Questionnaire for Requesting Coverage under the General Air Quality Permit for
New or Modified Minor Source Hot Mix Asphalt Plants in Indian Country

Last Modified: February 13, 2017
Version 1.0

Does the General Permit apply to my facility?

The following questionnaire is intended to help you, the facility owner or operator, determine whether or not you
are eligible for the General Air Quality Permit for New or Modified Minor Source Hot Mix Asphalt Plants in Indian
Country. You are not required to complete this questionnaire and it is not necessary to apply for the General Air
Quality Permit for New or Modified Minor Source Hot Mix Asphalt Plants. This questionnaire does not cover all of the
General Air Quality Permit requirements and does not guarantee approval of a minor source preconstruction permit
underthis program. This General Air Quality Permit is available to true minor and synthetic minor sources of
regulated New Source Review (NSR) pollutants.

Description of Hot Mix Asphalt Plants

A hot mix asphalt plant is a facility that manufactures hot mix asphalt by heating and drying aggregate and mixing
with asphalt cements, and is comprised only of any combination of the following activities: dryers, liquid asphalt
storage tanks, fuel oil storage tanks, auxiliary heaters (including hot oil heaters), material storage handling and
transfer systems, generators, storage bins/silos, storage piles, and haul roads.

About this Questionnaire

The questions focus on general information pertaining to your existing or future hot mix asphalt plant.The
questionnaire is not meant to be exhaustive and only requires knowledge of basic facility information, including the
maximum capacity of the units, production rate, and fuel usage.

You should continue with this Questionnaire if you meet all of the following criteria:

•	You plan to construct a new true or synthetic minor source batch or drum hot mix asphalt plant OR
planto modify an existing minor source batch or drum hot mix asphalt plant;

•	You are not planning to construct or modify a major source batch or drum hot mix asphalt plant;

•	Your new or modified minor source hot mix asphalt plant is located within Indian country;

•	Your hot mix asphalt operation will be co-located with your stone quarrying, crushing and
screeningoperation (this is not a requirement to qualify for this General Permit);

•	You do not know whether your facility needs a permit, or if you do not know the attainment status of your
area and you want to find out whether or not you should apply for the General Permit for a hot mix asphalt
facility; and

•	You intend to satisfy the processes that the EPA has made available in the application documents forthis
General Permit to address threatened and endangered species and historic properties under the
Endangered Species Act and the National Historic Preservation Act, respectively.

More Information

The definition of a "modification" and "Potential to Emit" (or "PTE") can be found at 40 CFR 49.152(d) and inthe
"Instructions" document. Additional information on the applicability of the Federal Indian Country Minor NSR Rule
can be found at 40 CFR 49.153.

Information on the ozone attainment status of the area where your facility is located can be found at:
https://www.epa.gov/green-book. You may also contact your reviewing authority for information on your
attainment status.

Please contact your reviewing authority if you have questions or need assistance. A list of reviewing authorities,
their areas of coverage, and contact information can be found in Attachment D to the General Air Quality Permit
for Minor Source Hot Mix Asphalt Plants or visit: https://www.epa.gov/tribal-air/tribal-minor-new-source-review.

Sources eligible for the General Permit for New or Modified Minor Source Hot Mix Asphalt Plants may also be
subjectto federal standards under 40 CFR 60 Subpart I - Standards for Performance for Hot Mix Asphalt Facilities; 40
CFR60 Subpart Mil - Standards of Performance for Stationary Compression Ignition Internal Combustion Engines; and
40 CFR63 Subpart ZZZZ - National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating
Internal Combustion Engines. The conditions applicable to sources seeking coverage under this General Permit are
intended to be generally consistent with the requirements in these regulations; however, compliance with the
applicable requirements is required independent of the conditions in the General Permit, and not all requirements
applicable under Subparts I, Nil, and ZZZZ are necessarily included in the General Permit. The Background Document
forthe General Permit identifies the specific requirements in these Subparts that are intended to be included in the
General Permit.

Additional Information about Co-Located Stone Quarrying, Crushing and Screening Operations:

If you otherwise qualify for this General Permit and intend to be co-located with your stone quarrying, crushing and
screening facilities operation you may still qualify for the General Permit if:

•	The combined potential emissions of the two operations are below all of the applicable Major NSR
thresholds and you obtain the General Permit or a site-specific permit for your stone quarrying, crushing
and screening facilities operation; or

•	The combined potential emissions of the two operations are below all the applicable major NSR
thresholds, but you elect to take more restrictive throughput and fuel use limits, those in Conditions 17.
and 20.b. of the General Permit, so that combined potential emissions of the two operations are below
100 tons peryear (tpy) for regulated NSR pollutants, and you obtain the Stone Quarrying, Crushing and
Screening Facilities General Permit with the elective limits for co-located operations. This option is not
available in serious, severe or extreme ozone nonattainment areas or serious carbon monoxide (CO)
nonattainment areas.

Please contact your reviewing authority for additional information.

Questionnaire for Hot Mix Asphalt Plants

Part 1: Does my Hot Mix Asphalt Plant Need or Qualify for a Minor Source Permit?

The following questions are meant to determine whether or not your asphalt plant needs or qualifies for the general
permit.

1.	Will the PTE of your facility be less than 250 tpy for particulate matter (PM, PMio, or PM2.5), volatileorganic
compound (VOC), nitrogen oxides (NOx), CO, and sulfur dioxide (S02), each individually? The emissions from
your facility may be calculated using the PTE calculator provided at https://www.epa.gov/tribal-air/tribal"
minor-new-source-review. Be sure to include all existing, new, and modified emission units at yourfacility.

~ Yes ~ No

If you answered 'No/ you do not qualify for the General Permit, please contact your reviewing authority to
apply for a site-specific permit. If you answered 'Yes/ continue on to the next question. A synthetic minor
source that agrees to the enforceable conditions in the General Permit and is below the threshold above
should answer 'Yes.'

2.	Will the PTE of your new facility or the increase in potential emissions from your modified existing facility be
equal to or above the applicable minor NSR thresholds listed below for ANY pollutant? The potential emissions
from your facility may be calculated using the PTE calculator provided at: https://www.epa.gov/tribal-air/5-

source-categories-hot-mix-asphalt-plants-final-rule. Be sure to include all new or modified emission units at
yourfacility.

Conclusion

If you answered 'Yes' or 'Not Applicable' to each question in Part 3, your facility may qualify for coverage underthe
Hot Mix Asphalt Plants General Air Quality Permit. If you believe based upon your answers in this questionnaire that
your new or modified hot mix asphalt plant qualifies for a General Air Quality Permit for New or Modified Minor
Source Hot Mix Asphalt Plants, please submit a Request for Coverage to your reviewingauthority.

If you answered 'No' to any of these questions, your facility may not qualify for coverage under the Hot Mix Asphalt
Plants Air Quality Permit. Please contact your reviewing authority to confirm that your facility will not qualify forthis
General Permit.
