1. Scope and Applicability 

A. Geographic scope. This regulation shall be effective in all ambient air quality control regions in 

the State. 

B. General Requirement . A Part 70 license is required for all major sources . Once a source 

requires an air emission license, all emissions units which emit regulated pollutants at the source 

must be included except those insignificant activities listed in Appendix B of this Chapter. At 

such time that a particular source or modification becomes a major 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 source or modification otherwise to emit a pollutant, such as a 

restriction on hours of operation, then the requirements of Chapter 115(4)(A) Major 

Modification or Major Source shall apply to the source or modification as though construction 

had not yet commenced on the source or modification . 

C. Part 70 license is required for the following : 

(1) Any Part 70 major source; 

Chapter 140: Part 70 Air Emission License Regulations

(1) All sources listed in Subsection 1(C) of this Chapter that are not Part 70 major sources, Title 

IV sources, or solid waste incineration units required to obtain a license pursuant to Section 

129(e) of the CAA are exempted by the Department from the obligation to obtain a Part 70 

license until such time as EPA completes a rulemaking to determine how the program should 

be structured for nonmajor sources ; 

(2) In the case of nonmajor sources subject to a standard or other requirement under either 

Section 111 (Standards of Performance for New Stationary Sources) or Section 112 

(Hazardous Air Pollutants) of the CAA promulgated after July 21, 1992, EPA will determine 

whether to exempt any or all such sources from the requirement to obtain a Part 70 license at 

the time that the new standard is promulgated; 

(3) Unless otherwise required by the Department to obtain a Part 70 license, the following 

sources are exempted from the obligation to obtain a Part 70 license : 

(a) All sources that would be required to obtain a Part 70 license solely because they are 

subject to Part 60, Subpart AAA - Standards of Performance for New Residential Wood 

Heaters; 

(b) All sources that would be required to obtain a Part 70 license solely, because they are 

subject to Part 61, Subpart M - National Emission Standard for Hazardous Air Pollutants 

for Asbestos, Section 61.145, Standard for Demolition and Renovation; and 

(c) Any source that is licensed under Chapter 115 that would otherwise be subject to this 

Chapter, but received federally enforceable license conditions to retain a minor source 

status as allowed by 40 CFR Part 70. 

(4) Any source listed in this subsection that is exempted from the requirement to obtain a Part 70 

license may opt to apply for a Part 70 license under this Chapter. 

NOTE: A source exempt from Chapter 140 may be subject to the requirements of obtaining an 

air emission license under Chapter 115 of the Department Regulations .

limits, design, equipment, work practices or operational standards for activities emitting 

hazardous air pollutants if no ambient air quality standards have been established for those 

pollutants. 

Y. Modifications of Part 70 HAP sources 

Sources applying for a new Part 70 HAP source, a modification or reconstruction of a Part 70 

HAP source which is not currently subject to a HAP emission limitation will be reviewed only 

under the New Source Review section of Chapter 115. 

Z. Computation of time period 

"Days" are calendar days unless otherwise designated. "Working days" excludes Saturdays, 

Sundays, state holidays and state shutdown days. In computing any period of time prescribed or 

allowed by Chapter 140, the last day of the period is to be included unless it is a Saturday, 

Sunday, state holiday, or state shutdown day in which event the period runs until the end of the 

next day which is not a Saturday, Sunday, state holiday, or state shutdown day. If a person is 

required to take some action within a prescribed period after service of notice or other paper and 

the notice or paper is served by mail, three (3) days shall be added to the prescribed period. 

AA. Emergency provision

license issuance; 

(3) A Best Practical Treatment (BPT) analysis as described below: 

(a) Best Practical Treatment (BPT). Emissions from existing sources undergoing renewal of 

a Part 70 license or the issuance of the initial Part 70 license shall be deemed to be 

receiving best practical treatment if those emissions are being controlled by pollution 

control apparatus which was installed less than 15 years prior to the date of license 

application approval, or an acceptable best practical treatment analysis shows that those 

emissions are being controlled in a manner consistent with emission controls commonly 

used in sources of similar age and design in similar industries. 

For emissions from existing sources controlled by pollution control apparatus which was 

installed less than 15 years prior to the date of license application approval, the applicant 

shall submit a summary of the pollution control apparatus for those emission sources . 

If the pollution control apparatus has been installed 15 years or more from the date of 

license application approval, the applicant must demonstrate that each emissions unit is 

receiving BPT and such demonstration shall consider the emission limit for which the air 

pollution control system was designed, the emission limitations adopted by the 

Department and in effect at the time of submission of an application for renewal, as well 

as the reliability, age, and life expectancy of the air pollution control system. 

BPT shall not require the use of a lower sulfur content unless a lower sulfur fuel is 

required to comply with the applicable emissions standards or applicable ambient air 

quality standards. 

BPT shall not force replacement of existing air pollution control equipment on the basis 

that more efficient or reliable air pollution control equipment is available at the time of 

renewal. However, BPT may require replacement with more efficient or reliable air 

pollution control equipment under the following conditions: 

(i) The applicant is proposing replacement of the existing air pollution control 

equipment; 

(ii) Any emissions unit violates the applicable emission limitation; 

(iii) Additional reductions are necessary to achieve or maintain ambient air quality 

standards; 

(iv) The Department determines that previously uncontrolled emissions should be 

controlled in order to prevent an unreasonable risk to the environment or public 

health;

controlled to a greater efficiency considering the toxicity of air contaminants; or 

(vi) Additional reductions are necessary to restore ambient increment even if that 

ambient increment was previously authorized to the owner or operator of an existing 

source. 

BPT may require the use of additional instrumentation, operating practices, automated 

process controls, upgrading of component parts, emissions testing, requirements for 

continuous emission monitors, maintenance programs for air pollution control 

equipment, or record keeping to demonstrate performance of air pollution control 

systems or other mitigating measures. 

(4) BPT for lapsed licenses shall undergo an analysis similar to Section 4(A)(4)(d) of Chapter 

115 (BACT). 

Reasonably Available Control Technology (RACT). The applicant for an existing source 

located in, or whose emissions of a federal nonattainment pollutant result in a significant 

impact to any federal nonattainment area, shall include a summary of the conditions the 

source complies with to meet RACT requirements. 

(6) Best Available Retrofit Technology (BART). An existing source with emissions that the 

Department has determined to cause an adverse impact on visibility in any Class I area or any 

integral vista for that Class I area, shall demonstrate that each emissions unit contributing to 

the adverse impact on visibility will receive BART as expeditiously as practicable, but no 

later than five (5) years after the Department identifies BART. 

Hazardous Air Pollutants (HAPs). If an existing source is subject to a newly applicable HAP 

emission limitation, the application shall be submitted according to the schedule in Appendix 

C and Section 6(B) and shall contain the HAP information as required by Section 6 of this 

Chapter. 

(8) Ambient Air Quality Impact Analysis . If required by the Department pursuant to this 

Chapter, the applicant shall submit the results of any ambient air quality impact analyses, 

including an analysis of the impacts to Air Quality Related Values and impact on visibility if 

the Department determines that the source may affect ambient increments or Air Quality 

Related Values in any Class I area or integral vista to that Class I area. The analysis shall be 

performed pursuant to this Chapter. This analysis shall not be used in the completeness 

determination of the application.

that the facility can prove to the satisfaction of the Department that there were 

intervening days during which no violation occurred or that the violation was not 

continuing in nature; and 

(c) the licensee may, upon the approval of the Department following the successful 

demonstration of compliance at alternative load conditions, operate under such 

alternative load conditions on an interim basis prior to a demonstration of 

compliance under normal and representative process and operating conditions.

Such deviations shall include, but are not limited to malfunctions, failures, 

downtime, and any other similar change in operation of air pollution control systems 

or the emission unit itself that is not consistent with the terms and conditions of the 

air emission license . 

(a) The licensee shall notify the Commissioner within 48 hours of a violation of 

any emission standard and/or a malfunction or breakdown in any component 

part that causes a violation of any emission standard, and shall report the 

probable cause, corrective action, and any excess emissions in the units of 

the applicable emission limitation; 

(b) The licensee shall submit a report to the Department on a quarterly basis if a 

malfunction or breakdown in any component part causes a violation of any 

emission standard, together with any exemption requests. 

Pursuant to 38 MRSA § 349(9), the Commissioner may exempt from civil 

penalty an air emission in excess of license limitations if the emission occurs 

during start-up or shutdown or results exclusively from an unavoidable 

malfunction entirely beyond the control of the licensee and the licensee has 

taken all reasonable steps to minimize or prevent any emission and takes 

corrective action as soon as possible. There may be no exemption if the 

malfunction is caused, entirely or in part, by poor maintenance, careless 

operation, poor design or any other reasonably preventable condition or 

preventable equipment breakdown . The burden of proof is on the licensee 

seeking the exemption under this subsection.

General license to owners or operators of Part 70 sources that qualify, and may grant the Part 

70 General license without repeating the public participation and affected state review 

procedures on the Part 70 draft license. Such a grant shall not be a final action by the 

Department for purposes of judicial review . 

14. Ambient Air Quality Analysis 

A. General. It shall be the burden of any applicant to provide an affirmative demonstration that its 

emissions, in conjunction with all other sources, will not violate ambient air quality standards, 

established pursuant to Chapter 110 of Department Regulations, except that Part 70 sources in 

nonattainment areas or which significantly impact a nonattainment area shall be required to 

demonstrate that the Part 70 source's emissions are consistent with Reasonable Further Progress 

provisions of the State Implementation Plan. An applicant may use ambient air monitoring, 

modeling, or other assessment techniques as approved by the Department and shall be consistent 

with EPA regulations and guidelines or other requirements under the CAA. The analyses shall 

include relevant emissions units at the Part 70 source, meteorological and topographical data 

necessary to estimate such impacts, and shall consider the impact of fugitive emissions, to the 

extent quantifiable, secondary emissions, and emissions from other existing sources including 

increases in mobile and area source emissions impacting the same area. 

The level of analysis shall depend upon the size of the Part 70 source, the regulated air pollutants 

emitted, existing air quality, proximity to Class I or nonattainment areas, or areas where 

increment has been substantially consumed. (For the purposes of this Subsection, the Class I 

area shall include any conservation easements under the jurisdiction of an appropriate Federal 

Land Manager as of August 7, 1977.) The air quality impact analysis, in general, will not be 

Chapter 140: Part 70 Air Emission License Regulations 

-46- 
06-096 DEPARTMENT OF ENVIRONMENTAL PROTECTION 

required of the applicant for those regulated pollutants that are not listed under "significant 

emissions increase" in Chapter 100 of the Department's Regulations . The analysis shall be 

conducted in accordance with the provisions of Subsection 14(C) of this Chapter, Chapter 116 of 

the Department's Regulations and Appendix W to 40 CFR Part 51 - Guideline on Air Quality 

Models. 

Air quality modeling conducted as part of the licensing of a new Part 70 source or modification 

to a Part 70 source in the United States is substantially governed by the Appendix W to 40 CFR 

Part 51 - Guideline on Air Quality Models. That modeling guidance was first promulgated in 

1978 and by law, must be routinely updated by EPA. Thus, federal regulatory guidance on 

modeling and the list of acceptable models do change. The Department recognizes that air 

dispersion modeling guidance will be periodically updated, to reflect the latest federal guidance. 

To maintain an orderly licensing process in the State, applicants will be required to conform with 

those procedures and guidelines in effect at the time of Department approval of a written 

modeling protocol that meets all applicable requirements provided the applicant completes 

modeling, as approved, and submits its results within six (6) months of the date of approval of 

the protocol. If the protocol calls for collection of on-site meteorological data, then the starting 

date for the on-site data collection must be no later than 6 months after approval of the protocol 

and modeling results must be submitted within six (6) months of obtaining acceptable on-site 

meteorological monitoring data. Requests by the applicant to modify the modeling protocol will 

require conformance with current applicable air dispersion modeling guidance. 

(1) Ambient Air Quality Monitoring Requirements. Monitoring done by the owner or operator 

shall conform to the requirements of 40 CFR Part 58, Appendix B and the Department's 

Quality Assurance Plan (or other plan approved by the Department) during the operation of 

monitoring stations . It is recommended that a written protocol be developed by the owner or 

operator and the Department when a Part 70 source is required to conduct either preconstruction or post-construction monitoring. The protocol shall, at a minimum, specify the 

monitoring sites, frequency of sampling, data recovery, pollutants, and monitoring 

method(s) . 

(2) Air Quality Impact Modeling Requirements. 

(a) All estimates of ambient concentrations required by an ambient or increment impact 

analysis shall be based on the relevant air quality models, data bases, and other 

requirements specified in the current Appendix W to 40 CFR Part 51 - Guideline on Air 

Quality Models, and in accordance with Subsection 14(C) of this Chapter, and Chapter 

116 of the Department's regulations . These guidelines require evaluation of the effect of 

terrain on ambient concentrations . Fugitive emissions, to the extent quantifiable, shall be 

considered. 

(b) All input and output files used in the final Class I and Class II MAAQS and increment 

compliance modeling analyses and Class I AQRV and visibility modeling analyses shall 

be submitted to the Department on 3V2" diskettes, compact discs or other media 

formatted for use by computer software which the Department uses unless otherwise 

approved by the Commissioner. 

(c) Where an air quality impact model specified in the Appendix W to 40 CFR Part 51 -

Guideline on Air Quality Models, is inappropriate, the model may be changed or another 

Chapter 140: Part 70 Air Emission License Regulations 

-47- 
06-096 DEPARTMENT OF ENVIRONMENTAL PROTECTION 

model substituted; such change or substitution shall be subject to public comment and 

the written approval of the Department and the Regional Administrator of the U. S . 

Environmental Protection Agency or his designee. Methods like those outlined in the 

Protocol for Determining the Best Performing Model (EPA-454/R-92-025) and the 

Interim Procedures for Evaluating Air Quality Models: Experience with Implementation 

(EPA-450/4-85-006) should be used to determine the comparability of air quality models. 

B. Renewal of a Part 70 license 

(1) A previously submitted impact analysis shall be acceptable unless: 

(a) It has been found to be deficient with respect to requirements set forth in Subsection 

14(A) of this Chapter; 

(b) The impact analysis fails to reflect available information with respect to ambient air 

quality levels in the area, which, based upon the Department's expertise, may reasonably 

be expected to be significantly impacted by the Part 70 source; 

(c) The Part 70 source emits a regulated pollutant for which an ambient air quality standard 

has been adopted and whose impact was not addressed in the original impact analysis; 

(d) There are changes in stack or building configurations or other factors which are 

determined to significantly alter the dispersion characteristics of the Part 70 source. 

(2) Continuation of an ambient air monitoring or meteorological monitoring program shall be 

made on a case-by-case basis at the time of the renewal. It shall be the burden of the 

applicant to demonstrate the adequacy of existing data, its relationship to past, present, and 

future facility operating conditions, and the adequacy of other means to document continuing 

compliance. 

(3) An existing Part 70 source shall be exempt from an impact analysis with respect to a 

regulated pollutant whose allowable emissions, after the application of control technology 

requirements specified in Section 4 of this Chapter, do not exceed the following, unless the 

Part 70 source is located in or near a Class I area or an area where the available air quality is 

limited, or other extenuating circumstances exist: 

(a) 50 tons per year (tpy) for SOZ; 

(b) 250 tpy for CO; 

(c) 25 tpy for PM1o or TSP; 

(d) 100 tpy for NO,, (measured as NOZ); 

(e) 0.6 tpy for Lead (Pb); or 

(f) 0.2 tpy of total Chromium. 

Chapter 140: Part 70 Air Emission License Regulations 

-48- 
06-096 DEPARTMENT OF ENVIRONMENTAL PROTECTION 

C. Modeling/data collection protocol. Any air quality dispersion modeling or data collection 

program shall be developed consistent with the following requirements : 

(1) Guidance. All air quality dispersion modeling and meteorological data collection shall be 

conducted consistent with Subsection 14 of this Chapter and Appendix W to 40 CFR Part 51 

- Guideline on Air Quality Models. 

NOTE: The applicant should consult with the Department and Federal Land Managers 

(potentially affected federal lands are listed in Chapter 114 of the Department's 

Regulations) if Class I analyses are required, prior to submitting a modeling/data 

collection protocol. The applicant is responsible for obtaining the training necessary 

to perform the required air dispersion modeling and meteorological data collection. 

(2) Variance from guidance. Upon an applicant's written request, the Department may grant a 

variance from any of the requirements set forth in Subsection 14 of this Chapter and 

Appendix W to 40 CFR Part 51 - Guideline on Air Quality Models, when the Department 

finds that the alternative proposed by the applicant will not significantly affect the accuracy 

of the modeling, and/or when data collection results or compliance with the requirements 

specified in Subsection 14 of this Chapter and Appendix W to 40 CFR Part 51 - Guideline 

on Air Quality Models is technically infeasible or economically unreasonable for the 

applicant . For any Part 70 source subject to PSD review, the variance shall be subject to 

EPA review, written approval, and shall be subject to notice and opportunity for public 

comment pursuant to 40 CFR Parts 51 .160 (f) (2) and 51 .166 (1) (2). 

(3) Significant impact modeling protocol for SO2, NO2, CO and PMIO. Prior to undertaking 

significant impact modeling for SO2, NOZ, CO and PMIO, the applicant shall provide in 

writing to the Department, a description of the following factors that the applicant proposes 

to use in the significant impact modeling demonstration (see Appendix W to 40 CFR Part 51 

- Guideline on Air Quality Models for more specific guidance) : 

(a) Operating scenarios and emission units in English and metric units; 

(b) Regulated air pollutants; 

(c) Model(s) and methodologies ; 

(d) Origin of meteorological data; 

(e) Period of meteorological record; 

Receptor grid (listing of coordinates and elevations, topographic maps covering the 

receptor grid area, map of receptors and, if applicable, a listing of all Digital Elevation 

Model (DEM) quadrangles used and method(s) used to convert DEM data to the 

proposed receptor grid). If DEM data is being used to create a rectangular receptor grid, 

then the elevation of each receptor point shall be the highest elevation within the grid 

cell . The grid cell is defined as an area enclosed by boundaries located half way to the 

nearest receptor in each direction; 

(g) Any special (e.g ., fenceline, air intake or flagpole) receptors ;

NOTE: An original plot plan is preferred, but if a photocopy is submitted, care should be 

taken to make sure that the scale is not changed on any area of the plot. 

Building dimension and Good Engineering Practice (GEP) analysis techniques. For each 

stack, all buildings that are large enough and close enough to influence the stack should 

be considered in the GEP analysis. 

As expeditiously as possible and within thirty (30) calendar days of receipt of this 

information, the Department shall notify the applicant in writing that such information is 

complete and acceptable for modeling or notify the applicant in writing of the reason(s) 

why the information is not complete. If the information is not complete, the Department 

shall clearly identify the changes or additional information that must be submitted to 

complete the protocol requirements . 

(4) Submittal of significant impact modeling. 

(a) Prior to undertaking the final air quality dispersion modeling demonstration, 

applicant shall submit the following for review : 

the 

(i) Significant impact modeling results (If all modeled impacts of any regulated 

pollutant are below the significant impact levels for all averaging periods, then no 

further analysis is necessary for that pollutant); 

(ii) Emissions data for regulated pollutants not in the significant impact modeling 

protocol; 

(iii) A preliminary analysis of nearby sources that will not be included in the background 

concentration analysis ; 

NOTE: The Department is responsible for the final decision of off-site sources to be 

modeled. The Department will provide the applicant with a list of any additional 

sources that may have to be included in the final modeling analysis and the requisite 

model input data for these sources . This list will contain all data required for model 

input including source location(s), emission rates, stack parameters, and necessary 

building dimensions for the applicant to determine direction-specific building 

parameters. 

(iv) Background concentration data. Conservative background values are available from 

the Department for all areas of the state . Should the applicant choose not to use the 

conservative background values supplied by the Department, the applicant shall be 

responsible for determining background values based on data normally supplied by 

Chapter 140: Part 70 Air Emission License Regulations 

-50- 
06-096 DEPARTMENT OF ENVIRONMENTAL PROTECTION 

and in consultation with the Department. For sources needing more refined 

background values, general guidance on determining background determinations 

based on monitoring data is provided in the most recent version of the Departments 

Guideline Document For Background Air Quality Determinations . Particular care 

must be taken when determining background values so that they do not implicitly 

include any impacts of the source(s) being modeled in order to avoid double 

counting; and 

Processed meteorological data base (if required by the Department). The use of five 

(5) consecutive years of off-site National Weather Service NWS) meteorological 

data (or other data equivalent or better in accuracy and detail to the NWS data) or at 

least 1 year of site specific data is the minimum requirement for modeling 

applications . If more than one (1) year (and up to five (5) years) of acceptable data 

is available, it shall be used in the air quality analysis . If there is a gap in data from a 

catastrophic incident or a persistent but subtle problem that evades detection, a two 

(2), three (3), four (4) or five (5) year on-site meteorological database acceptable for 

modeling purposes need not be compiled from two (2), three (3), four (4) or five (5) 

consecutive years or twenty-four (24), thirty-six (36), forty-eight (48) or sixty (60) 

consecutive months of data. If this is the case, then the applicant shall write to the 

Department requesting an exemption from the consecutive two (2), three (3), four (4) 

or five (5) year database requirement . If data requirements, source configurations or 

characteristics of the surrounding area change, the database may need to be updated 

after consultation with the Department. However, a requirement to collect a new 

database will neither preclude the applicant's ability to use the existing database in 

the interim data collection period nor require the applicant to redo any previously 

submitted analyses that used the original database. 

(b) Within thirty (30) calendar days of receipt of this information, the Department shall 

notify the applicant of the following in writing : 

(i) The submitted information is complete and acceptable for modeling or the reason(s) 

why the information is not complete. If the information is not complete, the 

Department shall clearly identify the changes or additional information that must be 

submitted to complete the protocol requirements; and 

(ii) For each regulated pollutant for which there are significant impacts, the Department 

shall specify which operating scenarios and other nearby sources, if any, needs to be 

further modeled. 

If the applicant requests in writing, information in the possession of the Department that 

is required for modeling (for example, emissions which are included in baseline 

emissions, background data or other emissions data from nearby sources), the 

Department shall attempt to provide such information to the applicant within thirty (30) 

calendar days . 

(5) Air quality dispersion modeling protocol . If impacts from SO2, NO2, CO and PMIO are above 

significance or if there are other regulated pollutants to be modeled, then the applicant must 

provide in writing to the Department, a description of the following factors (if different from 

previously submitted data) that the applicant proposes to use in the air quality dispersion

Model (DEM) quadrangles used and method(s) used to convert DEM data to the 

proposed receptor grid). If DEM data is being used to create a rectangular receptor grid, 

then the elevation of each receptor point shall be the highest elevation within the grid 

cell. The grid cell is defined as an area enclosed by boundaries located half way to the 

nearest receptor in each direction ; 

(g) Any special (e.g ., fenceline, air intake or flagpole) receptors ; 

(h) Identity of emissions which are included in baseline emissions;

NOTE: An original plot plan is preferred, but if a photocopy is submitted, care should be 

taken to make sure that the scale is not changed on any area of the plot. 

(j) Building dimension and Good Engineering Practice (GEP) analysis techniques . For each 

stack; all buildings that are large enough and close enough to influence the stack should 

be considered in the GEP analysis . Subpiit all BPIP input and output files on compact 

disc, 31/2" diskette or other media approved by the Department. All tiers of a building 

will be input as tiers and not as separate buildings and 

(k) Background concentration data.

Department over the first three years and that this represents at least eighty percent of the total 

emissions from facilities subject to this Chapter and categorized by the submittal schedule in this 

Appendix. 

The Department shall act on all Part 70 license applications over a five year period commencing on 

the date of EPA's approval of Maine's operating permit program.

part 70 HAP source must submit the information required under this Chapter relating to the HAP 

standard within six months following EPA's promulgation of the HAP emission limitation. 

If EPA promulgates a HAP emission limitation applicable to an existing Part 70 HAP source less 

than twelve months prior to the scheduled submittal date for a Phase II application, as established 

in this section, the applicant must submit the information required under this Chapter relating to 

the HAP standard within six months following EPA's promulgation of the HAP emission 

limitation, or by the application date established in this section, whichever is later . An 

application shall be considered complete as of the phase II application date provided all other 

information required by this Chapter is submitted by the scheduled Phase II application date.
