The bill amends Title 74 of the Pennsylvania Consolidated Statutes by establishing the Supplemental Public Transportation Operating Assistance Allocation for Growing Counties Grant Program. This program is designed to provide operating assistance to eligible entities in counties that are experiencing growth in either population or employment. The Department of Transportation is tasked with administering the program, which includes creating an annual grant application process and developing guidelines for additional grant requirements. Eligible entities include those that have received grants under existing sections related to operating programs or programs of statewide significance.

The bill outlines specific criteria for determining eligibility based on employment and population growth, utilizing data from the Department of Labor and Industry and the U.S. Census Bureau. It stipulates that grant funds will be allocated equally between counties growing in employment and those growing in population, with the total amount awarded based on proportional shares of growth. Additionally, the bill ensures that appropriated funds for this program are separate from existing allocations and limits local match requirements to those specified in current law. The act is set to take effect 60 days after its passage.
