b. If these requirements are not met, then stipulated penalties will be triggered.
c. If the Oven Wall Study Work Plan demonstrates that refractory replacement at a battery is necessary, and a good faith engineering estimate is at least $15,000,000, the facility may submit to the Department a new deadline to meet the requirements and obtain the compliance certification.
3. Continuing Obligations for Batteries 1, 2, and 3
a. Soaking emissions are defined as uncombusted emissions from an open standpipe which has been dampered off in preparation of pushing the coke mass out of the oven, and end when pushing begins when the coke side door is removed.
b. At no time may the soaking emissions from the standpipe cap opening exceed 20% capacity. An exclusion from this opacity limit is allowed for two minutes after the standpipe is opened.
c. The coking time shall not be less than 21.75 hours, for each of the three batteries. The facility is required to submit to the Department information on deviations from this requirement, on a quarterly basis. Coking times less than this time period are considered to be in compliance if they are caused by or are related to a Start-Up, Shutdown, Breakdown, or Malfunction, or if they are caused by extraordinary circumstances.

a. The facility must operate the baffle wash system of B Quench Tower during the quenching of coke, as long as the ambient temperature is above 32 degrees Fahrenheit.
b. The facility must certify compliance with charging standards or provide an updated Compliance Schedule, by April 30, 2016.
Civil Penalty
The Consent Judgment only imposed an additional civil penalty of $25,000.
While the document memorializes a civil penalty of $3,973,000 in full settlement of all issues and alleged violations, $3,948,000 was already paid in civil penalties under 2008, 2011, 2014 consent orders, and various statements of violation. See Consent Judgment at par. 23, Section VII(A).
Stipulated Penalty
If the facility does not meet or maintain compliance with the compliance certification requirements for any battery, it must pay a stipulated penalty of $20,000 per battery per month. Starting on the thirteenth month of noncompliance, the stipulated penalty rises to $40,000 per battery per month.
Additionally, there is a stipulated penalty of $500 for each clock hour that compliance for the Batteries’ combustion stacks is not achieved for opacity limits. section 2105.21(f)(3) and (f)(4). But the first 33 clock hour opacity limit violations of each battery stack in any calendar quarter shall not be subject to stipulated civil penalties.
