5.                  Both records reviews and inspections were conducted for the Site by representatives of IDEM’s Office of Air Quality (“OAQ”) and the City of Indianapolis’s Office of Environmental Services (“OES”).  The following violations were in existence or observed at the time of these records reviews and inspections:

 

E/H BATTERY

 

a.                  Pursuant to 326 IAC 5-1-2(2)(A), opacity from a source or facility located in Marion County, Indiana, shall not exceed an average of thirty percent (30%) opacity in any one (1) 6-minute averaging period.

The Excess Emissions Reports, prepared by Respondent and submitted to IDEM, for Third and Fourth Quarters 2002; First, Second, Third and Fourth Quarters 2003; First and Second Quarters 2004; and First, Second, Third and Fourth Quarters 2005, for the E/H Batteries Underfire Stack demonstrated opacity in excess of thirty percent (30%) for at least one (1) 6-minute averaging period during each quarter, in violation of 326 IAC 5-1-2(2)(A).

Respondent contends that the circumstances described in Findings of Fact Paragraph No. 6 below and, in particular, Findings of Fact Paragraph No. 6(j), provide the factual background that explains and mitigates the issues related to the operation of the E/H Battery during the time periods discussed in Findings of Fact Paragraph No. 5(a). Respondent refers the reader to Findings of Fact Paragraph No. 6.

 

b.                  Pursuant to 326 IAC 11-3-2(f), oven door emissions requirements shall be as follows:  on and after July 1, 1982, no visible emissions shall be permitted from more than ten percent (10%) of the total coke oven doors, plus four (4) doors, on any coke oven battery.

On November 13, 2004, visible emissions from the coke oven doors on the E/H Batteries exceeded ten percent (10%) plus four (4) doors of the total coke oven doors on E/H Batteries operating ovens, in violation of 326 IAC 11-3-2(f).

On May 23 and July 23, 2005, visible emissions from the coke oven doors on the E/H Batteries exceeded ten percent (10%) plus four (4) doors of the total coke oven doors on E/H Batteries operating ovens, in violation of 326 IAC 11-3-2(f).

On November 26, 2005, visible emissions from the coke oven doors on the E/H Batteries exceeded ten percent (10%) plus four (4) doors of the total coke oven doors on the E/H Batteries operating ovens, in violation of 326 IAC 11-3-2(f).

Respondent contends these events were isolated, non-recurring events which had no systemic root cause that could be identified and addressed.  Respondent continues its program of door inspections and submittal of reports, which minimize the potential for further violations.

 

c.                  Pursuant to 326 IAC 11-3-2(b)(4), visible emissions from the charging system, including any open charge port, offtake system mobile jumper pipe, or larry car, shall be limited as follows: On and after July 1, 1982, such emissions shall not be visible for more than a cumulative total of one hundred twenty-five (125) seconds during five (5) consecutive charging periods.

On August 22, September 18, and October 27, 2004, charging emissions from the E/H Batteries were visible for more than a cumulative total of one hundred twenty-five (125) seconds during five (5) consecutive charging periods, in violation of 326 IAC 11-3-2(b)(4).

On five (5) days, from February 26, 2005, through July 25, 2005, charging emissions from the E/H Batteries were visible for more than a cumulative total of one hundred twenty-five (125) seconds during five (5) consecutive charging periods, in violation of 326 IAC 11-3-2(b)(4).

Respondent contends that issues with charging emissions arose at both batteries, in large part, as the result of the constantly changing coal supply discussed in Findings of Fact Paragraph No. 6 below and, in addition, less than optimum coal Respondent has had to purchase because of problems with its coal suppliers.  This new coal often has a higher percentage of coal fines.  The higher percentage of coal fines has two detrimental effects on charging emissions. First, additional fines get pulled off in the aspiration steam and plug up the goosenecks.  This carbon buildup, within the goosenecks, in turn blocks the flow of gases through the gas collection system during charging (as well as during the coking cycle).  As described in Findings of Fact Paragraph No. 7 below, Respondent has replaced the gooseneck cleaning equipment to achieve reductions in charging emissions.  Second, additional coal fines also cause coal to flow more slowly into the empty oven, which leads to longer-than-desired charging times and, therefore, a greater potential for exceeding the charging limits.  To mitigate the issues caused by additional coal fines, Respondent has, among other things, used additives that increase the flow rate of coal into the empty ovens.

 

BATTERY No. 1

 

d.                  Pursuant to 326 IAC 3-5, affected facilities are required to continuously monitor the applicable emissions.  The Respondent is required to continuously monitor opacity emissions at the E/H Battery Underfire Stack and at the Battery No. 1 Underfire Stack.

During the Fourth Quarter of 2002, the Respondent experienced opacity monitor downtime at the Battery No. 1 Underfire Stack, in violation of 326 IAC 3-5.

During the Third Quarter of 2005, the Respondent experienced opacity monitor downtime at the Battery No. 1 Underfire Stack, in violation of 326 IAC 3-5.

 

Respondent contends the following facts explain and mitigate the issues raised in Finding of Fact Paragraph No. 5(d): Opacity monitor down time in the Third Quarter 2005 relates to two occurrences on July 7 and 22, 2005, in which the calibration statistics relay board, and then the replacement board itself, failed. These boards are solid-state electrical units that, on average, last up to ten (10) years.  Two such boards failing in the same unit weeks apart is a rare occurrence and would not be predicted by the manufacturer or prevented through normal inspection and maintenance of the continuous opacity monitors (“COMs”).  The electronic nature of the relay boards made the problem difficult to diagnose. In spite of the difficulty involved, the problem was addressed in one (1) day in the first instance and within six (6) hours in the second instance.  In order to prevent maintenance-related costs and monitor down time, although the COMs have otherwise performed well, Respondent replaced the Battery No. 1 COMs in 2006.

 

e.                  Pursuant to 326 IAC 20-3-1(b), the air pollution control board incorporates by reference 40 CFR Part 63 Subpart L “National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coke Oven Batteries” 40 CFR 63.304 (b)(2) states, in pertinent part, that:

“…no owner or operator shall cause to be discharged or allow to be discharged to the atmosphere coke oven emissions from a by-product coke oven battery that exceed any of the following emission limitations:

 

6.         On or after January 1, 1998;

 

(i)                 For coke oven doors:

(A)              4.3 percent leaking coke oven doors for each tall by-product coke oven battery owned or operated by a foundry coke producer, as determined by the procedures in 63.309(d)(1);…

(ii)               0.4 percent leaking topside port lids, as determined by the procedures in 63.309(d)(1);

(iii)             2.5 percent leaking offtake system(s), as determined by the -procedures in 63.309(d)(1);…”

 

On sixteen (16) separate days from August 11 to October 22, 2002, the Respondent caused and/or allowed the discharge to the atmosphere of coke oven emissions exceeding 4.3% leaking coke oven doors for Battery No. 1, in violation of 326 IAC 20-3-1(b).

On July 23, 2005, the Respondent caused and/or allowed the discharge to the atmosphere of coke oven emissions exceeding 4.3% leaking coke oven doors for the No. 1 Battery, in violation of 326 IAC 20-3-1(b).

 

Respondent contends these were isolated, non-recurring events which had no systemic root cause that could be identified and addressed.  Nevertheless, Respondent continues to enhance its preventative maintenance program for the doors on Battery No. 1.  The table provided in Findings of Fact Paragraph No. 8 summarizes some of those efforts.

 

f.                    Pursuant to Prevention of Significant Deterioration (“PSD”) Approval No. PSD (49) 1209, Condition 4(c), Doors:  Self-sealing doors shall be provided to minimize leakage which shall include the following features:  A simple effective means of adjusting the doors sealing edges; The application of sufficient pressure to the door jambs by doors by the latching gear; The utilization of a block section jamb; Door and jamb cleaners in the mechanical reciprocating type designed to operate in conjunction with the actual arrangement and visible emissions from the doors shall be limited to 5% of all doors.

On ninety-six (96) separate days from April 14, 2001, through December 31, 2003, and eighteen (18) separate days from July 24, 2004, through January 30, 2005, visible emissions were observed from more than 5% of the total coke oven doors on Battery No. 1 operating ovens, in violation of PSD Approval No. PSD (49) 1209, Condition 4(c).

On twenty three (23) separate days from January 15, 2005, through August 25, 2005, visible emissions were observed from more than 5% of the total coke oven doors on Battery No. 1 operating ovens, in violation of PSD Approval No. PSD (49) 1209, Condition 4(c).

On ten (10) separate days from September 3, 2005, through December 31, 2005, visible emissions were observed from more than 5% of the total coke oven doors on Battery No. 1 operating ovens, in violation of PSD Approval No. PSD (49) 1209, Condition 4(c).

Respondent contends the following explains and mitigates the issues raised in this Findings of Fact Paragraph No. 5(f):  In addition to the additional preventative maintenance tasks described in Respondent’s response to Findings of Fact Paragraph No. 5(e) above (which will likely continue to improve operations at the doors), Respondent believes the 5% permit limit referenced above is not a proper, lawful, or achievable limit for the Battery No. 1 doors.  At the time the 5% permit limit was imposed, Respondent is unaware of any other coke oven battery that achieved the limit without an exception in the limit for recently-charged doors. Respondent’s permit does not include this exception.  Respondent has accordingly filed, on April 13, 2006, a request with IDEM to modify this permit term.

These issues are being addressed through the compliance schedule in Order Paragraph No. 3.

 

g.                  Pursuant to 326 IAC 11-3-2(b)(4) visible emissions from the charging system, including any open charge port, offtake system mobile jumper pipe or larry car shall be limited as follows: On and after July 1, 1982, such emissions shall not be visible for more than a cumulative total of one hundred twenty-five (125) seconds during five (5) consecutive charging periods.

On October 28, 2004, and November 7, 2004, charging emissions from the Battery No. 1 were visible for more than a cumulative total of one hundred twenty-five (125) seconds during five (5) consecutive charging periods, in violation of 326 IAC 11-3-2(b)(4).

On four (4) separate days from May 14, 2005, through August 15, 2005, charging emissions from Battery No. 1 were visible for more than a cumulative total of one hundred twenty-five (125) seconds during five (5) consecutive charging periods, in violation of 326 IAC 11-2(b)(4).

On November 26, 2005, charging emissions from Battery No. 1 were visible for more than a cumulative total of one hundred twenty-five (125) seconds during five (5) consecutive charging periods, in violation of 326 IAC 11-3-2(b)(4).

Respondent contends that the coal fines issues discussed in connection with Findings of Fact Paragraph No. 5(c) above apply with equal force to, and help explain and mitigate, this claim.

 

BY-PRODUCTS RECOVERY PLANT

 

h.         Pursuant to PSD Approval No. (49) 1209, to meet the requirements of the Act that the Lowest Achievable Emission Rate for sulfur dioxide be met, the gas from the coke oven shall be desulfurized.  Gas used for under firing the oven shall not exceed 20 grains H2S/100 standard cubic feet (“scf”).  Gas intended for distribution shall be further cleaned so that the average of all gas produced by the new battery will have no more than 10 grains H2S/100 scf.

On one hundred thirty five (135) separate days from March 26, 2001, through December 31, 2003, H2S in the coke gas from No. 1 Battery exceeded 20 grains H2S/100 scf of coke oven gas, in violation of PSD Approval No. PSD (49) 1209, Condition 5.

The Respondent contends the following facts explain, mitigate, and put this issue into perspective:  Historically, Respondent relied upon the iron oxide system at the Site to desulfurize coke oven gas which generated a spent iron oxide that had to be sent off-site for disposal.  Occasionally, testing of this material indicated it was a hazardous waste.  To reduce hazardous waste generation, Respondent investigated using a new desulfurization technology, and ultimately identified the vacuum carbonate technology from Germany (commonly referred to as a “Claus” system). Although no similar desulphurization plant existed at a coke plant in the western hemisphere, this technology had been successfully implemented in Europe.

In 1992, engineering design began for a $27 million desulphurization complex. Start-up was completed in August 1994.  The contract with the vendor called for 95% availability of the desulphurization complex.  Through June 2001, operating time had averaged only 55%.  A series of design and operational problems caused Respondent to spend approximately $2 million dollars to keep the system running. Despite having what was believed to be a state-of-the-art desulphurization complex, both the desulphurization plant (to clean the gas down to 20 to 30 grains of H2S/100 scf), and, in addition, the oxide boxes were required to reduce H2S to less than 20 grains of H2S/100 scf.

Eventually, Respondent decided to shut down the desulphurization complex in the summer of 2002 and to rely solely on the oxide box technology.  At the same time, Respondent developed a nitrogen purge system that would avoid the generation of spent oxide chips as a hazardous waste.  Although Respondent had used the oxide box technology successfully prior to 1994, and intermittently from 1994-2002, operational difficulties experienced in the first several quarters of return to full operation resulted in exceedances of the H2S limit during that time.  Oxide box operational problems were addressed and since December 2004, Respondent has been in continuous compliance with the 20 grains H2S/100 scf of coke oven gas requirement.

 

6.         The Respondent contends the following facts and circumstances provide an explanation and partial mitigation of the above-cited violations:

 

a.         Beginning in the late 1990s, importation of foreign government-subsidized coke at below-market prices substantially drove down the price of domestically produced coke. The resulting decrease in revenue impaired domestic coke suppliers and threatened the long-term viability of Respondent’s coke plant and many of its merchant plant competitors.  The market depression began to turn around in 2003 after the U.S. Congress intervened and placed import tariffs on imported coke.

 

b.         Between August 2000 and March 2004, twelve (12) of Respondent’s foundry customers filed bankruptcy.  The resulting loss in income to the Respondent from the debts discharged in these bankruptcies was $1.7 million.  Beyond that loss, these customers represented approximately ten percent (10%) of the coke plant’s production, or approximately $8.5 million in annual sales.

 

c.         The coke plant lost $87.7 million during the period 2001-2004.  The coke plant’s cash operating loss for the twelve (12) months ending July 31, 2006, was $20.8 million.

 

d.         In December 2001, LTV Steel, Respondent’s largest customer with about 40% of the plant’s production, declared bankruptcy.  In addition to the financial loss of $2.5 million in discharged debt, Respondent had no customer to sustain continued production of blast furnace coke at the E/H Batteries.

 

e.         As result of lost business, beginning in January 2002, Respondent put the E/H Batteries into “hot idle” mode until economic conditions could improve.  The ovens were kept closed and empty, with a minimum amount of heat provided to avoid the most damaging effects of a complete cool down.  A complete cool down would have required permanent closure of the E/H Batteries.

 

f.          Based on previous experience, Respondent believed that no significant damage would occur to the ovens as a result of the hot idle.

 

g.         The hot idle caused more substantial damage to the batteries than expected, as described in Findings of Fact Paragraph No. 6(j) below.  The various items of damage, in turn, adversely affected battery operation and emissions. Appendix A (attached hereto and incorporated by reference) describes the maintenance and repair activities performed by Respondent at the E/H Batteries before and after the hot idle to return these batteries to good working condition.

 

h.         Respondent had to lay off eighty-five (85) experienced coke battery employees as it went into hot idle.  Only approximately twenty (20) of these employees ultimately returned to work at the Site.

 

i.          The E/H Batteries returned to production in June of 2002 when a new coke contract was secured, although the new contract was at a low price, below Respondent’s production costs at the time.

 

j.          After returning to production following the 2002 hot idle, Respondent experienced problems at the E/H Batteries in the following areas:

 

i.          Prolonged and extreme temperatures decarbonized the oven walls and led to burned out standpipes and warped or broken steel tie rods, resulting in wall separation and cracking;

 

ii.         An early retirement program led to a loss of significant experience and expertise at all staffing levels, including oven operators and troubleshooters; and

 

iii.        Coal supply and market problems caused fluctuations in the oven schedule upon the return to production.

 

k.         The following circumstances have contributed to the opacity exceedances at the E/H Batteries Underfire Stack:

 

i.          Interruptions in production reduced carbon accumulation and increased cracking and other damage to the ovens.

 

ii.         Significant changes in available coal types and quality resulted in an erratic production schedule, which in turn caused damage, including “sticker” ovens.

 

l.          In summary, beginning in the 1990s, subsidized imported coke artificially reduced prices and threatened the entire domestic coke industry including Respondent.  In addition, Respondent lost several major customers from bankruptcies in the period 2000-2004.  These two factors, beyond Respondent’s control, led to a very substantial loss of business and revenue, and to Respondent losing nearly $90 million in the period 2001-2004.  These economic conditions led to the E/H Battery hot idle in 2002.  Unlike a previous return to production following a hot idle in the 1980s, the 2002 hot idle caused more substantial damage to the E/H Batteries than expected, which in turn led to increased emissions while Respondent has, at a cost of $4 million, taken steps to repair the damage.  Those efforts are now complete. However, continued post-2002 disruptions to Respondent’s coal supply, both in terms of quantity and quality, and continued loss of customers have hampered Respondent’s recovery efforts and adversely affected production cycles, which in turn adversely affects battery operation and emissions.

 

7.         In addition to the maintenance and repair activities listed in Appendix A, Respondent further contends it has taken the following steps to address opacity emissions exceedances at the E/H Batteries underfire stack:

 

a.         Pusher-side end flue repairs have been completed on oven wall numbers E8, E9, E10, E11, E12, E13, E14, E15, E16, E17 and E18;

 

b.         Pullman valves have been modified to prevent them from closing on their own and forcing coke oven gas out through the flues;

 

c.         The “Wobbe” system was upgraded in late 2005.  This system allows BTU delivery to be adjusted for a specific battery to normalize the BTU delivery rate and to make specific adjustments in response to an opacity issue;

 

d.         The E Battery gas burners were re-piped in October 2005.  This provides both for a steady gas flow, critical for reducing baseline opacity, and prevents further degradation of the burners, which would otherwise lead to additional leakage;

 

e.         The gooseneck is a bent section of pipe that connects the vertical standpipe to the horizontal gas collector main.  Carbon tends to build up in this section of pipe and restricts the flow of gas from the vertical standpipe to the horizontal gas collector main.  To relieve this problem, Respondent   has taken the following steps:

 

i.          A new pump has been placed into operation to supply the high pressure stream of water that spins the cleaning head inside the gooseneck.

 

ii.         Structural modifications have been made to the goosenecks.

 

8.      Respondent has taken the following steps to enhance the preventive maintenance program associated with the doors on Battery No. 1:

9.                 In 2004, Respondent voluntarily agreed to provide Mostardi-Platt Environmental ("MP"), a contractor hired by IDEM, full access to Respondent's coke making facility, records, and personnel to allow MP to perform an evaluation of operations at the facility for the purpose of identifying possible measures that could be taken to further improve environmental performance at the facility above and beyond what is required by law.

The resulting February 1, 2005 report (the "MP Report") contained a number of possible actions that could be taken at the Facility for further evaluation by Respondent and IDEM. Both IDEM and Respondent have carefully studied and evaluated the recommendations and suggestions contained in the MP Report during the process of developing this Agreed Order.  Respondent had already implemented a number of actions consistent with the suggestions in that report prior to release of the report, and some of the actions described in and to be taken pursuant to this Agreed Order are consistent with other suggestions from the report.

 

10.      A modern data logger and data acquisition and handling system has been installed by Respondent at the Site for compliance with the opacity monitoring requirements of the Pushing Quench Battery Stack NESHAP that should fully address data loss from software system failures.

 

11.      During 2002, Respondent shut down the Desulphurization Complex and began using oxide box technology to desulfurize coke oven gas.  Since December 2004, the Respondent has been in continuous compliance with the 20 grains H2S/100 scf of coke oven gas requirement.

 

12.      Beginning on August 1, 2002, the Respondent has maintained the required records of routine maintenance activities for the air pollution control devices at the Site.

 

13.      This Agreed Order resolves the violations cited in the City of Indianapolis’ Notice of Violation, dated February 26, 2004.

 

14.      The E/H Underfire Stack was in compliance with 326 IAC 5-1-2(2)(A) for the 1st and 2nd Quarters of 2006.

 

15.      In recognition of the settlement reached, Respondent waives any right to administrative and judicial review of this Agreed Order.

 

II.  ORDER

 

1.         This Agreed Order shall be effective ("Effective Date") when it is approved by the Complainant or his delegate, and has been received by the Respondent.  This Agreed Order shall have no force or effect until the Effective Date.

 

2.         Upon the Effective Date of this Agreed Order, Respondent shall comply with IC 13-30-2-1, 326 IAC 5-1-2(2)(A), 326 IAC 3-5, 326 IAC 20-3-1(b), 326 IAC 11-3-2(f) and 326 IAC 11-3-2(b)(4).

 

3.         IDEM concludes that Respondent cannot immediately achieve compliance with the limit of 5% leaking doors (“5 PLD”) set out in Permit No. PSD (49) 1209.  Therefore:

 

a.                  Respondent shall comply with the following requirements:

 

i.                    As requested by IDEM’s response to Respondent’s April 13, 2006 permit revision application, Respondent shall submit a Lowest Achievable Emissions Rate (“LAER”) analysis to IDEM for PM10 which contains Respondent’s evaluation of the appropriate PLD limit for Battery No. 1 no later than twenty-four (24) months following the Effective Date of this Agreed Order.  This LAER analysis shall not require a redesign of Battery No. 1.  The limit recommended in this LAER analysis shall have been demonstrated to be achievable in practice, and shall be appropriate for Battery No. 1, taking into account its size, age, and other unique physical and operating characteristics.  Nothing in this Agreed Order shall act as a waiver of Respondent’s ability to later challenge the applicability of the 5 PLD limit.

 

ii.         By no later than twenty four (24) months following the Effective Date of this Agreed Order, Respondent shall also submit an analysis of “best practices to reasonably minimize emissions from leaking doors on coke batteries.”  This analysis shall be developed by, among other things, surveying other coke manufacturing facilities (to the extent allowed by these facilities) that are of comparable design and operating characteristics to Battery No. 1.

 

iii.        To further minimize emissions during this 24-month period, Respondent shall implement the additional door maintenance practices at Battery No. 1 described below:

 

A.        Enhanced Training Program - An enhanced training program will be initiated within four (4) months of the Effective Date of this Agreed Order.  The program shall be designed and implemented by internal and/or external personnel and will include the following components:

Refresher training on procedures, work instructions, equipment design, and regulatory requirements related to compliance with environmental requirements for Battery No. 1 door leaks.

Personnel to be trained include all battery shift supervision, battery operations personnel (machine operators and chargers), environmental utility personnel, and environmental repair personnel.

A key component of the training program shall be evaluation and feedback.  EPA Method 303 data shall be used to compare performance of individual work crews before and after the initial training sessions.  The resulting information shall then be used to focus subsequent training on subject matter and personnel where the data suggest the greatest opportunity for additional positive impact is available.

APPENDIX C

CORRECTIVE ACTION PLAN

DAMAGED AND LEAKING BRICKWORK-E/H BATTERY

 

 

This Damaged and Leaking Brickwork –E/H Battery Corrective Action Plan shall be implemented until compliance with opacity regulations has exceeded 97% for at least four (4) consecutive quarters, beginning with the first calendar quarter following the adoption of this Agreed Order.

 

1.                 Inspections:  Respondent shall perform inspections of the battery twice per year to determine the necessity for brickwork repair.  After each inspection, repair work shall be prioritized and performed in such a manner that the worst areas will be addressed first, weather permitting, unless Respondent determines that another prioritization is appropriate based on the results of the inspection.  Repair activities shall include, but are not limited to, silica dusting, patch & spray, panel patching/ceramic welding, tie rod replacement, and end flue replacement (zero expansion modular type).

Respondent shall keep a record of all planned inspection and maintenance activities intended to control underfire stack emissions which could result in excessive loss of oven sealing carbon and subsequent brief periods of stack visible emissions.  Each record shall include:

 

a.      the date of the outage;

 

b.      battery name;

 

c.      oven number;

 

d.      time that the oven was last pushed;

 

e.      time that the oven was subsequently charged;

 

f.        the reason for the outage, and;

 

g.      the repair scheduled or performed.

 

2.                  Silica Dusting:  Respondent shall dust one (1) oven per day, three (3) days per week, weather permitting, unless there is other, higher priority repair work, as determined by Respondent, in progress.

 

3.         Patch and Spray:  Respondent shall perform a P&S repair on oven doorjambs on an as-needed basis for minor repairs.

 

4.         The Respondent shall submit a copy of the above-referenced records to IDEM on a monthly basis.  In addition, all records shall be retained a minimum of five (5) years.

 

Description of Types of Repairs-These descriptions are not intended to set out additional requirements to those above but simply to provide background information on the types of repairs referenced above.

 

1.         Silica Dusting relies on the pressure differences between an empty oven, which is at atmospheric pressure, and the heating flues, which are under negative stack draft, to carry the fine silica dust particles into small cracks in the oven walls.  Large cracks will permit the silica dust to pass through directly into the flues, so they must first be sealed by patching.  The silica dust is aspirated to a discharge pipe located below the charging hole. A valve controls the rate of dusting so that the dust will be distributed evenly throughout the oven chamber.  The procedure can take most of a shift to complete.

 

2.         Patch and Spray repair entails troweling a mortar mixture on large cracks (>1/8" wide) on the end flues to seal the cracks and to prevent raw coke oven gas from entering the flue system and causing excess opacity. The end flue area is then sprayed to fill smaller cracks in the brickwork.

 

3.         Panel Patch:  Panel patching is done by removing and replacing a section of brickwork on one end of an oven at a time.  The oven to be repaired and the ovens immediately adjacent to it are taken out of service to perform this repair.  After the oven door is removed, loose material at the end flue area is raked out and the oven is scraped to remove scaling, loose mortar, and carbon.  The deteriorated brick is removed and replaced with special "zero expansion bricks."  Gaps are trowel-patched the area is sprayed with a mortar slurry and the excess is removed by a scraper before the material sets up. After the patching work has been completed, the walls and end flues are inspected.

 

4.         End Flues/Throughwalls:  End Flue replacement is accomplished by removing and replacing the brickwork with zero expansion modular panels for the entire height of the battery from the battery bench to the first several heating flues, and is performed on one end of an oven at a time.  A throughwall is a complete rebuild of an internal heating wall. Once a repair oven and the adjacent ovens are removed from service, insulation is placed on the surrounding heating walls to minimize heat loss.  The designated brickwork is then removed and replaced.

 

5.         Tie rod replacement:  Respondent has an on-going program of tie-rod inspection and replacement. Joints in the brickwork will expand if a tie-rod breaks.  A repair is accomplished by stabilizing the battery brickwork with chains across battery width that attach to buckstays.  The broken tie-rod is then removed and replaced.

 

 

APPENDIX D

GAS SUPPLY WASTEWATER COLLECTION PROJECT

 

 

Current Situation and Status: Coke oven gas from the batteries is cleaned or conditioned in a “conditioning facility” that removes water and some trace constituents from the coke oven gas prior to transport via pipeline to the Perry K steam generating plant. The water and trace constituents (which include benzene) are collected in open vessels and are then piped to the biological wastewater pretreatment system at the Coke plant. The Mostardi-Platt report identified the treatment of this water in this system as a potential source of benzene emissions. Citizens estimates that up to 10,000 lbs. of benzene per year are present in this wastewater. This source is located near the plant property line closest to School 21.

Citizens has identified seventy-two (72) wastewater streams with potential benzene emissions in the Gas Supply Wastewater collection system.  Of the seventy two wastewater streams, four of them account for approximately eighty two percent (82%) of the benzene emissions.  Citizens is proposing a system for collecting and destroying the benzene from these four (4) significant benzene sources.

The remaining sixty-eight wastewater streams represent less than eighteen percent (18%) of the total benzene present.  These sixty-eight sources are widely scattered throughout the facility which covers approximately forty (40) operating acres.  Each of these wastewater streams accounts for less than three (3) pounds of benzene per day.  In fact, most of these wastewater streams contain less than 0.1 pounds per day.

 

Project: Citizens could install hard piping to transport the condensed water from the current coke oven gas condensate collection and storage tank to the H Battery flushing liquor system instead of sending this condensate to the biological treatment system. The condensate would be sent to the flushing liquor system where it would not be exposed to the atmosphere and would be destroyed in the ammonia stripping and destruction system. While not part of the scope of the Mostardi-Platt recommendations, other trace constituents in the condensed water, such as naphthalene, xylene, and toluene, would be destroyed as well. The destruction system operates at approximately 2000oF and would quickly combust the benzene and other hydrocarbons. The “tail gas” from this destruct process is directed back to the coke oven gas system where it is beneficially reused.  Nearly 1,000 feet of carbon steel stream traced/insulated piping with support structures would be required to divert this wastewater to the destruct system. Some of the piping would run underground and would be constructed of stainless steel. The section that crosses Pleasant Run Creek would be double wall pipe.

Environmental Benefit: This project would eliminate up to 10,000 pounds of benzene emissions per year as well as other volatile organic compounds found in coke oven gas condensate. An added benefit is that this current open-aired operation is located on plant property relatively close to the public and to School 21.

Estimated Cost and Timing: Although detailed engineering has not been completed, the preliminary estimated capital cost would be about $150,000. We estimate that once final plans and specifications would be complete and the project bid, construction and final testing would take approximately 6 to 8 months. Maintenance and operation cost would be about $60,000 per year. The primary component of the operating cost would be the additional steam required at the stripping unit prior to destruction. Other on-going costs would include maintenance of the system as well as steam tracing costs.

 

APPENDIX E

E&H BATTERY MODULAR END FLUE REPLACEMENTS-BEYOND COMPLIANCE

 

 

Current Situation and Status:  A number of the E&H Battery oven refractory end flues have open joints. The open joints are caused by the thermal shock of heat loss when the oven doors are removed. When the refractory brick joints open, the gas from the coking process can escape from the oven chamber through the open joints into the adjacent heating flues and then out the main stack.  This leakage can increase stack opacity. In addition, when the raw gases leave the oven chambers into the heating flues, excessive combustion occurs and further damages the brickwork.

The stability of the oven walls can also be adversely affected by the necessary purchase of “spot coal” that is not the same high quality as Citizens’ normal sources, and which occasionally does not shrink as much, thereby exerting excessive pressure on the oven walls during the push causing further brick movement.

Project:  Citizens is in the process of replacing refractory brickwork on several pusher side end walls, six flues deep into the ovens with a new masonry technology of modular, zero expansion refractory. This refractory sustains the structural integrity of the wall throughout the coke oven cycles of thermal shocks. The modules do not allow gases from the oven chambers to escape into the adjacent heating flues.  This Project includes end flue replacements beginning January 1, 2006, and will include at least eleven (11) single-wall end flue replacements that are not needed to achieve compliance.

Environmental Benefit:  End flue replacements reduce stack opacity emissions by not allowing coke oven gases to escape out of the ovens into the flues and on to the underfire stack. They also reduce emissions by eliminating further damage to ovens that can lead to emissions. The replacement of the end flue walls will also allow the ovens to be fully charged and will help normalize coke oven operations. This stability in the process will allow the ovens to form “good carbon” which helps seal the small joints in the refractory resulting in even further reduced emissions.

Over the first half of 2006, Citizens performed replacement of the end-flue brickwork at E/H Battery.  As has been described in other submittals, the end-flue replacements reduced average stack opacity from approximately 14.4% to 13.4%.

There is significant uncertainty about the specific mass emissions associated with a particular level of stack opacity.  The United States Environmental Protection Agency (“U.S. EPA”) attempted to estimate extractable organic emissions, as a surrogate for coke oven emissions, associated with particular opacity levels, through a formula based on tests the agency conducted at ABC Coke, in Birmingham, AL, as discussed in the Final Report for the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coke Ovens: Pushing, Quenching, and Battery Stacks (published February 2001).  Within that report, U.S. EPA created a formula to create estimates for other coke oven batteries based on the test results from ABC Coke, as follows:

0.22 lb/hr x actual average opacity/1.7% x [actual stack exhaust flow rate/83,000 ACFM].  See, p. 5-14.

U.S. EPA’s estimate, because it was based on testing at a single facility, cannot be uniformly applied to all coke oven batteries.  However, if the average daily opacity was reduced at ABC Coke by 1%, as occurred after the end-flue repairs at the Citizens facility, and U.S. EPA’s formula was used to adjust for the stack flow rate associated with E/H Battery, then that formula would predict the extractable organic emission reduction to be 683 lbs. per year, as follows:

0.22 x (14.4 – 13.4) / 1.7 x [50,000 / 83,000] x 8,760 hours/year = 683 lbs.

Estimated Costs and Timing:  The total time to complete a double wall end flue replacement is about six weeks.  A double end flue module installation is two walls side by side and their roof. To accomplish a double wall end flue repair, the two adjacent ovens must be taken out of service, and two additional ovens on either side must be put into a reduced heating mode.  The cost of each double wall end flue replacement is about $120,000.

 

APPENDIX F

BENZENE REMOVAL THROUGH POWERHOUSE TANK BLANKETING

 

I.                    Current Situation: A naphthalene scrubber is operated to remove naphthalene from the coke oven gas, creating an enriched fuel product.  The naphthalene is absorbed by No. 2 fuel oil sprayed onto the gas.  A number of other hydrocarbons, including benzene, are also absorbed, although to a much lesser extent.  The resulting enriched fuel oil is stored in a tank called the “Powerhouse Tank,” which is vented to atmosphere. The oil is sold and shipped off-site to customers.

II.                   Project: Citizens could seal the Powerhouse Tank so that it is not vented to atmosphere and install a blanketing system. Storage tanks that are vented to the atmosphere “breathe” out vapors during filling operations and “breathe” in air during emptying operations. A blanketing system is used for sealed tanks so that they can continue to “breathe”. Vapors pushed out of the tank during filling operations would be captured by the blanketing system. Also, the blanketing system would provide nitrogen gas to fill the tank during emptying operations. The role of the blanketing system is to maintain a constant pressure in the vapor space of the tank. The blanketing system would consist of a pressure regulated nitrogen supply to the tank and a stainless steel vent pipe with pressure control valve that would carry away tank vapors to the coke oven gas main. The introduction point of the vapors would be located upstream of the exhausters and would be under vacuum. The tank could be equipped with pressure/vacuum relief valves so that the tank would be protected against pressures outside of design limits in case the blanketing system fails or from some other upset condition.

III.                 Environmental Benefit: The Mostardi-Platt report identified the Powerhouse Tank as a potential source of organic emissions. Mostardi-Platt recommended that this tank be blanketed if it had a high organic content. We estimate that approximately 18,000 pounds of benzene are stored in the tank per year but only a fraction of this amount could be emitted to the atmosphere. Clearly, some of the benzene is emitted along with other VOC’s as the tank breathes.  This project would eliminate the venting of benzene and other VOC’s from the Powerhouse Tank to the atmosphere.

IV.               Estimated Cost and Timing: Although detailed engineering has not been completed, the preliminary estimated capital cost would be about $300,000.  Maintenance and operation cost is estimated to be $12,000 per year. The primary component of this cost is for maintaining the steam tracing for the vent pipe and the steam heater for the nitrogen service.  We estimate that once final plans and specifications would be complete and the project bid, construction and final testing would take approximately 7 to 9 months.

 

 

APPENDIX G

BENZENE REMOVAL THROUGH VAPOR RECOVERY FOR TAR LOADING

 

 

I.                     Current Situation:  Coal tar is manufactured through the coke making process. Citizens manufactures approximately 5 million gallons of coal tar per year.  The coal tar is stored in tanks from which it is loaded into trucks and rail cars by splash loading and sold to customers.  Although coal tar storage tanks are sealed from the atmosphere with the use of tank blanketing systems, vapors generated during the splash loading operation are released to the atmosphere.

II.                   Project: Consistent with Mostardi-Platt recommendations, Citizens could install a vapor recovery system that would capture the majority of any vapors generated during loading. Such a system could consist of ducting that would enclose the openings in the tanker truck and would direct the vapors to a scrubber.  The vapors would be drawn into the scrubber with either an ejector-venturi or a blower. Fuel oil that would be circulated in the scrubber would absorb the hydrocarbons in the vapors. The cleaned vapors would exhaust to atmosphere. A mist eliminator would be installed in the scrubber to prevent the discharge of oil to the atmosphere.

III.                  Environmental Benefit: It is estimated that this capture system would eliminate approximately 80% of current hydrocarbon emissions. We estimate that 800 lbs. benzene, 400 lbs. naphthalene, 400 lbs. toluene, and 100 lbs. xylene would be captured annually.

IV.               Estimated Cost and Timing: Although detailed engineering has not been completed, the preliminary estimated capital cost would be about $100,000. Maintenance and operation cost would be about $8,000 per year. Pump maintenance would be the primary cost.  We estimate that once final plans and specifications would be complete and the project bid, construction and final testing would take approximately 6 to 8 months.

 

 

APPENDIX H

HANDHELD LEAK DETECTION AND REPAIR (LDAR) IMAGING CAMERA

 

 

I.          Current Situation:  Sources of Volatile Organic Compounds (VOCs) in Indiana are required to implement Leak Detection and Repair (LDAR).  Currently, leak detection is performed with the use of portable air monitoring equipment.  A technician draws an air sample from each piece of equipment that has the potential to leak.  This is a relatively slow, labor intensive and frequently inaccurate method.  In     addition, it is very difficult for regulatory agencies to verify compliance with LDAR requirements.

 

II.          Potential Project: Respondent proposes providing IDEM with the funds to purchase a ThermaCAM GasFindIR Camera (“ThermaCAM”) leak detection infrared imager.  The ThermaCAM has the capability to quickly scan large areas of a facility for leaks.  IDEM staff will use the ThermaCAM to verify compliance with LDAR requirements.  In addition, there is the potential for reducing VOC emissions by locating previously unidentified leaks and having them repaired.

 

III.         Estimated Cost and Timing: The cost of a ThermaCAM and the relevant accessories is approximately $100,000.00.  This Project shall be completed no later than December 31, 2006.

 

 

APPENDIX I

EXPANDED COLLECTOR MAIN CLEANING

 

 

I.          Current Situation: The collector main must have clear passages to allow for stable pressurization of the battery.  Unstable pressurization leads to periods of over-pressurization which can cause door leaks.  Traditionally, Citizens has cleaned the collector main up to two times per year.  With changes in available coal supply and additional coal fines included in the current coal mix on a regular basis, performance would likely be enhanced with additional cleaning of the collector main.

 

II.          Project: Clean the collector main an additional time each year (three (3) times per calendar year) for the next five (5) years, beginning in calendar year 2007.

 

III.         Environmental Benefit: This project will assist in lowering the pressure in the coke ovens and in             preventing coke oven gas from leaking through the doors during coking.

 

V.                 Estimated Cost and Timing: This task can cost up to $40,000 per iteration.

Respondent proposes investing in Southeast Neighborhood Area community projects described below.  These dollars are intended for areas in and around the Southeast Neighborhood Area, the Southeast Community Organization and IPS McFarland Environmental Studies Magnet School.

 

Program Investments will include:

 

A.        Southeast Community Organization youth Programs

 

Through the community center and neighborhood organization, there are several youth programs designed to keep young people engaged in meaningful activities while they are not in school.  Activities to be funded would include neighborhood clean-ups, beautification, and recycling projects.  Funds would be administered by the Southeast Community Organization (“SECO”).

 

$10,000.00

 

B.        Kids and the Environment

 

The Boy Scouts and Girl Scouts offer day and residential camp experiences during the summer for young people to learn about the environment and the out of doors.  The focus of the camps is to examine how plants and animals live in harmony with the environment and why it is important for humans to protect and care for our environment.  The young people learn ways to keep our homes clean without harming the environment, they learn to recycle and they explore ways to reduce heating cost.  This camp offers the young people an understanding of ways to make our home (Earth) a better place for all.  For many urban families, cost is a barrier to participation.  This initiative would provide 100 girls and 100 boys from the southeast area a scholarship to attend Boy Scout camp or Girl Scout camp.  These young people could be selected from youth currently in scouting programs in the neighborhood and/or from youth participating in programs with the Southeast community organization.  Funds will be administered by Girl Scouts of Hoosier Capital Council ($20,000.00) and Crossroads Council, Boy Scouts of America ($20,000.00).

 

$40,000.00

 

C.        McFarland Middle School Environmental Studies Magnet Program

 

The emphasis of the environmental studies curriculum at McFarland is environmental stewardship.  The school has the largest biodome of its kind in the city.  Funds would be used to develop the biodome into different habitats that represent various ecosystems and climates as well as the necessary curriculum that supports the project.  Funds could also be used to expand current programming and student experiences in the environmental studies programs.  Funds would be administered by the IPS Education Foundation.

 

$30,000.00

 

D.        The mayor has launched a new initiative to focus on the quality of life in six designated areas, including the southeast area.  These areas will receive city funding and staff over the next three years.  As with most city initiatives, there will be a need for private sector dollars to fund parts of the initiative.  The investment in this initiative is designated for park improvements, public right of way beautification, or other environmental projects that are identified during the initiative’s planning process.  Funds will be administered by Local Initiative Support Corporation (LISC).

 

$20,000.00
