Md. Code Regs. 26.11.38.04 - Additional NO[x] Emission Control Requirements
A. This regulation applies to C.P. Crane
units 1 and 2, Chalk Point unit 2, Dickerson units 1, 2, and 3, and H.A. Wagner
unit 2.
B. General Requirements.
The owner or operator of the affected electric generating units subject to this
regulation shall choose from the following:
(1) Not later than June 1, 2020:
(a) Install and operate a selective catalytic
reduction (SCR) control system; and
(b) Meet a NOx
emission rate of 0.09 lbs/MMBtu, as determined on a 30-day rolling average
during the ozone season;
(2) Not later than June 1, 2020, permanently
retire the unit;
(3) Not later than
June 1, 2020, permanently switch fuel from coal to natural gas for the
unit;
(4) Not later than June 1,
2020, meet either a NOx emission rate of 0.13 lbs/MMBtu
as determined on a 24-hour systemwide block average or a systemwide
NOx tonnage cap of 21 tons per day during the ozone
season.
C. When option
B(4)of this regulation is selected:
(1) Not
later than May 1, 2016, the owner or operator of an affected electric
generating unit shall not exceed a NOx 30-day systemwide
rolling average emission rate of 0.13 lbs/MMBtu during the ozone
season.
(2) Not later than May 1,
2018, the owner or operator of an affected electric generating unit shall not
exceed a NOx 30-day systemwide rolling average emission
rate of 0.11 lbs/MMBtu during the ozone season.
(3) Not later than May 1, 2020, the owner or
operator of an affected electric generating unit shall not exceed a
NOx 30-day systemwide rolling average emission rate of
0.09 lbs/MMBtu during the ozone season.
D. In order to calculate the 24-hour
systemwide block average emission rate and systemwide
NOx tonnage cap under §B(4) of this regulation and the
systemwide rolling average emission rates under §C of this regulation:
(1) The owner or operator shall use all
affected electric generating units within their system as those terms are
defined in Regulation .01B of this chapter; and
(2) The unit or units
NOx emissions from all operations during the entire
operating day shall be used where the unit or units burn coal at any time
during that operating day.
E. Beginning June 1, 2020, if the unit or
units included in a system, as that system existed on May 1, 2015, is no longer

or controller of the system:
(1) The
remaining units within the system shall meet either:
(a) The requirements of §B(1)-(3) of this
regulation; or
(b) A
NOx emission rate of 0.13 lbs/MMBtu as determined on a
24-hour systemwide block average and the requirements of §C(3) of this
regulation.
(2) The unit
or units no longer included in the system shall meet the requirements of
§B(1)-(3) of this regulation.
