Reports of Waste Discharge/NPDES Permitting

A cornerstone RBI service is National Pollutant Discharge Elimination System (NPDES) permit renewals for our Publicly Owned Treatment Works (POTW) clients. RBI staff prepare reports of waste discharge (ROWD) for renewal of waste discharge requirements (WDRs) /NPDES permits for numerous municipal wastewater dischargers in California. The ROWDs included a facility and discharge characterization, facility performance and compliance evaluation, justifications for modified monitoring and reporting requirements, and requests for consideration in the development of effluent limitations. Dischargers for which RBI has led the preparation of ROWDs include:

• City of Stockton Regional Wastewater Control Facility
• Ironhouse Sanitary District Water Recycling Facility
• City of Brentwood Wastewater Treatment Plant
• Mountain House Wastewater Treatment Plant – Mountain House Community Services District
• El Dorado Hills Wastewater Treatment Plant – El Dorado Irrigation District
• Deer Creek Wastewater Treatment Plant – El Dorado Irrigation District
• Pleasant Grove Wastewater Treatment Plant – City of Roseville
• Dry Creek Wastewater Treatment Plant – City of Roseville
• Placer County-Sewer Maintenance District 1, Sewer Maintenance District 3, Sheridan, and Applegate Wastewater Treatment Plant
• Easterly Wastewater Treatment Plant
• Hangtown Creek Water Reclamation Facility-City of Placerville
• Lake Wildwood, Lake of the Pines, and Cascade Shores Wastewater Treatment Plants-Nevada County
• Town of Windsor
• National Park Service
• City of Ione
• Colusa Industrial Properties
• City of Santa Rosa
• Los Coyotes Water Reclamation Plant and Long Beach Water Reclamation Plant-Los Angeles County Sanitation Districts
• Lincoln Wastewater Treatment and Reclamation Facility-City of Lincoln/Del Webb

Following preparation of the ROWD, RBI also assists clients during the period when Regional Water Board staff are developing the WDRs/NPDES permits by facilitating data reviews and responding to requests for supplemental information. RBI conducts thorough review and prepares detailed comments on the preliminary draft and tentative NPDES permits to identify factual corrections and to assess the appropriateness of effluent limitations, receiving water limitations, and special provision requirements. In addition, RBI staff prepare “infeasibility analyses” needed to justify inclusion of compliance schedules in the NPDES permit or outside order (e.g., time schedule order or cease and desist order) for our clients.
