Ethanol consistency sought
EPA is proposing to apply the
same air permitting requirements for facilities that produce ethanol
for fuel or human consumption. Ethanol, a clean-burning renewable
fuel, can be used to meet the requirements of the Renewable Fuels
Standard Program, which is designed to reduce dependence on foreign
oil by doubling the use of vehicle fuels from American crops by
Ethanol is produced at corn milling
facilities for use as fuel or human consumption. While the processes
are similar, these facilities are currently treated differently
under Clean Air Act permitting programs. EPA’s proposal
would provide equal treatment for corn milling facilities, regardless
of whether they produce ethanol for fuel or human consumption.
Currently, corn milling facilities
that produce fuel and emit less than 100 tons per year of air
pollutants are not subject to the Prevention of Significant Deterioration
(PSD) permitting program. Conversely, corn milling facilities
that produce products for human consumption do not trigger PSD
until they emit more than 250 tons per year.
The proposal would establish
the same emissions limits under the PSD program – 250 tons
per year – regardless of whether the ethanol end product
is used for fuel or human consumption. The thresholds for the
New Source Review and Title V permitting programs would remain
at current levels, which vary from 10 to 100 tons per year depending
on the area in which the facility is located.
EPA will accept comment on this
proposal for 60 days following publication in the Federal Register.
