1.13 Permit shield. This permit contains conditions and requirements applicable to GCC 

Dacotah, including conditions and requirements applicable to the identified individual emissions 

units. These conditions and requirements are identified in this permit [and generally are 

referenced in Table #2.] Certain regulations, conditions and requirements have been determined 

by the Secretary to be not applicable to GCC Dacotah; these are identified in this permit [and 

generally referenced in Table #2]. Some emission units have no applicable conditions or 

requirements and are noted by their omission from this Permit [and Table #2], which constitutes 

an affirmative decision that no applicable conditions or requirements exist for those emission 

units. [In all cases, any conflict between Table #2 and the requirements and conditions of this 

permit shall be resolved in favor of the language contained in the permit and against Table #2.] 

Compliance with the conditions of this permit shall be deemed to be compliance with any 

applicable requirements of the South Dakota Air Pollution Control Act (SDCL ch. 34A-1) and 

the regulations promulgated thereunder (ARSD art. 74:36) which existed as of the date of permit 

Issued December 2005 12 
issuance and are identified in this permit [and in Table #2], except that this permit shield: 

(a) shall not be applicable if the permit is based upon inaccurate, misleading, or incomplete 

information, or upon mistakes or errors (including typographical), submitted by GCC Dacotah in 

it’s application for a Title V air quality permit; or (b) may not be used as a defense if the owner 

or operator fails to comply with any of the conditions of the permit. 

 

This permit shield shall not alter or affect the following: 

1. The provisions of sections 112(r)(9) and 303 of the Clean Air Act (emergency orders), 

including the authority of the administrator under those sections; 

2. The liability of an owner or operator of a source for any violation of applicable requirements 

prior to or at the time of permit issuance; 

3. The applicable requirements of the acid rain program, consistent with section 408(a) of the 

Clean Air Act; or 

4. The ability of the Secretary or the administrator to obtain information from the facility 

pursuant to section 114 of the Clean Air Act. 

1.14 Credible evidence. In accordance with ARSD 74:36:13:07, credible evidence may be 

used for the purpose of establishing whether the owner or operator has violated or is violation of 

this permit. Credible evidence is as follows: 

1. Information from the use of the following methods is presumptively credible evidence of 

whether a violation has occurred at the source: 

a. A monitoring method approved for the source pursuant to 40 CFR § 70.6(a)(3) and 

incorporated in this permit; 

b. Compliance methods specified in an applicable plan; 

2. The following testing, monitoring, or information gathering methods are presumptively 

credible testing, monitoring, or information-gathering methods: 

a. Any monitoring or testing methods approved in this permit, including those in 40 CFR 

Parts 51, 60, 61, and 75; or 

b. Other testing, monitoring, or information-gathering methods that produce information 

comparable to that produced by any method in section (1) or (2)(a). 

2.0 PERMIT FEES

2.1 Annual air fee required. In accordance with ARSD 74:36:05:06.01, the owner or 

operator shall submit an annual administrative fee and an annual fee. The fee is based on actual 

emissions in accordance with ARSD 74:37. 

2.2 Annual operational report. In accordance with ARSD 74:37:01:06, the Secretary will 

supply the owner or operator with an annual operational report in January of each year. The 

owner or operator shall complete and submit the operational report to the Secretary by March 1 

of each year. The responsible official shall sign the operational report in the presence of a notary 

public. 

Issued December 2005 13 
2.3 Annual air fee. In accordance with ARSD 74:37:01:08, the Secretary will notify the 

owner or operator of the required annual air emission fee and administrative fee by June 1 of 

each year. The fees shall accrue on July 1 and are payable to the Department of Revenue by July 

31 of each year. 

3.0 PERMIT AMENDMENT AND MODIFICATION CONDITIONS 

3.1 Permit flexibility. In accordance with ARSD 74:36:05:30, the owner or operator shall 

have the flexibility to make changes to the source during the term of this permit. The owner or 

operator shall provide the Secretary written notice at least seven days in advance of the proposed 

change (NOTE: The Secretary will forward a copy of the written notice to EPA). The written 

notice shall include a brief description of the change, the date on which the change is to occur, 

any change in emissions, and the proposed changes to this permit. 

The Secretary will notify the owner or operator whether the change is an administrative permit 

amendment, a minor permit amendment, or a permit modification. A proposed change that is 

considered an administrative permit amendment or a minor permit amendment can be completed 

immediately after the Secretary receives the written notification. The owner or operator must 

comply with both the applicable requirements governing the change and the proposed permit 

terms and conditions until the Secretary takes final action on the proposed change. 

A proposed change that is considered a permit modification can not be constructed until the 

Secretary takes final action on the proposed change. Permit modifications are subject to the 

same procedural requirements, including public comment, as the original permit issuance except 

that the required review shall cover only the proposed changes. 

3.2 Administrative permit amendment. In accordance with ARSD 74:36:05:33, the 

Secretary has 60 days from receipt of a written notice to verify that the proposed change is an 

administrative permit amendment. The Secretary considers a proposed change an administrative 

permit amendment if the proposed change accomplishes one of the following: 

1. Corrects typographical errors; 

2. Changes the name, address, or phone number of any person identified in this permit or 

provides a similar minor administrative change at the source; 

3. Requires more frequent monitoring or reporting by the source; 

4. The ownership or operational control of a source change and the Secretary determines that no 

other change in this permit is necessary. However, the new owner must submit a 

certification of applicant form and a written statement specifying the date for transfer of 

operating permit responsibility, coverage, and liability; or 

5. Any other changes that the Secretary and the administrator of EPA determines to be similar 

to those requirements in this condition. 

3.3 Minor permit amendment. In accordance with ARSD 74:36:05:38, the Secretary has 

90 days from receipt of a written notice or 15 days after the end of EPA's 45-day review period, 

Issued December 2005 14 
whichever is later, to take final action on a minor permit amendment. Final action consists of 

issuing or denying a minor permit amendment or determining that the proposed change is a 

permit modification. The Secretary considers a proposed change to be a minor permit 

amendment if the proposed change: 

1. Does not violate any applicable requirements; 

2. Does not involve significant changes to existing monitoring, reporting, or record keeping 

requirements; 

3. Does not require or change a case-by-case determination of an emission limit or other 

standard, a source-specific determination for temporary sources of ambient impacts, or a 

visibility or increment analysis; or 

4. Does not seek to establish or change a permit term or condition for which the source has 

assumed to avoid an applicable requirement, a federally enforceable emission cap, or an 

alternative emission limit. An alternative emission limit is approved pursuant to regulations 

promulgated under section 112(i)(5) of the federal Clean Air Act. 

3.4 Permit modification. In accordance with ARSD 74:36:05:39, an owner or operator may 

apply for a permit modification. A permit modification is any proposed change that meets the 

definition of a modification in ARSD 74:36:01:10 or is not an administrative amendment or a 

minor permit amendment. Modification is defined as a physical change in or change in the 

operation of a source that results in at least one of the following: 

1. An increases in the amount of an air pollutant emitted by that source or in the emission of an 

air pollutant not previously emitted; 

2. A significant change to existing monitoring, reporting, or record keeping requirements in this 

permit; 

3. The change requires or changes a case-by-case determination of an emission limit or other 

standard, a source-specific determination for temporary sources of ambient impacts, or a 

visibility or increment analysis; or 

4. The change seeks to establish or change a permit term or condition for which there is a 

corresponding underlying applicable requirement that the source has assumed to avoid an 

applicable requirement, a federally enforceable emissions cap assumed to avoid classification 

as a modification under Title I of the Clean Air Act, or an alternative emissions limit 

approved pursuant to regulations promulgated un § 112(i)(5) of the Clean Air Act. 

Permit modifications are subject to the same procedural requirements, including public 

comment, as the original permit issuance except that the required review shall cover only the 

proposed changes. 

3.5 Permit revision. In accordance with ARSD 74:36:05:40, the Secretary may reopen and 

revise this permit to meet requirements of SDCL 34A-1 or the federal Clean Air Act. 

3.6 Testing new fuels or raw materials. In accordance with ARSD 74:36:11:04, an owner 

or operator may request permission to test a new fuel or raw material to determine if it is 

compatible with existing equipment before requesting a permit amendment or modification. A 

complete test proposal shall consist of the following: 

Issued December 2005 15 
1. A written proposal that describes the new fuel or raw material, operating parameters, and 

parameters that will be monitored and any testing associated with air pollutant emissions 

during the test; 

2. An estimate of the type and amount of regulated air pollutant emissions that will result from 

the proposed change; and 

3. The proposed schedule for conducting the test. In most cases the owner or operator will be 

allowed to test for a maximum of one week. A request for a test period longer than one week 

will need additional justification. A test period shall not exceed 180 days. 

The Secretary shall approve, conditionally approve, or deny in writing the test proposal within 

45 days after receiving a complete proposal. Approval conditions may include changing the test 

schedule or pollutant sampling and analysis methods. Pollutant sampling and analysis methods 

may include, but are not limited to performance testing, visible emission evaluation, fuel 

analysis, dispersion modeling, and monitoring of raw material or fuel rates. 

If the Secretary determines that the proposed change will result in an increase in the emission of 

a regulated air pollutant or result in the emission of an additional regulated air pollutant, the 

Secretary shall give public notice of the proposed test for 30 days. The Secretary shall consider 

all comments received during the 30-day public comment period before making a final decision 

on the test.

The Secretary will not approve a test if the test would cause or contribute to a violation of a 

national ambient air quality standard or a prevention of significant deterioration increment. 

4.0 PERMIT RENEWAL REQUIREMENTS 

4.1 Permit effective. In accordance with ARSD 74:36:05:07, this permit shall expire five 

years from date of issuance unless reopened or terminated for cause. 

4.2 Permit renewal. In accordance with ARSD 74:36:05:08, the owner or operator shall 

submit an application for a permit renewal at least 180 days before the date of permit expiration 

if the owner or operator wishes to continue an activity regulated by this permit. The current 

permit shall not expire and shall remain in effect until the Secretary takes final action on the 

timely permit renewal application. 

4.3 Permit expiration. In accordance with ARSD 74:36:05:28, permit expiration terminates 

the owner’s or operator’s right to operate any unit covered by this permit.

particulate limits at the new range. The performance test shall be conducted within 60 

days after the deviation is noted. 

9.0 Best Available Control Measures for Fugitive Dust Sources 

9.1 Unpaved road controls. In accordance with ARSD 74:36:09:02, as referenced to ARSD 

74:36:05:16.01(8), the owner or operator shall apply a chemical stabilizer on all main haul roads 

and a chemical stabilizer or water on all secondary roads that have daily vehicular traffic or an 

alternative method approved by the Secretary. The frequency of applying chemical stabilizer or 

water will be on an as needed basis to comply with the opacity limit in permit condition 9.8. The 

owner or operator may pave the main haul roads or secondary roads with tack seal, asphalt, 

recycled asphalt, or concrete. If the main haul road or secondary haul road is paved, the owner 

or operator shall meet the requirements of permit condition 9.2. A main haul road is defined as a 

passageway between the mining area and the processing facility or between the processing 

facility and the storage area in which material is transferred on a road. A secondary haul road is 

defined as a passageway in which there is daily vehicular traffic on normal working days other 

than the main haul roads. 

9.2 Paved road and parking area controls. In accordance with ARSD 74:36:09:02, as 

referenced to ARSD 74:36:05:16.01(8), the owner or operator shall sweep and water flush, 

vacuum and water flush all paved roads and parking areas, or an alternative method approved by 

the Secretary to remove particulate matter that has the potential to be resuspended. The 

frequency of cleaning will be on an as needed basis to comply with the opacity limit in permit 

condition 9.8.

9.3 Track out area controls. In accordance with ARSD 74:36:05:16.01(8), the owner or 

operator shall pave (asphalt or concrete) a track out area to maintain a stabilized surface starting 

from the point of intersection with the public paved surface into the facility boundary for a total 

distance of at least 100 feet and a width of at least 20 feet or install a wash station and require all 

haul truck vehicles leaving the facility to remove track out materials through the use of water. 

For temporary track out areas (in use for less than 60 days in a calendar year), techniques and/or 

controls shall be implemented so as to prevent particulate matter from becoming entrained in 

violation of the opacity limit in permit condition 9.8. 

9.4 Reclamation plan. In accordance with ARSD 74:36:05:16.01(8), the owner or operator 

shall implement the reclamation plan approved by the Secretary. The owner or operator may 

propose modifications to the approved reclamation plan by written notice to the Secretary. The 

Secretary shall notify the owner or operator within 90 days after receipt of a modification to a 

reclamation plan on if the proposed modification is approved or disapproved. If the proposed 

modification is disapproved, the Secretary will provide the reason why the proposed 

modification was not approved and what is required for the proposed modification to be 

approved. The owner or operator shall resubmit the revised modification within 90 days of 

receiving the Secretary’s notification. Lands which have been reclaimed and approved by the 

Secretary shall no longer be subject to the reclamation plan requirements as long as they remain 

reclaimed. 

9.5 Open storage pile control. In accordance with ARSD 74:36:09:02, as referenced to 

ARSD 74:36:05:16.01(8), the owner or operator shall sample and analyze the silt content of open 

storage piles that have a height greater than or equal to three feet and have a total surface area 

greater than or equal to 150 square feet. The analysis shall be conducted once per calendar year 

and in accordance with ASTM C-136 or another equivalent method approved by the Secretary. 

Open storage pile controls shall be applied to each open storage pile that has a silt content of 

four percent by weight or greater. Silt is defined as any material with a particulate size less than 

74 micrometers in diameter and passes through a number 200 sieve. Open storage pile controls 

shall be applied or constructed in a manner that maintains compliance with the opacity limit in 

permit condition 9.8. Open storage pile controls shall consist of at least one of the following: 

1. Apply chemical stabilizer to the surface area of all open storage piles; 

2. Apply water to the surface area of all open storage piles; 

3. Install at least a two-sided enclosure with walls extending, at a minimum, to the top of the 

open storage pile; or 

4. An alternative method approved by the Secretary 

9.6 Waste pit controls. In accordance with ARSD 74:36:05:16.01(8), the owner or operator 

shall apply a soil cement, water spray, or similar application to create a crusted surface over the 

entire waste pit or implement a combination of wind protection (i.e., wind-fence, wind-screen, 

three wall enclosure, etc.) and water spray application. Waste pit controls shall be applied or 

Issued December 2005 39 
constructed in a manner that maintains compliance with the opacity limit in permit condition 9.8. 

 

9.7 Blasting controls. In accordance with ARSD 74:36:05:16.01(8), no owner or operator 

shall blast during a high wind dust alert that is in effect except if the detonation charges have 

been set in the blasting holes prior to being notified of the high wind dust alert. 

9.8 Opacity limit for fugitive sources. In accordance with ARSD 74:36:09:02, as 

referenced to ARSD 74:36:05:16.01(8), the owner or operator shall not discharge a visible 

emission to the ambient air of a density equal to or greater than 20 percent opacity from an 

unpaved road, paved road or parking lot, crushing operation, open storage pile, track out area, or 

waste pit. The 20 percent opacity reading is based on a series of two minutes averages with a 

minimum observation period of six minutes. The opacity reading shall be determined by 

Tennessee Visual Emissions Method 1 as approved by EPA in 40 CFR §52.2220 or by 40 CFR 

Part 60, Appendix A, Method 9. 

If an operation exceeds the opacity limit, the Secretary will allow the owner or operator two 

opportunities to correct the exceedance with existing controls and/or control measures. In the 

event of a third exceedance from the same operation, the Secretary will notify the owner or 

operator that the Best Available Control Measure (BACM) for that operation must be 

reevaluated. The owner or operator shall reevaluate BACM for that operation and submit a 

written proposal to the Secretary on the proposed new BACM for the operation within 60 days of 

receiving the Secretary’s notification. The Secretary shall approve or disapprove the proposed 

new BACM within 60 days of receiving the proposal from the owner or operator. Once the 

proposed new BACM is approved by the Secretary, the permit will be revised to include the new 

BACM using the appropriate permit revision method identified in Chapter 3.0 of this permit. 

9.9 Opacity readings during a high wind dust alert. In accordance with ARSD 

74:36:09:02, as referenced to ARSD 74:36:05:16.01(8), opacity readings documenting an 

exceedance during a high wind air pollution alert shall not be considered an exceedance of the 

opacity limit in permit condition 9.8. A high wind air pollution alert is based upon the following 

weather conditions: 

1. Winds equal to or greater than 20 miles per hour on an hourly average occurring for two or 

more consecutive hours; 

2. Peak winds of 40 miles per hour (one minute average) or greater; and 

3. The above wind conditions with three or more days of low precipitation (less than 0.02 

inches).
