If your construction project disturbs less than 1 acre and is
not part of a larger common plan of
development (HTML), coverage under General Permit (TXR150000) (PDF) is
not required. (Help with PDF.)
If your project is part of a larger plan, the total number of
acres disturbed under that larger plan must be considered when
determining how this general permit (TXR150000) (PDF)
applies to you:
Example 1. A subdivision is being built. You
are grading 0.75 acres, another company is clearing 4 different
acres, and a contractor is excavating another 0.5 acres. Because
the total area that would be disturbed under this
common plan is 5.25 acres, each operator would fall under the
requirements associated with disturbing 5
or more acres (HTML).
Example 2. At first, your project calls for you
to grade, clear, or excavate a total of 0.93 acre. But after your
project begins, you learn that you must disturb another 0.15
acre—perhaps to add more parking and an access road. Because
this project has grown to disturb a total of 1.08 acres, you must
obtain coverage under the requirements for disturbing 1
to less than 5 Acres (HTML).
