Therefore, Freeport LNG requests a nine-month extension of time to construct and place its Project inservice by no later than March 21, 2025. This notice establishes a 15-calendar day intervention and comment period deadline. Any person wishing to comment on Freeport LNG’s request for an extension of time may do so. No reply comments or answers will be considered. If you wish to obtain legal status by becoming a party to the proceedings for this request, you should, on or before the comment date stated below, file a motion to intervene in accordance with the requirements of the Commission’s Rules of Practice and Procedure (18 CFR 385.214 or 385.211) and the Regulations under the Natural Gas Act (NGA) (18 CFR 157.10). As a matter of practice, the Commission itself generally acts on requests for extensions of time to complete construction for NGA facilities when such requests are contested before order issuance. For those extension requests that are contested,3 the Commission will aim to issue an order acting on the request within 45 days.4 The Commission will address all arguments relating to whether the applicant has demonstrated there is good cause to grant the extension.5 The Commission will not consider arguments that re-litigate the issuance of the certificate order, including whether the Commission properly found the project to be in the public convenience and necessity and whether the Commission’s environmental analysis for the certificate complied with the National Environmental Policy Act (NEPA).6 At the time a pipeline requests an extension of time, orders on certificates of public convenience and necessity are final and the Commission 2 Freeport LNG states that Linde’s progress has been affected by the market availability of certain equipment, having to make engineering changes based on newly received data, and Hurricane Beryl. Additionally, Linde has indicated that it anticipates placing the non-jurisdictional facilities in-service by the end of 2024. 3 Contested proceedings are those where an intervenor disputes any material issue of the filing. 18 CFR 385.2201(c)(1). 4 Algonquin Gas Transmission, LLC, 170 FERC ¶ 61,144, at P 40 (2020). 5 Id. at P 40. 6 Similarly, the Commission will not re-litigate the issuance of an NGA section 3 authorization, including whether a proposed project is not inconsistent with the public interest and whether the Commission’s environmental analysis for the permit order complied with NEPA.

II. Information Available for Public Comment

    The EPA is requesting comment on one updated chapter of the EPA Air 
Pollution Control Cost Manual. The Control Cost Manual contains 
individual chapters on control measures, including data and equations 
to aid users in estimating capital costs for installation and annual 
costs for operation and maintenance of these measures, and data 
concerning the percentage of pollutant emissions that control measures 
can reduce. The Control Cost Manual is used by the EPA for estimating 
the impacts of rulemakings and serves as a basis for sources to 
estimate costs of controls that are Best Available Control Technology 
(BACT) under the New Source Review Program, the Regional Haze Program, 
Reasonably Achievable Control Technology (RACT) for State 
Implementation Plans (SIPs) and for other programs.
    The one updated Control Cost Manual chapter is: Chapter 1, Section 
6, ``Fabric Filters.'' This revised Control Cost Manual chapter can be 
found in the docket for the Control Cost Manual update (Docket ID No.

2003.
    The Consolidated Appropriations Act of 2014 requested that the EPA 
begin development of a seventh edition of the Control Cost Manual. The 
EPA has met with state, local, and Tribal officials to discuss plans 
for the Control Cost Manual update as called for under the Consolidated 
Appropriations Act of 2014. The EPA has met with other groups as well 
at their request. The EPA has updated the selective non-catalytic 
reduction (SNCR) and selective catalytic reduction (SCR) chapters, the 
first two chapters (Chapter 1, Section 4; Chapter 2, Section 4, 
respectively) completed for the seventh edition of the Control Cost 
Manual and made them available to the public in May 2016 (81 FR 38702, 
June 14, 2016) and also updated these chapters again in May 2019. In 
addition, the EPA has updated the Refrigerated Condensers (Chapter 1, 
Section 3 and Section 3.1) and Incinerators (Chapter 2, Section 3, 
Section 3.2, now Incinerators/Oxidizers) chapters in November 2017, the 
Cost Estimation: Concepts and Methodology chapter (Chapter 2, Section 
1) as of November 2017, the Carbon Adsorbers (Chapter 1, Section 3, 
Section 3.1) and Flares (Chapter 1, Section 3, Section 3.2) chapters in 
October 2018, and the Gas Absorbers (now (Wet and Dry Scrubbers for 
Acid Gas, Chapter 1, Section 5) chapter in May 2021.
    To help focus review of the Fabric Filters chapter, we offer the 
following list of questions that the EPA is particularly interested in 
addressing in the updated chapter. Regardless of the topics that are

mercury? Please provide data, if possible, to address inaccuracies.
    (6) Are the capital cost correlations, factors, and equations for 
fabric filters applied to various types of emissions sources and 
industries accurate and up to date? Are the annual costs (such as 
operating and maintenance costs) for fabric filters applied to various 
types of emissions sources and industries accurate and up-to-date? If 
not, how should they be revised? Please provide data, if possible, to 
address inaccuracies.
    (7) This revised Control Cost Manual chapter lists test methods
