Significant New Use Rules on Certain 
Chemical Substances; Withdrawal 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Withdrawal of direct final rule. 
SUMMARY : EPA is withdrawing 
significant new use rules (SNURs) promulgated under the Toxic Substances Control Act (TSCA) for 145 chemical substances, which were the subjects of premanufacture notices (PMNs). EPA published these SNURs using direct final rulemaking procedures, which requires EPA to take certain actions if an adverse comment is received. EPA received adverse comments regarding the SNURs identified in this document. Therefore, the Agency is withdrawing the direct final rule SNURs identified in this document, as required under the direct final rulemaking procedures. 
DATES : The direct final rule published at 
83 FR 37702 on August 1, 2018, is withdrawn effective September 26, 2018. 
ADDRESSES : The docket for this action, 
identified by docket identification (ID) number EPA–HQ–OPPT–2017–0366, is available at http://www.regulations.gov or at the Office of Pollution Prevention and Toxics Docket (OPPT Docket), Environmental Protection Agency Docket Center (EPA/DC), West William Jefferson Clinton Bldg., Rm. 3334, 1301 Constitution Ave. NW, Washington, DC.

FOR 
FURTHER INFORMATION CONTACT . II. What direct final SNURs are being 
withdrawn? 
In the Federal Register of August 1, 
2018 (83 FR 37702), EPA issued direct final SNURs for all 145 chemical substances that are identified in this document. Because the Agency received adverse comments that relate to each of the 145 chemical substances, EPA is withdrawing the direct final SNURS issued for these 145 chemical substances. In addition to the Direct Final SNURs, elsewhere in the same issue of the Federal Register of August 1, 2018, EPA issued proposed SNURs covering these 145 chemical substances (83 FR 37455) (FRL–9981–16). EPA will address all adverse public comments in a subsequent final rule, based on the proposed rule. 
III. Good Cause Finding 
EPA determined that this document is 
not subject to the 30-day delay of 
effective date generally required by the Administrative Procedure Act (APA) (5 U.S.C. 553(d)) because of the time limitations for publication in the Federal Register. This document must publish on or before the effective date of the direct final rule containing the direct final SNURs being withdrawn. 
IV. Statutory and Executive Order 
Reviews 
This action withdraws regulatory 
requirements that have not gone into effect and which contain no new or amended requirements. As such, the Agency has determined that this action will not have any adverse impacts, economic or otherwise. The statutory and Executive Order review requirements applicable to the direct final rule were discussed in the August 1, 2018 Federal Register. Those review requirements do not apply to this action because it is a withdrawal and does not contain any new or amended requirements. 
V. Congressional Review Act (CRA) 
Pursuant to the Congressional Review 
Act (5 U.S.C. 801 et seq.), EPA will 
submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. This action is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2). Section 808 of the CRA allows the 
issuing agency to make a rule effective sooner than otherwise provided by CRA if the agency makes a good cause finding that notice and public procedure is impracticable, unnecessary, or contrary to the public interest. As

Tennessee’s June 25, 2008, SIP revision in a 
separate rulemaking. 2In the proposed rule at 83 FR 10814 (March 13,

Organic Compounds 
AGENCY : Environmental Protection

The revision amends the definition of ‘‘volatile organic compounds’’ (VOC) to be consistent with state and Federal regulations. The portion of the SIP revision that EPA is approving is consistent with the requirements of the Clean Air Act (CAA or Act). EPA will act on the other portions of the June 25, 2008, submittal in a separate action. 
DATES : This rule will be effective 
October 26, 2018.

SUPPLEMENTARY INFORMATION : 
I. Background 
On March 13, 2018 (83 FR 10813), 
EPA proposed to approve into the Tennessee SIP the portion of the revisions to the Chattanooga-Hamilton County air quality rules in Chapter 4 of Part II, Section 4–2, submitted by TDEC on behalf of Chattanooga-Hamilton County on June 25, 2008.
1The 
definition of ‘‘Volatile Organic Compounds’’ in Chapter 4 of Part II, Section 4–2, ‘‘Definitions’’ is amended to be consistent with the Federal definition of VOC at 40 CFR 51.100(s). In summary, the amendments add several compounds to the list of negligibly reactive compounds, make minor changes to paragraph 3 (related to preconditions to excluding compounds as VOCs), and adds paragraph 4 (related to test methods used for purposes of enforcement) and paragraph 5 (related to recordkeeping and reporting requirements for t-butyl acetate). The details of the Tennessee submissions and the rationale for EPA’s action are explained in the proposed rulemaking. Comments on the proposed rulemaking were due on or before April 13, 2018. EPA did not receive any adverse comments on the proposed action. 
II. Incorporation by Reference 
In this rule, EPA is finalizing 
regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 51.5, EPA is finalizing the incorporation by reference of Chattanooga-Hamilton County’s air quality rules in Chapter 4 of Part II, Section 4–2, ‘‘Definitions’’ effective June 11, 2008,
2to be consistent 
with the definition of VOC at 51.100. EPA has made, and will continue to make, these materials generally available through www.regulations.gov and at the EPA Region 4 Office (please contact the person identified in the 
FOR 
FURTHER INFORMATION CONTACT section of 
this preamble for more information). Therefore, these materials have been approved by EPA for inclusion in the SIP, have been incorporated by reference by EPA into that plan, are fully federally-enforceable under 
sections 110 and 113 of the CAA as of the effective date of the final rulemaking of EPA’s approval, and will be incorporated by reference in the next update to the SIP compilation.

III. Final Action 
EPA is taking final action to approve 
a portion of a revision to the Chattanooga-Hamilton County portion of the Tennessee SIP which amends the definition of ‘‘Volatile Organic Compounds’’ in the Chattanooga Code, Chapter 4 of Part II, Section 4–2. This SIP revision also amends paragraph 3 and adds paragraphs 4 and 5 to the Chattanooga Code, Chapter 4 of Part II, Section 4–2 definition of VOC. EPA has evaluated the relevant portions of Tennessee’s June 25, 2008, SIP revision and has determined that it meets the applicable requirements of the CAA and EPA regulations. 
IV. Statutory and Executive Order 
Reviews 
Under the CAA, the Administrator is 
required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. See 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet the criteria of
