North Carolina Administrative Code › Title 15A - Environmental Quality › Chapter 02 - Environmental Management › Subchapter D - AIR POLLUTION CONTROL REQUIREMENTS › Section .1400 - NITROGEN OXIDES › Section 02D .1409 - STATIONARY INTERNAL COMBUSTION ENGINES

Current through Register Vol. 39, No. 2, July 15, 2024
(a)
				  This Rule applies geographically pursuant to
				  15A NCAC
				  02D .1402.
(b) The owner or operator of a stationary
				  internal combustion engine with a rated capacity of greater than or equal to
				  650 horsepower that is not covered under Paragraph (c) of this Rule or
				  15A NCAC
				  02D .1418 shall not allow emissions of NOx
				  from the stationary internal combustion engine to exceed the following
				  limitations:
MAXIMUM ALLOWABLE NOx EMISSION RATES FOR STATIONARY
					 INTERNAL COMBUSTION ENGINES
(GRAMS PER HORSEPOWER HOUR)
Engine Type
Fuel Type
Limitation
Rich-burn
Gaseous
2.5
Lean-burn
Gaseous
2.5
Compression
Ignition Liquid
8.0
(c) Engines identified in the table in this
				  Paragraph shall not exceed the emission limit in the table during the ozone
				  season.
SUM OF MAXIMUM ALLOWABLE OZONE SEASON NOx
								EMISSIONS
(tons per ozone season)
FACILITY
REGULATED SOURCES
ALLOWABLE EMISSIONS
Transcontinental Gas Pipeline Station 150
Mainline engines #12, 13, 14, and 15

Transcontinental Gas Pipeline Station 155
Mainline engines #2, 3, 4, 5, and 6
127
Transcontinental Gas Pipeline Station 160
Mainline engines #11, 12, 13, 14, and 15

Compliance shall be determined by summing the actual
					 emissions from the engines listed in the table at each facility for the ozone
					 season and comparing those sums to the limits in the table. Compliance may be
					 achieved through trading under Paragraph (h) of this Rule if the trades are
					 approved before the ozone season.
(d) If the emissions from a stationary
				  internal combustion engine are greater than the applicable limitation in
				  Paragraph (b) of this Rule after applying a reasonable effort as defined in
				  15A NCAC
				  02D .1401, or if the requirements of this
				  Rule are not RACT for the particular stationary internal combustion engine, the
				  owner or operator may petition the Director for an alternative limitation or
				  standard pursuant to
				  15A NCAC
				  02D .1412.
(e) For the engines identified in Paragraph
				  (c) of this Rule and any engine involved in emissions trading with one or more
				  of the engines identified in Paragraph (c) of this Rule, the owner or operator
				  shall determine compliance using:
(1) a
				  continuous emissions monitoring system that meets the applicable requirements
				  of Appendices B and F of 40 CFR part 60 and
				  15A NCAC
				  02D .1404; or
(2) an alternate monitoring and recordkeeping
				  procedure based on actual emissions testing and correlation with operating
				  parameters.
The installation, implementation, and use of an alternate
					 procedure allowed under Subparagraph (2) of this Paragraph shall be approved by
					 the Director before it may be used. The Director shall approve the alternative
					 procedure if he or she finds that it can show the compliance status of the
					 engine.
