Congestion Mitigation and Air Quality Improvement (CMAQ) and Regional Surface Transportation (RSTP) Program Funding

In addition to managing and programming HB 2313 revenues, the Authority handles Northern Virginia’s annual programming of CMAQ and RSTP funds, which are part of the overall mix of transportation funding available to Northern Virginia. With regional collaboration in mind, the Authority’s executive director works with the Regional Jurisdiction and Agency Coordinating Committee (RJACC) to recommend the programming of more than $83 million annually for CMAQ and RSTP funded projects. NVTA’s projects recommended for CMAQ and RSTP funding are subject to approval by the Commonwealth Transportation Board (CTB).

CMAQ Allocation

In the United States, regions found to be in non-attainment for air quality standards (air pollution), like Northern Virginia, are eligible for federal CMAQ funds. The eligible projects as per the most recent federal surface transportation legislation, Fixing America’s Surface Transportation (FAST) Act, along with its predecessor Moving Ahead for Progress in the 21st Century (MAP 21), include transit, non-recreational bike and pedestrian facilities, alternate fuel projects, diesel retrofits, traffic monitoring/management/control facilities, signals, intersection improvements, intelligent transportation systems (ITS), teleworking, ride-sharing, etc. In February 2018, the NVTA recommended $22.8 million in FY2024 funding for projects for CTB approval. The allocation for FY2019-FY2024 is shown in the table below.

Allocation of CMAQ Funds


FY2019 FY2020 FY2021 FY2022 FY2023 FY2024
CMAQ $21,506,170 $21,512,010 $21,512,010 $21,584,051 $21,584,051 $15,998,216
CMAQ 2.5 $8,014,165 $8,014,165 $8,014,165 $8,014,165 $8,014,165 $6,857,064
TOTAL $29,520,335 $29,526,175 $29,526,175 $29,598,216 $29,598,216 $22,855,280


RSTP Allocation

RSTP provides flexible funding to Northern Virginia, and similar regions across the country, that may be used for projects to improve and preserve conditions and performance on federal-aid highways, public bridges and tunnels, bicycle and pedestrian infrastructure, and transit capital projects. In Virginia, these funds are available to Metropolitan Planning Organizations (MPOs) with populations greater than 200,000. While the NVTA is not a federally designated MPO, it fulfills this function for Northern Virginia.  In February 2018, the NVTA recommended the programming of $54.7 million in RSTP FY2024 funding for CTB approval.  The allocation for FY2019 – FY2024 is found in the table below.

In 2018, CMAQ and RSTP funding availability was revised for FY2019-FY2024, totaling a reduction of $6.7 million in CMAQ funds and addition of $7.2 million in RSTP funds over the six-year period, due to revised allocations under the FAST Act. NVTA staff and the RJACC worked to ensure timely programming of these funds.
