Alabama Administrative Code › Title 335 - ALABAMA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT › AIR DIVISION - AIR POLLUTION CONTROL PROGRAM › Chapter 335-3-4 - CONTROL OF PARTICULATE EMISSIONS › Section 335-3-4-.09 - Coke Ovens

Current through Register Vol. 42, No. 9, June 28, 2024
(1)
Applicability
. The provisions of this Rule shall apply
				to the production of coke in existing conventional slot-oven coke batteries
				with the exception of paragraph (10) of this Rule which applies to new
				batteries.
(2)
Unloading and Transfer of Coal and Coke
. Every person
				operating coke ovens shall apply all reasonable measures to prevent emissions
				from coal unloading, transfer, and coke transfer.
(3)
Charging
. There
				shall be no visible emissions during the charging cycle from the charging holes
				or the larry car of any battery with an opacity which is greater than twenty
				percent (20%) except for an average period or periods not to exceed three (3
				minutes of any consecutive sixty (60) minutes on batteries with less than
				seventy (70) ovens nor more than four (4) minutes of any consecutive sixty (60)
				minutes on batteries with seventy (70) ovens or more.
(4)
Pushing
.
(a) There shall be no visible emissions
				during the pushing cycle, other than water mist or vapor, with an opacity which
				is greater than forty percent (40%) for more than one (1) push per hour per
				battery.
(b) This paragraph
				specifically exempts existing conventional slot-oven coke batteries with forty
				(40) ovens located in Tuscaloosa County from subparagraph (a) above and imposes
				the following requirements:
1. There shall be
				no visible emissions during the pushing cycle, other than water mist or vapor,
				with an opacity which is greater than forty percent (40%) for more than two (2)
				pushes per hour per battery.
(c) Compliance with subparagraphs (a) and (b)
				of this paragraph shall be determined by dividing by four (4) the total number
				of pushes greater than forty percent (40%) opacity, observed during a four (4)
				hour observation period.
(d) Should
				the observation period include intervals of non-activity, (e.g., when the
				common coke car is servicing another battery) such intervals shall be included
				for purposes of determining compliance, provided that the average number of
				pushes per hour coincides with the average number of pushes per hour required
				by the normal production cycle of the battery. Intervals such as meal breaks,
				scheduled breaks when not on a twenty-four (24) hour pushing schedule, or
				intervals greater than fifteen (15) minutes due to malfunction of equipment
				cannot be included in the observation period.
(e) For purposes of this paragraph, "normal
				production cycle" shall mean the average number of pushes per hour determined
				by taking an arithmetic average of the pushing schedules of the previous ten
				(10) days. (The denominator to be based on the actual number of hours the
				pushing machine was scheduled to operate.)
(f)
Observation
				Procedures
.
1. The inspector
				shall evaluate the criteria listed below and select the most appropriate point
				at which to observe the visible emissions during the pushing cycle.
(i) The inspector should position himself as
				close to the source of pushing emissions as practical.
(ii) The inspector should observe pushing
				emissions against the sky.
(iii)
				The inspector should stand with the sun behind him, if possible, and with the
				emissions moving in any direction except directly toward or away from the
				inspector.
