I received a call from a permit engineer with the Arizona Dept.
of  Environmental Quality (ADEQ) concerning the issue of notification of  mechanical activities at C/S 2  Flagstaff and a mandatory 7 day wating period  for agency review and approval.
Due to the urgency of the C/S 2 work being  performed, I had written a notification to the agency friday evening  requesting approval to initiate the activities detailed in the scope of work  which was included with the letter.
On Monday, the engineer called and said  that he had read the letter and had no problems with the activity proceeding  at the C/S.
After we had discussed this issue at some length, I posed the  question to him of whether it was necessary to notify the agency of  mechanical and maintenace activities which  will not impact or change a  combustion units throughput, fuel use, emissions, horsepower, or cause a  change in design.
After some discussions I informed him that Transwestern  will probably inundate the agency with notification letters, he stated that  as long as the engines operating parameters would not change, ( horsepower,  emissions, throughput, fuel use etc), and the burden of responsibility will  rest on Transwestern to ensure that no permit conditions are violated, he  stated that we may proceed with these types of activities in Arizona without  any notification to the agency.
The only hitch being, that when Transwestern does a major mechanical  activity, which would cost more than  25-30% of the cost of replacing a unit,  that we provide them a courtesy notification.
I told them we would apprise  them of such an activity.....
