Let’s talk about elevated temperatures in landfills 🌡️ As the microorganisms in a municipal solid waste landfill break down waste, the generation of heat is normal. But abnormal chemical reactions within the waste mass can cause landfill temperatures to rise which can cause changes in landfill gas composition, noxious odors, rapid and severe waste settlement, leachate seeps and outbreaks, and generate strong leachate, all of which add to operator costs for facility management and can impact human health. If you support the operation, management, or provide oversight of municipal landfills, please join our next #EPAtools Webinar: Elevated Temperature Landfills: Case Studies, Indicators, and Knowledge Gaps on Wednesday, July 16, 2025, from 3-4 pm ET. You’ll hear about various strategies used at elevated temperature landfills to manage or control the sub-surface reactions, the indicators or symptoms operators and regulators should be looking for and identify some key questions that remain unanswered.

🦠 Foreign animal diseases like African Swine Fever and Highly Pathogenic Avian Influenza can be devastating to our food and agricultural sectors. 🐾 To prevent environmental contamination and spread of disease, emergency managers and responders need to effectively manage animal mortalities during an outbreak. Learn about methods that could be used for carcass disposal. 🗓️ July 9 at 2 PM ET Register Now: https://xmrrwallet.com/cmx.pspgv.io/6043B1wX

Responding to disasters is difficult enough, but adding potential impacts from rainstorms can exacerbate those response and recovery efforts. Stormwater can transport pollutants, such as heavy metals, pathogens, and nutrients, which threaten the quality of rivers, lakes, and oceans. But we have a tool to support emergency personnel and stormwater operators! Watch this on-demand webinar to learn how to use EPA's Storm Water Management Model (SWMM) to track the fate and transport of contaminants and preview soon-to-be released Stormwater Emergency Response Tool and Optimizer which leverages SWMM to plan sensor detection networks before an emergency strikes. https://xmrrwallet.com/cmx.pspgv.io/6048B13s

It's Hurricane Season and the damaging winds and heavy rains of a hurricane often leave destruction in their wake. Communities working to get back on their feet face the challenge of what to do with all that contaminated floodwater and millions of tons of waste and debris left behind. To help manage this, EPA and partners developed a suite of tools, which includes the Incident Waste Assessment & Tonnage Estimator (I-WASTE): https://xmrrwallet.com/cmx.pspgv.io/6043BDs1 and the Municipal Solid Waste Decision Support Tool (MSW DST): https://xmrrwallet.com/cmx.pspgv.io/6044BDsG Explore the links to learn how these tools can assist urban and rural communities in developing appropriate strategies for their waste management planning and emergency response for hurricanes and other disasters.

Join us for this month’s EPA Tools & Resources Training Webinar on June 5, 3PM ET on “Wildfire Smoke Air Monitoring Response Technology and AirNow Fire and Smoke Map.” #Wildfires are a major source of poor air quality across the U.S. This webinar will showcase two tools to help state, local, and tribal air quality and public health agencies in assisting the public in getting and interpreting near real-time air quality information during wildfires and smoke events, along with steps they can take to protect their health. The Wildfire Smoke Air Monitoring Response Technology (WSMART) loan program provides emerging technologies to air quality emergency responders. The AirNow Fire and Smoke Map, developed in partnership with the U.S. Forest Service, provides the public with information on fire locations, smoke plumes, air quality, Smoke Outlooks for large U.S. wildfires, and protective actions to take.

Effective rulemaking requires public input. Have a point of view about EPA's Waters of the United States (WOTUS) definition? We are heading to Utah to hear it. Waters of the United States (WOTUS) is an issue of great national importance as it establishes the geographic scope of federal jurisdiction under the Clean Water Act. EPA is reviewing the definition to ensure it follows the law, reduces red tape, cuts overall permitting costs, and lowers the cost of doing business while protecting water resources. Join EPA and Army for a listening session open to the public in Salt Lake City or join us online. Register here: https://xmrrwallet.com/cmx.pspgv.io/60474DH

Join our May 21st, 3pm ET webinar to learn how #EPAers are filling knowledge gaps on smoke infiltration and mitigation indoors. Our researchers worked with community partners in Montana and California on a multifaceted study examining #WildfireSmoke indoor air quality impacts in public spaces and innovative approaches to reduce wildfire smoke indoors.

This Great Lakes Awareness Day we’re highlighting the #EPAresearch that supports the National Aquatic Research Surveys (NARS) in the Great Lakes: https://xmrrwallet.com/cmx.pspgv.io/6047xac The NARS is a collaborative effort between EPA and local states and tribes. EPA scientists work to monitor invasive species and water quality every five years as a requirement of the Clean Water Act. This information ensures that decision makers have the most up-to-date information about conditions in the Great Lakes and how they have changed over time.

Our environmental and conservation stakeholders are critical to EPA’s mission. Together we can reduce red tape, cut overall permitting costs, and lower the cost of doing business in communities nationwide. Join us Thursday, May 1, at 1:30 pm ET to hear or join the discussion about EPA’s Waters of the U.S., or WOTUS definition. Environmental and conservation stakeholders can register to attend online at this link! https://xmrrwallet.com/cmx.pspgv.io/6048aRM

Our partners are our greatest asset. That’s why we are engaging our industry and agricultural stakeholders on EPA’s Waters of the U.S. (WOTUS) definition. Together we can reduce red tape, cut permitting costs, and lower the cost of doing business in communities nationwide. #PoweringtheGreatAmericanComeback #WOTUS Join us on Thursday, May 1, at 9:30 am ET to have your voice heard or listen to the comments.
