body
BACKGROUND
The Orange County Sanitation District (Sanitation District) Laboratory Building at Plant No. 1 was constructed in 1991 and is essential for the operational monitoring and compliance verification for both wastewater treatment plants.
RELEVANT STANDARDS
* Sound engineering and accounting practices, complying with local, state, and federal laws
* Maintain a culture of improving efficiency to reduce the cost to provide the current service level or standard
PROBLEM
In April 2018, the four-natural gas-fired boilers for the Laboratory Building were tested by the South Coast Air Quality Management District (SCAQMD) and found not to be in compliance with nitrogen oxides emissions requirements. The four boilers were then shut down. The building is now heated from the plant's hot water loop, which is difficult to control and maintain a consistent temperature to avoid impacting laboratory analyses and causing occupant discomfort.
PROPOSED SOLUTION
Implement Plant No. 1 Laboratory Boiler Burner Replacement, Project No. MP-485, to replace the gas burners in the existing four boilers with new burners that meet the SCAQMD requirements.
TIMING CONCERNS
Until the new burners are installed and commissioned, the existing boilers will not be operational and consistent environmental heating to the laboratory building and its occ...
