Industrial General Permit Order

General Permit, and (c) determine whether additional control measures are
needed.

56. This General Permit contains monitoring requirements that are necessary to
determine whether pollutants are being discharged, and whether response
actions are necessary. Data and information resulting from the monitoring will
assist in Dischargers’ evaluations of BMP effectiveness and compliance with
this General Permit. Visual observations are one form of monitoring. This
General Permit requires Dischargers to perform a variety of visual
observations designed to identify pollutants in industrial storm water
discharges and their sources. To comply with this General Permit
Dischargers shall: (1) electronically self-report any violations via SMARTS,
(2) comply with the Level 1 status and Level 2 status ERA requirements,
when applicable, and (3) adequately address and respond to any Regional
Water Board comments on the Discharger’s compliance reports.

57. Dischargers that meet the requirements of the No Exposure Certification
(NEC) Conditional Exclusion set forth in Section XVII of this General Permit
are exempt from the SWPPP requirements, sampling requirements, and
visual observation requirements in this General Permit.

K. Facilities Subject to Federal Storm Water Effluent Limitation Guidelines
(ELGs)

58. U.S. EPA regulations at 40 Code of Federal Regulations Chapter I
Subchapter N (Subchapter N) establish technology-based Effluent Limitation
Guidelines and New Source Performance Standards (ELGs) for industrial
storm water discharges from facilities in specific industrial categories. For
these facilities, compliance with the BAT/BCT and ELG requirements
constitutes compliance with technology-based requirements of this General
Permit.

59. 40 Code of Federal Regulations section 122.44(i)(3) and (4) require storm
water permits to require at least one Annual Evaluation and any monitoring
requirements for applicable ELGs in Subchapter N. This General Permit
requires Dischargers to comply with all applicable ELG requirements found in
Subchapter N.

L. Sampling and Analysis Reduction

60. This General Permit reduces the number of qualifying sampling events
required to be sampled each year when the Discharger demonstrates:
(1) consistent compliance with this General Permit,(2) consistent effluent
water quality sampling, and (3) analysis results that do not exceed numerical
action levels.

M. Role of Numeric Action Levels (NALs) and Exceedance Response Actions
(ERAs)
