If you operate a regulated small municipal separate storm sewer
system (MS4), you might be eligible for a waiver from the
permitting requirements under TPDES Permit Number TXR040000 if your MS4 meets every one of
these conditions:
-
The MS4 serves a population of less than 1,000 within an
urbanized area.
-
The MS4 does not contribute substantially to the pollutant
loadings of a regulated, physically interconnected MS4 (small,
medium, or large).
-
If the MS4 discharges any pollutant that has been identified as a cause of
impairment (PDF) to any water body to which the MS4 discharges,
storm water controls are not needed based on the waste load
allocation that is part of an EPA-approved or established "total maximum daily
load" (TMDL) for that pollutant. (Help with PDF
Files.)
If you are eligible for a waiver, then you must complete and
submit a waiver certification form.
For the exact requirements of this waiver, see the general
permit, TXR040000, or the federal rules related to waivers at Title
40, Code of Federal Regulations, Section
123.35(d)(1)
.
If an MS4 meets each of these conditions, then the MS4 operator
may request this waiver by submitting a waiver certification form to the
TCEQ.
