Technical Support Document (TSD) for an Exemption

Source Description and Location

Source Name: Combined Support Maintenance Shop #2 Source Location: Building 630 Camp Atterbury, Edinburgh, IN 46124 County: Johnson SIC Code: 7538 (General Automotive Repair Shops)

7699 (Repair Shops and Related Services, Not Elsewhere Classified) 9711(National Security)

Exemption No.: E081-34559-00074 Permit Reviewer: Nida Habeeb On May 21, 2014, the Office of Air Quality (OAQ) received an application from Combined Support Maintenance Shop #2 related to the construction and operation of a new general automotive repair shop.

Source Definition The Indiana Army and Air National Guard (National Guard) operates Camp Atterbury. Camp Atterbury is composed of many air emission units. The National Guard believes that the Combined Support Maintenance Shop #2 (CSMS) is a separate source from Camp Atterbury and has requested that it be removed from the Camp Atterbury permit. IDEM, OAQ has examined whether the CSMS should be considered separate “source” as defined at 326 IAC 1-2-73. In order for Camp Atterbury and the CSMS, both referred to as “plants”, to continue to be combined as one source, they must meet all three of the following criteria:

(1) the plants must be under common ownership or common control; (2) the plants must have the same two-digit Standard Industrial Classification (SIC) Code or one

must serve as a support facility for the other; and, (3) the plants must be located on contiguous or adjacent properties.

Camp Atterbury is under the control of the Camp Commander. The CSMS is under the control of the Indiana Guard’s Director of Logistics. Both the Camp Commander and the Director of Logistics report to the Indiana Guard’s Adjutant General. The plants are both owned and controlled by the Indiana Guard. They meet the first element of the source definition. The SIC Code Manual of 1987 sets out how to determine the proper SIC Code for each type of business. More information about SIC Codes is available at http://www.osha.gov/pls/imis/sic_manual.html on the Internet. IDEM, OAQ is aware of the U.S. EPA’s August 2, 1996 memorandum, Major Source Determinations for Military Installations under the Air Toxics, New Source Review, and Title V Operating Permit Programs of the Clean Air Act (the DOD memo). The DOD memo is available at http://www.epa.gov/region07/air/title5/t5memos/dodguid.pdf on the Internet. The DOD memo is not binding on IDEM but it does provide guidance, as the term “major source” in the Title V program is almost identical to the term “source” in 326 IAC 1-2-73. The DOD memo states that, historically, all activities at a military installation have been grouped under the two-digit SIC Code 97, for the major group National Security and International Affairs. The DOD memo states that using the two-digit Sic Code 97 for all activities at a military installation may inappropriately aggregate activities that would not be grouped together at nonmilitary facilities. The memo suggests that plants at military installations may be assigned appropriate two-digit SIC Codes as if they were not located at military installations (see DOD memo,

http://www.osha.gov/pls/imis/sic_manual.html

http://www.epa.gov/region07/air/title5/t5memos/dodguid.pdf

Combined Support Maintenance Shop #2 Page 2 of 12 Edinburgh, Indiana TSD for Exemption No. E081-34559-00074 Permit Reviewer: Nida Habeeb pages 3 to 4). Using the DOD memo approach, Camp Atterbury, as a military installation, would still have the two-digit SIC Code 97, for the major group National Security and International Affairs. The CSMS, however, which does maintenance on vehicles, would have the two-digit SIC Code 75, for the major group Automotive Repair, Services and Parking. Therefore, the plants do not have the same two-digit SIC Code. A plant is a support facility to another plant if it dedicates 50% or more of its output to another plant. The CSMS does the highest level of vehicle maintenance, supporting maintenance shops for several Indiana Guard locations around the state. It supplies less than 35% of its total output to Camp Atterbury. Since the CSMS and Camp Atterbury do not have a support relationship and have different two-digit SIC Codes, they do not meet the second part of the source definition. The CSMS is located on the same property as the rest of Camp Atterbury; therefore, the third element of the source definition is met. Since Camp Atterbury and the CSMS do not meet all three parts of the source definition, IDEM, OAQ has determined that they are not part of the same source.

Existing Approvals There have been no previous approvals issued to this source.

County Attainment Status

The source is located in Johnson County:

Pollutant Designation SO2 Better than national standards. CO Unclassifiable or attainment effective November 15, 1990. O3 Unclassifiable or attainment effective July 20, 2012, for the 2008 8-hour ozone standard.1

PM2.5 Attainment effective July 11, 2013, for the annual PM2.5 standard. PM2.5 Unclassifiable or attainment effective December 13, 2009, for the 24-hour PM2.5 standard. PM10 Unclassifiable effective November 15, 1990. NO2 Cannot be classified or better than national standards. Pb Unclassifiable or attainment effective December 31, 2011.

1Unclassifiable or attainment effective October 18, 2000, for the 1-hour ozone standard, which was revoked effective June 15, 2005.

(a) Ozone Standards

Volatile organic compounds (VOC) and Nitrogen Oxides (NOx) are regulated under the Clean Air Act (CAA) for the purposes of attaining and maintaining the National Ambient Air Quality Standards (NAAQS) for ozone. Therefore, VOC and NOx emissions are considered when evaluating the rule applicability relating to ozone. Johnson County has been designated as attainment or unclassifiable for ozone. Therefore, VOC and NOx emissions were reviewed pursuant to the requirements for Prevention of Significant Deterioration (PSD), 326 IAC 2-2.

(b) PM2.5

Johnson County has been classified as attainment for PM2.5. On May 8, 2008, U.S. EPA promulgated the requirements for Prevention of Significant Deterioration (PSD) for PM2.5 emissions. These rules became effective on July 15, 2008. On May 4, 2011, the air pollution control board issued an emergency rule establishing the direct PM2.5 significant level at ten (10) tons per year. This rule became effective June 28, 2011. Therefore,

Combined Support Maintenance Shop #2 Page 3 of 12 Edinburgh, Indiana TSD for Exemption No. E081-34559-00074 Permit Reviewer: Nida Habeeb

direct PM2.5, SO2, and NOx emissions were reviewed pursuant to the requirements for Prevention of Significant Deterioration (PSD), 326 IAC 2-2.

(c) Other Criteria Pollutants

Johnson County has been classified as attainment or unclassifiable in Indiana for all other criteria regulated pollutants. Therefore, these emissions were reviewed pursuant to the requirements for Prevention of Significant Deterioration (PSD), 326 IAC 2-2.

Fugitive Emissions

The fugitive emissions of criteria pollutants, hazardous air pollutants, and greenhouse gases are counted toward the determination of 326 IAC 2-1.1-3 (Exemptions) applicability.

“Integral Part of the Process” Determination In October 1993 a Final Order Granting Summary Judgment was signed by Administrative Law Judge (“ALJ”) Garrettson resolving an appeal filed by Kimball Hospitality Furniture Inc. (Cause Nos. 92-A-J-730 and 92-A-J-833) related to the method by which IDEM calculated potential emissions from woodworking operations. In his findings, the ALJ determined that particulate controls are necessary for the facility to produce its normal product and are integral to the normal operation of the facility, and therefore, potential emissions should be calculated after controls. Based on this ruling, potential emissions from WW1 and WW2 for particulate matter were calculated after consideration of the controls.

Enforcement Issues There are no pending enforcement actions related to this source.

Emission Calculations See Appendix A of this TSD for detailed emission calculations.

Permit Level Determination – Exemption The following table reflects the unlimited potential to emit (PTE) of the entire source before controls. Control equipment is not considered federally enforceable until it has been required in a federally enforceable permit.

exemption, because the unlimited potential to emit of the source is less than the Title V major source thresholds and the source is not required to obtain a Part 70 or Part 71 permit.

State Rule Applicability Determination

The following state rules are applicable to the source: (a) 326 IAC 2-1.1-3 (Exemptions)

Exemption applicability is discussed under the Permit Level Determination – Exemption section above.

(b) 326 IAC 2-4.1 (Major Sources of Hazardous Air Pollutants (HAP))

The potential to emit of any single HAP is less than ten (10) tons per year and the potential to emit of a combination of HAPs is less than twenty-five (25) tons per year. Therefore, this source is an area source under Section 112 of the Clean Air Act (CAA) and not subject to the provisions of 326 IAC 2-4.1.

(c) 326 IAC 2-6 (Emission Reporting)

Pursuant to 326 IAC 2-6-1, this source is not subject to this rule, because it is not required to have an operating permit under 326 IAC 2-7 (Part 70), it is not located in Lake, Porter, or LaPorte County, and it does not emit lead into the ambient air at levels equal to or greater than 5 tons per year. Therefore, 326 IAC 2-6 does not apply.

(d) 326 IAC 5-1 (Opacity Limitations)

Pursuant to 326 IAC 5-1-2 (Opacity Limitations), except as provided in 326 IAC 5-1-3 (Temporary Alternative Opacity Limitations), opacity shall meet the following, unless otherwise stated in this exemption:

(1) Opacity shall not exceed an average of forty percent (40%) in any one (1) six (6) minute

averaging period as determined in 326 IAC 5-1-4.

(2) Opacity shall not exceed sixty percent (60%) for more than a cumulative total of fifteen (15) minutes (sixty (60) readings as measured according to 40 CFR 60, Appendix A, Method 9 or fifteen (15) one (1) minute nonoverlapping integrated averages for a continuous opacity monitor) in a six (6) hour period.

(e) 326 IAC 6-4 (Fugitive Dust Emissions Limitations)

Pursuant to 326 IAC 6-4 (Fugitive Dust Emissions Limitations), the source shall not allow fugitive dust to escape beyond the property line or boundaries of the property, right-of-way, or easement on which the source is located, in a manner that would violate 326 IAC 6-4.

(f) 326 IAC 6-5 (Fugitive Particulate Matter Emission Limitations)

The source is not subject to the requirements of 326 IAC 6-5, because the source does not have potential fugitive particulate emissions greater than 25 tons per year. Therefore, 326 IAC 6-5 does not apply.

(g) 326 IAC 8-1-6 (VOC Rules: General Reduction Requirements for New Facilities)

Each of the emission units at this source is not subject to the requirements of 326 IAC 8-1-6, since the unlimited VOC potential emissions from each emission unit is less than twenty-five (25) tons per year.

Methodology:

**Emission Factor for plasma cutting from American Welding Society (AWS). Trials reported for wet cutting of 8 mm thick mild steel with 3.5 m/min cutting speed (at 0.2 g/min emitted). Therefore, the emission factor for plasma cutting is for 8 mm thick rather than 1 inch, and the maximum metal thickness is not used in calculting the emissions. Using AWS average values: (0.25 g/min)/(3.6 m/min) x (0.0022 lb/g)/(39.37 in./m) x (1,000 in.) = 0.0039 lb/1,000 in. cut, 8 mm thick

Emissions, lbs/day = emissions, lbs/hr x 24 hrs/dayEmissions, tons/yr = emissions, lb/hr x 8,760 hrs/year x 1 ton/2,000 lbs.

NotesControl Efficiency = 95%In October of 1993 a Final Order Granting Summary Judgment was signed by an Administrative Law Judge("ALJ") resolving an appeal of an IDEM permit related to the method by which IDEM calculated potentialemissions from woodworking operations. In his findings, the ALJ determined that particulate controls werenecessary for the facility, and therefore, potential emissions were to be calculated after controls. Based onthis ruling, potential emissions for particulate matter were calculated after consideration of the controls.
