EPA wants to develop low-cost sensor system to monitor smoke

EPA wildfire smoke sensor challengeThe Environmental Protection Agency has announced an initiative to develop a new low-cost system that could monitor air quality affected by smoke from wildland fires. The existing hardware is large, cumbersome, and expensive, thereby limiting the number of monitoring stations and the data that is available to help officials provide appropriate strategies to minimize smoke exposure.

Below is an excerpt from the EPA’s announcement about what they call the Wildland Fire Sensors Challenge. The three graphics were part of the agency’s news release.

Today, emerging technologies – including miniaturized direct-reading sensors, compact/powerful microprocessors, and wireless data communications – offer the opportunity to develop new systems to quickly gather and communicate air pollution data.EPA wildfire smoke sensor challenge

Wild fires are increasingly common events that produce significant air pollution, posing health risks to first responders, residents in nearby areas, and downwind communities. Also, wild fires are increasing in frequency and intensity, and the fire season is growing longer.  Prescribed fires, which are used to manage ecosystems or reduce risk of wild fires, are typically managed to minimize downwind impacts on populated areas; however, people in close proximity may still be exposed to smoke.  The description “wildland fires” refers to both wild and prescribed fires.

This challenge seeks a field-ready prototype system capable of measuring constituents of smoke, including particulates, carbon monoxide, ozone, and carbon dioxide, over the wide range of levels expected during wildland fires. The prototype system should be accurate, light-weight, easy to operate, and capable of wireless data transmission, so that first responders and nearby communities have access to timely information about local air quality conditions during wildland fire events.

EPA cooperators

The EPA is partnering with several agencies to develop this equipment: Forest Service, National Park Service, National Oceanic and Atmospheric Administration, National Aeronautics and Space Administration, and Centers for Disease Control and Prevention.

However, with the current Administration’s intended massive cutbacks to the EPA and even scattered calls to eliminate the agency, finding the money and staff to bring this idea to fruition is anything but a slam dunk.

New EPA rule could benefit prescribed fire

Below is an excerpt from an article at the Rural County Representatives of California website.


“The U.S. Environmental Protection Agency has released its draft amendments to the Exceptional Events Rule, and have included as a companion a draft Guidance on Preparing Exceptional Events Demonstrations for Wildfire Events that May Influence Ozone Concentrations (Guidance).  The Guidance provides methodology for air agencies to differentiate wildfire events from other planned fire events, such as prescribed burns, and to make the preparation and demonstration for these events more efficient.  

The Guidance has been released in response to concerns by stakeholders, including RCRC, that the National Ambient Air Quality Standards for ozone finalized earlier this year will essentially eliminate the use of prescribed burning as a method of fuels treatment in forest management projects.  The Exceptional Events Rule (Rule) allows for local and state air agencies to demonstrate events that they feel should be excluded from air quality data in their regulatory decisions.  Comments on the Rule amendments and draft Guidance are due by January 19, 2016, and can be accessed here.”

Smoke from wildfires spreads further east

Smoke from wildfires in the Northwest and California is causing “unhealthy” air quality in much of Washington, Oregon, and Idaho. It is also having an effect in the upper mid-west, the center of the United States, and the provinces of Ontario and Quebec.

Much of the blame for “unhealthy” air quality in the northwest can be blamed on smoke from wildfires.
