Wildfires in Arizona and New Mexico plus fires in the Southeast are putting a large amount of smoke in the air. Strong winds in New Mexico and Colorado are dispersing smoke from the two large fires in New Mexico, Calf Canyon and Cooks Peak, keeping the those near surface plumes more narrow than they would be with slower wind speeds.

Numerous wildfire-related bills have been introduced in Congress

Summaries of 14 still pending

Tamarack Fire, July, 2021
Tamarack Fire, July, 2021 by Christine Tsuchida

It seems like in the last year there has been more wildfire-related legislation introduced in Congress than in previous years. It’s hard to say why, but it could be related to a growing number of megafires, more communities destroyed, and increased activism in the wildland firefighter community.

Of course simply introducing legislation accomplishes nothing if it does not become law, except perhaps providing a talking point for the politician’s next reelection campaign. A cynic might suggest that some bills are introduced and press releases issued by members of Congress with no hope or expectation that they will pass. But it is difficult to tell which are real and which are vaporware.

With that in the back of our minds, here is a partial list of 15 bills and the dates they were introduced which have not passed in this 117th United States Congress (2021-2022). Only a few have made it to the committee hearing stage, and none have progressed beyond that.

H.R. 5631Tim Hart Wildland Firefighter Classification and Pay Parity Act. October 19, 2021. (Rep. Joe Neguse). This bill has numerous provisions, including raising firefighter pay, creating a wildland firefighter job series, providing health care and mental health services to temporary and permanent wildland firefighters, housing stipends, and other items. (More details are in the Wildfire Today article from October 19, 2021.)

H.R.5010FIRE Act. August 13, 2021. (Rep. Mike Garcia) This bill directs the National Oceanic and Atmospheric Administration (NOAA), in collaboration with the U.S. weather industry and and academic partners, to establish a program within NOAA to improve wildfire forecasting and detection.

H.R.2585FIRE Act of 2021. April 1,5 2021 (Rep. Dusty Johnson) Timber salvage sales. No later than 60 days after a wildfire is contained on such lands (1) the Forest Service, to the maximum extent practicable, shall complete a survey of the lands that were impacted by such wildfire; and (2) the Department of Agriculture (USDA) shall convert the timber sales applicable to such lands that were impacted by such wildfire to salvage sales. The bill designates a categorical exclusion for forest management activities where the primary purpose of the activity is for roadside salvage activities that allow for the removal of hazard trees that are within 200 feet of a roadway center line. Activities carried out pursuant to this bill shall be subject to judicial review in the same manner as authorized hazardous fuels reduction projects. A court may not order a preliminary injunction enjoining the USDA from proceeding with timber sales authorized under this bill.

S.3092FIRE Act. October 27, 2021. (Sen. Alex Padilla) The bill would, according to Senator Padilla, update the Stafford Act that governs FEMA—which was written when the agency primarily focused on hurricanes, tornadoes, and floods—to improve FEMA’s response to wildfires, including by accounting for “melted infrastructure” and burned trees as well as allowing FEMA to pre-deploy assets during times of highest wildfire risk and red flag warnings. The bill would also ensure cultural competency for FEMA’s counseling and case management services, help to ensure relocation assistance is accessible to public infrastructure in fire prone areas, prioritize survivors’ housing needs after disasters, ensure equity of assistance for tribal communities and tribal governments, and examine ways to speed up the federal assistance process and improve the availability of fire insurance. More info.

S.1734National Prescribed Fire Act of 2021. May 20, 2021. (Sen. Ron Wyden). The bill would appropriate $300 million each to the Departments of the Interior (DOI) and Agriculture (DOA) to increase the pace and scale of controlled burns on state, county, and federally managed lands. It sets an annual target of at least one million acres treated with prescribed fire by federal agencies, but not to exceed 20 million. It requires the two departments to hire additional employees. Overtime payments for prescribed fire could be paid out of wildfire suppression accounts. More info.

S.138Wildland Firefighter Pay Act. January 28, 2021. (Sen. Dianne Feinstein.) It would raise the maximum limit on overtime pay for federal firefighters. The current limit affects higher level employees at the GS-12 and above level, and some GS-11s depending on if they are exempt from the provisions in the Fair Labor Standards Act. Under the existing provisions if they work hundreds of hours of overtime they may reach the cap after which they earn no more money. In some cases later in the fire season employees who spent a lot of time fighting fires have been told they earned too much and were forced to pay some of it back. More info.

S.1116Federal Firefighters Fairness Act of 2021. April 14, 2021 (Sen. Thomas Carper.) Establishes for federal workers certain medical conditions as presumptive illnesses. Specifically, the bill provides that (1) heart disease, lung disease, and specified cancers of federal employees employed in fire protection activities for at least 5 years are presumed to be proximately caused by such employment if the employee is diagnosed with the disease within 10 years of employment; and (2) the disability or death of the employee due to such disease is presumed to result from personal injury sustained in the performance of duty. These presumptions also apply to fire protection employees (regardless of the length of employment) who contract any communicable disease at the center of a designated pandemic or any chronic infectious disease that the Department of Labor determines is related to job-related hazards.

H.R.6336Western Wildfire Support Act of 2021. December 20, 2021. (Joe Neguse.) Establishes a program to train and certify citizens who wish to be able to volunteer to assist USDA or Interior during a wildland fire incident, and a program to award grants to eligible states or units of local government to acquire slip-on tank and pump units for a surge capacity of resources for fire suppression. It requires the Joint Fire Science Program to carry out research and development of unmanned aircraft system fire applications.

S.2419Wildfire Smoke Emergency Declaration Act of 2021. (Sen. Jeff Merkley.) This bill authorizes the President to declare a smoke emergency and provide emergency assistance to affected communities under specified circumstances. Specifically, the President, upon determining that there is, or anticipating that there will be, a significant decrease in air quality due to wildland fire smoke in one or more states, may declare a smoke emergency. The governor or other agency of a state that is or will be affected may request such a declaration. If the President declares a smoke emergency, the Federal Emergency Management Agency (FEMA) and other federal agencies may provide emergency assistance to states and local communities that are or will be affected by the emergency, including grants, equipment, supplies, and personnel and resources for establishing smoke shelters, air purifiers, and additional air monitoring sites. The Small Business Administration may provide grants to any small business concern that loses a significant amount of revenue due to wildland fire smoke in an area in which the President has declared a smoke emergency.

S.2661Smoke-Ready Communities Act of 2021. August 5, 2021. (Sen. Jeff Merkley) Provides funding for infrastructure upgrades to public buildings to filter out wildfire smoke. It would also assist with local efforts to provide health information about wildfire smoke.

S.2421Smoke Planning and Research Act. July 21, 2021. (Sen. Jeff Merkley.) It would make available each year $80 million to fund research on the public health impacts of wildfire smoke and create a grant program for local community planning relating to wildfire smoke.

H.R.4614Resilient Federal Forests Act. (Rep. Bruce Westerman) Primarily related to the logging industry, it streamlines or avoids compliance with some requirements of the National Environmental Policy Act by establishing numerous categorical exclusions for projects on National Forest System and public lands. It does away with many of the environment regulations a logging company must satisfy before a timber sale takes place.

S.48721st Century Conservation Corps Act. (Sen. Ron Wyden.) The bill would provide funds to support a natural resource management and conservation workforce and bolster wildfire prevention and preparedness. Establishes a $9 billion fund for qualified land and conservation corps to increase job training and hiring specifically for jobs in the woods, helping to restore public lands and provide jobs in a time of need. Provides an additional $3.5 billion for the U.S. Forest Service and $2 billion for the U.S. Bureau of Land Management to support science-based projects aimed at improving forest health and reducing the risk of catastrophic wildfire. Establishes a $2 billion fund to provide economic relief for outfitters and guides holding U.S. Forest Service and U.S. Department of the Interior special use permits. Provides $2 billion for the National Fire Capacity program, which helps the Forest Service implement FireWise, to prevent, mitigate, and respond to wildfire around homes and businesses on private land. Provides $2 billion for the FEMA Building Resilient Infrastructure and Communities (BRIC) program to improve resiliency for communities impacted by wildfire. Provides $6 billion for U.S. Forest Service, $6 billion for the National Park Service, and $2 billion for the Bureau of Land Management maintenance accounts to create jobs, reduce the maintenance backlog, and expand access to recreation. More information.

S.2650Wildfire Resilient Communities Act. August 5, 2021. (Sen. Jeff Merkley.)  Sets aside $30 billion for the U.S. Forest Service and the Bureau of Land Management to boost catastrophic wildfire reduction projects. Provides financial and technical assistance to at-risk communities adjacent to Federal land, including through States, to assist the at-risk communities in planning and preparing for wildfire, including cosponsoring and supporting the expansion of the Firewise USA program, the Ready, Set, Go program, and the Living with Wildfire program.

Study finds that short-term exposure to smoke from 2016 Fort McMurray wildfires in Alberta affected lung function

Equipment more sensitive than a conventional spirometer was able to detect lung damage

A study on the health of Royal Canadian Mounted Police (RCMP) officers who were deployed in Alberta, Canada in 2016 to the Horse River Fire at Fort McMurray found that their airway function was compromised in the first three months after deployment. An analysis of health data from 218 officers revealed that the small airways in their lungs underwent structural changes after they were deployed, potentially increasing their risk for respiratory diseases in the future. The median exposure duration of the officers was eight days.

“We cannot tell from our study whether it’s long-lasting damage, but we do know from other studies that if people are exposed to high levels of particulate matter in the air, they are more likely to suffer from long-lasting damage to the lungs,” said Paige Lacy, professor of medicine at the University of Alberta and former director of research for the Alberta Respiratory Centre.

The Horse River Fire caused the largest evacuation in Canadian history, with more than 80,000 people rapidly removed from the community as fires encroached on the city. Hundreds of RCMP members were sent to the community to assist with the evacuation and to secure the area in the following days. The fire burned 589,552 hectares (1.4 million acres) in 2016 and destroyed 2,400 structures. The extreme fire behavior created lightning in the pyrocumulonimbus cloud atop the smoke column that started a number of new wildfires 40 kilometers (26 miles) ahead of the main wildfire front according to a report released in June of 2017.

Horse River Fire Alberta
These two fires started at about the same time on May 1, 2016 near Fort McMurray, Alberta, Canada. On the left is the MMD-004 fire inside the city limits of Fort McMurray. The Horse River Fire, often referred to as the Fort McMurray Fire, is on the right.

Subtle changes in lung function detected
The lung-function data were gathered as part of a larger study being conducted by Synergy Respiratory and Cardiac Care, looking at the health of RCMP officers dispatched to the Fort McMurray wildfire. According to the researchers, the subtle differences in lung function that were found were not measurable using traditional lung-function tests, and could only be observed through the use of more sensitive instruments. Researchers employed both spirometry and body plethysmography testing methods.

“Small airways are potentially more vulnerable and there is no way that a spirometer (a device commonly used to measure lung function) can detect the progression of their damage over time,” said Subhabrata Moitra, first author on the study and a post-doctoral fellow in the U of A’s Division of Pulmonary Medicine. “So if we use highly sensitive instruments, we can immediately get some signals whether there are any acute yet subtle changes caused by physiological factors or occupational or environmental hazards.”

The researchers noted that because the officers only came in for testing once after being deployed, they were not able to observe potential recovery of lung function or measure long-term damage.

The authors of the study pointed out the importance of having a health-surveillance program in place so responders who are exposed to such hazards can have their health monitored.

Survey finds that firefighters also complained of respiratory issues
A survey found that some firefighters who fought the fire at Fort McMurray also battled respiratory and mental health issues.

Below is an excerpt from a 2017 CBC news article:

The University of Alberta study surveyed 355 firefighters and found a “very large proportion” of them complained of respiratory issues including coughing, breathlessness, wheezing and chest tightness in the immediate aftermath of the fire.

“When we saw them later, probably about one in five of those still had problems with their chests that they felt had been caused or made worse by the fire,” said Nicola Cherry, the epidemiologist leading the study.

And they’re battling more than just physical ailments — mental-health issues affect one in six of study participants.

“When we collected this information, it was early days and people may develop bigger issues as time goes forward,” Cherry said.

Our Take
It is likely that wildland firefighters are routinely exposed to far higher concentrations of smoke and for longer periods of time than the RCMP officers at Fort McMurray. It is important that agencies who employ wildland firefighters establish a health-surveillance program that includes lung function tests using methods such as body plethysmography that are much more sensitive than a conventional spirometer.

Researchers find that wildfire smoke poses neurological hazards

Inhaled microscopic particles from wood smoke can work their way into the bloodstream and reach the brain, putting people at risk for premature aging and various forms of dementia, depression, and even psychosis

The research outlined below by the University of New Mexico Health Sciences Center is further evidence of the importance of smoke management. Land managers, agency administrators, and incident management teams need to constantly consider methods of reducing smoke exposure to firefighters and the downwind population when planning, conducting, or suppressing wildfires and prescribed burns.


Woodsmoke from massive wildfires burning in California shrouded much of the West last summer, making it harder for people suffering from respiratory illnesses to breathe.

Those respiratory consequences can be dangerous — even life-threatening — but Matthew Campen, PhD, a professor in The University of New Mexico College of Pharmacy, sees another hazard hidden in the smoke.

In research published online this week in the journal Toxicological Sciences, Campen and his colleagues report that inhaled microscopic particles from woodsmoke work their way into the bloodstream and reach the brain, and may put people at risk for neurological problems ranging from premature aging and various forms of dementia to depression and even psychosis.

“These are fires that are coming through small towns and they’re burning up cars and houses,” Campen says. Microplastics and metallic particles of iron, aluminum and magnesium are lofted into the sky, sometimes traveling thousands of miles.

In the research study conducted last year at Laguna Pueblo, 41 miles west of Albuquerque and roughly 600 miles from the source of wildland fires, Campen and his team found that mice exposed to smoke-laden air for nearly three weeks under closely monitored conditions showed age-related changes in their brain tissue.

The findings highlight the hidden dangers of woodsmoke that might not be dense enough to trigger respiratory symptoms, Campen says.

As smoke rises higher in the atmosphere heavier particles fall out, he says. “It’s only these really small ultra-fine particles that travel a thousand miles to where we are. They’re more dangerous because the small particles get deeper into your lung and your lung has a harder time removing them as a result.”

When the particles burrow into lung tissue, it triggers the release of inflammatory immune molecules into the bloodstream, which carries them into the brain, where they start to degrade the blood-brain barrier, Campen says. That causes the brain’s own immune protection to kick in.

“It looks like there’s a breakdown of the blood-brain barrier that’s mild, but it still triggers a response from the protective cells in the brain — astrocytes and microglia — to sheathe it off and protect the rest of the brain from the factors in the blood,” he says.

“Normally the microglia are supposed to be doing other things, like helping with learning and memory,” Campen adds. The researchers found neurons showed metabolic changes suggesting that wildfire smoke exposure may add to the burden of aging-related impairments.

The research team included colleagues from the College of Pharmacy and the UNM Departments of Neurosciences, Geography & Environmental Studies, and Earth and Planetary Sciences, as well as researchers at Arizona State University, Michigan State University and Virginia Commonwealth University.

Residents along the Southern California coast are seeing the effects of the Alisal Fire in the air they are breathing. On Thursday the South Coast Air Quality Management District issued a special air quality advisory for smoke that will be worsening during the afternoon.

Heavier concentrations of the smoke are expected to move into the counties of Orange, Riverside, San Bernardino, and L.A. Thursday afternoon and evening.

The Alisal Fire has burned more than 16,000 acres 19 miles west of Santa Barbara.

Smoke from California wildfires increases doctor visits and blocks sun from crops

Study shows N95 masks can reduce hospital visits for smoke inhalation by up to 40 percent

Recent articles on MSN.com pointed out three different wildfire smoke related issues.

Smoke in California’s Central Valley increased doctor visits (Oct. 3 2021)

Dr. Praveen Buddiga, a local allergy and immunology specialist, says he saw an increase in patient visits on Friday due to the smoke sitting in the Valley.

“Today I’ve been seeing a lot of patients with cough, congestion, difficulty breathing and this is directly related to the air,” said Dr. Buddiga.

Dr. Buddiga said many of his patients have difficulty breathing, which is not surprising considering the smoke is even visible in satellite images taken from space.

Some masks can protect against wildfire smoke (Sept. 30, 2021)

Researchers found that N95 masks often used for protection from COVID-19, are effective in reducing the inhalation of wildfire smoke particles, and could reduce hospital visits for wildfire smoke inhalation by up to 40 percent. They found that surgical masks, primarily designed to keep sneeze and cough droplets from emerging in the air, do not not protect the wearer against a dangerous environment. Cloth masks used alone are also ineffective. While surgical masks by themselves were ineffective, combining them with a cloth mask to compensate for the surgical mask’s loose fit was about as effective as an N95 as long as the seal around mouth and nose was good.

Wildfire smoke is blocking Central Valley crops from the sun (Oct. 6, 2021)

…This smoke could cause some damage to the raisin and almond crops that are still drying out in the fields.

“Those two crops specifically need mother nature, as in the sun, to dry those crops out in the field, and that drying time is essentially eliminated right now with the smoke layer that we have,” said Ryan Jacobsen, CEO of the Fresno County Farm Bureau, “We’re just not seeing it, we aren’t seeing any drying taking place and that becomes very problematic especially for raisins because if they don’t dry they’re going to sit there and rot in the field. So, we’re hoping that this weather change we’re going to see take place in the next couple of days hopefully blows this smoke out of there and returns the sun to help us finish off this crop year.”

Jacobsen says the Farm Bureau’s other priority is the health and safety of farmworkers. For their protection, the bureau has been providing N95 respirators to agricultural employers.
