## Questionnaire for Requesting Coverage under the General Air Quality Permit for

New or Modifed Minor Source Hot Mix Asphalt Plants in Indian Country

Last Modified: March 2 3 , 2015

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 th is 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 under this

progra m. 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 Questionnair e 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 plan to
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

- locate d with your stone quarrying, crushing and screening

operation (thi s is not a requirement to qualif y for this General Permit ) ;

 You d o 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 a pplication documents for th is

Gen eral 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 New or Modified Minor Source Hot Mix Asphalt Plants may also be subject to

federal standards under 40 CFR 60 Subpart I

– Standards for Performance for Hot Mix Asphalt Facilities; 40 CFR 60
Subpart IIII

– S tandards of Performance for Stationary Compression Ignition Internal Combustion Engines ; and 40 CFR 63
Subpart ZZZZ

– N ational 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 gen erally 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, IIII, and ZZZZ are nec essarily 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

.

A dditional Information about Co

- L ocated S tone Q uarrying, 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 emis sions of the two operations are below all the applicable major NSR thresholds,
but y ou 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 o perations are below 100 tons per year ( 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,

seve re or extreme ozone nonattainment areas or serious carbon monoxide ( CO ) nonattainment areas.

Please contact your reviewing authority for additional information.

### Conclusion

If you answered ‘Yes’ or ‘Not Applicable’ to each question in Part 3 , your facility may qualify for coverage under the

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 fo r New or Modified Minor

Source Hot Mix Asphalt Plants , please submit a Request for Coverage to your reviewing authority

.

If you answered ‘No’ to any of these questions, your facility may not qualify for coverage under the Hot Mix Asphalt

Plants Air Qualit y Permit. Please contact your reviewing authority to confirm that your facility will not qualify for this
