BACKGROUND
Orange County Sanitation District (OC San) uses the OOBS and the Effluent Pump Station Annex (EPSA) to pump treated effluent from Plant No. 2 to the ocean through the outfall. In 2008, OC San completed construction of the EPSA Standby Power Facility which contains three 2-megawatt (MW) diesel generators connected to a paralleling 12.47kV switchgear.

There is an ongoing construction contract, J-117B, that is adding a fourth new 2MW diesel generator to the EPSA Standby Power Facility.
RELEVANT STANDARDS
