About the company
Maricopa County Air Quality Department, operating as the Department Of Air Quality, is a U.S. local government entity and division of Maricopa County Finance Department that receives federal grant funding to operate ambient air quality monitoring networks, implement air pollution control programs, and administer vehicle emissions reduction initiatives as a grant recipient. The department operates exclusively as a prime recipient (100% of awards); it does not compete for federal contracts or hold seats on contract vehicles, and it does not function as a subcontractor.
The department's federal footprint centers on environmental monitoring and air quality management funded by the Environmental Protection Agency Region 9. Across 46 awards since 2006, the department has received $192.2 million in obligated federal dollars, with recent activity spanning EPA air quality grants, Federal Highway Administration electric vehicle infrastructure funding, and smaller Department of the Air Force and Department of Veterans Affairs awards. EPA Region 9 dominates the customer set: 16 named EPA awards make up 85% of recent grant volume. Representative work includes a $6.676 million Federal Highway Administration Highway Planning and Construction grant (CFDA 20.205) awarded in November 2024 for the Maricopa County Electric Vehicle Infrastructure Improvement Project, which funds EV charging deployment, legacy diesel vehicle replacement with alternative-fuel and electric models, and air quality monitoring through December 2029; multiple EPA Clean Air Act monitoring grants ($88,730 to $120,320 per award) for PM2.5 network operation and data collection to the National Air Quality Database; a $662,488 EPA project grant under CFDA 66.034 (Surveys, Studies, Research, Investigations, Demonstrations, and Special Purpose Activities Relating to the Clean Air Act), funded under the Inflation Reduction Act, to establish a PM2.5 speciation study at two air monitoring sites in areas with sensitive populations; a $1.147 million EPA Section 105 formula grant for air pollution control program implementation including NAAQS analysis, emissions inventory, and permitting; and a $667,812 EPA-funded Clean Diesel Grant Program award through which the department subawards to school districts and private commercial entities for replacement of school buses, shuttle buses, delivery trucks, and tractors with alternative-fuel and electric vehicles.
Activity has been episodic: one award in 2022, four each in 2023 and 2024, declining to one in 2025 and one in 2026. Two awards face ultimate completion within the next twenty-four months, representing modest recompete exposure. The department operates no federal contract vehicles, holds no parent IDIQs or GWACs, and does not compete under set-aside categories. All federal funding flows through EPA Region 9 grant mechanisms (CFDA 66.001, 66.034, 66.040) and the Federal Highway Administration, with work performed in Maricopa County, Arizona.
