The Moving Ahead for Progress in the 21st Century Act MAP-21 established the Surface Transportation Project Delivery Program that allows a State to assume FHWA's environmental responsibilities for environmental review consultation and compliance under the National Environmental Policy Act NEPA for Federal highway projects. When a State assumes these Federal responsibilities the State becomes solely responsible and liable for carrying out the responsibilities it has assumed in lieu of FHWA. This program mandates annual audits during each of the first 4 years of State participation to ensure compliance with program requirements. This is the fourth audit of the responsibilities assigned to the Arizona Department of Transportation ADOT under the Surface Transportation Project Delivery Program NEPA Assignment Program. This notice announces and solicits comments on the fourth audit report for ADOT.
