Compliance Schedule

Upon receipt of the Notice of Intent letter, the MS4 entity is required to begin to implement the program based on a compliance schedule The time tables referenced below and in the 327 IAC 15-13 (Rule 13), Rule Language (Scroll to the bottom of Page 68) become effective on the date that the NOI letter is received by IDEM. From this receipt date, the compliance schedule begins, and the time tables for required program submittals begin. As an example, the SWQMP-Part B: Baseline Characterization and Report is due 180 days from receipt of the NOI letter

If an MS4 operator is unable to meet a compliance deadline as identified in the Rule, the MS4 Operator is required to submit a written request and justification for extending the deadline. The request must be submitted to IDEM no later than thirty (30) days prior to the due date. The request should be sent to the attention of the MS4 Coordinator.

An MS4 operator shall comply with the following schedule for implementation of this rule:

1 The compliance schedule, and the appropriate rule sections related to each specific Minimum Control Measure (MCM), depict the timetable for development and implementation of each required ordinance or similar regulatory mechanism. All ordinances or similar regulatory mechanisms, except for the one related to the post-construction MCM, must be developed and implemented no later than one (1) year from the submission of the NOI letter. The post-construction MCM allows for development and implementation within two (2) years. The intent of the post-construction MCM extension is to allow MS4 operators more time, by developing a SWQMP-“Part C” first, and, based on the implementation plan, to determine appropriate best management practices that will be implemented within the MS4 area.
