*OEI served as the corporate fiscal sponsor for the Onondaga Earth Corps (OEC) beginning in May 2011, building OEC’s capacity to grow into an independent nonprofit in 2016. OEI’s mission is supported by OEC’s mission to empower youth to be active participants in creating positive change for their communities and the environment, specifically by fostering outreach and education to develop an informed public, promote environmental ethics and build an environmentally conscious citizenry.

OEI served as fiscal sponsor to the Partnership for Onondaga Creek (POC) from December 2010 through its dissolution in November 2018 upon celebrating 17 years of effective and important environmental justice work. OEI and POC’s missions are aligned through commitment, education and positive action toward the revitalization and protection of our water resources.

As a 501(c)(3) organization, OEI receives contributions, including grants, on behalf of the sponsored groups; administers these funds; and performs the necessary grant management tasks, including records management, accounting of expenditures, financial reporting, progress reporting, and managing the related human resources and payroll duties. OEI also provides general nonprofit management oversight while helping these groups build capacity to transition to independence. OEI has managed over $1 million awarded through over 30 grants and contracts on behalf of its fiscal sponsorees.


** OEI understands the government-to-government relationship between the Onondaga Nation and USEPA and is honored to support the consultation and cooperation between these two governments.
