EEC ENVIRONMENTAL Response to and Enforcement of Private Sewer Spills - A timely response to any SSO is critical not only in minimizing the environmental impact of the spill, but also in collecting/analyzing important information needed for reporting the spill and determining the cause(s) of the spill. EEC's SSO response experts are certified by the California Water Environment Association in SSO Electronic Reporting and are prepared to conduct follow-up investigations of private SSOs. Investigations consist of identification of the cause(s) of the SSO and discussions with agency staff to determine corrective actions. Preliminary discussions are conducted with property owners to implement corrective actions. EEC's extensive CCTV assessment of sewer lines provides clients with the necessary expertise to properly assess and offer recommendations concerning private sewer laterals. SSO Response Support Where "voluntary' implementation of corrective action by a property owner proves unsuccessful, administrative orders may be required to ensure implementation of required measures. Follow- up discussions with private property owners conducted by EEC are typically initiated well before the administrative order deadlines to ensure adequate progress and to avoid last-minute extensions. Sewer System Condition Assessment - EEC has analyzed countless hours of CCTV data and has used this data to drive capital improvement and sewer master plan development. EEC draws on this experience and expertise to ensure that an agency's planning and funding aligns with current asset conditions. Develop a sewer system maintenance (cleaning) program and schedule. - As discussed in the core services section, 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 Feld personnel, EEC deliverables will include cleaning program maps in formats compatible for use with the City's infraMAP software. The estimated level of effort for as -assigned general sewer system O&M support services is projected at approximately 200-250 hours.
