Federal Register / Vol. 86, No. 4 / Thursday, January 7, 2021 / Rules and Regulations 453/R07005, Control Techniques Guidelines for Large Appliance Coatings EPA453/R07004, Control Techniques Guidelines for Miscellaneous Metal and Plastic Parts Coatings EPA453/R08003, and Control Techniques Guidelines For Paper, Film, and Foil Coatings EPA
453/R07003. MCAQD has committed to correct the EPAs identified deficiencies, and ADEQ has committed to submit the updated rule within one year of the EPAs final conditional approval. If MCAQD corrects the identified deficiencies and the EPA
approves the updated rule, the County will have met its RACT obligation for this rule, and the associated CTGs.
On September 18, 2020 85 FR 58310, we proposed to approve negative declarations, including negative declarations for some of the source categories covered by Rule 336.
Specifically, of eight CTG source categories addressed by Rule 336 as listed in the prior paragraph, our September proposal proposed to approve negative declarations for five of them: Control of Volatile Organic Emissions from Existing Stationary SourcesVolume III: Surface Coating of Metal Furniture EPA450/277032, Control of Volatile Organic Emissions from Existing Stationary Sources Volume V: Surface Coating of Large Appliances EPA450/277034, Control Techniques Guidelines for Metal Furniture Coatings EPA453/R
07005, Control Techniques Guidelines for Large Appliance Coatings EPA453/R07004, and Control Techniques Guidelines For Paper, Film, and Foil Coatings EPA
453/R07003. In addition, it proposed approval of negative declarations for the coils, paper, automobile and light-duty truck portions of the CTG Control of Volatile Organic Emissions from Existing Stationary Sources Volume II: Surface Coating of Cans, Coils, Paper, Fabrics, Automobiles, and Light-Duty Trucks EPA450/277008. In the same notice, the EPA also proposed to disapprove negative declarations for the Aerospace Coating and Industrial Adhesives source categories, because there are applicable sources in the Maricopa County portion of the Phoenix-Mesa ozone nonattainment area.
With respect to major non-CTG
stationary sources of Volatile Organic Compounds VOCs or oxides of nitrogen NOX, MCAQD determined it had RACT rules covering these sources.
On September 18, 2020 85 FR 58310, the EPA proposed to approve the Countys RACT determination that it has RACT rules covering major non-

CTG sources of VOC and proposed to disapprove the RACT determination that it has RACT rules covering major sources of NOX.
The proposed actions and associated technical support documents contain more information on the basis for this rulemaking and on our evaluation of the submittal.
II. EPA Action The EPAs proposed actions provided 30-day public comment periods. During the comment periods for the two proposed actions, we received no comments. Therefore, as authorized in section 110k4 of the Act, the EPA is conditionally approving into the Arizona SIP, Rule 336 and MCAQDs RACT Demonstration for the 2008 8-hr ozone NAAQS with respect to the following Control Techniques Guidelines CTGs, as described in our proposal:
1. Control of Volatile Organic Emissions from Existing Stationary SourcesVolume II: Surface Coating of Cans, Coils, Paper, Fabrics, Automobiles, and Light-Duty Trucks EPA450/277008, May 1977, cans and fabrics portions only.1
2. Control of Volatile Organic Emissions from Existing Stationary SourcesVolume VI: Surface Coating of Miscellaneous Metal Parts and Products, EPA450/27815, June 1978.
3. Control Techniques Guidelines for Miscellaneous Metal and Plastic Parts Coatings, EPA453/R08003, September 2008.2
If the MCAQD and the ADEQ submit the required rule revisions to Rule 336
by the specified deadline, and the EPA
approves the submission, then the identified deficiencies will be cured.
However, if MCAQD, through the ADEQ, fails to submit these revisions to Rule 336 within the required timeframe, the conditional approval will be treated as a disapproval for Rule 336 and the RACT demonstration for the three CTG
categories listed above.
1 Note that in this action the EPA is finalizing approval of negative declarations for the other categories covered by this CTG: Surface coating of coils, paper, automobiles, and light-duty trucks.
2 Our January 28, 2020 proposal also noted that the deficiencies in Rule 336 were not consistent with the 2007 CTGs for Metal Furniture and Large Appliance Coatings 85 FR at 4930. However, our September 18, 2020 proposal proposed to approve negative declarations for these two source categories. This final action approves these negative declarations. Therefore, the RACT SIP is fully approved with respect to these CTG source categories, and they are not included within the scope of the conditional approval of the RACT
demonstration for CTG source categories associated with Rule 336.

Also, as authorized in sections 110k3 and 301a of the Act, the EPA
is finalizing a partial approval and partial disapproval of the remainder of the RACT SIP and associated negative declarations, as proposed.
We are finalizing a partial disapproval with respect to the portions of the RACT
SIP addressing RACT for major sources of NOX, and CTG source categories for Aerospace Coating and Industrial Adhesives National Emission Standards for Hazardous Air Pollutants for Source Categories: Aerospace Manufacturing and Rework 59 FR
29216, Control of Volatile Organic Compound Emissions from Coating Operations at Aerospace Manufacturing and Rework Operations EPA453/R
97004, and Control Techniques Guidelines for Miscellaneous Industrial Adhesives EPA453/R08005. As a result of the final partial disapproval, offset sanctions will be imposed unless the EPA approves a subsequent SIP
revision that corrects the identified deficiencies within 18 months of the effective date of this action. Highway sanctions will be imposed unless the EPA approves a subsequent SIP revision that corrects the rule deficiencies within 24 months of the effective date of this action. These sanctions will be imposed under section 179 of the CAA and 40
CFR 52.31. Additionally, section 110c requires the EPA to promulgate a federal implementation plan within 24 months unless we approve subsequent SIP
revisions that correct the deficiencies.
The EPA is finalizing a partial approval of the RACT SIP with respect to all remaining source categories, as proposed. This includes approval of the Countys negative declarations, with the exception of the three disapproved negative declarations, and the Countys RACT certifications for the following CTG source categories: Control of Volatile Organic Emissions from Solvent Metal Cleaning EPA450/277022, Control Techniques Guidelines:
Industrial Cleaning Solvents EPA
