commenced commercial operation on the first date on which the unit resumes operation.

notice, contact Robert Miller at miller.robertl@epa.gov or 202.343.9077, or contact your local, State, or EPA 

Regional Acid Rain or CAIR contact, as appropriate. You may also call U.S. EPA's Acid Rain Hotline at (202) 

343-9620.

Any reference in these instructions to the Designated Representative means the Acid Rain Designated 

Representative and/or CAIR Designated Representative, as applicable. Any reference to the Alternate 

Designated Representative means the Alternate Acid Rain Designated Representative and/or the Alternate 

CAIR Designated Representative, as applicable. The Acid Rain Designated Representative and the CAIR 

Designated Representative for a facility (source) must be the same individual, and the Alternate Acid Rain 

Designated Representative and the Alternate CAIR Designated Representative for a facility (source) must be 

the same individual.

Submission Deadline: For units subject only to CAIR, 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). For 

units subject only to the Acid Rain Program, submit the form by December 31 of the first year the unit is to be 

exempt. If the unit is subject to the Acid Rain Program and to CAIR, 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 1Enter the facility name and state where the unit is located, the ORIS/Plant Code for the facility, and 

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 4 or 5 digit 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) 586-4258 or 

(202) 586-2402. 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, 

contact Laurel DeSantis at desantis.laurel@epa.gov or (202) 343-9191.

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 Acid Rain Program, 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 appropriate special provisions.

STEP 6 Read the appropriate certification statements, sign, and date.

For units subject only to the Acid Rain Program, if no designated representative has been authorized, a 

certifying official for each owner of the unit must read the certification at STEP 6 labeled "for certifying officials 

of Acid Rain affected units only,@ 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.
