Technical Support Document 

EPA-R06-OAR-2012-0434

The Environmental Protection Agency (EPA) has the authority to establish the 

National Ambient Air Quality Standards (NAAQS) under the Clean Air Act (CAA) for each 

airborne pollutant. Once the NAAQS are set, individual states have the responsibility to 

achieve, maintain, and enforce the NAAQS in each of the Air Quality Control Regions within 

their state. Each state must prepare and submit a state implementation plan (SIP) outlining the 

path to satisfy the NAAQS for each identified pollutant. SIP requirements and procedures can 

differ depending on the nonattainment classification of the nonattainment area. Revisions are 

made to the SIP from time to time to guide the nonattainment area in reaching attainment of 

the NAAQS, and then maintaining the NAAQS. 

When EPA approves rules and rule revisions into the SIP, the rules become federally 

enforceable. 

The EPA approved the original Louisiana SIP on March 31, 1972 (37 FR 10869). Since then, 

revisions were periodically made to the Louisiana SIP. SIP revisions consist of rules adopted by 

the Louisiana Department of Environmental Quality (LDEQ) and subsequently adopted into the 

SIP. Revisions to general rules are usually submitted on an annual basis by the LDEQ. The 

revisions and adoption of the Air Quality rules and regulations are made in accordance with 

Louisiana R.S. 30:2019 and are published in the Louisiana Administrative Code (LAC). The 

latest revisions to Louisiana general rules was approved by EPA on July 5, 2011 (76 FR 

38977) which covered the years of 1996-2006. 

The intended outcome of this action is to update the Louisiana SIP to correspond to State 

regulations, conform to federally approved regulations, statutes, and EPA guidance. This 

Technical Support Document (TSD) is comprised of two Parts A and B.

Evaluation: In 2006, the Environmental Protection Agency revised the National Ambient Air 

Quality Standards (NAAQS) for particulate matter. The revised NAAQS address two categories 

of particle pollution: fine particles (PM2.5), which are 2.5 micrometers in diameter and smaller; 

and inhalable coarse particles (PM10), which are smaller than 10 micrometers. This Rule updates 

the Louisiana air quality regulations to include the revised federal particle standards. 

The EPA strengthened the 24-hour PM2.5 standard from the 1997 standard of 65 micrograms 

per cubic meter to 35 micrograms per cubic meter, and retained the current annual PM2.5 standard 

of 15 micrograms per cubic meter. For inhalable coarse particles, EPA retained the existing 

national 24-hour PM10 standard of 150 micrograms per cubic meter and revoked the annual 

PM10 standard. 

The basis and rationale for this Rule are to update the Louisiana air quality regulations to 

include the revised NAAQS for particulate matter to ensure continued protection of the 

environment and human health. The revision is consistent with the NAAQS for PM2.5 and PM10

standards of 40 CFR 50, also see 71 FR 61144 (Oct 17, 2006), and 

http://www.epa.gov/air/criteria.html (URL dated 26 March, 2015). We recommend its proposed 

approval into the SIP.

Practices; maintenance of control equipment; and recordkeeping requirements. The intent of 

this revision is to establish clear performance standards that apply equally to all businesses 

that engage in abrasive blasting activities. The basis and rational for this rule revision are to 

improve air quality by reducing particulate matter emissions. The AQ249 (30 LAC 33:III

§§1323, 1325, 1327, 1329, 1331, and 1333) combined with AQ303 (§§1327, 1329) will provide 

for PM emission control from abrasive blasting activities, facilitate compliance determination, 

and enhance the SIP. We recommend their proposed approval into the SIP.

Chapter 15. Emission Standards for Sulfur Dioxide

§1502. Applicability

A. The provisions of this Chapter are applicable to the following sources: 

1. new or existing sulfuric acid production units; 

2. new or existing sulfur recovery plants; and 

3. all other single point sources that emit or have the potential to emit 5 

tons per year or more of sulfur dioxide into the atmosphere. 

AUTHORITY NOTE: Promulgated in accordance with R.S. 30:2054. HISTORICAL NOTE: 

Promulgated by the Department of Environmental Quality, Office of the Secretary, Legal Affairs 

Division, LR 33:** (June 2007). 

§1503. Emission Limitations and Compliance

As used in this Section a three-hour average means the average emissions for any 

three consecutive one-hour periods (each commencing on the hour), provided that the number 

of three- hour periods during which the SO2 limitation is exceeded is not greater than the 

number of one- hour periods during which the SO2 limitation is exceeded. 

A. Sulfuric Acid Plants—New and Existing. The emissions of sulfur dioxide and 

acid mist from new sulfuric acid production units that commence construction or 

modification after August 17, 1971, shall be limited to that specified in 40 CFR 60.82 and 

60.83, as incorporated by reference in LAC 33:III.Chapter 30, i.e., 4.0 pounds of 

SO2/ton of 100 percent H2SO4 (2 kilograms/metric ton) and 0.15 pounds of sulfuric 

acid mist/ton of 100 percent H2SO4 (.075 kilograms/metric ton), respectively (three-hour 

averages). Emissions from existing units shall be limited as follows: 

1. SO2—not more than 2000 ppm by volume (three-hour average); 

2. sulfuric acid mist—not more than 0.5 pounds/ton of 100 percent 

H2SO4 (0.25 kilograms/metric ton) (three-hour average). 

B. ... 

C. All Other Sources—New and Existing Not Elsewhere Discussed. No person 

shall discharge gases from the subject sources which that contain concentrations of SO2 

which exceed in excess of 2,000 parts per million (ppm) by volume at standard conditions 

(three-hour average), or any applicable Federal NSPS or NESHAP emission limitation, 

whichever is more stringent. Units emitting Single point sources that emit or have the 

potential to emit less than 250 tons per year of sulfur compounds measured as sulfur 

dioxide may be exempted from the 2,000 ppm(v) limitation by the administrative authority. 

D. Measurement of Concentrations Compliance 

1. Analytical Methods. The methods listed in Table 4 or any such 

equivalent method as may be approved by the administrative authority* shall be utilized 

used to determine sulfur dioxide and sulfuric acid mist concentrations in stack gases 

compliance with the appropriate emission limitations set forth in Subsections A-C of this 

Section. These methods are 

to shall be used for the following: 
20 

a. initial compliance determinations; and 

b. for any additional compliance determinations as requested 

by the administrative authority. for those facilities not subject to continuous emission 

monitoring. 

2. Calibration of Equipment Required. Measurement equipment shall 

be periodically calibrated to comply with minimal American Bureau of Standards Ccriteria. 

3. The data collected from a sulfur dioxide continuous emission 

monitoring system (CEMS) may be used to determine initial compliance with the sulfur 

dioxide emission limitations of this Section. 

4. As used in this Section a three-hour average means the average 

emissions for any three consecutive one-hour periods (each commencing on the hour), 

provided that the number of three-hour periods during which the SO2 limitation is exceeded 

is not greater than the number of one-hour periods during which the SO2 limitation is 

exceeded.

Evaluation: The revisions to Chapter 15: Sections 1502, 1503, 1507, 1511, and 1513 are 

substantive. Section 1509 was not amended in this particular revision. 

Previously, in order to expedite rulemaking on other chapters of Louisiana SIP, through a request 

letter dated January 25, 2011, LDEQ withdrew various general revisions to Chapter 15 (OS65, 

adopted by State on 10/20/05; AQ180 adopted by State on 12/20/98; and AQ248 adopted by 

State on 05/20/05) from EPA’s review. On October 2, 2015 LDEQ withdrew its revisions 

(AQ271) to Chapter 15 from our review. Chapter 15 is subject to EPA’s National SSM SIP Call 
27 

of June 12, 2015 (80 FR 33840). Revisions and evaluation of Chapter 15 are expected to be 

handled within the context of National SSM SIP Call. See 

The AQ271 in Section 1507 Exceptions incorporates affirmative defense provisions for excess 

emission resulting from startup. Furthermore, Chapter 15 in Section 1503 Exceptions will 

provide for administrative authority to exempt startup-related excess emissions, if the owner or 

operator submits a written report certifying 5 affirmative defense criteria within 7 days of an 

occurrence. See 1507(A)(1)(b)(i) though (v). 

The AQ271 in Section 1507 Exceptions incorporates affirmative defense provisions for excess 

emission resulting from “on-line operating adjustments” (upsets). 

Similarly, Chapter 15 in Section 1507 will provide for administrative authority to exempt “online operating adjustments”-related excess emissions, if the owner or operator submits a written 

report certifying 5 affirmative defense criteria within 7 days of an occurrence. See 

1507(B)(1)(b)(i) though (v). 

Section 1507 Exceptions cross references Section 1503 Emission Limitations and Compliance. 

For these reasons we recommended LDEQ to withdraw AQ271 from EPA’s review at this time, 

and allow the issues associated with Chapter 15 to be addressed within the context of the 

National SSM SIP Call.

AQ 272 

AQ272 concerns revisions to Chapter 21: Section 2103. 

Chapter 21. Control of Emission of Organic Compounds

Subchapter A. General

§2103. Storage of Volatile Organic Compounds

A.-G3....

4. JP-4 fuels stored in horizontal underground tanks;

5. with regard to the requirements of Paragraph C.l of this Section, any storage tank that is 

used for less than two weeks in the calendar year, provided that the tank is empty and liquidfree when not in use; and

6. with regard to the submerged fill pipe provisions of Subsection A of this Section, tanks, 

drums, or other containers storing pyrophoric catalyst at the Vistalon Production Facility of 

ExxonMobil Chemical Company's Baton Rouge Chemical Plant.

H. -J. ... 

Evaluation: In its Louisiana Register issue of March 20, 2007 State wrote: “This Rule exempts 

drums storing pyrophoric catalyst at the Vistalon Production Facility of ExxonMobil 

Chemical Company Baton Rouge Chemical Plant from the submerged fill pipe provisions of 

LAC 33:1II.2103.A. Existing drums are currently operating under Permit No. 2376-VO, 

issued April 4, 2006, and are identified as follows: EQT583, T-3304A - Catalyst Drum 

(VCD-107A), 9400 gallons; EQT584, T-3304B - Catalyst Drum (VCD-l07B), 9400 

gallons; EQT585, T-3304C - Catalyst Drum (VCD-107C), 4700 gallons; EQT586, T-3304D 

- Catalyst Drum (VCD-107D), 4700 gallons. The drums in question are used to store an alkyl 

catalyst that is very pyrophoric in nature; the material can spontaneously ignite if 

exposed to even trace levels of oxygen and moisture. It has been decided that these tanks do 

not qualify as pressure vessels because of the frequency at which they vent to the atmosphere 

(every 1 to 1.5 days). As such, they would normally be subject to the submerged fill pipe 

provisions of LAC 33:111.2103.A, which seeks to prevent vapor or gas loss to the atmosphere 
30 

during filling operations. Any overpressure in a closed storage system fed through a 

submerged fill pipe could lead to materials backing up into and possibly overfilling 

delivery equipment or other upstream facilities, causing a dangerous condition in the case of 

this kind of catalyst. Therefore, the manufacturer of the catalyst has recommended that the 

material be transferred using a free-fall method. No increase in actual emissions above current 

levels will be authorized by this Rule. The basis and rationale for this Rule are to provide 

drums storing pyrophoric catalyst with an exemption from regulations with which strict 

conformity would create an unreasonable risk to public health, welfare, and safety.” For health, 

and safety reasons, to avoid potential fire hazard, and the fact that there will be no increase in 

actual emissions we recommend proposed approval of this revision into SIP. 

MM002 

MM002, among other things, concerns rule revisions to Sections 501, 504, 505, 506, and 507 

that belong to the Air Permit Section, and will not be addressed by the Air Planning Section
