Request for Coverage under the General Air Quality Permit for New or 

Modified Minor Source Gasoline Dispensing Facilities in Indian Country

within California

Last Modified: September 29, 2016

Version 1.0

This Request for Coverage under the General Air Quality Permit for New or Modified Minor Source Gasoline Dispensing 

Facilitiesin Indian Country within California (the General Permit) is available forthe construction or modification of certain 

minor source gasoline dispensing facilities in Indian country, within the geographical boundaries of California. Specifically, 

the General Permit is potentially available for such facilities within the geographic boundaries of California that are located 

in an Indian reservation or in another area of Indian country (as defined in 18 U.S.C. 1151) over which an Indian tribe, or 

the EPA, has demonstrated that the tribe has jurisdiction, and where there is no EPA-approved program in place. A 

gasoline dispensing facility (GDF) is any stationary source which dispenses gasoline into the fuel tank of a motor 

vehicle, motor vehicle engine, nonroad vehicle, or nonroad engine, including a nonroad vehicle or nonroad engine 

used solely for competition e.g., a retail gas station).

An owner or operator of a source that meets the eligibility criteria may seek coverage under the General Permit by 

submitting this Request for Coverage when the General Permit becomes effective. You may contact your reviewing 

authority or check the following website to determine whether the General Permit is effective: https://www.epa.gov/caapermitting/california-tribal-gasoline-permits.

Questionnaire: For assistance with determining whether the proposed new or modified GDF source may be eligible for 

the General Permit and the owner or operator should submit this Request for Coverage, the owner or operator may 

refer to the “Questionnaire under the General Air Quality Permit for New or Modified Minor Source Gasoline Dispensing 

Facilities in Indian Country within California” (Questionnaire).

Instructions: For assistance with completing the Request for Coverage, the owner or operator should refer to the 

“Instructions for Request for Coverage under the General Air Quality Permit for New or Modified Minor Source 

Gasoline Dispensing Facilities in Indian Country within California” (Instructions), which provide additional detail on the 

requested information. Information on the definition of a “modification” and “potential to emit” or “PTE” can be found 

at CFR 49.152(d) and in the Instructions

Eligibility Criteria

The owner or operator must meet the following criteria to potentially qualify for coverage under the General Permit and 

to submit a Request for Coverage:

• You, the owner/operator, plan to construct a new or modified minor source, as defined in 40 CFR 49.152(d), that 

is, or includes, a GDF, and your source has a potential to emit (PTE) less than the Prevention of Significant 

Deterioration and New Source Review (NSR) major source thresholds. For purposes of this eligibility criterion, your 

PTE calculation must include the PTE of all existing, new and modified emission units at your source, including 

those that are not part of the GDF.

• Your new or modified minor source gasoline dispensing facility is located within the geographic boundaries of 

California, and located in an Indian reservation or in another area of Indian country (as defined in 18 U.S.C. 1151) 

over which an Indian tribe, or the EPA, has demonstrated that the tribe has jurisdiction, and where there is no 

EPA-approved program in place.

• The new or modified GDF is not, or will not, be located at a major source of hazardous air pollutants.

• If the source is located in an area that has been designated as serious, severe or extreme nonattainment for the 

federal ozone standard, after the proposed construction or modification project, the source (including existing 

equipment as well as new and modified equipment) will dispense less than 15,000,000 gallons of fuel per year 

based on a 12-month rolling total. If the source is located in an area that is attainment, unclassifiable or 

attainment/unclassifiable or marginal/moderate nonattainment for the federal ozone standard, after the 

proposed construction or modification project, the source (including existing equipment as well as new and

modified equipment) will dispense less than 25,000,000 gallons of fuel per year based on a 12-month rolling total.

• The proposed new or modified GDF will use a Stage I dual-point vapor balance system.

• If the proposed new or modified GDF is, or will be, located in a federal ozone nonattainment area, it will be

equipped with a CARB Phase II Enhanced Vapor Recovery (EVR) System and In-Station Diagnostic (ISD) system, 

using CARB certified equipment.

• Any new or modified emergency engines at the source are exempt under 40 CFR 49.153(c).

• The owner or operator demonstrates that the source meets one of the criteria listed in Appendix A with respect 

to the protection of any and all species that are federally-listed as threatened or endangered under the 

Endangered Species Act (ESA) or of habitat that is federally-designated as critical habitat under the ESA; and

• The owner or operator has completed the screening process in Appendix B to determine if the construction, 

modification or operation of your new or modified minor source of air pollutants has the potential to cause effects 

to historic properties.

• You can otherwise comply with the terms and conditions of the General Permit.

In addition, the General Permit is not available to:

• Sources that store or transfer aviation gasoline at airports or other similar sources that dispense fuel through 

mobile (portable) fueling equipment.

• A proposed or modified GDF located in an ozone nonattainment area that includes any aboveground storage tanks

(ASTs) as part of the new or modified source.

Reviewing Authority Discretion to Terminate General Permit Coverage

Applicants should note that the reviewing authority retains discretion to terminate a source’s coverage under this General 

Permit and require a source-specific permit even if the above criteria are met. Reasons the reviewing authority may 

terminate a permitted source’s coverage under this General Permit include:

If part of a Tribe’s area of Indian country is designated as attainment and another 

part as nonattainment, the applicable threshold for a proposed source or 

modification is determined based on the designation where the source would be 

located. If the source straddles the two areas, the more stringent thresholds apply.

b

In extreme ozone nonattainment areas, section 182(e)(2) of the Act requires any 

change at a major source that results in any increase in emissions to be subject to 

major NSR permitting. In other words, any changes to existing major sources in 

extreme ozone nonattainment areas are subject to a “0” tpy threshold, but that 

threshold does not apply to minor sources.

Appendix A – Threatened or Endangered Species Requirements

The purpose of this appendix is to assist you in completing the screening procedure for addressing threatened or 

endangered species when submitting your Request for Coverage under the General Air Quality Permit for New or 

Modified Minor Source Gasoline Dispensing Facilities in Indian Country within California (General Permit). In order to

be eligible for coverage under the General Permit, you must demonstrate that you qualify under one of the criteria

listed in this appendix with respect to the protection of species that are federally-listed as threatened or endangered

under the ESA or of habitat that is federally-designated as “critical habitat” under the ESA. The EPA must provide 

confirmation that you satisfactorily completed this screening procedure in order for you to be eligible for coverage 

under the General Permit.

This appendix provides you information on the following:

• Section 1.0: Listed Species Eligibility Criteria and

• Section 2.0: Guidance for Determining Which Listed Species Criterion Applies.

1.0 Listed Species Eligibility Criteria

To be eligible for coverage under the General Permit, you must satisfactorily complete the screening procedure and 

meet one of the eligibility criteria listed below. You must also specify in your submittal the basis for your selection of

the applicable eligibility criterion and provide documentation supporting the criterion selected. 

Note: (1) Your determination must provide sufficient documentation to support your determination that you satisfy the

requirements of the particular criterion you have selected. (2) While coordination between you and the U.S. Fish and

Wildlife Service (FWS) and/or the National Marine Fisheries Service (NMFS; together,the “Services”) is not necessarily

required in all cases, the EPA encourages you to coordinate with the relevant Service(s) and to do so early in the

planning process prior to submitting your Request for Coverage.

You must comply with any applicable terms, conditions, or other requirements developed in the process of meeting 

any of the eligibility criteria (A-E) in this section to remain eligible for coverage under the General Permit. 

Documentation of these requirements shall be maintained by the permittee for the duration of time the affected 

emissions unit(s) is (are) covered under the General Permit.

The following is a summary of the five eligibility criteria. See Section 2.0 for detailed instructions to determine which 

criterion applies for your specific action:

Criterion A:

No federally-listed threatened or endangeredspecies or designated critical habitat(s) of such species are likely to occur

within the action area for your project.1

 1 Action area means all areas to be affected directly or indirectly by your project and may be broader than the immediate project 

area [See, e.g., 50 CFR 402.02].

Gasoline Dispensing Facilities within California Page 14 of 23

Criterion B:

Federally-listed threatened or endangeredspecies or their designated critical habitat(s) are likely to occur within the action 

area of your source, but the construction and operation of your new minor source or construction and operation of the 

modification to your existing minor source is not likely to adversely affect listed threatened or endangered species or

critical habitat. This determination may include consideration of any air pollution controls or other changes to the 

construction and/or operation of your new or modified source that you will adopt to ensure that construction, modification 

and operation of your new or modified source are not likely to adversely affect listed species or critical habitat. To 

make this certification, you must include the following in your Request for Coverage documentation: (1) identify any 

federally listed species and/or designated critical habitat located within the action area of your source; (2) the distance

between yoursite and the listed species or designated critical habitat (in miles); and (3) any other information 

necessary (e.g., a detailed map of the action area and supporting justification) to show that the 

construction/modification and operation of your new or modified source are not likely to cause any adverse effects to the 

listed threatened or endangered species or their critical habitat. 

Criterion C:

Coordination between you and the Service(s) has been concluded and has addressed the effects of your new or 

modified minor source’s construction/modification and operation on federally-listed threatened or endangered species

and federally-designated critical habitat. The coordination must result in a written concurrence from the relevant

Service(s) that your new or modified minor source’s construction/modification and operation are not likely to adversely

affect listed species or critical habitat. You must include copies of the correspondence between yourself and the

Service(s) with your submittal.

Criterion D:

Consultation between another Federal Agency and the Service(s) undersection 7 of the ESA has been concluded. The

consultation must have addressed the effects of your minor source’s construction/modification and operation on

federally-listed threatened or endangered species and federally-designated critical habitat. The result of this

consultation must be either:

1. A biological opinion that concludesthat the action in question (taking into account the

federally-listed species and federally-designated critical habitat. You must include copies of the incidental take permit 

and associated documentation and correspondence between yourself and the Service(s) with your submittal.

2.0 Determining Which Criterion Applies

To qualify for the General Permit, you need to meet one of the five criteria listed above. You must follow the

proceduresin Steps 1 through 5 below to determine the listed species criterion, if any, under which your project is

eligible for permit coverage.

Step 1 - Determine if Previous or Separate Assessments Have Already Addressed Your Source.

You should first determine whether you are eligible to select either Criterion D or E based on an ESA section 7 

consultation previously completed by another Federal Agency (Criterion D) or an ESA section 10 permit (Criterion E) 

issued by the Service(s) as follows: 

Meeting Criterion D: If consultation under section 7 of the ESA has been concluded in connection with another Federal 

Agency’s involvement with your source, you may be eligible to select Criterion D. To be eligible to select Criterion D, you 

must confirm that all the following are true: 

• A consultation between a Federal Agency and the Service(s) under section 7 of the ESA has been concluded. 

Consultations can be either formal or informal, and would have occurred in connection with a separate action by 

a separate Federal Agency (e.g., as part of a separate Federal Agency’s authorization for you to construct or 

operate your business in Indian country). The consultation must have addressed the effects of the construction, 

modification and operation of your new or modified source on all federally-listed threatened or endangered 

species and all federally-designated critical habitat in your action area. The result of this consultation must be 

either: 

a. A biological opinion that concludes that the construction, modification and operation of your new or 

modified source is not likely to jeopardize the continued existence of any listed species, nor result in the 

destruction or adverse modification of any designated critical habitat. The consultation must have included 

consideration of the effects of your facility’s emissions and other related activities on all listed species and 

designated critical habitat in your action area; or 

b. Written concurrence (e.g., letter of concurrence) from the applicable Service(s) with a finding that the

construction, modification and operation of your new or modified source are not likely to adversely affect 

listed species or designated critical habitat. The consultation must have included the effects of your 

facility’s emissions and other related activities on all the listed species and designated critical habitat in 

your action area. 

• The consultation remains current, in accordance with 50 CFR §402.16; or, if re-initiation of consultation is 

required (e.g., due to a new species listing or critical habitat designation or new information), such reinitiated 

consultation is concluded, and the result of the consultation is consistent with the statements above. Attach a 

copy of any consultation re-initiation documentation from the Service(s) or other consulting Federal Agency. 

If all of the above are true, you may select Criterion D. You must also provide a description of the basis for the 

criterion selected. In your submittal you must also provide the Biological Opinion (or Public Consultation Tracking 

System tracking number) or concurrence letter and any other documentation supporting your determination.

If any of the above is not true, you may not select Criterion D. For example: if the biological opinion or written 

concurrence from the Service(s) did not include the effects of your source’s air emissions or other-related activities as

described above; or if the previous consultation covered some but not all of the listed species or critical habitat in your 

action area; or if the consultation is no longer current (e.g., due to new species listings); then you are not eligible under 

Criterion D.

Meeting Criterion E: You have obtained an incidental take permit under section 10 of the ESA, and this permit 

addresses the effects of the construction/modification and operation of your new or modified source on federallylisted species and designated critical habitat in your action area. 

You may rely on a section 10 permit that you have previously obtained so long as it addresses the 

construction/modification and operation of your new or modified source and all federally-listed species and 

designated critical habitat in your action area. (Note: If you do not hold a section 10 permit already, you can 

consider obtaining one; however, it may be more efficient to instead meet the requirements for Criterion A, B or C 

as described in Steps 2 – 5.)

If you choose to apply for a new section 10 permit, you must follow applicable Service procedures (see 50 CFR

§17.22(b)(1) for FWS and §222.22 for NMFS). Application instructionsfor section 10 permits for FWS and NMFS can be

obtained by accessing the FWS and NMFS websites (http://www.fws.gov and http://www.nmfs.noaa.gov) or by

contacting the appropriate FWS and NMFS regional office. 

If the above is true, you may select Criterion E. You must also provide a description of the basis for the criterion 

selected. In your submittal you must provide a copy of the permit issued by the Service(s). 

If the above is not true, you may not select Criterion E at this time and must proceed to Step 2. For example, if a 

permit has been issued under section 10 of the ESA, but the permit did not consider the effects of the facility’s air 

emissions and/or emission-related activities on all federally listed species and designated critical habitat on your 

species list, you are not eligible under Criterion E.

Step 2 - Determine if Listed Threatened or Endangered Species or their Designated Critical Habitat(s) are Likely to

Occur within the Action Area of your Minor Source.

You must determine,to the best of your knowledge, whetherspeciesfederally listed as either threatened or

endangered, or their designated critical habitat(s), are located within the action area of your minor source.2 This is a twostep process. The first step is to determine your action area. When defining the boundaries of your action area, you should 

take into account the following criteria:

• Ground disturbance – Effects during construction, maintenance and operation of the facility should be 

considered.

• Changes in water quality/quantity (both surface and groundwater) – This would include effects that may extend 

far beyond the footprint of the facility. An example may be stormwater runoff from impervious surfaces 

(containing sediments or other contaminants) on the site that may reach water bodies (including ditches that 

empty into water bodies) some distance from a facility. All receiving water bodies that could receive pollutants 

from the facility’s construction, maintenance, or operation should be included in the action area.

• Air Quality Impacts – Effects during construction, maintenance and operation of the facility should be 

considered.

• Lighting effects – Effects during construction, maintenance and operation of the facility should be considered.

• Noise Disturbance – Effects during construction, maintenance and operation of the facility should be considered.

Note: If you have questions about determining the extent of the action area, you should coordinate with the 

local Service field office as noted below. If site-specific conditions exist such that the action area would be 

limited to the facility footprint, but that fact may not be obvious from a map or figure, submit a narrative 

description of the action area in addition to a map for evaluation of the action area selected. To determine

the field office that correspondsto your project site, visit: 

http://www.fws.gov/endangered/regions/index.html and http://www.nmfs.noaa.gov/ (under the left tab for

“Regions”).

After determining the boundaries of the action area, you will next determine if listed species and/or critical habitat are

expected to exist there. Relevant sources of information regarding the locations of listed species and critical habitats are 

often organized along county and/or township lines. You should thus first identify the counties and/or townships within 

which your action area is located. You would then consult relevant sources of information regarding the locations of listed 

species and critical habitats. The local offices of the FWS and NMFS often maintain lists of federally listed threatened or 

endangered species on their Internet sites. For FWS terrestrial and aquatic species information, you can use the FWS online mapping tool, the Information, Planning, and Consultation System, located at http://www.fws.gov/ipac/.

In most cases, listed species and designated critical habitat lists will allow you to determine if any such species or

habitat exists in your county or township. You can also find critical habitat designations and associated

requirements at 50 CFR Parts 17 and 226 (see http://www.access.gpo.gov). You may also use the FWS Critical 

Habitat Portal (see http://criticalhabitat.fws.gov/crithab/).

• If there are no listed species and/or critical habitat in the counties/townships where your action area is 

located you may select Criterion A. You must also provide a description of the basis for the criterion selected

and provide documentation supporting the criterion selected in your submittal.

• If there are listed species and/or critical habitat in the counties/townships in your action area, you should

contact your local FWS or NMFS office to determine if the listed species are known to exist within the 

specific action area of your minor source and if any designated critical habitat areas overlap the action area of 

your minor source.

o If your local FWS or NMFS office indicatesthat these species and/or critical habitat could exist within the 

action area of your minor source, you must do one of the following to determine if the species and/or 

critical habitat may actually be present in or may use your action area:

 Conduct visual inspections. This method may be particularly suitable for sites that are smaller in 

size or located in non-naturalsettings such as highly urbanized areas or industrial parks where

there is little or no natural habitat.

 Conduct a formal biologicalsurvey. In some cases, particularly for larger sites, biologicalsurveys

may be an appropriate way to assess whetherspecies are located within the action area of your

minor source. Biological surveys are frequently performed by environmental consulting firms. A

biological survey may in some cases be useful to conduct in conjunction with Steps 3, 4 or 5 of

these instructions.

• If, after performing one or more of the assessments above, you determine that there are no listed species 

or critical habitat in your action area, you may select Criterion A. You must also provide a description of the

basis for the criterion selected and provide documentation supporting the criterion selected in your submittal.

• If listed species or critical habitat are located in your action area, then proceed to step 3.

Step 3 - Determine if the Construction/Modification or Operation of Your New or Modified Minor Source is Likely

to Adversely Affect Listed Threatened or Endangered Species or Designated Critical Habitat.

If in Step 2 you determine, based on communication with your local FWS or NMFS office, or otherwise,that listed

species and/or critical habitat could exist within the action area of your new or modified minor source, you must

next assess whether the construction/modification or operation of your new or modified minor source islikely to adversely

affect listed threatened or endangered species or designated critical habitat.

Potential adverse effects from construction/ modification and operation activitiesinclude direct and indirect effects and 

could include, but are not limited to, the following:

• Habitat Disturbance. Surface disturbance activities such as excavation,site development, grading, and associated 

light and noise may adversely affect listed species or their habitat. 

• Operation of the Source. Source operations could result in additional traffic, noise and light that could affect 

species or habitat.

• Water-Related Impacts. Changes in water usage or water discharges may affect listed species or their habitat. 

• Air Emission Impacts. Increases in emission of certain pollutants may in certain cases affect vegetation growth 

patterns that can affect listed species or their habitat. 

The scope of effectsto consider will vary with each site and project. If you are having difficulty determining whether

your project is likely to adversely affect listed species or critical habitat, or one of the Services has already raised

concernsto you, you should contact the appropriate office of the FWS or NMFS for assistance.

• If adverse effectsto listed threatened or endangered species or their critical habitat are not likely, then you

may select Criterion B. You must provide the following specific information with your submittal:

1 . The federally listed species and/or designated habitat that are located within the action area of your minor 

source;

2 . The distance between your site and the listed species or designated critical habitat (in miles); and

3 . Any other information necessary to show that the construction/modification and operation of your source are 

not likely to cause any adverse effects to the listed threatened or endangered species or their critical habitat. 

• If adverse effects to listed threatened or endangered species or their critical habitat are likely, you must 

follow Step 4 below.

Step 4 - Determine if Measures Can Be Implemented to Avoid Adverse Effects.

If you determine in Step 3 that adverse effects from the construction/modification or operation of your new or 

modified minor source are likely to occur, you can still select eligibility Criterion B if you undertake appropriate

measuresto avoid or eliminate the likelihood of adverse effects prior to seeking coverage under the General Permit.

These measures may involve relatively simple changesto construction activitiessuch as re-routing construction to

bypass an area where species are located, relocating source activities, or modifying the “footprint” of the site.

• If you are able to implement appropriate measuresto avoid the likelihood of adverse effects, then you may

select Criterion B. The measures you adopt to avoid or eliminate adverse effects must be implemented for the

duration of the construction/modification and operation of your new or modified minor source and your

coverage under this General Permit. You must also provide a description of the basis for the criterion selected,

and the following specific information on your Request for Coverage Form: (1) the federally listed species

and/or designated habitat that are located within the action area of your minor source; (2) the distance between

your source and the listed species or designated critical habitat (in miles); and (3) what steps were or will be 

taken to avoid the likelihood of adverse effects.

• If you cannot determine sufficient measuresto implement to avoid the likelihood of adverse effects, you

must follow the proceduresin Step 5.

Step 5 - Coordinate with the Service(s).

If in Step 4 you cannot determine sufficient measuresto avoid the likelihood of adverse effects, you must contact the

applicable Service(s). You may still be eligible for coverage under the General Permit if the likely adverse effects can be

addressed through meeting Criterion C.

• Criterion C: You have coordinated with the Service(s) and have addressed the effects of the 

construction/modification and operation of your new or modified minor source on federally-listed threatened

or endangered species and federally-designated critical habitat. The Service(s) must provide written 

concurrence that the construction/modification and operation of your new or modified minor source is not

likely to adversely affect listed species or critical habitat.

o If you have obtained the Service(s) written concurrence as described above, then you may select Criterion C.

As part of your submittal, you must provide a description of the basis for the criterion selected and must

include copies of the correspondence between you and the applicable Service(s).

Appendix B – Historic Property Screening Process

1.0 Background

The purpose of this appendix is to assist you in completing the

screening procedure for addressing historic properties that are 

either listed on, or eligible for listing on, the National Register for 

Historic Places prior to submitting your Request for Coverage under 

the General Air Quality Permit for New or Modified Minor Source 

Gasoline Dispensing Facilities in Indian Country within California

(General Permit). In order to be eligible for coverage under the 

General Permit, you must demonstrate that you qualify under one

of the criteria listed in this appendix with respect to the protection

of historic properties. The EPA must provide confirmation that you 

satisfactorily completed this screening procedure in order for you 

to be eligible for coverage under the General Permit.

To address any issues relating to historic properties, the EPA has

developed the screening process in this appendix to enable source 

owners/operatorsto: (1) appropriately consider the potential

impacts, if any, resulting from the construction, modification, and/or operation of a new or modified emission source on

historic properties and, (2) if applicable, determine whether actions can be taken to mitigate any such impacts. Although

each decision that a specific minor source meets the requirements for coverage under this General Permit does not constitute

a separate Federal undertaking, the screening processin this appendix provides an appropriate site-specific means of 

addressing historic property issues in connection with coverage under the General Permit.

If the impacts from your source have already been reviewed under another Federal agency’s approval process (e.g., the 

Bureau of Indian Affairs authorizing operation of your source in Indian country) then documentation from that review 

may satisfy the requirements of this section. In some cases, the review by another agency will have evaluated the 

impacts from site disturbance activities (e.g., site clearing), but not from air emissions. In such cases supplemental 

evaluation may be required to complete the analysis.

2.0 Instructions for Source Owners/Operators

You are required to follow the screening process in this appendix to determine if the construction, modification or 

operation of a new or modified minor source of air pollutants on your site has the potential to cause effectsto historic

properties, and whether or not you need to contact your State Historic Preservation Officer (SHPO), Tribal Historic 

Preservation Officer (THPO), or other tribal representative for further information. You must satisfactorily complete this

screening process to be eligible for coverage under the General Permit. The following four steps describe how

applicants can meet the historic property requirements under this permit.

Key Terms

Historic property- prehistoric or historic districts,

sites, buildings, structures, or objects that are

included in or eligible for inclusion in the National

Register of Historic Places, including artifacts,

records, and remains that are related to and located

within such properties

SHPO – The State Historic Preservation Officer for 

a particular state

THPO or Tribal representative – The Tribal Historic 

Preservation Officer for a particular Tribe or, if there is 

no THPO, the representative designated by such Tribe

for NHPA purposes

Step 1 - Have prior professional cultural resource surveys or other evaluations determined whether

historic properties exist in the area of your proposed source? Or, have prior earth disturbances precluded

the existence of historic properties in the area of your proposed source?

If it has already been determined that no historic properties exist in the area of your proposed source based

on available information, including information that may be provided by your applicable SHPO, THPO, or

other tribal representative,then you may submit the appropriate documentation of “no historic properties 

affected” with your submittal, and no furtherscreening steps are necessary.

Similarly, if earth disturbancesthat have occurred prior to your project have eliminated the possibility that historic

properties exist on your site or in the area affected by your new or modified minor source, then you may submit the 

appropriate documentation of “no historic properties affected” with your submittal, and no furtherscreening steps are

necessary.

During the EPA’s review process, the SHPO, THPO, or other tribal representative may request that the EPA deny 

coverage under the General Permit based on concerns about potential adverse impacts to historic properties. The EPA 

will evaluate any such request and notify you if any additional information is needed to address adverse impacts to 

historic properties.

Step 2 - If you are constructing or modifying a minor source of air pollutants, as defined in 40 CFR §49.152, you

must determine if the construction, modification or operation of the minor source will have an effect on

historic properties.

If your answer to the questionsin Step 1 is “no,” then you must assess whether the activitiesrelated to the

construction, modification or operation of your new or modified minor source will have an effect on historic properties. 

Activities that could have an adverse effect on historic properties could include, for example: 

• Excavations;

• Demolitions of existing buildings;

• Construction of foundations (e.g., for buildings, tanks or stacks);

• Installations of underground tanks;

• Addition of impervious surfaces; and

• Increases in truck traffic during excavation, demolition, or construction.

Note: This list is not intended to be exhaustive. Other activitiesthat are not on this list may involve earth-disturbing

activities and must also be examined for their potential to affect historic properties. For more information, go to the 

National Park Service, National Register of Historic Places database found at 

http://www.nps.gov/history/nr/research/index.htm. 

The assessment may be based on a site map of your source and an analysis of historicalsources, knowledge of the area, 

an assessment of the types of activities you are engaging in, considerations of any controls and/or management

practices you will adopt to ensure that your activities will not have an effect on historic properties, and any other

relevant factors.

If you determine based on this assessmentthat the activities related to the construction, modification or operation of 

your new or modified minor source will not cause effectsto historic properties, then you may submit the appropriate 

documentation of “no historic properties affected” with your submittal, and no furtherscreening steps are necessary.

During the EPA’s review process, the SHPO, THPO, or other tribal representative may request that the EPA delay your 

coverage under the General Permit based on concerns about potential adverse impacts to historic properties. The EPA 

will evaluate any such request and notify you if any additional information is needed to address adverse impacts to 

historic properties.

If you are installing or modifying equipment that has the potential to have an adverse effect on historic properties, then

you must proceed to Step 3.

Step 3 - If you are constructing or modifying a minor source and you have not satisfied the conditionsin Steps

1-2, you must contact and consult with the appropriate historic preservation authorities.

Where you are constructing or modifying a minor source and you cannot determine in Step 2 that this activity will not

have effects on historic properties,then you must contact the relevant SHPO, THPO, or other tribal representative to 

request their views as to the likelihood that historic properties may be adversely affected by the construction, 

modification or operation of your new or modified minor source.

Note: Addressesfor SHPOs and THPOs may be found on the Advisory Council on Historic Preservation’s(ACHP’s) website

(http://www.achp.gov/programs.html). In instances where a tribe does not have a THPO, you should contact the

appropriate Tribal government office designated by the tribe for this purpose when responding to this permit eligibility 

condition.

You must submit the following minimum information in order to properly initiate your request for information:

1. Project name (i.e., the name or title most commonly associated with your project);

2. A narrative description of the project;

3. Name, address, phone and fax number, and email address (if available) of the operator;

4. Most recent U.S. Geological Survey map section (7.5 minute quadrangle) showing actual project location and 

boundaries clearly indicated; and

5. Sections of site map that show locations where activities might cause an adverse effect on historic properties.

Without submitting this minimum information, your request cannot be considered. You will need to provide the

SHPO, THPO, or other tribal representative a minimum of 15 calendar days after they receive these materialsto

respond to your request for information about your project. You are advised to get a receipt from the post office or 

other carrier confirming the date on which your letter was received.

If you do not receive a response within 15 calendar days after receipt by the SHPO, THPO, or other tribal representative

of your request, then you may indicate this in your submittal, and no furtherscreening steps are necessary.Or, if the

applicable SHPO, THPO, or other tribal representative respondsto your request with an indication that no historic

properties will be adversely affected by the construction or modification of your minor source, then you may submit the 

appropriate documentation of “no adverse effects” with your submittal, and no furtherscreening steps are necessary.

If within 15 calendar days of receipt of your request the applicable SHPO, THPO, or other tribal representative 

responds with a request for additional information or for further consultation regarding appropriate measures for 

treatment or mitigation of effects on historic properties caused by the construction, modification or operation of your 

minor source, you must comply with this request and proceed to Step 4.

During the EPA review process, the SHPO, THPO, or other tribal representative may request that the EPA place a hold 

on authorization based on concerns about potential adverse impacts to historic properties. The EPA will evaluate any 

such request and notify you if any additional information is needed to address adverse impacts to historic properties 

before continuing review of your Request for Coverage under the general permit.

Step 4 - Consultation with your applicable SHPO, THPO, or other tribal representative.

If, following your discussions with the appropriate historic preservation authoritiesin Step 3, the applicable SHPO, THPO,

or other tribal representative requests additional information or further consultation, you must respond with such

information or consult to determine impacts and appropriate measures to mitigate such impacts to historic properties

that may be caused by the construction, modification or operation of your new or modified minor source site. If after 

consultation it is determined that there will be no adverse effects to historic properties, then you may submit the 

appropriate documentation of “no adverse effects” with your submittal, and no further screening steps are necessary. If as

a result of your discussions with the applicable SHPO, THPO, or tribal representative, you enter into, and comply with, a 

written agreement regarding treatment and/or mitigation of impacts on yoursite, then you may submit the appropriate 

documentation of “adverse effects” with your submittal.

If, however, agreement on an appropriate treatment or mitigation plan cannot be reached between you and the SHPO,

THPO, or other tribal representative within 30 days of your response to the SHPO, THPO, or other tribal

representative’srequest for additional information or further consultation, you may submit your screening process 

documentation, but you must indicate that you have not negotiated measuresto avoid or mitigate such effects. You

must also include the following with your submittal:

1. Copies of any written correspondence between you and the SHPO, THPO, or other tribal representative; and

2. A description of any significant remaining disagreements as to mitigation measures between you and the SHPO, 

THPO, or other tribal representative.

During the EPA’s review period, the SHPO, THPO, ACHP or other tribal representative may request that the EPA place a 

hold on confirmation based upon concerns regarding potential adverse effects to historic properties. The EPA, in 

coordination with the SHPO, THPO, ACHP or other tribal representative, will evaluate any such request and notify you if 

any additional measures to address potential adverse effects to historic properties are necessary.
