RE: Proposed Amendments to Minnesota’s State Implementation Plan to Incorporated Updated 

Minnesota Rules 

Dear Ms. Gade: 

Enclosed is a Minnesota State Implementation Plan (SIP) revision to revise and update 

Minnesota as included in Minnesota’s SIP. This SIP revision includes many changes to 

Minnesota’s air rules that have occurred over the past few years; it is intended to ensure that 

Minnesota’s SIP accurately reflects the current state of Minnesota’s air rules. It also includes a 

new rulemaking that makes the Clean Air Interstate Rule (CAIR) and Best Available Retrofit 

Technology (BART) applicable requirements for facilities. 

Most sections of Minnesota’s air rules have undergone changes, including sections on permits 

and certifications (Minn. Rules ch. 7001), permit fees (Minn. Rules ch. 7002), definitions and 

abbreviations (Minn. Rules ch. 7005), air emissions permits (Minn. Rules ch. 7007), offsets 

(Minn. Rules ch. 7007.4000), ambient air quality (Minn. Rules ch. 7009), standards for 

stationary sources (Minn. Rules ch. 7011), monitoring and testing requirements (Minn. Rules ch. 

7017), and emission inventory (Minn. Rules ch. 7019). 

All rule changes were made under the Minnesota Pollution Control Agency’s rulemaking 

authority and went through appropriate public participation procedures as required by state law. 

If you have any questions regarding this submittal, please contact Catherine Neuschler, of my 

staff, at 651-296-7774. 

Sincerely, 

Brad Moore

Background Information for SIP Revision 

To Update Minnesota’s Air Quality Rules Included in the Minnesota SIP 

This document provides background information on this State Implementation Plan (SIP) 

revision to recodify, refine and update Minnesota’s air quality rules into the Minnesota SIP. Most 

of Minnesota’s rules are included into the SIP as they stood in 1993 or 1994, and no later than 

1998. In the intervening years, many rules have been updated at least slightly. This has resulted 

in the rules that are included in Minnesota’s SIP by the EPA being out-of-date, which could 

result in inconsistent enforceability of rules at the State and Federal levels. 

This revision also includes some new rules related to implementation of the Clean Air Interstate 

Rule and Best Available Retrofit Technology. 

This SIP revision is being submitted to update Minnesota’s SIP at 40 CFR 52.1220 to accurately 

reflect Minnesota’s current rules, ensuring consistency between the State and Federal 

understandings of Minnesota’s air quality rules. 

Rules Update 

In the early 1990s, the MPCA submitted SIP revisions to incorporate various portions of 

Minnesota’s air rules into Minnesota’s SIP at 40 CFR 52.1220. Major submissions included 

submission of the Air Emission Permits Rule (Minn. R. 7007) in November 1993, in order to 

fulfill the requirements of the Title V program. Revisions to other portions of Minnesota’s rules 

were also submitted at that time. This revision was approved in May 1995 (60 FR 27411). 

In January 1995, the MPCA submitted a SIP revision to incorporate changes that had been made 

to the Air Emission Permits Rule and to Standards for Stationary Sources (Minn. R. 7011). This 

SIP revision was approved in May 1999 (64 FR 26880). 

An additional submittal was made in 1998 to incorporate changes to the Performance Test rule 

(Minn. R. 7017), and this was approved in 2002. No SIP revisions to incorporate changed rules 

have been made since that time; the most recent incorporation of rules into Minnesota’s SIP 

includes rules that were effective on the state level in July 1998. 

Through discussions with EPA Region V staff on making conditions in permits enforceable as 

SIP limitations, it was noted that the MPCA’s permit cover pages should state that, unless 

otherwise indicated, all state rules cited as the origin of permit terms are included in Minnesota’s 

SIP. Therefore, it is particularly important that the state rules be consistently represented at both 

the state and federal level. 

The MPCA therefore submits this SIP revision in order to ensure that Minnesota’s air quality 

rules are, where necessary, correctly included into Minnesota’s SIP. The changed rules do not 

adversely impact the ability of the SIP to protect Minnesota’s air quality, and in many cases 

strengthen the SIP. Therefore, the MPCA believes that all updated rules should be incorporated 

into the SIP.

Summary of Changes to Minnesota’s Air Rules 

This section lays out, in chronological order from oldest to most recent, many of the changes 

made to Minnesota’s air quality rules. Because of the length of time that has elapsed since many 

of the rulemakings, not all changes shown in Attachment 2 may be explained here. The MPCA 

has tried to provide summaries of the most crucial or largest rulemakings, while many minor rule 

changes and clarifications are not explained here. Additional information on any changes in the 

rules can be provided if needed. 

Rules are listed chronologically based on the date of publication of adoption in the State 

Register; the State Register citation is also provided. Summaries were developed by using the 

Statement of Need and Reasonableness (SONAR) prepared for each rulemaking as required by 

Minnesota procedures. 

The most recent changes made to Minnesota’s air quality rules are miscellaneous amendments 

made in 2007 through the “Multi-Rule.” 

Attachments to this SIP revision provide information on rule proposal and adoption. 

20 SR 2253 – Rules Governing Standards of Performance for Hot Mix Asphalt Plants 

In this 1995 rulemaking, the MPCA updated the performance standards for hot mix asphalt 

plants, amending all portions of the rule related to these plants (Minn. R. 7011.0900 – 0922.) 

The goals of the rulemaking were: 

• To ensure that the plants operate in a manner that minimizes their environmental impact 

• To regulate the industry efficiently, effectively, and fairly 

• Promote the use of less polluting plants, and 

• Streamline the ways in which plants show compliance. 

The major changes and additions to the performance standard were: 

1. Added operation, record keeping, and monitoring requirements for control equipment and 

dryer burners 

2. Outlined performance test frequency which is dependent on control equipment type 

3. Changed the opacity standard for existing plants to remove allowance of opacity 

excursions 

4. Listed materials allowed to be processed by plants 

5. Allowed small production throughput increases for all plants which test as less than 80% 

of their emission limit and additional increase for plants with baghouses whose tested 

emission rate is less than 50% of their emission limit. 

The rule also made asphalt plant eligible for registration permits, as all applicable requirements 

to ensure compliance from these facilities were listed in the rule. This required some minor 

changes to the registration permit rule in Minn. R. 7007. 
3

20 SR 2316 – Amendments to Chapters 7005, 7007, 7009, 7011 and 7017 

This was the first in a series of so-called “Omnibus” rulemakings to implement minor changes, 

clean ups, and clarifications to Minnesota’s air rules. This particular rulemaking was undertaken 

as a result of comments made on past rulemakings that could not be included in the previous 

rulemaking and to correct mistakes, clarify requirements, and address comments from industry, 

MPCA staff, and the EPA concerning corrections to be made to previously adopted rules. 

In Minn. R. 7005, clarifications were made to the appropriate definition and use of emission 

factors. In chapter 7007, changes were made to definitions and to clarify certain requirements 

such as which sources must obtain permits. Clarifications were also made to requirements for 

permit applications, permit content, registration permits, and reporting deviations from permit 

conditions. Chapter 7007 also included changes concerning calculations of fugitive emissions 

and others that generalized insignificant activities for particulate matter. 

In Chapter 7009, changes were made to streamline which facilities are required to prepare 

emission reduction plans and clarified the requirements for submitting these plans to the MPCA 

This rulemaking also included some changes to the listed control equipment and equipment 

efficiencies in Chapter 7011 that have since been further revised. The rulemaking also set forth 

the certifications to be included with performance test results in Chapter 7017. 

22 SR 1237 – Miscellaneous Amendments to Chapters 7005, 7007, 7009, 7011 and 7019 

The MPCA made rule amendments to Chapters 7005, 7007, 7009, 7011 and 7019 in order to 

clarify rule intent, change format to simplify interpretation, correct typographical errors, 

eliminate redundant or outdated requirements, correct conflicting requirements, account for new 

technology, eliminate overly burdensome requirements, streamline administrative procedures, 

and/or simplify implementation. This rulemaking also incorporated EPA suggestions for the 

MPCA’s operating permit program, namely clarification of the phrase “clarify a permit term” 

and the addition of a requirement that semi-annual deviation reporting occur regardless of 

whether a deviation had occurred. 

The more substantive changes made in this rulemaking include changes in Minn. R. 7007.0300, 

Sources Not Required to Obtain a Permit, that ensure sources are not subject to duplicative 

requirements such as requiring both a solid waste and an air permit for asbestos and to clarify 

language regarding recordkeeping and applicability for the permit exemption under this part. 

Changes to 7007.0750 also were made to clarify types of modification permits and to delete 

language in order to eliminate confusion about New Source Performance Standard modifications 

that are not subject to New Source Review. Language was also added to clarify the conditions 

under which there may be two-stage issuance of part 70 permits. Various other changes were 

added to clarify how to handle insignificant emissions and insignificant activities and how 

certain emission types or reductions should be handled in determining facility eligibility for 

permit types (such as registration permits.) 
4

The rulemaking also, in part 7007.1400, expanded the list of reasons that monitoring, record 

keeping or reporting requirements may be removed through administrative amendment to 

address problems in implementing the original rule. This includes easier removal of incorrect 

permit conditions or reporting requirements for units that have been permanently disabled. It 

also allows changes in valid test methods, inclusion of NESHAP requirements, and removal of 

conditions based entirely on repealed rules through administrative amendments, and explains 

what is considered clarification of a permit term. In 7009.0080, the MPCA removed the state 

ambient air quality standard for hydrocarbons as the standard was outdated. EPA rescinded the 

federal primary and secondary national ambient air quality standards (NAAQS) for hydrocarbons 

in 1983. The MPCA continues to regulate hydrocarbons as they apply to the ozone standard still 

listed in Chapter 7009 of the rules. 

Most other changes made in this rule were minor, relating to general clarification of the rules. 

23 SR 145 – Amendments to Rules Governing Standards of Performance for Opacity and 

Performance Tests, Minnesota Rules Chapter 7011 and 7017 

This rulemaking contained revisions to the performance test rule in Minn. R. 7017.2001 through 

7017.2060. The performance test rule was revised in order to address EPA comments and make 

the rule acceptable for incorporation into Minnesota’s SIP. This rulemaking was included into 

the SIP in 2002, but performance test rules have been subsequently amended as described below. 

23 SR 1764 – Amendments to Rules Governing Continuous Monitoring Systems (CMS), Minn. R. 

Ch 7017 

In this rulemaking, the MPCA made changes to Minnesota’s air rules governing the use of two 

types of CMS – Continuous Emission Monitoring Systems (CEMS) and Continuous Opacity 

Monitoring Systems (COMS). The rules adopted through this rulemaking are a fairly significant 

addition to what was originally submitted in the SIP. The original CEMS rule, 7017.1000, was 

repealed and replaced with a much longer and more detailed CMS rule which consolidated all 

CMS requirements. 

The goals of this rulemaking were to: 

1. Ensure the accuracy of CMS data by upgrading QA/QC requirements and requiring 

CMSs to be certified within a specified time period. 

2. Eliminate the need for CMS related permit attachments by incorporating all CMS 

requirements into the rule 

3. Reduce administrative burden on the regulated community by providing streamlined 

notification and reporting requirements; and 

4. Make the rule more user friendly by consolidating CMS requirements. 

Rule part 7017.1000 was repealed and replaced with more detailed CMS rules. The new rule 

lays out which facilities are required to install CMS and the various testing, installation, 

certification, operational and design requirements for the monitoring systems. It also delineates 

the recordkeeping and submittal requirements. The rule also has separate sections for CEMS and 
5

COMS. Because of the addition of the expanded CMS rule, certain performance test 

requirements relating to CEMs or CEMs certification and testing were removed in parts 

7017.2020, .2025, .2030, and .2090. 

23 SR 2224 – Proposed Miscellaneous Amendments to Air Quality Rules, chapters 7005 

(Definitions), 7007 (Permits), 7009 (Ambient Air Quality Standards), 7011 (Standards of 

Performance for Stationary Sources), 7019 (Reporting) and 7025 (Lead paint removal) 

This rulemaking was the second in a group of so-called “omnibus” rules updates to make 

changes that improve Minnesota’s air rules and yet were not significant enough to warrant 

individual rulemakings. The changes correct and improve rules to make them more 

understandable, up-to-date, and streamlined. Specifically, the rule amendments made in this 

rulemaking clarify rule intent, change format to simplify interpretation, correct typographical 

errors, eliminate redundant or outdated requirements, correct conflicting requirements, 

incorporate federal requirements into state rules, account for new technology, eliminate overly 

burdensome requirements, streamline administrative procedures, and simplify implementation. 

Some of the more major changes include changes to the definitions of “construction” and “begin 

actual construction” (and removal of the definition and term “commence”) for consistency with 

the EPA definition and in order to clarify what activities may occur prior to obtaining a permit 

and that initiation of reconstruction and modification activities are included in the term “begin 

actual construction.” Clarifying definitions were also made for “emission factor,” “block 

average,” “rolling average,” and “rolling sum.” This rulemaking allowed facilities to request 

state or general permits that expire more than 5 years after issuance in order to ensure that 

permits will be periodically updated (state permits generally do not expire). Simplified 

procedures for changes in ownership of a source with a general or registration permit were also 

included. Various other minor changes to the requirements for registration permits were also 

made, particularly to clarify compliance requirements and eligibility requirements and 

determination. The rules also clarify insignificant modifications, particularly in regards to 

hazardous air pollutants, detail which types of modifications require a permit amendment or 

written notification to the agency of the change, and clarify requirements for minor, moderate, 

and major permit amendments. 

This rulemaking also reflected changes to the ozone and PM2.5 NAAQS. In addition, changes 

were made to the control equipment titles in Chapter 7011, to define certain terms, add listed 

control equipment, and otherwise clarify requirements for control efficiency and control 

equipment operation and monitoring. These rule amendments repealed the state standards of 

performance for portland cement plants (Minn. R. 7011.0800), as there were no existing portland 

cement plants in the state and all new plants would be subject to the federal New Source 

Performance Standard (NSPS) incorporated by reference.

27 SR 1579 – New Rules Governing Conditionally Insignificant and Exempt Air Emissions (Ch. 

7008) and Amendments to Rules for Permits and Offsets (Ch. 7007) Definitions and 

Abbreviations (Ch. 7005) and Standards for Stationary Sources (Ch. 7011) 

This purpose of this rulemaking was to streamline and simplify the air quality permitting 

program by establishing conditions and consolidating regulations under which some facilities 

may avoid obtaining an air permit if they meet criteria intended to ensure that actual emissions 

(rather than potential emissions) do not exceed the threshold for obtaining a permit. This was 

done under the conditions laid out by EPA in the Potential to Emit (PTE) Guidance for Specific 

Source Categories issued in April 1998, stating that federal program requirements would be met 

if a state promulgated rules that would establish operating conditions that would ensure that 

emissions are less than 50% of the part 70 permitting threshold. 

This rulemaking established Minn. R. Ch. 7008 and established two new regulatory 

classifications: 

• Conditionally exempt stationary sources – Stationary sources that may avoid the 

requirement to obtain an air emission permit because they comply with the conditions set 

forth. 

• Conditionally insignificant activities – Activities or emission units that, if in compliance 

with the conditions set forth, may be insignificant activities for purposes of air emission 

permitting under Minnesota rules. 

The amendments to Chapter 7005 add definitions that are used in Chapters 7007, 7008, and 

7011. Chapter 7007 was amended to exempt sources that comply with Chapter 7008 from the 

requirement to obtain a permit and to treat conditionally insignificant activities the same way that 

insignificant activities are treated. Chapter 7011 was amended to move the permitting exemption 

for concrete manufacturing plants from 7011 to Chapter 7008 and to establish design and 

operation requirements for stage-one vapor recovery systems. 

28 SR 1482 – “Omnibus III” Rulemaking (2003) 

This rulemaking was the third in series of so-called “omnibus” rules designed to improve 

Minnesota’s air quality rules through clarifications and general updating. Examples of the kind 

of air quality rules included in this rulemaking are: the clarification of calculation procedures for 

permitting thresholds; removal of duplicative definitions; updating the definition of volatile 

organic compounds; and a change in the way that emissions inventory data is finalized. This rule 

also incorporated by reference, in Chapter 7011, several NESHAP standards promulgated by 

EPA in order to complete the MPCA’s acceptance of NESHAP delegation. 

Some specific and more substantive changes include allowing, under chapter 7007.0950, a 

concurrent start to the 30-day public comment period and the 45-day EPA review period for Title 

V permits or major modifications to such permits and to provide procedures for issuing permits 

under the concurrent review process and in the case of changes or EPA objections. 

Changes were also made in part 7007.0300 so that a facility subject only to the notification and 

recordkeeping requirements of a NSPS will not require a permit and changes in 7007.1110 to 
7

allow such facilities to apply for registration permits. The registration permit rule was also 

amended to allow facilities with registration permits to relocate to another area with minimal 

additional regulatory requirements if certain conditions are met. 

Changes were also made to the definition and application of insignificant activities in order to 

ensure that activities treated as insignificant due to control equipment remain insignificant; these 

were moved to a different rule chapter, Minn. R. 7008. 

29 SR 626 – Rule Governing Air Emission Permits (Minn.R. Ch 7007, with conforming 

amendments to Chapters 7011 and 7019. 

This rulemaking established a new option for the permitting of certain air emission facilities in 

the state, the “Capped Emission Permit,” open to facilities that have actual emissions less than or 

equal to 90 percent of the federal thresholds to obtain a permit to operate. These facilities are 

now able to apply for and obtain a permit in which the permit requirements are actually 

contained within the rule. This creates a hybrid permit option where all applicable requirements 

are applied by rule to non-complex facilities which do not need site-specific permit conditions, 

but provides for a public comment period on whether the facility should be eligible for the 

capped permit. In addition, although it allows for facilities to change their operations as long as 

they continue to meet the eligibility requirements for the capped permit, it requires the facility to 

show through analysis that they will remain under the emission caps and not contribute to 

ambient air violations after the change. Recordkeeping, reporting, monitoring, and emission 

inventory requirements are very similar to those placed in individual state permits. Facilities 

must track and calculate emissions on a monthly basis and must demonstrate that emissions 

beyond their property line are lower than the ambient standards. Capped permit do not expire 

unless the agency makes the permit expiring in order to promote continuing compliance. The 

capped permit rule is found in Minn. R. Chapter 7007.1140 through 1148. Other minor changes 

were also made throughout to accommodate this new permit rule. 

30 SR 1130 - Rules Relating to Repeal of Obsolete Rules 

In 2005, the MPCA repealed several obsolete rules that were still on the books. This included a 

change to Minnesota Rules chapter 7001, which establishes permits and certifications issued by 

the MPCA to regulate the following: hazardous waste facility permits; National Pollutant 

Discharge Elimination System permits; solid waste management facility permits; major facility 

substances storage permits and 401 certifications. 

Part 7001.0020 (Scope), item G, as currently in the SIP contains language governing mobile 

sources and indirect source permits for parking facilities; this part is obsolete as the rules 

governing indirect source permits were repealed by the Legislature in 2001. The MPCA retained 

in rules the remaining items listed in part 7001.0020, but these do not relate to air quality or air 

emission permits. 
8

Amendments to Rules Governing Air Quality Performance Standards, Air Emissions Permits, 

Emission Inventory Reporting and Miscellaneous Definitions and Incorporations by Reference in 

Minnesota Rules Chapters 7002, 7005, 7007, 7011, 7017 and 7019 

The most recent changes to the MPCA’s air quality rules are the “Multi-Rule” amendments, 

adopted on November 26, 2007. These rules update many portions of Minnesota’s air quality 

rules, and cover air quality performance standards, permits, emission inventory reporting, and 

miscellaneous definitions. The overall purpose of the rule amendments is to keep Minnesota’s 

air quality rules current with federal rules by removing redundant rule language, clarifying 

ambiguous language and correcting gaps or errors identified while administering the rules. In 

general this rulemaking involves updating definitions, incorporating new federal performance 

standards into state rules, and limited scope changes to state performance standards, emission 

inventory, performance testing, and permitting rules. 

The MPCA’s proposed changes to the control equipment rules, Minnesota Rules, parts 

7011.0060 to 7011.0080, represent a rule update with a broader scope. The MPCA’s intent is to 

update an existing elective rule so that it reflects modern day control assumptions and can 

potentially be utilized by more permittees to help them determine permit applicability. 

Additionally the new rules for regional haze, part 7007.5000, give the MPCA the authority to 

implement Best Available Retrofit Technology and other aspects of the federal regional haze 

program. The rule also adds the federal Clean Air Interstate Rule as an applicable requirement. 

The following table provides a summary of the rule changes occurring through the multi-rule. 

Rule Citation Change 

7002.0025, subp. 3 

Facilities failing to submit 

emissions inventories 

• Current rule relies on estimated actual emissions in permit application. 

Proposed change to rely on actual emissions in most recent inventory, if one 

was submitted. 

7005.0100 Definitions 

“emission factor” definition 

• Reflects inclusion of Hazardous Air Pollutants in EPA databases, removes 

obsolete AIRS database, and removes implied hierarchy of emission factor 

sources. 

7007.0100 Definitions 

“applicable requirement” 

definitions 

• Adds visibility related requirements established under CAA sections 169A or 

169B, and update EMS audit related definitions.

7007.1100 – 7007.1110

General permit and registration 

permit general requirements 

• Reduces eligibility for registration permit when a sector-specific general permit 

is available. Sand & gravel plants with registration permits must apply for 

general permit by Dec. 31 2008. Most sand & gravel plants already have a 

general permit, this levels playing field, promotes compliance; 

• Administrative update to EMS incorporation by reference; 

• Clarifies conditions under which a relocating source need not reapply for a 

registration permit and that this part does not apply to portable sources such as 

asphalt plants; 

• Clarifies a source may not obtain a registration permit if site-specific permit 

requirements are needed to ensure compliance or protect human health and the 

environment; 

• Expands conditions for agency to require an application for another type of 

permit such they are similar to those for the capped permit; 

• Adds NSPS subp. IIII (owner/operators of stationary compression ignition 

internal combustion engine < 30 liters/ cylinder) as an allowable NSPS

of the change. Non-expiring permit holders keep records for 5 years from date 

of change, expiring permit holders keep records until permit reissuance. 

7007.1250, subp. 3 

Insignificant modifications 

• Removes term “contemporaneous” as meaning is unclear. Requires that 

records of insignificant modifications be kept in accordance with 7007.1200, 

subp. 4. Current rule is silent on required duration of record keeping.

BART as soon as practicable but not later than 5 years after EPA approves 

Minnesota’s regional haze SIP. 

7011.0060-7011.0085 

Control Equipment Rule 

(Changed to focus on needs of 

registration and capped permit 

holders and to update control 

efficiencies) 

• Clarifies the rule is elective, i.e. the facility chooses to apply the default control 

efficiencies, monitoring and recordkeeping requirements. 

• Updates control efficiencies to generally reflect values compiled by contractor 

for various types of control 

• Reduces disincentives to use the rule by allowing registration permit holders to 

get 60% credit for control equipment venting through non-certified hoods. 

Retains 80% credit for venting through certified hoods for all permit types. 

• Capture efficiency for VOCs increased from 60 to 80% 

• Permittee given option to keep required control equipment monitoring records 

in paper or electronic copy. 

• Control credit added for PM and CO for listed VOC control devices. 

• Adds transition period with a requirement to apply for another type of permit 

by Dec. 31, 2008 if a facility used control equipment efficiencies and is no 

longer eligible for their permit type.

Emission Inventory 

• Adds ammonia as inventory pollutant. 

• Allows use of stack test data up to 10 years old. After 10 years, use higher of 

stack test results or default emission factor. 

• Increases allowable capture efficiency for VOC controls with hoods from 60 to 

80% 

Removal of Outdated Rules and Other Changes

With this SIP revision, the MPCA is requesting certain changes to the rules included in 

Minnesota’s SIP that are not documented above. 

As noted above, the scope of rule 7001 has been changed, and it now no longer explicitly 

references any air permits or air quality related requirements. Therefore, the MPCA is 

requesting removal of the previous provisions. 

The MPCA is requesting removal of Minnesota Rules 7023.1010 through 7023.1105, as they 

relate to a vehicle inspection program. These rules are no longer in existence, as they were 

determined to be obsolete and deleted or repealed by the legislature due to the end of the vehicle 

inspection program. The vehicle inspection program was terminated due to the Twin Cities’ 

attainment of the NAAQS for carbon monoxide. Therefore the MPCA also requests that 

Minnesota Statutes 116.60 through 116.65, which comprised the vehicle inspection program, be 

removed from the SIP. They were approved into the SIP with provisions stating that the 

inspection program would terminate once the area achieved the NAAQS for carbon monoxide. 

As the carbon monoxide NAAQS have been maintained, these rules are no longer necessary. 

The MPCA is also requesting removal of a large portion of the rules in Minn. R. 7011.1200, 

which relate to Standards of Performance for waste combustors. The rules as currently approved 

into the SIP have been repealed, and Minnesota’s new rules governing these sources have been 

submitted to EPA as a 111(d) plan and approved. Per previous discussions with EPA Region 5, 

these rules are not being submitted as part of the SIP.
