Industrial General Permit Fact Sheet
Regional Water Board staff, with the assistance of State Water Board staff, will develop
and submit the proposed TMDL-specific permit requirements for each of the TMDLs
listed in Attachment E by July 1, 2016.5 After conducting a 30-day public comment
period, the Regional Water Boards will propose TMDL-specific permit requirements to
the State Water Board for adoption into this General Permit. The Regional Water
Boards may also include TMDL-specific monitoring requirements for inclusion in this
General Permit, or may issue Regional Water Board orders pursuant to Water Code
section 13383 requiring TMDL-specific monitoring. The Regional Water Boards or their
Executive Officers may complete these tasks, and the proposed TMDL-specific permit
requirements shall have no force or effect until adopted, with or without modification, by
the State Water Board. Unless directed to do so by the Regional Water Board,
Dischargers are not required to take any additional actions to comply with the TMDLs
listed in Attachment E until the State Water Board reopens this General Permit and
includes TMDL-specific permit requirements. This approach is consistent with the 2008
MSGP. TMDL-specific permit requirements are not limited by the BAT/BCT technology-
based standards.
The Regional Water Boards will submit to the State Water Board the following
information for each of the TMDLs listed in Attachment E:
Proposed TMDL-specific permit requirements, including any applicable effluent
limitations, implementation timelines, additional monitoring requirements,
reporting requirements, an explanation of how an exceedance of an effluent
limitation or a violation of the TMDL will be determined, and required deliverables
consistent with the TMDL(s);
An explanation of how the proposed TMDL-specific permit requirements,
timelines, and deliverables are consistent with the assumptions and requirements
of applicable waste load allocation(s) to implement the TMDL(s);
Where a BMP-based approach is proposed, an explanation of how the proposed
BMPs will be sufficient to implement applicable waste load allocations; and
Where concentration-based monitoring is required, an explanation of how the
required monitoring, reporting and calculation methodology for an exceedance of
an effluent limitation or a violation of the TMDL(s) will be sufficient to
demonstrate compliance with the TMDL(s).
Upon receipt of the information described above, the State Water Board will conduct a
public comment period and reopen this General Permit to populate Attachment E, the
Fact Sheet, and other provisions as necessary in order to incorporate these TMDL-
specific permit requirements into this General Permit. Attachment E may also be
reopened during the term of this General Permit to add additional TMDLs and
corresponding implementation requirements.
This General Permit (Section X.G.2.a.ix) requires a Discharger to identify any additional
industrial parameters that may be discharged to a waterbody with a 303(d) impairment
identified in Appendix 3 as likely to be associated with industrial storm water.
5 Due to the workload associated with the implementation of this General Permit (e.g., training program development, NEC
outreach, electronic enrollment and reporting via SMARTS) it is believed that two years in necessary for Staff to complete a
comprehensive analysis and stakeholder process for TMDLS applicable to Dischargers under this General Permit.
