CEEC ENVIRONMENTAL D. Update and provide training on the SSO contingency plans for the two City sewage lift stations. The risk of large SSOs is magnified in the event of sewage lift station failures. In collaboration with the City, EEC has developed an SSO contingency plan for the two lift stations and will continue to work with the City to update the plans and provide training for staff on specific plan procedures. E. Provide SSO response support, including data analysis, volume estimating, reporting, etc A timely response to any SSO is critical not only to minimize the environmental impact of the spill, but also to collect/analyze the information needed to determine the _ cause(s) of the spill. EEC currently supports the IRWD,... CMSD and the City of Santa Ana with follow-up investigations of private SSOs. Investigations consist of identification of the cause(s) of the SSO and discussions with agency staff to determine the required corrective actions. Preliminary discussions are conducted with property owners to implement corrective actions. EEC fully 550 Spill Simulation understands the importance of accurate volume estimations and timely reporting to CIWQS. EEC will continue to provide SSO response support and assist the City in training personnel on appropriate volume estimation methods and reporting forms. This core services task will be performed as an element of As -Assigned General Sewer System O&M Support services. F. Develop a sewer system maintenance (cleaning) program and schedule As part of the SSMP and the City's asset management endeavor, EEC will advance development of the sewer system maintenance and cleaning program and schedule. The program and schedule will prioritize sewer main cleaning based on parameters such as topography, pipe condition, flow characteristics, and historical inspection analyses. The sewer maintenance program is intended to optimize cleaning frequencies and resource deployment. EEC had previously developed and initiated pilot testing of this asset management practice with the City and is prepared to further test and implement the methodology system wide. Along with development and coordination with City field personnel, EEC deliverables will include cleaning program maps in formats compatible for use with the City's infraMAP software. This core services task will be performed as an element of As -Assigned General Sewer System O&M Support services. Value -Added WDR/SSMP Services EEC continues to serve local governments in developing, implementing, and monitoring sensible sewer system management programs tailored to address specific local conditions and ensure compliance with applicable WDR requirements. EEC has unmatched expertise in key SSO mitigation strategies, including FOG control programs, preparation of overflow ERPs, and SSMP performance assessments and audits. EEC continues to assist cities and independent special districts, including the Cities of Santa Ana, Stanton, La Habra, Buena Park, El Segundo, and Anaheim, as well as CMSD, with development, implementation, and/or audit of their SSMP strategies.
