2018-11-28; vol. 83 # 229 - Wednesday, November 28, 2018
83 FR 61127 - Air Quality: Revision to the Regulatory Definition of Volatile Organic Compounds—Exclusion of cis-1,1,1,4,4,4-hexafluorobut-2-ene (HFO-1336mzz-Z)
FR Doc. 2018-25891
EPA-HQ-OAR-2017-0175
FRL-9987-02-OAR
On May 1, 2018, the U.S. Environmental Protection Agency (EPA) published a proposed rule seeking comments in response to a petition requesting the revision of the EPA&apos;s regulatory definition of volatile organic compounds (VOC) to exempt cis -1,1,1,4,4,4-hexafluorobut-2-ene (also known as HFO-1336mzz-Z; CAS number 692-49-9). The EPA is now taking final action to revise the regulatory definition of VOC under the Clean Air Act (CAA). This final action adds HFO-1336mzz-Z to the list of compounds excluded from the regulatory definition of VOC on the basis that this compound makes a negligible contribution to tropospheric ozone (O 3 ) formation.

FRL-9986-42-OAR
83 FR 56713 - Testing Regulations for Air Emission Sources
FR Doc. 2018-24747
The final rule is effective on January 14, 2019. The incorporation by reference materials listed in the rule are approved by the Director of the Federal Register as of January 14, 2019.
This action amends certain existing testing regulations to reflect corrections, updates, and the addition of alternative equipment and methods for source testing of emissions. These revisions will improve the quality of data and provide flexibility in the use of approved alternative procedures. The revisions do not impose any new substantive requirements on source owners or operators.
2018-09-27; vol. 83 # 188 - Thursday, September 27, 2018
83 FR 48751 - Emissions Monitoring Provisions in State Implementation Plans Required Under the NO X SIP Call
FR Doc. 2018-20858
RIN 2060-AU08
EPA-HQ-OAR-2018-0595
FRL-9984-19-OAR
Comments must be received on or before October 29, 2018. To request a public hearing, please contact the person listed in the FOR FURTHER INFORMATION CONTACT section by October 4, 2018. EPA does not plan to conduct a public hearing unless requested.
The Environmental Protection Agency (EPA) is proposing to update the regulations that were originally promulgated in 1998 to implement the NO X SIP Call. In place of the current requirement for states to include provisions in their state implementation plans (SIPs) under which certain emissions sources must monitor their mass emissions of nitrogen oxides (NO X ) according to 40 CFR part 75, the proposed amendments would allow states to include alternate forms of monitoring requirements in their SIPs. The amendments would also rescind the findings of interstate pollution transport obligations with respect to the 1997 8-hour ozone national ambient air quality standards (NAAQS) under the NO X SIP Call that have been stayed by EPA since 2000. Other revisions would remove additional obsolete provisions and clarify the remaining regulations but would not substantively alter any current regulatory requirements.

83 FR 45588 - Emission Guidelines for Greenhouse Gas Emissions From Existing Electric Utility Generating Units; Revisions to Emission Guideline Implementing Regulations; Revisions to New Source Review Program
FR Doc. 2018-19505
Public Hearing: The EPA will hold a public hearing on October 1, 2018, in Chicago, Illinois. Please refer to the SUPPLEMENTARY INFORMATION section for additional information on the public hearing. Comments: The EPA must receive comments on this proposed action no later than October 31, 2018.
83 FR 44746 - Emission Guidelines for Greenhouse Gas Emissions From Existing Electric Utility Generating Units; Revisions to Emission Guideline Implementing Regulations; Revisions to New Source Review Program
FR Doc. 2018-18755
FRL-9982-89-OAR
Comments. Comments must be received on or before October 30, 2018. Under the Paperwork Reduction Act (PRA), comments on the information collection provisions are best assured of consideration if the Office of Management and Budget (OMB) receives a copy of your comments on or before October 1, 2018. Public hearing: EPA is planning to hold at least one public hearing in response to this proposed action. Information about the hearing, including location, date, and time, along with instructions on how to register to speak at the hearing, will be published in a second Federal Register document.
The Environmental Protection Agency (EPA) is proposing three distinct actions, including Emission Guidelines for Greenhouse Gas Emissions from Existing Electric Utility Generating Units (EGUs). First, EPA is proposing to replace the Clean Power Plan (CPP) with revised emissions guidelines (the Affordable Clean Energy (ACE) rule) that inform the development, submittal, and implementation of state plans to reduce greenhouse gas (GHG) emission from certain EGUs. In the proposed emissions guidelines, consistent with the interpretation described in the proposed repeal of the CPP, the Agency is proposing to determine that heat rate improvement (HRI) measures are the best system of emission reduction (BSER) for existing coal-fired EGUs. Second, EPA is proposing new regulations that provide direction to both EPA and the states on the implementation of emission guidelines. The new proposed implementing regulations would apply to this action and any future emission guideline issued under section 111(d) of the Clean Air Act (CAA). Third, the Agency is proposing revisions to the New Source Review (NSR) program that will help prevent NSR from being a barrier to the implementation of efficiency projects at EGUs.
83 FR 19026 - Air Quality: Revision to the Regulatory Definition of Volatile Organic Compounds—Exclusion of cis-1,1,1,4,4,4-hexafluorobut-2-ene (HFO-1336mzz-Z)

EPA-HQ-OAR-2016-0456
FRL-9966-75-OAR
Comments. Comments must be received on or before November 7, 2017. Public Hearing. If a public hearing is requested by September 18, 2017, then we will hold a public hearing on October 10, 2017 at the location described in the ADDRESSES section. The last day to pre-register in advance to speak at the public hearing will be October 6, 2017.
In this action, the Environmental Protection Agency (EPA) proposes editorial and technical revisions to the EPA&apos;s Method 202—Dry Impinger Method for Determining Condensable Particulate Emissions from Stationary Sources to improve the consistency in results achieved across the testing community.
FR Doc. 2016-31747
RIN 2060-AS54
FRL-9956-23-OAR
This rule is effective February 16, 2017. For all regulatory applications covered under the Guideline, except for transportation conformity, the changes to the appendix A preferred models and revisions to the requirements and recommendations of the Guideline must be integrated into the regulatory processes of respective reviewing authorities and followed by applicants by no later than January 17, 2018. During the 1-year period following promulgation, protocols for modeling analyses based on the 2005 version of the Guideline, which are submitted in a timely manner, may be approved at the discretion of the appropriate reviewing authority. This final rule also starts a 3-year transition period that ends on January 17, 2020 for transportation conformity purposes. Any refined analyses that are started before the end of this 3-year period, with a preferred appendix A model based on the 2005 version of the Guideline, can be completed after the end of the transition period, similar to implementation of the transportation conformity grace period for new emissions models. See the discussion in section IV.A.4 of this preamble for details on how this transition period will be implemented. All applicants are encouraged to consult with their respective reviewing authority as soon as possible to assure acceptance of their modeling protocols and/or modeling demonstration during either of these periods.
In this action, the Environmental Protection Agency (EPA) promulgates revisions to the Guideline on Air Quality Models (“ Guideline” ). The Guideline provides EPA&apos;s preferred models and other recommended techniques, as well as guidance for their use in estimating ambient concentrations of air pollutants. It is incorporated into the EPA&apos;s regulations, satisfying a requirement under the Clean Air Act (CAA) for the EPA to specify with reasonable particularity models to be used in the Prevention of Significant Deterioration (PSD) program. This action includes enhancements to the formulation and application of the EPA&apos;s preferred near-field dispersion modeling system, AERMOD (American Meteorological Society (AMS)/EPA Regulatory Model), and the incorporation of a tiered demonstration approach to address the secondary chemical formation of ozone and fine particulate matter (PM 2.5 ) associated with precursor emissions from single sources. The EPA is changing the preferred status of and removing several air quality models from appendix A of the Guideline. The EPA is also making various editorial changes to update and reorganize information throughout the Guideline to streamline the compliance assessment process.

FR Doc. 2016-24911
RIN 2060-AS59
EPA-HQ-OAR-2015-0090
FRL-9954-10-OAR
The effective date of this final rule is November 17, 2016.
40 CFR Parts 51, 52, 55, 70, 71 and 124
The U.S. Environmental Protection Agency (EPA) is revising the public notice rule provisions for the New Source Review (NSR), title V and Outer Continental Shelf (OCS) permit programs of the Clean Air Act (CAA or Act) and corresponding onshore area (COA) determinations for implementation of the OCS air quality regulations. This final rule removes the mandatory requirement to provide public notice of a draft air permit (as well as certain other program actions) through publication in a newspaper. Instead, this final rule requires electronic notice (e-notice) for EPA actions (and actions by permitting authorities implementing the federal permitting rules) and allows for e-notice as an option for actions by permitting authorities implementing EPA-approved programs. When e-notice is provided, the final rule requires, at a minimum, electronic access (e-access) to the draft permit. However, this final rule does not preclude a permitting authority from supplementing e-notice with newspaper notice and/or additional means of notification to the public. The EPA anticipates that e-notice, which is already being practiced by many permitting authorities, will enable permitting authorities to communicate permitting and other affected actions to the public more quickly and efficiently and will provide cost savings over newspaper publication. The EPA further anticipates that e-access will expand access to permit-related documents.
81 FR 50330 - Air Quality: Revision to the Regulatory Definition of Volatile Organic Compounds—Exclusion of 1,1,2,2-Tetrafluoro-1-(2,2,2-trifluoroethoxy) Ethane (HFE-347pcf2)
FR Doc. 2016-17789
RIN 2060-AR94
FRL-9949-77-OAR
This rule is effective on September 30, 2016 without further notice, unless the EPA receives adverse comment by August 31, 2016. If the EPA receives adverse comment, we will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect.
The Environmental Protection Agency (EPA) is taking direct final action to revise the regulatory definition of volatile organic compounds (VOC) under the Clean Air Act (CAA). This direct final action adds 1,1,2,2-Tetrafluoro-1-(2,2,2-trifluoroethoxy) ethane (also known as HFE-347pcf2; CAS number 406-78-0) to the list of compounds excluded from the regulatory definition of VOC on the basis that this compound makes a negligible contribution to tropospheric ozone (O 3 ) formation.

81 FR 43180 - Protection of Visibility: Amendments to Requirements for State Plans
FR Doc. 2016-15493
FRL-9948-53-OAR
The public comment period for the proposed ruled published in the Federal Register on May 4, 2016, (81 FR 26942) is being extended. Written comments must be received on or before August 10, 2016.
40 CFR Part 51 and 52
On May 4, 2016, the Environmental Protection Agency (EPA) proposed a rule titled, “Protection of Visibility: Amendments to Requirements for State Plans.” The EPA is extending the comment period on the proposed rule that was scheduled to close on July 5, 2016. The EPA has received requests for additional time to review and comment on the proposed rule revisions.
81 FR 35622 - Source Determination for Certain Emission Units in the Oil and Natural Gas Sector
FR Doc. 2016-11968
FRL-9946-55-OAR
The U.S. Environmental Protection Agency (EPA) is finalizing a revision to regulations applicable to permitting of stationary sources of air pollution under the New Source Review (NSR) and title V programs in the Clean Air Act (CAA or Act). For sources in the oil and natural gas sector, this rule clarifies the meaning of the term “adjacent” that is used to determine the scope of a “stationary source” for purposes of the Prevention of Significant Deterioration (PSD) and Nonattainment NSR (NNSR) preconstruction permitting programs and the scope of a “major source” in the title V operating permit program in the onshore oil and natural gas sector. The revised definitions are based on the proximity of emitting activities and consideration of whether the activities share equipment. We believe that this clarification will provide greater certainty for the regulated community and for permitting authorities, and will result in more consistent determinations of the scope of a source in this sector. The EPA is adopting this revised definition in the regulations that apply to permits issued by the EPA and states to which the EPA has delegated federal authority to administer these programs. Other state and local permitting authorities with EPA-approved programs may also revise their permit programs to adopt this definition, but are not required to do so.
81 FR 29243 - Protection of Visibility: Amendments to Requirements for State Plans

81 FR 26942 - Protection of Visibility: Amendments to Requirements for State Plans
FR Doc. 2016-10228
FRL-9935-27-OAR
Comments. Written comments on this proposal must be received on or before July 5, 2016. Public hearing. The EPA is holding a public hearing concerning the proposed rule on May 19, 2016, in Washington, DC. The last day to pre-register to speak at the hearing is May 17, 2016. Please refer to SUPPLEMENTARY INFORMATION for additional information on submitting comments and the public hearing. Information collection request. Under the Paperwork Reduction Act (PRA), comments on the information collection provisions are best assured of having full effect if the Office of Management and Budget (OMB) receives a copy of your comments on or before June 3, 2016.
The Environmental Protection Agency (EPA) is proposing amendments to requirements under the Clean Air Act (CAA) for state plans for protection of visibility in mandatory Class I federal areas (Class I areas) in order to continue steady environmental progress while addressing administrative aspects of the program. The EPA amendments would clarify the relationship between long-term strategies and reasonable progress goals in state plans, and the long-term strategy obligation of all states. The amendments would also change the way in which some days during each year are to be selected for purposes of tracking progress towards natural visibility conditions to account for events such as wildfires; change aspects of the requirements for the content of progress reports; update, simplify and extend to all states the provisions for reasonably attributable visibility impairment and revoke existing federal implementation plans (FIPs) that require the EPA to assess and address any existing reasonably attributable visibility impairment situations in some states; and add a requirement for states to consult with Federal Land Managers (FLMs) earlier in the development of state plans. The EPA also proposes to address administrative aspects of the program by making a one-time adjustment to the due date for the next state implementation plans (SIPs), revising the due dates for progress reports and removing the requirement for progress reports to be SIP revisions.
81 FR 9339 - Air Quality: Revision to the Regulatory Definition of Volatile Organic Compounds—Requirements for t-Butyl Acetate
FR Doc. 2016-04072
RIN 2060-AR65
EPA-HQ-OAR-2013-0795
FRL-9942-80-OAR
This final rule is effective on April 25, 2016.
The Environmental Protection Agency (EPA) is amending the EPA&apos;s regulatory definition of volatile organic compounds (VOC) under the Clean Air Act (CAA). The regulatory definition of VOC currently excludes t-butyl acetate (also known as tertiary butyl acetate or TBAC; CAS Number: 540-88-5) for purposes of VOC emissions limitations or VOC content requirements on the basis that it makes a negligible contribution to tropospheric ozone formation. However, the current definition includes TBAC as a VOC for purposes of all recordkeeping, emissions reporting, photochemical dispersion modeling and inventory requirements which apply to VOC. This final action removes the recordkeeping, emissions reporting, photochemical dispersion modeling and inventory requirements related to the use of TBAC as a VOC.

FR Doc. 2015-32639
EPA-HQ-OAR-2015-0090, FRL-9937-21-OAR
Comments. Comments must be received on or before February 29, 2016. Public hearing. If anyone contacts us requesting a public hearing on or before January 13, 2016, we will hold a hearing. Additional information about the hearing, if requested, will be published in a subsequent Federal Register document.
80 FR 51052 - Data Requirements Rule for the 2010 1-Hour Sulfur Dioxide (SO 2 ) Primary National Ambient Air Quality Standard (NAAQS)
FR Doc. 2015-20367
RIN 2060-AR19
FRL-9928-18-OAR
This final rule is effective on September 21, 2015.
The Environmental Protection Agency (EPA) is promulgating a rule directing state and tribal air agencies (air agencies) to provide data to characterize current air quality in areas with large sources of sulfur dioxide (SO 2 ) emissions to identify maximum 1-hour SO 2 concentrations in ambient air. The final rule establishes minimum criteria for identifying the emissions sources and associated areas for which air agencies are required to characterize SO 2 air quality. Air agencies remain free to also characterize air quality in additional areas beyond those required to be characterized under the rule. The final rule also sets forth a process and timetables by which air agencies must characterize air quality through ambient monitoring and/or air quality modeling techniques and submit such data to the EPA. The EPA has issued separate non-binding draft technical assistance documents recommending how air agencies should conduct such monitoring or modeling. The air quality data developed by air agencies pursuant to this rule may be used by the EPA in future actions to evaluate areas&apos; air quality under the 2010 1-hour SO 2 National Ambient Air Quality Standard (NAAQS), including area designations and redesignations, as appropriate.
80 FR 50199 - Prevention of Significant Deterioration and Title V Permitting for Greenhouse Gases: Removal of Certain Vacated Elements
FR Doc. 2015-20501
EPA-HQ-OAR-2015-0414
FRL-9932-11-OAR
This rule is effective on August 19, 2015.
The Environmental Protection Agency (EPA) is amending its Prevention of Significant Deterioration (PSD) and title V regulations to remove from the Code of Federal Regulations portions of those regulations that were initially promulgated in 2010 and that the Court of Appeals for the District of Columbia Circuit (D.C. Circuit) specifically identified as vacated in the April 10, 2015, amended judgment, Coalition for Responsible Regulation v. EPA. This action is exempt from notice-and-comment rulemaking because it is ministerial in nature.
80 FR 45340 - Revision to the Guideline on Air Quality Models: Enhancements to the AERMOD Dispersion Modeling System and Incorporation of Approaches To Address Ozone and Fine Particulate Matter
FR Doc. 2015-18075
FRL-9930-11-OAR
Proposed rule; notice of conference.
Comments must be received on or before October 27, 2015. Public hearing and conference: The public hearing for this action and the Eleventh Conference on Air Quality Modeling will be held August 12-13, 2015, from 8:30 a.m. to 5:00 p.m.
In this action, the Environmental Protection Agency (EPA) proposes to revise the Guideline on Air Quality Models (“ Guideline ”). The Guideline has been incorporated into EPA&apos;s regulations, satisfying a requirement under the Clean Air Act (CAA) section 165(e)(3) for the EPA to specify, with reasonable particularity models to be used in the Prevention of Significant Deterioration (PSD) program. It provides EPA-preferred models and other recommended techniques, as well as guidance for their use in predicting ambient concentrations of air pollutants. The proposed revisions to the Guideline include enhancements to the formulation and application of the EPA&apos;s AERMOD near-field dispersion modeling system and the incorporation of a tiered demonstration approach to address the secondary chemical formation of ozone and fine particulate matter (PM 2.5 ) associated with precursor emissions from single sources. Additionally, the EPA proposes various editorial changes to update and reorganize information throughout the Guideline to streamline the compliance assessment process. Within this action, the EPA is also announcing the Eleventh Conference on Air Quality Modeling and invites the public to participate in the conference. The conference will focus on the proposed revisions to the Guideline and part of the conference will also serve as the public hearing for these revisions.
80 FR 8787 - Revisions to the Air Emissions Reporting Requirements: Revisions to Lead (Pb) Reporting Threshold and Clarifications to Technical Reporting Details
FR Doc. 2015-03470
FRL-9922-27-OAR
This final rule is effective on February 19, 2015.
This action finalizes changes to the Environmental Protection Agency&apos;s (EPA) emissions inventory reporting requirements. This action lowers the threshold for reporting lead (Pb) emissions sources as point sources, eliminates the requirement for reporting emissions from wildfires and prescribed fires, and replaces a requirement for reporting mobile source emissions with a requirement for reporting the input parameters that can be used to run the EPA models that generate emissions estimates. This action also reduces the reporting burden on state, local, and tribal agencies by removing the requirements to report daily and seasonal emissions in their submissions under this rule, while clarifying the requirement to report these emissions under pollutant-specific regulations. Lastly, this action modifies some emissions reporting requirements which we believe are not necessary for inclusion in the Air Emissions Reporting Requirements (AERR) rule or are not clearly aligned with current inventory terminology and practices.
