APCO 

The Missouri Air Conservation Commission has recently revised or promulgated the 

following regulation(s) for the Missouri State Implementation Plan (SIP). The following 

is enclosed for your review: , 

10 CSR 10-6.130 Controlling Emissions During Episodes of High Air Pollution Potential 

This amendment updates a table by removing the pollutant concentration breakpoints that 

became inaccurate each time the National Ambient Air Quality Standards change, 

clarifying the requirement for sources to provide the Department with an emissions 

reduction plan when requested, clarifying rule provisions, and removing definitions that 

can be found in 10 CSR 10-6.020, Definitions and Common Reference Tables. 

The commission adopted the enclosed rule action(s) on August 29, 2013, after 

considering comments received at public hearing and throughout the open public 

comment period. The commission has full legal authority to develop rules pursuant to 

Section 643.050 of the Missouri Air Conservation Law. The state followed all applicable 

administrative procedures in proposing and adopting the rule action(s). Enclosed are the 

required SIP submittal elements for determination of plan completeness per 40 CFR Part 

51, Appendix V. 

The Missouri Department ofNatural Resources requests that the U.S. Environmental 

Protection Agency amend the SIP to replace the current rule(s) in the SIP. 

Compliant with the April 6, 2011 SIP regional consistency memo, an exact duplicate of 

this submittal is also being provided as an electronic attachment in an email to the Region 

VII Missouri coordinator.

10 CSR 10-6.130 Controlling Emissions

During Episodes of High Air Pollution

Potential

PURPOSE: This rule specifies the conditions

that establish air pollution alert and emergency alert levels and the associated procedures and emissions reduction objectives. 

(1) Applicability.

(A) This rule shall apply to all sources and

premises throughout the entire state with air

emissions that contribute to sulfur dioxide

(SO2), carbon monoxide (CO), ozone (O3),

nitrogen dioxide (NO2), or Particulate Matter—10 Micron (PM10) and 2.5 Micron

(PM2.5).

(B) The boundaries of the affected area

shall be determined at the discretion of the

director in accordance with the nature and

magnitude of the pollutant concentrations and

meteorological conditions that cause the

alert.

(2) Definitions. Definitions of certain terms

specified in this rule may be found in 10 CSR

10-6.020. 

(3) General Provisions.

(A) Air Pollution Alerts.

1. The Air Quality Index shall be reported to the general public on a daily basis by all

metropolitan statistical areas with a population exceeding three hundred fifty thousand

(350,000).

2. Alert levels for applicable air pollutants are stated in terms of the Air Quality

Index (AQI) as defined in 40 CFR 58,

Appendix G. Table A shows the relation of

the AQI ranges to alert categories.

3. Alert types and levels of initiation. If

an AQI value falls within the AQI range listed in Table A of this rule, the corresponding

alert color shall be initiated. 

4. Declaration of alerts. An orange alert,

red alert, purple alert, or maroon emergency

alert may be declared on the basis of deteriorating air quality alone; an Air Stagnation

Advisory need not be in effect. The appropriate alert level should be declared by the

director as ambient monitoring would indicate.

5. Termination of alerts. When, in the

judgment of the director, meteorological conditions and pollutant concentrations warrant

discontinuance of any alert condition, the

director shall notify the technical staff, the

chairman, and members of the Missouri Air

Conservation Commission that the alert has

been discontinued and issue a public notice to

that effect.

(B) Conditions. This subsection provides

conditions that establish alert level categories.

Credit for Reduced Pollutant Con -

centrations From the Use of Dispersion

Techniques

PURPOSE: This rule implements provisions

of federal regulations which restrict credit in

the calculation of emission limitations for

reduced pollutant concentrations due to the

use of dispersion techniques.

(1) Applicability. This rule shall apply to the

procedures to account for emission dispersion

techniques used in the calculation of any emission limitation or any revision of any limitation to be established by the director or to be

considered for establishment by the Missouri

Air Conservation Commission (MACC). This

rule also requires that all emission limitations

established by the director or by the MACC

after December 31, 1970, be reviewed for

compliance with this rule.

(2) General.

(A) The degree of emission limitation

required of any installation for control of any

air pollutant must not be affected by that portion of any installation’s stack height that

exceeds good engineering practice (GEP) or

by any other dispersion technique, except as

provided in section (3).

(B) Before the director or the MACC

establishes an emission limitation that is

based on a GEP stack height that exceeds the

formula GEP height allowed by 10 CSR 10-

6.020(2)(G)2.B., the director must notify the

public of the availability of the demonstration

study and must provide opportunity for public hearing on it.

(C) This rule does not restrict the actual

stack height of any installation or the use of

any dispersion technique by any installation.

(3) Exemptions. The provisions of section (2)

shall not apply to emission limitation credits

from—

(A) Stack heights on which construction

commenced on or before December 31,

1970, except where pollutants are being emitted from the stacks by source operations

which were constructed, or reconstructed or

on which major modifications were carried

out after December 31, 1970; or

(B) Dispersion techniques implemented

before December 31, 1970, except where

these dispersion techniques are being applied

to source operations which were constructed,

or reconstructed or on which major modifications were carried out after December 31,

10 CSR 10-6.040 (amendment) Reference Methods

This proposed amendment will update the incorporation by reference in section (4) to 

include the latest Federal Register promulgation dates. Recent Federal Register Notices 

add Federal Equivalency Methods (FEMs) for ambient monitoring of nitrogen dioxide and 

fine particulate matter; and two FEMs for laboratory analysis of lead. Adding the latest 

Federal Register promulgation dates to this rule will allow the latest FEMs to be used to 

meet state requirements. The ASTM Methods for determining parameters such as fuel 

sulfur and heat content are also being updated to the latest versions available.

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 10-6.130 Controlling Emissions During Episodes of High

Air Pollution Potential. The commission proposes to amend the rule

purpose, amend subsection (1)(A), and amend sections (2), (3), and

(4). 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 specifies the conditions that establish air pollution alert and emergency alert levels and the associated procedures

and emissions reduction objectives. The purpose of this amendment

is to update a table by removing the pollutant concentration breakpoints that become inaccurate each time the National Ambient Air

Quality Standards change, clarify the requirement for sources to provide the department with an emissions reduction plan when requested, clarify rule provisions, and remove definitions that can be found

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

evidence supporting the need for this proposed rulemaking, per

536.016, RSMo, is a rule comment form dated July 26, 2011, from

Missouri Department of Natural Resources staff.

PURPOSE: This rule specifies the conditions that establish [an] air

pollution alert[, watch, or emergency] and emergency alert levels and the associated procedures and emissions reduction objectives

[for dealing with each]. 

(1) Applicability.

(A) This rule shall apply to all [emissions from any source or

from any premises] sources and premises throughout the entire

state with air emissions that contribute to sulfur dioxide (SO2),

carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), or

Particulate Matter—10 Micron (PM10) and 2.5 Micron (PM2.5).

(2) Definitions. Definitions of certain terms specified in this rule

may be found in 10 CSR 10-6.020. 

[(A) Air pollution alert—The level of an air pollution

episode known as an air pollution alert is that condition

when the concentration of air contaminants reach the level

at which the first stage control actions are to begin.

(B) Air Stagnation Advisory—A special bulletin issued by

the National Weather Service entitled “Air Stagnation

Advisory,” which is used to warn air pollution control agencies that stagnant atmospheric conditions are expected

which could cause increased concentrations of air contaminants near the ground.

(C) Area—For the purpose of this rule, any or all regions

within the boundaries of the state of Missouri.

(D) Definitions of certain terms specified in this rule, other

than those specified in this rule section, may be found in 10

CSR 10-6.020.]

(3) General Provisions.

(A) Air Pollution Alerts.

1. The Air Quality Index shall be reported to the general public on a daily basis by all metropolitan statistical areas with a population exceeding three hundred fifty thousand (350,000).

2. Alert levels for applicable air pollutants are stated in terms

of the Air Quality Index (AQI) as defined in 40 CFR [part] 58,

Appendix G[, for sulfur dioxide (SO2), carbon monoxide (CO),

ozone (O3), nitrogen dioxide (NO2), and Particulate Matter—

10 Micron (PM10) and 2.5 Micron (PM2.5)]. Table A shows the

relation of the AQI [breakpoint values to equivalent concentrations of air contaminants. All concentrations are averaged

over the time period indicated] ranges to alert categories.

Page 903 June 17, 2013

Vol. 38, No. 12 Missouri Register
3. Alert types and levels of initiation. If an AQI value falls

within the AQI range listed in Table A of this rule, the corresponding alert color shall be initiated. 

[A. Orange alert AQI value. Any one (1) of the contaminants listed in paragraph (3)(A)2. reaching a concentration

which results in an AQI value of one hundred one to one

hundred fifty (101–150) shall initiate the orange alert.

B. Red alert AQI value. Any one (1) of the contaminants listed in paragraph (3)(A)2. reaching a concentration

which results in an AQI value of one hundred fifty-one to

two hundred (151–200) shall initiate the red alert.

C. Purple alert AQI value. Any one (1) of the contaminants listed in paragraph (3)(A)2. reaching a concentration

which results in an AQI value of two hundred one to three

hundred (201–300) shall initiate the purple alert.

D. Maroon emergency alert AQI value. Any one (1) of

the contaminants listed in paragraph (3)(A)2. reaching a concentration which results in an AQI value of three hundred

one to five hundred (301–500) shall initiate the maroon

emergency alert.]

4. Declaration of alerts. An orange alert, red alert, purple alert,

or maroon emergency alert may be declared on the basis of deteriorating air quality alone; an Air Stagnation Advisory need not be in

effect. The appropriate [episode status] alert level should be

declared by the director as ambient monitoring would indicate.

5. Termination of alerts. When, in the judgment of the director,

meteorological conditions and pollutant concentrations warrant discontinuance of any alert condition, the director shall notify the technical staff, the chairman, and members of the Missouri Air

Conservation Commission that the alert has been discontinued and

issue a public notice to that effect.

(B) [Orange Alert.] Conditions. This subsection provides conditions that establish alert level categories. 

[1. Orange alert procedures shall be initiated by the

director if the following conditions are met:

A. An Air Stagnation Advisory is in effect;

B. The orange alert AQI value is equaled or exceeded

at any one (1) monitoring station within the affected area,

unless there is a current forecast of meteorological improvement within the next twenty-four (24) hours; and

C. Meteorological conditions are such that the pollutant concentrations can be expected to remain or reoccur at

the previously mentioned levels during the next twenty-four

(24) or more hours or increase unless control actions are

taken.

2. The following are orange alert procedures. The general public shall be informed through the news media that an

orange alert exists, the geographical area(s) where the alert

is applicable, the emission and type of source(s) that initiated the alert and encourage those with respiratory ailments

or heart conditions to take the most appropriate and expedient precautions.]

[(1) Areas are generally required to report the AQI based on eight (8)-hour ozone values. However, there are a small number

of areas where an AQI based on one (1)-hour ozone values would be more precautionary. In these cases, in addition to calculating the eight (8)-hour ozone index value, the one (1)-hour ozone index value may be calculated, and the maximum of the

two (2) values reported.

(2) NO2 has no short-term National Ambient Air Quality Standard and can generate an AQI value only above two hundred

(200).

(3) Eight (8)-hour O3 values do not define higher AQI values (greater than or equal to three hundred one (301)). AQI values of

three hundred one (301) or higher are calculated with one (1)-hour O3 concentrations.]
(C) [Red Alert.] Procedures. This subsection establishes procedures for addressing alert level conditions. 

[1. Red alert procedures shall be initiated by the director if the following conditions are met:

A. An Air Stagnation Advisory is in effect;

B. The red alert AQI value is equaled or exceeded at

any one (1) monitoring station within the affected area,

unless there is a current forecast of meteorological improvement within the next twenty-four (24) hours; and

C. Meteorological conditions are such that the pollutant concentrations can be expected to remain or reoccur at

the previously mentioned levels during the next twenty-four

(24) or more hours or increase unless control actions are

taken.

2. The following are red alert procedures:

A. All affected governmental control agencies shall be

notified that red alert conditions exist and that coordination

of action is required;

B. All hospitals within the affected area shall be notified that red alert conditions exist;

C. The frequency of air monitoring shall be increased

at all monitoring stations which are not continuous at intervals not exceeding one (1) hour, with continual hourly review

at a central control location, if this equipment is available

and it is deemed necessary by the director;

D. The general public shall be informed through the

news media that a red alert exists, the geographical area(s)

Title 10—DEPARTMENT OF NATURAL RESOURCES

Division 20—Clean Water Commission

Chapter 7—Water Quality

PROPOSED AMENDMENT

10 CSR 20-7.015 Effluent Regulations. The department is amending sections (1), (2), (3), (4), (5), (6), and subsection (7)(A), and

sections (8) and (9).

PURPOSE: This amendment will 1) update bacteria limits and monitoring requirements; 2) revise language regarding “bypasses” to

align with federal definition; 3) require quarterly effluent monitoring

of nutrient concentrations at large wastewater treatment facilities; 4)

provide clarification regarding whole effluent toxicity testing requirements; 5) allow for electronic reporting via web-based systems (once

available); 6) include provisions for developing effluent limits with

regard to several situations such as discharges to impaired waters,

tiered limits which allow higher discharge concentrations during

higher stream flow rates, and the use of local stream data to adjust

effluent limits; 7) reduce monitoring frequency for facilities that consistently comply with effluent limits; 8) eliminate schedule to comply

with phosphorus effluent limits for discharges to Table Rock Lake and

Lake Tanycomo because the dates have already passed; 9) require

limits for the discharge of nitrates that may impact specific drinking

water wells; 10) specify that operating permits may include schedules

of compliance in accordance with federal regulations; 11) revert to

pH effluent limits that were in a previous version of the regulation;

12) allow alternate compliance points for discharges to subsurface

waters; and 13) reorganize and clarify several elements of the rule.

impoundments created by the construction of a dam across any

waterway or watershed. An impoundment designed for or used as a

disposal site for tailings or sediment from a mine or mill shall be

considered a wastewater treatment device and not a lake or reservoir.

Releases to lakes and reservoirs include discharges into streams onehalf (1/2) stream mile (.80 km) before the stream enters the lake as

measured to its normal full pool (section (3) of this rule);

3. A losing stream is a stream which distributes thirty percent

(30%) or more of its flow through natural processes such as through

permeable geologic materials into a bedrock aquifer within two (2)

miles[’] flow distance downstream of an existing or proposed discharge. Flow measurements to determine percentage of water loss

must be corrected to approximate the seven (7)-day Q10 stream flow.

If a stream bed or drainage way has an intermittent flow or a flow

insufficient to measure in accordance with this rule, it may be determined to be a losing stream on the basis of channel development, valley configuration, vegetation development, dye tracing studies,

bedrock characteristics, geographical data, and other geological factors. Only discharges which in the opinion of the Missouri

Department of Natural Resources (department) reach the losing section and which occur within two (2) miles upstream of the losing section of the stream shall be considered releases to a losing stream. A

list of known losing streams is available in the Water Quality

Standards, 10 CSR 20-7.031 Table J—Losing Streams. Other streams

may be determined to be losing by the department (section (4) of this

rule);

4. Metropolitan no-discharge streams. These streams and the

limitations on discharging to them are listed in [the commission’s

Water Quality Standards] Table F of 10 CSR 20-7.031 Water

Quality Standards. This rule shall in no way change, amend, or be

construed to allow a violation of the existing or future water quality

standards (section (5) of this rule);

5. Special streams—[wild and scenic rivers, Ozark National

Scenic Riverways,] Outstanding National Resource Waters and

Outstanding State Resource Waters, as listed in Tables D and E of

10 CSR20-7.031(section (6) of this rule);

6. Subsurface waters in aquifers (section (7) of this rule); and

7. All other waters except as noted in paragraphs (1)(A)1.–6. of

this rule (section (8) of this rule).

(B) Sections (2) though (8) of this rule establish requirements

for discharges to the waters specified in these sections, and the

requirements of section (9) of this rule apply to all discharges.

The requirements of this rule do not apply to stormwater discharges; effluent limits for stormwater discharges are prescribed

in 10 CSR 20-6.200 Storm Water Regulations.

(2) Effluent Limitations for the Missouri and Mississippi Rivers. The

following limitations represent the maximum amount of pollutants

which may be discharged from any point source, water contaminant

source, or wastewater treatment facility.

(A) Discharges from wastewater treatment facilities which receive

primarily domestic waste or from publicly-owned treatment works

(POTWs) shall undergo treatment sufficient to conform to the following limitations:

1. Biochemical Oxygen Demand5 (BOD5) and Total Suspended

Solids (TSS) equal to or less than a monthly average of thirty milligrams per liter (30 mg/L) and a weekly average of forty-five milligrams per liter (45 mg/L);

2. pH shall be maintained in the range from six [and one-half]

to nine [(6.5–9.0)] (6–9) standard units;

3. Exceptions to paragraphs (2)(A)1. and 2. of this rule are as

follows:

A. If the facility is a wastewater lagoon, the TSS shall be

equal to or less than a monthly average of eighty milligrams per liter

(80 mg/L) and a weekly average of one hundred twenty milligrams

per liter (120 mg/L) and the pH shall be maintained above six [and

one-half (6.5)] 6.0, and the BOD5 shall be equal to or less than a

monthly average of forty-five milligrams per liter (45 mg/L) and a

weekly average of sixty-five milligrams per liter (65 mg/L);

B. If the facility is a trickling filter plant the BOD5 and TSS

shall be equal to or less than a monthly average of forty-five milligrams per liter (45 mg/L) and a weekly average of sixty-five milligrams per liter (65 mg/L);

MISSOURI

REGISTER

Vol. 38, No. 21

SUMMARY OF COMMENTS: The Missouri Department of Natural

Resources’ Air Pollution Control Program received four (4) comments

from one (1) source: the Boeing Company. 

COMMENT #1: The Boeing Company commented in support of the

proposed revisions referencing federal Air Quality Index levels, placing general provisions language into tables and clarifying that updated alert plans shall be provided when necessitated by changes to

operations. 

RESPONSE: The department’s Air Pollution Control Program

appreciates support for these proposed rule changes intended to

enhance accuracy and clarity. No changes have been made to the rule

text as a result of this comment. 

COMMENT #2: The Boeing Company requested the addition of

facility emission thresholds to the rule to set a minimum, below

which a facility would not be subject to a request to file an alert plan.

The threshold would streamline operating permits so facilities below

the threshold would not have this rule as an applicable requirement

in their operating permits. Since the activation of purple alert and

maroon emergency alert plans is unlikely, the requests for alert plans

should be limited to facilities that could significantly benefit air quality through curtailment of certain activities. 

RESPONSE: The department’s Air Pollution Control Program

acknowledges the benefits of adding emission thresholds and will consider making this change the next time the rule is open for amendment.

Since the current rule language closely follows U.S. Environmental

Protection Agency (EPA) example rule language, the Air Program

would need to work with EPA to ensure that the addition of emissions

thresholds would not conflict with federal requirements. While this

change would streamline operating permits by relieving some sources

of the burden of submitting an emergency alert emissions reduction

plan upon request, all sources would remain subject to actions

deemed necessary by the director and/or commission in order to alleviate or lessen the effects of any emergency condition. No changes

have been made to the rule text at this time as a result of this comment.

COMMENT #3: The Boeing Company requested a mechanism for

rescission of an alert plan when the plan becomes outdated or inaccurate due to changes in operations. An example would be if a facility drastically reduced emissions since the original submission of

their plan, it would be of little benefit for the director to require

implementation of this alert plan, especially when there are other

methods not included in the plan that would be a more effective contribution to remediation of the emergency air pollution episode. 

RESPONSE AND EXPLANATION OF CHANGE: As a result of

this comment, an adjustment was made to section (4) of the rule for

requesting rescissions of facility alert plans when changes to operations necessitate. 

COMMENT #4: The Boeing Company commented that this rule is

a candidate for the statutorily required rule review for the following

reasons: 1) elements of this rule and the EPA’s example regulation

on which the rule is based are archaic and do not reflect equipment

or practices that exist today; 2) it would be useful to better define the

term — affected area—, which appears throughout the rule; and 3)

the federal rule allows this rule to be limited to nonattainment area

boundaries, but the rule applies statewide. 

RESPONSE: The Missouri Department of Natural Resources is

required by 536.175, RSMo to review all department rules (Title 10

in the Code of State Regulations), including this rule, beginning July

1, 2016. Revisions to this rule may be proposed in the future as a

result of the rule review process. Regarding archaic elements of this

rule, the Air Pollution Control Program acknowledges that some of

the methods to meet emission reduction objectives in this rule may

be outdated. However, the emission reduction objectives in the rule

are based on and consistent with the federal example regulation. The

language in the proposed rulemaking clarifies that if the listed objectives are not applicable methods, the alert plan shall instead include

other applicable methods to achieve equivalent emission reductions

in the event of a purple alert or a maroon emergency alert. With

regard to the term — affected area —, the Missouri Air Conservation

Commission (MACC) or director is required by 643.090, RSMo to

protect the public’s health, safety, and welfare from emergency risk

levels of air contaminant buildup in any portion of the state making

the use of discretion necessary. Discretion is needed when determining specific portions of the state needing to be included in the affected area to assure it is protective of the public, which makes it impossible to define an affected area accurately in the rule. This same

statutory requirement also makes the retention of statewide applicability necessary. Retaining statewide applicability allows the MACC

or director discretion to address an air pollution purple alert or

maroon emergency alert appropriately in order to protect public

health, safety, or welfare of citizens across the entire state. It may be

necessary to take mitigation measures in an attainment area to

address a high air pollution episode occurring within the boundaries

of a nonattainment area. Since these alert levels have not occurred to

date, it is impossible to anticipate exact mitigation measures that will

be necessary to remedy any given situation. No changes have been

made to the rule text as a result of this comment.

10 CSR 10-6.130 Controlling Emissions During Episodes of High

Air Pollution Potential

(4) Reporting and Record Keeping. Facilities that are sources of air

contaminant emissions and required to file alert plans per Table C of

this rule shall file purple and maroon alert plans with the director

within sixty (60) days of the director’s request. Alert plans shall—

(A) Address the objectives provided in Tables D, E, and F; and

(B) Include the planning necessary for implementation. 

Updates to alert plans, including requests for rescissions, shall be

provided when changes to operations necessitate. 

Title 11—DEPARTMENT OF PUBLIC SAFETY

Division 45—Missouri Gaming Commission

Chapter 9—Internal Control System

ORDER OF RULEMAKING

By the authority vested in the Missouri Gaming Commission (MGC)

under section 313.805, RSMo Supp. 2013, the commission amends

a rule as follows:

11 CSR 45-9.106 Minimum Internal Control Standards (MICS)—

Chapter F is amended.

A notice of proposed rulemaking containing the text of the proposed

amendment was published in the Missouri Register on June 3, 2013

(38 MoReg 828). No changes have been made to the Minimum

Internal Control Standards (MICS) as incorporated by reference in

Chapter F. No changes have been made to the text of the proposed

amendment, so it is not reprinted here. This proposed amendment

becomes effective thirty (30) days after publication in the Code of

State Regulations. 

SUMMARY OF COMMENTS: A public hearing was held on this

proposed amendment on July 10, 2013. No one commented at the

public hearing. Mike Winter, Executive Director of the Missouri

Gaming Association submitted a written comment expressing support

for the removal of F §1.03 to allow patrons the ability to use electronic gaming devices as allowed in other gaming jurisdictions.

RESPONSE: The commission recognizes the removal of this section

places the options for the use of electronic devices with the licensees.

No changes have been made to this rule as a result of this comment.

Page 1828 Orders of Rulemaking
10 CSR 10-6.130 Controlling Emissions During Episodes of 

High Air Pollution Potential

(1) Applicability. 

 (A) This rule shall apply to all emissions from any source 

or from any premises sources and premises throughout 

the entire state with air emissions that contribute to 

sulfur dioxide (SO2), carbon monoxide (CO2), ozone (O3), 

nitrogen dioxide (NO2), or Particulate Matter—10 Micron 

(PM10) and 2.5 Micron (PM2.5). 

 (B) The boundaries of the affected area shall be determined 

at the discretion of the director in accordance with 

the nature and magnitude of the pollutant 

concentrations and meteorological conditions that cause 

the alert. 

(2) Definitions. Definitions of certain terms specified in this 

rule may be found in 10 CSR 10-6.020. 

(A) Air pollution alert — The level of an air pollution 

episode known as an air pollution alert is that condition 

when the concentration of air contaminants reach the level 

at which the first stage control actions are to begin. 

 (B) Air Stagnation Advisory — A special bulletin issued by 

the National Weather Service entitled “Air Stagnation 

Advisory,” which is used to warn air pollution control 

agencies that stagnant atmospheric conditions are 

expected which could cause increased concentrations of 

air contaminants near the ground. 

 (C) Area — For the purpose of this rule, any or all regions 

within the boundaries of the state of Missouri. 

 (D) Definitions of certain terms specified in this rule, 

other than those specified in this rule section, may be 

found in 10 CSR 10-6.020.

(3) General Provisions. 

 (A) Air Pollution Alerts. 

 1. The Air Quality Index shall be reported to the 

general public on a daily basis by all 
10 CSR 10-6.130 

2 

metropolitan statistical areas with a population 

exceeding three hundred fifty thousand (350,000). 

 2. Alert levels for applicable air pollutants are 

stated in terms of the Air Quality Index (AQI) as 

defined in 40 CFR part 58, Appendix G, for sulfur 

dioxide (SO2), carbon monoxide (CO), ozone (O3), 

nitrogen dioxide (NO2) and Particulate Matter—10 

Micron (PM10) and 2.5 Micron (PM2.5). Table A shows 

the relation of the AQI breakpoint values to 

equivalent concentrations of air contaminants. All 

concentrations are averaged over the time period 

indicated ranges to alert categories.

(1) Areas are generally required to report the AQI based on eight (8)-hour 

ozone values. However, there are a small number of areas where an AQI based 

on one (1)-hour ozone values would be more precautionary. In these cases, in 

addition to calculating the eight (8)-hour ozone index value, the one (1)-

hour ozone index value may be calculated, and the maximum of the two (2) 

values reported. 

(2) NO2 has no short-term National Ambient Air Quality Standard and can 

generate an AQI value only above two hundred (200). 

(3) Eight (8)-hour O3 values do not define higher AQI values (greater than or 

equal to three hundred one (301)). AQI values of three hundred one (301) or 

higher are calculated with one (1)-hour O3 concentrations.

 3. Alert types and levels of initiation. If an AQI 

value falls within the AQI range listed in Table A 

of this rule, the corresponding alert color shall 

be initiated.

 A. Orange alert AQI value. Any one (1) of the 

contaminants listed in paragraph (3)(A)2. 

reaching a concentration which results in an 

AQI value of one hundred one to one hundred 

fifty (101–150) shall initiate the orange 

alert. 

 B. Red alert AQI value. Any one (1) of the 

contaminants listed in paragraph (3)(A)2. 

reaching a concentration which results in an 

AQI value of one hundred fifty-one to two 

hundred (151–200) shall initiate the red 

alert. 

 C. Purple alert AQI value. Any one (1) of the 

contaminants listed in paragraph (3)(A)2. 

reaching a concentration which results in an 

AQI value of two hundred one to three hundred 

(201–300) shall initiate the purple alert. 

 D. Maroon emergency alert AQI value. Any one (1) 

of the contaminants listed in paragraph 

(3)(A)2. reaching a concentration which 

results in an AQI value of three hundred one 

to five hundred (301–500) shall initiate the 

maroon emergency alert. 

 4. Declaration of alerts. An orange alert, red alert, 

purple alert or maroon emergency alert may be 

declared on the basis of deteriorating air quality 

alone; an Air Stagnation Advisory need not be in 

effect. The appropriate episode status alert 

level should be declared by the director as 

ambient monitoring would indicate. 

 5. Termination of alerts. When, in the judgment of 

the director, meteorological conditions and 

pollutant concentrations warrant discontinuance of 

any alert condition, the director shall notify the 

technical staff, the chairman and members of the 

Missouri Air Conservation Commission that the 
10 CSR 10-6.130 

4 

alert has been discontinued and issue a public 

notice to that effect. 

 (B) Orange Alert Conditions. This subsection provides 

conditions that establish alert level categories. 

 1. Orange alert procedures shall be initiated by the 

director if the following conditions are met: 

 A. An Air Stagnation Advisory is in effect; 

 B. The orange alert AQI value is equaled or 

exceeded at any one (1) monitoring station 

within the affected area, unless there is a 

current forecast of meteorological 

improvement within the next twenty-four (24) 

hours; and 

 C. Meteorological conditions are such that the 

pollutant concentrations can be expected to 

remain or reoccur at the previously mentioned 

levels during the next twenty-four (24) or 

more hours or increase unless control actions 

are taken. 

 2. The following are orange alert procedures. The 

general public shall be informed through the news 

media that an orange alert exists, the 

geographical area(s) where the alert is 

applicable, the emission and type of source(s) 

that initiated the alert and encourage those with 

respiratory ailments or heart conditions to take 

the most appropriate and expedient precautions.

 2. The following are red alert procedures: 

 A. All affected governmental control agencies 

shall be notified that red alert conditions 

exist and that coordination of action is 

required; 

 B. All hospitals within the affected area shall 

be notified that red alert conditions exist; 

 C. The frequency of air monitoring shall be 

increased at all monitoring stations which 

are not continuous at intervals not exceeding 

one (1) hour, with continual hourly review at 

a central control location, if this equipment 

is available and it is deemed necessary by 

the director; 

 D. The general public shall be informed through 

the news media that a red alert exists, the 

geographical area(s) where the alert is 

applicable, the emission and type of 

source(s) that initiated the alert, 

individual abatement actions which will help 

alleviate the problem, and encourage those
