Industrial Activities

The City of Stockton Stormwater Program works with local industries to prevent stormwater pollution through:

Industrial companies may require authorization under an NPDES industrial stormwater permit for stormwater discharges.


Industrial Stormwater Program

The Industrial Storm Water General Permit Order 97-03-DWQ (Construction General Permit) is an NPDES permit that regulates discharges associated with 10 broad categories of industrial activities.


The General Industrial Permit requires the implementation of management measures to achieve:

  • Performance standard of best available technology economically achievable (BAT)
  • Best conventional pollutant control technology (BCT)


The General Industrial Permit also requires:

  • development of SWPPP and monitoring plan to identify sources of pollutants and describe the means to manage the sources to reduce stormwater pollution and
  • an annual report submitted each July 1.

Facility operators may be able to participate in a group monitoring program.
