Re: State Implementation Plan Submittal for 

Indiana Regarding 326 lAC 7-4-14; Operations at 

ArcelorMittal Burns Harbor LLC, LSA# 07-88 

Pursuant to Section 11 0 of the 1990 Clean Air Act Amendments and Title 13 of the 

Indiana Code, the Indiana Department of Environmental Management (IDEM) submits an 

amendment to the Indiana state implementation plan (SIP). This rule revision amends 

Indiana's sulfur dioxide emission limitation rule for Porter County at 326 lAC 7-4-14. This 

rule was adopted in a rulemaking that also amended 326 lAC 6-6-5 concerning 

ArcelorMittal's fugitive particulate matter emission· control plan. At this time, IDEM is not 

requesting SIP approval of the amendments to 326 lAC 6-6-5. 

Sulfur dioxide (S02) emission limits for sources at ArcelorMittal are listed at 326 

lAC 7-4-14. The rule established an S02 limit for the facility's blast furnace gas flare. The 

so2 emission limits established in this rule for processes using the blast furnace gas account 

for all of the available blast furnace gas; therefore, the emission limit for the blast furnace 

gas flare is redundant and unnecessary to assure continued protection of the National 

Ambient Air Quality Standard (NAAQS) for S02 in Porter County. Removing the S02 blast 

furnace gas flare limit from 326 lAC 7-4-14 will not result in or allow an increase in actual 

so2 emissions. 

The rule was final adopted on July 1, 2009, by the Air Pollution Control Board. No 

comments were received at the hearing. The rule was filed with the Publisher of the Indiana 

Register on September 29,2009, and became effective on October 29,2009. No modeling 

was necessary for this submittal. 

Recycled Paper (i) An Equal Opportunity Employer Please Recycle () 
Throughout the development of these amendments to the existing rule, 326 lAC 7-4-

14, IDEM staff worked closely with your staff to ensure that any potential problems that 

might exist with this requested state implementation plan revision would be resolved. I 

request that U.S. EPA approve these modifications oflndiana's state implementation plan. If 

you have any questions regarding this submittal, please contact Scott Deloney, Air Programs 

Branch Chief, Office of Air Quality at 317-233-5694.

TITLE 326 AIR POLLUTION CONTROL BOARD 

SECOND NOTICE OF COMMENT PERIOD 

LSA Document #07 -88 

DEVELOPMENT OF AMENDMENTS TO RULES CONCERNING OPERATIONS AT ISG BURNS HARBOR LLC 

PURPOSE OF NOTICE 

The Indiana Department of Environmental Management (IDEM} has developed draft rule language for 

amendments to 326 lAC 6-6-5, concerning ISG Burns Harbor LLC's fugitive particulate matter emission control 

plan, and to 326 lAC 7-4-14, concerning sulfur dioxide (S02

} emission limits for ISG Burns Harbor LLC's blast 

furnace flare. IDEM seeks comment on the affected citations listed and any other provisions of Title 326 that may 

be affected by this rulemaking. 

HISTORY 

First Notice of Comment Period: February 21, 2007, Indiana Register (DIN: 20070221-IR-326070088FNA}. 

CITATIONS AFFECTED: 326 lAC 6-6-5; 3261AC 7-4-14. 

AUTHORITY: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11. 

SUBJECT MATTER AND BASIC PURPOSE OF RULEMAKING 

Basic Purpose and Background 

The ISG Burns Harbor LLC plant operates two blast furnaces and is capable of producing over 5 million tons 

of raw steel annually. Hot-rolled, cold-rolled, and coated-sheet products are made at the site. Operations include 

a 160" plate mill and a 11 0" plate mill capable of producing over one million tons of plate each year. ISG Burns 

Harbor LLC was formerly known as the Bethlehem Steel plant and is located on Lake Michigan in Northwestern 

Indiana. 

In two separate letters dated May 25, 2006, ISG Burns Harbor LLC formally requested that IDEM propose to 

the Air Pollution Control Board amendments to 326 lAC 6-6-5 and 326 lAC 7-4-14. This rulemaking proposes 

amendments to two separate rules concerning fugitive particulate matter and sulfur dioxide emissions at ISG 

Burns Harbor LLC. 

326 lAC 6-6-5 ISG Burns Harbor fugitive particulate matter control plan 

The fugitive dust control strategy outlined in 326 lAC 6-6-5 has been effective since 1984 and addresses 

fugitive particulate matter emissions from roads and coal storage piles at the ISG Burns Harbor LLC steelmaking 

plant. The rule imposes requirements for controlling fugitive particulate matter emissions by prescribing the 

specific roads that are to be treated, the specific amount of dust suppressant, and the frequencies those roads 

are to be treated. 326 lAC 6-6-5 also specifies the use of a tractor mounted broom for controlling fugitive 

particulate matter. 

On May 4, 2006, ISG Burns Harbor LLC requested a variance from the requirements of 326 lAC 6-6-5 on the 

grounds that the rule does not permit the company the operational flexibility to reconfigure roads at the plant or to 

use alternative dust suppressant equipment or application frequencies, as those details are specified in the rule. 

ISG Burns Harbor LLC maintains that the specific control strategies required by 326 lAC 6-6-5 do not permit 

alternative control strategies that may be more efficient, effective, and less costly. 

On November 17, 2006, IDEM granted a variance from the requirements of 326 lAC 6-6-5 to ISG Burns 

Harbor LLC on the condition that the company implement an approved alternative fugitive particulate matter 

emissions control plan in place of the requirements outlined in 326 lAC 6-6-5. The variance is effective through 

December 5, 2007. The approved fugitive particulate matter emissions control plan is modeled after control plan 

requirements from 326 lAC 6-5-3 through 326 lAC 6-5-9. 326 lAC 6-5-3 through 326 lAC 6-5-9 outline the control 

requirements for particulate matter emissions, the contents of an appropriate fugitive particulate matter control 

plan, and the process for plan approval by IDEM. 

326 lAC 7-4-14 Porter County sulfur dioxide emission limitations 

Blast furnace gas is a byproduct of the steelmaking process generated at the blast furnace. ISG Burns 

Harbor LLC cleans the blast furnace gas generated at their facility and uses it as a fuel in the blast furnace 

stoves, coke ovens, and the power station boilers. The blast furnace gas flare is a control device used to prevent 

excess pressure from forming in the blast furnace gas supply line. The blast furnace gas flare is used when 

excess gas is produced beyond the capacity of the blast furnace and combustion sources to consume it. 326 lAC 

7-4-14 establishes a 0.071bs/MMBtu S02 emission limit for ISG Burns Harbor LLC's blast furnace flare. 

On May 4, 2006, ISG Burns Harbor LLC requested a variance from the 326 lAC 7-4-14 S02 emission limit for 

their blast furnace gas flare. 326 lAC 7-4-14 SO emission limits for the steelmaking plant attribute 100% of the 

available blast furnace gas as being used in the blast furnace stove, coke ovens, and the power station boilers. 

Date: Dec 02,2009 1:14:47PM EST DIN: 20070808-IR-326070088SNA Page 1 
Indiana Register 

ISG Burns Harbor LLC claimed that compliance with the S02 emission limits established for the processes using 

the blast furnace gas assures protection of the National Amo1ent Air Quality Standard for S02

, regardless of the • 

presence of, or with, an SO emission limit for the blast furnace gas flare. In addition, ISG Burns Harbor LLC 

states that the sulfur contenl present in raw materials processed at the blast furnaces is highly variable. Because 

the nature of the steelmaking process requires a continuous addition of raw materials to the blast furnace, it is 

technically infeasible to manage the sulfur content of materials charged in the blast furnace to achieve compliance 

with the blast furnace flare S02 emission limit. Finally, ISG Burns Harbor LLC notes in the May 4, 2006, variance 

request that the blast furnace gas flare is necessary for the safe operation of the blast furnace gas distribution 

system, S02 emission limits are not imposed on flares for any other steelmaking operations or for any other flares 

in Indiana, and add-on control technologies do not currently exist for S02 emission control at blast furnace gas 

flares. 

On November 17, 2006, IDEM granted a variance from the blast furnace gas flare SO emission limit 

established in 326 lAC 7-4-14 to ISG Burns Harbor LLC. This variance is effective throughUecember 5, 2007. 

IC 13-14-9-41dentification of Restrictions and Requirements Not Imposed under Federal Law 

The draft rule imposes restrictions and requirements on persons to whom the draft rule applies that are "not 

imposed under federal law". This rulemaking amends the current state rule 326 lAC 6-6-5 and replaces the 

fugitive particulate matter emission control requirements with requirements for the submission of a fugitive 

particulate matter emission control plan for IDEM approval. 

(1) 326 lAC 6-6-5 serves an important function by outlining required practices in order to minimize the 

amount of fugitive particulate matter introduced to the surrounding areas by the ISG Burns Harbor LLC 

steelmaking plant. All sections under 326 lAC 6-6 were disapproved as a proposed revision to Indiana's State 

Implementation Plan (SIP) effective March 9, 1987. As a result, 326 lAC 6-6-5 remains a state-only rule. 

U.S. EPA found in a final rulemaking action dated February 5, 1987 (52 FR 3640) that 326 lAC 6-6 was "not 

approvable under the Clean Air Act (Act) due to deficiencies in the regulation itself and in the modeling analysis 

and emission inventory submitted to support the regulation". The fugitive dust control plan outlined in 326 lAC 6-6-

.Q was not mentioned in the U.S. EPA's discussion on deficiencies in 326 lAC 6-6. This rulemaking proposes to 

substitute the proscribed fugitive particulate matter control requirements of 6-6-5 with a rule requiring ISG Burns 

Harbor LLC to submit and implement a fugitive particulate matter emission control plan for IDEM review and 

approval. 

(2) ISG Burns Harbor LLC expects the ability to modify its fugitive particulate matter emission control strategy 

will result in the same or better level of fugitive particulate matter emission control more efficiently by allowing • 

the flexibility to amend the control plan strategy as required to address changes in road configurations or 

operations. Additionally, ISG Burns Harbor LLC requests the flexibility to develop a fugitive particulate matter 

control plan subject to IDEM's approval instead of having the plan prescribed by the rule. ISG Burns Harbor 

LLC believes that future revisions of the control plan will be more difficult and costly to achieve if the details of 

the control plan continue to be prescribed by rule. 

(3) IDEM relied in part on arguments for an alternative fugitive particulate matter control plan for ISG Burns 

Harbor LLC in the development of the proposed amendments to 326 lAC 6-6-5. These arguments were 

contained in letters from ISG Burns Harbor LLC to IDEM dated May 4, 2006, May 25, 2006, and March 23, 

2007. These letters are available for public inspection and copying at the Indiana Department of 

Environmental Management, Office of Air Quality, Indiana Government Center-North, Tenth Floor, 100 North 

Senate Avenue, Indianapolis, Indiana 46205. 

Potential Fiscal Impact 

There is no fiscal burden on ISG Burns Harbor LLC as a result of this rulemaking. The rule should reduce 

costs for ISG Burns Harbor LLC as the ability to design a modern fugitive particulate matter emission control plan 

may reduce costs associated with maintaining outdated control equipment currently required under 326 lAC 6-6-

.Q. 

Public Participation and Workgroup Information 

No workgroup is planned for the rulemaking. If you feel that a workgroup or other informal discussion on the 

rule is appropriate, please contact Sean Gorman, Rules Development Section, Office of Air Quality at (317) 

234-3533 or (800) 451-6021 (in Indiana). 

SUMMARY/RESPONSE TO COMMENTS FROM THE FIRST COMMENT PERIOD 

IDEM requested public comment from February 21,2007, through March 23, 2007, on alternative ways to 

achieve the purpose of the rule and suggestions for the development of draft rule language. IDEM received 

comments from the following party by the comment period deadline: 

ISG Burns Harbor LLC 

Following is a summary of the comments received and IDEM's responses thereto: 

Comment: The specific dust control measures required by 326 lAC 6-6-5 are no longer the most efficient or • 

effective methods for controlling fugitive emissions from the roadways at the Burns Harbor facility. ISG Burns 

Harbor LLC is the only steel mill facility in Indiana that has prescriptive fugitive dust control measures codified in a

Indiana Register 

rule; ISG Burns Harbor LLC is seeking a change in the rule to be allowed to establish a control plan for IDEM 

review and approval, as other Indiana steel mills and manufacturing operations do . 

Comment: We request that 326 lAC 6-6-5 be amended to allow ISG Burns Harbor LLC to operate under the 

alternative fugitive particulate matter control plan approved by IDEM under the November 17, 2006 variance. We 

further request that ISG Burns Harbor LLC be permitted to update the control plan consistent with 326 lAC 6-5-8 

"Revision of Control Plans". 

Comment: We suggest that 326 lAC 6-6-5 be amended to require ISG Burns Harbor LLC'S fugitive 

particulate matter emission control plan meet the content requirements of 326 lAC 6-5-5 and the approval 

requirements of 326 lAC 6-5-7. 

Response: IDEM agrees that there may be more efficient and less costly methods for achieving at least the 

same level of fugitive particulate matter emission control as currently exists under 326 lAC 6-6-5. An amendment 

to 326 lAC 6-6-5 requiring the submission of an alternative fugitive particulate matter control plan for IDEM review 

and approval will permit ISG Burns Harbor LLC the flexibility to adjust its control strategy as conditions or 

technologies dictate, while at the same time allowing IDEM to ensure that an appropriate level of fugitive 

particulate matter control is maintained. 

Comment: The sulfur dioxide emission limit at 326 lAC 7-4-14 for ISG Burns Harbor LLC'S blast furnace flare 

represents the only S02 emission limit for a blast furnace flare in Indiana. All blast furnace gas flare S02 emission 

limits for sources in neighboring Lake County were recently removed based on IDEM's rationale that counting 

emissions from the flare effectively double counted emissions that were already being considered at the locations 

where blast furnace gas is burned at boilers, stoves, and the furnaces. 

Comment: Removing the blast furnace gas flare S02 emission limit from 326 lAC 7-4-14 will not affect the 

existing air quality modeling used to support the other emission limits in 326 lAC 7-4-14. The amount of blast 

furnace gas included in the S02 modeling for the combustion units at ISG Burns Harbor LLC greatly exceeds the 

total amount of blast furnace gas available, even without flares. 

Comment: Eliminating the S02 emission limit at the flare will not cause any increase in actual S02. emissions, 

as ISG Burns Harbor LLC must continue to meet the S02 emission limits contained in 326 lAC 7-4-14 tor each of 

the combustion units. ISG Burns Harbor LLC uses as much blast furnace gas as possible to fuel boilers, stoves, 

and furnaces at the facility. The blast furnace gas flare is only used to control pressure in the blast furnace gas 

distribution system. 

Comment: The emission factor used to generate the blast furnace gas flare S02 emission limit of 0.07 

lb/MMBtu has not been peer reviewed or incorporated into U.S. EPA's Compilation of Emission Factors. Flares 

are inherently difficult to test and as a result, the emission factor is difficult to evaluate . 

. : Response: IDEM agrees that S02 emission limits are not imposed on flares for any other steelmaking 

operations or for any other flares in lnaiana. IDEM finds that there will be no negative environmental impact on the 

ambient air quality with respect to S02 emissions at ISG Burns Harbor LLC if the S02 emission limit for the blast 

furnace gas flare is removed from 32b lAC 7-4-14. Air quality modeling performed to establish the 326 lAC 7-4-14 

S02 emission limits for emission points at the steelmaking plant attribute 100% of the available blast furnace gas 

as oeing consumed as fuel in the blast furnace stoves, coke ovens, and the power station boilers. Continued 

compliance with the 326 lAC 7-4-14 S02 emission limits for these processes using blast furnace gas assures 

protection of the National Ambient Air Quality Standard for S02 regardless of the presence of an S02 emission 

limit for the blast furnace gas flare.
