10 CSR 10-6.030 Sampling Methods for

Air Pollution Sources 

PURPOSE: This rule defines methods for

performing emissions sampling on air pollution sources throughout Missouri, only as

specified by the Air Conservation Commission emission rules. 

(1) Samples and velocity traverses for source

sampling shall be conducted as specified by

40 CFR part 60 Appendix A Test Methods,

Method 1—Sample and Velocity Traverses for

Stationary Sources.

(2) The velocity of stack gases is to be determined by measuring velocity head using a

Type “S” (Stauscheibe or reverse type) pitot

tube as specified by 40 CFR part 60,

Appendix A—Test Methods, Method 2—

Determination of Stack Gas Velocity and Volumetric Flow Rate (Type S Pitot Tube).

(3) The carbon dioxide, oxygen, excess air

and dry molecular weight contained in stack

gases shall be determined as specified by 40

CFR part 60, Appendix A—Test Methods,

Method 3—Gas Analysis for Carbon Dioxide,

Oxygen, Excess Air and Dry Molecular

Weight.

(4) The moisture content in stack gases shall

be determined as specified by 40 CFR part

60, Appendix A—Test Methods, Method 4—

Determination of Moisture Content in Stack

Gases.

Method).

(C) The concentration of particulates of

PM10 shall be determined as specified by 40

CFR part 51, Appendix M—Test Methods,

Method 201—Determination of PM10 Emis -

sions (Exhaust Gas Recycle Procedure).

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 as specified by 40

CFR part 51, Appendix M—Test Methods,

Method 201A—Determination of PM10 Emis -

sions (Constant Sampling Rate Procedure).

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 condensible particulate matter (CPM) emissions in stack

gases shall be determined as specified by 40

CFR part 51, Appendix M—Test Methods,

MISSOURI AIR CONSERVATION COMMISSION 

WILL HOLD PUBLIC HEARING 

JEFFERSON CITY, MO -- The Missouri Air Conservation Commission will hold a public hearing on 

Thursday, September 26, 2013 beginning at 9 a.m. at the Holiday Inn, CoCo Key, 9103 East 39th Street, 

Grand BC, Kansas City, Missouri. The commission will hear testimony related to the following proposed 

action(s): 

 

* 10 CSR 10-6.020 (amendment) Definitions and Common Reference Tables 

 

This proposed amendment will provide a maintenance update to add definitions needed for other 

rulemakings filed while the general definitions rule was being changed and remove obsolete 

definitions. In addition, several non-substantive error corrections and clarification will be made. 

 

The above rule action will be submitted for inclusion in the Missouri State Implementation Plan, for inclusion 

in the plan established under Clean Air Act Section 111(d) covering existing sources of noncriteria pollutants, 

and the Missouri Title V program. 

 

* 10 CSR 10-6.161 (new rule) Commercial and Industrial Solid Waste Incinerators 

 
2

This rulemaking will incorporate by reference the regulatory requirements of 40 CFR 60, subpart 

DDDD - Emission Guidelines and Compliance Times for Commercial and Industrial Solid Waste 

Incineration (CISWI) Units which was promulgated by the U.S. Environmental Protection Agency 

(EPA) on February 7, 2013. To meet the obligations of section 111(d) of the Clean Air Act (CAA), 

states must submit plans by February 7, 2014 to control certain hazardous and other air pollutants at 

existing solid waste incineration units. Incorporation of this federal regulation into a state rule will 

shift enforcement authority for existing CISWI units from EPA to the State of Missouri. 

 

The above rule action will not be submitted for inclusion in the Missouri State Implementation Plan but will 

be submitted for inclusion in the plan established under Clean Air Act Section 111(d) covering existing 

sources of noncriteria pollutants. 

 

* Clean Air Act Section 111(d)/129 State Plan Revision — Section 111(d)/129 State Plan for 

Implementation of the Commercial and Industrial Solid Waste Incinerator Emission Guidelines for 

Missouri 

 

Pursuant to sections 111(d) and 129 of the Clean Air Act, this plan was developed to demonstrate that 

the State of Missouri has the legal authority and enforceable mechanism in place to implement and 

enforce the Emission Guidelines and Compliance Times as set forth by the EPA in 40 CFR 60, 

Subpart DDDD for existing Commercial and Industrial Solid Waste Incinerators. The plan references 

legal authority established in chapter 536 of the Revised Statutes of Missouri (RSMo) and the 

enforceable mechanism provided by the proposed new state rule, 10 CSR 10-6.161 Commercial and 

Industrial Solid Waste Incinerators. This plan provides source and emission inventories of affected 

existing commercial and industrial solid waste incinerators in the state. It also establishes emission 

limits, operating requirements and compliance times that are consistent with the federal emission 

guidelines as promulgated. 

 

The above plan action will not be submitted for inclusion in the Missouri State Implementation Plan but will 

be submitted for inclusion in the plan established under Clean Air Act Section 111(d) covering existing 

sources of noncriteria pollutants. 

 

If the Commission adopts the action(s), it will be the Department’s intention to submit the action(s) to the 

U.S. Environmental Protection Agency to be included in Missouri’s State Implementation Plan unless 

otherwise noted above.

1 I am here to present testimony on the

2 proposed amendment to 10 CSR 10-6.020, Definitions

3 and Common Reference Tables. This rule amendment

4 begins on page 73 of your briefing document.

5 This Proposed Amendment provides a

6 maintenance update to the general definitions rule,

7 which applies to the entire State of Missouri. As

8 you may recall, all of the air rule definitions

9 were consolidated into the general definitions rule

10 in 2011 as supported by the Air Program Advisory

11 Forum. This rulemaking is administrative in nature

12 serving to maintain a clear, consistent, and up-to13 date single set of definitions without imposing any

14 new requirements on sources.

15 The main elements of this rulemaking

16 include:

17 Moving terms already defined in specific

18 rules into the general definitions rule consistent

19 with the practice of consolidating all air rule

20 definitions, for example, Plug-in hybrid electric

21 vehicle;

22 Adding general definitions for terms

23 that previously only had unique definitions to

24 specific rule applications, for example, Facility;

25 Removing obsolete terms no longer used
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

PROPOSED AMENDMENT

10 CSR 10-6.020 Definitions and Common Reference Tables. The

commission proposes to amend section (1) and subsections

(2)(A)–(2)(I), (2)(L), (2)(N)–(2)(P), (2)(R)–(2)(T), and

(2)(V)–(2)(W). If the commission adopts this rule action, it will be the

department’s intention to submit this rule amendment to the U.S.

Environmental Protection Agency to replace the current rule that is in

the Missouri State Implementation Plan. The evidence supporting the

need for this proposed rulemaking is available for viewing at the

Missouri Department of Natural Resources’ Air Pollution Control

Program at the address listed in the Notice of Public Hearing at the end

of this rule. More information concerning this rulemaking can be found

at the Missouri Department of Natural Resources’ Environmental

Regulatory Agenda website, www.dnr.mo.gov/regs/index.html.

PURPOSE: This rule defines key words and expressions used in

Chapters 1 through 6 and provides common reference tables. This

amendment will provide a maintenance update to add definitions

needed for other rulemakings filed while the general definitions rule

was being changed and remove obsolete definitions. In addition, several nonsubstantive error corrections and clarifications will be made.

The evidence supporting the need for this proposed rulemaking, per

536.016, RSMo, is the public hearing testimony for this rulemaking.

(1) Applicability. This rule shall apply throughout Missouri defining

terms and expressions used in all Title 10, Division 10—Air

Conservation Commission rules. If a definition in this rule conflicts

with a definition in any other 10 CSR 10 rule, the definition in 10

CSR 10-6.020 shall take precedence with the exception [of] that

federal definitions [pertaining to 10 CSR 10-6.060] incorporated by reference into a 10 CSR 10 rule take precedence over definitions in 10 CSR 10-6.020.

Proposed Amendment Text Reminder:

Boldface text indicates new matter.

[Bracketed text indicates matter being deleted.]

Under this heading will appear the text of proposed rules

and changes. The notice of proposed rulemaking is

required to contain an explanation of any new rule or any

change in an existing rule and the reasons therefor. This is set

out in the Purpose section with each rule. Also required is a

citation to the legal authority to make rules. This appears following the text of the rule, after the word “Authority.”

Entirely new rules are printed without any special symbology under the heading of proposed rule. If an existing

rule is to be amended or rescinded, it will have a heading of

proposed amendment or proposed rescission. Rules which

are proposed to be amended will have new matter printed in

boldface type and matter to be deleted placed in brackets.

An important function of the Missouri Register is to solicit

and encourage public participation in the rulemaking

process. The law provides that for every proposed rule,

amendment, or rescission there must be a notice that anyone

may comment on the proposed action. This comment may

take different forms.

I

f an agency is required by statute to hold a public hearing

before making any new rules, then a Notice of Public

Hearing will appear following the text of the rule. Hearing

dates must be at least thirty (30) days after publication of the

notice in the Missouri Register. If no hearing is planned or

required, the agency must give a Notice to Submit

Comments. This allows anyone to file statements in support

of or in opposition to the proposed action with the agency

within a specified time, no less than thirty (30) days after publication of the notice in the Missouri Register. 

An agency may hold a public hearing on a rule even

though not required by law to hold one. If an agency

allows comments to be received following the hearing date,

the close of comments date will be used as the beginning day

in the ninety- (90-) day-count necessary for the filing of the

order of rulemaking.

I

f an agency decides to hold a public hearing after planning

not to, it must withdraw the earlier notice and file a new

notice of proposed rulemaking and schedule a hearing for a

date not less than thirty (30) days from the date of publication

of the new notice.

Note: For all listings in this table that contain the word compounds and for glycol ethers, the following applies: Unless otherwise

specified, these listings are defined as including any unique chemical substance that contains the named chemical (that is, 

antimony, arsenic, and the like) as part of that chemical’s infrastructure. 

1 X’CN where X–H’ or any other group where a formal dissociation may occur, for example, KCN or Ca(CN)2. 

2 Includes mono- and diethers of ethylene glycol, diethylene glycol and triethylene 

 glycol R-(OCH2CH2)n-OR’ where n = 1, 2, or 3; R = Alkyl or aryl groups; R’ = R, H, or groups which, when removed, yield 

glycol ethers with the structure R-(OCH2CH2)n-OH. Polymers and ethylene glycol monobutyl ether are excluded from the 

glycol category. 

3 Includes glass microfibers, glass wool fibers, rock wool fibers, and slag wool fibers, each characterized as respirable (fiber 

diameter less than three and one-half (3.5) micrometers) and possessing an aspect ratio (fiber length divided by fiber diameter) 

greater than or equal to three (3), as emitted from production of fiber and fiber products. 

4 Includes organic compounds with more than one (1) benzene ring, and which have a boiling point greater than or equal to one 

hundred degrees Celsius (100 °C). 

5 A type of atom which spontaneously undergoes radioactive decay.
