A green roof has been installed on our downtown Seattle office building

By Bruce Duncan

The Region 10 Science Steering Council recently hosted our first “Science Café” to discuss how our Seattle office building is working toward LEED (Leadership in Energy and Environmental Design) certification as we undergo a major remodel. LEED is a third party certification program administered by the U.S. Green Building Council that focuses on the design, construction and operation of high performance green buildings.

I moderated the meeting and want to share some of the discussion. The first presentation focused on the building’s infrastructure (its green roof, pipes, and pumps) and participation in a private/public group committed to significantly reducing energy consumption by 2030.

Next, was a detailed look at the upcoming remodel of EPA space in the building and how we might get to a LEED “Platinum” rating. Presenters showed how the remodel is a unique opportunity to capture environmental benefits, energy efficiencies and cost savings. EPA is pursuing projects in:

• sustainable site selection
• water efficiencies
• energy and atmosphere
• materials and resources
• indoor environmental quality
• innovation and design process
• regional priorities that further sustainability.

Each project generates points toward the LEED rating.

Our last discussion centered on what we can do in our individual spaces to be sustainable by recycling and reducing our use of resources.

Interesting information to me from the Q&A sessions included:

• What is the cost to building management to register for LEED certification?

Approximately $10,000.

• How is the return on investment working out for the building upgrade to LEED?

The payback horizon is reasonable for those components that do have a quantifiable return on investment. As we move forward, we would be comfortable with a 5 year payback horizon.

• What are we doing to improve our office space that does not count toward LEED rating?

One example is the computer server room, which will be located to take advantage of cool outside air near windows.

What I liked most about our Science Cafe was seeing the linkage from my own office space and habits, to EPA’s space, to our building overall and how it sits within a self-led management community committed to sustainability.

Yesterday I was in Warwick Township and Lancaster County, Pennsylvania, a rural community that has been a model for resource conservation and sustainable economic growth. This was one of many visits EPA officials have made to connect with rural communities. I have had the chance to sit down with growers in Georgia, visited California’s Central Valley and toured farming operations with Agriculture Secretary Tom Vilsack in Iowa. Along with my fellow EPA officials, we have connected with hundreds of farmers, business owners, local leaders and rural residents to talk about commonsense efforts to strengthen their economies and protect their health and the environment.

American farmers and ranchers depend on clean air, safe and abundant sources of water and healthy lands. That’s why farming communities have taken incredible steps to steward the environment their jobs and economy thrive on.

In the last 30 years, agricultural producers have worked with government officials and local conservation groups to reduce soil erosion by more than 40 percent. At the same time, agriculture has gone from being the leading contributor to wetland loss to leading the entire nation in wetland restoration efforts. In Lancaster, local efforts have managed to preserve upwards of 80,000 acres of farmland, and Warwick Township was named Conservationist of the Year by the Chesapeake Bay Foundation for its work to prevent runoff from polluting the watershed.

These are just a few of the examples I’ve seen. In California’s Central Valley — an area responsible for some $24 billion in agricultural activity — I visited a farmer who re-vamped his irrigation system to reduce water use and save money, while another grower who was transitioning to new irrigation pump motors that reduced air emissions on his farm.

In Iowa, I joined Secretary Vilsack at a cattle operation where a rotational grazing system helps protect soil and water quality, and met a farmer who has used no-till farming and a precision sprayer for years to minimize pesticide use and runoff from his soybean fields.

America’s rural communities have also been part of innovative solutions for our entire economy. The Renewable Fuel Standard EPA finalized last year will encourage farmers to continue to work with industry to innovate and produce clean renewable fuel. It will help secure our nation’s energy future, replacing our dependence on foreign oil with clean, homegrown fuels produced by America’s farmers. At the same time, it will create jobs, and is expected to increase farmers’ income by an estimated $13 billion annually.

These meetings with farmers on their land are also a great opportunity to get outside the Washington, DC echo chamber and address myths and other inaccuracies they might be hearing about the EPA. For example, months ago rumors flew around that, under a law passed by Congress, EPA was considering treating spilled milk like an oil spill. This was never the case; in fact, our efforts were focused on exempting dairy producers from regulations that should not apply to them. Thanks to work with the dairy industry and the agricultural community, we obtained a formal exemption for all milk and milk products, a change that could save farmers up to $140 million.

As we confront the major environmental challenges of our time — combating climate change, reducing soil erosion, and ensuring an ample supply of clean water for our families and food production — farmers have an important opportunity to lead the way. That is why I will continue to visit with communities like Lancaster to see the best practices at work and speak directly with the local residents.

For each month in 2009, the Year of Science — we will pose a question related to science. Please let us know your thoughts as comments, and feel free to respond to earlier comments, or post new ideas.

The Year of Science theme for September is Biodiversity and Conservation. Biodiversity is a catch-all term that refers to the variety of life at all levels, from the range of genes within in a breeding population (more genetic diversity helps to prevent inbreeding problems), to how many different species there are, all the way to the variety of different ecosystems. EPA scientists are exploring how biodiversity is linked to human health and well being.

How do you think biodiversity affects you?

The average family in the United States uses 400 gallons of water every day. We use it to cook, clean, drink, garden and for many other indoor and outdoor activities. Water is definitely an important resource to us all and is essential to our everyday lives. Unfortunately, to get this water to our homes it takes a lot of energy. Two to three percent of the world’s energy consumption is used to treat and pump water to our homes. And, the percent of energy that we need to treat and pump our water changes from region to region depending on how much the region consumes. In California, for example, about 20 percent of the state’s energy is used to treat and pump its water. Therefore, in order to conserve energy, it is important to conserve our water use within our homes. The EPA estimates that by practicing water conserving techniques, you can reduce your water use by 20–30 percent. By reducing your water use, you will be able to reduce your homes energy use and also be able to save some money and reduce your carbon footprint. And, it’s very simple to reduce your water use!!! Some simple things that you can do include:

• Listen for dripping faucets and running toilets. Fixing a leak can save 300 gallons a month or more.
• Turn off the water while brushing your teeth and save 25 gallons a month.
• Run your clothes washer and dishwasher only when they are full. You can save up to 1,000 gallons a month.
• Find out more ways you can conserve water

Can you think of other things we can all do to conserve water? Be sure to let us know so we can all save energy by practicing water conservation.

On September 23, 2008 I was touring the Upper Santa Cruz River with Amy McCoy of the Sonoran Institute as my watershed tour guide. The trip was awesome; I never knew that the southeast corner of Arizona was so beautiful.

Towards the end of our day trip Amy was anxious to get back to Tucson to attend an important City Council meeting, I didn’t know it until later that it was the vote on the Grey Water Ordinance that Amy was trying to make it to. The Sonoran Institute, using EPA Targeted Watershed Grant funds, helped to put together the ordinances for the City Council vote.

Because there’s so little surface water in the Tucson area, the city’s major water source has always been groundwater. The Grey Water Ordinance is aimed at reducing the use of scarce drinking water to irrigate desert landscapes. The city estimates that 45 percent of water use is for landscaping, and using rainwater and gray water would greatly reduce this.

The ordinance requires rainwater harvesting plans and capturing systems for any new commercial building built after June 1, 2010. The Ordinance requires that new homes built after that date be plumbed for gray water irrigation systems. This means having a drain for sinks, showers, bathtubs, and washing machines separate from drains for all other plumbing, to allow for future installation of a gray water system.

A key factor contributing to the success of this ordinance was the involvement from the entire community, from plumbers and landscapers to the Friends of the Santa Cruz River, they all added their support for the ordinances success. In addition to the community support, an EPA grant helped finance some of the work towards creating the ordinance language.

The City of Tucson was selected for a Pacific Southwest Regional Environmental Award and on the day of the awards ceremony, I had no idea who was coming to accept the award, but had heard that Councilman Rodney Glassman was coming. He was the driving force behind the ordinances, but I had no idea what he looked like. Well, Rodney is about 6’8”, and super energetic, really hard to miss. Once we connected it was great to sit and chat with him, he is very passionate about the ordinances, Tucson, and Arizona. Way to go Councilman Rodney Glassman and the City of Tucson!
