Discharge Permits Not Required to Transfer Water: Court Upholds EPA Rule

From Brownstein Hyatt Farber Shreck:

The U.S. Court of Appeals for the Second Circuit recently issued a long-awaited ruling confirming the legality of the Environmental Protection Agency’s (“EPA’s”) Water Transfers Rule in Catskill Mountains Chapter of Trout Unlimited, Inc. v. EPA, No. 14-1823, 2017 WL 192707 (2d Cir. Jan. 18, 2017). EPA’s Water Transfers Rule, promulgated in 2008, determined that “water transfers” are not activities that require a National Pollutant Discharge Elimination System (“NPDES”) permit. Under the rule, a “water transfer” is defined as “an activity that conveys or connects waters of the United States without subjecting the transferred water to intervening industrial, municipal, or commercial use.” i Water transfers are employed throughout the country and are especially important in arid Western states, where water providers seek water supplies from rivers, lakes and streams located in entirely different watersheds. …

Waters of the US rule on hold in Sixth Circuit

From Best Best & Kreiger:

[Yesterday], the U.S. Sixth Circuit Court of Appeals granted a request to hold the pending challenge to EPA’s Waters of the United States rule in temporary suspension. The case will be on hold while the Supreme Court decides whether challenges to the WOTUS rule should be brought first in the federal District Courts or whether the Sixth Circuit has jurisdiction to hear the case. … ”

Microvi and Sunny Slope Water Company Unveil World’s Most Advanced Nitrate Removal Technology

DenitroviTM to Provide Hundreds of Millions of Gallons of Safe Drinking Water Annually to Californians

Global greentech pioneer Microvi and Sunny Slope Water Company (Sunny Slope) today announced the launch of the world’s most advanced nitrate removal technology, named DenitroviTM, to provide more than 200 million gallons of potable water annually for Sunny Slope’s 30,000 households. Dentrovi is a natural nitrate-removal process with no negative impact on the environment. Moreover, the system brings significant benefits to Sunny Slope, including:

  • Up to 50 percent cost savings over every available option for nitrate removal;
  • Virtually eliminating the secondary waste stream typical of conventional technologies;
  • Proven long-term performance and easy operation.

Microvi and Sunny Slope have partnered to bring this elegant and proven solution, first implemented for remote communities in Western Australia, to help address the water crisis in Southern California.

“The Denitrovi technology is uniquely positioned to bring real solutions to the water industry,” said Dr. Fatemeh Shirazi, CEO and CTO of Microvi. “With a small footprint, virtually no waste stream and extreme energy efficiency, Denitrovi offers significant cost and operational advantages over any existing technology for nitrate removal.”

As water agencies and customers across the state know all too well, California – and Southern California in particular – must find new ways to source the water it needs. Groundwater supplies is one of those sources, but requires rigorous treatment to meet the state’s standards. Sunny Slope, like many water providers in the Los Angeles Basin, needed to find a way to treat the high levels of nitrate in its groundwater sources. In California, the United States Environmental Protection Agency has estimated that around 10 percent, or nearly 3,000 groundwater wells, are contaminated with nitrate.

The California Division of Drinking Water has issued a conditional acceptance of the Denitrovi technology for Sunny Slope, which has also received the NSF/ANSI 61 consumer safety certification.

The Denitrovi technology converts nitrate in water into nitrogen gas through a proprietary natural process that results in no byproducts or sludge production – only the safe release of nitrogen gas into the atmosphere. The technology is one of Microvi’s biomimetic water technologies, where the most effective processes of nature are used to provide significant advantages over energy intense, waste-generating and costly conventional technologies.

“Microvi’s nature-based approach to water purification is revolutionary,” said Ken Tcheng, General Manager of Sunny Slope Water Company. “We found that Microvi’s Denitrovi technology not only provided the water-quality regulators demand and our customers expect, but also solves costly waste-disposal problem of a conventional system.”

“We are proud to partner with Microvi. Our customers deserve the safest and best solutions, and we are happy to be the first to bring this innovative water technology to Southern California,” said Tcheng.

Microvi comparison with other technologies:

Microvi’s technology can be adapted to eliminate almost any groundwater pollutant – including such contaminants as perchlorate, Chromium-6 and uranium. In fact, Microvi has a suite of over two dozen technologies that are almost universal in their applications for public water agencies, water companies and others with water treatment needs.

Microvi’s inherently clean technology also equates to direct cleanup savings such as negating the need for concentrate pipelines and fewer disposal-vehicle movements, as well as non-financial benefits such as lower vehicle emission rates and less impact on landfills and the environment.

“It’s amazing to see a biological treatment system that doesn’t produce secondary waste,” said Shane Chapman, General Manager of the Upper San Gabriel Valley Municipal Water District. “Waste streams have always been a huge environmental and cost issue in water treatment—this is a long-overdue course correction for the industry. I have no doubt Microvi is showing us the future not only of nitrate removal, but the treatment of many pollutants in groundwater supplies around the country.”
