FRIDAY, June 15 (HealthDay News) — The U.S. Environmental
Protection Agency (EPA) is proposing new standards to regulate fine
particle air pollution, including soot, officials announced Friday.
The new standards will call for a reduction in fine particle pollution
from the current 15 micrograms per cubic meter of air to 12 to 13
micrograms.
The EPA’s move comes in response to a court order that required the
agency to update its regulations based on the best science available.
The agency is calling the new standards a victory for public
health.
“As a result of these rules, we will be saving hundreds of thousands of
lives and prevent significant amounts of health consequences including
premature death,” Gina McCarthy, assistant administrator in EPA’s Office
of Air and Radiation, said during a press conference Friday.
“The good news about today’s action is that we are already on the path
for 99 percent of U.S. counties to meet the standards without the need
for additional state or local action,” she added.
The new standard will have to be met by 2020 and will affect diesel
engines, power plants and industrial plants among other producers of fine
particle pollution, McCarthy said.
Fine particle pollution can reach deep into the lungs and has been tied
to premature death, heart attacks and strokes.
In addition soot particles, known to scientists as “PM2.5,” also can
cause bronchitis and worsen childhood asthma, the agency notes.
This new standard reflects the findings of many studies that show
harmful health effects from even low concentrations of fine particle
pollution, the agency says.
This reduction in fine particle pollution is expected to have health
benefits as well as financial benefits by cutting health care costs, the
agency contends.
“Depending on the final standard, estimated benefits will range from
$88 million a year, with estimated costs of implementation as low as $2.9
million, to $5.9 billion in annual benefits with a cost of $69 million —
a return ranging from $30 to $86 for every dollar invested in pollution
control,” the EPA projects.
The proposed standard is open for public comment for the next 63 days
with the final standard being issued by Dec. 14.
Commenting on the EPA’s announcement. John Walke, clean air director at
the Natural Resources Defense Council, said in statement that, “updating
these standards will protect us from the tiniest particles that can cause
the biggest health problems.”
“By limiting the smoke, soot, metals and other pollution our lungs and
hearts absorb, EPA is protecting all of us from asthma attacks, lung
cancer, heart disease and premature deaths,” he said.
“This a tremendous win for our health and the environment that could
only be achieved by following the best science and upholding the Clean Air
Act,” Walke added.
