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 10-6.030 - Sampling Methods for Air Pollution Sources

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This rule defines methods for performing
				  emissions sampling on air pollution sources throughout Missouri when required
				  in the Air Conservation Commission emission rules. The purpose of this
				  rulemaking is to clean-up the incorporation by reference information in this
				  rule to address the U.S. Environmental Protection Agency (EPA) concerns. The
				  evidence supporting the need for this proposed rulemaking, per 536.016, RSMo,
				  is an email dated September 18, 2018 from EPA.
PUBLISHER'S NOTE: The secretary of state has
				  determined that the publication of the entire text of the material which is
				  incorporated by reference as a portion of this rule would be unduly cumbersome
				  or expensive. This material as incorporated by reference in this rule shall be
				  maintained by the agency at its headquarters and shall be made available to the
				  public for inspection and copying at no more than the actual cost of
				  reproduction. This note applies only to the reference material. The entire text
				  of the rule is printed here.
(1) Samples and velocity traverses for source
				sampling shall be conducted using Method 1 as specified by 40 CFR part 60,
				Appendix A in section (22) of this rule.
(2) The velocity of stack gases shall be
				determined by measuring velocity head using a Type "S" (Stauscheibe or reverse
				type) pitot tube using Method 2 as specified by 40 CFR part 60, Appendix A in
				section (22) of this rule.
(3) The
				carbon dioxide, oxygen, excess air, and dry molecular weight contained in stack
				gases shall be determined using Method 3 as specified by 40 CFR part 60,
				Appendix A in section (22) of this rule.
(4) The moisture content in stack gases shall
				be determined using Method 4 as specified by 40 CFR part 60, Appendix A in
				section (22) of this rule.
(5)
				Particulate Matter Emissions.
(A) The
				concentration of particulate matter emissions in stack gases shall be
				determined using Method 5 as specified by 40 CFR part 60, Appendix A in section
				(22) of this rule.
(B) The quantity
				of particulate matter emissions from certain industrial processes as determined
				by the director shall be determined using Method 17 as specified by 40 CFR part
				60, Appendix A in section (22) of this rule.
(C) The concentration of particulates of
				PM10 shall be determined using Method 201 as specified
				by 40 CFR part 51, Appendix M in section (21) of this rule. When water droplets
				are known to exist in emissions, use Method 5 as defined in subsection (5)(A)
				of this rule and consider the particulate catch to be
				PM10 emissions.
(D) The concentration of particulates of
				PM10 shall be determined using Method 201A as specified
				by 40 CFR part 51, Appendix M in section (21) of this rule. When water droplets
				are known to exist in emissions, use Method 5 as defined in subsection (5)(A)
				of this rule and consider the particulate catch to be
				PM10 emissions.
(E) The concentration of condensable
				particulate matter (CPM) emissions in stack gases shall be determined using
				Method 202 and Conditional Test Method 039 as specified by 40 CFR part 51,
				Appendix M in section (21) of this rule may be used to determine the total
				PM10 and PM2.5 fraction of
				filterable particulate matter including condensables.
(F) The concentration of
				PM2.5 emissions in stack gases shall be determined using
				Method 202 and Conditional Test Method 040 as specified by 40 CFR part 51,
				Appendix M in section (21) of this rule. EPA Conditional Test Method 039 as
				specified in 40 CFR part 51, Appendix M in section (21) of this rule may be
				used to determine the total PM10 and
				PM2.5 fraction of filterable particulate matter
				including condens-ables.
