Instructions for Common Stack Allowance

Deduction Form (OPTIONAL)

The Common Stack Allowance Deduction Form may be used to indicate the number of allowances to

be deducted for compliance from each unit that shares a common stack or pipe. If you choose to use

this form, it must be submitted with the Compliance Certification Report by Novermber 30 of the

calendar year that includes the control period.

Step 1 Enter the calendar year that includes the control period for which you are certifying compliance, Plant Name, State, and ORIS Code.

Step 2 When two or more NOx Budget units share a common emission stack and have emissions that are not individually monitored, you have the option of identifying the fraction of total allowances to be deducted from each unit's NOx Allowance Tracking System (NATS)

Account, unless the units are using an approved apportionment method under 40 CFR Part

75. (Where an approved special apportionment method is used, the deduction from each unit

is already established.) When using this option, enter the NATS Account Number, Fraction of

Total Allowances to be Deducted, and the Common Stack Identification Number for each unit

sharing a common stack. If you do not indicate otherwise, an equal percentage of allowances

 will be deducted from each unit's account.

EXAMPLE 1: Four units emit through a common stack (ID No. CS10). The total annual

emissions from stack CS10 = 10,000 tons. Leaving Step 2 blank results in the deduction of

2500 allowances from each of the four units.

EXAMPLE 2: The same four units emit the same annual emissions as in Example 1. The

designated representative wants 60% of the allowances deducted from unit 1, 40% from unit

4, and 0 from units 2 and 3. The step is completed as illustrated: Fraction of Total

NATS Account Number Allowances to be Deducted Common Stack Number

00 0 0 0 1 0 0 0 0 0 1 0 . 6 0 0 0 0 0 0 CS1 0

00 0 0 0 1 0 0 0 0 0 4 0 . 4 0 0 0 0 0 0 CS1 0

complete and review the collection of information; and transmit or otherwise disclose the information. An

agency may not conduct or sponsor, and a person is not required to respond to, a collection of information

unless it displays a currently valid OMB control number.
