Overview
•What is the UPDES program and how
does the permitting process work
•JVWCD’s UPDES permit application
•Upcoming information session and public
comment period
Authority
•EPA is authorized under the CWA to
implement the National Pollutant
Discharge Elimination System Program.
•EPA has delegated authority to Utah to
administer the NPDES Program.
Beneficial Use Designations
(Classifications)
•Class 5A Gilbert Bay Segment of GSL
•Beneficial Uses –Protected for infrequent
primary and secondary contact recreation,
waterfowl, shore birds and other water-
oriented wildlife including their necessary
food chain.
Water Quality Standards
•Water Quality Standard -the
maximum amount of pollutant a
waterbody can carry and still
maintain its beneficial uses.
GSL Water Quality Standards
•Selenium Tissue Standard
•Narrative Standard
–R317-2-7.2
In other words…
Under the Clean Water Act and the Utah
Water Quality Act, the DWQ can allow
pollution of waters of the State up to a
certain point (the WQ standard) as long as
the beneficial use is maintained.
Utah Pollution Discharge
Elimination System
The goal of the UPDES program is to
protect surface water quality by
regulating discharge of pollutants to
waters of the State.
Protects the beneficial use of a
receiving water by limiting
concentrations and types of
pollutants in a discharge.
