(7) Electric System Reliability During Ozone
				  Seasons.
(a) An exceedance of the
				  NOx limitations in §B(4) or (6) of this regulation which
				  occurs because PJM Interconnection, LLC or a successor independent system
				  operator, acts to invoke "Maximum Emergency Generation", "Load Reduction",
				  "Voltage Reduction", "Curtailment of Non-essential Building Load", or "Manual
				  Load Dump" procedures in accordance with the current PJM Manual, or a PJM alert
				  preceding such action as to a generating unit that has temporarily shut down in
				  order to avoid potential interruption in electric service and maintain electric
				  system reliability is not a violation of this chapter provided that:
(i) Within 36 hours following the action, the
				  owner or operator of the affected electric generating unit or units notifies
				  the Manager of the Air Quality Compliance Program of the action taken by PJM
				  Interconnection and provides the Department with documentation of the action
				  which is satisfactory to the Department;
(ii) Within 48 hours after completion of the
				  action, the owner or operator of the affected unit or units provides the
				  Department with the estimated NOx emissions in excess of
				  the emission limitation; and
(iii)
				  Not later than December 31 of the year in which the emission limitation is
				  exceeded, the owner or operator of the affected generating unit or units
				  transfers to the Maryland Environmental Surrender Account, ozone season
				  NOx allowances equivalent in number to the tons of
				  NOx emitted in excess of the emission limitation in
				  §B(4) or (6), as applicable.
(b) The owner or operator of an electric
				  generating unit or system, as applicable, shall send written notice to the
				  Manager of the Air Quality Compliance Program not later than 5 business days
				  following the day when the cumulative ozone season NOx
				  emissions of an electric generating unit or system, as applicable, are:
(i) Equal to approximately 80 percent of the
				  applicable ozone season emission limitation; and
(ii) Equal to the applicable ozone season
				  emission limitation.
