New Requirements effective July 1, 2015

The State Water Board has adopted the proposed draft modified regulation for the California General Permit for Stormwater Discharges Associated with Industrial Activities.

All dischargers must to register for the new general permit electronically, on the “SMARTS” reporting system, and upload their Storm Water Pollution Prevention Plan and facility maps to the system by July 1, 2015.

This new permit requires that current Storm Water Pollution Prevention Plans and Monitoring Programs be updated to reflect the new requirements.

Some of the most noteworthy changes are:

  • All covered facilities will be required to register and submit documents to SMARTS to obtain coverage by the new General Permit, or to request non-exposure status.  Paper submittals will no longer be accepted.
  • Four rain events will be required to be sampled each year.
  • Qualifying rain events definition and sampling protocols have changed.
  • Mandatory BMP’s must be implemented for all, with additional mandatory BMP’s required for Plastics Facilities.
  • Additional BMPs will be required depending on facility specifics and feasibility.
  • Additional requirements for facilities that exceed instantaneous or averaged benchmark levels, including designating a Qualified Industrial Storm Water Practitioner (QISP), assessing current plan andimproving BMP’s at the site.
  • Facility employees are expected to be trained in the implementation of the SWPPP.  Training is required by a QISP for those facilities that exceed reporting action levels.
  • When facilities exceed sampling action levels, plans will be required to be evaluated and updated, and in some cases an action plan and technical report will be required.
  • No Exposure Certification – all covered industries must enroll in the program, and  can apply for a non exposure exclusion, if qualified.
  • Group Monitoring requirements have changed, including more frequent sampling by all group members.
  • There are opportunities to reduce sampling frequency.
  • Dischargers directly to ocean waters will require a specific Ocean Plan.

All facilities captured by the regulation are required to take action, including filing on SMARTS for coverage.

There are no longer exceptions for facilities that do not have materials exposed to stormwater.  All covered facilities must take action and register in SMARTS, either as a qualifying non exposure facility or as a facility meeting the full regulation.
