The FHWA withdraws its August 4, 2014, Notice of Proposed Rulemaking (NPRM), which proposed to establish a weighting factor of 5.0, to be used in determining the weighted population of fine particulate (PM<INF>2.5</INF>) nonattainment areas. The Moving Ahead for Progress in the 21st Century Act (MAP-21) language for the CMAQ Program funds that must be obligated for PM<INF>2.5</INF> projects in PM<INF>2.5</INF> nonattainment and maintenance areas (referred to in this document as a "set-aside") instructs that the set-aside be calculated based on "weighted population" in PM<INF>2.5</INF> nonattainment areas. Because the statute did not specify the values to be applied to determine the weighted population, FHWA had previously initiated a rulemaking to establish the weighting factor. After reviewing the record in this matter, FHWA withdraws the NPRM.
