2. Visual Observations
There are two major changes to the visual observation requirements in this General
Permit compared to the previous permit, which include:
a. Monthly Visual Observations
The previous permit required separate quarterly visual observations for
unauthorized and authorized non-storm water discharges. It did not require
periodic visual observations of the facility to determine whether all potential
pollutant sources were being adequately controlled with BMPs. Prior drafts of
this General Permit proposed the addition of pre-storm inspections. This was
met with great resistance by Dischargers because of the complexity and burden
of determining when a QSE would occur. Many of these Dischargers
recommended that monthly BMP and non-storm water discharge visual
observations should replace the proposed pre-storm inspections. This General
Permit merges all visual observations into a single monthly visual observation.
b. Sampling Event Visual Observations
