Philadelphia’s  CSO Nine Minimum Control # 6 & 7 Requirements   and  Implementation 

Philadelphia’s Consent Order and Agreement (COA) with the Pennsylvania Department of Environmental Resources (PaDEP) (link) paragraph K attaches the PaDEPs CSO Policy to the COA:


PaDEP’s CSO Policy, as documented in Appendix C of the COA (link),  requires Philadelphia’s “Continued Implementation of Technology-Based Nine Minimum Controls” (Attachment 1A, pg.13)
I have reproduced this section of the COA Attachment 1A for the readers convenience:
