The ELG compliance date has been delayed due to the latest update to the 40 CFR 423. EPA made changes to the earliest implementation date and the Allen permit is being updated accordingly. The new earliest implementation date is 11/01/2020. The anti -backsliding provision of the CWA does not apply in this case since the compliance date in the permit has not been reached yet. 2) The DEQ Must Eliminate Any Ambiguity Over Internal Outfall 005. This is a Major Modification of the permit, not the permit renewal. When the Major Modification is processed, only a portion of the permit is being reopened. The rest of the permit remains intact until the next renewal. Each permitted facility undergoes numerous changes during the term of the permit and if the permit allows for this change to occur, there is no need to make the permit change until the renewal. Otherwise the DEQ would be forced to constantly update every permit. The permit already allows the discharge of the FGD wastewater to the Retention Basin. In addition, it is useful to preserve the option to discharge FGD wastewater to the Ash Basin in case of the unforeseen circumstances. Page 1 of 1
