Order Conditions |
Did not comply with wet weather plant operational requirements, as described in Provision VI.C.5.c.iv. INF flow was not maximized due to a power outage at the Westside Pump Station, which stopped all pumping to OSP. Per the February SMR cover letter, CSDs from Vicente and Lincoln occurred on 2/4 at 7:15 p.m. and 7:40 p.m., respectively. It is not possible to determine whether CSDs would have occurred if there hadn?t been a power loss. |

Because the BOD sample results were above the permitted effluent limits, but not representative of the effluent (as described below), Regional Board staff determined that the samples were not in compliance with Attachment D, section III.A of R2-2013-0029. |

Deficient Monitoring |
SFPUC invalidated three samples (9/23/2023, 9/24/2023, 9/25/2023) with high BOD results due to algae found in the composite sample. Because the BOD sample results were above the permitted effluent limits, but not representative of the effluent (as described below), Regional Board staff determined that the samples were not in compliance with Attachment D, section III.A of R2-2013-0029. |
