REGULATORY COMPLIANCE THE CSCSD IS REGULATED BY: � The Regional Water Quality Control Board The State Water Resources Control Board � The State Porter-Cologne Act � The Federal Clean Water Act �
GOAL TO ELIMINATE SANITARY SEWER OVERFLOWS What is a Sanitary Sewer Overflow (SSO) or Sewage Overflow? � Raw Sewage Leaves the Pipe and Flows on the Ground Surface � Sewage, if Not Captured, Can Reach Storm Drains, Creeks, Lakes, the Bay, and Ocean � Recent 2-Hour Reporting Required (State OES, Regional Water Board, and County Environmental Health) SSO from Manhole Call (650) 363-4100 to Report Sewage Overflows
WHAT CAUSES SSO? Blockages, breaks, and Infiltration & Inflow (I&I) in the sewer pipe will cause SSO. Call (650) 363-4100 to Report Sewage Overflows
WHAT CAUSES SSO? Thin set mortar found to be the cause of SSOs in two other districts. Homeowners – be aware of private contractor’s work Call (650) 363-4100 to Report Sewage Overflows
WHY IS IT IMPORTANT TO ELIMINATE SSO? Untreated Sewage Affects Public Health, Animals, and the Environment.
EXAMPLES OF PUBLIC HEALTH ISSUES � City of Pacifica Wastewater Treatment Facility � 7.5 million gallons of partially treated sewage was spilled into the ocean in January 2008 � County closed all nearby beaches for five days � Sewerage Agency of Southern Marin Plant � 2.7 million gallons of sewage was spilled into the Richardson Bay in January 2008 � Oahu, Hawaii � 48 million gallons of sewage was spilled into the ocean in March 2006 Raw sewage contains harmful bacteria and viruses (fecal coliform, e-coli, etc.) that can cause diseases such as, hepatitis, giardiasis, and gastroenteritis. The EPA estimates that as many as 5,500 people get sick every year from direct exposure to sewer overflows near beaches
WHY IS IT IMPORTANT TO ELIMINATE SSO? To Avoid Costly Fines and Lawsuits! � Spills at sewage treatment plants and collection systems have received publicity � Agencies must report all SSOs to the State Water Board’s publicly accessible website � Recent spills at sewage treatment plants have forced changes in reporting requirements (Richardson Bay) – 2 hour reporting required � Cease and desist orders and lawsuits will define required system improvements and agency expenditures
Examples of Actions from Regional Water Board and Environmental Groups � The San Francisco Bay Regional Water Quality Control Board imposed a $516,000 fine to the City of South San Francisco in 2006 for sewer overflows � Baykeeper has filed a lawsuit against the City of Burlingame � The Regional Water Board is preparing a Cease and Desist Order for the all systems contributing to the City of San Mateo Sewage Treatment Plant
Wastewater Treatment Plant Upgrades and Collection System Work Are Affecting Many Agencies Estimated Capital Improvement Costs: � South Bayside System Authority – $335 Million � City of Burlingame – $20 Million � City of San Mateo – $34 Million
AGENDA Introductions � CSCSD Information � CSCSD Operations and Maintenance � Regulatory Compliance � Four Party Agreement � CSCSD Funding � Recommended Rate � Questions and Input �
FOUR PARTY AGREEMENT COVERS � Sewage Transport (Jointly Used Facilities) � Treatment and Disposal � Capital Improvement Projects on Jointly Used Facilities
WHO ARE THE FOUR PARTY AGENCIES?
WHAT DOES THE AGREEMENT SPECIFY? The Agreement entered into on July 18, 1989 specifies how costs are determined for each agency for their use of the “jointly used facilities”. � The costs include transport, treatment, disposal, operation and maintenance of “jointly used facilities”, and capital improvement projects on “jointly used facilities” � The CSCSD’s costs are calculated based on flow from the CSCSD
CSCSD FLOW METER CSCSD Meter Flow Comparison Between Dry and Wet Weather Conditions – Managing Wet Weather Flows Wet weather flow Dry weather flow
PROPOSED DOWNSTREAM AGENCY CAPITAL IMPROVEMENT PROJECTS The CSCSD, Hillsborough, and San Mateo are working together to develop timelines, cost estimates, and anticipated costs per agency for the following projects: � Town of Hillsborough • Crystal Springs-El Cerrito Trunk, Ph II or Detention � City of San Mateo • Working on Wet Weather Study • WWTP Expansion, Ph III • El Cerrito Relief Sewer Line • Force Main - Dale Ave to WWTP • WWTP Hydraulic Improvements I&I, SSO’s, and the impending cease and desist order will require downstream improvements. Total Estimated Cost = $42,600,000

CSCSD FUNDING CSCSD IS AN INDEPENDENT ENTITY WITH ITS OWN SEPARATE BUDGET � CSCSD receives sewer service charges and limited property taxes within the CSCSD boundaries to fund sewer service � The sewer service charges are a fee for service, not a tax � CSCSD collects sewer service charges on the tax bill because it is the least costly way to collect the fee
