Opportunity Information: Apply for EPA R3 CBP 23 07
The Environmental Protection Agency (EPA), through its Chesapeake Bay Program Office, released a Fiscal Year 2023 Request for Applications titled "Chesapeake Bay Watershed Modeler" (Funding Opportunity Number: EPA R3 CBP 23 07). This is a discretionary funding opportunity using a cooperative agreement, meaning the EPA anticipates substantial involvement during the project period rather than a hands-off grant. The program aligns with the EPA environmental assistance portfolio under CFDA 66.466 and is focused on advancing the technical modeling capacity that underpins Chesapeake Bay restoration decisions.
The core purpose of the opportunity is to support the application of a state-of-the-science, fine-scale Watershed Model (WSM) for the Chesapeake Bay watershed. In practical terms, the funded work is intended to quantify watershed flows and resulting nutrient and sediment loads across the Chesapeake drainage area. The model is expected to be capable of evaluating conditions across the full range of watershed management situations, and it must also be able to account for both current climate conditions and projected future climate conditions. The modeling outputs are not just academic; they are meant to be directly usable by Chesapeake Bay decision-makers to run scenarios and test how different management strategies may perform.
A central driver for this work is the Chesapeake Bay Total Maximum Daily Load (TMDL), which sets water quality standards and associated pollutant reduction targets for the Bay and its tributaries. The WSM scenarios developed or supported under this award are intended to inform the management strategies needed to meet those TMDL standards. The opportunity is also explicitly tied to evaluating whether Chesapeake TMDL water quality standards can be achieved under 2035 climate conditions, which signals a strong emphasis on scenario analysis that integrates climate change considerations alongside land and watershed management actions.
The RFA is closely connected to development of the Phase 7 Watershed Model, which at the time of the announcement was under development. Phase 7 is positioned as the next major iteration of the Chesapeake Bay watershed modeling system used to support policy, planning, and accountability across jurisdictions. The notice states that Phase 7 is expected to be completed and fully operational by December 2025, indicating that the funded applicant would be working within a defined timeline and likely coordinating deliverables to support that broader schedule. The overall intent is to ensure the Chesapeake Bay partnership has a fully functioning modeling platform that is credible, fine-scale, and capable of assessing management and climate-driven futures.
From an administrative standpoint, the opportunity was posted on April 3, 2023, with an original closing date of May 18, 2023 (with applicants directed to consult Section IV of the full funding announcement for detailed submission timing and requirements). The EPA anticipated making one award under this competition. The maximum award amount listed is $1,377,000, which reflects the scale of work expected for sophisticated watershed modeling and decision-support scenario development within a cooperative agreement structure.
Eligibility is listed broadly as "Others," with clarification deferred to the funding announcement section titled "Additional Information on Eligibility." That phrasing typically indicates the competition may be open to a range of qualified entities beyond standard categories, but applicants would need to confirm eligibility specifics in the full RFA text. Overall, the opportunity is geared toward applicants with strong technical expertise in watershed modeling, the ability to produce defensible scenario analyses, and the capacity to work collaboratively with EPA and Chesapeake Bay governance partners to deliver model applications that directly support TMDL planning and climate-informed restoration decision-making.Apply for EPA R3 CBP 23 07
