8.03 Texas Construction General Permit (CGP)
Construction activities that discharge storm water runoff into or adjacent to any surface water of
the state are regulated by the state of Texas under the Construction General Permit (CGP)
(TXR150000). The governing agency is the Texas Commission on Environmental Quality
(TCEQ). Construction activities are regulated according to the area of land disturbed.
Large construction activities
For sites that disturb five or more acres, or are part of a larger common plan of development that
will disturb five or more acres, and meet the definition of an operator, the following applies:
• Prepare and implement a Storm Water Pollution Prevention Plan (SW3P)
• Post a Site Notice
• Submit a copy of the Site Notice to the MS4 Operator
For sites that disturb five or more acres, and meet the definition of a primary operator, the
following applies:
• Prepare and implement a SW3P
• Submit a Notice of Intent (NOI) to TCEQ
• Post the NOI and Site Notice
• Submit a copy of the NOI to MS4 Operator
Small construction activities
For sites that disturb at least one but less than five acres, or are part of a larger common plan of
development that will disturb at least one, but less than five acres and meet the definition of an
operator, the following applies:
• Prepare and implement a SW3P
• Post a Site Notice
• Submit a copy of the Site Notice to the MS4 Operator
Sites that disturb less than one acre and that are not part of a larger common plan of development
that would disturb one or more acres, are not required to have coverage under the general permit.
Refer to the General Permit definitions for Operator and Primary Operator. Additional

8.04 Storm Water Pollution Prevention Plan (SW3P)
One of the requirements of the Construction General Permit is to develop an SW3P. The purpose
of the SW3P is to provide guidelines for minimizing sediment and other pollutants that may
originate on the site, from flowing into municipal storm systems, or jurisdictional waters during
construction. The plan must also address the principal activities known to disturb significant
amounts of ground surface during construction.
