SUBJECT: 2010 Clean Air Interstate Rule (CAIR) Allowances from New Unit Set-aside for
North Carolina Electric Membership Corporation (NCEMC)
NCEMC —Anson Plant, Facility ID 0400050, Air Quality Permit No. 09492
Lilesville, Anson County,North Carolina
NCEMC—Hamlet Plant, Facility ID 7700082, Air Quality Permit No. 09488
Hamlet, Richmond County, North Carolina
Dear Mr. Ryan:
Your letter of January 29, 2010 to Michael Abraczinskas, requested 2010 CAIR NOx allowances
for NCEMC Anson Plant and NCEMC Hamlet Plant. We have determined the facilities are
considered new units under 40 CFR 96.142, CAIR NOx allowance allocations and 40 CPR 96.342,
CAA?NOx Ozone Season allowance allocations. Paragraph (c)(3) of either regulation allows the
CAIR designated representative to request control period CAIR NOx allowances based on the
amount of NOx emissions during the calendar year immediately preceding the control period.
Since the 2009 annual NOx emissions from the Anson Plant were 63 tons, which included 54 tons
emitted during the ozone season (May 1 through September 30), the facility's approved 2010
annual NOx allocation is 63 tons which includes 54 tons allocated for the ozone season. Likewise,
since the 2009 annual NOx emissions from the Hamlet Plant were 16 tons, which included 2 tons
emitted during the ozone season, the facility's approved 2010 annual NOx allocation is 16 tons
which includes 2 tons allocated for the ozone season.
The Division of Air Quality(DAQ) will issue these allowances from North Carolina's new unit
set-aside account through the US Environmental Protection Agency's (EPA) Clean Air Markets
Division (CAMD). Should these units emit less than their allocated quantities, any remaining
allowances may be banked, traded, or sold. Any subsequent allocation request will be limited to

the actual emission level. Should the combined total actual amount of NOx emissions from these
units exceed their combined allocation, you must obtain sufficient allowances to cover that
difference from the cap and trade market operated by CAMD or from banked allowances that you
are holding.
Until DAQ completes a periodic reallocation per 15A NCAC 02D .2413, you must submit an
annual allocation request.North Carolina's NOx allocations for the requested year must be based
upon the previous year's actual NOx emissions. Requests for CAIR NOx annual allowances
should be made on or before May 1 st, and requests for CAIR NOx ozone season allowances
should be made on or before February 1 st. Please note that this year's scheduled periodic
reallocation review will be delayed due to BPA's impending revisions to the CAIR rule.
Should you have any questions regarding this approval,please contact Glenn Sappie at (919) 715-
3822 or Alan Drake at [phone].
Sincerely,
