About this program

The Environmental Protection Agency funds competitive, peer-reviewed research under the Science to Achieve Results (STAR) program (CFDA 66.509) to advance understanding of environmental and public health protection, with the most recent grant award on March 1, 2025. The program has dispersed $914.1 million in combined federal and non-federal funding across 1,124 awards since its establishment in 2002, though award volume has declined significantly—from 39 awards in 2022 to only 6 through March 2025. STAR funds research on air quality, water quality and quantity, hazardous waste, toxic substances, pesticides, and environmental changes through predominantly Project Grants; the portfolio contains 1,121 Project Grants and only 3 Cooperative Agreements (99.7 percent Project Grants).

The Environmental Protection Agency itself accounts for 948 awards totaling $712.3 million federal dollars obligated, while the EPA Office of Research and Development accounts for 175 awards totaling $199.8 million. Typical recent awards range from under $200 thousand to $2 million, with recent funded research emphasizing per- and polyfluoroalkyl substances (PFAS) fate in agricultural and environmental systems, cumulative health burden assessment in environmental justice communities, landfill emissions monitoring, and sustainable chemistry transformation. Representative recent awards include projects developing nanosensing technology to detect and degrade PFAS in water ($1.5 million, October 2024), assessing PFAS bioaccumulation in tribal homelands and crops ($1.6 million, December 2024), and creating cumulative impact indices for chemical and non-chemical stressors across states ($2 million, January 2025).

Recent solicitations posted through July 2024 target nanosensor technology for PFAS detection and degradation, air quality data integration and communication in underserved communities, coastal ecosystem climate resilience, sustainable chemistry, and PFAS uptake in agricultural and rural settings. The program expects applications for research addressing environmental justice, climate change vulnerability, and community-engaged solutions. Grant opportunities remain active; the most recent open solicitation (EPA-G2024-STAR-G1, nanosensor technology) closed November 2024, and historical cadence suggests new NOFOs post quarterly to semi-annually aligned with EPA research priorities.

Uses of assistance

Funds awarded via grants/cooperative agreements are available for allowable direct cost expenditures associated with the performance of research plus allocable portions of allowable indirect costs of the institutions, in accordance with established EPA policies and regulations. Applicants must propose EPA mission relevant research based on excellent science as determined through peer review by experts drawn from the national and international scientific community. Other more specialized scientific areas may be solicited via joint funding opportunities with other Federal agencies. The STAR program may fund research centers that focus on long-term, multi-disciplinary research. Assistance agreement awards under this program may involve or relate to geospatial information. Further information regarding geospatial information may be obtained by viewing the following website: https://www.epa.gov/geospatial.

Use restrictions

The funding mechanism for all awards issued under STAR solicitations will consist of assistance agreements from the EPA. All award decisions are subject to the availability of funds. In accordance with the Federal Grant and Cooperative Agreement Act, 31 U.S.C. 6301 et seq., the primary purpose of an assistance agreement is to accomplish a public purpose of support or stimulation authorized by federal statute, rather than acquisition for the direct benefit or use of the Agency. EPA award recipients may incur allowable project costs 90 calendar days before the Federal awarding agency makes the Federal award. Expenses more than 90 calendar days pre-award require prior approval of EPA. All costs incurred before EPA makes the award are at the recipient's risk. EPA is under no obligation to reimburse such costs if for any reason the recipient does not receive a Federal award or if the Federal award is less than anticipated and inadequate to cover such costs. If you wish to submit applications for more than one STAR funding opportunity, you must ensure that the research proposed in each application is significantly different from any other that has been submitted to the EPA or from any other financial assistance you are currently receiving from the EPA or other federal government agency. Collaborative applications involving more than one institution must be submitted as a single administrative package from one of the institutions involved. Each proposed project must be able to be completed within the project period. Applicants should request the entire amount of money needed to complete the project. Some solicitations issued under this assistance listing may allow for the submittal of Multiple Investigator applications. The applicability of Multiple Investigator applications will be described in the solicitations. For further information, please see the EPA Implementation Plan for Policy on Multiple Principal Investigators (https://www.epa.gov/research-grants/research-grants-guidance-and-policies).

Length and time phasing of assistance

Grants are normally funded for a minimum of 3 years (over 180 days). Total approved project period may not exceed 5 years.
