Section 117(e)(1)(A) of the Clean Water Act authorizes EPA to award Chesapeake Bay Implementation Grants (CBIG) to State/Signatory Jurisdictions. The Implementation Grants enable states the lie in the Chesapeake Bay watershed to provide resources for programs that improve water quality in the Chesapeake Bay Watershed. Maryland focuses these funds on initiatives that reduce nonpoint source nutrient and sediment pollution. In order to ensure that CBIG funds are spent effectively, especially in light of the State’s 2 Year Milestone commitments, Maryland has chosen to narrow the types of project/programs to the following four areas:

  • Technical Assistance & Implementation
  • Innovation/Contingency Development
  • Monitoring and Evaluation
  • Tracking and Reporting


CBIG grants are three years with individual projects generally ranging from 10-12 months renewable each year. Total funding for CBIG is about $ 4.6 Million annually. This total includes both federal funds and non-federal match. Funded projects are in the range of $25,000 to $400,000. Under each separate contract, funded projects are reimbursed for funds expended once work is completed.


Available Funds/Resources available under CBIG:
