Manufacturing, the area’s economic powerhouse, is also the reason Cowlitz County is an air pollution hotspot, data from the state, federal and private emission trackers reveal.
Industry, as a source of pollution, differs from the rest of the state, where the largest contributors to poor air quality are generally wood-burning stoves, wildfires and vehicles.
That reality highlights the longstanding tension between the county’s economic health, which depends on manufacturing jobs, and its broader environmental health, which is shaped by pollution from some of the area’s largest local employers.
“With everything, there’s going to be a trade-off,” county Commissioner Steve Rader said. “And ultimately, what we have to do is measure risk to reward.”
A lack of detailed local environmental health data and county-specific research on health impacts complicates the situation, leaving residents with only a partial picture of how the county’s economic lifeblood may — or may not — be affecting their health.
“We’re still at a place where real clear risk assessment is still kind of in its early stages,” Dr. Steven Krager, Cowlitz County’s health officer, said.
A manufacturing economy
Cowlitz County has more than twice the percentage of people working in manufacturing as Washington at large, a Daily News’ analysis of state data shows. Eighteen percent of Cowlitz’s workforce works in industry compared to 8% in other parts of Washington.
That large manufacturing footprint pays off for the county, with the sector generating about $600 million in wages alone in 2023, the most recent year data is available. That’s hundreds of millions more than the next largest sectors, government and health care.
Those wages could mean a higher quality of life for Cowlitz County.
Though state data doesn’t show what sectors county residents work in, U.S. Census data shows about 58% of county residents also work inside the county.
Less than one in five Cowlitz County residents have a college degree compared to more than one in three for the U.S. at large, census data also shows. Yet the county’s median household income is only about 10% lower.
Jobs in manufacturing may be credited for the extra boost: State employment data indicates employees working in that sector in the county made an average of $82,429 in 2023.
That means they earned more as individuals than the median household both in the county and around the country at large.
A toxic trade-off?
With roughly 1,500 employees between the two according to state data, Longview’s Smurfit Westrock and Nippon Dynawave paper mills employ the largest share of the roughly 7,400 people in Cowlitz County who work in manufacturing. Paper manufacturing workers also make more than $20,000 more than peers in manufacturing.
But while the facilities are two of the county’s biggest employers, data shows they’re also two of its biggest emitters of air pollution.
The two are in the top 10 largest industrial emitters in Washington of a dangerous microscopic pollutant known as PM 2.5, as well as nitrogen oxides and sulfur dioxides in Washington, 2023 Ecology Department data shows. The Clean Air Act requires the government to set standards and monitor these pollutants.
That pattern holds without a single exception for the previous five years, a Daily News analysis reveals.
For example, Nippon Dynawave emitted 2,161 tons of nitrogen oxides in 2023, the second-most behind Centralia’s Big Hanaford power plant. Smurfit Westrock emitted the eighth-most with 813 tons that year. And the two held their spots, with Nippon Dynawave staying in second, all five years. Smurfit Westrock flipped among the sixth, seventh and eighth positions.
The two facilities also emit hundreds of tons of volatile organic compounds into the air each year.
A spokesperson for Nippon Dynawave declined to comment. A Smurfit Westrock spokesman also declined to comment specifically but said the company is in compliance with its air quality permits.
Nippon Dynawave, which was included in a 2021 ProPublica report on U.S. air quality because it releases low levels of carcinogens into the air, has also been the second largest industrial emitter of carbon monoxide in recent years, Ecology data shows. The first again has been Centralia’s power plant.
And while carbon dioxide emissions aren’t included in the Ecology dataset, Smurfit Westrock is the only emitter that satellite imagery-based greenhouse gas-mapping service Carbon Mapper has identified in Washington. (Carbon Mapper’s scans do not cover the entirety of the state. Its three main coverage holes are around Aberdeen, as well as on the north and central Cascade Mountains.)
State officials said last year that Longview’s Smurfit Westrock plant also “likely caused” a mysterious odor that drew widespread attention as it hovered over southwest Washington last September.
No other companies in Southwest Washington released the same volume of emissions as the two mills, but the following entities released significant emissions some years:
Southwest Washington Clean Air Agency data from 2020 also shows Emerald Kalama Chemical released some volatile organic compounds into the air, including about 5 tons of toluene, an industrial solvent, that year and 2 tons of benzene.
Carbon Mapper imagery also shows the Headquarters Landfill near Castle Rock is the region’s only consistent emitter of methane. Representatives from Cowlitz County’s public works department could not immediately be reached, but the agency is working with Cowlitz PUD on a $40 million project to put that gas to work generating power.
Health risks?
So what exactly are all those pollutants, and what do they mean for Cowlitz County residents’ health?
For starters, while carbon dioxide and methane cause climate warming, they aren’t harmful to our health, said Krager, Cowlitz County’s health officer.
Instead, the most concerning pollutants in the region are ozone — which is formed when nitrogen oxides and volatile organic compounds combine in the sun — and the particulate matter known as PM 2.5, Uri Papish said. Papish is executive director of the Southwest Washington Clean Air Agency, which monitors, regulates and enforces clear air standards in the region.
“Those are where we bump up against health standards,” he said. “We meet all the health standards, but we’ll occasionally have bad air quality days where we can get over a health standard for those two pollutants.”
In fact, state air quality data shows Longview spent large chunks of the fall, winter and spring above “healthy” standards in “moderate” and occasionally in the zone known as “Unhealthy for Sensitive Groups.”
Papish said generally, industrial pollution actually contributes little to those health alerts. Instead, he said, the main drivers are woodstoves, wildfires and people driving.
But that’s not true in Cowlitz County. The most recent detailed emission source data from the state shows that Cowlitz County not only bucks the trend but strongly reverses it: Cowlitz County emitted more nitrogen oxides pollution than Clark County in 2020, despite having a population less than one-fourth the size.
The difference boils down to industrial emissions.
In Clark County, industrial nitrogen oxides emissions made up 2% of the county’s total 2020 emissions. Compare that with pollution from motor vehicles, which was 52% there. In Cowlitz County, drivers contributed 24% air pollution, while industrial-sourced pollution made up 51%. In sum, Cowlitz County emitted about 24 times more industrial nitrogen oxides emissions than Clark.
That trend extends beyond just Clark County to the state at large. Cowlitz County’s industrial nitrogen oxides emissions made up 13% of Washington’s total industrial nitrogen oxides emissions in 2020 — despite only being home to 1% of the population.
And those trends extend to industrial PM 2.5 and volatile organic compounds emissions in Cowlitz County, data shows.
And while the county mostly stays below federal standards, those emissions can cause health issues for people exposed to them, said Krager, the county’s health officer.
“Especially in places that have high, consistent levels of (nitrogen oxides), there’s higher rates of just asthma in general, and then elevated mortality and cardiovascular mortality,” he said.
The same is true for PM 2.5, he said, adding that those problems also occur with massive one-time pollution events like wildfires. Studies associate each of the three pollutants — nitrogen oxides, volatile organic compounds and PM 2.5 — with a handful of cancers.
State health data shows some of the highest rates of cardiovascular disease in Cowlitz County are near the region’s biggest industrial emitters in Longview.
But without focused research and detailed on-the-ground data, Krager cautioned there isn’t nearly enough information to say the county’s pollution is causing health issues.
Dr. Joel Kaufman, echoed that conclusion. He’s been a physician-epidemiologist at the University of Washington School of Public Health for about 25 years and is director of its Center for Exposures, Diseases, Genomics & Environment, which studies environmental health.
Kaufman said it’s hard to model how plumes of pollution act.
“If people live across the street from these things, that’s one thing,” he said. “However, if they live 2 miles upwind, it might not mean anything.”
A balancing act
“I’m pro-business, but I’m also pro-health,” county Commissioner Rader said. “The important thing to do is to really just to try to strike a balance to where we’re not sacrificing one for the other.”
For him, that balance looks like all parties communicating and local politicians not jumping to anti-business policies as a “knee-jerk reaction” unless it’s clear something is actually harming health, Rader said, which is not the case in the county right now.
“We also don’t want to go too far to the extreme,” he added, “to where we say, ‘Hey, just do what you want and pollute our air, pollute our water, and we’ll deal with it when the time comes.’”
While environmental health research is hard, Krager said, the county, state and county all have made significant advancements.
“We’ve made a lot of progress in general, just as a country, in terms of monitoring pollutants, and cleaning up our air in a lot of ways,” Krager said, “but there’s still a long ways to go.”
