RECOMMENDATION:
Adopt Resolution No. OCSD 20-03, entitled: "A Resolution of the Board of Directors of the Orange County Sanitation District Establishing Use Charges for the 2020-21 Fiscal Year Pursuant to the Wastewater Treatment and Disposal Agreement with the Santa Ana Watershed Project Authority ("SAWPA")".

BACKGROUND
Currently, the Orange County Sanitation District (Sanitation District) invoices Santa Ana Watershed Project Authority (SAWPA) on a quarterly basis for the wastewater discharge received from the SARI line. Annually, the rates for flow, biochemical oxygen demand (BOD), and total suspended solids (TSS) are calculated based upon the fiscal year budget for treatment and disposal costs and the 1996 Wastewater Treatment and Disposal agreement. The rates calculated for each constituent for FY 2020-21 for wastewater discharge are:
FLOW $213.30
BOD $304.47
TSS $449.36
The FY 2020-21 rates result in approximately a 3.5% decrease in the Flow rate, a 4.7% decrease in the BOD rate, and a 4.7% decrease in the TSS rate. Using the 2017 Rate Study, the Sanitation District determined discharge rates for SAWPA. Changes to the allocation parameters between discharge constituents and the change in equivalent usage per EDU for each constituent resulted in rate increases that were larger than SAWPA anticipated or budgeted. SAWPA requested that the Sanitation District spread their rate increases over a two-year period to minimize the impact to their budget. SAWPA rates have now caught up with the original rate model. As a result, the FY 2020-21 rates decrease approximately 3.5% for the Flow rate, 4.7% for the BOD rate, and 4.7% for the TSS rate. These rates are separate from the ra...
