Federal Register / Vol. 86, No. 34 / Tuesday, February 23, 2021 / Proposed Rules 10909 

procedures for changes that do not 

require a Non-Title V Permit from Rule 

220, Section 404.3.e.; (7) the 

requirements for holding a public 

hearing from Rule 241, Section 310; and 

(8) the source obligation provision from 

Rule 241, Section 315. These 

requirements were moved to other rules 

or are already addressed in existing 

rules. The EPA finds these revisions 

acceptable. 

Other General Rule Revisions 

The MCAQD made several other 

minor wording and administrative 

changes to Rules 100, 200, 210, 220, 

240, and 241. As discussed further in 

our TSD, these rule revisions are 

acceptable. 

We are proposing to fully approve 

Rules 100, 200, 210, 220, 230, 240 and 

241 as part of the MCAQD’s general and 

NSR permitting programs because we 

have determined that these rules satisfy 

the substantive statutory and regulatory 

requirements of section 110(a)(2)(C) of 

the Act, parts C and D of title I of the 

Act, 40 CFR 51.160–51.166, and 40 CFR 

51.307. Our TSD for this rulemaking 

contains a more detailed evaluation. 

III. Proposed Action and Public 

Comment 

As authorized in section 110(k)(3) of 

the Act, the EPA proposes to fully 

approve the MCAQD Rules 100, 200, 

210, 220, 230, 240, and 241, because 

they fulfill all relevant requirements. 

We are accepting comments from the 

public on this proposal until March 25, 

2021. If we finalize this action as 

proposed, our action would be codified 

through revisions to 40 CFR 52.120 

(Identification of plan). 

IV. Incorporation by Reference 

In this rule, the EPA is proposing to 

include in a final EPA rule regulatory 

text that includes incorporation by 

reference. In accordance with 

requirements of 1 CFR 51.5, the EPA is 

proposing to incorporate by reference 

the MCAQD rules listed in Table 1 of 

this notice. The EPA has made, and will 

continue to make, these documents 

generally available electronically 

through www.regulations.gov and at the 

EPA Region IX Office (see the FOR

FURTHER INFORMATION CONTACT section of 

this preamble for more information). 

V. Statutory and Executive Order 

Reviews 

Under the Clean Air Act, the 

Administrator is required to approve a 

SIP submission that complies with the 

provisions of the Act and applicable 

federal regulations. 42 U.S.C. 7410(k); 

40 CFR 52.02(a). Thus, in reviewing SIP 

submissions, the EPA’s role is to 

approve state choices, provided that 

they meet the applicable criteria of the 

Clean Air Act. Accordingly, this action 

merely approves state law as meeting 

federal requirements and does not 

impose additional requirements beyond 

those imposed by state law. For that 

reason, this action: 

• Is not a significant regulatory action 

subject to review by the Office of 

Management and Budget under 

Executive Orders 12866 (58 FR 51735, 

October 4, 1993) and 13563 (76 FR 3821, 

January 21, 2011); 

• Does not impose an information 

collection burden under the provisions 

of the Paperwork Reduction Act (44 

U.S.C. 3501 et seq.); 

• Is certified as not having a 

significant economic impact on a 

substantial number of small entities 

under the Regulatory Flexibility Act (5 

U.S.C. 601 et seq.); 

• Does not contain any unfunded 

mandate or significantly or uniquely 

affect small governments, as described 

in the Unfunded Mandates Reform Act 

of 1995 (Pub. L. 104–4); 

• Does not have federalism 

implications as specified in Executive 

Order 13132 (64 FR 43255, August 10, 

1999); 

List of Subjects in 40 CFR Part 52

Hazardous Waste Management 

System; Identification and Listing of 

Hazardous Waste 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed amendment. 

SUMMARY: The Environmental Protection 

Agency (EPA) is proposing to modify an 

exclusion from the lists of hazardous 

waste previously granted to American 

Chrome and Chemical (Petitioner), in 

Corpus Christi, Texas. This action 

responds to a petition for amendment to 

exclude (or ‘‘delist’’) up to 1,450 cubic 

yards per year of K006 chromic oxide 

solids from the list of federal hazardous 

wastes when disposed of in an on-site 

surface impoundment in lieu of disposal 

in a Subtitle D Landfill. The Agency is 

proposing to grant the petition based on 

an evaluation of waste-specific 

information provided by the petitioner. 

DATES: Comments on this proposed 

amendment must be received by March 

25, 2021. 

ADDRESSES: Submit your comments by
