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

New or Modified True Minor Source Concrete Batch Plants in Indian Country

Last Modified: July 2 , 2014

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 New or Modified True Minor Source Concrete Batch Plants . You are not required to complete it and th is questionnaire is not necessary to apply for a General Air Quality Permit for New or

Modified True Minor Source Concrete Batch Plants . 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 Concrete Batch Plants

A Concrete Batch Plant is an operation that combines various ingredi ents to form concrete. T hese inputs may include sand, water, aggregate (rocks, grav el, etc.), fly ash, potash, cement , and cement additives

. A concrete plant can utilize a variety of equipment, including but not limited to: mixers

, cement batchers, aggregate batc hers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, cement silos, batch plant controls, and dust collectors

. T his

Concrete Batch Plants Questionnaire is for both stationary and portable concrete batch plants that are not major sources of air pollution and that are located, or planning to locate, within Indian country

. The General Air Quality Permit

for New or Modified True Minor Source Concrete Batch Plants covers both ready mix plants and central mix plants.



### About this Questionnaire The questions focus on general information pertaining to your existing or future concrete batch plant . The questionnaire is not meant to be exhaustive and only requires knowledge of basic facility information, including

process rates, raw mat erial throughput, and fuel usage

.



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

 Plan t o construct a new, true minor source concrete batch plant within Indian country ;

 Plan t o modify an existing, true minor source concrete batch plant 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 Concrete Batch Plant Need or Qualify for a

Minor Sour ce Permit?” section below ;

 A fter the proposed construction or modification project, your concrete batch plant is pro jected to produce
2,0 00,000 cubic yards or less of concrete per year based on a 12

- month rolling total ;

 Are located in a serious, severe, o r extreme ozone nonattainment area and will not have a non

- emergency engine at you concrete batch plant.

 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 concrete batch plant ; and

 Intend to satisfy the requirements of the Endangered Species Act (ESA) and National Historic Preservation Act (NHPA) according to the procedures attach ed to the Request for Coverage under the General Air Quality Permit

for New or Modified True Minor Source Concrete Batch Plants

.

## Questionnaire for Concrete Batch Plants

Part 1: Does my Concrete Batch Plant Need a True Minor Source Permit? The following questions are meant to determine whether or not your concrete batch plant needs a true minor source 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 ), volatile organic compounds ( VOC ) , nitrogen oxides (NO X ), carbon monoxide (CO), and sulfur dioxide (SO 2 )? The emissions from your facility may be calculated using the PT E calculator provided at http://www.epa.gov/air/tribal/tribalnsr.html

. 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 of the seven pollutant s listed in the table below ? The emissions from your facility ma y be calculated using the PTE calculator provided at http://www.epa.gov/air/tribal/tribalnsr.html . Be sure to include all new, modified, and existing emission units when determining PTE

.

Yes No

3. Will the fugitive emissions from storage piles and roadways be controlled with wetting, dust supp ressants, sweeping or other appropriate means ?

Yes No

- emergency stationary engines use diesel or biodiesel and have a combined horsepower rating less

than 750 horsepower ? Do not include nonroad mobile engines.

Yes No N/A

- Do not use non

- emergency stationary engines

5. If using metal degreasers, d oes your f acility use cold cleaning as your method of degreasing?

Yes No N/A

- Do not use metal degrease rs

6. Will the facility be located not less than 150 feet from the nearest property boundary and not less than 1,000

feet from the nearest residence ?

Yes NoQuestionnaire: Concrete Batch Plants Page 5 of 5

Version 1.0 7. Do you intend to satisfy the ESA and NHPA requirements according to the procedures attached to the Request for Coverage under the General Air Quality Permit for New or Modified True Minor Source Concrete Batch

Plants ?

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 General Air Quality Permit for New or Modified True Minor Source Concrete Batch Plants

. If you believe based upon your answers in this questionnaire that your new or modified concrete batch plant qualifies for coverage under the General Air Quality Permit for New or Modified True Minor Source Concrete Batch Plants , please contact your

review ing authority to obtain a permit application.

If you answered ‘No’ to any of these questions, your facility may not qualify for coverage under the General Air Quality Permit for New or Modified True Minor Source Concrete Batch Plants . Please contact your reviewing authority to confirm that your facility will not qualify for a permit
