State Specific Comments:

Alaska* The Alaska Dept of Environmental Conservation (DEC) began a phased 3 year program to assume the NPDES permitting authority on 10/31/2008. As of 9/30/12, DEC is responsible for all facilities in Alaska except for the following: outer continental shelf facilities, 301(h) facilities (~11), tribal facilities (~4), 1 federal facility, and oil and gas facilities. On Oct 31, 2012, DEC will assume authority for oil and gas facilities.
Oklahoma** Partial Program. It has not been authorized to issue permits for activities associated with oil and gas exploration, drilling, operations, and pipelines, and for CAFOs and certain other discharges from agriculture. EPA is the permitting authority for those facilities since it is not in Oklahoma DEQ's jurisdiction. All parts of the program within jurisdiction of Oklahoma DEQ are authorized.
Texas*** Partial Program. It has not been authorized to issue permits for activities associated with the exploration, development, or production of oil or gas or geothermal resources, including transportation of crude oil or natural gas by pipeline. EPA is the permitting authority for those facilities since it is not in Texas Commission on Environmental Quality's jurisdiction. All parts of the program within jurisdiction of the Texas Commission on Environmental Quality are authorized.
