Section 9-3 - Emission limitations

Universal Citation: 326 IN Admin Code 9-3

Current through March 20, 2024

Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11

Affected: IC 13-15; IC 13-17

Sec. 3.

With the exceptions noted in this section, the coke batteries in Lake County shall comply with the following emission limits by December 10, 1993:

(1) Single-pass cap for oven door emissions. No visible emissions shall be permitted from more than ten percent (10%) of the observed coke oven doors on any coke oven battery. The number of coke-side doors and push-side doors shall be counted in determining compliance with this emission limit. Doors of ovens that are out of service, either temporarily or permanently, shall not be counted. A push door and a chuck door shall be counted as one (1) door. Compliance with this emission limit shall be determined in accordance with the procedure described in 326 IAC 11-3-4(c).

(2) Charging emissions. No visible emissions shall be permitted from the charging system for more than a cumulative total of one hundred twenty-five (125) seconds during five (5) consecutive charging periods. For the purpose of this subdivision, "charging system" means the equipment required to add coal to a coke battery. This includes:

(A) a larry car;

(B) charge ports;

(C) jumper pipe; and

(D) offtake pipe.

Compliance with this emission limit shall be determined in accordance with the procedure contained in 326 IAC 11-3-4(a).

(3) Pushing emissions. The following emission limits shall apply during pushing operations:

(A) The opacity of emissions from the coke-side of an oven to be pushed, before the first movement of the coke from the oven to the coke car begins, shall not exceed twenty percent (20%). The opacity shall be determined on an instantaneous basis at the top of the battery. The observer shall be positioned outside of the quench car rails.

(B) The opacity of emissions during the pushing operation shall not exceed twenty percent (20%). The pushing operation shall be considered to:
(i) begin with the first movement of coke from the oven into the coke car; and

(ii) end when the quench car enters the quench tower. The opacity shall be determined using 40 CFR 60, Appendix A, Method 9*, except that the readings shall be taken at fifteen (15) second intervals. Six (6) consecutive readings shall be averaged to determine the opacity. The observer shall only use those backgrounds that are above the elevation of the battery surface. If this condition cannot be met for six (6) consecutive readings, then the opacity shall be determined using the lesser number of consecutive readings.

(C) The particulate emissions from the control device stack shall not exceed four-hundredths (0.04) pound per ton of coke pushed. Compliance with this emission limit shall be determined by 40 CFR 60, Appendix A, Method 5*.

(4) Charge port lid emissions. No visible emissions shall be permitted from more than three percent (3%) of the total charge port lids on operating ovens of a coke oven battery. Compliance with this emission limit shall be determined in accordance with 326 IAC 11-3-4(b).

(5) Offtake piping emissions. No visible emissions shall be permitted from more than five percent (5%) of the total offtake piping on any coke oven battery. At no time shall the visible emissions from any gooseneck cap opening exceed twenty percent (20%). An exclusion from this opacity limit shall be allowed for two (2) minutes after a gooseneck cap is opened. The opacity shall be determined on an instantaneous basis. Compliance with this emission limit shall be determined in accordance with 326 IAC 11-3-4(b).

(6) Gas collector main emissions. No visible emissions shall be permitted from the gas collector main. Compliance with this emission limit shall be determined in accordance with 326 IAC 11-3-4(e). Caps on the main shall be exempt from this requirement during maintenance.

(7) Quenching emissions at U.S. Steel-Gary Works. At a minimum, the following procedures and practices shall be followed:

(A) The quench water, as applied to the coke, shall not exceed one thousand five hundred (1,500) milligrams per liter dissolved solids.

(B) A source shall submit the following information regarding its quenching operation in its CCP required to be submitted by 326 IAC 6.8-8-1:
(i) The source of quench water, for example, Lake Michigan water only, or a mixture of Lake Michigan water, spent quench water, process water, and miscellaneous sources of nonprocess water.

(ii) The volume of quench water and the proportion of each source of water.

(C) All coke oven towers shall be equipped with baffles. Baffles shall cover ninety-five percent (95%) or more of the cross-sectional area of the exhaust vent or stack for straight quench towers and must be maintained in operable condition. For offset quench towers numbers 2 and 3 at U.S. Steel-Gary Works, the number and arrangement of baffles in the tower shall be maintained as designed. The source shall submit quench tower drawings showing baffle arrangement to the department and the U.S. EPA on or before December 10, 1993. Compliance with the quench tower baffle requirement shall be determined by comparison of the number and arrangement of baffles with the submitted plans.

(8) Underfire emissions requirements shall be as follows:

(A) Particulate emissions from underfire stacks shall be limited by the emission limitations contained in 326 IAC 6.8-2.

(B) Visible emissions from underfire stacks shall comply with the requirements set forth in 326 IAC 5-1-2.

(9) Precarbonization emissions requirements shall be as follows:

(A) Particulate emissions from precarbonization towers shall be limited by the emission limitations contained in 326 IAC 6.8-2.

(B) Visible emissions from precarbonization towers shall comply with the requirements set forth in 326 IAC 5.
