body
BACKGROUND
The Orange County Sanitation District (OC San) operates three clean-burn internal combustion engines that generate electricity at the Plant No. 1 Central Generation (Cen Gen) facility. Cen Gen also provides process heat to the digester complex at Plant No. 1. They also use methane-rich digester gas produced during wastewater treatment, reducing emissions and supporting compliance with South Coast Air Quality Management District permit requirements.
CenGen engine components must meet original equipment manufacturer (OEM) specifications to maintain performance, efficiency, and emissions compliance. Air intake manifolds are critical engine components that distribute combustion air to the cylinders. A damaged or failed manifold can disrupt airflow, cause uneven combustion, increase emissions, and result in an engine shutdown. Maintaining spare manifolds is necessary to support reliable CenGen operation.
RELEVANT STANDARDS
Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting
24/7/365 treatment plant reliability
Maintain a proactive asset management program
