1. EPA Remand Rule for small MS4s Characterization of Current State Practices Nelly Smith Municipal Stormwater Coordinator Water Division US EPA Region 6

2. EDC v. EPA decision (Ninth Circuit, 2003) 1.Lack of permitting authority review:  “In order to receive the protection of a general permit, the operator of a small MS4 needs to do nothing more than decide for itself what reduction in discharges would be the maximum practical reduction.”  “No one will review that operator's decision to make sure that it was reasonable, or even good faith.” 2.Lack of public participation in permit process:  “… we conclude that … EPA’s failure to make NOIs available to the public or subject to public hearings contravene the express requirements of the Clean Water Act.”

3. NRDC/EDC petition to Ninth Circuit (2014)  Petitioners asked the Ninth Circuit to require EPA to take action to address the 2003 EDC v. EPA ruling  Petition requested the Court to order EPA to propose within 6 months (and finalize within 6 months after that date) a rule revising the Phase II small MS4 regulations to address the “procedural deficiencies” found in the Court’s 2003 order.  EPA and the petitioners signed a settlement agreement on Aug. 26 - On Sept. 14, the Ninth Circuit entered an order granting the joint motion and setting forth the following schedule to promulgate changes to the Phase II stormwater regulations  By Dec. 17, 2015, EPA shall sign for publication in the Fed. Reg. a notice of proposed rulemaking  By Nov. 17, 2016, EPA shall sign for publication in the Fed. Reg. a final rule

4. Proposed Rulemaking Options  Option 1 – “Traditional General Permit Approach”  Would clarify that each small MS4 permit must include all requirements necessary to meet the standard of “reducing pollutant discharges from the MS4 to the maximum extent practicable (MEP), to protect water quality, and to satisfy the appropriate water quality requirements of the CWA”  Option 2 – “Procedural Approach”  Retain the existing general permit framework that requires the MS4 to submit an NOI proposing specific actions to reduce discharges to the MEP  If considered adequate by the NPDES authority, establish a second permitting step that incorporates these specific actions as enforceable requirements of the general permit. This step would include public comment on proposed additional permit requirements and opportunity for public hearing, followed by permitting authority final action incorporating the additional permit requirements.  Option 3 – “State Choice Approach”  State is given the choice of how to establish permit requirements that meet the regulatory standard – the NPDES authority could achieve this exclusively through the permit (Option 1), by adopting a procedural mechanism to approve of individual MS4 programs (Option 2), or by using a hybrid of the two
