Strengthening the protective elements of your permit

TCEQ continued utilizing the U.S. EPA MS4 Permit Improvement Guide Adobe Acrobat PDF Document (adopted April 14, 2010) as during the 2013 permit renewal process. In addition, TCEQ incorporated the requirements of the federal MS4 Remand Rule from January 9, 2017, in the general permit and used the following guidance documents: Compendium of MS4 Permitting Approaches - Part 2: Post Construction Standards (EPA, 2016); Compendium of MS4 Permitting Approaches – Part 3: Water Quality-Based Requirements (EPA, 2016).

Annual Reports

All existing regulated MS4 entities are required to submit annual reports covering each year of the general permit's term.

The deadline or the reporting month for submitting annual reports for the general permit is based on the reporting period selected in the NOI submitted to TCEQ to obtain permit coverage.
