Stormwater Discharges from Construction Activities: Am I Regulated?
Construction General Permit (CGP)
Under the existing CGP TXR150000, issued March 5, 2013, construction activities from which runoff goes into or adjacent to any surface water in the state are regulated according to the area of land disturbed. (Help with PDF.)
Small construction activities which disturb at least 1 but less than 5 acres, or are part of a larger common plan of development that will disturb at least 1 but less than 5 acres, are also regulated under this general permit.
Construction activities that disturb less than 1 acre, and are not part of a larger common plan of development that would disturb 1 or more acres, are not required to obtain coverage under this general permit.
Oil and Gas Activities
The TPDES CGP does not authorize discharges from construction activities associated with the exploration, development, or production of oil or gas or geothermal resources, including construction associated with the transportation of crude oil or natural gas by pipeline. These discharges are not under the authority of the TCEQ. If coverage is required, operators of these construction activities may need to obtain permit coverage from the U.S. EPA and the Texas Railroad Commission.
