This Implementation Agreement is expected to continue to evolve during the life of the Acts. Maintenance of the Implementation Agreement is the responsibility of the Partners Working Group. BLM will prepare draft revisions based on processes put into place with the Executive Committee since the previous version was approved, SNPLMA Division recommendations, Executive Committee decisions regarding changes in policy, comments and suggestions from Federal managers and SNPLMA Subgroup members, and Working Group recommendations. The BLM will distribute the draft revisions for review and comment by the subgroups and others involved in implementation of the Acts. A final draft approved by the Working Group will be submitted to the Executive Committee. All proposed changes must be approved by the Executive Committee before they take effect except those effective as of the date of prior Executive Committee decisions.
