PART II. COVERAGE UNDER THIS PERMIT

A. Authorization

This permit, including appendices, authorizes discharges of stormwater from a Large Municipal Separate Storm Sewer System as defined in 40 CFR § 122.26(b)(4) and described in the Permittee’s Stormwater Management Program in accordance with the requirements of this permit. This permit does not exempt or otherwise preclude the Permittee from complying with the requirements of Watershed Districts, Watershed Management Organizations, the County, or any other local, state, or federal rules and regulations.

B. Limitations on Coverage

  1. This permit does not authorize discharges other than stormwater. Non-stormwater discharges may include: combined sewer overflow, noncontact cooling water, sewage, wash water, scrubber water, spills, oil, hazardous substances, fill, commercial equipment and/or vehicle cleaning and maintenance wastewaters. A separate NPDES permit may be required for these discharges.
  2. This permit does not authorize the discharge of stormwater when a separate NPDES permit is required for these activities. For example, while stormwater from construction activity may be discharged from a municipal separate storm sewer system with authorized stormwater discharges, this permit does not replace or satisfy any other permits required for those discharges.
