Who is affected and how:

• EPA and federal implementers: EPA would interpret and apply the revised statutory language and may need to issue guidance, revise grant solicitations, or update program manuals depending on the substance of the replacement text.

• State and local governments, estuary management organizations, and nonprofit partners: These groups implement projects under the National Estuary Program and could see changes in program rules that affect grant eligibility, application requirements, allowable activities, or reporting. Without the replacement text, the change could be merely clarifying (low practical impact) or could alter who qualifies or how funds may be used (moderate-to-significant impact).

• Coastal and estuarine communities and stakeholders: Community outcomes—such as restoration, water quality improvements, and habitat protection—could be indirectly affected if the statutory change shifts program priorities or funding administration.

• Environmental advocates and technical partners: May need to adjust recommendations and project designs if the statutory change modifies program goals, priorities, or compliance requirements.

Uncertainty and likely scenarios:

• Technical/clarifying amendment: If the replacement text is clarifying language, practical impacts will be small and limited to legal interpretation.
• Substantive policy change: If the replacement text changes eligibility, priorities, or administrative requirements, affected entities may need to change project plans, reapply under new criteria, or adjust budgets to meet new requirements.

Overall, the magnitude of impact depends entirely on the replacement language not provided in the excerpt. The amendment itself signals a legal change that merits monitoring by program participants and EPA implementers.
