2. Minimum and Advanced BMPs

Section V of this General Permit requires the Discharger to comply with
technology-based effluent limitations (TBELs). In this General Permit,
TBELs rely on implementation of BMPs for Dischargers to reduce and
prevent pollutants in their discharge. The BMP effluent limitations have
been integrated into the Section X.H of this General Permit and are divided
into two categories – minimum BMPs which are generally non-structural
BMPs that all Dischargers must implement to the extent feasible, and
advanced BMPs which are generally structural BMPs that must be
implemented if the minimum BMPs are inadequate to achieve compliance
with the TBELs. Section X of this General Permit includes both substantive
control requirements in the form of the BMPs listed in Section X.H, as well
as various reporting and recordkeeping requirements. The requirement to
implement BMPs “to the extent feasible” allows Dischargers flexibility when
implementing BMPs, by not requiring the implementation of BMPs that are
not technologically available and economically practicable and achievable
in light of best industry practices.
