework for Texas’ RACT SIP determination is to: 

 Identify all source categories covered by Control Technique Guidelines (CTG) and 

Alternative Control Technique (ACT) documents. 

 Identify applicable regulations that implement RACT. 

 Certify that the existing level of controls for the 1-hour ozone standard equals RACT 

under the 8-hour ozone standard, or 

 Declare that sources covered by a CTG and ACT do not exist within the state and/or 

that RACT is not applicable in certain cases, or 

 Identify potential RACT revisions necessary to implement RACT. 

For what source categories, in the HGB Area, did Texas announce a negative declaration? 

Texas declared that the Fiberglass Boat Manufacturing Materials Operations, Leather Tanning 

and Finishing Operations, Surface Coating for Flat Wood Paneling Operations, Automobile and 

Light-Duty Truck Assembly Coating Operations, Letterpress Printing Operations (not the 

Lithographic Printing), and Vegetable Oil Manufacturing Operations do not exist or are not 

major sources in the HGB Area. As such, TCEQ does not have to adopt VOC regulations 

relevant to these source categories at this time for the HGB Area for 1997 8-Hour ozone 

standard. As a part of 72 FR 58063 (September 19, 2010) RACT rulemaking action we approved 

a negative declaration for the Rubber Tire Manufacturing Operations in the HGB Area. 
9 

For a list of negative declarations see section D of the April 15, 2014 (79 FR 21144). Also see 40 

CFR 52.2270(e), second Table titled “EPA Approved Nonregulatory Provisions and QuasiRegulatory Measures in the Texas SIP.” 

What is our review of Texas’ RACT analysis? 

By approving RACT under the 1-Hour ozone standard (70 FR 58136, October 5, 2005; and 71 

FR 52676, September 6, 2006) we found that control measures in 30 TAC Chapter 115 meet the 

lowest emissions limitation that a particular source is capable of meeting by the application of 

control technology that is reasonably available, considering technological and economic 

feasibility at that time. EPA’s May 18, 2006 RACT Q and A document (guidance document) 

recommends a State certify after review that its regulations continue to represent RACT for the 

1997 8-Hour ozone NAAQS. The May 18, 2006 guidance document clarifies the implementation 

of RACT-related SIPs under the 8-Hour ozone NAAQS by using a Question-and-Answer format. 

See Section B, Pages 4-5, of the guidance document titled Certifications. We are including this 

guidance document in the docket for this rulemaking action. The certification approach is in 

agreement with the 70 FR 71612, November 29, 2008 (Final Rule to Implement the 8-Hour 

Ozone NAAQS). We have also approved that VOC control measures in 30 TAC Chapter 115 

meet RACT under the 8-Hour ozone standard for numerous categories in the HGB Area on April 

2, 2013 at 78 FR 19599, on April 15, 2014 at 79 FR 21144, and on August 4, 2014 (79 FR 

45105). 

Additionally, in our April 2, 2013 (78 FR 19599) we approved that major Non-CTG sources of 

VOC in the HGB area meet RACT requirements. See section E of the April 2, 2013 (78 FR 

19599). Also, see the September 19, 2012 (77 FR 58063). Therefore, no further action for major 

Non-CTG sources of VOC in the HGB area is needed here. 

Each individual entry (row) from the above Table A is discussed below for HGB Area RACT 

purposes: 

1 Flat Wood Paneling 

Coatings 

Group II Issued by EPA in 2006, 

Control Techniques Guidelines for 

No such a major source 

in HGB Area. 
10 

Flat Wood Paneling Coatings, (EPA453/R-06-004-2006/09)

There are no applicable sources of VOC located or operating in the HGB 1997 8-Hour ozone 

nonattainment area for the Flat Wood Paneling Coatings operations. We are proposing to 

approve a negative declaration for this sector. This approach is permissible within the above 

identified frame work and is in agreement with the 70 FR 71612, November 29, 2008 (Final Rule 

to Implement the 8-Hour Ozone NAAQS). No further evaluation is needed here. 

2 Flexible Packaging Printing Materials Group II Issued by EPA in 2006, Control 

Techniques Guidelines for Flexible Package 

Printing, (EPA-453/R-06-003-2006/09)

Section 115.430 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.431 states what sources in terms of their threshold values are not subject to these 

requirements. 

Section 115.432 establishes what control requirements are for the affected sources. For example; 

owner or operator of a flexographic printing line shall use either of the following options: low 

solvent ink with a volatile fraction containing 25% by volume or less of VOC solvent and 75% by 

volume or more of water and exempt solvent; apply high solids solvent-borne ink containing 60% 

by volume or more of nonvolatile material (minus water and exempt solvent); operate a vapor 

control system to reduce the VOC emissions from an effective capture system by at least 90% by 

weight. See 115.432(a)(1)(A), (B), and (C). 

Section 115.433 provides for the affected sources in the HGB area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.435 sets forth Test Methods are to determine compliance. Among these methods are 

EPA Test Methods 1 - 4 (40 Code of Federal Regulations (CFR) Part 60, Appendix A) for 

determining flow rates; Method 24 for determining the volatile organic compounds (VOC) content 

and density of printing inks and related coatings; Method 25 for determining total gaseous non-
11 

methane organic emissions as carbon; and Methods 25A or 25B for determining total gaseous 

organic concentrations using flame ionization or non-dispersive infrared analysis. 

Section 115.436 establishes monitoring and recordkeeping requirements an affected source in the 

HGB area will need to comply with. This section will facilitate inspection and enforcement of 

the rule. 

Section 115.439 sets forth the compliance schedule for the HGB area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 

provisions of this sector. 

Sections 115.430-439 will provide for controlling VOC emissions from this sector. We have 

previously stated that VOC and NOx RACT requirements under the Act are in place for the HGB 

area for the 1-Hour ozone NAAQS (70 FR 58136, October 5, 2005; and 71 FR 52676, 

September 6, 2006). We are finding that these control measures are consistent with those 

described in EPA’s Control Techniques Guidelines for Flexible Package Printing, (EPA-453/R06-003-2006/09) recommended controls. Based on EPA’s May 18, 2006 RACT Q and A 

document, the framework described above, and TCEQ’s certification, a permissible approach per 

70 FR 71612, November 29, 2008, that its level of control meets RACT we are proposing that 

the requirements established in sections 115.430-439 represent RACT for this sector under the 8-

Hour ozone NAAQS. 

3 Industrial Cleaning Solvents Group II Issued by EPA in 2006, Control 

Techniques Guidelines for Industrial 

Cleaning Solvents, (EPA-453/R-06-001-

2006/09) 

Section 115.460 sets forth what sources in the affected area are subject to control requirements 

and establishes the terms of definitions. 

Section 115.461 states what sources in terms of their threshold values (For example; if total use 

for the property is less than 160 fluid ounces per day) are not subject to these requirements. 

Section 115.463 sets forth what the control requirements for affected source are. For example; 

owner or operator shall limit the VOC content of cleaning solutions to: 0.42 pound of VOC per 
12 

gallon of solution, as applied; or limit the composite partial vapor pressure of the cleaning solution 

to 8.0 millimeters of mercury at 20 degrees Celsius (68 degrees Fahrenheit). 

Section 115.464 provides for the affected sources in the HGB area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.465 sets forth Test Methods are to determine compliance. Among these methods are 

EPA Test Methods 24 ; American Society for Testing and Materials Method D2879, Standard Test 

Method for Vapor Pressure-Temperature Relationship and Initial Decomposition Temperature of 

Liquids by Isoteniscope to demonstrate compliance with the partial vapor pressure of the cleaning 

solution limit. 

Section 115.468 establishes monitoring and recordkeeping requirements an affected source in the 

HGB area will need to comply with. For example; owner or operator shall install and maintain 

control device such that in accordance with design specifications, including: continuous 

monitoring of the exhaust gas temperature immediately downstream of direct-flame incinerators or 

the gas temperature immediately upstream and downstream of any catalyst bed; the total amount of 

volatile organic compounds (VOC) recovered by carbon adsorption or other solvent recovery 

systems during a calendar month; and continuous monitoring of carbon adsorption bed exhaust. 

See 115.468(a)(1) through (3). This section will facilitate inspection and enforcement of the rule. 

Section 115.469 sets forth the compliance schedule for the HGB area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 

provisions of this sector. The compliance date for this sector is identified as on or after March 1, 

2013. 

Sections 115.460-469 will provide for controlling VOC emissions from this sector. 

We have previously stated that VOC and NOx RACT requirements under the Act are in place for 

the HGB area for the 1-Hour ozone NAAQS (70 FR 58136, October 5, 2005; and 71 FR 52676, 

September 6, 2006). We are finding that these control measures are consistent with those 

described in EPA’s Control Techniques Guidelines for Industrial Cleaning Solvents, (EPA453/R-06-001-2006/09) recommended controls. Based on EPA’s May 18, 2006 RACT Q and A 

document, the framework described above, and TCEQ’s certification, a permissible approach per 

70 FR 71612, November 29, 2008, that its level of control meets RACT we are proposing that 
13 

the requirements established in sections 115.460-469 represent RACT for this sector under the 8-

Hour ozone NAAQS. 

4 Offset Lithographic and 

Letterpress Printing 

Group II Issued by EPA in 2006, Control 

Techniques Guidelines for Offset 

Lithographic Printing and Letterpress 

Printing, (EPA-453/R-06-002-2006/09) 

According to TCEQ there are no Letterpress Printing operating in the HGB Area. EPA approved 

the Offset Lithographic portion of the submittal as RACT under rule project No. 2008-019-115-

EN. See 79 FR 45105 of August 4, 2014. 

We are proposing to approve a negative declaration for the Letterpress Printing operations in the 

HGB Area. No further evaluation for this sector is needed here. 

5 Large Appliance Coatings Group III Issued by EPA in 2007, Control 

Techniques Guidelines for Large Appliance 

Coatings, (EPA 453/R-07-004-2007/09) 

Section 115.450 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.451 states what sources in terms of their threshold values (For example; surface 

coating processes on a property that, when uncontrolled, will emit a combined weight of VOC of 

less than 3.0 pounds per hour and 15 pounds in any consecutive 24-hour period; or emit, when 

uncontrolled, a combined weight of VOC of less than 100 pounds in any consecutive 24-hour 

period) are not subject to these requirements. 

Section 115.453 sets forth what the control requirements for affected source are. For large 

appliance coatings the affected source will need to meet the limits established in Figure: 30 TAC 

§115.453(a)(1)(A) Tables 1 and 2. If a coating meets more than one coating type definition, then 

the coating with the least stringent VOC limit applies. 
14 

Section 115.454 provides for the affected sources in the HGB area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.455 sets forth Test Methods are to determine compliance. Among these methods are 

EPA Test Methods Method 24 for determining VOC limit; ASTM Test Methods D1186-06.01, 

D1200-06.01, D3794-06.01, D2832-69, D1644-75, and D3960-81; and additional test procedures 

described in 40 CFR §60.446 (as amended through October 17, 2000 (65 FR 61761)). Adoption of 

these methods will facilitate compliance determination. 

Section 115.458 establishes monitoring and recordkeeping requirements an affected source in the 

HGB area will need to comply with. The owner or operator shall install and maintain monitors to 

accurately measure and record operational parameters of all required control devices to ensure the 

proper functioning of those devices in accordance with design specifications. Among these 

parameters, as applicable, are: continuous monitoring of the exhaust gas temperature immediately 

downstream of direct-flame incinerators or the gas temperature immediately upstream and 

downstream of any catalyst bed; the total amount of VOC recovered by carbon adsorption or other 

solvent recovery systems during a calendar month; continuous monitoring of carbon adsorption bed 

exhaust; and appropriate operating parameters for capture systems and control devices. For 

recordkeeping the owner or operator will need to maintain records of the testing data or the 

material safety data sheets (MSDS). Furthermore, records must be maintained of the quantity and 

type of each coating and solvent consumed during the specified averaging period if any of the 

coatings, as delivered to the coating application system, exceed the applicable VOC limits. Such 

records must be sufficient to calculate the applicable weighted average of VOC content for all 

coatings. Records must be maintained a minimum of two years and be made available upon request 

to authorized representatives of the executive director, the USEPA, or any local air pollution 

agency with jurisdiction. This provision will assist with compliance determination and 

enforcement of the rule. 

Section 115.459 sets forth the compliance schedule for the HGB area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 

provisions of this sector. The owner or operator of a surface coating process shall comply with 

these requirements on or after March 1, 2013. 

Sections 115.450-459 will provide for controlling VOC emissions from this sector. 
15 

We have previously stated that VOC and NOx RACT requirements under the Act are in place for 

the HGB area for the 1-Hour ozone NAAQS (70 FR 58136, October 5, 2005; and 71 FR 52676, 

September 6, 2006). We are finding that these control measures are consistent with those 

described in EPA’s Control Techniques Guidelines for Large Appliance Coatings, (EPA 453/R07-004-2007/09) recommended controls. Based on EPA’s May 18, 2006 RACT Q and A 

document, the framework described above, and TCEQ’s certification, a permissible approach per 

70 FR 71612, November 29, 2008, that its level of control meets RACT we are proposing that 

the requirements established in sections 115.450-459 represent RACT for this sector under the 8-

Hour ozone NAAQS. 

6 Metal Furniture Coatings Group III Issued by EPA in 2007, Control 

Techniques Guidelines for Metal Furniture 

Coatings, (EPA 453/R-07-005-2007/09) 

Section 115.450 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.451 states what sources in terms of their threshold values (For example; surface 

coating processes on a property that, when uncontrolled, will emit a combined weight of VOC of 

less than 3.0 pounds per hour and 15 pounds in any consecutive 24-hour period; or emit, when 

uncontrolled, a combined weight of VOC of less than 100 pounds in any consecutive 24-hour 

period) are not subject to these requirements. 

Section 115.453 sets forth what the control requirements for affected source are. For metal 

furniture the affected source will need to meet the limits established in Figure: 30 TAC 

§115.453(a)(1)(B) Tables 1 and 2. If a coating meets more than one coating type definition, then 

the coating with the least stringent VOC limit applies. If a coating does not meet a specific coating 

type definition, then it can be assumed to be a general-use coating and the VOC limit for general 

coating applies. 

Section 115.454 provides for the affected sources in the HGB area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.455 sets forth Test Methods are to determine compliance. Among these methods are 

EPA Test Methods Method 24 for determining VOC limit; ASTM Test Methods D1186-06.01, 
16 

D1200-06.01, D3794-06.01, D2832-69, D1644-75, and D3960-81; and additional test procedures 

described in 40 CFR §60.446 (as amended through October 17, 2000 (65 FR 61761)). Adoption of 

these methods will facilitate compliance determination. 

Section 115.458 establishes monitoring and recordkeeping requirements an affected source in the 

HGB area will need to comply with. The owner or operator shall install and maintain monitors to 

accurately measure and record operational parameters of all required control devices to ensure the 

proper functioning of those devices in accordance with design specifications. Among these 

parameters, as applicable, are: continuous monitoring of the exhaust gas temperature immediately 

downstream of direct-flame incinerators or the gas temperature immediately upstream and 

downstream of any catalyst bed; the total amount of VOC recovered by carbon adsorption or other 

solvent recovery systems during a calendar month; continuous monitoring of carbon adsorption bed 

exhaust; and appropriate operating parameters for capture systems and control devices. For 

recordkeeping the owner or operator will need to maintain records of the testing data or the MSDS. 

Furthermore, records must be maintained of the quantity and type of each coating and solvent 

consumed during the specified averaging period if any of the coatings, as delivered to the coating 

application system, exceed the applicable VOC limits. Such records must be sufficient to calculate 

the applicable weighted average of VOC content for all coatings. Records must be maintained a 

minimum of two years and be made available upon request to authorized representatives of the 

executive director, the USEPA, or any local air pollution agency with jurisdiction. This provision 

will assist with compliance determination and enforcement of the rule. 

Section 115.459 sets forth the compliance schedule for the HGB area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 

provisions of this sector. The owner or operator of a surface coating process shall comply with 

these requirements on or after March 1, 2013. 

Sections 115.450-459 will provide for controlling VOC emissions from this sector. 

We have previously stated that VOC and NOx RACT requirements under the Act are in place for 

the HGB area for the 1-Hour ozone NAAQS (70 FR 58136, October 5, 2005; and 71 FR 52676, 

September 6, 2006). We are finding that these control measures are consistent with those 

described in EPA’s Control Techniques Guidelines for Metal Furniture Coatings, (EPA 453/R07-005-2007/09) recommended controls. Based on EPA’s May 18, 2006 RACT Q and A 

document, the framework described above, and TCEQ’s certification, a permissible approach per 
17 

70 FR 71612, November 29, 2008, that its level of control meets RACT we are proposing that 

the requirements established in sections 115.450-459 represent RACT for this sector under the 8-

Hour ozone NAAQS. 

7 Paper, Film, and Foil Coatings Group III Issued by EPA in 2007, Control 

Techniques Guidelines for Paper, Film, and 

Foil Coatings, (EPA 453/R-07-003-

2007/09) 

Section 115.422(7) sets forth the control requirements specific to the paper, film, and foil coating 

processes in the HGB area so that starting March 1, 2013 the owner or operator of a paper surface 

coating line must implement certain work practices to limit VOC emissions from storage, mixing, 

and handling of cleaning and cleaning-related waste materials. Among these work practices are: 

all VOC-containing cleaning materials must be stored in closed Containers; mixing and storage 

containers used for VOC-containing materials must be kept closed at all times except when 

depositing or removing these materials; spills of VOC-containing cleaning materials must be 

minimized; VOC-containing cleaning materials must be conveyed from one location to another in 

closed containers or pipes; and VOC emissions from the cleaning of storage, mixing, and conveying 

equipment must be minimized. 

Section 115.450 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.451 states what sources in terms of their threshold values (For example; surface 

coating processes on a property that, when uncontrolled, will emit a combined weight of VOC of 

less than 3.0 pounds per hour and 15 pounds in any consecutive 24-hour period; or emit, when 

uncontrolled, a combined weight of VOC of less than 100 pounds in any consecutive 24-hour 

period) are not subject to these requirements. 

Section 115.453 sets forth what the control requirements for affected source are. For paper, film, 

and foil surface coating the affected source will need to meet the limits established in Figure: 30 

TAC §115.453(a)(4). If a coating meets more than one coating type definition, then the coating 

with the least stringent VOC limit applies. If a coating does not meet a specific coating type 
18 

definition, then it can be assumed to be a general-use coating and the VOC limit for general coating 

applies. 

Section 115.454 provides for the affected sources in the HGB area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.455 sets forth Test Methods are to determine compliance. Among these methods are

06.01, D3794-06.01, D2832-69, D1644-75, and D3960-81; and additional test procedures 

described in 40 CFR §60.446 (as amended through October 17, 2000 (65 FR 61761)). Adoption of 

these methods will facilitate compliance determination. 

Section 115.458 establishes monitoring and recordkeeping requirements an affected source in the 

HGB area will need to comply with. The owner or operator shall install and maintain monitors to 

accurately measure and record operational parameters of all required control devices to ensure the 

proper functioning of those devices in accordance with design specifications. Among these 

parameters, as applicable, are: continuous monitoring of the exhaust gas temperature immediately 

downstream of direct-flame incinerators or the gas temperature immediately upstream and 

downstream of any catalyst bed; the total amount of VOC recovered by carbon adsorption or other 

solvent recovery systems during a calendar month; continuous monitoring of carbon adsorption bed 

exhaust; and appropriate operating parameters for capture systems and control devices. 

Recordkeeping provisions require the owner or operator will need to maintain records of the testing 

data or the MSDS. Furthermore, records must be maintained of the quantity and type of each 

coating and solvent consumed during the specified averaging period if any of the coatings, as 

delivered to the coating application system, exceed the applicable VOC limits. Such records must 

be sufficient to calculate the applicable weighted average of VOC content for all coatings. Records 

must be maintained a minimum of two years and be made available upon request to authorized 

representatives of the executive director, the USEPA, or any local air pollution agency with 

jurisdiction. This provision will assist with compliance determination and enforcement of the 

rule. 

Section 115.459 sets forth the compliance schedule for the HGB area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 
19 

provisions of this sector. The owner or operator of a surface coating process shall comply with 

these requirements on or after March 1, 2013. 

Sections 115.422(7) and 115.450-459 will provide for controlling VOC emissions from this 

sector. 

We have previously stated that VOC and NOx RACT requirements under the Act are in place for

10 Miscellaneous Industrial 

Adhesives 

Group IV Issued by EPA in 2008, Control 

Techniques Guidelines for Miscellaneous 

Industrial Adhesives, (EPA 453/R-08-005-

2008/09)

Section 115.470 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.471 states what sources (For example; processes using adhesives and adhesive 

primers that are supplied to the manufacturer in containers with a net volume of 16 ounces or less 

or a net weight of 1.0 pound or less; or adhesives or adhesive primers being tested or evaluated in 

any research and development, quality assurance, or analytical laboratory) are not subject to these 

requirements. 

Section 115.473 sets forth what the control requirements for affected source are. These limits are 

based on the daily weighted average of all adhesives or adhesive primers delivered to the 

application system each day. If an adhesive or adhesive primer is used to bond dissimilar substrates 

together, then the applicable substrate category with the least stringent VOC content limit applies. 

The owner or operator of an affected source will need to meet the limits established in Figure: 30 

TAC §115.473(a), Tables 1, 2, and 3. As an alternative, the owner or operator may operate a vapor 

control system capable of achieving an overall control efficiency of 85% of the VOC emissions 

from adhesives and adhesive primers. 

Section 115.474 provides for the affected sources in the HGB area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.475 sets forth Test Methods and testing requirements are to determine compliance. 
21 

Among these methods are EPA Test Method 24, Methods 1 - 4, Method 25, Method 25A or 25B. 

Compliance with the VOC content limits for reactive adhesives must be determined using 40 CFR 

Part 63, Subpart PPPP, Appendix A, (as amended through April 24, 2007 (72 FR 20237)). In 

addition, the owner or operator shall measure the capture efficiency using the applicable 

procedures outlined in 40 CFR §52.741, Subpart O, Appendix B (as amended through October 21, 

1996 (61 FR 54559)). These procedures are: Procedure T-Criteria for and Verification of a 

Permanent or Temporary Total Enclosure; Procedure L - VOC Input; Procedure G.2 - Captured 

VOC Emissions (Dilution Technique); Procedure F.1 - Fugitive VOC Emissions from Temporary 

Enclosures; and Procedure F.2 - Fugitive VOC Emissions from Building Enclosures. 

Section 115.478 establishes monitoring and recordkeeping requirements an affected source in the 

HGB area will need to comply with. The owner or operator shall install and maintain monitors to 

accurately measure and record operational parameters of all required control devices to ensure the 

proper functioning of those devices in accordance with design specifications. Among these 

parameters, as applicable, are: continuous monitoring of the exhaust gas temperature immediately 

downstream of direct-flame incinerators or the gas temperature immediately upstream and 

downstream of any catalyst bed; the total amount of VOC recovered by carbon adsorption or other 

solvent recovery systems during a calendar month; and continuous monitoring of carbon adsorption 

bed exhaust. The owner or operator shall maintain records of the testing data or the MSDS to 

comply with the approved test methods and testing requirements. 

Records must be sufficient to demonstrate continuous compliance with the VOC limits. The 

owner or operator of an application process claiming an exemption must maintain records 

sufficient to demonstrate continuous compliance with the applicable exemption criteria; and must 

maintain records of any testing conducted at an affected facility. Records must be maintained a 

minimum of two years and made available upon request to authorized representatives of TCEQ, 

USEPA, or any local air pollution agency with jurisdiction. This provision will assist with 

compliance determination and enforcement of the rule. 

Section 115.479 sets forth the compliance schedule for the HGB area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 

provisions of this sector. The owner or operator of a surface coating process shall comply with 

these requirements on or after March 1, 2013. 
22 

Sections 115.470-479 will provide for controlling VOC emissions from this sector. 

We have previously stated that VOC and NOx RACT requirements under the Act are in place for 

the HGB area for the 1-Hour ozone NAAQS (70 FR 58136, October 5, 2005; and 71 FR 52676, 

September 6, 2006). We are finding that these control measures are consistent with those 

described in EPA’s Control Techniques Guidelines for Miscellaneous Industrial Adhesives, 

(EPA 453/R-08-005-2008/09) recommended controls. Based on EPA’s May 18, 2006 RACT Q 

and A document, the framework described above, and TCEQ’s certification, a permissible 

approach per 70 FR 71612, November 29, 2008, that its level of control meets RACT we are 

proposing that the requirements established in sections 115.470-479 represent RACT for this 

sector under the 8-Hour ozone NAAQS. 

11 Miscellaneous Metal and Plastic 

Parts Coatings 

Group IV Issued by EPA in 2008, Control 

Techniques Guidelines for Miscellaneous 

Metal and Plastic Parts Coatings, (EPA 

453/R-08-003-2008/09)

Section 115.427(a)(8) specifies that for exemption purposes for miscellaneous metal and plastic 

parts coatings sector in the HGB area a designated on-site maintenance shop is an area at a site 

where used miscellaneous metal parts or products are re-coated on a routine basis. This provision 

will assist with compliance determination. 

Section 115.450 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.451 states what sources in terms of their threshold values (For example; surface 

coating processes on a property that, when uncontrolled, will emit a combined weight of VOC of 

less than 3.0 pounds per hour and 15 pounds in any consecutive 24-hour period; or emit, when 

uncontrolled, a combined weight of VOC of less than 100 pounds in any consecutive 24-hour 

period) are not subject to these requirements. 

Section 115.453 sets forth what the control requirements for affected source are. For 

miscellaneous metal parts and products coatings the affected source will need to meet the limits 

established in Figure: 30 TAC§115.453(a)(1)(C), Tables 1 and 2. For miscellaneous plastic parts 

and products coatings the affected source will need to meet the limits established in Figure: 30 
23 

TAC§115.453(a)(1)(D), Tables 1 and 2. If a coating meets more than one coating type definition, 

then the coating with the least stringent VOC limit applies. If a coating does not meet a specific 

coating type definition, then it can be assumed to be a general-use coating and the VOC limit for 

general coating applies. 

Section 115.454 provides for the affected sources in the HGB area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.455 sets forth Test Methods are to determine compliance. Among these methods are 

EPA Test Methods Method 24 for determining VOC limit; ASTM Test Methods D1186-06.01, 

D1200-06.01, D3794-06.01, D2832-69, D1644-75, and D3960-81; and additional test procedures 

described in 40 CFR §60.446 (as amended through October 17, 2000 (65 FR 61761)). Adoption of 

these methods will facilitate compliance determination. 

Section 115.458 establishes monitoring and recordkeeping requirements an affected source in the 

HGB area will need to comply with. The owner or operator shall install and maintain monitors to 

accurately measure and record operational parameters of all required control devices to ensure the 

proper functioning of those devices in accordance with design specifications. Among these 

parameters, as applicable, are: continuous monitoring of the exhaust gas temperature immediately 

downstream of direct-flame incinerators or the gas temperature immediately upstream and 

downstream of any catalyst bed; the total amount of VOC recovered by carbon adsorption or other 

solvent recovery systems during a calendar month; continuous monitoring of carbon adsorption bed 

exhaust; and appropriate operating parameters for capture systems and control devices. 

Recordkeeping provisions require the owner or operator will need to maintain records of the testing 

data or the MSDS. Furthermore, records must be maintained of the quantity and type of each 

coating and solvent consumed during the specified averaging period if any of the coatings, as 

delivered to the coating application system, exceed the applicable VOC limits. Such records must 

be sufficient to calculate the applicable weighted average of VOC content for all coatings. Records 

must be maintained a minimum of two years and be made available upon request to authorized 

representatives of the executive director, the USEPA, or any local air pollution agency with 

jurisdiction. This provision will assist with compliance determination and enforcement of the 

rule. 
24 

Section 115.459 sets forth the compliance schedule for the HGB area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 

provisions of this sector. The owner or operator of a surface coating process shall comply with 

these requirements on or after March 1, 2013. 

Sections 115. 427(a)(8) and 115.451-459 will provide for controlling VOC emissions from this 

sector. 

We have previously stated that VOC and NOx RACT requirements under the Act are in place for 

the HGB area for the 1-Hour ozone NAAQS (70 FR 58136, October 5, 2005; and 71 FR 52676, 

September 6, 2006). We are finding that these control measures are consistent with those 

described in EPA’s Control Techniques Guidelines for Miscellaneous Metal and Plastic Parts 

Coatings, (EPA 453/R-08-003-2008/09) recommended controls. Based on EPA’s May 18, 2006 

RACT Q and A document, the framework described above, and TCEQ’s certification, a 

permissible approach per 70 FR 71612, November 29, 2008, that its level of control meets 

RACT we are proposing that the requirements established in sections 115. 427(a)(8) and 

115.451-459 represent RACT for this sector under the 8-Hour ozone NAAQS. 

Flexographic and Rotogravure Printing Control of Volatile Organic Emissions from 

Existing Stationary Sources – Volume VIII: 

Graphic Arts-Rotogravure and Flexography, 

(EPA-450/2-78-033-78/12)

The Flexographic and Rotogravure Printing sector was not specifically identified in the April 2, 

2013 (78 FR 19599) proposed rulemaking action. This sector is now reviewed here, instead. 

Section 115.430 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.431 states what sources in terms of their threshold values are not subject to these 

requirements. 

Section 115.432 establishes what control requirements are for the affected sources. For example; 

a flexi package printing owner or operator has a daily weighted average limit of 0.16 pounds of 

VOC per pound of coating applied. This requirement can obtained through use of low VOC 
25 

coatings or a combination of coatings and operation of a vapor control system. The vapor control 

system shall achieve at least 80% overall control efficiency by weight. Equation 30 TAC 

115.432(c)(3) shall be used to determine the minimum overall control efficiency. This section will 

provide for VOC control mechanisms. 

Section 115.433 provides for the affected sources in the HGB area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.435 sets forth Test Methods are to determine compliance. Among these methods are 

EPA Test Methods 1 - 4 (40 Code of Federal Regulations (CFR) Part 60, Appendix A) for 

determining flow rates; Method 24 for determining the volatile organic compounds (VOC) content 

and density of printing inks and related coatings; Method 25 for determining total gaseous nonmethane organic emissions as carbon; and Methods 25A or 25B for determining total gaseous 

organic concentrations using flame ionization or non-dispersive infrared analysis. Test Methods 

are also in conformance with EPA guideline series “Procedures for Certifying Quantity of 

Volatile Organic Compounds Emitted by Paint, Ink, and Other Coatings, EPA-450/3-84-019.” 

Performance test procedures are described in 40 CFR 60.444. These provisions are federally 

enforceable. 

Section 115.436 establishes monitoring and recordkeeping requirements an affected source in the 

HGB area will need to comply with. Among such elements are: maintaining records of VOC 

contents of all inks, quantity of solvents and inks used, daily records of the quantity of each ink, 

installing and maintaining monitors to continuously measure and record operational parameters 

of any control device installed (exit gas temperature, VOC concentration, and capture efficiency 

protocol), and keeping records at the affected facility for two years. This section will facilitate 

inspection and enforcement of the rule. 

Section 115.439 sets forth the compliance schedule effective March 1, 2013 for the HGB area 

that affected sources will need to adhere to the emission specifications; control requirements; and 

recordkeeping provisions of this sector. 

Sections 115.430-439 will provide for controlling VOC emissions from this sector. 

We have previously stated that VOC and NOx RACT requirements under the Act are in place for 

the HGB area for the 1-Hour ozone NAAQS (70 FR 58136, October 5, 2005; and 71 FR 52676, 
26 

September 6, 2006). We are finding that these control measures are consistent with those 

described in EPA’s Control Techniques Guidelines for Graphic Arts-Rotogravure and 

Flexography, (EPA-450/2-78-033-78/12) recommended controls. Based on EPA’s May 18, 2006 

RACT Q and A document, the framework described above, and TCEQ’s certification, a 

permissible approach per 70 FR 71612, November 29, 2008, that its level of control meets 

RACT we are proposing that the requirements established in sections 115.430-439 represent 

RACT for this sector under the 8-Hour ozone NAAQS.

 Part 2: Houston Galveston Brazoria (HGB) 

A. Oxides of Nitrogen (NOx) 

In the April 2, 2013 (78 FR 19599) rulemaking action, we made the finding that Texas has NOx 

RACT in place for the 1997 8-hour ozone NAAQS within the HGB Area. No further action is 

warranted here. 

 
28 

 Conclusion – HGB Part 1 and Part 2: The EPA had previously approved RACT for VOC and 

NOx into Texas’ SIP under the 1-Hour ozone standard, thus finding that, at that time, these 

control measures result in the lowest emissions limitation that a particular source is capable of 

meeting through application of control technology that is reasonably available, considering 

technological and economic feasibility. On April 15, 2014 (79 FR 21144) we finalized approval 

of RACT for all VOC emitting sectors in the HGB Area under the 1997 8-Hour ozone National 

Ambient Air Quality Standard (NAAQS), except for the newly-issued CTGs and the 

Flexographic and Rotogravure Printing operations. 

Based on EPA’s May 18, 2006 RACT Q and A document; the framework identified above; and 

TCEQ’s certification (a permissible approach per 70 FR 71612, November 29, 2008 -Final Rule 

to Implement the 8-Hour Ozone NAAQS) of its RACT we are proposing to approve the 30 TAC 

Chapter 115 control requirements as meeting RACT for newly-issued CTGs in the HGB 1997 8-

Hour ozone nonattainment area. Therefore, by implementing the 30 TAC Chapter 115 control 

requirements Texas has the 8-Hour RACT in place for all affected VOC sources in the HGB 

area. We recommend proposing their approval into Texas SIP. 

 
29 

 Part 3: 

Dallas Fort Worth (DFW) 

Effective June 15, 2004, Collin, Dallas, Denton, Tarrant, Ellis, Johnson, Kaufman, Parker, and 

Rockwall counties were designated nonattainment for the 1997 8-Hour ozone standard. The area 

was then classified as moderate nonattainment for the standard, with an attainment deadline of 

June 15, 2010. 

This RACT-related rulemaking action will review both the Volatile Organic Compounds (VOC), 

and Oxides of Nitrogen (NOx) for the DFW area. See Parts 3(A), and 4(B) of this TSD for the 

VOC and NOx reviews, respectively. 

A. Volatile Organic Compounds (VOC) 

The EPA had previously approved RACT for VOC into Texas’ SIP under the 1-Hour and 8-Hour 

ozone National Ambient Air Quality Standard (NAAQS) on January 14, 2009 (74 FR 1903). 

The EPA-issued Control Technique Guidelines (CTG) categories (the 2006-2008 issued CTGs) 

were not included in the January 14, 2009 (74 FR 1903) rulemaking action for the DFW Area, 

and now we are including the 2006-2008 CTGs here. We are also proposing approval of the 

negative declarations for source categories that reportedly do not exist or operate in the DFW for 

the 1997 8-Hour ozone standard. 

The January 17, 2012 submittal as Rule Project No. 2010-016-115-EN; and another January 17, 

2012 submittal as Rule Project No. 2010-028-SIP-NR; and Project No. 2010-022-SIP-NR are 

among the submittals that address the CTG documents EPA issued between 2006 and 2008 with 

recommendations for VOC controls on a variety of sources. Again, none of the submittals 

mentioned in this TSD contain any CBI material. Some of the new CTG recommendations are 

updates to previously-issued CTG documents and some are recommendations for new categories. 

The TCEQ evaluated these new CTG documents in its RACT analysis to determine if additional 

VOC controls were necessary to fulfill RACT requirements. The following Table B is a list of 

these 11 CTG documents.

The corresponding sections of Chapter 115 for each sector (row) identified in Table B above will 

be evaluated later in this document. 

For what source categories, in the DFW Area, did Texas announce a negative declaration? 

Texas declared that the Fiberglass Boat Manufacturing Materials Operations, Ship Building and 

Ship Repair Coating Operations, Leather Tanning and Finishing Operations, Surface Coating for 

Flat Wood Paneling Operations, Vegetable Oil Manufacturing Operations, Letterpress Printing 

Operations (not the Offset Lithographic), Plywood Veneer Dryers Operations, Rubber Tire 

Manufacturing Operations, and Batch Processes Operations do not exist or are not major sources 

in the DFW Area. As such, TCEQ does not have to adopt VOC regulations relevant to these 

source categories at this time for the DFW Area for 1997 8-Hour ozone standard. This approach 

is in agreement with the 70 FR 71612, November 29, 2008 (Final Rule to Implement the 8-Hour 

Ozone NAAQS). Therefore, we are proposing to approve Texas’ negative declaration for these 

source categories. 

At the State level and as a part of a different rulemaking action (the 2008 ozone NAAQS), TCEQ 

has started preliminary work for another round of RACT analysis for the DFW Area. Once that 

work is completed and made available to EPA, and if a major source of these categories is 

located or operating in the DFW Area, then TCEQ will need to update its negative declaration 

list, and take appropriate regulatory measures for SIP purposes. 

What is our review of Texas’ RACT analysis? 

Each individual entry (row) from the above Table B is discussed below for DFW area RACT

Coatings 

Group II Issued by EPA in 2006, 

Control Techniques Guidelines for

No such a major source 

in HGB Area. 

There are no applicable sources of VOC located or operating in the DFW1997 8-Hour ozone 

nonattainment area for the Flat Wood Paneling Coatings operations. We are proposing to 

approve a negative declaration for this sector. This approach is permissible within the above 

identified frame work and is in agreement with the 70 FR 71612, November 29, 2008 (Final Rule 

to Implement the 8-Hour Ozone NAAQS). No further evaluation is needed here.

2 Flexible Packaging Printing Materials Group II Issued by EPA in 2006, Control 

Techniques Guidelines for Flexible Package 

Printing, (EPA-453/R-06-003-2006/09)

Section 115.430 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.431 states what sources in terms of their threshold values are not subject to these 

requirements. 

Section 115.432 establishes what control requirements are for the affected sources. For example; 

owner or operator of a flexographic printing line shall use either of the following options: low 

solvent ink with a volatile fraction containing 25% by volume or less of VOC solvent and 75% by 

volume or more of water and exempt solvent; apply high solids solvent-borne ink containing 60% 

by volume or more of nonvolatile material (minus water and exempt solvent); operate a vapor 

control system to reduce the VOC emissions from an effective capture system by at least 90% by 

weight. See 115.432(a)(1)(A), (B), and (C). 

Section 115.433 provides for the affected sources in the DFW area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.435 sets forth Test Methods are to determine compliance. Among these methods are 

EPA Test Methods 1 - 4 (40 Code of Federal Regulations (CFR) Part 60, Appendix A) for 

determining flow rates; Method 24 for determining the volatile organic compounds (VOC) content 

and density of printing inks and related coatings; Method 25 for determining total gaseous nonmethane organic emissions as carbon; and Methods 25A or 25B for determining total gaseous 

organic concentrations using flame ionization or non-dispersive infrared analysis. 

Section 115.436 establishes monitoring and recordkeeping requirements an affected source in the 

DFW area will need to comply with. This section will facilitate inspection and enforcement of 

the rule. 

Section 115.439 sets forth the compliance schedule for the DFW area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 

provisions of this sector. 

Sections 115.430-439 will provide for controlling VOC emissions from this sector. 
33 

We have previously stated that VOC RACT requirements under the Act are in place for the DFW 

area for the 1-Hour ozone and 8-Hour NAAQS (January 14, 2009 (74 FR 1903)). We are finding 

that these control measures are consistent with those described in EPA’s Control Techniques 

Guidelines for Flexible Package Printing, (EPA-453/R-06-003-2006/09) recommended controls. 

Based on EPA’s May 18, 2006 RACT Q and A document, the framework described above, and 

TCEQ’s certification, a permissible approach per 70 FR 71612, November 29, 2008, that its level 

of control meets RACT we are proposing that the requirements established in sections 115.430-

439 represent RACT for this sector under the 8-Hour ozone NAAQS. 

3 Industrial Cleaning Solvents Group II Issued by EPA in 2006, Control 

Techniques Guidelines for Industrial 

Cleaning Solvents, (EPA-453/R-06-001-

2006/09) 

Section 115.460 sets forth what sources in the affected area are subject to control requirements 

and establishes the terms of definitions. 

Section 115.461 states what sources in terms of their threshold values (For example; if total use 

for the property is less than 160 fluid ounces per day) are not subject to these requirements. 

Section 115.463 sets forth what the control requirements for affected source are. For example; 

owner or operator shall limit the VOC content of cleaning solutions to: 0.42 pound of VOC per 

gallon of solution, as applied; or limit the composite partial vapor pressure of the cleaning solution 

to 8.0 millimeters of mercury at 20 degrees Celsius (68 degrees Fahrenheit). 

Section 115.464 provides for the affected sources in the DFW area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.465 sets forth Test Methods are to determine compliance. Among these methods are 

EPA Test Methods 24 ; American Society for Testing and Materials Method D2879, Standard Test 

Method for Vapor Pressure-Temperature Relationship and Initial Decomposition Temperature of 

Liquids by Isoteniscope to demonstrate compliance with the partial vapor pressure of the cleaning 

solution limit. 
34 

Section 115.468 establishes monitoring and recordkeeping requirements an affected source in the 

DFW area will need to comply with. For example; owner or operator shall install and maintain 

control device such that in accordance with design specifications, including: continuous 

monitoring of the exhaust gas temperature immediately downstream of direct-flame incinerators or 

the gas temperature immediately upstream and downstream of any catalyst bed; the total amount of 

volatile organic compounds (VOC) recovered by carbon adsorption or other solvent recovery 

systems during a calendar month; and continuous monitoring of carbon adsorption bed exhaust. 

See 115.468(a)(1) through (3). This section will facilitate inspection and enforcement of the rule. 

Section 115.469 sets forth the compliance schedule for the DFW area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 

provisions of this sector. The compliance date for this sector is identified as on or after March 1, 

2013. 

Sections 115.460-469 will provide for controlling VOC emissions from this sector. 

We have previously stated that VOC RACT requirements under the Act are in place for the DFW 

area for the 1-Hour ozone and 8-Hour NAAQS (January 14, 2009 (74 FR 1903)). We are finding 

that these control measures are consistent with those described in EPA’s Control Techniques 

Guidelines for Industrial Cleaning Solvents, (EPA-453/R-06-001-2006/09) recommended 

controls. Based on EPA’s May 18, 2006 RACT Q and A document, the framework described 

above, and TCEQ’s certification, a permissible approach per 70 FR 71612, November 29, 2008, 

that its level of control meets RACT we are proposing that the requirements established in 

sections 115.460-469 represent RACT for this sector under the 8-Hour ozone NAAQS. 

4 Offset Lithographic and 

Letterpress Printing 

Group II Issued by EPA in 2006, Control 

Techniques Guidelines for Offset 

Lithographic Printing and Letterpress 

Printing, (EPA-453/R-06-002-2006/09) 

According to TCEQ there are no Letterpress Printing sources operating in the DFW Area. EPA 

acted on the Offset Lithographic portion of the submittal as RACT under rule project No. 2008-

019-115-EN. See 79 FR 13964 of March 12, 2014. We are proposing to approve a negative 

declaration for the Letterpress Printing operations in the DFW Area. This approach is 
35 

permissible within the above identified frame work and is in agreement with the 70 FR 71612, 

November 29, 2008 (Final Rule to Implement the 8-Hour Ozone NAAQS). No further evaluation 

for this sector is needed here. 

5 Large Appliance Coatings Group III Issued by EPA in 2007, Control 

Techniques Guidelines for Large Appliance 

Coatings, (EPA 453/R-07-004-2007/09) 

Section 115.450 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.451 states what sources in terms of their threshold values (For example; surface 

coating processes on a property that, when uncontrolled, will emit a combined weight of VOC of 

less than 3.0 pounds per hour and 15 pounds in any consecutive 24-hour period; or emit, when 

uncontrolled, a combined weight of VOC of less than 100 pounds in any consecutive 24-hour 

period) are not subject to these requirements. 

Section 115.453 sets forth what the control requirements for affected source are. For large 

appliance coatings the affected source will need to meet the limits established in Figure: 30 TAC 

§115.453(a)(1)(A) Tables 1 and 2. If a coating meets more than one coating type definition, then 

the coating with the least stringent VOC limit applies. 

Section 115.454 provides for the affected sources in the DFW area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.455 sets forth Test Methods are to determine compliance. Among these methods are 

EPA Test Methods Method 24 for determining VOC limit; ASTM Test Methods D1186-06.01, 

D1200-06.01, D3794-06.01, D2832-69, D1644-75, and D3960-81; and additional test procedures 

described in 40 CFR §60.446 (as amended through October 17, 2000 (65 FR 61761)). Adoption of 

these methods will facilitate compliance determination. 

Section 115.458 establishes monitoring and recordkeeping requirements an affected source in the 

DFW area will need to comply with. The owner or operator shall install and maintain monitors to 

accurately measure and record operational parameters of all required control devices to ensure the 
36 

proper functioning of those devices in accordance with design specifications. Among these 

parameters, as applicable, are: continuous monitoring of the exhaust gas temperature immediately 

downstream of direct-flame incinerators or the gas temperature immediately upstream and 

downstream of any catalyst bed; the total amount of VOC recovered by carbon adsorption or other 

solvent recovery systems during a calendar month; continuous monitoring of carbon adsorption bed 

exhaust; and appropriate operating parameters for capture systems and control devices. For 

recordkeeping the owner or operator will need to maintain records of the testing data or the 

material safety data sheets (MSDS). Furthermore, records must be maintained of the quantity and 

type of each coating and solvent consumed during the specified averaging period if any of the 

coatings, as delivered to the coating application system, exceed the applicable VOC limits. Such 

records must be sufficient to calculate the applicable weighted average of VOC content for all 

coatings. Records must be maintained a minimum of two years and be made available upon request 

to authorized representatives of the executive director, the USEPA, or any local air pollution 

agency with jurisdiction. This provision will assist with compliance determination and 

enforcement of the rule. 

Section 115.459 sets forth the compliance schedule for the DFW area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 

provisions of this sector. The owner or operator of a surface coating process shall comply with 

these requirements on or after March 1, 2013. 

Sections 115.450-459 will provide for controlling VOC emissions from this sector. 

We have previously stated that VOC RACT requirements under the Act are in place for the DFW 

area for the 1-Hour ozone and 8-Hour NAAQS (January 14, 2009 (74 FR 1903)). We are finding 

that these control measures are consistent with those described in EPA’s Control Techniques 

Guidelines for Large Appliance Coatings, (EPA 453/R-07-004-2007/09) recommended controls.

uncontrolled, a combined weight of VOC of less than 100 pounds in any consecutive 24-hour 

period) are not subject to these requirements. 

Section 115.453 sets forth what the control requirements for affected source are. For metal 

furniture the affected source will need to meet the limits established in Figure: 30 TAC 

§115.453(a)(1)(B) Tables 1 and 2. If a coating meets more than one coating type definition, then 

the coating with the least stringent VOC limit applies. If a coating does not meet a specific coating 

type definition, then it can be assumed to be a general-use coating and the VOC limit for general 

coating applies. 

Section 115.454 provides for the affected sources in the DFW area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.455 sets forth Test Methods are to determine compliance. Among these methods are

Techniques Guidelines for Paper, Film, and 

Foil Coatings, (EPA 453/R-07-003-

2007/09) 

Section 115.422(7) sets forth the control requirements specific to the paper, film, and foil coating 

processes in the DFW area so that starting March 1, 2013 the owner or operator of a paper surface 
39 

coating line must implement certain work practices to limit VOC emissions from storage, mixing, 

and handling of cleaning and cleaning-related waste materials. Among these work practices are: 

all VOC-containing cleaning materials must be stored in closed Containers; mixing and storage 

containers used for VOC-containing materials must be kept closed at all times except when 

depositing or removing these materials; spills of VOC-containing cleaning materials must be 

minimized; VOC-containing cleaning materials must be conveyed from one location to another in 

closed containers or pipes; and VOC emissions from the cleaning of storage, mixing, and conveying 

equipment must be minimized. 

Section 115.450 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.451 states what sources in terms of their threshold values (For example; surface

06.01, D3794-06.01, D2832-69, D1644-75, and D3960-81; and additional test procedures 

described in 40 CFR §60.446 (as amended through October 17, 2000 (65 FR 61761)). Adoption of 

these methods will facilitate compliance determination. 

Section 115.458 establishes monitoring and recordkeeping requirements an affected source in the 

DFW area will need to comply with. The owner or operator shall install and maintain monitors to 

accurately measure and record operational parameters of all required control devices to ensure the 

proper functioning of those devices in accordance with design specifications. Among these 

parameters, as applicable, are: continuous monitoring of the exhaust gas temperature immediately 

downstream of direct-flame incinerators or the gas temperature immediately upstream and 

downstream of any catalyst bed; the total amount of VOC recovered by carbon adsorption or other 
42 

solvent recovery systems during a calendar month; continuous monitoring of carbon adsorption bed 

exhaust; and appropriate operating parameters for capture systems and control devices. 

Recordkeeping provisions require the owner or operator will need to maintain records of the testing 

data or the MSDS. Furthermore, records must be maintained of the quantity and type of each 

coating and solvent consumed during the specified averaging period if any of the coatings, as 

delivered to the coating application system, exceed the applicable VOC limits. Such records must 

be sufficient to calculate the applicable weighted average of VOC content for all coatings. Records 

must be maintained a minimum of two years and be made available upon request to authorized 

representatives of the executive director, the USEPA, or any local air pollution agency with 

jurisdiction. This provision will assist with compliance determination and enforcement of the 

rule. 

Section 115.459 sets forth the compliance schedule for the DFW area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 

provisions of this sector. The owner or operator of a surface coating process shall comply with 

these requirements on or after March 1, 2013. 

Sections 115.450-459 will provide for controlling VOC emissions from this sector. 

We have previously stated that VOC RACT requirements under the Act are in place for the DFW 

area for the 1-Hour ozone and 8-Hour NAAQS (January 14, 2009 (74 FR 1903)). We are finding 

that these control measures are consistent with those described in EPA’s Control Techniques 

Guidelines for Auto and Light Duty truck Assembly (EPA 453/R-08-006-2008/09) 

recommended controls. Based on EPA’s May 18, 2006 RACT Q and A document, the 

framework described above, and TCEQ’s certification, a permissible approach per 70 FR 71612, 

November 29, 2008, that its level of control meets RACT we are proposing that the requirements 

established in sections 115.450-459 represent RACT for this sector under the 8-Hour ozone 

NAAQS.

There are no applicable sources of VOC located or operating in the DFW 1997 8-Hour ozone 

nonattainment area for the Fiberglass Boat Manufacturing Materials sector. We are proposing to 

approve a negative declaration for this sector. This approach is permissible within the above 

identified frame work and is in agreement with the 70 FR 71612, November 29, 2008 (Final Rule 

to Implement the 8-Hour Ozone NAAQS). No further evaluation is needed here. 

10 Miscellaneous Industrial 

Adhesives 

Group IV Issued by EPA in 2008, Control 

Techniques Guidelines for Miscellaneous 

Industrial Adhesives, (EPA 453/R-08-005-

2008/09)

Section 115.470 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.471 states what sources (For example; processes using adhesives and adhesive 

primers that are supplied to the manufacturer in containers with a net volume of 16 ounces or less 

or a net weight of 1.0 pound or less; or adhesives or adhesive primers being tested or evaluated in 

any research and development, quality assurance, or analytical laboratory) are not subject to these 

requirements. 

Section 115.473 sets forth what the control requirements for affected source are. These limits are 

based on the daily weighted average of all adhesives or adhesive primers delivered to the 

application system each day. If an adhesive or adhesive primer is used to bond dissimilar substrates 

together, then the applicable substrate category with the least stringent VOC content limit applies. 

The owner or operator of an affected source will need to meet the limits established in Figure: 30 

TAC §115.473(a), Tables 1, 2, and 3. As an alternative, the owner or operator may operate a vapor 

control system capable of achieving an overall control efficiency of 85% of the VOC emissions 

from adhesives and adhesive primers. 

Section 115.474 provides for the affected sources in the DFW area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.475 sets forth Test Methods and testing requirements are to determine compliance. 

Among these methods are EPA Test Method 24, Methods 1 - 4, Method 25, Method 25A or 25B. 

Compliance with the VOC content limits for reactive adhesives must be determined using 40 CFR 
44 

Part 63, Subpart PPPP, Appendix A, (as amended through April 24, 2007 (72 FR 20237)). In 

addition, the owner or operator shall measure the capture efficiency using the applicable 

procedures outlined in 40 CFR §52.741, Subpart O, Appendix B (as amended through October 21, 

1996 (61 FR 54559)). These procedures are: Procedure T-Criteria for and Verification of a 

Permanent or Temporary Total Enclosure; Procedure L - VOC Input; Procedure G.2 - Captured 

VOC Emissions (Dilution Technique); Procedure F.1 - Fugitive VOC Emissions from Temporary 

Enclosures; and Procedure F.2 - Fugitive VOC Emissions from Building Enclosures. 

Section 115.478 establishes monitoring and recordkeeping requirements an affected source in the 

DFW area will need to comply with. The owner or operator shall install and maintain monitors to 

accurately measure and record operational parameters of all required control devices to ensure the 

proper functioning of those devices in accordance with design specifications. Among these 

parameters, as applicable, are: continuous monitoring of the exhaust gas temperature immediately 

downstream of direct-flame incinerators or the gas temperature immediately upstream and 

downstream of any catalyst bed; the total amount of VOC recovered by carbon adsorption or other 

solvent recovery systems during a calendar month; and continuous monitoring of carbon adsorption 

bed exhaust. The owner or operator shall maintain records of the testing data or the MSDS to 

comply with the approved test methods and testing requirements. 

Records must be sufficient to demonstrate continuous compliance with the VOC limits. The 

owner or operator of an application process claiming an exemption must maintain records 

sufficient to demonstrate continuous compliance with the applicable exemption criteria; and must 

maintain records of any testing conducted at an affected facility. Records must be maintained a 

minimum of two years and made available upon request to authorized representatives of TCEQ, 

USEPA, or any local air pollution agency with jurisdiction. This provision will assist with 

compliance determination and enforcement of the rule. 

Section 115.479 sets forth the compliance schedule for the DFW area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 

provisions of this sector. The owner or operator of a surface coating process shall comply with 

these requirements on or after March 1, 2013. 

Sections 115.470-479 will provide for controlling VOC emissions from this sector. 
45 

We have previously stated that VOC RACT requirements under the Act are in place for the DFW 

area for the 1-Hour ozone and 8-Hour NAAQS (January 14, 2009 (74 FR 1903)). We are finding 

that these control measures are consistent with those described in EPA’s Control Techniques 

Guidelines for Miscellaneous Industrial Adhesives, (EPA 453/R-08-005-2008/09) recommended 

controls. Based on EPA’s May 18, 2006 RACT Q and A document, the framework described 

above, and TCEQ’s certification, a permissible approach per 70 FR 71612, November 29, 2008, 

that its level of control meets RACT we are proposing that the requirements established in 

sections 115.470-479 represent RACT for this sector under the 8-Hour ozone NAAQS. 

11 Miscellaneous Metal and Plastic 

Parts Coatings 

Group IV Issued by EPA in 2008, Control 

Techniques Guidelines for Miscellaneous 

Metal and Plastic Parts Coatings, (EPA 

453/R-08-003-2008/09)

Section 115.427(a)(8) specifies that for exemption purposes for miscellaneous metal and plastic 

parts coatings sector in the DFW area a designated on-site maintenance shop is an area at a site 

where used miscellaneous metal parts or products are re-coated on a routine basis. This provision 

will assist with compliance determination. 

Section 115.450 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.451 states what sources in terms of their threshold values (For example; surface 

coating processes on a property that, when uncontrolled, will emit a combined weight of VOC of 

less than 3.0 pounds per hour and 15 pounds in any consecutive 24-hour period; or emit, when 

uncontrolled, a combined weight of VOC of less than 100 pounds in any consecutive 24-hour 

period) are not subject to these requirements. 

Section 115.453 sets forth what the control requirements for affected source are. For 

miscellaneous metal parts and products coatings the affected source will need to meet the limits 

established in Figure: 30 TAC§115.453(a)(1)(C), Tables 1 and 2. For miscellaneous plastic parts 

and products coatings the affected source will need to meet the limits established in Figure: 30 

TAC§115.453(a)(1)(D), Tables 1 and 2. If a coating meets more than one coating type definition, 

then the coating with the least stringent VOC limit applies. If a coating does not meet a specific 
46 

coating type definition, then it can be assumed to be a general-use coating and the VOC limit for 

general coating applies. 

Section 115.454 provides for the affected sources in the DFW area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.455 sets forth Test Methods are to determine compliance. Among these methods are 

EPA Test Methods Method 24 for determining VOC limit; ASTM Test Methods D1186-06.01, 

D1200-06.01, D3794-06.01, D2832-69, D1644-75, and D3960-81; and additional test procedures 

described in 40 CFR §60.446 (as amended through October 17, 2000 (65 FR 61761)). Adoption of 

these methods will facilitate compliance determination. 

Section 115.458 establishes monitoring and recordkeeping requirements an affected source in the 

DFW area will need to comply with. The owner or operator shall install and maintain monitors to 

accurately measure and record operational parameters of all required control devices to ensure the 

proper functioning of those devices in accordance with design specifications. Among these 

parameters, as applicable, are: continuous monitoring of the exhaust gas temperature immediately 

downstream of direct-flame incinerators or the gas temperature immediately upstream and 

downstream of any catalyst bed; the total amount of VOC recovered by carbon adsorption or other 

solvent recovery systems during a calendar month; continuous monitoring of carbon adsorption bed 

exhaust; and appropriate operating parameters for capture systems and control devices. 

Recordkeeping provisions require the owner or operator will need to maintain records of the testing 

data or the MSDS. Furthermore, records must be maintained of the quantity and type of each 

coating and solvent consumed during the specified averaging period if any of the coatings, as 

delivered to the coating application system, exceed the applicable VOC limits. Such records must 

be sufficient to calculate the applicable weighted average of VOC content for all coatings. Records 

must be maintained a minimum of two years and be made available upon request to authorized 

representatives of the executive director, the USEPA, or any local air pollution agency with 

jurisdiction. This provision will assist with compliance determination and enforcement of the 

rule. 

Section 115.459 sets forth the compliance schedule for the DFW area that affected sources will 

need to adhere to the emission specifications; control requirements; and recordkeeping 
47 

provisions of this sector. The owner or operator of a surface coating process shall comply with 

these requirements on or after March 1, 2013. 

Sections 115. 427(a)(8) and 115.451-459 will provide for controlling VOC emissions from this 

sector. 

We have previously stated that VOC RACT requirements under the Act are in place for the DFW 

area for the 1-Hour ozone and 8-Hour NAAQS (January 14, 2009 (74 FR 1903)). We are finding 

that these control measures are consistent with those described in EPA’s Control Techniques 

Guidelines for Miscellaneous Metal and Plastic Parts Coatings, (EPA 453/R-08-003-2008/09) 

recommended controls. Based on EPA’s May 18, 2006 RACT Q and A document, the 

framework described above, and TCEQ’s certification, a permissible approach per 70 FR 71612, 

November 29, 2008, that its level of control meets RACT we are proposing that the requirements 

established in sections 115. 427(a)(8) and 115.451-459 represent RACT for this sector under the 

8-Hour ozone NAAQS. 

Flexographic and Rotogravure Printing Control of Volatile Organic Emissions from 

Existing Stationary Sources – Volume VIII: 

Graphic Arts-Rotogravure and Flexography, 

(EPA-450/2-78-033-78/12)

The Flexographic and Rotogravure Printing sector was not specifically identified as an individual 

sector. This sector is reviewed here, instead. 

Section 115.430 sets forth what sources in the affected area are subject to control requirements, 

and establishes the terms of definitions. 

Section 115.431 states what sources in terms of their threshold values are not subject to these 

requirements. 

Section 115.432 establishes what control requirements are for the affected sources. For example; 

a flexi package printing owner or operator has a daily weighted average limit of 0.16 pounds of 

VOC per pound of coating applied. This requirement can obtained through use of low VOC 

coatings or a combination of coatings and operation of a vapor control system. The vapor control 

system shall achieve at least 80% overall control efficiency by weight. Equation 30 TAC 
48 

115.432(c)(3) shall be used to determine the minimum overall control efficiency. This section will 

provide for VOC control mechanisms. 

Section 115.433 provides for the affected sources in the DFW area with an alternate method of 

control to document and demonstrate continuous compliance. This provision provides for 

operational flexibility to a source. 

Section 115.435 sets forth Test Methods are to determine compliance. Among these methods are 

EPA Test Methods 1 - 4 (40 Code of Federal Regulations (CFR) Part 60, Appendix A) for 

determining flow rates; Method 24 for determining the volatile organic compounds (VOC) content 

and density of printing inks and related coatings; Method 25 for determining total gaseous nonmethane organic emissions as carbon; and Methods 25A or 25B for determining total gaseous 

organic concentrations using flame ionization or non-dispersive infrared analysis. Test Methods 

are also in conformance with EPA guideline series “Procedures for Certifying Quantity of 

Volatile Organic Compounds Emitted by Paint, Ink, and Other Coatings, EPA-450/3-84-019. 

Performance test procedures are described in 40 CFR 60.444. These provisions are federally 

enforceable. 

Section 115.436 establishes monitoring and recordkeeping requirements an affected source in the 

DFW area will need to comply with. Among such elements are: maintaining records of VOC 

contents of all inks, quantity of solvents and inks used, daily records of the quantity of each ink, 

installing and maintaining monitors to continuously measure and record operational parameters 

of any control device installed (exit gas temperature, VOC concentration, and capture efficiency 

protocol), and keeping records at the affected facility for two years. This section will facilitate 

inspection and enforcement of the rule. 

Section 115.439 sets forth the compliance schedule effective March 1, 2013 for the DFW area 

that affected sources will need to adhere to the emission specifications; control requirements; and 

recordkeeping provisions of this sector. 

Sections 115.430-439 will provide for controlling VOC emissions from this sector. 

We have previously stated that VOC and NOx RACT requirements under the Act are in place for 

the DFW area (moderate) for the 8-Hour ozone NAAQS (January 14, 2009 (74 FR 1903) 

rulemaking action). We are finding that these control measures are consistent with those 

described in EPA’s Control Techniques Guidelines for Graphic Arts-Rotogravure and 
49 

Flexography, (EPA-450/2-78-033-78/12) recommended controls. Based on EPA’s May 18, 2006 

RACT Q and A document, the framework described above, and TCEQ’s certification, a 

permissible approach per 70 FR 71612, November 29, 2008, that its level of control meets 

RACT we are proposing that the requirements established in sections 115.430-439 represent 

RACT for this sector for the DFW (serious) for the 8-Hour ozone NAAQS. 

Major Non-CTG sources of VOC in the DFW area: 

As a part of its attainment demonstration plan package, Texas made a list of major point sources 

in the DFW 8-Hour ozone nonattainment area from its emission inventory for sources emitting 

25 or higher tpy of VOC. This listing is not only consistent, but more stringent than Section 

182(c) threshold limit for serious areas (for serious areas, the major source threshold is set at 

emitting or having the potential to emit 50 tpy of VOCs). See Pages 31 through 51, Table F-4, 

Appendix F of the 2010-022-SIP-NR concerning DFW attainment demonstration plan. Also see 

the docket ID No. EPA-R06-OAR-2012-0098 at www. regulations.gov. 

We have shown a sample portion of the Table F-4 entries below for illustration purposes.

Table F-4 lists the registration number, emission source account number, company name, 

standard industrial classification (SIC) code, a brief description of the source, and the reported 

annual emissions in tpy. Most major stationary emission sources in the DFW 8-Hour ozone 

nonattainment area are controlled by source specific state rules that fulfill RACT requirements, 

or are controlled by standards that meet or exceed what would otherwise be considered RACT. 

TCEQ’s certification that its control measures result in the lowest emissions limitation that a 

particular source is capable of meeting through application of control technology that is 

reasonably available, considering technological and economic feasibility, is a permissible 
50 

approach per 70 FR 71612, November 29, 2008. We are have reviewed these controls and their 

requirements, and agree with their approach and determination. We are thus, proposing that its 

level of control for Chapter 117 meets RACT for major Non-CTG sources of VOC in the DFW 

area, and recommend their approval into Texas SIP.

 Part 4: Dallas Fort Worth (DFW) 

B. Oxides of Nitrogen (NOx) 

Moderate: 

The DFW 8-Hour ozone nonattainment area was initially classified as moderate under the 1997 

8-Hour ozone NAAQS. See the January 14, 2009 (74 FR 1903) rulemaking action. 

In addition, the December 3, 2008 (73 FR 73562) rulemaking action approved the 30 TAC 

Chapter 117 revision into the Texas SIP (the 2008 NOx rule approval). 

In the December 3, 2008 (73 FR 73562) rulemaking action, we approved, among other things, 

the Emission Specifications for the Reasonably Available Control Technology (RACT), Section 

117.105, into the Texas SIP. 

The 2008 NOx rule approval also established a compliance schedule to bring major sources in 

the DFW area into compliance under the 8-Hour ozone standard. See Table 12 at 73 FR 73571, 

also depicted below.

The compliance dates for above sources are consistent with the SIP due date set forth in 40 CFR

In addition, to the above source categories, Texas adopted emission limits for process heaters 

larger than 40 MMBtu/hr, lime kilns, incinerators, gas-fired curing ovens, gas-fired ovens and 

heaters, and gas-fired dryers. See section 117.410. Section 117.410 has been approved into the 

Texas SIP. See December 3, 2008 (73 FR 73562). These sources were required to comply with 

the compliance schedule of as soon as practicable but no later than March 1, 2010. The 
53 

compliance date of March 1, 2010 for these source categories is now consistent with the RACT 

implementation SIP due date set forth in 40 CFR 51.912 (a)(3). 

As a part of its attainment demonstration plan, Texas made a list of major point sources in the 

DFW 8-Hour ozone nonattainment area from its emission inventory for sources emitting 50 or 

higher tpy of NOx. This listing is not only consistent, but more stringent than Section 182(b) of 

the Act requirement for moderate areas. Also, see Pages J-15 through J-19, Table J-2, Appendix 

J of that submittal (EPA docket ID No. EPA–R06–OAR–2007–0524, TCEQ Project No. 2006-

013-SIP-NR). The attainment demonstration plan for the DFW area was published on January 

14, 2009 (74 FR 1903). See EPA docket ID No. EPA–R06–OAR–2007–0524 at

controlled by source specific state rules that fulfill RACT requirements, or are controlled by 

standards that meet or exceed what would otherwise be considered RACT. See the preamble to 

the rule project numbers 2006-034-117-EN, and 2006-013-SIP-NR. 

On a separate, yet related matter it is noteworthy to mention that the latest revisions to 30 TAC 

Chapter 117 concerned minor sources and the control requirements of the lean burn engines 

(fired on landfill gas, or bio-gas), and the low temperature drying ovens and curing ovens. Upon 

review, both of these revisions were approved on May 6, 2013 (78 FR 26300). This particular 
54 

action indicated the non-interference of revisions to 30 TAC Chapter 117 with the DFW 

attainment plan. 

TCEQ’s certification that its control measures result in the lowest emissions limitation that a 

particular source is capable of meeting through application of control technology that is 

reasonably available, considering technological and economic feasibility, is a permissible 

approach per 70 FR 71612, November 29, 2008. We are have reviewed these controls and their 

compliance schedule, and agree with their approach and determination. We are thus, proposing 

that its level of control for Chapter 117 meets RACT for a moderate area, and recommend their 

approval into Texas SIP. 

Serious: 

The DFW 8-Hour ozone nonattainment area is currently classified as serious under the 1997 8-

Hour ozone NAAQS, see 75 FR 79302, December 20, 2010. According to EPA’s Final Rule to 

Implement the Eight-Hour Ozone NAAQS (40 Code of Federal Regulations (CFR) §51.912, 

November 29, 2005), a state containing areas classified as moderate nonattainment and above 

must submit a SIP revision demonstrating that its current rules fulfill the RACT requirements for 

all control techniques guidelines (CTG) emission source categories and all non-CTG major 

sources of nitrogen oxides (NOx) and volatile organic compounds (VOC). The major source 

threshold for serious nonattainment areas is 50 tons per year (tpy) or more of either NOx or 

VOC. Appendix F of the SIP submittal 2010-022-SIP-NR provides State’s analysis of the 

sources and the applicable rules to demonstrate that the state is fulfilling the RACT requirements 

for the DFW area. 

With respect to NOx RACT for a serious area, see the revisions to the Texas SIP “Dallas Fort 

Worth Attainment Demonstration State Implementation Plan Revision for the 1997 Eight-Hour 

Ozone Standard (2010-022-SIP-NR)” also available at 

http://www.tceq.texas.gov/airquality/sip/dfw_revisions.html (URL dated May 1, 2014). As a 

part of this plan, TCEQ in its Appendix F titled “Reasonably Available Control Technology 

Analysis” made a list of major point sources in the DFW 8-Hour ozone nonattainment area based 

on its emission inventory for sources emitting 25 or higher tpy of NOx. This listing is not only 

consistent, but more stringent than the Section 182(c) requirement for a serious area. TCEQ 

included sources with emissions limits below the 50 tpy threshold level for a serious area to 
55 

make sure all sources were properly included and none was left out. TCEQ in its Table F-1 lists 

the corresponding State Rules Addressing NOx RACT Requirements and EPA Reference 

Documents. Furthermore, in Table F-3 Texas lists the corresponding State Rules Addressing 

NOx RACT Requirements for Major Emission Sources in the DFW Area. Table F-3 includes 

source’s registration number, emission source account number, company name, SIC code, a brief 

description of the source, and the reported annual emissions in tpy. Most major stationary 

emission sources in the DFW 8-Hour ozone nonattainment area are controlled by source specific 

state rules that fulfill RACT requirements, or are controlled by standards that meet or exceed 

what would otherwise be considered RACT. See pages 20 through 30 of appendix F from the 

2010-022-SIP-NR submittal for a complete listing. We have shown a sample portion of the Table

As a part of the noninterference demonstration and modified failure to attain Texas adopted 

revisions to 30 TAC Chapter 117 that EPA approved into the SIP on May 6, 2013 (78 FR 

26251). For DFW RACT see section 4.2.2 NOx Control Measures of the SIP Revision of the 

TCEQ rule project number 2009-021-SIP-NR submitted to EPA with a letter dated April 6, 2010. 

The EPA’s corresponding docket for this rule project number is EPA-R06-OAR-2010-0337. 

TCEQ’s certification that its control measures result in the lowest emissions limitation that a 

particular source is capable of meeting through application of control technology that is 

reasonably available, considering technological and economic feasibility, is a permissible 
56 

approach per 70 FR 71612, November 29, 2008. We have reviewed these controls and their 

compliance schedule, and agree with their approach and determination. We are thus, proposing 

that its level of control for Chapter 117 meets RACT for a serious area, and recommend their 

approval into the Texas SIP. 

In addition to the foregoing, Texas has some of the most stringent NOx control requirements in 

the country designed for ozone attainment reasons. The NOx controls and reductions 

implemented through Chapter 117 for the DFW ozone nonattainment area encompass both 

RACT and beyond-RACT levels of control. The current EPA-approved Chapter 117 rules fulfill 

RACT requirements for all NOx source categories. These requirements have been approved into 

Texas SIP, and have been federally enforceable for years. For an example list of control 

measures see the following charts/graphs.

Texas Has Some of the Most Stringent Emission Regulations in the U.S. 

A summary of these control strategies. 

The following strategies that have resulted in significant reductions in nitrogen oxides (NOx) 

and volatile organic compounds (VOCs) over the past 10 years: 

 The Mass Emission Cap and Trade program for NOx in the Houston-GalvestonBrazoria (HGB) ozone nonattainment area—reduced the NOx emissions cap for 

thousands of sources by more than 500 tons per day, overall about 80 percent (2002–

08). 

 A comprehensive suite of new rules adopted for the Dallas-Fort Worth (DFW) eighthour ozone nonattainment area requiring NOx reductions from cement kilns, power 

plants, industrial sites, stationary engines used in the oil and gas industry, and many 

other sources (March 2009–March 2010). 

 Rules for enhanced monitoring and testing of flares, cooling towers, and other sources 

of highly reactive volatile organic compounds (HRVOCs) known to cause rapid 

formation of ozone (January 2006). 

 Annual and short-term limits on HRVOC emissions for sources in Harris County 

(January 2007). 

 New requirements for VOC storage tanks in the HGB area to address VOC emissions 

that were found using new technology like gas-imaging cameras that allow the 

operators to observe plumes of VOC emissions that would normally not be visible 

(January 2009). 
57 

Additional State Regulation 

While not required by federal regulations, Texas has also adopted regional control strategies 

that required reductions from certain sources in counties outside the attainment areas. These 

controls help improve air quality in areas like DFW by reducing transport of pollution from 

outside the area. Examples of such regional control strategies include:

 East and Central Texas Utility Rule (Senate Bill 7): Required NOx and SO2 reductions 

from grandfathered power plants in East Texas (2003–05). 

 Regional Cement Kiln Rule: Required NOx reductions from cement kilns in Bexar, 

Comal, Ellis, Hays, and McLennan counties (2003–05). 

 East Texas Combustion Rule: Requires NOx reductions from certain stationary gasfired engines in 33 attainment counties east and southeast of DFW, primarily in the oil 

and gas industry (March 2010). 
58 

 

 Conclusion – DFW Part 3 and Part 4: The EPA had previously approved RACT for VOC and 

NOx into Texas’ SIP under the 1-Hour ozone standard. The EPA has had previously approved 

RACT for VOC sources into Texas’ SIP under the 8-Hour ozone standard, thus finding that these 

control measures result in the lowest emissions limitation that a particular source is capable of 

meeting through application of control technology that is reasonably available, considering 

technological and economic feasibility. 

Based on EPA’s May 18, 2006 RACT Q and A document; the framework identified above; and 

TCEQ’s certification (a permissible approach per 70 FR 71612, November 29, 2008 - Final Rule 

to Implement the 8-Hour Ozone NAAQS) of its RACT, and our above evaluation we are 

proposing to approve the 30 TAC Chapter 115 control requirements as meeting RACT for the 

affected VOC sources, including the newly-issued CTGs, in the DFW 1997 8-Hour ozone 

nonattainment area. 

We are proposing to approve the negative declaration for major source categories that do not 

exist or operate in the DFW 1997 8-Hour ozone nonattainment area. 
59 

We are proposing to approve the 30 TAC Chapter 117 control requirements as meeting RACT 

for a moderate DFW 1997 8-Hour ozone nonattainment area. In addition, we are proposing to 

approve the 30 TAC Chapter 117 control requirements as meeting RACT for a serious DFW 

1997 8-Hour ozone nonattainment area. 

Therefore, by implementing the 30 TAC Chapters 115 and 117 control requirements Texas has 

the 1997 8-Hour RACT in place for all affected VOC and NOx sources in the DFW area. We 

recommend proposing their approval into Texas SIP.
