About this program

The Environmental Protection Agency administers the Environmental Information Exchange Network Grant Program (CFDA 66.608) to fund IT and data management infrastructure enabling states, territories, and federally recognized Indian tribes to collect, exchange, and share environmental data with EPA and one another, with the most recent grant awards disbursed on October 1, 2025, and an open solicitation due October 22, 2025.

The program funds the development and modernization of IT systems and databases that support electronic environmental data collection, reporting, and exchange across the full range of EPA-regulated domains—water quality monitoring, air quality compliance, hazardous waste tracking, drinking water systems, permitting, and related environmental programs. Recent awards exemplify the scope: the Klamath Tribes built data pipelines and web applications for water quality data access ($294,005); the Shoshone-Paiute Tribes expanded data-sharing platforms and developed a public data portal ($299,926); the Native American Environmental Protection Coalition streamlined UST/LUST data reporting to EPA ($500,000); and state environmental agencies funded database modernization, electronic reporting systems for NPDES permitting and water quality assessments, and geospatial data platforms. Funding supports both upstream infrastructure—standardizing data schemas, creating APIs, integrating legacy datasets—and downstream user interfaces including mobile field data collection apps, public web portals, and analytical dashboards.

The portfolio consists almost entirely of Project Grants (1,064 of 1,069 awards, 99.5 percent) with minimal Cooperative Agreements. The Environmental Protection Agency dominates as the funding source with 829 awards totaling $213.3 million in federal dollars obligated, followed by the EPA Office of Administration and Resource Management (218 awards, $60 million) and EPA Headquarters Procurement Operations (15 awards, $2.9 million). Combined federal obligations across all funders total $277.6 million over the program's 33-year history since 1992.

Award activity remains steady but has declined in recent years. The program averaged 40–30 awards annually from 2021–2023, falling to 23 awards in 2024 and 7 in the partial 2025 year reflected in the data. Representative recent award magnitudes cluster in the $200,000–$500,000 range for single-recipient projects, with a few outliers above $500,000 (University of Vermont received $500,000 for mountain observatory data standardization; Eight Northern Indian Pueblos Council received $500,000 for multi-tribal consortium infrastructure).

FY 2025 solicitation EPA-OMS-25-01 opened January 13, 2025, with application due October 22, 2025 (extended from an earlier April 30, 2025 deadline). The solicitation targets projects that facilitate shared and reusable environmental data services, reduce burden on co-regulators and the regulated community, streamline data collection and exchanges, and increase data quality and access through discovery, publishing, and analytical services. Applicant types include states, territories, tribes, universities, nonprofits, and other entities engaged in environmental data management. No preapplication consultation requirement is stated in the program description, though the NOFO specifies details on assistance available.

Grants are awarded as Project Grants and Cooperative Agreements with a 12-month performance period extendable up to four consecutive one-year no-cost extensions, with a 7-year maximum grant lifetime. All awards are subject to EPA audit and administrative compliance review under 2 CFR 1500.

Objective and description

Objective

The National Environmental Information Exchange Network (EN) is an inter-governmental partnership to foster better environmental management and decision-making through increased access to timely and high-quality environmental information. The EN, lau

Description

The Exchange Network Grant Program provides funding to states, territories, and federally recognized Indian tribes to support the development of the National Environmental Information Exchange Network (EN). The primary outcome expected from Exchange Network assistance agreements is improved access to, and exchange of, high-quality environmental data from public and private sector sources.

Eligibility

Applicant eligibility

Consistent with the Assistance Listing for 66.608, eligible applicants for the Exchange Network Grant program include states, U.S. Territories (i.e., American Samoa, the Commonwealth of the Northern Mariana Islands, the District of Columbia, Guam, Palau, Puerto Rico, the U.S. Virgin Islands), federally recognized Indian tribes and Alaska Native Villages and inter-tribal consortia of federally recognized tribes (e.g., the Northwest Indian Fisheries Commission). Other entities, such as regional air pollution control districts and some public universities may apply for assistance if they are agencies or instrumentalities of a state or tribe under applicable laws. Entities asserting they are agencies or instrumentalities of a state must provide a letter from the appropriate state Attorney General certifying the applicant is an agency or instrumentality of the state. Entities asserting they are instrumentalities of a tribe must provide a certification and supporting documentation from the tribal council or other appropriate tribal government official certifying they are an instrumentality of the tribe. EPA will not accept or review an application which does not include the required documentation. The EPA recognizes that environmental programs and associated reporting obligations are sometimes delegated to local governments. Local governments are eligible to apply for EN assistance agreements if they can demonstrate that they are an instrumentality of the state by providing the documentation described in the preceding paragraph. However, most local governments implementing EPA programs are not agencies or instrumentalities of the state and therefore not eligible to apply. EPA encourages such entities to partner with an eligible lead applicant (e.g., a state applicant) to allow for their data to be reported and shared through the EN. Interstate commissions and other interstate entities, likewise, are not eligible to apply and are encouraged to partner with a state applicant.

Beneficiary eligibility

Eligible applicants for the EN Grant Program include states, the District of Columbia, U.S. territories (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands), federally recognized Indian tribes, and intertribal consortia of federally recognized tribes. Other entities, such as regional air pollution control districts and some public universities may apply for assistance if they are agencies or instrumentalities of a state or tribe under applicable laws.

Uses of assistance

Applicants may propose EN project funding for costs associated with personnel salaries and fringe benefits, Intergovernmental Personnel Act Agreements (IPAs) travel, travel related to Exchange Network activities, equipment, supplies, contractual costs, in-kind services provided by EPA, and indirect costs. Applicants may propose EN project funding for development, modernization, and enhancement activities. 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: Geospatial Resources at EPA (https://www.epa.gov/geospatial).

Use restrictions

Applicants may not use EN funding for the following functions : Construction costs; operations and maintenance including previously developed and implemented EN projects; workshops and conferences that are not initiated, advertised, and conducted for the benefit of the recipient and other state, tribal, territorial, or local representatives or public participants or are conducted primarily for EPA's benefit; pre-award costs not previously requested to cover pre-award costs incurred 90 days or less before the award date; management fees more than the direct costs and indirect costs at the rate approved by the applicant's cognizant audit agency, or at the rate provided for by the terms of the agreement negotiated with EPA; development and deployment of partner physical nodes. This program makes Federal awards on a discretionary basis. A discretionary award means an award in which the Federal awarding agency, in keeping with specific statutory authority that enables the agency to exercise judgement ("discretion"), selects the recipient and/or the amount of Federal funding awarded through a competitive process or based on merit of proposals. For further information, please contact the Headquarters or regional office.

Length and time phasing of assistance

EPA plans to issue awards for applications that are recommended for funding approximately four months after the application deadline. The standard period of performance for projects funded by the EN Grant Program is three years. EPA may consider requests from award recipients for project/budget period extensions; and if deemed appropriate by EPA, the Grants and Interagency Agreements Management Division may issue amendments extending the project/budget periods for one year, up to four times.

How to apply

Preapplication coordination

Preapplication coordination is required. Environmental impact information is not required for this program. This program is excluded from coverage under E.O. 12372. Regarding pre-application assistance with respect to competitive funding opportunities under this assistance listing, EPA will generally specify the nature of the pre-application assistance, if any, that will be available to applicants in the NOFO.

Criteria for selecting proposals

The complete evaluation and selection criteria for competitive awards under this assistance listing will be described in the NOFO.

Award procedure

For competitive awards, EPA will review and evaluate applications in accordance with the terms, conditions, and criteria stated in the competitive announcement. Competitions will be conducted in accordance with EPA policies/regulations for competing assistance agreements. For non-competitive awards made under this assistance listing, EPA will conduct an administrative evaluation to determine the adequacy of the application in relation to grant regulations and to technical and program evaluation to determine the merit and relevance of the project. The Agency will then advise the applicant if funding is being considered. A final work plan will then be negotiated with the applicant.
