EEC Environmental (EEC) has a demonstrated understanding of the SSO waste discharge requirements (WDR), from its 2002 inception to its current form. Since 2003, extensive experience providing fats, oils, and grease (FOG) control program and WDR services and complementary services have gained EEC an excellent reputation and working relationship with federal, state, and local agencies.
Since 2005, EEC has worked with a Southern California Sanitary District (District) to manage their WDR related projects including SSO reduction. These services have included conducting sewer system characterization to identify and mitigate enhanced maintenance locations (EMLs). Causes of the EMLs are identified through the use of closed-circuit television (CCTV) inspections and the necessary actions to eliminate the EML are identified. EEC meets with District staff quarterly to review these locations and develop the necessary action plans. EEC tracks the progress of EML related activities on an Excel spreadsheet and maintenance activities related to EMLs is tracked on the District’s City Works database.
Additionally, EEC conducted the internal SSMP Audit for the District which included an in-depth review of SSMP related documents, interviews with District staff, and an in-depth report of the findings and recommended corrective actions. Documents reviewed included the SSMP, SSO Emergency Response Plan, Master Plan, Sewer System O&M Manuals, and FOG Control Program Documents.
Finally, EEC assists the District with the response to private SSOs and conducts follow-up inspections at food service establishments when the cause of the SSO is grease related. EEC also assists with determining enforcement actions for the property owner responsible for the SSO including drafting enforcement letters.
