Instructions for the Retired Unit Exemption Notice
Please type or print. If you have any questions regarding the submission of the Retired Unit Exemption
notice, please send an email to [email protected], or contact your local, State, or EPA Regional
contact for the Acid Rain Program (ARP), Cross-State Air Pollution Rule (CSAPR), or Texas SO2 Trading
Program (TXSO2), as appropriate. You may also call EPA's Acid Rain Hotline at (202) 343- 9620.
Submission Deadline: For units subject only to the ARP, submit the Retired Unit Exemption notice by
December 31 of the first year the unit is to be exempt. For units subject to the CSAPR or TXSO2 programs
(including units also subject to the ARP), submit the Retired Unit Exemption notice no later than 30 days
after the date the unit is permanently retired (i.e., within 30 days of the date entered at STEP 3).
STEP 1 Enter the plant name and state where the unit is located, the Plant Code for the facility, and the
Unit ID for the unit, consistent with the data listed on the most current Certificate of Representation
for the facility. A Plant Code is a number assigned by the Department of Energy’s (DOE) Energy
Information Administration (EIA) to facilities that generate electricity. For older facilities, "Plant
Code" is synonymous with "ORISPL" and "Facility" codes. If the facility generates electricity but
no Plant Code has been assigned, or if there is uncertainty regarding what the Plant Code is,
contact EIA at (202) 586-1029. For facilities that do not produce electricity, use the facility
identifier assigned by EPA (beginning with "88"). If the facility does not produce electricity and
has not been assigned a facility identifier, please send an email to [email protected].
STEP 2 Identify the programs to which the unit is subject.
STEP 3 Enter the date on which the unit was (or will be) permanently retired.
STEP 4 If the unit is subject to the ARP, identify the first full calendar year in which the unit meets (or will
meet) the requirements of 40 CFR 72.8(d).
STEP 5 Read the applicable special provisions.
STEP 6 Read the statement of compliance and the applicable certification statements, sign, and date. For
units subject only to the ARP, if no designated representative has been authorized, a certifying
official for each owner of the unit must read the certification at STEP 6 labeled " certifying officials
of units subject only to the Acid Rain Program”, enter his or her name, title, name of the owner
company for which he or she is the certifying official, phone number, email address, and then sign
and date. A certifying official is not required to submit a Certificate of Representation. If there is
more than one owner of a unit for which no designated representative has been authorized, each
owner of the unit must have a certifying official sign the appropriate certification at STEP 6.
Submit the original Retired Unit Exemption notice to the title V permitting authority for the facility, and mail
a copy to one of the following mailing addresses (please note the different zip codes):
