I notice no one here has tried to find the dangerous dose level of Mercury which is found naturally in nature, from
HERE is this statement that can't be ignored:
"Emissions from Power Plants
Since mercury occurs naturally in coal and other fossil fuels, when people burn these fuels for energy, the mercury becomes airborne and goes into the atmosphere. In the United States, power plants that burn coal to create electricity account for about 42 percent of all manmade mercury emissions (
Source: 2014 National Emissions Inventory, version 1, Technical Support Document (December 2016)(PDF)(discussion starts on page 2-25 of the PDF document). "
Coupled with these from the
FIRST LINK at post 1,
"The EPA says it is keeping the 2012 restrictions in place for now, in large part because utilities have already spent billions to comply with them."
and,
"Even though the EPA's mercury standards have faced court challenges, utilities spent more than $18 billion to comply with the requirements.
In a letter to the EPA last summer, utilities and regulatory and labor groups said mercury emissions had been reduced by nearly 90 percent over the past decade.
In that letter they also asked the Trump administration's EPA to leave the existing standards in place.
Since many regulators have included the equipment costs in utility rates, some worry that no longer requiring the limits could leave customers paying for the pollution controls without getting cleaner air. That's because it also costs money to continue operating that equipment."
From the
SECOND LINK at post 1:
"
The Mercury and Air Toxics Standards, or MATS as it's called, went into effect in 2015 under the Obama administration. At the time, the cost to industry for installing the technology to reduce mercury emissions was estimated at nearly $10 billion, while the health benefits were calculated at only several million dollars.
But the Obama administration also factored in "co-benefits" the rule would produce, such as reductions in soot and nitrogen oxide,
raising the maximum benefits to as much as $90 billion through reduced premature deaths, sick days and hospital visits."
I have yet to see credible disputing response to this suggested benefit of the CURRENT regulations in place that industry already complied with.
At this time relaxing the mercury emission rules makes no sense since the cost is already factored in and the money spent to comply with the 2012 regulations.
