All notifications, applications, reports, and other correspondence required pursuant to the delegated NESHAP and NSPS must be submitted to both EPA Region III and to the West Virginia Department of Environmental Protection, unless the delegated standard specifically provides that such submittals may be sent to EPA or a delegated State. In such cases, the submittals should be sent only to the West Virginia Department of Environmental Protection. A copy of EPA's October 8, 2020 letter to West Virginia follows:

Mr. Laura M. Crowder, Director

Division of Air Quality

West Virginia Department of Environmental Protection

601 57th Street SE

Charleston, West Virginia 25304

Dear Ms. Crowder:

The United States Environmental Protection Agency (EPA) has previously delegated to the State of West Virginia the authority to implement and enforce various federal National Emissions Standards for Hazardous Air Pollutants (NESHAP) and New Source Performance Standards (NSPS), which are found at 40 CFR parts 60, 61, and 63. In those actions EPA also delegated to West Virginia the authority to implement and enforce any future EPA NESHAP or NSPS on the condition that West Virginia legally adopt the future standards, make only allowed wording changes, and provide specified notice to EPA.

In a letter dated May 6, 2019, West Virginia informed EPA that West Virginia had updated its incorporation by reference of federal NESHAP and NSPS to include many such standards as found in 40 CFR parts 60, 61, and 63 as of June 1, 2018. In a letter dated June 3, 2020, West Virginia informed EPA that West Virginia had updated its incorporation by reference of federal NESHAP and NSPS to include many such standards as found in 40 CFR parts 60, 61, and 63 as of June 1, 2019. West Virginia noted in both letters that it understood it was automatically delegated the authority to implement these standards. West Virginia committed to enforcing the standards in conformance with the terms of EPA's previous delegations of authority. West Virginia made only allowed wording changes.

West Virginia provided copies of the revised West Virginia Legislative Rules which specify the NESHAP and NSPS which West Virginia has adopted by reference. These revised Legislative Rules are entitled 45 CSR 34—“Emission Standards for Hazardous Air Pollutants,” and 45 CSR 16—“Standards of Performance for New Stationary Sources.” These revised Rules have an effective date of June 1, 2019 for the 2019 letter and June 1, 2020 for the 2020 letter.

Accordingly, EPA acknowledges that West Virginia now has the authority, as provided for under the terms of EPA's previous delegation actions, to implement and enforce the NESHAP and NSPS standards which West Virginia adopted by reference in West Virginia's revised Legislative Rules 45 CSR 34 and 45 CSR 16, as effective on June 1, 2019 and subsequently on June 1, 2020.

                        Please note that on December 19, 2008 in Sierra Club vs. EPA,[1]                                                  the United States Court of Appeals for the District of Columbia Circuit vacated certain provisions of the General Provisions of 40 CFR part 63 relating to exemptions for startup, shutdown, and malfunction (SSM). On October 16, 2009, the Court issued the mandate vacating these SSM exemption provisions, which are found at 40 CFR part 63, 63.6(f)(1), and (h)(1).                    

Accordingly, EPA no longer allows sources to use the SSM exemption as provided for in the vacated provisions at 40 CFR 63.6(f)(1), and (h)(1), even though EPA has not yet formally removed the SSM exemption provisions from the General Provisions of 40 CFR part 63. Because West Virginia incorporated 40 CFR part 63 by reference, West Virginia should also no longer allow sources to use the former SSM exemption from the General Provisions of 40 CFR part 63 due to the Court's ruling in Sierra Club vs. EPA.

EPA appreciates West Virginia's continuing NESHAP and NSPS enforcement efforts, and also West Virginia's decision to take automatic delegation of additional and more recent NESHAP and NSPS by adopting them by reference.

If you have any questions, please contact me or Ms. Mary Cate Opila, Chief, Permits Branch, at 215-814-2041.

Sincerely,

Cristina Fernandez, Director

Air and Radiation Division

EPA Region III

This notice acknowledges the updates of West Virginia's delegation of authority to implement and enforce NESHAP and NSPS.

Dated: November 17, 2020.

Cristina Fernandez,

Director,  Air & Radiation Division, Region III.
