Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 10 - Air Conservation Commission › Chapter 6 - Air Quality Standards, Definitions, Sampling and Reference Methods and Air Pollution Control Regulations for the Entire State of Missouri › Section 10 CSR 10-6.220 - Restriction of Emission of Visible Air Contaminants

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: The purpose of this rulemaking is to comply
				  with Executive Order 17-03 criteria and will remove the unnecessary use of
				  restrictive words. This rulemaking will also add definitions specific to this
				  rule, remove a requirement for Portland cement kilns to install a continuous
				  monitoring system, update incorporations by reference, and make other changes
				  to clarify rule language. The evidence supporting the need for this proposed
				  rulemaking, per 536.016, RSMo, is Executive Order 17-03.
PURPOSE: This rule specifies the maximum allowable
				  opacity of visible air contaminant emissions and requires the use of continuous
				  monitoring systems (CMS) on certain air contaminant emission
				  units.
(1) Applicability.
				This rule applies to all sources of visible emissions, excluding water vapor,
				throughout the state of Missouri with the exception of the following:
(A) Internal combustion engines;
(B) Wood burning stoves or fireplaces used
				for heating;
(C) Fires used for
				recreational or ceremonial purposes or fires used for the noncommercial
				preparation of food by barbecuing;
(D) Fires used solely for the purpose of
				fire-fighter training;
(E) Smoke
				generating devices when a required permit (under
				10 CSR
				10-6.060 or
				10 CSR 10-6.065
				) has been issued or a written determination that a permit is not required has
				been obtained;
(F) The pyrolysis of
				wood for the production of charcoal in batch-type charcoal kilns regulated
				under 10
				CSR 10-6.330;
(G) Truck dumping of nonmetallic minerals
				into any screening operation, feed hopper, or crusher;
(H) Emission units specifically exempt or
				regulated under 10 CSR 10-6.070;
(I) Any open burning that is exempt from open
				burning rule
				10 CSR
				10-6.045;
(J) Emission units regulated under 40 CFR 63
				subpart DDDDD-National Emission Standards for Hazardous Air Pollutants for
				Major Sources: Industrial, Commercial, and Institutional Boilers and Process
				Heaters that meet one (1) of the following criteria:
1. Constructed or reconstructed after June 4,
				2010;
2. The unit is subject to a
				ten percent (10%) opacity limit as described in Table 4 of 40 CFR 63 subpart
				DDDDD; or
3. The unit is in Table 2
				of 40 CFR 63 subpart DDDDD and has a filterable particulate matter limitation
				of less than or equal to 4E-02 pounds per million British thermal units
				(lbs/MMBtu);
(K) Fugitive
				emissions regulated under
				10 CSR
				10-6.170;
(L) Any emission unit burning only natural
				gas, landfill gas, propane, liquefied petroleum gas, digester gas, or refinery
				gas;
(M) Emission units regulated
				under 40 CFR 63 subpart JJJJJJ-
National Emission Standards for
				Hazardous Air Pollutants for Industrial, Commercial, and Institutional Boilers
				Area Sources
that meet all of the following criteria:
1. Constructed or reconstructed after June 4,
				2010;
2. In compliance with the
				3.0E-02 lbs/MMBtu filterable particulate matter emission limit described in
				Table 1 of 40 CFR 63 subpart JJJJJJ or maintaining opacity to less than or
				equal to ten percent (10%) as described in Table 3 of 40 CFR 63 subpart JJJJJJ;
				and
3. Demonstrating compliance
				with a continuous monitoring system (CMS), including a continuous emission
				monitoring system (CEMS), a continuous opacity monitoring system (COMS), or a
				continuous parameter monitoring system (CPMS);
(N) Emission units regulated under 40 CFR 63
				subpart UUUUU-Mercury and Air Toxics Standards, and demonstrating compliance
				with a particulate matter continuous emission monitoring system;
(O) Emission units that are contained within
				and emit only within a building space. This does not include emission units
				with a capture device vented outside the building space; and
(P) Emission units subject to an equivalent
				or more restrictive emission limit under-
1.
											10 CSR
				10-6.075; or
2. Any federally enforceable
				permit.
