The Environmental Council of the States (ECOS), a nonprofit, nonpartisan national association of state and territorial environmental commissioners, is the host organization for ITRC headquarters.

ECOS Resolutions to Promote ITRC
In an August 2003 resolution, ECOS praised ITRC achievements, supported the integration of ITRC into the ERIS corporation, and pledged its support for the continued success of the ITRC mission and promotion of ITRC documents, training, and expertise. At its annual meeting in August 2001, ECOS passed resolutions urging states and federal agencies to expand their support of ITRC:

• Supporting State Participation for Interstate Technology and Regulatory Cooperation
• Encouraging Federal Support for Interstate Technology and Regulatory Cooperation
