Final Rules ==================== -(c) Particulate emissions from the combustion of

fuel for indirect heating from all facilities receiving permits to construct on or after September 21, 1983 shall be limited by 326 lAC 6-2-4.

(d) If any limitation established by this rule (326 lAC 6-2) is inconsistent with applicable limitations con­tained in 326 lAC 6-1, then the limitations contained in 326 lAC 6-1 prevail.

(e) If any limitation established by this rule (326 lAC 6-2) is inconsistent with applicable limitations con­tained in 326 lAC 12, New Source Performance Stan­dards, then the limitations contained in 326 lAC 12 prevail.

(f) If any limitation established by this rule (326 lAC 6-2) is inconsistent with a limitation contained in a facility's construction or operation permit as issued pur­suant to 326 lAC 2, Permit Review Regulations, then the limitations contained in the source's current per­mits prevail.

(g) If any limitation established by this rule (326 lAC 6-2) is inconsistent with a limitation required by 326 lAC 2, Permit Review Regulations, to prevent a violation of the ambient air quality standards set forth in 326 lAC 1-4, then the limitations required by 326 lAC 2 prevail.

(h) The addition of a new facility at a source does not affect the limitations of the existing facilities unless such changes in the limitations are required by the provisions of 326 lAC 2 or 326 lAC 6-1. (Air Pollution Control Board; 8~6 lAC 6-~-1;filed Mar 10,1988,1:20 pm)

Sec. 2. (a) Particulate emissions from existing indirect heating facilities located in the specified coun­ties shall be limited by the following equation:

For Qless than 10 mmBtulhr, Pt shall not exceed 0.6. For Q greater than or equal to 10,000 mmBtulhr, Pt shall not exceed 0.2. Figure 1may be used to estimate ­allowable emissions.

(b) The emission limitations for those indirect heat­ -ing facilities which were existing and in operation on or before June 8, 1972, shall be calculated using the equa­tion contained in subsection (a) of this section where: Q shall reflect the total source capacity on June 8, 1972. ­The resulting Pt is the emission limitation for each facility existing on that date and will not be affected by the addition of any subsequent facility. The particulate -emissions from all of the facilities which were in exis­tence on June 8, 1972, may be allocated in any way among these facilities provided that they will not result ­in a significantly greater air quality impact level at any receptor than that which would result if the particulate emissions from each of these facilities were limited to Pt; and provided that the emission limitations for each ­facility are specified in its operation pennit. Significant impact levels are defined in 326 lAC 2.-3(d).

....... (e) The emission limitations for those indirect heat· ,_'

ing facilities which began operation after June 8, 1972, and before September 21, 1983, and those facilities which receive permits to construct prior September 21, 1983 shall be calculated using the equation contained in subsection (a) of this section where: Q includes the capacity for the facility in question and the capacities for those facilities which were previously constructed or received prior permits to construct. The limitations for all previously permitted facilities do not change. The Qand Pt for each facility at a source which begins operation or receives a construction permit during this time period will be different.

Pt = Pounds ofparticulate matter emitted per million Btu heat input Ob/mmBtu).

Q = 'Ibtal source maximum operating capacity rat ­• ing in million Btu per hour (mmBtulhr) heat

The maximum operating capacity rating is defined as the maximum capacity at which the facility is operated or the nameplate capacity, whichever is specified in the facility's operation permit application, except when some lower capacity is contained in the facility's operation permit; in which case, the capacity specified in the operation permit shall be used.

N = Number of stacks in fuel burning operation.

a •. Plume rise factor which is used to make allow­ance for less than theoretical plume rise. The value 0.67 shall be used for Qless than or equal to 1,000 mmBtulhr heat input. The value 0.8 shall be used for Q greater than 1,000 mmBtulhr heat input.

h = Stack height in feet. If a number of stacks of different heights exist, the average stack height to represent "N" stacks shall be calculated by weighing each stack height with its particulate matter emission rate as follows:

Where:

pa = the actual controlled emission rate in IblmmBtu using the emission factor from AP-42 or stack test data. Stacks constructed after January 1, 1971, shall be credited with GEP' stack height only. GEP stack height shall be calculated as specified in 326 lAC 1-7.

(b) The emission limitations for those indirect heat­ing facilities which were existing and in operation on or before June 8, 1972, shall be calculated using the equa­tion contained in subseetion (a) ofthis section where: Q, N, and h shall include the parameters for all facilities in operation on June 8, 1972. The resulting Pt is the emis­

sion limitation for each facility existing on that date and will not be aff'ected by the addition of any subsequent facility. The particulate emissions from all of the facili­ties which were in existence on June 8, 1972, may be allocated in any way among these facilities provided that they will not result in a significantly greater air quality impact level at any receptor than that which would result if the particulate emissions from each of these facilities were limited to Pt; and provided that the emission limitations for each facility are specified in its operation permit. Significant impact levels are defined in 326 lAC 2-.'3-2(d).

(c) The emission limitations for those indirect heat­ing facilities which began operation after June 8, 1972, and before September 21, 1983, and those facilities which receive permits to construct prior to September 21, 1983, shall be calculated using the equation con­tained in subsection (a) oithis section where: Q, N, and h shall include the parameters for the facility in ques­tion and for those facilities which were previously con­structed or received prior permits to construct. The limitations for all previously permitted facilities do not change. The Q, N, h, and Pt for each facility at a source which begins operation or receives a construction per­mit during this time period will be different.

(d) Particulate emissions from all facilities used for indirect heating purposes which were existing and in operation on or before June 8, 1972, shall in no case exceed 0.8 Ib/mmBtu heat inl'ut.

(e) Particulate emissions from any facility used for indirect heating purposes which has 250 mmBtulhr heat input or less and which began operation after June 8,1972, shall in no case exceed O.6lb/mmBtu heat input. (Air Pollu.tion Control Board; 3fl6 lAC 6-fl-3;filed Mar 10, 1988, l:flO pm)

-is defined as the maximum capacity at which the facility is operated or the nameplate capacity, whichever is specified in the facility's permit application, except when some lower capacity is contained in the facility's operation permit; in which case, the capacity specified in the opera­tion permit shall be used.

For Q less than 10 mmBtulhr, Pt shall not exceed 0.6. For Q greater than or equal to 10,000 mmBtuIhr, Pt shall not exceed 0.1, Figure 2 may be used to estimate allowable emissions.

(b) As each new indirect heating facility is added to a plant Q will increase. As a result, the emission limita- .' tion for each progressively newer facility will be more stringent until the total plant capacity reaches 10,000 mmBtulhr after which the emission limit for each newer facility will be 0.1 Ib/mmBtu heat input. The rated capacities for facilities regulated by 326 lAC 12, New Source Performance Standards, shall be included when calculating Q for subsequent facilities. -
