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 a General Air Quality Permit for True Minor Source Stone Quarrying, Crushing, and Screening Facilities. You
are not required to complete it and th is questionnaire is not necessary to apply for a General Air Quality Permit for True

Minor Source Stone Quarrying, Crushing, and Screening Facilities . This questionnaire does not cover all of the General
Air Quality Permit requirements and does not guarantee approval of a true minor source preconstruction permit under
this program

.



### Description of Stone Quarrying, Crushing, and Screening Facilities

A Stone Quarrying, Crushing, and Screening Facility is any stationary or portable non

- metallic mineral processing facility

which uses rock crushers, grinding mills, screening operations, bucket elevators, belt conveyors, bagging operations,
storage bins, storage piles, truck loading stations, or r ailcar loading stations to process sand, gravel, or mineral aggregate
or that mines sand and gravel for construction . T his Stone Quarrying, Crushing, and Screening Facilities Questionnaire is

for stone quarrying, crushing, and screening facilities that are not major sources of air pollution and that are located, or
planning to locate, within Indian Country

.



### About this Questionnaire
The questions focus on general information pertaining to your existing or future sand, gravel, rock crushing, and
screening fa cility. The questionnaire is not meant to be exhaustive and only requires knowledge of basic facility
information, including process rates, raw material throughput, and fuel usage

.



### You should continue with this Questionnaire if you:

Plan t o construct a new, true minor source stone quarrying, crushing, and screening facility within Indian

Country ;

Plan t o modify an existing, true minor source stone quarrying, crushing, and screening facility located within
Indian Country ; Have a potential to emit (PTE) less than the New Source Review (NSR) major source thresholds and equal to or
above the minor NSR applicability thresholds. See the “Does my Stone Quarrying, Crushing, and Screening
Facility Need or Qualify for a Minor Source Permit?” section b elow ; Are located in an attainment area for ozone or a marginal or moderate nonattainment area for ozone and, after
the proposed construction or modification project, your facility’s fuel usage for all combustion sources is
projected to be less than a comb ined total of 310,000 gallons of combined fuel consumption in any continuous
rolling 12

- month period ;

Are located in a serious/severe/extreme ozone nonattainment area and, after the proposed construction or
modification project, your facility’s fuel usage for all combustion sources is projected to be less than a combined total of 153,000/80,000/30,000 gallons of diesel fuel over a consecutive 12 month period, respectively ;

A fter the proposed construction or modification project, your uncontrolled facility i s projected to process less
than 10,500,000 tons of raw material throughput in any continuous rolling 12

- month period ; 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 a minor source g eneral permit or a major source permit for a stone quarrying, crushing, and screening facility ; andQuestionnaire: S tone Quarrying, Crushing, and Screening Operations Page 2 of 5

## Questionnaire for Stone Quarrying, Crushing, and Screening Facilities

Part 1: Does my Stone Quarrying, Crushing, and Screening Facility Need or Qualify for a True

Minor Source Permit?
The following questions are meant to determine whether or not your stone quarrying, crushing, and screening facility

qua lifies for a general permit

.

1. Is the PTE of your facility less than 250 tons per year (tpy) for particulate matter (PM, PM 10 , or PM 2.5 ), VOC,
nitrogen oxides (NO X ), carbon monoxide (CO), and sulfur dioxide (SO 2 )? Be sure to include all existing, new, and

modified emission units

.

Yes No

If you answered ‘No

, ’ your source does not qualify for the minor NSR program. Please contact your rev iewing
authority to apply for a site

- specific permit. If you answered ‘Yes

, ’ continue on to the next question

.

2. Is the PTE of your new facility or the emissions increase from your modified existing facility equal to or above the
applicable minor NSR thresholds listed below for ANY pollutant? The emissions from your facility may be
calculated using the PTE calculator provided. Be sure to include all new, modified, or existing emission units
when determining PTE

.

If you answered ‘No

, ’ your source is exempt from the minor NSR program. Please contact reviewing

auth ority to confirm that your facility will not need a permit. If you answered ‘Yes

, ’ continue on to the next

question

.

3. If located in a nonattainment area for any pollutant, is the PTE of your facility for the particular
nonattainment pollutant less than the NSR major source thresholds specified in the table below (based on
nonattainment classification)? Be sure to include all existing, new, and modified emission units

.

### Part 2: What Types of Facilities DO NOT Qualify for thi s General Air Quality Permit for Stone Quarrying, Crushing, and Screening Facili ties?
The following questions are meant to determine whether or not your stone quarrying, crushing, and screening

f acility pro cesses materials that would disqualify it for operating under the General Air Quality Permit for True Minor

Source Stone Quarrying, Crushing, and Screening Facilities. Please only answer the questions that are applicable to
your particular stone quarrying, crushing, and screening f acility

1. Does your facility process metallic materials, radioactive materials, materials that contain asbestos, or materials

intended to be used as fuel?

Yes No

2. Does your facility process minerals for structural clay, clay ceramics, brick, lime manufacturing, phosphate
products, Portland cement, or refractory products?

Yes No

3. Is your facility a sand and/or gravel processing plant that is classified as an industrial sand and gravel plant (SCC

3

- 05

- 027) AND that uses sand/gravel dryers?

Yes No

If you answered ‘No’ to all of these questions, your facility may qualify for coverage under the True Minor Source
Stone Quarrying, Crushing, and Screening Facility General Air Quality Permit , and should continue on to Part 3 of the

Questionnaire

. If you answered ‘Yes’ to any of these questions, your facility likely does not qualify for coverage under the True

Minor Source Stone Quarrying, Crushing, and Screening Facility General Air Quality Permit. Please contact reviewing
authority to confirm that your facility will not qual ify for this permit.



### Part 3 : Does m y Stone Quarrying, Crushing, and Screening Facility Q ualify for a G eneral Air Q uality P ermit ?

facility would qualify for the general permit for minor source stone quarrying, crushing, and screening f acilities

.

1. Will your facility’s maximum raw material throughput be less than 10,500,000 tons in any continuous rolling 12
month period ?

Yes No No t Applicable

2. If the engines used to power the crushers, screeners, and conveyors are stationary engines, will your facility only use diesel fuel/biodiesel to power these engines ? “Stationary” engines include all internal

39,890 gallons and a true maximum vapor pressure less than 4 psi ?

Yes No N o storage tanks at the source

feet from the nearest residence ?

Yes No

7. Do you intend to satisfy the ESA and NHPA requirements according to the method provided in the application
documents for the General Air Quality Permit for True Minor Source Stone Quarrying, Crushing, and Screening

Facilities ?

Yes No



### Conclusion
If you answered ‘Yes’ or ‘Not Applicable’ to each of the questions in Part 3 , you may qualify for coverage under the
Stone Quarrying, Crushing, and Screening Facility General Air Quality Permit

. If you believe based upon your answers
in this questionnaire that your new or modified rock crushing and screening facility qualifies for a General Air Quality

Permit for True Minor Source Stone Quarrying, Crushing, and Screening Facilities, please contact your reviewing
authority to obtain a permit application.

If you answered ‘No’ to any of these questions, your facility may not qualify for coverage under the S tone Quarrying,
Crushing

, and Screening Facility General Air Quality Permit. Please contact your reviewing authority to confirm that
your facility will not qualify for a permit
