EXECUTIVE SUMMARY
Approval of the Second Amendment to the contract with Larry Walker Associates, Inc. (LWA) will provide consulting services to assist the City with Municipal Separate Storm Sewer System (MS4) and Seaside Lagoon National Pollutant Discharge Elimination System (NPDES) Permits compliance and implementation in an amount not to exceed $200,000 per year for a total of $1,000,000 for a five-year term through June 30, 2027. The resulting contract total will amount to $2,206,000. LWA is currently assisting the City with numerous critical compliance activities associated with these permits; including submitting a renewed application for the Seaside Lagoon NPDES Permit and implementing the City’s Total Maximum Daily Load (TMDL) Non-Point Source Compliance program. The existing contract expires on June 30, 2022 so staff is requesting approval of the Second Amendment in order to allow continued, uninterrupted work on these, as well as other, critical matters.
BACKGROUND
In November 2012, the Los Angeles Regional Water Quality Control Board (Board) adopted the fourth MS4 NPDES Permit that identifies numerous conditions, requirements, and programs that municipalities must comply with in order to protect regional water resources from adverse impacts associated with pollutants in stormwater and urban runoff. The Permit requires cities to implement extensive and costly stormwater management and mitigation plans. In addition, the operation of the Seaside Lagoon is also regulated by a separate NPDES Permit that is enforced by the Board. The Lagoon’s existing NPDES Permit expires on October 31, 2022 and a Permit application for renewal is due to the Board by May 4, 2022. In order to renew the Permit, water quality studies and operational reports are required.
LWA is currently assisting staff in completing the permit renewal application that will include a proposed Time Schedule Order and a Waste Discharge Report. The studies and reports for this application will also inform the Board of the City’s future planned renovations to convert the Lagoon into a “closed-loop” system that would eliminate the need for an NPDES Permit. Approval of this Amendment will allow LWA to continue to assist with numerous technical tasks required to comply with the NPDES Permits, as well as provide various monitoring and sampling data management and assessment.
On September 1, 2015 the City Council awarded a contract in the amount of $490,000 to LWA to provide NPDES Permit compliance services following a competitive proposal process. The 2015 Request for Proposal consultant selection process identified LWA as the most qualified firm with excellent experience and references and they have successfully assisted the City with a multitude of tasks since the original contract was issued. On July 18, 2017 LWA was awarded the First Amendment in the amount of $716,000 to provide consulting services to assist with Municipal and Seaside Lagoon NPDES Permit compliance and implementation. In addition, a 2-year term was added to the Agreement, expiring on June 30, 2022.
Approval of the Second Amendment for consulting services will assist the City with implementation and compliance with the Seaside Lagoon and MS4 NPDES Permits, including the EWMP and CIMP programs. Some of the tasks to be performed by LWA include: prepare the various required Semi-Annual Reports, conduct various technical studies and monitor data management, implement the TMDL non-point source reviews and reports, conduct required staff training, enter monthly and extensive water quality data into the Board’s compliance database, coordinate required water quality sampling with the City’s contract laboratory, update programs and policies associated with major MS4 Permit minimum control measures, perform staff training, develope public information documents, assist with potential Seaside Lagoon water quality compliance issues (limitation exceedance investigations, analysis, and report preparation), and prepare data summary tables with accompanying narrative to be included in the effectiveness assessment of the MS4 annual reports.
COORDINATION
The City Attorney’s Office prepared and approved the Second Amendment with LWA.
FISCAL IMPACT
Funding for this work is available in the approved Public Works Department annual maintenance and operations budget. The work authorized each year will be limited to an amount not to exceed $200,000 with a revised total contract value not to exceed $2,206,000 over the life of the contract through June 30, 2026.
