Storm Water Permitting Requirements for Medium and Large (Phase I ) MS4s

Explains the requirements and steps for applying for a permit to authorize storm water discharges from Phase I (medium and large) MS4s as well as annual reporting and discharge monitoring report requirements.

If you have an individual Phase I MS4 permit, then you must apply for a renewal permit from us at least 180 days before the existing permit expires.

Application Requirements

To renew coverage for your Phase I MS4:

  1. Complete the application formAdobe Acrobat PDF Document. (Help with PDF.) Be sure to prepare all attachments requested.

  2. Make sure the correct person signs the application form. See Title 30, Texas Administrative Code, Section 305.44Exit TCEQ for an explanation of who should sign the form.

  3. Submit the properly signed application form and all required attachments to our Storm Water Permitting Program.

  4. Submit the application fee of $2,005.00, plus $15.00 postage for renewals or $50.00 postage for major amendments:

    • Make the check or money order out to “TCEQ.”

    • To ensure proper credit, write “Phase I application fee” in the memo line of your check or money order.

    • Send your payment under separate cover to:

      TCEQ Revenues Section (MC-214)
      PO Box 13088
      Austin TX 78711-3088

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 formAdobe Acrobat PDF Document, 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:

Storm Water and Pretreatment Team Leader
TCEQ, Water Quality Division
MC-148
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 formAdobe Acrobat PDF Document 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 GuideAdobe Acrobat PDF Document. 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 2010 and 2011. While the specific recommendations have not yet been determined, it is likely that the Phase I MS4 permit renewals will include additional minimum control measures from the Phase II regulations where appropriate.
