Can a single non-profit submission that has support and or endorsements from state agencies and a Tribe submit an application? And would this submission compete with other Washington submitters?

Non-profits are not eligible entities in of themselves, so they cannot submit an application under our program (as the lead entity, anyways). Nonprofits can partner with an eligible entity, such as a state agency, a Tribe, a US territory, or an entity that has status as an instrumentality of a state or Tribe (aka, a university). Whatever eligible entity submits the application, in partnership with the non-profit organization, would be in competition with any other applications submitted from that same government. So, in your example, if the Washington Department of Ecology partnered with the nonprofit, it would be in direct competition with any other applications from a Washington state entity (including an instrumentality, such as WSU).
