Buying Advice Tier V emission standards soon for new diesel engine tractors?

tell that to my 55 year old nurse wife that died of cancer.
your statement is remarkably insensitive and adds nothing to the discussion

They’re trying to make a point although it’s inaccurate because they are ill-informed. Cancer, regardless of the type, isn’t just for “old” people. Sorry for your loss.

Tier V emission standards soon for new diesel engine tractors?

DPF exemption for <25-horsepower diesel engine tractors to expire?

EPA announces new air quality standards for particulate matter, citing health risks.​

The Environmental Protection Agency announced a new rule on Wednesday to significantly reduce the level of air pollution known as particulate matter (PM) by updating the national air-quality standards, citing negative health impacts of PM exposure.

While the rule is being praised by environmental and health groups, some industry groups have signaled that it could pose a political challenge for President Joe ***** this year as they claim it will hamper American manufacturing and eliminate jobs.

“Today's action is a critical step forward that will better protect workers, families and communities from the dangerous and costly impacts of fine particle pollution,” EPA Administrator Michael Regan told reporters.

“The science is clear, soot pollution is one of the most dangerous forms of air pollution and it's linked to a range of serious and potentially deadly illnesses, including asthma and heart attacks.”

Particulate matter is made up of microscopic solid particles such as dirt, soot or smoke and liquid droplets in the air that are small enough to be inhaled. Those small particles can get into the lungs or bloodstream and contribute to health problems like asthma, respiratory symptoms, heart attacks, or premature death in people with heart or lung problems, according to the EPA.


This type of pollution comes from a variety of sources including power plants, cars, and construction sites. Wildfire smoke is also a significant source of particulate matter pollution.
“And often that is a product of triggering heart attack, cardiopulmonary events or triggering asthma attacks that are fatal,” Simms said.

Regan said the updated standard will prevent up to 4,500 premature deaths and 290,000 lost workdays in the year 2032. On that same timeline, ***** administration officials also say the new standard will yield up to $46 billion in net health benefits.

“The impact of this pollution oftentimes disproportionately affects our most vulnerable communities, including low-income communities, communities of color, children, older adults and those who struggle with heart or lung conditions,” Regan said.

“There are both things that you can calculate numerically about what are the impacts [of PM pollution] and how many deaths and how many hospitalizations, but there also are really important kinds of impacts that are hard to quantify," he added.

The previous annual standard for particulate matter was 12 micrograms per cubic meter of air. Under this new rule, the EPA is lowering the annual standard to 9 micrograms per cubic meter.

The updated rules do not revise the 24-hour standard which is meant to account for short-term spikes in pollution. That will remain at 35 micrograms per cubic meter.
President and CEO of the American Lung Association Harold Wimmer called the update “a step forward for public health,” but noted that the standards fall short of what his organization and others called for.


“While the stronger annual particle pollution standard will mean fewer asthma attacks, heart attacks, strokes and deaths, it is disappointing that EPA did not follow the strong science-based recommendations of the Clean Air Scientific Advisory Committee and the health community to also revise the 24-hour standard to more fully protect public health,” Wimmer added.
Industry groups like the American Forest & Paper Association, American Wood Council and the group’s member company CEOs sent a letter to the White House in October expressing their opposition to the now finalized rule, saying the move, “threatens U.S. competitiveness and modernization projects in the U.S. paper and wood products industry and in other manufacturing sectors across our country.”

“This would severely undermine President *****’s promise to grow and reshore U.S. manufacturing jobs, and ultimately make American manufacturing less competitive,” the letter said. “It also would harm an industry that has been recognized as an important contributor to achieving the Administration’s carbon reduction goals, including in future procurement for federal buildings.”

Simms, who has worked in this space for 25 years, told ABC News these industry outcries aren’t new.

“I've been doing this work for 25 years in a variety of different capacities,” Simms said. “And I can say that every time that an agency like EPA has taken steps to protect people and to reduce pollution, I see this same playbook start to get utilized, which is ‘the sky is falling.’ ‘If we protect people this way, we're going to destroy business and we're going to undermine the economy.’ And there's really good data to show that that's just not true.”

Look at airports from a distance of about 10 miles and you can see a large cigar shape of smog enveloping the airport.
Although we all support clean air but lets be reasonable and realistic. Epa attacks those targets who can’t fight back.

Whatever. I do my part in producing particulate emissions with both my pre 4 tractors and my 1997 F350 diesel pickup truck that is chipped up. Both my tractors will blow black smoke when worked and so will my pickup truck and I won't have it any other way. Like my dad always told me... he said, Son, if there is no smoke, there is no fire and no fire equals no power' My tactors and my truck all smoke when worked. Pizz on the EPA. So does my Western Star Class 8 road tractor with it's 3406 NZ Caterpillar.

Sounds like if all your diesels are smoking, then they are all poorly tuned

Excess fuel leads to high egts

EPA is busy "fixing" polluting engines. Yet they say nothing about the rubber dust from tires as you drive down the highway, heating our homes with wood now requires a catalytic converter, they seem of little concern for private jet pollution, or for that matter even commercial jet pollution. They seem not concerned at all about so many other types of particle emmissions.
Guess the want us to go all electric so the electric generation and mining of the precious minerals used in batteries can keep on polluting. They seem to have a strong desire to eliminate all fossil fuel energy and the engines that us them.
Glad I don' have a lot of years left, but I greatly fear for my children and grandchildren.

You know, most of the people that die with heart disease and cancer are our elderly population, you know, and we all will probably die with something sooner or later.

We ‘elders’ have lived through lead based paint, no seatbelts, coal burners, no emissions standards, and yes, many of us are sick, dying or have passed away. You are fortunate to have greater protections and awareness then we had.

Many changes have been beneficial regardless of the political or economic views shared in this category. If you’re fortunate, you may become one of the very people you have spoken of, and will perhaps have a different opinion on improvements in the standards of living as introduced by the EPA and similar organizations.

People keep bring up airplanes.

Look at the old b-52 or an e-3 with the old j 35? Engines. You see a black cloud long before you see the plane

Versus a modern re engined KC-135

There have been big improvements in jets.

High bypass turbofans are much more fuel efficient than engines of the past. Hell, now we have recently begun using geared turbofans to spin the N1 even faster at the same N2 rotation speed. They are extremely high bypass fans.

Also, there is development of hybrid and electric commercial aircraft.

If you aren’t in the industry, using the equipment, you just don’t know much about it. Even if you are well versed in Kubota and Deere

I remember Dr. Elders' tenure. Quite controversial as she was speaking out on public policy that hurt our children, hurt our elders, and stymied social progress. The people who blocked her outspoken (and clearly based in science and statistics, but was NOT for our country's public consumption) were searching for their own sound bites without addressing the issues she raised.
I'll start with the last part of her quote - and that is probably one of the most bewildering - that everyone is going to

die with something sooner or later.

Not that anyone has just kept living!

Particulate matter in the 5 PM (in medicine, we consider the size, and use the PM10 an arbitrary standard for lung infiltration and one of many cause of COPD. PM10 means the particulates are 10 microns or less. Farmers have a disease named well before COPD became a Post WWII issue - Farmer's Lung. It probably first was coined during the dust bowl days. Since we can't clean India's particluates, or Turkey's, or Russia's, or any other country, we should watch our own contributions to the increase in lung disease.

Cigarettes were the cause of many of the dark streaked lungs I have seen removed in the post TB days when I assisted in surgery. With the decline in US smoking, lungs have gotten "cleaner looking", but microparticulates from all forms of soot and friction-induced tire wear (Steel belted radials reduced tire flexion enough that the even smaller microparticulates are now found in the air sacs, not just the bronchioles), and especially after 9/11 we have seen a rise in chronic lung disease.

These EPA measures are not going to remove "Farmer's Lung" from medical lexicon, yet the statistics do show that the increased microparticulate load affects long term health, and some people - asthmatics, chronic inflammatory diseased folks, and over-stressed sleep deprived folks can suffer from inflammatory triggers that yield coughing fits that seem to never end to sudden cardiac arrest.

These tighter EPA standards are not going to improve lung health in the USA very much - if farmers won't wear microparticulate respirators to improve their chances of living into their 90's, then they are going to breath dust, grinding and mowing detritus, irritating volatiles, and wear out their lungs. I can't count the people I've seen die in ICUs on ventilators whose lungs just couldn't work anymore - not after SARS-CoV-2. But I have seen old Farmers gasping for breath with severe COPD who also smoked since their service in the war - it is not a good way to go. Statistically, young children around factories (especially refineries) and National Highways do have higher rates of asthma but not as many die of the disease while growing up, they usually make it to their 20-30's before they become regulars in the ICU's. Not a huge number of disabled asthmatics, but too many for me to ignore.

Oh - Jocelyn did help shine a light on the crisis when the uneducated right wingers were stating that homosexuality was <1% of the population. Turns out even after the multiple HIV deaths, homosexuality is somewhere in the 3-6% of population. That percentage is across the board, across the workplace, and across the religious affiliations. She was lambasted for so much, and rightfully so as she was way too outspoken to helpfully move public health policy. But when America was denying any significant alternate lifestyle groups, she was showing statistics that didn't agree with their (our) worldview. For all her bluster, it made medicine start analyzing the statistics and helped kickstart the anti-viral and retro-viral innovation.

I'm retired from medicine for now, if the system gets further strained I may be back part-time, but I am sick of watching people die from cardiac and pulmonary diseases!
