326 Ind. Admin. Code 2-6-4

Current through December 12, 2024

Section 326 IAC 2-6-4 - Requirements

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

Affected: IC 13-15; IC 13-17

Sec. 4.

(a) A source subject to section 1(a) of this rule shall report estimated actual emissions in the emission statement of the following pollutants:

(1) Carbon monoxide (CO).

(2) Volatile organic compounds (VOC).

(3) Oxides of nitrogen (NO_x).

(4) Particulate matter less than or equal to ten (10) micrometers (PM₁₀).

(5) Sulfur dioxide (SO₂).

(6) Lead and lead compounds, including any unique chemical substance that contains lead.

(7) Particulate matter less than or equal to two and five-tenths (2.5) micrometers (PM_2.5).

(8) Ammonia (NH₃).

(b) Emissions from processes that are insignificant or trivial activities as defined in 326 IAC 2-7-1 are not required to be reported in an emission statement.

(c) The emission statement submitted by the source must contain, at a minimum, the following information:

(1) Certification by a responsible official that the information in the emission statement is accurate based on reasonable estimates using data available to the preparers and on a reasonable inquiry into records and persons responsible for the operation of the source, and is true, accurate, and complete. The certification shall include the:

(A) full name;

(B) title;

(C) signature;

(D) date of signature; and

(E) telephone number; of the person signing the certification.

(2) Source identification information, to include the following:

(A) Full name, physical location, and mailing address of the source.

(B) Source universal transverse mercator (UTM) or latitude and longitude.

(C) North American Industry Classification System (NAICS) code.

(3) Operating data, for each emission unit or emissions group, to include the following:

(A) Percent annual throughput by quarter as defined in section 2 of this rule.

(B) Days per week in operation.

(C) Design capacity.

(D) Hours per day in operation.

(E) Hours per year in operation.

(F) Maximum nameplate capacity.

(4) For reporting purposes, multiple stacks that vent to the atmosphere may be grouped together to reflect any grouping of process units. Stack parameters include the following:

(A) Stack identification.

(B) Stack height and diameter (in feet).

(C) Universal transverse mercator (UTM) or latitude and longitude coordinates.

(D) Exit gas temperature (degrees Fahrenheit).

(E) Exit gas flow rates in cubic feet per minute.

(5) Emissions information for each process, to include the following:

(A) The estimated actual emissions of all pollutants listed in subsection (a) at the process level in tons per year. Actual emission estimates must:

(i) include upsets, downtime, and fugitive emissions; and

(ii) follow an emission estimation method. Fugitive emissions may be reported as plantwide or grouped together in a logical manner. If control efficiencies are adjusted because of upsets, downtime, and malfunctions, information must be provided about how the control efficiencies are calculated.

(B) Emissions of VOC, PM₁₀, and PM_2.5 shall be reported as total VOC, PM₁₀, and PM_2.5 emissions, respectively.

(C) Calendar year for the emissions.

(D) Estimated emissions method code provided by the department.

(E) Emission factor, if part of emissions calculation. Acceptable sources of an emission factor include the following:

(i) AP-42, "Compilation of Air Pollutant Emission Factors AP-42" as defined at 326 IAC 1-2-20.5.

(ii) Site-specific values accepted by the department and the U.S. EPA.

(iii) Other documentable methodology accepted by the department and the U.S. EPA.

(F) Source classification code (SCC).

(G) Annual process rate (annual throughput) to the extent it is part of emissions calculation.

(H) If part of emissions calculation, the following:

(i) Ash content.

(ii) Sulfur content.

(iii) Heat content.

(6) Control equipment information, to include the following:

(A) Capture efficiency.

(B) Current control equipment efficiency percentage unless a controlled emission factor is applied. The actual efficiency should reflect the total control efficiency from all control equipment for each process pollutant. If the actual control efficiency is unavailable, the:

(i) efficiency designed by the manufacturer may be used; or

(ii) control efficiency limit imposed by a permit should be used.

(C) Control equipment identification code.

(d) Nothing in this rule requires stack testing.
