NOTICE OF PUBLIC HEARING

KENTUCKY DIVISION FOR AIR QUALITY

TO REVISE KENTUCKY’S STATE IMPLEMENTATION PLAN AND

AIR QUALITY REGULATIONS

The Kentucky Energy and Environment Cabinet will conduct a public hearing on July 24, 2012, at 10:00 a.m. 

(Local Time) in Conference Room 201B of the Division for Air Quality, 200 Fair Oaks Lane, Frankfort, 

Kentucky. This hearing will be held to receive comments on the following proposed administrative regulations:

401 KAR 51:001. Definitions for 401 KAR Chapter 51. (Amendment)

401 KAR 51:017. Prevention of significant deterioration of air quality. (Amendment)

401 KAR 51:052. Review of new sources in or impacting upon nonattainment areas. (Amendment)

The amendments to these administrative regulations revise definitions to reflect the New Source Review (NSR) 

program at the federal level. The amendments include the requirements necessary to determine whether a 

construction project’s emissions will cause or contribute to a violation of the PM2.5 NAAQS. This regulatory 

action establishes significant impact levels, significant monitoring concentrations, and baseline dates for the PM2.5

NAAQS. Also, the amendments adopt the significant emissions rates to determine NSR applicability for PM2.5

and PM2.5 precursors. The definition of “Regulated NSR pollutant” has been amended for consistency with the 

corresponding federal definition.

This hearing is open to the public and all interested persons will be given the opportunity to present testimony. 

To assure that all comments are accurately recorded, the Division requests that oral comments presented at the 

hearing are also provided in written form, if possible. Written comments must be received by close of business on

July 31, 2012, to be considered part of the hearing record. The Energy and Environment Cabinet does not 

discriminate on the basis of race, color, national origin, sex, age, religion, or disability and provides, upon request, 

reasonable accommodation including auxiliary aids and services necessary to afford an individual with a 

disability an equal opportunity to participate in all services, programs, and activities.

The full texts of the proposed regulations are available for public inspection and copying during regular business 

hours (8:00 a.m. to 4:30 p.m., Local Time) at the locations listed below. Any individual requiring copies may 

submit a request to the Division for Air Quality in writing, by telephone, by fax, or by e-mail. Requests for copies
