MWD Rialto Pipeline Treatment Plan for Golden Mussel Mitigation

The Department of Water Resources (DWR) is implementing a targeted chemical treatment plan to prevent the settlement and establishment of golden mussels in the Metropolitan Water District of Southern California’s Rialto Pipeline and associated downstream pipelines by injecting EarthTec QZ at the downstream bulkhead gate slot of Devil Canyon Second Afterbay. All activities are confined within DWR’s right of way, with a 6,300-gallon Ironclad poly cube staged on concrete adjacent to the afterbay structure and surrounded by a 12x25 foot spill berm to ensure secondary containment and prevent environmental release. The project is classified under CEQA Categorical Exemption Class 1, Section 15301, as routine maintenance of an existing facility, with a Notice of Exemption signed by DWR’s Environmental Program Manager on July 15, 2026. The performance location is specifically identified as Devil Canyon Second Afterbay at Mile Marker 412.9 in San Bernardino County, California, with geographic coordinates provided, and all work is to be conducted with zero disruption to water operations. While the scope includes precise application of the treatment and safe chemical handling, no contract value, pricing details, payment terms, invoicing system, or contracting officer information are specified in the available documentation. There are no stated period of performance dates, delivery schedules, FOB terms, or formal evaluation criteria for award. Contact for the project is led by Janine Beck, Environmental Scientist, and Sara Lowry, Environmental Program Manager, with no identification of a formal Contracting Officer’s Representative, Contractor Technical Representative, or Procuring Contracting Officer. No FAR clauses, contract clauses, representations from offerors, socioeconomic certifications, unique entity identifiers, packaging specifications, or special requirements such as security clearances or OCI provisions are present in the provided materials, suggesting these details may reside in supporting or unprovided contractual documents.
