Updates to NPDES eRule Data Elements To Reflect MS4 General Permit Remand Rule (Final)
Apr. 15, 2020
EPA is updating specific data elements within the NPDES eRule, published on 22 October 2015, that apply to regulated MS4s. These changes are necessary given the promulgation of a separate rulemaking after publication of the NPDES eRule that modified the NPDES permit requirements for small MS4s. That rule, referred to as the MS4 General Permit Remand Rule, published on 9 December 2016, made a number of the MS4-related data elements in the NPDES eRule no longer accurate. This final rule updates those data elements to be consistent with the current MS4 regulations, corrects related typographical errors, and makes other selected clarifications at the request of state NPDES permitting programs. This final rule is effective on 15 May 2020.
