SUPPLEMENTARY INFORMATION: On July 25, 2023, EPA received a letter from
the LMAPCD requesting delegation of authority to implement and enforce
the Federal NSPS using the ``adopt-by-reference'' mechanism. Section
111(c)(1) of the CAA authorizes EPA to delegate the authority to
implement and enforce the NSPS set out in part 60 of title 40, chapter
I, subchapter C of the Code of Federal Regulations (CFR) to State and
local agencies that develop and submit to EPA an adequate procedure for
implementing and enforcing the NSPS. After a thorough review of the
request, EPA has determined that the LMAPCD's regulations provide an
adequate procedure for implementing and enforcing current and future
NSPS. EPA, therefore, hereby notifies the public that it has approved
the LMAPCD's request for delegation of authority to implement and
enforce all existing promulgated NSPS subparts that are delegable, and
any future new or revised subparts that are delegable, using the
``adopt-by-reference'' mechanism. This approval became effective on
August 30, 2024. With this NSPS delegation mechanism in place, once EPA
promulgates a new or revised delegable NSPS subpart, delegation of
authority from EPA to the LMAPCD will become effective on the date when
the delegable NSPS subpart is adopted by the LMAPCD into its local
rules. No further requests from the local agency for delegation will be
necessary. Likewise, no further Federal Register notices will be
published.
Under CAA section 111(c)(2), EPA reserves the right to implement
the Federal NSPS directly and continues to retain concurrent
enforcement authority. Effective August 30, 2024, and unless otherwise
specified by the NSPS rules for reporting purposes, the information
required pursuant to the Federal NSPS must be submitted by sources
located inside the jurisdictional boundaries of the LMAPCD to the
following address: Louisville Metro Air Pollution Control District, 701
West Ormsby Avenue, Suite 303, Louisville, Kentucky 40203-3137. The
LMAPCD is the primary point of contact with respect to delegated NSPS
authorities. For those authorities not delegated, sources must continue
to submit all required information to EPA. As mentioned above, this
notice acknowledges EPA's approval of the LMAPCD's request for
delegation of authority to implement and enforce delegable NSPS using
the ``adopt-by-reference'' mechanism.
Dated: June 25, 2025.

Regional Administrator, Region 4.
