Are PM2.5 Regulations Appropriate?

Turbomachinery magazine has demonstrated there is a need to revise the EPA regulations concerning ultra-small particulate matter defined as PM 2.5, or matter that is less than 2.5 micrometers in size. A particle that is 2.5 micrometers in size is 1/30 the diameter of a human hair.

The magazine established that less than 3% of the particulate matter, 2.5 micrometers or smaller, comes from utility power plants.

Chart from Turbomachinery magazine.

As the chart shows, the vast majority of 2.5 particulate matter comes from a wide variety of sources including industrial, waste disposal, highway and off-highway vehicles, and a myriad of other sources. Less than 3% are produced by the utility industry.

Regulations targeting the utility industry make no sense. 

The regulations were established by the EPA during its war on coal.

Perhaps even more important, the science used by the EPA to justify the establishment of the regulations was suspect.

Quoting from Turbomachinery, “The Obama administration estimated that the measure would prevent 4,700 heart attacks and 130,000 asthma attacks, as well as 11,000 premature deaths by also eliminating fine particulate matter linked to those ailments.”

There is solid evidence that PM 2.5 is not the villain championed by the EPA.

Here is a quote from The National Center for Biotechnology Information describing studies that contradict the EPA’s findings:

“Enstrom does a reanalysis of a large national cohort study and, unlike the original authors, finds no effect of small particulate matter, PM2.5, on total mortality … Young points to 21 studies, including Enstrom, that find no evidence of an association PM2.5 with mortality.”

Quoting from an article published June, 2015, “A new study by Stanley Young, Ph.D, proves they do not [kill people]. Another scientist, Dr. Enstrom, has pointed out that the average U.S. adult inhales about 1 teaspoon of invisible PM 2.5 in 80 years.”

There is compelling evidence that:

  1. PM 2.5 are not the threat originally promoted by the EPA 
  2. EPA regulations target the utility industry that produces less than 3% of the 2.5 micrometer particulate matter, thereby making the regulations ineffective.

Existing PM 2.5 regulations targeting the utility industry are likely inappropriate and ineffective.

  1. Thanks for the informative article with data to prove the point.
    Interesting 75% of the particles in question are from miscellaneous and wildfire sources while less than 3% are from electric power plants.
    This pretty much confirms the lack of science under the Obama EPA and the need to correct their numerous errors mostly for political purposes.
    Also interesting to note that the 15% from wildfires is a source that was also ignored or neglected especially in California for lack of proper forest management.
