The memorandum discusses discharge regulations and their potential impacts on the San José-Santa Clara Regional Wastewater Facility (RWF). It outlines the RWF's role as a major wastewater discharger, its regulatory framework, and the evolving nature of wastewater and air quality regulations. The document emphasizes the importance of proactive engagement with regulators to manage operational and capital costs, particularly in light of new nutrient load caps and contaminants of emerging concern (CECs). It highlights ongoing studies and efforts to address nitrogen reduction and the impact of PFAS and flea and tick treatment pesticides on the environment.
Key points
The RWF serves a population of 1.5 million and is the largest advanced wastewater treatment plant in the western United States.
The facility is regulated under NPDES permits and Title V of the Clean Air Act.
Recent harmful algae blooms have prompted regulators to require reductions in nitrogen loads from wastewater treatment plants.
The RWF has achieved an 85% nitrogen reduction but faces challenges in maintaining this as population increases.
Emerging contaminants like PFAS and certain pesticides pose regulatory challenges and environmental risks.
The RWF is participating in regional studies to evaluate opportunities for reducing nitrogen discharges.

T&E AGENDA: ITEM: TO: TRANSPORTATION AND ENVIRONMENT COMMITTEE 06/05/23 (d) 1 FROM: Kerrie Romanow SUBJECT: DISCHARGE REGULATIONS AND DATE: May 15, 2023 POTENTIAL IMPACTS TO THE SAN JOSÉ-SANTA CLARA REGIONAL WASTEWATER FACILITY Approved Date 5/26/23 RECOMMENDATION Accept a report on future wastewater and air discharge regulations and their potential impacts to the Regional Wastewater Facility. BACKGROUND The San José-Santa Clara Regional Wastewater Facility (RWF) is the largest wastewater discharger in the San Francisco Bay and the largest advanced wastewater treatment plant in the western United States, serving a population of 1.5 million people and over 17,000 businesses across eight cities and the County. From industrial dischargers to residents and restaurants, the RWF is responsible for cleaning wastewater to the highest standards before it is discharged through the Artesian Slough to the shallow waters of the Lower South Bay. Since 1956, the RWF has continually treated the majority of Silicon Valley’s wastewater and protected public health and the San Francisco Bay environment. The RWF is sized and permitted to treat an average of 167 million gallons per day during dry...

The presentation discusses discharge regulations and potential impacts related to the San José-Santa Clara Regional Wastewater Facility, which has been operating since 1956 and serves 1.5 million people across 8 cities and the County. It outlines various regulatory permits concerning air and water quality, including their effective dates and expected reissuance. The presentation highlights updated regulations on nutrient limits due to an algae bloom in August 2022 and mentions contaminants of emerging concern like PFAS and microplastics. It also references new BAAQMD regulations and a South Bay odor study conducted in 2020/21, with a draft report issued in 2022. The conclusions emphasize the importance of monitoring, engaging with regulators, and maintaining proactive compliance efforts.
Key points
The Regional Wastewater Facility has a capacity of 167 MGD and covers a 2,600-acre site.
It serves 1.5 million people and 17,000 businesses.
The facility is subject to multiple regulatory permits for air and water quality.
New nitrogen limits are expected in 2024 due to an algae bloom in August 2022.
Contaminants of emerging concern include PFAS and microplastics.
New BAAQMD regulations include rules on toxic air contaminants and sewage treatment.
A South Bay odor study was conducted in 2020/21, with a draft report issued in 2022.
Limitations
The text does not provide specific dates for the algae bloom or the South Bay odor study.
There are unresolved placeholders regarding specific details of the permits and regulations.
