1. TPDES Permitting: Municipal Separate Storm Sewer Systems (MS4s) Updates Lower Rio Grande Valley 18 th Water Quality Management & Planning Conference May 18, 2016 Rebecca L. Villalba Texas Commission on Environmental Quality Stormwater & Pretreatment Team Water Quality Division (512) 239 4671

2. Quick Overview  Proposed Federal Phase II MS4 Remand Rule  Final Federal Electronic Reporting Rule  TxDOT Statewide Permit Update  Annual Reports

3. NPDES Phase II MS4 Remand Rule 40 CFR §§122.33 and 122.34  Proposed rule published in Fed. Reg. Jan. 6, 2016  Proposal includes three options for states to administer their Phase II MS4 programs Option 1: Traditional general permit approach Option 2: Procedural approach Option 3: State choice approach

4. NPDES Phase II MS4 Remand Rule Options  Option 1: Traditional general permit approach Prescriptive general permit  Option 2: Procedural approach Less prescriptive general permit MS4s develop a Stormwater Management Program (SWMP) States review the SWMPs – enforceable Only a couple of states have Option 2  Option 3: State choice approach  Choose Option 1 or 2, or a hybrid

5. NPDES Phase II MS4 Remand Rule Option 2 and Texas Approach  Texas Process Similar to Option 2 TCEQ develops a general permit with Minimum Control Measures (MCMs) General permit is not prescriptive, allows flexibility TCEQ publishes Public Notice in the newspaper and Texas Register Public can comment on the general permit – 30 day comment period Public Meeting held on the last day of the comment period

6. NPDES Phase II MS4 Remand Rule Option 2 and Texas Approach  Texas Process MS4 develops SWMP that addresses each MCM MS4 submits Notice of Intent (NOI) TCEQ conducts administrative and technical review of NOI TCEQ conducts technical review of the SWMP MS4 publishes Public Notice in the newspaper once the SWMP is technically complete 30 day comment period Opportunity for a Public Meeting

7. NPDES Phase II MS4 Remand Rule Option 2 and Texas Approach  Texas Process NOI and SWMP are approved and authorization issued SWMP is an enforceable document! Certain changes to SWMP need to be submitted to TCEQ for review and approval Notice of Change (NOC)

8. NPDES Phase II MS4 Remand Rule 40 CFR §§122.33 and 122.34  EPA states that the rule would not establish new requirements on MS4s  Comments on the rule were due March 21, 2016  TCEQ comments on the rule are available at: https://www.tceq.texas.gov/agency/nc/Water_Issues.html

9. NPDES Phase II MS4 Remand Rule 40 CFR §§122.33 and 122.34  Summary of TCEQ comments TCEQ supports Option 3 to provide greatest flexibility to states TCEQ also supports option 2 since it is most similar to TCEQ’s small MS4 program Changes to the NOI / SWMP after approval should not require public notice TCEQ does not support EPA reviewing NOI and SWMPs prior to TCEQ’s approval

10. Final EPA NPDES Electronic Reporting Rule

11.

16. TxDOT Statewide Individual MS4 Permit WQ0005011000  Structure of Permit Combined Phase I and Phase II MS4 permit requirements Requirements for discharges into impaired waterbodies similar to Phase II MS4 GP TXR040000 Provisions for enforcing the program as a non- traditional MS4 Develop a SWMP with five MCMs Level 2 MS4 provisions from Phase II MS4 GP TXR040000 Phase I MS4 provisions from TxDOT Phase I permits
