SUPPLEMENTARY INFORMATION:
Throughout this document, we, us and our refer to the EPA.

MCAQDs RACT SIP provides the Countys demonstration that the applicable SIP for the MCAQD satisfies CAA section 182 RACT requirements for the 2008 8-hour ozone NAAQS. This conclusion is based on the Countys analysis of SIP-approved requirements that apply to the following: 1 Source categories for which the EPA has issued a Control Techniques Guidelines CTG
document, and 2 major non-CTG
stationary sources of Volatile Organic Compounds VOCs or oxides of nitrogen NOX.
With respect to CTG source categories, MCAQD determined that it had sources subject to the CTGs covering solvent metal cleaning, industrial cleaning solvents, miscellaneous metal and plastic parts coating, can coating, fabric coating, film and foil coating, rotogravure and flexography, lithographic printing and letter press printing, wood furniture manufacturing operations, storage of petroleum liquids, tank truck gasoline loading terminals, bulk gasoline plants, gasoline tank trucks and vapor collection systems, and gasoline service stations. MCAQD submitted for SIP
approval six rules to implement RACT
for these CTG categories: Rules 336, 342, 350, 351, 352, and 353.
On February 26, 2020 85 FR 10986, the EPA conditionally approved Rules 350, 351, 352, and 353 into the SIP, and also conditionally approved the associated CTG source categories for the MCAQD 2016 RACT SIP: Control of Volatile Organic Emissions from Storage of Petroleum Liquids in Fixed-Roof Tanks EPA450/277036, Control

MCAQD has committed to correct the EPAs identified deficiencies, and ADEQ has committed to submit the updated rules within one year of the EPAs final conditional approval. If MCAQD
corrects the identified deficiencies and the EPA approves the updated rules, MCAQD will have met its RACT
obligation for these rules, and the associated CTGs. We are not acting on rules 350, 351, 352, and 353, or the associated CTG categories in the MCAQDs 2016 RACT SIP in this action.
On August 27, 2019 84 FR 44701, the EPA approved Rule 342 into the SIP, finding that the rule met current RACT.
This rulemaking also approved Rule 337, which had been submitted earlier and was not part of the 2016 RACT SIP
submittal. Although we approved Rules 337 and 342, and found that they established RACT level controls, we did not in that action approve the 2016
RACT SIP for the associated CTG source categories. On September 18, 2020 85
