This Supplemental Notice advises the public that the Bureau of Indian Affairs (BIA) as Lead Agency will be revising the Draft Environmental Impact Statement for the Osage County Oil and Gas program.

This Supplemental Notice announces an additional public scoping meeting to identify potential issues and content for inclusion in the EIS. The BIA solicits written comments and oral comments at the public meeting on the range of reasonable alternatives for implementing the proposed action and issues to be addressed in the revised Draft EIS, such as information regarding the level of oil and gas development in Osage County or possible mitigation measures for environmental and socioeconomic impacts of that development.
