General Aspects Project Sponsor Profile

5. City of Calipatria Rapid Assessment Process Project Strategic Plan General Aspects  Existing  Distribution system is owned and operated by the Southern California Water Company;  Water obtained from Imperial Irrigation District;  Non-metered service; Customers pay a flat rate of $41.78 / month Existing Water Treatment, Storage, & Distribution System  Concerns  System pressure was increased to serve the prison and resulted in line breaks;  Difficulty determining illegal connections due to non-metered service;  Public perception is unfavorable with a general distrust for rate increases and lack of service.  Current Improvements  Water Treatment Plant Expansion to satisfy Enhance surface Water Quality Rule;  Construction of transmission main to Niland to service both communities.. Water system privately owned and is ineligible for grant funding to develop improvements.

6. City of Calipatria Rapid Assessment Process Project Strategic Plan General Aspects  Collection  Existing system consists of 92,000 linear feet vitrified clay and PVC pipe;  Approximately 99.9% of population served (850 service connections);  Lift Station  One lift station with wet well/dry well configuration;  CAL Prison maintains lift station and bar screen with dedicated sewer main to Calipatria WWTP; Condition is undetermined but no problems reported.  Treatment  The City of Calipatria has an aeration pond system;  Average design flow 1.70 MGD;  Currently operating at 0.85 MGD 60-70%;  Designed to treat domestic wastewater;  Expanded in 1990 to accommodate CAL Prison. Existing Wastewater Collection and Treatment System

7. City of Calipatria Rapid Assessment Process Project Strategic Plan General Aspects  Collection  Sewer mains constructed over fifty years ago;  Numerous line breaks within past eighteen months;  Existing manholes require repair and/or replacement;  Groundwater infiltration into collection system is suspected due to elevated levels of pollutants at the WWTP.  Lift Station  No emergency provisions;  Power interruption results in surcharge at residences;  Lack of ventilation creates potentially hazardous environment.  Treatment  Absence of screening results in blockage throughout plant;  Elevated levels of cyanide, selenium and thallium with source unknown;  E. Coli detected in plant effluent;  Overflow at ponds observed; Minimal maintenance has possibly decreased the pond capacity and liner condition is undetermined;  Numerous violations issued for BOD 5 and E. Coli;  Prison flow quantity and composition is unverified, screening is inadequate with typically higher solids (trash, etc); current contract does not have any provisions for safeguards. Wastewater System Deficiencies

8. City of Calipatria Rapid Assessment Process Project Strategic Plan General Aspects Evaluation and inspection of the existing system will assist in selecting and implementing the necessary improvement to include the following possible alternatives:  Collection  Rehabilitation/Replacement of existing system;  Install clean-outs at the dead ends.  Lift Station  Construction of a new lift station or rehabilitation of the existing with sufficient redundancy;  Provide stand-by power.  CAL Prison lift station to install new screening; consider renegotiating the contract with the prison.  Treatment  Construct testing laboratory as appropriate for process control;  Screen influent and provide additional mixing aerators;  Clean ponds and improve water transfer between ponds;  Provide stand-by power;  Reuse of treated effluent. Proposed Wastewater System Improvements Total Estimated Cost - $TBD

12. City of Calipatria Rapid Assessment Process Project Strategic Plan Environmental and Human Health Indicators Environmental Indicators  Levels of E. Coli, violating state regulations have been observed in effluent and may pose potential health risk downstream of discharge  Existing plant not designed to treat cyanide, selenium and thallium at the WWTP and discharge within the effluent may be occurring;  Lack of maintenance at plant may have reduced capacity thus reducing efficiency and worsening conditions above;  Numerous lines breaks and manhole leaks have created nuisance condition throughout Calipatria;  Potential groundwater contamination may affect environmentally sensitive areas including farmland, habitats for protected species and water bodies including the Salton Sea.  Elevated Levels of BOD 5

13. City of Calipatria Rapid Assessment Process Project Strategic Plan Environmental and Human Health Indicators Compliance with Environmental Norms & Regulations  Water System  Metering required;  Improve THM and turbidity levels  Wastewater System  Administrative Civil Liability Complaint issued by California Regional Water Quality Control Board for numerous violations;  Majority of violations related to BOD 5 in effluent; Also E.Coli detections;  Calipatria agreed to complete compliance projects as an alternative to paying the assessed fines;  Under the CP program Calipatria is obligated to spend an equivalent amount toward approved improvements.

14. City of Calipatria Rapid Assessment Process Project Strategic Plan Environmental and Human Health Strategies  Present an acceptable Compliance Project to Water Control Board.  Determine the CEQA/NEPA document requirements, an EIS or EA.  Analyze the chemical composition of the wastewater and groundwater to determine the nature and possible source of contaminants existing at the WWTP.  Conduct an analysis of the WWTP influent to detemine the sufficiency of oxygen as it is introduced in the treatment process.  Verify the quantity and existing chemical make-up of the prison contributions and the existing screening methods to eliminate potential source of pollutants. Establish a pretreatment program and renegotiate the contract with CAL Prison.  Describe the environmental and human health risks associated with the deteriorated conditions of the existing collection system infrastructure as well as with the WWTP and effluent violations and develop a comprehensive O&M Program

15. City of Calipatria Rapid Assessment Process Project Strategic Plan Sustainable Development Strategies  Two stakeholder workshops to be conducted. The baseline conditions report is complete.  Demonstrate appropriate institutional capacities:  Establish permanent operation staffing Regional Operations – Shared operators with Niland Sanitary District/other.  Seek Training NADB UMI; Operator and administrative development  An operation and maintenance program will be developed as part of the project.  Coordinate with water provider to develop a water usage assessment, including possibilities for conservation/reuse.  Determine if there is a need for industrial pretreatment.  30% design review by system operator
