Final Amendments to Delegation of Authority Provisions in the Prevention of Significant Deterioration Permitting Program

This final rule will amend the New Source Review Prevention of Significant Deterioration (PSD) program to allow EPA to delegate administration of the program to interested and qualified tribal agencies. This action does not impose new requirements but will allow the EPA to treat tribes in the same manner as state and local governments for purposes of PSD permitting.
