326 IAC 10-3-3 - Emission limits

Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11

Affected: IC 13-15; IC 13-17

Sec. 3.

(a) After May 31, 2004, an owner or operator of any Portland cement kiln subject to this rule shall not operate the kiln during the ozone control period of each year unless the owner or operator complies with one (1) of the following:

(1) Operation of the kiln with one (1) of the following:

(A) Low-NO_x burners.

(B) Mid-kiln firing.

(2) A limit on the amount of NO_x emitted when averaged over the ozone control period as follows:

(A) For long wet kilns, six (6) pounds of NO_x per ton of clinker produced.

(B) For long dry kilns, five and one-tenth (5.1) pounds of NO_x per ton of clinker produced.

(C) For preheater kilns, three and eight-tenths (3.8) pounds of NO_x per ton of clinker produced.

(D) For precalciner and combined preheater and precalciner kilns, two and eight-tenths (2.8) pounds of NO_x per ton of clinker produced.

(3) Installation and use of alternative control techniques that may include kiln system modifications, such as conversions to semi-dry precalciner kiln processing, subject to department and U.S. EPA approval that achieve a thirty percent (30%) emissions decrease from baseline ozone control period emissions. Baseline emissions must be the average of the sum of ozone control period emissions for the two (2) highest emitting years from 1995 through 2000 determined in accordance with subsection (d)(1).

(b) The owner or operator of a Portland cement kiln proposing to install and use an alternative control technique under subsection (a)(3) shall submit the proposed alternative control technique and calculation of baseline emissions with supporting documentation to the department and U.S. EPA for approval by May 1, 2003. The department shall include the approved plan with emission limitations in the source's operating permit.

(c) The owner or operator of any affected boiler subject to this rule shall limit NO_x emissions to seventeen-hundredths (0.17) pound of NO_x per million Btus (lb/MMBtu) of heat input averaged over the ozone control period and ensure that greater than fifty percent (50%) of the heat input is derived from blast furnace gas averaged over an ozone control period.

(d) The owner or operator of an affected boiler shall submit to the department a compliance plan for approval by the department and U.S. EPA in accordance with subsection (e) and including the following:

(1) Baseline stack test data, or proposed testing, for establishment of fuel specific emission factors, or the emission factors for the type of boiler from the Compilation of Air Pollutant Emission Factors (AP-42), as defined at 326 IAC 1-1-3.5, for each fuel to be combusted. The fuel specific emission factor must be developed from representative emissions testing, pursuant to 40 CFR 60, Appendix A, Method 7*, 7A*, 7C*, 7D*, or 7E*, or 40 CFR 75 *, based on a range of typical operating conditions. The owner or operator must:

(A) establish that these operating conditions are representative, subject to approval by the department; and

(B) certify that the emissions testing is being conducted under representative conditions.

(2) Anticipated fuel usage and combination of fuels.

(3) If desired by the source, a proposal for averaging the emission limit and fuel allocation among commonly owned units, including the proposed methodology for determining compliance.

(e) The owner or operator of an affected boiler shall submit to the department the compliance plan required in subsection (d) by the following date, as applicable:

(1) By May 1, 2003, for an affected boiler that became subject to the rule prior to May 1, 2003.

(2) Within sixty (60) days of the date the affected boiler becomes subject to this rule, for an affected boiler that becomes subject to the rule after May 1, 2003.

(f) Baseline ozone control period emissions must be determined using one (1) of the following methods:

(1) For kilns, the average of the emission factors for the type of kiln from the Compilation of Air Pollutant Emission Factors (AP-42), Fifth Edition, January 1995*, Supplements A through G, December 2000* and the NO_x Control Technologies for the Cement Industry, Final Report, September 19, 2000*.

(2) For kilns, the site-specific emission factor developed from representative emissions testing, pursuant to 40 CFR 60, Appendix A, Method 7*, 7A*, 7C*, 7D*, or 7E*, based on a range of typical operating conditions. The owner or operator must:

(A) establish that these operating conditions are representative, subject to approval by the department; and

(B) certify that the emissions testing is being conducted under representative conditions.

(3) For kilns, an alternate method for establishing the emission factors, when submitted with supporting data to substantiate the emission factors and approved by the department and U.S. EPA as set forth in subsection (b).

(4) For affected boilers, as outlined in the site-specific compliance plan submitted under subsection (c).
