Pure Water progress cited

Point Loma plant for two main reasons.

The city uses a tube called an “outfall” to discharge the treated sewage 4.5 miles into the ocean, where it can be dispersed effectively enough to have minimal impact on wildlife.

And San Diego is spending roughly $5 billion to build a sewage recycling system that will provide one-third of the city’s water supply by 2035. That system, called

Pure Water, will reduce daily discharge from Point Loma by 100 million gallons.

To become exempt from secondary treatment and be eligible for the simplified federal waiver, San Diego must demonstrate that Pure Water can deliver on its promises and sharply reduce discharge from Point Loma.

“This bill replaces the complex and expensive secondary treatment waiver application with a simpler and more effective process if the city meets stringent water recycling milestones,” Peters said Tuesday at a news conference at San Diego’s main Pure Water plant, just east of La Jolla.

Construction of the system is expected to kick into high gear in 2021.

San Diego Mayor Kevin Faulconer called the federal bill a “pivotal piece of legislation” that would help solidify the city’s water independence.

“This bill delivers a really innovative solution to one of our city’s most complex dilemmas by simplifying the permitting process to operate the Point Loma Wastewater Treatment Plant,” the mayor said. “The regulatory certainty that this bill delivers is an absolute gamechanger.”

Peters and Faulconer stressed at the news conference that the legislation would not weaken the Clean

Water Act, modify any other federal environmental rules or change any state regulations.

Jerry Sanders, chief executive of the San Diego Regional Chamber of Commerce, hailed the legislation as good for business and the environment.

“This is a great solution that makes a lot of sense for everybody,” Sanders said, adding that it would be a relief for business leaders to stop worrying about Point Loma’s federal waiver. “This gives business certainty, and business needs certainty to thrive.”

Environmental also support the bill.

“This legislation is a critigroups cal step in ensuring significant reduction of wastewater discharges into our ocean environment,” said Matt O’Malley, executive director of San Diego Coastkeeper. “Pure Water will provide climate resilience for our city and region, ensuring water security in the face of a changing climate and increasing pressures on our existing water supplies.”

San Diego has over the years secured multiple waivers for the Point Loma plant, which began operations 57 years ago — nine years before the 1972 Clean Water Act.

Scientists at the Scripps Institution of Oceanography have long said that investing billions of dollars to upgrade the Point Loma plant would waste taxpayer money because of the 4.5-mile outfall and because the plant already conducts relatively advanced treatment.

But a federal exemption has been elusive for San Diego, partly because of objections from other cities that have been forced to upgrade their sewage treatment plants.

Peters said he thinks a key to gaining strong bipartisan support this time has been recent progress on Pure Water.

“It’s matured, it’s proven itself and now we know we can depend on it,” he said.
