Moisture Control: A Key Factor for a Healthy Indoor Environment

EPA’s mission is to protect public health and the environment. While a large part of this mission involves protecting the air and water outdoors, we also need to make sure that people have the tools and information they need to keep the air clean in the areas where they spend up to 90 percent of their time – indoors.  And the agency is doing that through voluntary actions and information sharing, not regulations.

Some of the biggest threats to indoor air quality stem from moisture issues. Leaking roofs, plumbing problems, condensation issues, poor indoor humidity control, and lack of drainage around the base of buildings are commonly reported causes of moisture problems in the United States. Not only does excess moisture damage the structural integrity of buildings, it can increase people’s exposure to mold and other biological contaminants. Such exposure is associated with increases in the occurrence and severity of allergies, asthma and other respiratory illnesses. And, climate change will only worsen these issues as we see an increase in the frequency and intensity of severe storms and flooding that damages homes and buildings.

The good news is moisture problems in buildings can be controlled with steps that can be taken to make buildings more moisture resilient. For example, design landscaping to slope away from building foundations. Doing simple steps like this can prevent economic losses on multiple fronts by avoiding building damage as well as negative health impacts as it makes our indoor spaces healthier and more comfortable.

That’s why EPA pulled together experts from across the country to develop new, practical, state-of-the-art guidance for controlling moisture in buildings.  EPA recently published the result of that work, entitled, “Moisture Control Guidance for Building Design, Construction and Maintenance.” Encouraging voluntary actions to control moisture and other indoor contaminants will be a critical part of our climate adaptation strategy for ensuring healthy buildings as we continue to address our changing climate.

The key to controlling mold and many other indoor contaminants is moisture control.  It’s a simple concept, but it takes attention to detail to get it right. That’s why this practical guidance will be helpful to people who design, build or keep buildings working. Building professionals who incorporate the principles provided in this guide can enhance the health and productivity of Americans and the sustainability and resiliency of our communities. While this guidance is primarily for building professionals, EPA also offers mold and moisture control guidance for homeowners and residents at

With summer upon us, including the opportunity to once again enjoy the great outdoors, we are reminded of the many important roles of our nation’s water bodies. Whether it be fishing, swimming, boating, a source of drinking water, or just enjoying the view, we need to be reminded that protecting our nation’s water bodies must be a priority for each and every one of us. While there are traditional ways for ensuring that water bodies are protected by issuing permits and taking enforcement, EPA is working ever more closely with local governments, organizations and the public on more collaborative ways involving voluntary initiatives and innovative partnerships. One of the things I enjoy most about being the Regional Administrator for EPA’s Mid-Atlantic Region is seeing these partnerships at work.

Several weeks ago, on my way to deliver a speech about President Obama’s Climate Action Plan at the Virginia Military Institute’s 25th Annual Environmental Symposium in Lexington, Virginia, I drove through the naturally spectacular Shenandoah Valley to visit Waynesboro, Virginia and tour Ridgeview Park.

Remember the days before SPF when you weren’t so sure how long your sun screen would protect you from the sun’s harmful rays? Maybe I’m dating myself. I burn easily and had no idea how to protect myself, what to apply, and when to reapply suntan lotion.

Many of us continue to experience the same problems when trying to decide which mosquito repellent to use and when to reapply it. And what about ticks?

Nowadays we know that both mosquitoes and ticks carry some serious diseases. Mosquitoes can give you West Nile virus and St. Louis encephalitis, and ticks can transmit serious diseases like Lyme disease and Rocky Mountain spotted fever. Like sunscreens, mosquito and tick repellents can provide important protection against potentially lifelong health problems.

Saving Energy and Money: Go Team Go!

Cross-posted from “It’s All Starts with Science”

Introduction By EPA Administrator Gina McCarthy

We know that a strong economy and a healthy environment go hand-in-hand. That’s why, today, we announced that 21 small businesses in 14 states are receiving funding from the EPA to develop and commercialize innovative, sustainable technologies to address current environmental issues. Read more about one recipient, also a former winner of our agency’s People, Prosperity, and the Planet award, whose company is challenging kids to get involved and spurring competition to lower energy consumption in schools.

By Lek Kadeli

Spirited competition between local schools is a time honored tradition. From the football and soccer teams to the debate club, nothing beats taking on your arch rival to spark school spirit, get the neighbors talking, and build community pride.

That spirit of competition has helped schools here in the District of Columbia save more than 76,000 kilowatt-hours of electricity, thanks to Lucid—an EPA-supported small business started by previous winners of the agency’s People, Prosperity and the Planet (P3) award.

The schools vied to see which could most dramatically reduce their energy consumption as part of the three-week “Sprint to Savings” competition. The DC Green Schools Challenge set up the competition to help schools conserve energy and save money while “engaging students in real-world learning opportunities.”

To monitor their progress and take action, students used Lucid’s “Building Dashboard,” a software program that monitors a building’s energy and water consumption in real time and presents that information in easy-to-understand graphic displays on computer screens or other devices.

Students were able to use Building Dashboard installed at their schools to gauge their progress in 15-minute intervals and help the school take corrective action, such as switching lights off when not needed, shutting down unused computers and monitors, and turning the heat down after hours. A District-wide leader board helped them keep an eye on the competition.

The idea for a data monitoring display system begin when the now principal partners of Lucid were students at Oberlin College. In 2005, their prototype won an EPA P3 Award. The P3 program is an annual student design competition that supports undergraduate and graduate student teams to research and design innovative, sustainable methods and products that solve complex environmental problems. Since then, there’s been no looking back!

Today, we are thrilled to announce that Lucid is among 20 other small businesses—including two other former P3 winners—selected to receive funding as part of the EPA’s Small Business Innovative Research (SBIR) program. The program was designed to support small businesses in the commercialization as well as the research and development of technologies that encourage sustainability, protect human health and the environment, and foster a healthy future. Environmental Fuel Research, LLC, and SimpleWater, LLC are the other two former P3 winning teams.

Thanks to Lucid, Environmental Fuel Research, LLC, SimpleWater, LLC and the other innovative small businesses we are supporting today, winning ideas are bringing products to the marketplace that protect our environment while sparking economic growth. I’ll bet that even arch rivals can agree that’s a win for everyone.

Building Partnerships to Invest in Communities and Redevelopment

2014 July 14

We recently announced our continued commitment to invest in communities to jump-start local economic redevelopment through the award of the brownfields assessment, revolving loan fund and cleanup (ARC) grants. Since the first pilot grants were issued in the 1990s, communities across the country have successfully utilized these EPA grant funds to address the reuse and redevelopment of idle, contaminated properties. These grant awards represent a new start, a chance to empower communities to return once blighted neighborhoods into opportunities to generate jobs and spur economic growth. Many projects, past and present, which received ARC grants promote a clean environment and redevelopment.

Partnerships between neighborhoods, local developers, and governments are essential for surrounding communities to acquire the resources needed to meet revitalization goals. EPA’s Brownfields Program strives to expand the ability of all communities to recycle vacant and abandoned properties for new, productive reuses. By leveraging private resources, and the resources of other federal and state programs, communities can support site cleanup as part of the redevelopment process. EPA cannot meet every community site reuse need without the support of strong partnerships leveraging a range of resources. We want every community to have access to the resources they need to address brownfields and use them as catalysts to stimulate new economic activity and jobs, and serve as the foundation for an improved community quality of life.

Other projects these grants have affected include:

  • Cheyenne River Sioux Tribe located in South Dakota plans to clean-up the Old Swiftbird Day School and reuse the site as an eagle sanctuary. The tribe leveraged funding to oversee the project completion and leveraged $1.3 million from the Tribal Equitable Compensation Act;
  • Indianapolis’ first permanent supportive housing for homeless veterans opened on the site of a former iron foundry brownfield remediated by the City; and
  • The City of Waterloo, Iowa began a renewal initiative on many abandoned commercial and industrial properties with perceived contamination.
  • The crime-prone Greg Grant Park in Trenton, NJ was removed and replaced with award-winning housing for low income residents.
  • The investigation of the Sugar Hill site in Harlem, NY led to a remediation project that was completed in November 2012, creating a Children’s Museum of Art and Storytelling that will open later this year.
  • Read all our brownfields success stories.

These are just some of many ARC grant success stories and I’m proud of the visible impacts these grants have had in communities across the country. Since the beginning of the EPA’s Brownfields program in 1995, cumulative brownfield program investments across the country have leveraged more than $21 billion from a variety of public and private sources for cleanup and redevelopment activities. This equates to an average of $17.79 leveraged per EPA brownfield dollar expended. These investments have resulted in approximately 93,000 jobs nationwide. To date, the brownfields program has assessed over 20,600 sites, and made over 30,000 acres ready for reuse.

I encourage you to share your thoughts in the comments:

  • What additional actions do you think EPA could take to further encourage the leveraging of private resources for brownfields redevelopment?
  • What steps can EPA take to build more partnerships and align resources in order to advance brownfields projects?
  • What other community uses or needs should EPA consider in project implementation?

Smart Growth Approaches for Flood-Resilient Communities

2014 July 10

4:30 pm EDT

Smart Growth Program LogoLast month marked the first year anniversary of the President’s Climate Action Plan. As part of that plan, EPA has been working to prepare the United States for the many impacts of climate change, including flooding. Many communities across the country are recognizing the need to prepare for more frequent and more powerful storms; others are already dealing with storm damage and looking for ways to recover that deliver the best long-term results.

Smart growth approaches to development can help communities become more resilient to flooding by protecting vulnerable undeveloped lands, siting development in safer locations, and designing development so it is less likely to be damaged in a flood. Recognizing this, the state of Vermont came to EPA’s Office of Sustainable Communities and the Federal Emergency Management Agency (FEMA) for assistance in 2012 following Tropical Storm Irene, which damaged many communities across the state. Together, we helped several state agencies and communities in the Mad River Valley of Vermont assess how they could incorporate smart growth principles into their policies, development regulations, and hazard mitigation plans to make them less vulnerable to extreme floods. EPA’s Office of Sustainable Communities recently released a report and a handy checklist that communities seeking to prepare for or recover from a major flood can use to assess whether their codes, policies, and regulations can help them withstand floods.

The report and checklist cover a wide range of activities. Not all of these activities will be appropriate for each community. I encourage community leaders to consider them all, and then choose the activities that work best for their local conditions and circumstances.

Here are some general steps communities can take to improve their flood resilience:

  • Update and integrate community or comprehensive land use plans with hazard mitigation plans to ensure they are coordinated and that they prioritize planning for new growth in safer areas.
  • Audit policies, regulations, and budgets to ensure consistency with flood-resilience goals outlined in community plans and hazard mitigation plans.
  • Amend existing policies, regulations, and budgets or create new ones to help achieve the flood-resilience goals outlined in plans.

Here are some specific local land use policy options communities can consider:

  • Conserve land and discourage development in particularly vulnerable areas along river corridors, such as flood plains and wetlands.
  • Where development already exists in flood-prone areas, take steps to protect people, buildings, and facilities from flooding risks.
  • Plan for and encourage new development in areas that are less vulnerable to future floods.
  • Manage stormwater using watershed-wide stormwater management and green infrastructure approaches to slow, spread, and infiltrate floodwater.

State agencies can also partner to support recovery and flood-resilience planning. Specific actions states can take to improve their flood recovery and resilience efforts include:

  • Auditing all state programs to determine how well they help communities achieve flood-resilience goals.
  • Developing a comprehensive recovery plan before the next flood happens.
  • Developing a personnel plan that delineates who will assist with post-disaster recovery.

The checklist and report come on the heels of President Obama’s announcement on June 14 of a new National Disaster Resilience Competition, which will provide nearly $1 billion in funding from the U.S. Department of Housing and Urban Development’s Community Development Block Grant-Disaster Recovery funds to help communities that have experienced natural disasters rebuild and prepare for future disasters. The Notice of Funding Availability for the competition will be posted on

The Office of Sustainable Communities will host a webinar on smart growth approaches for flood-resilient communities with FEMA and the state of Vermont on Wednesday, August 13, from 1:00-2:30 EDT. Find details at

Competitors team up to power down in this year’s Energy Star Battle of the Buildings

2014 July 10
Gina McCarthy

By Gina McCarthy

What if the key to driving down energy use in commercial buildings came down to one simple idea: Teamwork. We see the power of teamwork all around us. In sports, individuals come together to push each other, help each other, and find out how to work together for the maximum benefit. At work, we achieve more by working together than we could ever achieve alone. So why not take this concept into the realm of commercial building energy use?

This year, as part of the fifth-annual Energy Star Battle of the Buildings, competitors are harnessing the power of teamwork to reach new heights in energy performance. They’ll build on each other’s successes, learn from each other’s mistakes, and together, find new ways to unlock energy savings.


But how much can one building really save anyway? The answer is, a lot. The buildings we see in our communities every day—offices, schools, hospitals, stores—use nearly 20% of our nation’s energy. And it costs more than $100 billion annually to keep them running. But did you know that the average building wastes 30% of the energy it consumes? People leave lights on. Equipment breaks.
Filters go unchanged for months, or years.

That’s about to change for the more than 100 teams and their respective buildings that are participating in this year’s competition. With a little competitive spirit and a lot of teamwork, these buildings are knocking down barriers and building momentum for positive change. See who’s competing near year, watch their progress, and share the excitement at

In the only coast-to-coast competition of its kind, dozens of different types of commercial buildings are facing off in this year’s Energy Star Battle of the Buildings. This year’s theme, “Team Challenge,” features teams of five or more buildings who will work together to reduce their collective energy use as much as possible over the course of a year. For example, “Team Staples” includes 17 Staples stores, while 15 Whole Foods stores will support each other as part of “Team Whole Foods Market.” In a county outside Wilmington, Del., 13 elementary schools will compete as part of a team, and they’re going up against their county’s five middle schools and six high schools. In Hillsborough Country, Fla., fire stations will team up to compete against libraries.

Competitors will measure and track their building’s monthly energy consumption using EPA’s Energy Star online energy measurement and tracking tool, Portfolio Manager. Over the course of the competition, building teams will work to optimize or upgrade equipment, retrofit lighting, and change occupants’ behaviors—all with help from Energy Star. The team that reduces its buildings’ average energy use the most, on a percentage basis, over a 12-month performance period, will be declared the winner. 700 buildings are also competing in a special water reduction category, and will work with EPA’s WaterSense program to apply best practices for commercial building water management.

EPA will maintain a website devoted to the competition, featuring a list of the competitors and their starting, midpoint, and final standings, a live Twitter feed where competitors will post updates on their progress and an interactive map of the competitor’s locations. Midpoint results will be posted in October, with the winner announced in April 2015.

Products, homes and buildings that earn the Energy Star label prevent greenhouse gas emissions by meeting strict energy efficiency requirements set by the U.S. EPA. From the first Energy Star qualified computer in 1992, the label can now be found on products in more than 70 different categories, with more than 4.5 billion sold over the past 20 years. Over 1.5 million new homes and 23,000 buildings have earned the Energy Star label.

From Cutting Edge to Commonplace

By Cynthia Giles

I’ve dedicated my career to working with state, local and tribal partners to enforce environmental laws to protect American communities from pollution. Looking back, we’ve come a long way in how we measure for pollution and take action to curb it. Years ago, accounting for air pollution from refineries, for instance, was unreliable and burdensome. It relied in large part on estimates, often done by the refineries themselves, which often undercounted actual emissions and the risks posed to neighbors. In those days, fully understanding refinery emissions would have required taking air samples one-by-one across many potential sources.

Over the past decade, new technologies and innovative solutions have significantly improved our enforcement and compliance efforts. Through EPA’s Next Generation Compliance strategy, we’re building these tools into settlements with companies, pushing their development and implementation in communities across America.

Hundreds of ideas, one proposal: How EPA developed the Clean Power Plan

2014 July 7
Janet McCabe

July 7, 2014
11:14 am EDT

With all the coverage of EPA’s Clean Power Plan, I wanted to take a few minutes or a few hundred words to tell you about the process we followed to write our 645-page proposal. The bottom line is that it is the product of many months of hard thinking and data analysis by EPA staff and substantial input from literally thousands of thoughtful stakeholders.

President Obama Announces His Climate Action Plan

On June 25, 2013, President Obama announced his Climate Action Plan and issued a Presidential Memorandum directing EPA to use section 111(d) of the Clean Air Act to cut carbon pollution from existing power plants. This wasn’t the first time the agency had considered using section 111(d). Since the 2007 Supreme Court decision in Mass vs. EPA, the agency has been considering its authorities to address carbon pollution under the Clean Air Act. In fact, a 2008 advanced notice of proposed rulemaking examined a number of regulatory approaches including section 111. And using Section 111d made a lot of sense, since the Clean Air Act established it for addressing existing sources of pollution not covered by other parts of the Act.

What We Heard

Immediately following the President’s announcement and at his direction, the agency embarked on an extensive public outreach process—one that reached thousands of people through hundreds of meetings, listening sessions, video conferences, phone calls, conference calls, and almost two thousand emails from individuals across the country. We talked to states, power companies, local communities, environmental groups, associations, labor groups, Tribes, and many more. This process was a critical component in developing this rule because it helped focus our attention on what was going on—on the ground—in states and communities across the country, and it generated public discussion and ideas from numerous groups and individuals that helped inform our thinking.

So, What Did We Hear?

  • We heard that flexibility is key, so we maximized flexibility in our proposal letting states chart their own course that builds on the progress they’ve already made.
  • We heard that states could cut pollution more cost-effectively if we, and they, looked at the energy system as a whole, so we allowed states to look across the system to find reductions.
  • We heard that the power sector is interconnected and it crosses state lines, so in addition to proposing that each state develops its own plan, we also proposed to allow states to work together to develop plans, depending on what suits their situation.

We didn’t just hear these ideas from one group or even one sector; we heard them from just about everyone. And what emerged was a collection of ideas—or threads—that guided us as we crafted our proposal.

Weaving it All Together

Over the past year, dozens of EPA scientists, lawyers, economists, health experts, policy analysts, and many others wove the threads we heard along with our own extensive analysis, data, and information into the proposal we announced on June 2.  If you look closely you may see some of the threads you contributed or heard throughout the outreach process.

One of the great values of the transparent process we used, and will continue to use, to collect input from the public is that no one person or group has the only, or best, idea.  It takes all of us contributing our information and suggestions to fashion a good, workable rule that meets the requirements of the law and achieves meaningful public health and environmental benefits.  And EPA’s proposal does just that. It is a proposal that is based on what’s going on in the real world, cuts carbon pollution, protects public health and moves us toward a cleaner, healthier environment for future generations, while supplying the reliable affordable power needed for economic growth.

Protecting Beachgoers is Top Priority for EPA

2014 July 3
Nancy Stoner

1:48 pm EDT

People swim at a beach with a city skyline in the distance.Summer’s here, and it’s time to celebrate the 4th of July! Many of us will celebrate by going to the beach –over 307 million of us took trips to the beach last year, according to the U.S. Lifesaving Association. This is a good opportunity for me to tell you about EPA’s work to protect swimmers at America’s beaches.

Protecting public health is a top priority for EPA, and we rely on the best science to do that. We also work closely with our partners at the state and local level, to make sure we learn from their experience and help support their programs.

Setting Safer Standards for Recreational Water

In 2012, we recommended new water quality criteria to better protect the health of Americans engaging in a variety of recreational activities such as swimming, surfing and paddling. The criteria are based on the latest science and improve protection of public health by addressing a broader range of illness symptoms, better accounting for pollution after heavy rainfall, ensuring equal protection for coastal and Great Lakes waters, encouraging early alerts to beachgoers and promoting rapid water testing.

States and local public health officials use recreational criteria to determine when water quality meets public health standards for safe recreation. The criteria also provide optional thresholds for when to issue swimming advisories or beach closures.

Encouraging States to Incorporate the Safer Standards

This year, we are working to update our guidance for states and territories that receive grants from EPA to help monitor their beaches for bacterial pollution. A major goal for this revision is to encourage states to adopt a more comprehensive approach to monitoring and public notification plans by using better information and new tools. In the draft version, we incorporated key aspects of the 2012 recreational water quality criteria.

In an effort to increase protection of the public while swimming or otherwise enjoying activities in or near the water, the draft guidance proposed a new grant requirement for states to use a beach notification threshold value that would provide enhanced public health protection to beachgoers.

We asked for public comments, and since May have been working to address the comments we have received.  We will be continuing to work with state and local officials to make sure that we have an approach that is workable for them and also protects the public health and safety of beachgoers.

Gathering and Providing Information about Local Beaches

To help you plan your next trip to the beach, we’re making sure you have access to information we collect about beaches around the country. The BEACON (Beach Advisory and Closing Online Notification) is a national database that contains beach monitoring and notification data reported by states, territories, and tribes. If BEACON does not have recent water quality information, contact your state, territory, or tribe’s beach program or EPA’s regional beach contact person.

Our How’s My Waterway? app can help you find information about local waters using your mobile device.

We want you to enjoy your summer and we want your experience to be as safe as possible. Our priority is to use the best science to ensure that swimmers are adequately protected while in the water at our nation’s spectacular coastlines.
