SWPPP General Requirements

• 
  

  1. The SWPPP shall be retained on site and made available upon request of a representative of the Regional Water Board and/or local storm water management agency (local agency) which receives the storm water discharges.

  2. The Regional Water Board and/or local agency may notify the facility operator when the SWPPP does not meet one or more of the minimum requirements of this Section. As requested by the Regional Water Board and/or local agency, the facility operator shall submit an SWPPP revision and implementation schedule that meets the minimum requirements of this section to the Regional Water Board and/or local agency that requested the SWPPP revisions. Within 14 days after implementing the required SWPPP revisions, the facility operator shall provide written certification to the Regional Water Board and/or local agency that the revisions have been implemented.

  3. The SWPPP shall be revised, as appropriate, and implemented prior to changes in industrial activities which:

     • may significantly increase the quantities of pollutants in storm water discharge
     • cause a new area of industrial activity at the facility to be exposed to storm water
     • or begin an industrial activity which would introduce a new pollutant source at the facility.

  4. The SWPPP shall be revised and implemented in a timely manner, but in no case more than 90 days after a facility operator determines that the SWPPP is in violation of any requirement(s).

  5. When any part of the SWPPP is infeasible to implement by the deadlines due to proposed significant structural changes, the facility operator shall submit a report to the Regional Water Board prior to the applicable deadline that

     • describes the portion of the SWPPP that is infeasible to implement by the deadline
     • provides justification for a time extension
     • provides a schedule for completing and implementing that portion of the SWPPP
     • and describes the BMPs that will be implemented in the interim period to reduce or prevent pollutants in storm water discharges and authorized non-storm water discharges.

     Such reports are subject to Regional Water Board approval and/or modifications. Facility operators shall provide written notification to the Regional Water Board within 14 days after the SWPPP revisions are implemented.

  6. The SWPPP shall be provided, upon request, to the Regional Water Board. The SWPPP is considered a report that shall be available to the public by the Regional Water Board under Section 308(b) of the Clean Water Act.
