“Ms. Laura M. Crowder, Director

Division of Air Quality

West Virginia Department of Environmental Protection

601 57th Street SE

Charleston, West Virginia 25304

                        Via email at                         *laura.m.crowder@wv.gov*

Dear Ms. Crowder:

This letter acknowledges your letter dated May 1, 2023 in which the West Virginia Department of Environmental Protection (WVDEP) Division of Air Quality (DAQ) informed the United States Environmental Protection Agency (EPA) that West Virginia had updated its incorporation by reference of federal National Emissions Standards for Hazardous Air Pollutants (NESHAP) and New Source Performance Standards (NSPS) to include many such standards as found in 40 CFR parts 60, 61, and 63 as of June 1, 2022. WVDEP DAQ noted in the letter that it understood it was automatically delegated the authority to implement these standards. WVDEP DAQ stated its intent to enforce the standards in conformance with the terms of EPA's previous delegations of authority pursuant to the EPA final rules published at 49 FR 48692 and 67 FR 15486, and EPA delegation letters.

In two rulemakings, 49 FR 48692 (December 14, 1984) and 67 FR 15486 (April 2, 2002), EPA established the basis for delegation to West Virginia of specified federal standards at 40 CFR parts 60, 61, and 63. Subsequently, in a letter dated March 19, 2001 to WVDEP Director Michael Callaghan, EPA delegated to the State of West Virginia the authority to implement and enforce various federal NESHAP found in 40 CFR part 63. In another letter to Director Callaghan dated January 8, 2002, EPA delegated to the State of West Virginia the authority to implement and enforce various federal NESHAP found in 40 CFR part 61 and NSPS found in 40 CFR part 60. In those letters, EPA also established that future part 60, part 61, and part 63 standards would be automatically delegated to West Virginia subject to the conditions set forth in those letters. Those rulemakings and letters continue to control the conditions of delegation of future standards and their terms should be consulted for the specific conditions that apply to each regulatory program. However, in general terms, for automatic delegation to take effect, the letters establish conditions that can be paraphrased as requiring: legal adoption of the standards; restrictions on the kinds of wording changes West Virginia may make to the federal standards when adopting them; and specific notification from West Virginia to EPA when a standard has been adopted.

                        WVDEP DAQ provided copies of the revised West Virginia Legislative Rules which specify the NESHAP and NSPS regulations 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, 2023. EPA has reviewed the revised rules and determined that they meet the conditions for automatic delegation as established by EPA in its prior letters and rulemakings.                              ( print page 83941)    

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, effective on June 1, 2023.

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

Sincerely, 

Cristina Fernández, Director 

Air and Radiation Division”
