The State of Utah has committed to revise its stack height regulations should EPA complete rulemaking to respond to the decision in NRDC v. Thomas, 838 F. 2d 1224 (D.C. Cir. 1988). In a letter to Douglas M. Skie, EPA, dated May 27, 1988, F. Burnell Cordner, Director, Bureau of Air Quality, stated:
* * * We are submitting this letter to allow EPA to continue to process our current SIP submittal with the understanding that if the EPA's response to the NRDC remand modifies the July 8, 1985 regulations, the EPA will notify the State of the rules that must be changed to comply with the EPA's modified requirements. The State of Utah agrees to process appropriate changes.
