I. Executive Summary

The Combined Sewer Overflow (CSO) Control Policy (CSO Policy) was issued in 1994 and incorporated into the Clean Water Act (CWA) in 2000. ⁽¹⁾ Since its issuance, communities with combined sewer systems nationwide have made substantial progress toward the goals established in the CSO Policy. During this same time, many factors that influence how communities address CSOs have evolved. Recognizing these ongoing changes and to aid communities addressing multiple municipal CWA requirements, in 2012, the EPA developed an Integrated Planning Framework that clarifies CWA flexibilities and offers a voluntary opportunity for a municipality to prioritize and sequence, where appropriate, those infrastructure projects that provide the greatest or fastest environmental and public health benefits. Integrated planning was added to the CWA in 2019. ⁽²⁾ The EPA is issuing this draft Guidance to clarify and inform future National Pollutant Discharge Elimination System (NPDES) permitting actions for communities with CSOs. This draft Guidance would be applicable to permitting actions once the CSO permittee has completed construction of CSO controls and demonstrated that they are achieving the performance objectives outlined in their Long-Term Control Plan (LTCP). The draft Guidance is intended to clarify the options available for CSO communities when they are nearing completion of the projects and activities identified in their LTCPs and inform future permitting actions consistent with the CSO Policy, and the CWA. In addition, the draft Guidance provides recommendations for permitting authorities on how to develop future CSO permits in more transparent, equitable, and resilient ways.

BILLING CODE 6560-50-P

⁽¹⁾  In the Wet Weather Water Quality Act of 2000, Congress added section 402(q) to the CWA to provide that each permit, order, or decree issued after December 21, 2000, for a discharge from a municipal combined storm and sanitary sewer shall conform to the 1994 Combined Sewer Overflow Control Policy (33 U.S.C. 1342(q)(1)).

⁽²⁾  In the Water Infrastructure Improvement Act (H.R. 7279), Congress added section 402(s) to the CWA that defines an Integrated Plan as one developed in accordance with the 2012 Integrated Municipal Stormwater and Wastewater Planning Approach Framework; and requires the EPA to inform municipalities of the opportunity to develop an Integrated Plan that may inform permit terms and conditions to help meet their existing CWA obligations (33 U.S.C. 1342(s)). These amendments clarified that municipalities may develop an Integrated Plan as defined under the CWA and the permitting authority may develop NPDES permit terms and conditions informed by that plan.
