Environmental Protection Agency February 7, 2019 – Federal Register Recent Federal Regulation Documents

Revised Definition of “Waters of the United States”
Document Number: 2019-01483
Type: Proposed Rule
Date: 2019-02-07
Agency: Department of Defense, Environmental Protection Agency, Department of the Army, Corps of Engineers
On December 11, 2018, the Environmental Protection Agency and the U.S. Department of the Army (the agencies) signed a proposed rule revising the definition of ``waters of the United States'' to clarify the scope of waters federally regulated under the Clean Water Act. The agencies are announcing that a public hearing will be held in Kansas City, Kansas on February 27 and 28, 2019, to provide interested parties the opportunity to present data, views, or information concerning the proposed rule. The pre-publication version of this proposal can be found at https://www.epa.gov/wotus-rule/step-two-revise.
Standards of Performance for New Residential Wood Heaters, New Residential Hydronic Heaters and Forced-Air Furnaces
Document Number: 2019-01366
Type: Proposed Rule
Date: 2019-02-07
Agency: Environmental Protection Agency
On November 30, 2018, the Environmental Protection Agency (EPA) proposed a rule titled ``Standards of Performance for New Residential Wood Heaters, New Residential Hydronic Heaters and Forced- Air Furnaces.'' The EPA is reopening the public comment period on the proposed rule that closed on January 14, 2019. The EPA is taking this action to allow time for the public to comment on the proposed rule for at least 30 days following the public hearing, which was held on December 17, 2018.
Review of Standards of Performance for Greenhouse Gas Emissions From New, Modified, and Reconstructed Stationary Sources: Electric Utility Generating Units
Document Number: 2019-01365
Type: Proposed Rule
Date: 2019-02-07
Agency: Environmental Protection Agency
On December 6, 2018, the Environmental Protection Agency (EPA) proposed a rule titled ``Review of Standards of Performance for Greenhouse Gas Emissions from New, Modified, and Reconstructed Stationary Sources: Electric Utility Generating Units.'' The EPA is extending the public comment period from February 19, 2019, until March 18, 2019, which is consistent with the requirement to keep the record open for at least 30 days after the public hearing, which is scheduled for February 14, 2019, in Washington, DC. Information about the public hearing was posted online on January 30, 2019, and can be found at https://www.epa.gov/stationary-sources-air-pollution/proposal -nsps-ghg- emissions-new-modified-and-reconstructed-egus.
Regulation of Fuels and Fuel Additives: Removal of the Reformulated Gasoline Program From the Northern Kentucky Portion of the Cincinnati-Hamilton Ozone Maintenance Area
Document Number: 2019-01320
Type: Rule
Date: 2019-02-07
Agency: Environmental Protection Agency
In this final action, EPA is amending its reformulated gasoline regulations to reflect that Boone, Campbell, and Kenton counties in Kentucky (the Northern Kentucky Area), which are part of the Cincinnati-Hamilton, Ohio-Kentucky-Indiana ozone area, are no longer federal reformulated gasoline (RFG) covered areas as of July 1, 2018. As described in a separate document published on May 16, 2018, pursuant to EPA's regulations, EPA approved an April 18, 2017 petition from the state of Kentucky to opt-out of the federal RFG program and removed the requirement to sell federal RFG in the Northern Kentucky Area as of July 1, 2018. This effective date applies to retailers, wholesale purchaser-consumers, refiners, importers, and distributors. This rulemaking merely conforms the list of RFG covered areas in the regulations to reflect the effective date of the opt-out for the Northern Kentucky Area.
Glycine betaine; Exemption From the Requirement of a Tolerance
Document Number: 2019-01307
Type: Rule
Date: 2019-02-07
Agency: Environmental Protection Agency
This regulation establishes an exemption from the requirement of a tolerance for residues of glycine betaine (CAS Reg. No. 107-43-7) when used as an inert ingredient (plant nutrient) in pesticide formulations applied to growing crops only. SciReg, Inc., on behalf of Fine Agrochemicals Ltd, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of glycine betaine.
National Emission Standards for Hazardous Air Pollutants: Coal- and Oil-Fired Electric Utility Steam Generating Units-Reconsideration of Supplemental Finding and Residual Risk and Technology Review
Document Number: 2019-00936
Type: Proposed Rule
Date: 2019-02-07
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is proposing a revision to its response to the U.S. Supreme Court decision in Michigan v. EPA which held that the EPA erred by not considering cost in its determination that regulation under section 112 of the Clean Air Act (CAA) of hazardous air pollutant (HAP) emissions from coal- and oil- fired electric utility steam generating units (EGUs) is appropriate and necessary. After considering the cost of compliance relative to the HAP benefits of regulation, the EPA proposes to find that it is not ``appropriate and necessary'' to regulate HAP emissions from coal- and oil-fired EGUs, thereby reversing the Agency's prior conclusion under CAA section 112(n)(1)(A) and correcting flaws in the Agency's prior response to Michigan v. EPA. We further propose that finalizing this new response to Michigan v. EPA will not remove the Coal- and Oil-Fired EGU source category from the CAA section 112(c) list of sources that must be regulated under CAA section 112(d) and will not affect the existing CAA section 112(d) emissions standards that regulate HAP emissions from coal- and oil-fired EGUs. We are soliciting comment, however, on whether the EPA has the authority or obligation to delist EGUs from CAA section 112(c) and rescind (or to rescind without delisting) the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired EGUs, commonly known as the Mercury and Air Toxics Standards (MATS). The EPA is also proposing the results of the residual risk and technology review (RTR) of the NESHAP that the Agency is required to conduct in accordance with CAA section 112. The results of the residual risk analysis indicate that residual risks due to emissions of air toxics from this source category are acceptable and that the current standards provide an ample margin of safety to protect public health. No new developments in HAP emission controls to achieve further cost-effective emissions reductions were identified under the technology review. Therefore, based on the results of these analyses and reviews, we are proposing that no revisions to MATS are warranted. Finally, the EPA is also taking comment on establishing a subcategory for emissions of acid gas HAP from existing EGUs firing eastern bituminous coal refuse.
Approval and Promulgation of Air Quality Implementation Plans; State of Colorado; Motor Vehicle Inspection and Maintenance Program and Associated Revisions
Document Number: 2019-00713
Type: Rule
Date: 2019-02-07
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is approving two State Implementation Plan (SIP) revisions submitted by the State of Colorado. The revisions involve amendments to Colorado's Regulation Number 11, ``Motor Vehicle Emissions Inspection Program.'' The revisions enhance the use of Regulation Number 11's Clean Screen Program, allow self-inspecting vehicle fleets to use the On-Board Diagnostics (OBD) testing procedure, provide corrections to the Low Emitter Index (LEI) component of the Clean Screen Program, clarify existing provisions, correct administrative errors, delete obsolete language, establish inspection procedures for when emission control equipment tampering is detected, and make several other minor associated revisions. These actions are being taken under section 110 of the Clean Air Act (CAA).
