Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 10 - Air Conservation Commission › Chapter 5 - Air Quality Standards and Air Pollution Control Rules Specific to the St. Louis Metropolitan Area › Section 10 CSR 10-5.510 - Control of Emissions of Nitrogen Oxides

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: The purpose of this regulation is to reduce
				  the emissions of nitrogen oxides in the St. Louis ozone nonattainment area.
				  This regulation requires major sources of Nitrogen Oxides
				  (NOX ) to install or comply with reasonably available
				  control technology (RACT) as required under the Clean Air Act.
(1) Applicability.
(A) This rule shall apply to all
				installations located in the counties of Franklin, Jefferson, St. Charles and
				St. Louis and the City of St. Louis with the potential to emit one hundred
				(100) tons or greater per year of nitrogen oxides.
(B) Installations affected by this rule shall
				be in compliance no later than May 1, 2002. The director may grant an extension
				of the compliance deadline if the affected installation submits an alternative
				compliance plan no later than January 1, 2001. The alternative compliance plan
				shall include the following items:
1. For each
				affected unit, a detailed analysis of the air quality benefit that will occur
				if the compliance date is extended;
2. For each affected unit, a detailed
				explanation of the reasons why the owner or operator believes that compliance
				with the applicable NOx emissions limit by May 1, 2002
				is impractical;
3. Information
				sufficient to identify each affected unit;
4. A proposed schedule setting dates by which
				the owner or operator will complete the following milestones for each affected
				unit:
A. Applications for all necessary
				permits;
B. Contracts for the
				implementation of new units or control equipment;
C. Construction and installation of new units
				or control equipment; and
D.
				Compliance with the applicable NOx emissions limitation
				established in this rule; and
5. Any other information the director
				requests.
(C)
				Exemptions. The requirements of this rule shall not apply to the following
				emission units:
1. Any boiler having a
				maximum heat input of less than fifty (50) million British thermal units
				(mmBtu) per hour;
2. Any stationary
				internal combustion engine having a rated energy output capacity of less than
				five hundred (500) horsepower or a maximum heat input capacity of twenty (20)
				mmBtu per hour or less;
3. Any
				stationary combustion turbine having a rated maximum heat input capacity of
				less than twenty (20) mmBtu per hour;
4. Any emergency standby boiler, stationary
				internal combustion engine, stationary combustion turbine, start up unit, or
				black start unit which operates less than seven hundred and fifty (750) hours
				annually and less than four hundred (400) hours during ozone season;
5. Any research and development emissions
				unit;
6. Any jet engine test
				cell;
7. Any air pollution control
				device;
8. Any emission unit which
				is required to meet a more stringent state or federal
				NOx
emissions limitation;
9. Any unit that would otherwise be required
				to comply with this rule with actual annual NOx
				emissions of thirty (30) tons per year or less. This exemption shall cease to
				apply to a unit if the unit ever exceeds thirty (30) tons per year of actual
				NOx emissions for any calendar year. Any unit that
				becomes affected by this rule due to failure to maintain this exemption after
				January 1, 2000 shall immediately notify the department in writing that the
				rule applies. The unit shall be in compliance with the applicable provisions of
				this rule within twenty-four (24) months after notifying the department or May
				1, 2002, whichever is later;
10.
				Any unit subject to and in compliance with Phase II acid rain requirements;
				and
11. Any incinerator having a
				maximum rated heat input capacity of less than fifty (50) mmBtu per
				hour.
