Re: Docket ID No. EPA-HQ-OAR-2013-0495-2338,
Standards of Performance for Greenhouse Gas Emissions for New Stationary 
Sources: Electric Utility Generating Units

Dear Administrator McCarthy:

This letter and its attachment are comments submitted for the proposed rulemaking 
regarding Standards of Performance for Greenhouse Gas Emissions for New Stationary 
Sources: Electric Utility Generating Units. In its “Summary,” EPA states: “This action will 
amend the new source performance standards (NSPS) for electric generating units 
(EGUs) and will establish the first NSPS for greenhouse gas (GHG) emissions. The rule 
will establish C02 emission standards for certain new and reconstructed fossil fuel-fired 
electric generating units.”

Please consider these “comments” in the development and selection of the final rule.

As you undoubtedly know, OMS is currently in the process of reviewing comments on the document known as “Technical Support Document: - Technical 
Update of the Social Cost of Carbon for Regulatory Impact Analysis - Under Executive 
Order 12866” ("TSO"). The TSD is designed and intended to become the basis for 
ongoing restriction on the use of carbon-based energy in the United States, whether 
through regulatory or legislative action.

I submitted one of the many letters of comment to OMS as part of its review process: A 
copy of my letter is attached.  My letter points to several obvious aspects ofthe TSD that make it so 
clearly flawed as to call into question the fundamental honesty and ethics of this entire 
regulatory effort.

Most notably:

The TSD purports to rely on IPCC work as a basis for a supposed “sensitivity” of 
climate to increasing atmospheric C02, but fails to mention that the most recent 
IPCC report completely undermines any basis for determining climate sensitivity 
with the following statement: “No best estimate for equilibrium climate sensitivity 
can now be given because of a lack of agreement on values across assessed 
lines of evidence and studies.” This means that the IPCC admits that it does not 
have a credible mean, mode or median value of the equilibrium climate 
sensitivity parameter. In the mathematics of Decision Theory, this situation is 
called Complete Ignorance Uncertainty.

The TSD fails to note that EPA’s so-called “Endangerment Finding” of 2009 with 
regard to atmospheric C02 has. been invalidated by the failure of real world data 
to support each of the three “lines of evidence” on which EPA purported to rely in 
reaching its Finding.

The TSD calculates the supposed “social cost of carbon” by focusing almost 
entirely on supposed worldwide negative consequences of increasing C02; while 
completely ignoring and not even attempting to evaluate - the obvious major 
positives of carbon energy usage and increasing C02, such as making 
inexpensive energy accessible to the poor and increasing agricultural productivity.

In its current state, the TSD can only be described as fundamentally dishonest and 
unethical. I strongly urge you to rethink how such a completely dishonest and unethical 
effort, with potential enormous costs and consequences for the American people and 
the economy, has come to advance so far in the government’s processes. Clearly 
proposing a NSPS for greenhouse gas emissions makes absolutely no sense 
whatsoever in that such standard would then be based on both a grossly flawed 
Endangerment Finding and fatally flawed Social Cost of Carbon.

Please consider this letter in the development and selection of the final rule. 
Thank you for your consideration.
