Request for Coverage under the General Air Quality Permit for New or Modified
Minor Source Compression Ignition Engines in Indian Country
Last Modified: July 1, 2016
Version 1.0
This Request for Coverage under the General Air Quality Permit for New or Modified True Minor Source Compression
Ignition Engines in Indian Country applies to the construction of a new minor source stationary compression ignition
engines or the modification of an existing minor source stationary compression ignition engines in Indian country that
meet certain restrictions. The U.S. Environmental Protection Agency (EPA) is making two engine permits available:
One General Permit is for facilities that have non-emergency compression ignition internal combustion engines
and one is for facilities that have non-emergency spark ignition internal combustion engines;
The engine General Permits are intended for sources that consist primarily of non-emergency engines used, for
example, to produce electrical power or pump water; and
The engine General Permits were not developed to apply to engines that are a part of a larger source category,
such as the oil and gas industry or the other source categories for which the EPA has developed general permits
or permits by rule. These source categories are not prohibited from applying for the engine General Permits, but
may find other permitting options are available that provide greater flexibility.
If you have both compression ignition AND spark-ignition non-emergency stationary engines present at your facility,
then you are not eligible for this General Permit and should consult your reviewing authority for obtaining a site-specific
permit.
This Request for Coverage covers compression ignition stationary internal combustion engines (ICE) that convert heat
energy into mechanical work and are not mobile. This source category does not include combustion turbines or nonroad
engines (mobile ICE) such as forklifts, off-highway mobile cranes, bulldozers, and lawnmowers. Stationary ICE includes
reciprocating ICE, rotary ICE, and other ICE, except combustion turbines as noted. This category covers both nonemergency and emergency generator stationary ICE. This general air quality permit does not apply to mobile engines
that remain in place for 12 months or less. Stationary engines include: (1) nonroad engines that are portable or
transportable and that remain at a single location for 12 months or longer and (2) nonroad engines that are located at
seasonal sources and operate during the annual operating season for the source.
This permit is available in Indian country for use by true minor and synthetic minor sources. The engines general permits
are not intended to cover engines in the oil and natural gas production and natural gas processing segments of the oil
and natural gas sector.
You qualify to apply for coverage under this general permit if you meet all of the following criteria:
You plan to construct a new true or synthetic minor source of engines or to modify an existing minor source of
engines;
You are not planning to construct or modify a major source of engines;
Your new or modified minor source of engines is located within Indian country;
Your new or modified minor source of engines is not located in a severe or extreme ozone nonattainment area;

power of all emergency generator engines that is below 1,000 hp in attainment areas or 500 hp in ozone
nonattainment areas classified as serious or lower (regardless of fuel type). All emergency engines must be
emergency generator engines used solely for supplying electrical power during power outages;
If your new or modified minor source of engines has auxiliary heaters, they have a combined maximum heat input
of no greater than 10 million British thermal units per hour (MMBtu/hr) in attainment, unclassifiable or
attainment/unclassifiable areas or 5 MMBtu/hr in marginal, moderate or serious ozone nonattainment areas;
You demonstrate that you meet 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
You have followed the screening process in Appendix B to determine if the construction, modification or operation of
your new or modified true minor source of air pollutants has the potential to cause effects to historic properties
(pursuant to the National Historic Preservation Act (NHPA)).
The reviewing authority retains discretion to terminate your coverage under the General Permit and require a sourcespecific permit even if the above criteria are met. Reasons the reviewing authority may terminate a permitted source’s
coverage under the General Permit include:

Federally-listed threatened or endangered species 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 your site 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) under section 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 concludes that the action in question (taking into account the effects of your
source’s construction/modification and operation) is not likely to jeopardize the continued existence of
listed species, or result in the destruction or adverse modification of critical habitat; or
2. Written concurrence from the applicable Service(s) with a finding that the source’s
construction/modification and operation are not likely to adversely affect federally-listed species or
federally-designated critical habitat.
You must include copies of the relevant documentation cited above in your submittal.
Criterion E:
You have obtained an incidental take permit from the Service(s) under section 10 of the ESA in connection with your
construction/modification and operation activities, and this permit addresses the effects of the source on relevant
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.

Determining Which Criterion Applies
2.0
To qualify for the General Permit, you need to meet one of the five criteria listed above. You must follow the
procedures in 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.

EPA Form No. 5900-367 OMB
Control No. 2060-0003
Approval expires xx/xx/2023
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 instructions for 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, whether species federally 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.

OMB Control No. 2060-0003
Approval expires xx/xx/2023
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 corresponds to 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 indicates that 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-natural settings such as highly urbanized areas or industrial parks where
there is little or no natural habitat.
Conduct a formal biological survey. In some cases, particularly for larger sites, biological surveys
may be an appropriate way to assess whether species 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 is likely to adversely
affect listed threatened or endangered species or designated critical habitat.
Potential adverse effects from construction/ modification and operation activities include 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 effects to 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
concerns to you, you should contact the appropriate office of the FWS or NMFS for assistance.
If adverse effects to 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
measures to avoid or eliminate the likelihood of adverse effects prior to seeking coverage under the General Permit.
These measures may involve relatively simple changes to construction activities such 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 measures to 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 measures to implement to avoid the likelihood of adverse effects, you
must follow the procedures in Step 5.
Step 5 - Coordinate with the Service(s).
If in Step 4 you cannot determine sufficient measures to 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
Compression Ignition Engines in Indian Country. 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 under
the NHPA.
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
To address any issues relating to historic properties, the EPA has
THPO or Tribal representative – The Tribal Historic
developed the screening process in this appendix to enable source
Preservation Officer for a particular Tribe or, if there is
owners/operators to: (1) appropriately consider the potential
no THPO, the representative designated by such Tribe
impacts, if any, resulting from the construction, modification, and/or
for NHPA purposes
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 process in 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 effects to 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 may not submit your Request
for Coverage under the General Permit until you have completed this screening process and obtained confirmation of
satisfactory completion from the EPA. The following four steps describe how applicants can meet the historic
property requirements under this permit.

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 further screening steps are necessary.
Similarly, if earth disturbances that 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 further screening steps are
necessary.
During the 30-day period following receipt of your screening process documentation by the EPA, 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 questions in Step 1 is “no,” then you must assess whether the activities related 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 activities that 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 historical sources, 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 assessment that the activities related to the construction, modification or operation of
your new or modified minor source will not cause effects to historic properties, then you may submit the appropriate
documentation of “no historic properties affected” with your submittal, and no further screening steps are necessary.
During the 30-day period following receipt of your screening process documentation by the EPA, 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 conditions in 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: Addresses for 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.
2.
3.
4.
Project name (i.e., the name or title most commonly associated with your project);
A narrative description of the project;
Name, address, phone and fax number, and email address (if available) of the operator;
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 materials to
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 further screening steps are necessary. Or, if the
applicable SHPO, THPO, or other tribal representative responds to 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 further screening 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 30-day period following receipt of your screening process documentation by the EPA, 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 authorities in 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 your site, 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’s request for additional information or further consultation, you may submit your screening process
documentation, but you must indicate that you have not negotiated measures to 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 30-day period following receipt of your submittal by the EPA, 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.
