Ultra-sustainable zHome

News Release from EPA Region 10:

Ultra-sustainable zHome becomes the first community of WaterSense labeled new homes in the Nation

(Seattle – Jan. 25, 2012) zHome – the ultra-sustainable, 10-unit townhome development in Issaquah, WA that is redefining the future of housing – is also the first community in the Nation in which every home has earned the WaterSense label for new homes. EPA’s WaterSense program is modeled after its highly successful Energy Star program. The goal of WaterSense is to significantly reduce water use nationwide to save water resources for future generations.

A home that is certified to earn the WaterSense label will use at least 20 percent less water than a standard, newly-constructed home and the high-efficiency WaterSense labeled fixtures perform as well or better than their traditional counterparts. The benefits of the certification include:

• Lower utility bills for future residents
• Reduced strain on water and wastewater systems
•  More water left in streams and aquifers for salmon, recreation and other uses
• Fewer greenhouse gas emissions due to reduced energy demands from water treatment and delivery

zHome was designed to push the limits of sustainable, production housing. It is the first townhome, zero-energy, carbon-neutral community in the United States, and also received the Forest Stewardship Council’s 2011 award for the best residential project in North America.

In addition, zHome strove to demonstrate a multitude of water-efficient technologies, with a net reduction of 70 percent in potable water use compared to a typical King County home. Cascade Water Alliance provided WaterSense labeled toilets, showerheads, and bathroom faucets, as well as innovative, real-time use monitors for every unit to ensure maximum efficiency. Each zHome unit also includes a rainwater harvesting tank (ranging in size from 1,000- to 1,800-gallons) that is used for clothes washing and toilet flushing.

“EPA is proud to recognize the zHome project, built and developed by Ichijo USA and Seattle builder Matt Howland, as one of the leaders in the Pacific Northwest in helping to advance water efficiency,” said Paula vanHaagen, EPA’s Manager, Grants and Planning Unit in Seattle.

zHome was brought to life through a highly collaborative public/private partnership spearheaded by the City of Issaquah, in conjunction with Built Green, King County, Port Blakely Communities, Puget Sound Energy and the Washington State University Energy Program.

“We are extremely excited that the zHome units received the new WaterSense New Homes certification,” said Issaquah Mayor Ava Frisinger. “We hope zHome inspires homebuilders and homeowners to take advantage of the same water-saving benefits with their projects.”

Cascade Water Alliance, a long-time WaterSense promotional partner, is a non-profit corporation with the goal of providing safe, clean, and reliable water to its 400,000 residents and 22,000 businesses. Cascade is made up of the cities of Bellevue, Redmond, Kirkland, Issaquah, Tukwila, the Covington Water District, and the Sammamish Plateau and Skyway Water and Sewer Districts.

EPA Awards Innovative Plating Company

EPA Awards Innovative Plating Company in Clovis for Significant Reductions of Toxic Chemicals

Zero Discharge Facility Reduces 9,000 Pounds of Lead and Hex-chrome, Protects Workers, Public Health

SAN FRANCISCO – The U.S. Environmental Protection Agency today recognized Valley Chrome Plating for its achievements in environmental and worker protection under the National Partnership for Environmental Priorities (NPEP) program.  The plating company, located in Clovis, Calif., successfully substituted lead anodes and hexavalent chromium with less harmful alternatives. These advancements have resulted in the reduction of these harmful chemicals by 9,000 pounds—significantly protecting the environment and worker exposure.

“This is a great example of how a company can protect its employees and the environment while growing its business and providing important local jobs,” said Jared Blumenfeld, EPA’s Regional Administrator for the Pacific Southwest. “Removing thousands of pounds of lead and chromium-six from its products ensures a safer environment for Valley Chrome Plating’s workers and the community.”

In 2009, the company eliminated the use of hexavalent chromium and replaced it with the more environmentally friendly trivalent chromium. That same year, Valley Chrome also replaced its lead anodes with safer graphite anodes. The switch to graphite and trivalent chromium has eliminated 3,000 pounds of lead waste and 6,000 pounds of hexavalent chromium from its waste stream.

In addition to altering the materials used its truck bumpers and accessories; Valley Chrome discharges zero wastewater to the public sewers through recycling and the underground plumbing that captures roof run-off from the facility for re-use. This system collects up to 100,000 gallons of rain water that is then used by the facility as part of its cleaning and finishing processes. Valley Chrome also installed ion exchange waste reduction systems in its manufacturing and plating operations, further reducing pollution associated with trivalent chromium as well as nickel plating.

These innovations saved this family-owned company thousands of dollars in waste treatment costs, hauling fees and reduced energy consumption and still allowed the company to compete in the global market.

Hexavalent chromium is associated with irritation to the skin, nose, eyes and throat and more serious complications. Lead is a toxic metal used in plating tanks as anodes. Lead is tied to  a range of health effects, including behavioral problems, learning disabilities, seizures and death. Children six years old and under are at most risk.

NPEP was a voluntary program fostering partnerships between regulatory agencies and manufacturers, commercial companies, and other facilities to reduce the use and release of highly toxic chemicals. NPEP officially ended in 2011. The NPEP partnership encouraged innovative thinking about conservation of our natural resources and ways to substitute, reduce, reuse and recycle..

Today’s announcement was part of Regional Administrator Jared Blumenfeld’s two day “Whistle Stop Tour” of San Joaquin Valley. For more information on his overall visit, today’s event and photos, please visit: http://www.epa.gov/region9/mediacenter/sjv-tour/

Los Alamos National Laboratory and Zero Wastewater Discharge

News Release from Los Alamos National Laboratory:

LANL achieves milestone on path to zero wastewater discharge

Improved compliance while recycling millions of gallons of industrial wastewater

LOS ALAMOS, New Mexico, January 20, 2012—Millions of gallons of industrial wastewater will be recycled at Los Alamos National Laboratory as the result of a long-term strategy to treat wastewater rather than discharging it into the environment.

The U. S. Environmental Protection Agency, which issues permits for industrial and sanitary wastewater discharges, recently approved the removal of four more outfalls from the Laboratory’s permit. (An outfall is where wastewater from Lab operations is discharged down canyons.)  Only 11 outfalls remain, down from 141 in 1993. 

"One of the objectives of our Environmental Management System is to reduce liquid discharges to a single outfall by the end of 2012," said Dennis Hjeresen, Division Leader of the Environmental Protection Division at the Lab. "Removing four more facilities from our permit is an important step toward reaching that goal."

The wastewater comes from many places at the Laboratory and does many things.  It cools the Los Alamos Neutron Science Center (LANSCE), one of the Lab’s premier science research facilities, and the Strategic Computing Complex, which creates world-class high-performance computing systems. The water also cools the Lab’s power plant and comes out of the sanitary plant that treats water from toilets and sinks.

The treated sanitary wastewater and water flushed from cooling towers is transported to the Lab’s Sanitary Effluent Reclamation Facility (SERF). It then can be reused in cooling towers around the Lab.
"The SERF should be recycling up to 300,000 gallons per day by the summer of 2012," Hjeresen said.
