960.20  STORM WATER PERMIT COVERAGE.
   (a)   The permit covers all requirements for new and existing discharges, composed entirely of storm water and associated with earth-disturbing activity that enter Waters of the State or a storm drain leading to Waters of the State. The permit controls earth-disturbing activity, soil storage, and erosion and sedimentation resulting from earth-disturbing activities and establishes procedures for issuance, approval, administration, and enforcement of the permit.
   (b)   Support Activities. The permit authorizes storm water discharges from support activities, including but not limited to, equipment staging yards, material storage areas and excavated material areas provided:
      (1)   The support activity is directly related to a construction site that is required to have coverage by the permit for discharges of storm water associated with construction activity;
      (2)   The support activity is not a commercial operation serving multiple unrelated construction projects and does not operate beyond the completion of the earth-disturbing activity at the site it supports;
      (3)   Appropriate controls and measures are identified in the SWP3, if applicable, covering the discharges from the support activity; and
      (4)   The support activity is on or contiguous with the property defined in the application and the SWP3, if applicable.
   (c)   Limitations on Coverage. The following storm water discharges associated with construction activity are not covered by the permit:
      (1)   Storm water discharges that originate from the site after earth-disturbing activities have been completed, including any temporary support activity, and the site has achieved final stabilization;
      (2)   Storm water discharges associated with construction activity that the City Engineer has shown to be or may reasonably expect to be contributing to a violation of a water quality standard; and
      (3)   Spills and releases in excess of reportable quantities.
         A.   In the event of a spill or other unintended release, hazardous substances in the storm water discharge from a construction site must be minimized in accordance with the applicable SWP3 for the construction activity; and
         B.   In no case may the discharge(s) contain a hazardous substance equal to or in excess of reportable quantities.
   (d)   The permittee shall inform all contractors and subcontractors who will be involved in the implementation of any or all parts of the permit of the terms and conditions of the permit and the associated SWP3.
      (1)   The permittee shall maintain a written document containing the signatures of all the contractors and subcontractors as proof acknowledging that they reviewed and understand the conditions and responsibilities of the permit and, if applicable, the associated SWP3.
      (2)   The written document shall be created and signatures shall be obtained prior to commencement of earth-disturbing activity on the construction site.
   (e)   It is the duty of the permittee to notify the City Engineer forty-eight hours prior to commencement of earth-disturbing activities and upon project completion for all development with an approved permit.
