SECTiON 0- DEFINITIONS

In the Regulations, defined words are CAPrrAUzED.

In these Regulations, unless the context otherwise requires:

“AcT” means the Clean Ar Act, as amended, 42 U.S.C. 7401, et seq.

“AcTuAL

UNIT,

EMISSIONS” means the actual rate of EMISSIONS of a pollutant from an EMISSION

as determined in accordance with the following:

(a) In general, ACTuAL EMISSIONS as of a particular date shall equal the average

rate, in tons per year, at which the EMISSION UNIT actually emitted the pollutant

during the two (2) year period which precedes the particular date and which is

the

representative of normal source operation. The CoNTRoL OFFICER shall allow

use of a different time period upon determination that it is more

representative of normal source operation. AcTuAL EMIsSIONs shall be

calculated using the EMISSION UNIT’S actual operating hours, production rates,

and types of materials processed, stored, or combusted during the selected

time period.

(b) The CONTROL OFFICER may presume that source specific ALLOWABLE

EMISSIONS for an EMISSIONS UNIT are equivalent to the ACTUAL EMISSIONS of

such EMISSION UNIT.

(c) For any EMISSION UNIT, except as specified in (d), which has not begun normal

operations on the particular date, AcTuAL EMISSIONS shall equal the PoTEr.m6L

TO EMIT of such EMISSION UNIT on that date.

(d) For an ELECTRIC UTIuW STEAM GENERATING UNIT (other than a new unit or the

replacement of an existing unit) ACTUAL EMISSIONS of the unit following the

physical or operational change shall equal the representative ActuAL

EMISSIONS of the unit, provided the source owner or operator maintains and

submits to the CoNTRoL OFFICER on an annual basis for a period of five (5)

years from the date the unit resumes regular operation, information

demonstrating that the physical or operational change did not result in an

EMISSIONS increase. A longer period, not to exceed ten (10) years, may be

representative

required by the CONTROL OFFICER if he determines such a period to be more of normal source post-change operations.

(d) An increase or decrease in Ac1uL EMissioNs of sulfur dioxide, PM10,or

nitrogen oxides which occurs before the applicable minor source BASELINE

Date is creditable only if it is required to be considered in calculating the

amount of maximum allowable increases remaining available.

(e) An increase in AcTuAL EMISSIONS is creditable only to the extent that the new

level of AcTuAL. EMISSIONS exceeds the old level.

(f) A decrease in AcTuAL. EMISSIONS is creditable only to the extent that

(1) The old level of AcTuAL EMISSIONS or the old level of AllowABLE

EMISSIONS, whichever is lower, exceeds the new level of AcTuAL

EMISSIONS;

(h) The following examples are provided on how to calculate a NET EMISSIONS

INCREASE (NEI):

Example I

Given Information:
I D/i3/3

Increase in Production MODIFICATION -No change in Process

Source’s existing P0TEN11AL TO EMrr (PTE): 60 tons/year

Source’s new PoTENTIAL TO EMrn 80 tons/year

Source’s existing AcTuAL EMissioNs (AE): 50 tons/year

NEI = (new PTE) — (existing AE) -

NEI= 80-50

NEI = 30 tons per year

• In the situation of identical process with an increase in production

MoDIFIcATIoN, the existing AcTuAL EMissioNs and the new PoTENTiAL

TO EMIT must be calculated using the same EMISSION factors. The

existing AcTuAL. EMissioNs are based on actual, production over the

appropriate period prior to application submission.

Example 2

Given Information:

New Process MoDIFIcATIoN

Source’s existing POTENTIAL TO EMIT (PTE): 60 tons/year

Source’s new PoTENTIAL. ToEMrr; 65 tons/year

Source’s existing AcTuAL EMIssIoNs (AE): 50 tons/year

NEI = (new PTE) — (existing AE)

NEI=65-50

NEI= l5tonsperyear

• In the situation of new process MoDIFIcATION, the existing AcTuAL

EMissioNs and the new POTENTIAL TO EMIT must be calculated using

the most recently updated EMISSION factors. The existing AcTuAL

EMISSIONS are based on actual production over the appropriate period
