If you are a regulated small municipal separate storm sewer
system (MS4), you may be eligible for a waiver from the permitting
requirements if you meet ALL of the following criteria:
-
The MS4 serves a population under 10,000;
-
The TCEQ has evaluated all waters of the United States and has
determined that storm water controls are not needed for any pollutant of concern (PDF)
based on a total maximum daily
load (TMDL) or, if a TMDL has not been developed or approved,
an equivalent analysis that determines sources and allocations for
the pollutant of concern. (Help with PDF
Files.)
-
The TCEQ has determined that future discharges from the MS4 do
not have the potential to exceed Texas surface water quality
standards or cause other significant water quality impacts.
For the exact requirements of this waiver, refer to Title 40
Code of Federal Regulations, Section 123.35(d)(2)
.
Small MS4 operators may contact us to
learn how to request a waiver under this option. This waiver
requires a very comprehensive evaluation of all receiving water
bodies and may be difficult to obtain.
If you do not qualify for this waiver, you may be required to obtain
authorization.
