AYES: Supervisors Rogers, Smith, DeSaulnier, Torlakson, Bishop
NOES: None
ABSENT: None
ABSTAIN: None RESOLUTION NO. 95/251
SUBJECT: A RESOLUTION TO APPROVE A PROJECT FOR THE DISCOVERY BAY
WASTEWATER TREATMENT FACILITY WHICH WILL REPLACE
EXISTING CHLORINE/SULFUR DIOXIDE DISINFECTION SYSTEM WITH
ULTRAVIOLET LIGHT DISINFECTION, SANITATION DISTRICT NO. 19,
DISCOVERY BAY AREA.
The Board of Supervisors of Contra Costa County RESOLVES THAT;
WHEREAS, the Discovery Bay Wastewater Treatment Facility discharges treated wastewater
under an National Pollutant Discharge Elimination System (NPDES) permit, which is based on
the Clean Water Act and the California Water Code, and requires effluent disinfection to meet an
established total coliform limit; and
WHEREAS, the Discovery Bay Wastewater Treatment Facility stores and handles two acutely
hazardous materials, chlorine and sulfur dioxide to disinfect treated wastewater; and
WHEREAS, recent programs and regulations to protect public and workers safety, such as the
Risk Management and Prevention Program and the Community Warning System, have made the
continued use of these chemicals more costly, and
WHEREAS, and engineering study has shown that replacing the chemical disinfection system with
and ultraviolet light (UV) disinfection system is cost effective and virtually eliminates all safety
hazards and regulatory issues; and
WHEREAS, UV disinfection is a non-chemical method of pathogen destruction, and exposes
wastewater to electromagnetic energy (UV light) to prevent the cellular proteins and nucleic acids
(DNA and RNA) in pathogens from further reproduction; and
WHEREAS, it has been shown that UV disinfection is an effective disinfection method, and is
both environmentally friendly and safe.
NOW, THEREFORE, BE IT RESOLVED by this Board, as Ex Officio Governing Board of
Contra Costa County Sanitation District No. 19, that:
1. Replacement of the existing chemical disinfection system at the Discovery Bay
Wastewater Treatment Facility with a UV disinfection system is the best project
from economic, risk management and liability perspective, and
2. Funds from Sanitation District 19, Byron Operating Fund No. 239300 will be used
to finance the project, and
3. Sanitation District 19 funding of the State Risk Management and Prevention
Program, ,the Process Safety Management Program (OSHA), the Federal Risk
Management Program, and the Community Warning System should diminish due
to the eminent removal of acutely hazardous materials from the facility site once
the UV system has been in operation for a while.
