PAEL Rescission Guidance

To have a PAEL rescinded, the stationary source's Total Potential to Emit (PTE) must be less than 40 tons per year (tpy) of NOx.

The owner or operator of any stationary source that currently holds a PAEL and can demonstrate the source does not have potential NOx emissions approaching 40 tpy without limits may request the department rescind its PAEL by taking one of the following steps:

Write a Rescission Request letter to: Supervisor, Title V Air Permit Program, 555 Cordova Street, Anchorage, Alaska 99501. Include a list of the current installed diesel electric generators at the stationary source. Show the total engine brake horsepower or electrical generating capacity and the PTE for all units combined. Include a list of all other fuel burning equipment, such as heaters, combustion turbines and boilers (if any). Show the total capacity of combustion turbines, heaters and boilers and their PTE. The letter should request the Department to rescind the current stationary source PAEL. The letter must be signed and certified by the Stationary Source's responsible official as required by 18 AAC 50.205;

For emergency backup power plants, write a letter to: Supervisor, Title V Air Permit Program, 555 Cordova Street, Anchorage, Alaska 99501. Include a list of the current installed diesel electric generators at the stationary source. List the total rated capacity of the engines at the stationary source. State that the diesel electric generators are strictly for emergency use if the normal power supply is interrupted. Include a list of all other fuel burning equipment, such as heaters, combustion turbines and boilers (if any). Show the total capacity of combustion turbines, heaters and boilers. The letter must request that the Department rescind the current stationary source PAEL. The letter must be signed and certified by the Stationary Source's responsible official as required by 18 AAC 50.205;

For a source with both emergency and non-emergency generators, write a letter to: Supervisor, Title V Air Permit Program, 555 Cordova Street, Anchorage, Alaska 99501. Include a list of the current installed diesel electric generators at the stationary source. The letter must state the total rated capacity of the emergency engines and total rated capacity of non-emergency engines at the stationary source. Designate the specific use for each generator (i.e. emergency backup or power generation). Include a list of all other fuel burning equipment, such as heaters, combustion turbines and boilers (if any). Show the total capacity of combustion turbines, heaters and boilers. Attach emission calculations determined in accord with the method listed in item C of the PAEL diesel generator application. The letter must request that the Department rescind the current PAEL for the stationary source. The letter must be signed and certified by the stationary source's responsible official as required by 18 AAC 50.205.

Note: The Department does not automatically rescind PAELS based upon the October 2004 rule change and endorsement of EPA policy. The owner or operator of the stationary source must initiate the request to rescind a PAEL. All PAELs currently in effect will remain in effect until the department rescinds the PAEL.
