Annual Reporting Requirements for Phase I MS4s
If you are a Phase I MS4 operator, your individual TPDES permit includes an annual reporting requirement. The reporting deadline is unique for each permit and is often based on the permit issuance date or the MS4’s fiscal year.
TCEQ staff will conduct administrative reviews of these reports using an annual report review form, and this review checklist will be mailed to each operator who submitted a report.
Phase I MS4 annual reports must be submitted to the following address AND to the appropriate TCEQ Regional office, unless otherwise specified in the individual permit:
Stormwater and Pretreatment Team Leader
TCEQ, Water Quality Division
P.O. Box 13087
Austin, Texas 78711-3087
The annual reports are no longer required to be submitted to the U.S. EPA because TCEQ is the permitting authority for medium and large MS4s.
Discharge Monitoring Reports for Phase I MS4s
Most TPDES Phase I permits require discharge data to be submitted on a Discharge Monitoring Report (DMR) form and submitted to the TCEQ in the annual report. TCEQ may not mail DMR forms to the permittees; however, the permittees may utilize a blank DMR form to tabulate the data. The reporting period for outfall monitoring may differ from the permit reporting year, so review your permit to determine what period the monitoring must cover.
DMR forms for Phase I MS4s must be submitted to the TCEQ within the required annual reports to the address specified above and to the appropriate TCEQ regional office.
EPA MS4 Permit Improvement Guide
On April 14, 2010, the U.S. EPA adopted the MS4 Permit Improvement Guide. The primary purpose of this guidance document is to assist permit writers at EPA and the states in strengthening Phase I and Phase II MS4 permits.
During the renewal of each individual Phase I permit, as well as during the Phase II general permit (TXR040000), the TCEQ intends to review this document to determine the extent to which the recommendations in this document will be incorporated into the TPDES MS4 permits.
Effect on Permit Requirements
Individual MS4 permits will be processed for renewal as they are received, with most applications expected to be submitted in late 2016 and 2017. The Phase I MS4 permit renewals will include additional minimum control measures from the Phase II regulations where appropriate. For specific questions on your permit conditions, please contact the Stormwater and Pretreatment Team.
