Returning as an in-person event after being held virtually due to the pandemic, the 32nd Annual Nonpoint Source (NPS) Conference was held April 27-28 in Woodstock, Vermont.

Opening remarks session on 4/27/2022 of the 2022 Annual NPS Conference in Woodstock, VT.


Since 1990, NEIWPCC, in partnership with its member states, has been coordinating the Annual Nonpoint Source (NPS) Conference. The Annual NPS Conference is the premier forum in the Northeast for sharing information and improving communication on NPS pollution issues and projects.

The conference theme in 2022 was “Clean Water Act: Past and Future” to celebrate the 50th anniversary of the Clean Water Act in 2022. Sessions included financing NPS projects, partnership building and community engagement, structural and non-structural BMPs, and other pivotal topics for the Northeast region and NPS community. For more specific information on our sessions, you can reference the Conference Agenda (download) and the presentation Abstracts Packet 2022. If you would like to review the presentation materials, please contact Lynn Porta.

NEIWPCC is committed to providing an event that keeps all participants as safe as possible and promotes the well-being of our community. NEIWPCC requires all individuals who participate in the Annual NPS Conference to be fully vaccinated to attend.

  • Following the U.S. Centers for Disease Control and Prevention’s (CDC’s) guidance, people are considered “fully vaccinated” either 2 weeks after they receive their second dose in a 2-dose series, such as the Pfizer or Moderna vaccines, or 2 weeks after they receive their single-dose vaccine, such as Johnson & Johnson’s Janssen vaccine.
  • As new guidance regarding vaccine recommendations is updated by the CDC to include booster doses in the future, participants may be required to provide proof they have received such doses.

In addition, all attendees must adhere to all NPS Conference safety measures. The NPS Conference will operate according to the prevailing federal, state, county, and city laws, regulations, recommendations, and guidelines, as well as venue-specific regulations for the Woodstock Inn, as they are in effect over the NPS Conference dates (including but not limited to face mask requirements, social distancing, etc.).

To ensure safety, we will not be accepting on-site registrations.

We will continue to revise our procedures as needed to reflect the current state of the pandemic.
