Caution: If your project is part of a larger common plan of
development, and the total number of acres disturbed under the
plan is 5 acres or more, then your project is not a small
construction activity. You must comply with the requirements for Construction Activities Disturbing 5
or More Acres.
When you disturb less than 5 acres (but at least 1 acre) of land
there are several ways to obtain authorization under the general
permit depending on the specifics of your construction
activity:
-
For a small construction activity you may follow the steps
necessary for coverage under the notice option.
-
If you disturb less than
1 acre of land, you do not need coverage under this general
permit to discharge storm water.
-
If construction is to take place in a particular county during a
particular time period when erosion is expected to be minimal (see
Appendix A of
TXR150000 {PDF}), you may be eligible for regulation under the
Low Potential for
Erosion Requirements (HTML). (Help with downloading files.)
-
If the potential for soil to wash away during your construction
activity is low, you may qualify for the Low Rainfall Erosivity
Waiver.
-
Even if you are eligible for coverage under a general permit,
you may opt to request coverage under an
individual permit.
-
If your activity is associated with the production or
exploration of oil and gas, your project may be under the
jurisdiction of the Texas
Railroad Commission
and
you may need authorization under the NPDES
program.
We encourage you to Contact
us if you have difficulty determining which method of
authorization best meets your particular circumstance.
