Under the CEQ NEPA Implementing Procedures (40 CFR §1501.6, Cooperating agencies), upon request of a lead agency preparing an EIS, any other Federal agency which has jurisdiction by law shall be a cooperating agency. In addition, any other Federal agency which has special expertise with respect to any environmental issue that should be addressed in the EIS may be a cooperating agency upon request of the lead agency. This compilation of Federal and Federal-State agencies with jurisdiction by law or special expertise on environmental quality issues was previously published as Appendix II to the CEQ NEPA Implementing Procedures.
