The Connecticut Department of Energy and Environmental Protection (DEEP) is accepting proposals for Clean Water Section 319 matching grants.  Section 319 of the Federal Clean Water Act (Section 319) is a Federal program to control nonpoint sources (NPS) of water pollution.  Connecticut receives funds for matching grants 319 that can be passed on to communities, local conservation groups, and other organizations for NPS projects, plans, and statewide efforts.  Proposals may be submitted by any interested public or private organization.
The U.S. Environmental Protection Agency (EPA) defines NPS pollution as pollution that is “caused by diffuse sources that are not regulated as point sources, and are normally associated with precipitation and runoff from the land.”  Common NPS pollutants include:  bacteria, nutrients, sediment, salt, petroleum products, heavy metals, pesticides, and debris.  These pollutants are typically carried by stormwater runoff into streams, lakes, and estuaries from diffuse land use and other activities that are not regulated as point source discharges (“end of pipe”).  Projects intended to meet mandated conditions of stormwater permits are not eligible for Section 319 grants.  However, proposals that provide stormwater mitigation above and beyond permit requirements may be considered.
The Section 319 grant program primarily focuses on addressing NPS impacts in water bodies listed as impaired in Chapter 3 of the “2014 State of Connecticut Integrated Water Quality Report" (IWQR).  This list of water bodies is also known as “Connecticut Water Bodies Not Meeting Water Quality Standards” or Clean Water Act Section 303(d) list of impaired waters.  In 2016 Section 319 grants will prioritize projects that aim to restore waters on Connecticut Interim NPS Priority Watershed List to meet water quality standards.  A list of these water bodies can be found in Appendix C of the Connecticut Nonpoint Source Management Program Plan 2014.  Appendix C includes the impaired waters from the IWQR, and also includes water bodies threatened by NPS but not listed as impaired.  Water bodies listed as threatened are eligible for Section 319 grants that focus on protective measures such as creation of 9 element Watershed Based Plans.  DEEP will prioritize projects to restore and protect water bodies listed in Appendix C, but other Connecticut water bodies may be considered for Section 319 grants.
Project Priorities 
Watershed Based Plan Implementation Projects
Project priorities  will continue to stress implementation projects in watersheds that have approved Watershed Based Plans (WBP) that lead to actual pollutant load reductions.  Implementation projects should have a clear connection to the management goals and objectives of the WBP and show progress towards attaining water quality goals.  Applicants are strongly urged to consult with DEEP Watershed Managers to ensure their proposals are consistent with approved WBPs.
Implementation Projects Not Associated with WBPs
DEEP may consider implementation projects that are not connected to an existing WBP.  Applicants must be able to document benefits toward pollutant load reduction and attainment of water quality standards. For implementation projects not covered under a WBP, applicants should consider including development of a WBP as part of the project proposal where practical.
Watershed Based Plan Development 
DEEP will also consider projects that develop WBPs.  DEEP will consider funding WBPs for watersheds with impaired water bodies as well as healthy watersheds.  EPA has provided detailed guidance on WBP structure and content.  See requirements for Watershed Based Plans.  For projects in unimpaired and healthy waters, or when the impairment is not specific to a pollutant, or when addressing a small scale water quality problem, DEEP will consider alternative watershed based plans.

Implementation of Non Structural Best Management Practices
DEEP intends to continue to support these lower priority activities as available funding allows; these projects will rank higher when they are paired with implementation projects.  If projects can provide quantifiable pollutant load reductions, this will improve their likelihood for funding.

  • Monitoring, Assessment, and Trackdown Projects:  DEEP will consider using Section 319 funds to support monitoring, modeling, assessment, and trackdown studies relevant to the control of nonpoint source pollution.  Approved Quality Assurance Project Plans (QAPP) may be required for these types of projects.
  • Watershed or Statewide Education and Outreach Projects:  Demonstration, technical assistance, public outreach and education, and watershed management projects may also be funded.  Pollution prevention outreach activities that promote better pet waste, lawncare, or reduce the pollution in runoff from impervious surfaces fit in this category. Projects that can demonstrate water quality improvements or have technical transfer capability rank higher.
  • Land Use Management Projects:  These projects may include municipal land use evaluations and modification to existing regulatory programs that promote green infrastructure and low impact development techniques, integrated pest and/or nutrient management planning, site plan reviews, education for municipal officials or land use boards, and other activities that benefit nonpoint source pollution control.
