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 Minor Source Stone Quarrying, Crushing, and Screening Facilities. You are not
required to complete this questionnaire and it is not necessary to apply for a General Air Quality Permit for New or
Modified 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 minor source preconstruction permit
under this program. This General Air Quality Permit is available to true minor and synthetic minor sources of regulated
New Source Review (NSR) pollutants.

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 railcar loading stations to process rock, sand, gravel, or mineral
aggregate or that mines rock, sand and gravel for construction.

About this Questionnaire

The questions focus on general information pertaining to your existing or future sand, gravel, rock crushing, and
screening facility. 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 meet all of the following criteria:

•	You plan to construct a new true or synthetic minor source stone quarrying, crushing, and screening facility
OR you plan to modify an existing, minor source stone quarrying, crushing, and screening facility;

•	You are not planning to construct or modify a major source stone quarrying, crushing, and screening facility;

•	Your new or modified minor source stone quarrying, crushing, and screening facility is located within Indian
country;

•	Your facility processes non-metallic materials (i.e., sand, gravel, rock or stone);

•	Are seeking to co-locate with a hot mix asphalt operation (this is not a requirement to qualify for the
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 stone quarrying,
crushing, and screening facility; and

•	You intend to satisfy the processes that the U.S. Environmental Protection Agency (EPA) has made available in
the application documents for this General Permit to address threatened and endangered species and historic
properties under the Endangered Species Act and the National Historic Preservation Act, respectively.

Sources eligible for the General Permit for Minor Source Stone Quarrying, Crushing, and Screening Facilities may also be
subject to federal standards under 40 CFR 60 Subpart 000, Standards of Performance for Nonmetallic Mineral
Processing Plants, 40 CFR 60 Subpart Mil, Standards of Performance for Stationary Compression Ignition Internal
Combustion Engines, and 40 CFR 63 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 000, Mil, and ZZZZ are necessarily included in the General Permit. The
Background Document for the General Permit identifies the specific requirements in these Subparts that are intended to
be included in the General Permit.

Additional Information about Co-Located Hot Mix Asphalt Operations:

If you otherwise qualify for this General Permit and intend to be co-located with your hot mix asphalt 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 a general permit or site-specific permit for your hot mix asphalt 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 16. and 19.e of the
General Permit, so that combined potential emissions of the two operations are below 100 tons per year
(tpy) for regulated NSR pollutants, and you obtain the hot mix asphalt plant 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.
