PART 18. PREVENTION OF SIGNIFICANT DETERIORATION OF AIR

QUALITY

R 336.2801 Definitions.

Rule 1801. The following definitions apply to terms used in this part. If a term defined

in this part is also defined elsewhere in the rules, then the definition contained here applies

for this part only.

(a) “Actual emissions” means the actual rate of emissions of a regulated new source

review pollutant from an emissions unit, as determined under R 336.1101(b), except that

this definition shall not apply for calculating whether a significant emissions increase has

occurred, or for establishing a plant wide applicability limit under R 336.2823. Instead,

the terms “projected actual emissions” and “baseline actual emissions” shall apply for those

purposes.

(b) “Baseline actual emissions” means the rate of emissions, in tons per year, of a

regulated new source review pollutant, as determined by the following:

(i) For any existing electric utility steam generating unit, baseline actual emissions

means the average rate, in tons per year, at which the unit actually emitted the pollutant

during any consecutive 24-month period selected by the owner or operator within the 5-

year period immediately preceding when the owner or operator begins actual construction

of the project. The department shall allow the use of a different time period upon a

determination that it is more representative of normal source operation. All of the

following provisions apply:

(A) The average rate shall include fugitive emissions to the extent quantifiable, and

emissions associated with startups, shutdowns, and malfunctions.

(B) The average rate shall be adjusted downward to exclude any noncompliant

emissions that occurred while the source was operating above an emission limitation that

was legally enforceable during the consecutive 24-month period.

(C) For a regulated new source review pollutant, if a project involves multiple

emissions units, then only 1 consecutive 24-month period shall be used to determine the

baseline actual emissions for the emissions units being changed. A different consecutive

24-month period may be used for each regulated new source review pollutant.

(D) The average rate shall not be based on any consecutive 24-month period for which

there is inadequate information for determining annual emissions, in tons per year, and for

adjusting this amount if required by paragraph (i)(B) of this subdivision.

(ii) For an existing emissions unit, other than an electric utility steam generating unit,

baseline actual emissions means the average rate, in tons per year, at which the emissions

unit actually emitted the pollutant during any consecutive 24-month period selected by the

owner or operator within the 10-year period immediately preceding either the date the

owner or operator begins actual construction of the project, or the date a complete permit

application is received by the department for a permit required by R 336.1201, whichever

is earlier, except that the 10-year period shall not include any period earlier than November

15, 1990. All of the following provisions apply:

(A) The average rate shall include fugitive emissions to the extent quantifiable, and

emissions associated with startups, shutdowns, and malfunctions.

(B) The average rate shall be adjusted downward to exclude any noncompliant

emissions that occurred while the source was operating above an emission limitation that

was legally enforceable during the consecutive 24-month period.

(C) The average rate shall be adjusted downward to exclude emissions that would have

exceeded an emission limitation with which the major stationary source must currently

comply, had such major stationary source been required to comply with such limitations

during the consecutive 24-month period. However, if an emission limitation is part of a

maximum achievable control technology standard that the United States environmental

protection agency proposed or promulgated under 40 C.F.R. part 63, adopted by reference

in R 336.1902, then the baseline actual emissions need only be adjusted if the state has

taken credit for such emissions reductions in an attainment demonstration or maintenance

plan submitted to the U.S. environmental protection agency.

(D) For a regulated new source review pollutant, if a project involves multiple

emissions units, then only 1 consecutive 24-month period shall be used to determine the

baseline actual emissions for the emissions units being changed. A different consecutive

24-month period may be used for each regulated new source review pollutant.

(E) The average rate shall not be based on any consecutive 24-month period for which

there is inadequate information for determining annual emissions, in tons per year, and for

adjusting this amount if required by subparagraphs (B) and (C) of this paragraph.

(iii) For a new emissions unit, the baseline actual emissions for purposes of determining

the emissions increase that will result from the initial construction and operation of such

unit shall equal zero; and thereafter, for all other purposes, shall equal the unit's potential

to emit.

(iv) For a plant wide applicability limit for a stationary source, the baseline actual

emissions shall be calculated for existing electric utility steam generating units under

paragraph (i) of this subdivision, for other existing emissions units under paragraph (ii) of

this subdivision, and for a new emissions unit under paragraph (iii) of this subdivision.

(c) “Baseline area” means all of the following:

(i) Any intrastate area, and every part thereof, designated as attainment or unclassifiable

under section 107(d) of the clean air act in which the major source or major modification

establishing the minor source baseline date would construct or would have an annual

average air quality impact equal to or greater than 1 microgram per cubic meter for sulfur

dioxide, oxides of nitrogen, or PM-10, or 0.3 microgram per cubic meter for PM 2.5 of the

pollutant for which the minor source baseline date is established.

(ii) Area redesignations under section 107(d) of the clean air act shall not intersect or be

smaller than the area of impact of any major stationary source or major modification which

does either of the following:

(A) Establishes a minor source baseline date.

(B) Is subject to PSD regulations or new source review for major sources in

nonattainment areas regulations.

(iii) Any baseline area established originally for the total suspended particulates

increments shall remain in effect and shall apply for purposes of determining the amount

of available PM-10 increments, except that the baseline area shall not remain in effect if

the department rescinds the corresponding minor source baseline date under subdivision

(bb)(iv) of this rule.

(d) “Baseline concentration” means the value derived using the following procedures:

(i) The ambient concentration level that exists in the baseline area at the time of the

applicable minor source baseline date. A baseline concentration is determined for each

pollutant for which a minor source baseline date is established and shall include both of

the following:

(A) The actual emissions representative of sources in existence on the applicable minor

source baseline date.

(B) The allowable emissions of major stationary sources that commenced construction

before the major source baseline date, but were not in operation by the applicable minor

source baseline date.

(ii) The following shall not be included in the baseline concentration and shall affect the

applicable maximum allowable increase:

(A) Actual emissions from any major stationary source on which construction

commenced after the major source baseline date.

(B) Actual emissions increases and decreases at any stationary source occurring after

the minor source baseline date.

(e) “Begin actual construction” means, in general, initiation of physical on-site

construction activities on an emissions unit which are of a permanent nature. Such

activities include, but are not limited to, installation of building supports and foundations,

laying of underground pipework, and construction of permanent storage structures. “A

change in method of operation” refers to those on-site activities, other than preparatory

activities, which mark the initiation of the change.

(f) “Best available control technology” or “BACT” means an emissions limitation,

including a visible emissions standard, based on the maximum degree of reduction for each

regulated new source review pollutant, which would be emitted from any proposed major

stationary source or major modification which the department -- on a case-by-case basis,

taking into account energy, environmental, and economic impacts and other costs --

determines is achievable for such source or modification through application of production

processes or available methods, systems, and techniques, including fuel cleaning or

treatment or innovative fuel combination techniques for control of the pollutant.

Application of best available control technology shall not result in emissions of any

pollutant which would exceed the emissions allowed by any applicable standard under 40

C.F.R. parts 60 and 61, adopted by reference in R 336.1902. If the department determines

that technological or economic limitations on the application of measurement methodology

to a particular emissions unit would make the imposition of an emissions standard

Page 3

infeasible, then a design, equipment, work practice, operational standard, or combination

thereof, may be prescribed instead to satisfy the requirement for the application of best

available control technology. The standard shall, to the degree possible, set forth the

emissions reduction achievable by implementation of the design, equipment, work

practice, or operation, and shall provide for compliance by means which achieve equivalent

results.

(g) “Building, structure, facility, or installation” means all of the pollutant-emitting

activities which belong to the same industrial grouping, are located on 1 or more contiguous

or adjacent properties, and are under the control of the same person, or persons under

common control, except the activities of any vessel. Pollutant-emitting activities are part

of the same industrial grouping if they have the same 2-digit major group code associated

with their primary activity. Major group codes and primary activities are described in the

standard industrial classification manual, 2017.

(h) “Clean coal technology” means any technology, including technologies applied at the

pre-combustion, combustion, or post-combustion stage, at a new or existing facility which

will achieve significant reductions in air emissions of sulfur dioxide or oxides of nitrogen

associated with the utilization of coal in the generation of electricity, or process steam

which was not in widespread use as of November 15, 1990.

(i) “Clean coal technology demonstration project” means a project using funds

appropriated under the heading "Department of Energy -- Clean Coal Technology," up to

a total amount of $2,500,000,000 for commercial demonstration of clean coal technology,

or similar projects funded through appropriations for the United States Environmental

Protection Agency. The federal contribution for a qualifying project shall be at least 20%

of the total cost of the demonstration project.

modification, means that the owner or operator has all necessary preconstruction approvals

or permits and has done either of the following:

(i) Begun, or caused to begin, a continuous program of actual on-site construction of the

source, to be completed within a reasonable time.

(ii) Entered into binding agreements or contractual obligations, which cannot be

canceled or modified without substantial loss to the owner or operator, to undertake a

program of actual construction of the source to be completed within a reasonable time.

(l) “Complete” means, in reference to an application for a permit, that the application

contains all the information necessary for processing the application. Designating an

application complete for purposes of permit processing does not preclude the department

from requesting or accepting additional information.

(m) “Construction” means any physical change or change in the method of operation,

including fabrication, erection, installation, demolition, or modification of an emissions

unit, that would result in a change in emissions.

(n) “Continuous emissions monitoring system” or “CEMS” means all of the equipment

that may be required to meet the data acquisition and availability requirements of these

rules, to sample, condition if applicable, analyze, and provide a record of emissions on a

continuous basis.

necessary to meet the data acquisition and availability requirements of these rules, to

monitor process and control device operational parameters (for example, control device

secondary voltages and electric currents) and other information (for example, gas flow rate,

oxygen or carbon dioxide concentrations), and to record average operational parameter

value or values on a continuous basis.

(q) “Electric utility steam generating unit” means any steam electric generating unit that

is constructed for supplying more than 1/3 of its potential electric output capacity and more

than 25 megawatt electrical output to any utility power distribution system for sale. Steam

supplied to a steam distribution system for providing steam to a steam-electric generator

that would produce electrical energy for sale is also considered in determining the electrical

energy output capacity of the affected facility.

(r) “Emissions unit” means any part of a stationary source that emits or would have the

potential to emit any regulated new source review pollutant and includes an electric utility

steam generating unit. Both of the following are types of emissions units:

(i) A new emissions unit is any emissions unit that is, or will be, newly constructed and

that has existed for less than 2 years from the date the emissions unit first operated.

(ii) An existing emissions unit is any emissions unit that does not meet the definition of

a new emissions unit. A replacement unit is an existing emissions unit and no creditable

emission reductions shall be generated from shutting down the existing emissions unit that

is replaced. A replacement unit shall meet all of the following criteria:

(A) The emissions unit is a reconstructed unit if the replacement of components of an

existing facility is to such an extent that the fixed capital cost of the new components

exceeds 50% of the fixed capital cost that would be required to construct a comparable

entirely new facility or the emissions unit completely takes the place of an existing

emissions unit.

(B) The emissions unit is identical to or functionally equivalent to the replaced

emissions unit.

(C) The replacement does not alter the basic design parameters of the process unit.

(D) The replaced emissions unit is permanently removed from the major stationary

source, otherwise permanently disabled, or permanently barred from operation by a permit

that is enforceable as a practical matter. If the replaced emissions unit is brought back into

operation, it shall constitute a new emissions unit.

(s) “Federal land manager” means, with respect to any lands in the United States, the

secretary of the department with authority over such lands.

(t) “High terrain” means an area having an elevation 900 feet or more above the base of

after a reasonable shakedown period, not to exceed 180 days.

(viii) The definition of actual emissions in R 336.1101(b) shall not apply for determining

creditable increases and decreases after a change, instead the definitions of the terms

“projected actual emissions” and “baseline emissions” shall be used.

(ff) [Reserved]

(gg) “Pollution prevention” means any activity that through process changes, product

reformulation or redesign, or substitution of less polluting raw materials, eliminates or

mean recycling, other than certain "in-process recycling" practices, energy recovery,

treatment, or disposal.

(hh) “Potential to emit” means the maximum capacity of a stationary source to emit a

pollutant under its physical and operational design. A physical or operational limitation on

the capacity of the source to emit a pollutant, including air pollution control equipment and

period) following the date the unit resumes regular operation after the project, or in any 1

of the 10 years following that date, if the project involves increasing the emissions unit's

design capacity or its potential to emit that regulated new source review pollutant, and full

utilization of the unit would result in a significant emissions increase, or a significant net

actual emissions and that are also unrelated to the particular project, including any

increased utilization due to product demand growth.

(iii) The owner or operator of a major stationary source may use the emissions unit's

potential to emit, in tons per year, instead of calculating projected actual emissions.

(mm) “Reactivation of a very clean coal-fired electric utility steam generating unit” means

R 336.2802 Applicability.

Rule 1802. (1) This part applies to the construction of a new major stationary source or

a project at an existing major stationary source in an area designated as attainment or

unclassifiable under sections 107(d)(1)(A)(ii) or (iii) of the clean air act.

(2) The requirements of R 336.2810 to R 336.2818 apply to the construction of any new

major stationary source or the major modification of any existing major stationary source,

except as this rule otherwise provides.

(3) No new major stationary source or major modification to which R 336.2810 to

R 336.2818(2) apply shall begin actual construction without a permit to install issued under

R 336.1201(1)(a) that states that the major stationary source or major modification will

meet those requirements.

(4) This part applies to the construction of new major sources and major modifications to

existing major sources in the following manner:

(a) Except as otherwise provided in subrule (5) of this rule, and consistent with the

definition of major modification, a project is a major modification for a regulated new

source review pollutant if it causes both of the following types of emissions increases:

(i) A significant emissions increase.

(ii) A significant net emissions increase.

The project is not a major modification if it does not cause a significant emissions increase.

If the project causes a significant emissions increase, then the project is a major

modification only if it also results in a significant net emissions increase.

(b) The procedure for calculating whether a significant emissions increase will occur

depends upon the type of emissions units being modified. The procedure for calculating

whether a significant net emissions increase will occur at the major stationary source is

contained in the definition of net emissions increase. Regardless of preconstruction

projections, a major modification results if the project causes a significant emissions

increase and a significant net emissions increase.

(c) The actual-to-projected-actual applicability test may be used for projects that only

involve existing emissions units. A significant emissions increase of a regulated new

source review pollutant is projected to occur if the sum of the difference between the

Page 13

Courtesy of Michigan Administrative Rules

projected actual emissions and the baseline actual emissions for each existing emissions

unit equals or exceeds the significant amount for that pollutant.

(d) The actual-to-potential test may be used for projects that involve construction of new

emission units or modification of existing emission units. A significant emissions increase

of a regulated new source review pollutant is projected to occur if the sum of the difference

between the potential to emit from each new or modified emission unit following

completion of the project and the baseline actual emissions of these units before the project

equals or exceeds the significant amount for that pollutant.

(e) The hybrid test may be used for projects that involve multiple types of emissions

units. A significant emissions increase of a regulated new source review pollutant is

projected to occur if the sum of the emissions increases for each emissions unit, using the

appropriate methods specified in this subrule as applicable with respect to each emissions

unit, for each type of emissions unit equals or exceeds the significant amount for that

pollutant.

(5) For any major stationary source with a plant wide applicability limit for a regulated

new source review pollutant, the major stationary source shall comply with R 336.2823.

(2) If an applicant submits a permit application to the department for a proposed major

stationary source or major modification that affects a federal class I area, the applicant must

submit to the department and the federal land manager charged with direct responsibility

for management of class I lands a demonstration of the impact the emissions from the

proposed source or modification would have on the air quality related values of class I

lands, including visibility. The department shall be available to consult with and provide

additional information to the federal land manager during the federal land manager’s

review of the demonstration submitted by the applicant, if necessary, to complete the

review of the demonstration.

(3) If the federal land manager’s review of the applicant’s demonstration results in a

finding that the emissions from the proposed major source or major modification would

have an adverse impact on the air quality related values of class I areas, including visibility,

notwithstanding that the change in air quality resulting from emissions from a major source

or major modification would not cause or contribute to concentrations that would exceed

the maximum allowable increases for a class I area, and if the department concurs with

such finding, then the department shall not approve the permit application.

(4) If the department determines that the emissions from a proposed major source or major

modification would cause or contribute to concentrations which would exceed the

maximum allowable increases for a class I area, the department shall not approve a permit

application unless the applicable requirements of Michigan’s state implementation plan are

otherwise met and 1 of the following occurs:

(a) The applicant submits a written certification that the applicant has demonstrated to

the federal land manager that the emissions from the proposed major source or major

modification would have no adverse impact on the air quality related values of class I lands,

including visibility, notwithstanding that the change in air quality resulting from emissions

from a major source or major modification would cause or contribute to concentrations that

would exceed the maximum allowable increases for a class I area. The department may

then, provided that applicable requirements are otherwise met, issue the permit with

emission limitations to assure that emissions of sulfur dioxide, particulate matter, and

oxides of nitrogen would not exceed the following maximum allowable increases over

minor source baseline concentration for the pollutants:

(b) If the department cannot approve the permit application under R 336.2816(4)(a) due

to sulfur dioxide emissions resulting in increases greater than those specified in table 183

for periods of 24 hours or less, the applicant may obtain approval by providing a written

certification that the applicant has demonstrated to the federal land manager that the

emissions from the proposed major source or major modification would have no adverse

impact on the air quality related values of class I lands, including visibility, and that both

the governor and the federal land manager have granted a sulfur dioxide variance for the

federal class I area on which variance the public has received notice and opportunity for

public hearing.

(c) If the department cannot approve the permit application under R 336.2816(4)(a) due

to sulfur dioxide emissions resulting in increases greater than those specified in table 183

for periods of 24 hours or less, and the department cannot approve the permit application

under R 336.2816(4)(b) because the federal land manager does not concur with the

governor’s issuance of a sulfur dioxide variance that is otherwise consistent with R

336.2816(4)(b), the applicant may obtain approval by providing a written certification that

the applicant has demonstrated to the president that a sulfur dioxide variance is in the

national interest and the president concurs with the issuance of the sulfur dioxide variance

by the governor. The applicant shall transfer the recommendations of the governor and the

federal land manager to the president in any case where the governor recommends a

variance in which the federal land manager does not concur.

(5) The department will not issue a permit affecting a class I area in which a sulfur dioxide

variance was granted under R 336.2816(4)(b) or (c), unless the permit includes emission

limitations necessary to assure that emissions of sulfur dioxide from the major source or

major modification would not, during any day on which the otherwise applicable maximum

allowable increases are exceeded, cause or contribute to concentrations which would

exceed the following maximum allowable increases over the baseline concentration and to

assure that emissions would not cause or contribute to concentrations which exceed the

otherwise applicable maximum allowable increases for periods of exposure of 24 hours or

less for more than 18 days, not necessarily consecutive, during any annual period.

R 336.2818 Source obligation.

Rule 1818. (1) Approval to construct shall not relieve an owner or operator of the

responsibility to comply fully with applicable provisions of the state implementation plan

and any other requirements under local, state, or federal law.

Page 24

(2) If a particular major source or major modification becomes a major stationary source

or major modification solely by virtue of a relaxation in any enforceable limitation which

was established after August 7, 1980, on the capacity of the major source or major

modification otherwise to emit a pollutant, such as a restriction on hours of operation, then

the requirements of R 336.2810 to R 336.2819 shall apply to the major source or major

modification as though construction had not yet commenced on the major source or major

modification.

(3) All of the following provisions apply to any regulated new source review pollutant

emitted from projects at existing emissions units at a major stationary source, other than

projects at a major source with a plant wide applicability limit, where there is a reasonable

possibility, as defined in R 336.2818(3)(f), that a project that is not a part of a major

modification may result in a significant emissions increase of such pollutant, and the owner

or operator elects to use the method specified in R 336.2801(ll)(ii)(A) to (C) for calculating

projected actual emissions:

(a) Before beginning actual construction of the project, the owner or operator shall

document and maintain a record of all of the following information:

(i) A description of the project.

(ii) Identification of the emissions unit or units whose emissions of a regulated new major

source review pollutant may be affected by the project.

(iii) A description of the applicability test used to determine that the project is not a major

modification for any regulated new source review pollutant, including the baseline actual

emissions, the projected actual emissions, the amount of emissions excluded under R

336.2801(ll)(ii)(C) and an explanation for why such amount was excluded, and any netting

calculations, if applicable.

(b) If the emissions unit is an existing electric utility steam generating unit, then before

beginning actual construction, the owner or operator shall provide a copy of the

information required by subdivision (a) of this subrule to the department. This subdivision

does not require the owner or operator

of the unit to obtain any determination from the department before beginning actual

construction.

(c) The owner or operator shall monitor the emissions of a regulated new source review

pollutant that could increase as a result of the project and that is emitted by any emissions

unit identified in subdivision (a)(ii) of this subrule; and calculate and maintain a record of

the annual emissions, in tons per year on a calendar year basis, for a period of 5 years

following resumption of regular operations after the change, or for a period of 10 years

following resumption of regular operations after the change if the project increases the

design capacity or potential to emit of that regulated new major source review pollutant at

the emissions unit.

(d) If the unit is an existing electric utility steam generating unit, then the owner or operator

shall submit a report to the department within 60 days after the end of each year during

which records are generated under subdivision (c) of this subrule setting out the unit's

annual emissions during the calendar year before submission of the report.

(e) If the unit is an existing unit other than an electric utility steam generating unit, then

the owner or operator shall submit a report to the department if the annual emissions, in

tons per year, from the project exceed the baseline actual emissions by a significant amount

for that regulated new source review pollutant, and if such emissions differ from the

Page 25

preconstruction projection. The owner or operator shall submit the report to the department

within 60 days after the end of such year. The report shall contain all of the following:

(i) The name, address, and telephone number of the major stationary source.

(ii) The annual emissions as calculated under subdivision (c) of this subrule.

(iii) Any other information that the owner or operator wishes to include in the report; for

example, an explanation as to why the emissions differ from the preconstruction projection.

(f) A reasonable possibility occurs when the owner or operator calculates the project to

result in either of the following:

(i) A projected actual emissions increase of at least 50% of the amount that is a significant

emissions increase, as defined in R 336.2801(rr), without reference to the amount that is a

significant net emissions increase for the regulated new source review pollutant.

(ii) A projected actual emissions increase that, added to the amount of emissions excluded

under R 336.2801(ll)(ii)(C), sums to at least 50% of the amount that is a significant

emissions increase, as defined in R 336.2801(rr), without reference to the amount that is a

significant net emissions increase for the regulated new source review pollutant. For a

project for which a reasonable possibility occurs only within the meaning of R

336.2818(3)(f)(ii), and not also within the meaning of R 336.2818(3)(f)(i), then the

provisions of R 336.2818(3)(b) to (e) do not apply to the project.

(4) The owner or operator of the major source shall make the information required to be

documented and maintained under this rule available for review upon request for inspection

by the department or the general public under MCL 324.5516(2).

R 336.2819 Innovative control technology.

Rule 1819. (1) An owner or operator of a proposed major stationary source or major

modification may request the department to approve a system of innovative control

technology.

(2) The department may, with notice to and advice from each affected state, determine that

the major source or major modification may employ a system of innovative control

technology, if all of the following occurs:

(a) The proposed control system would not cause or contribute to an unreasonable risk to

public health, welfare, or safety in its operation or function.

(b) The owner or operator agrees to achieve a level of continuous emissions reduction

equivalent to that which would have been required by R 336.2810(2), by a date specified

by the department. The date shall not be later than 4 years from the time of startup or 7

years from permit issuance.

(c) The major source or major modification would meet the requirements equivalent to

those in R 336.2810 and R 336.2811, based on the emissions rate that the major stationary

source employing the system of innovative control technology would be required to meet

on the date specified by the department.

(d) The major source or major modification would not do either of the following before

the date specified by the department:

(i) Cause or contribute to any violation of an applicable national ambient air quality

standard.

(ii) Impact any area where an applicable increment is known to be violated.

Page 26

(e) All other applicable requirements including those for public participation have been

met.

(f) The provisions of R 336.2816, relating to class I areas, have been satisfied with respect

to all periods during the life of the major source or major modification.

(3) The department shall withdraw an approval to employ a system of innovative control

technology made under this rule, if any of the following occurs:

(a) The proposed system fails by the specified date to achieve the required continuous

emissions reduction rate.

(b) The proposed system fails before the specified date so as to contribute to an

unreasonable risk to public health, welfare, or safety.

(c) The department decides at any time that the proposed system is unlikely to achieve the

required level of control or to protect the public health, welfare, or safety.

(4) If a major source or major modification fails to meet the required level of continuous

emissions reduction within the specified time period, or if the approval is withdrawn under

subrule (3) of this rule, then the department may allow the major source or major

modification up to an additional 3 years to meet the requirement for the application of best

available control technology through use of a demonstrated system of control.

R 336.2823 Actuals plantwide applicability limits (PALs).

Rule 1823. (1) The following definitions apply to the use of actuals PALs consistent with

this rule. If a term is not defined in these paragraphs, it shall have the meaning given in R

336.2801 or R 336.1101 to R 336.1127.

(a) "Actuals PAL for a major stationary source" means a PAL based on the baseline

actual emissions of all emissions units at the major source that emit or have the potential

to emit the PAL pollutant.

(b) "Allowable emissions" means allowable emissions as defined in R 336.2801, except

as this definition is modified by the following:

(i) The allowable emissions for any emissions unit shall be calculated considering any

emission limitations that are enforceable as a practical matter on the emissions unit's

potential to emit.

(ii) An emissions unit's potential to emit shall be determined using the definition in

R 336.2801, except that the words "or enforceable as a practical matter" should be added

after "federally enforceable."

(c) "Small emissions unit" means an emissions unit that emits or has the potential to emit

the PAL pollutant in an amount less than the significant level for that PAL pollutant, as

defined in R 336.2801 or in the clean air act, whichever is lower.

(d) "Major emissions unit" means either of the following:

(i) Any emissions unit that emits or has the potential to emit 100 tons per year or more

of the PAL pollutant in an attainment area.

(ii) Any emissions unit that emits or has the potential to emit the PAL pollutant in an

amount that is equal to or greater than the major source threshold for the PAL pollutant as

defined by the clean air act for nonattainment areas.

Page 27

Courtesy of Michigan Administrative Rules

(e) "Plantwide applicability limitation" or "PAL" means an emission limitation

expressed in tons per year, for a pollutant at a major stationary source, that is enforceable

as a practical matter and established source-wide in accordance with this rule.

(f) "PAL effective date" means the date of issuance of the PAL permit. However, the

PAL effective date for an increased PAL is the date any emissions unit that is part of the

PAL major modification becomes operational and begins to emit the PAL pollutant.

(g) "PAL effective period" means the period beginning with the PAL effective date and

ending 10 years later.

(h) "PAL major modification" means, notwithstanding the definitions for major

modification and net emissions increase, any physical change in or change in the method

of operation of the PAL major source that causes it to emit the PAL pollutant at a level

equal to or greater than the PAL.

(i) "PAL permit" means the permit to install issued under R 336.1201(1)(a)

or R 336.1214a that establishes a PAL for a major stationary source.

(j) "PAL pollutant" means the pollutant for which a PAL is established at a major

stationary source.

(k) "Significant emissions unit" means an emissions unit that emits or has the potential

to emit a PAL pollutant in an amount that is equal to or greater than the significant level,

as defined in R 336.2801 or in the clean air act, whichever is lower, for that PAL pollutant,

but less than the amount that would qualify the unit as a major emissions unit.

(2) The following provisions describe the applicability of other federal regulations to

major sources with PALs:

(a) The department may approve the use of an actuals PAL for any existing major

stationary source if the PAL meets all of the requirements of this rule. The term "PAL"

shall mean "actuals PAL" in this rule.

(b) Any physical change in or change in the method of operation of a major stationary

source that maintains its total source-wide emissions below the PAL level, meets the

requirements of this rule, and complies with the PAL permit. If the change complies with

the PAL permit, then the following statements apply:

(i) The change is not a major modification for the PAL pollutant.

(ii) The change does not have to otherwise be approved under prevention of significant

deterioration of air quality regulations or new source review for major sources in

nonattainment areas regulations.

(iii) The change is not subject to R 336.2818(2), restrictions on relaxing enforceable

emission limitations that the major stationary source used to avoid applicability of the

major new source review program.

(c) Except as provided under subdivision (b)(iii) of this subrule, a major stationary

source shall continue to comply with all applicable federal or state requirements, emission

limitations, and work practice requirements that were established before the effective date

of the PAL.

(3) As part of a permit application requesting a PAL, the owner or operator of a major

stationary source shall submit the following information to the department for approval:

(a) A list of all emissions units at the major source designated as small, significant, or

major based on their potential to emit. In addition, the owner or operator of the major

source shall indicate which, if any, federal or state applicable requirements, emission

limitations, or work practices apply to each unit.

Page 28

(b) Calculations of the baseline actual emissions with supporting documentation.

Baseline actual emissions shall include emissions associated not only with operation of the

unit, but also emissions associated with startup, shutdown, and malfunction.

(c) The calculation procedures that the major stationary source owner or operator

proposes to use to convert the monitoring system data to monthly emissions and annual

emissions based on a 12-month rolling total for each month as required by subrule (13)(a)

of this rule.

(4) The following requirements establish PALs:

(a) The department may establish a PAL at a major stationary source, provided that, at a

minimum, the following requirements are met:

(i) The PAL shall impose an annual emission limitation in tons per year, that is

enforceable as a practical matter, for the entire major stationary source. For each month

during the PAL effective period after the first 12 months of establishing a PAL, the major

stationary source owner or operator shall show that the sum of the monthly emissions from

each emissions unit under the PAL for the previous 12 consecutive months is less than the

PAL, a 12-month average rolled monthly. For each month during the first 11 months from

the PAL effective date, the major stationary source owner or operator shall show that the

sum of the preceding monthly emissions from the PAL effective date for each emissions

unit under the PAL is less than the PAL.

(ii) The PAL shall be established in a PAL permit that meets the public participation

requirements in subrule (5) of this rule.

(iii) The PAL permit shall comply with subrule (7) of this rule.

(iv) The PAL shall include fugitive emissions, to the extent quantifiable, from all

emissions units that emit or have the potential to emit the PAL pollutant at the major

stationary source.

(v) Each PAL shall regulate emissions of only 1 pollutant.

(vi) Each PAL shall have a PAL effective period of 10 years.

(vii) The owner or operator of the major stationary source with a PAL shall comply

with the monitoring, recordkeeping, and reporting requirements provided in subrules (12)

to (14) of this rule for each emissions unit under the PAL through the PAL effective period.

(b) Emissions reductions of a PAL pollutant that occur during the PAL effective period

are not creditable as decreases for emissions offsets unless the level of the PAL is reduced

by the amount of the emissions reductions and the reductions would be creditable in the

absence of the PAL.

(5) PALs for existing major stationary sources shall be established, renewed, or increased,

through a permit to install issued under R 336.1201(1)(a). The department shall provide

the public with notice of the proposed approval of a PAL permit and at least a 30-day period

for submittal of public comment. The department shall address all material comments

before taking final action on the permit.

(6) The following apply to setting the 10-year actuals PAL level:

(a) Except as provided in subdivision (b) of this subrule, the actuals PAL level for a

major stationary source shall be established as the sum of the baseline actual emissions of

the PAL pollutant for each emissions unit at the major source; plus an amount equal to the

applicable significant level for the PAL pollutant as defined in R 336.2801 or the clean air

act, whichever is lower. When establishing the actuals PAL level, for a PAL pollutant,

only 1 consecutive 24-month period shall be used to determine the baseline actual

Page 29

Courtesy of Michigan Administrative Rules

emissions for all existing emissions units. However, a different consecutive 24-month

period may be used for each different PAL pollutant. Emissions associated with units that

were permanently shut down after this 24-month period shall be subtracted from the PAL

level. The department shall specify a reduced PAL level, in tons per year, in the PAL

permit to become effective on the future compliance dates of any applicable federal or state

regulatory requirement before issuance of the PAL permit. For example, if the major

source owner or operator will be required to reduce emissions from industrial boilers in

half from baseline emissions of 60 parts per million oxides of nitrogen to a new rule limit

of 30 parts per million, then the permit shall contain a future effective PAL level that is

equal to the current PAL level reduced by half of the original baseline emissions of the

units.

(b) For newly constructed units, which do not include modifications to existing units, on

which actual construction began after the 24-month period, instead of adding the baseline

actual emissions as specified in subdivision (a) of this subrule, the emissions shall be added

to the PAL level in an amount equal to the potential to emit of the units.

(7) The PAL permit shall contain, at a minimum, all of the following information:

(a) The PAL pollutant and the applicable source-wide emission limitation in tons per

year.

(b) The PAL permit effective date and the expiration date of the PAL (PAL effective

period).

(c) Specification in the PAL permit that if a major stationary source owner or operator

applies to renew a PAL under subrule (10) of this rule before the end of the PAL effective

period, then the PAL shall not expire at the end of the PAL effective period. It shall remain

in effect until a revised PAL permit is issued by the department.

(d) A requirement that emission calculations for compliance purposes include emissions

from startups, shutdowns, and malfunctions.

(e) A requirement that, once the PAL expires, the major stationary source is subject to

subrule (9) of this rule.

(f) The calculation procedures that the major stationary source owner or operator shall

use to convert the monitoring system data to monthly emissions and annual emissions

based on a 12-month rolling total for each month as required by subrule (3)(a) of this rule.

(g) A requirement that the major stationary source owner or operator monitor all

emissions units in accordance with the provisions under subrule (13) of this rule.

(h) A requirement to retain the records required under subrule (13) of this rule on site.

The records may be retained in an electronic format.

(i) A requirement to submit the reports required under subrule (14) of this rule by the

required deadlines.

(j) Any other requirements that the department determines necessary to implement and

enforce the PAL.

(8) All of the following apply to the PAL effective period and reopening of the PAL

permit:

(a) The department shall specify a PAL effective period of 10 years.

(b) All of the following apply to reopening of the PAL permit.

(i) During the PAL effective period, the department shall reopen the PAL permit to do

any of the following:

Page 30

Courtesy of Michigan Administrative Rules

(A) Correct typographical and calculation errors made in setting the PAL or reflect a

more accurate determination of emissions used to establish the PAL.

(B) Reduce the PAL if the owner or operator of the major stationary source creates

creditable emissions reductions for use as offsets under new source review for major

sources in nonattainment areas regulations.

(C) Revise the PAL to reflect an increase in the PAL as provided under subrule (11)

of this rule.

(ii) The department may reopen the PAL permit to accomplish any of the following:

(A) Reduce the PAL to reflect newly applicable federal requirements with compliance

dates after the PAL effective date.

(B) Reduce the PAL consistent with any other requirement that is enforceable as a

practical matter and that the state may impose on the major stationary source under the

state implementation plan.

(C) Reduce the PAL if the department determines that a reduction is necessary to

avoid causing or contributing to a national ambient air quality standard or PSD increment

violation, or to an adverse impact on an air quality related value that has been identified

for a federal class I area by a federal land manager and for which information is available

to the general public.

(iii) Except for a permit reopening for the correction of typographical and calculation

errors that do not increase the PAL level, all reopenings shall be carried out in accordance

with the public participation requirements of subrule (5) of this rule.

(9) Any PAL that is not renewed in accordance with subrule (10) of this rule shall expire

at the end of the PAL effective period, and the following requirements shall apply:

(a) Each emissions unit, or each group of emissions units, that existed under the PAL

shall comply with an allowable emission limitation under a revised permit established

according to both of the following:

(i) Within the time frame specified for PAL renewals in subrule (10)(b) of this rule, the

major stationary source shall submit a proposed allowable emission limitation for each

emissions unit, or each group of emissions units, if such a distribution is more appropriate

as determined by the department, by distributing the PAL allowable emissions for the

major stationary source among each of the emissions units that existed under the PAL. If

the PAL had not yet been adjusted for an applicable requirement that became effective

during the PAL effective period, as required under subrule (10)(e) of this rule, the

distribution shall be made as if the PAL had been adjusted.

(ii) The department shall determine whether and how the PAL allowable emissions

shall be distributed and issue a revised permit incorporating allowable limits for each

emissions unit, or each group of emissions units, as the department determines is

appropriate.

(b) Each emissions unit shall comply with the allowable emission limitation on a 12-

month rolling basis. The department may approve the use of monitoring systems, such as

source testing and emission factors, other than CEMS, CERMS, PEMS or CPMS to

demonstrate compliance with the allowable emission limitation.

(c) Until the department issues the revised permit incorporating allowable limits for each

emissions unit, or each group of emissions units, as required under subrule (9)(a)(ii) of this

rule, the major source shall continue to comply with a source-wide, multiunit emissions

cap equivalent to the level of the PAL emission limitation.

Page 31

Courtesy of Michigan Administrative Rules

(d) Any physical change or change in the method of operation at the major stationary

source shall be subject to major new source review requirements if such change meets the

definition of major modification in R 336.2801.

(e) The major stationary source owner or operator shall continue to comply with any

state or federal applicable requirements that may have applied either during the PAL

effective period or before the PAL effective period, except for those emission limitations

that had been established under R 336.2818(2), but were eliminated by the PAL under

subrule (2)(b)(iii) of this rule.

(10) All of the following apply to renewal of a PAL:

(a) The department shall comply with subrule (5) of this rule in approving any request

to renew a PAL for a major stationary source and shall provide both the proposed PAL

level and a written rationale for the proposed PAL level to the public for review and

comment. During public review, any person may propose a PAL level for the major source

for consideration by the department.

(b) A major stationary source owner or operator shall submit a timely application to the

department to request renewal of a PAL. A timely application is one that is submitted at

least 6 months before, but not earlier than 18 months from, the date of permit expiration.

This deadline for application submittal is to ensure that the permit will not expire before

the permit is renewed. If the owner or operator of a major stationary source submits a

complete application to renew the PAL within this time period, then the PAL shall continue

to be effective until the revised permit with the renewed PAL is issued.

(c) The application to renew a PAL permit shall contain all of the following information:

(i) The information required in subrule (3)(a) to (c) of this rule.

(ii) A proposed PAL level.

(iii) The sum of the potential to emit of all emissions units under the PAL, with

supporting documentation.

(iv) Any other information the owner or operator requests the department to consider

in determining the appropriate level for renewing the PAL.

(d) In determining whether and how to adjust the PAL, the department shall consider the

following:

(i) If the emissions level calculated in accordance with subrule (6) of this rule is equal

to or greater than 80% of the PAL level, the department may renew the PAL at the same

level without considering the factors in subrule (10)(d)(ii) of this rule.

(ii) The department may set the PAL at a level that it determines to be more

representative of the major source's baseline actual emissions, or that it determines to be

appropriate considering air quality needs, advances in control technology, anticipated

economic growth in the area, desire to reward or encourage the major source's voluntary

emissions reductions, or other factors as specifically identified by the department in its

written rationale.

(iii) Notwithstanding subrule (10)(d)(i) and (ii) of this rule, both of the following shall

apply:

(A) If the potential to emit of the major stationary source is less than the PAL, then

the department shall adjust the PAL to a level not greater than the potential to emit of the

major source.

(B) The department shall not approve a renewed PAL level higher than the current

PAL, unless the major stationary source has complied with subrule (11) of this rule.

Page 32

Courtesy of Michigan Administrative Rules

(e) If the compliance date for a state or federal requirement that applies to the PAL major

source occurs during the PAL effective period, and if the department has not already

adjusted for the requirement, then the PAL shall be adjusted at the time of PAL permit

renewal or renewable operating permit renewal, whichever occurs first.

(11) The following shall apply to increasing a PAL during the PAL effective period:

(a) The department may increase a PAL emission limitation only if the major stationary

source complies with the following provisions:

(i) The owner or operator of the major stationary source shall submit a complete

application to request an increase in the PAL limit for a PAL major modification. The

application shall identify the emissions units contributing to the increase in emissions so

as to cause the major stationary source's emissions to equal or exceed its PAL.

(ii) As part of this application, the major stationary source owner or operator shall

demonstrate that the sum of the baseline actual emissions of the small emissions units, plus

the sum of the baseline actual emissions of the significant and major emissions units

assuming application of BACT equivalent controls, plus the sum of the allowable

emissions of the new or modified emissions units, exceeds the PAL. The level of control

that would result from BACT equivalent controls on each significant or major emissions

unit shall be determined by conducting a new BACT analysis at the time the application is

submitted, unless the emissions unit is currently required to comply with a BACT or LAER

requirement that was established within the preceding 10 years. In such a case, the assumed

control level for that emissions unit shall be equal to the level of BACT or LAER with

which that emissions unit must currently comply.

(iii) The owner or operator obtains a major new source review permit for all emissions

units identified in subrule (11)(a)(i) of this rule, regardless of the magnitude of the

emissions increase resulting from them, that is, no significant levels apply. These

emissions units shall comply with any emissions requirements resulting from the major

new source review process, even though they have also become subject to the PAL or

continue to be subject to the PAL.

(iv) The PAL permit shall require that the increased PAL level shall be effective on the

day any emissions unit that is part of the PAL major modification becomes operational and

begins to emit the PAL pollutant.

(b) The department shall calculate the new PAL as the sum of the allowable emissions

for each modified or new emissions unit, plus the sum of the baseline actual emissions of

the significant and major emissions units, assuming application of BACT equivalent

controls as determined under subdivision (a)(ii) of this subrule, plus the sum of the baseline

actual emissions of the small emissions units.

(c) The PAL permit shall be revised to reflect the increased PAL level under the public

notice requirements of subrule (5) of this rule.

(12) The following are monitoring requirements for PALs:

(a) All of the following general provisions are required:

(i) Each PAL permit shall contain enforceable requirements for the monitoring system

that accurately determine plantwide emissions of the PAL pollutant in terms of mass per

unit of time. Any monitoring system authorized for use in the PAL permit shall be based

on sound science and meet generally acceptable scientific procedures for data quality and

manipulation. Additionally, the information generated by the system shall meet minimum

legal requirements for admissibility in a judicial proceeding to enforce the PAL permit.

(ii) The PAL monitoring system shall employ 1 or more of the 4 general monitoring

approaches in subdivision (b) of this subrule and shall be approved by the department.

(iii) Notwithstanding paragraph (ii) of this subdivision, the PAL may also employ an

alternative monitoring approach that meets paragraph (i) of this subdivision if approved by

the department.

(iv) Failure to use a monitoring system that meets the requirements of this rule renders

the PAL invalid.

(b) The following are acceptable general monitoring approaches when conducted in

accordance with subdivisions (c) to (i) of this subrule:

(i) Mass balance calculations for activities using coatings or solvents.

(ii) CEMS.

(iii) CPMS or PEMS.

(iv) Emission factors.

(c) An owner or operator using mass balance calculations to monitor PAL pollutant

emissions from activities using coating or solvents shall meet all of the following

requirements:

(i) Provide a demonstrated means of validating the published content of the PAL

pollutant that is contained in or created by all materials used in or at the emissions unit.

(ii) Assume that the emissions unit emits all of the PAL pollutant that is contained in

or created by any raw material or fuel used in or at the emissions unit, if it cannot otherwise

be accounted for in the process.

(iii) Where the vendor of a material or fuel, which is used in or at the emissions unit,

publishes a range of pollutant content from such material, then the owner or operator shall

use the highest value of the range to calculate the PAL pollutant emissions unless the

department determines there is site-specific data or a site-specific monitoring program to

support another content within the range.

(d) An owner or operator using CEMS to monitor PAL pollutant emissions shall meet

both of the following requirements:

(i) CEMS shall comply with applicable performance specifications found in 40 C.F.R.

part 60, appendix B, adopted by reference in R 336.1902.

(ii) CEMS shall sample, analyze, and record data at least every 15 minutes while the

emissions unit is operating.

(e) An owner or operator using CPMS or PEMS to monitor PAL pollutant emissions

shall meet both of the following requirements:

(i) The CPMS or the PEMS shall be based on current site-specific data demonstrating

a correlation between the monitored parameters and the PAL pollutant emissions across

the range of operation of the emissions unit.

(ii) Each CPMS or PEMS shall sample, analyze, and record data at least every 15

minutes, or at another less frequent interval approved by the department, while the

emissions unit is operating.

(f) An owner or operator using emission factors to monitor PAL pollutant emissions

shall meet all of the following requirements:

(i) All emission factors shall be adjusted, if appropriate, to account for the degree of

uncertainty or limitations in the factors' development.

(ii) The emissions unit shall operate within the designated range of use for the emission

factor, if applicable.

(iii) If technically practicable, the owner or operator of a significant emissions unit that

relies on an emission factor to calculate PAL pollutant emissions shall conduct validation

testing to determine a site-specific emission factor within 6 months of PAL permit

issuance, unless the department determines that testing is not required.

(g) A major source owner or operator shall record and report maximum potential

emissions without considering enforceable emission limitations or operational restrictions

for an emissions unit during any period of time that there is no monitoring data, unless

another method for determining emissions during such periods is specified in the PAL

permit.

(h) Notwithstanding the requirements in subdivisions (c) to (g) of this subrule, if an

owner or operator of an emissions unit cannot demonstrate a correlation between the

monitored parameters and the PAL pollutant emissions rate at all operating points of the

emissions unit, then the department shall do either of the following at the time of permit

issuance:

(i) Establish default values for determining compliance with the PAL based on the

highest potential emissions reasonably estimated at each unmonitored operating point.

(ii) Determine that operation of the emissions unit during operating conditions when

there is no correlation between monitored parameters and the PAL pollutant emissions is a

violation of the PAL.

(i) All data used to establish the PAL pollutant shall be revalidated through performance

testing or other scientifically valid means approved by the department. Testing shall occur

at least once every 5 years after issuance of the PAL.

(13) The PAL permit shall require the following recordkeeping requirements:

(a) Require an owner or operator to retain a copy of all records necessary to determine

compliance with this rule and the PAL, including a determination of each emissions unit's

12-month rolling total emissions, for 5 years from the date of such record.

(b) Require an owner or operator to retain a copy of all of the following records, for the

duration of the PAL effective period plus 5 years:

(i) A copy of the PAL permit application and any applications for revisions to the PAL.

(ii) Each annual certification of compliance under the renewable operating permit and

the data relied on in certifying compliance.

(14) The owner or operator shall submit semiannual monitoring reports and prompt

deviation reports to the department in accordance with the applicable renewable operating

permit program. The reports shall meet the following requirements:

(a) The semiannual report shall be submitted to the department concurrently with the

semiannual report required by the renewable operating permit for the stationary source.

The report shall contain all of the following information:

(i) The identification of owner and operator and the permit number.

(ii) Total annual emissions in tons per year based on a 12-month rolling total for each

month in the reporting period recorded under subrule (13)(a) of this rule.

(iii) All data relied upon, including, but not limited to, any quality assurance or quality

control data, in calculating the monthly and annual PAL pollutant emissions.

renewable operating permit program, certifying the truth, accuracy, and completeness of

the information provided in the report.

(b) The major stationary source owner or operator shall promptly submit reports of any

deviations or exceedance of the PAL requirements, including periods where monitoring is

not available. A report submitted under R 336.1213(3)(c) shall satisfy the reporting

requirement. The deviation reports shall be submitted within the time limits prescribed by

the major source's renewable operating permit. The reports shall contain all of the

following information:

(i) The identification of owner and operator and the permit number.

test or method within 3 months after completion of the test or method.

(15) The owner or operator of a facility complying with an actuals PAL may install a new

emissions unit without first obtaining a permit to install under R 336.1201, if the following

requirements are met:

(a) The new emissions unit will not cause a meaningful change in the nature or quantity

of toxic air contaminants emitted from the major stationary source, unless the new

emissions unit is otherwise exempt under R 336.1278 to R 336.1290. In determining

whether the new emissions unit will cause a meaningful change in the nature or quantity

of toxic air contaminants, the following shall apply:

(i) The owner or operator shall demonstrate to the department that a meaningful change

in the nature or quantity of toxic air contaminants has not occurred. The owner or operator

may devise its own method to perform this demonstration subject to approval by the

department. However, if the applicant demonstrates that all toxic air contaminant

emissions from a new emissions unit are within the levels specified in R 336.1226 or R

336.1227, then a meaningful change in toxic air contaminants has not occurred.

(ii) If, using the methods described in paragraph (i) of this subdivision, the owner or

operator determines that the installation of new emission units will cause a meaningful

change in the nature or quantity of toxic air contaminant emissions, then the owner or

operator shall obtain a state-only enforceable permit to install under R 336.1201(1)(b).

kept on site for the life of the new emissions unit and made available to the department

upon request.

(b) The new emissions unit will not emit a regulated new source review pollutant that is

not subject to a PAL, unless the new emissions unit is eligible for an exemption listed in R

336.1201 to R 336.1290.

(c) The new emissions unit will not be a newly constructed or reconstructed major source

of hazardous air pollutants.

(d) The installation of the new emissions unit will not cause the violation of any other

applicable requirement.

(e) The owner or operator shall notify the department of the installation of a new

emissions unit using the procedure specified in R 336.1215(3)(c).
