Section 1.1: Air Quality Construction Permit General Information 

52) Project Description 

For New Facilities: On a separate sheet(s) of paper, provide a detailed narrative of the proposed construction at the facility. 

This should include all emission units, processes, and pollution control equipment being constructed. The descriptions must be 

complete and particular attention must be given in explaining all stages in the process that may result in a discharge of any air 

pollutant. All obtainable data must be supplied concerning the nature, volume, particle size, weights, chemical composition and 

concentrations of all types of air pollutants that are expected to be emitted by the source. All emission point, emission unit, and 

control equipment identification numbers should be present in this description appropriately. 

For Existing Facilities: On a separate sheet(s) of paper, provide a detailed narrative of the production, operations, processes, 

and emission units that currently exist at the facility. This should include all emission units, processes, and pollution control 

equipment that are currently in operation. The descriptions must be complete and particular attention must be given in 

explaining all stages in the process where there is a discharge of any air pollutant. All obtainable data must be supplied 

concerning the nature, volume, particle size, weights, chemical composition and concentrations of all types of air pollutants that 

are emitted by the source. In addition to existing information, narrative of the proposed construction/modification occurring at 

the source must also be discussed with emphasis on the additions/changes occurring. The same information presented for the 

existing sources should also be provided for the new construction/modification. Ensure that the narrative is clear as to what is 

new, existing, and/or being modified. All emission point, emission unit, and control equipment identification numbers should 

be present in this description appropriately. 

53) Facility Layout Diagram (on-file with NDEQ – see NC2 PSD permit appl.)

On a separate sheet(s) of paper, provide a detailed diagram or site drawing that includes all new and existing buildings, stacks, 

and emission points identified in this application. Make sure all elements of the drawing are properly identified, drawn to scale, 

and are consistent with other sections of this application. The plant diagram should indicate the height and location of all 

buildings/structures and property boundaries. Fences or other public access restrictions should be identified and described. 

Clearly indicate which elements currently exist and which will be built/installed/modified. (See Sample Plant Layout Diagram

for an example)

54) Process Flow Diagram

On a separate sheet(s) of paper, provide a flow chart that includes all processes, process equipment, stacks, air pollution control 

equipment, and fuel burning equipment identified in this application. When finished, this diagram should show how products 

and materials (including fuel) flow through each process. Make sure all units are identified and properly cross-referenced to 

match other Sections of the application (including existing units). Provide an inclusive date from which the diagram is valid. 

Clearly indicate which elements exist and which are new. (See Sample Process Flow Diagram for an example of this document)

55) Air Dispersion Modeling Information

Modeling Guidance for determining whether air dispersion modeling may be required can be found on the NDEQ website, or 

contact the Department for assistance. 

Has an air dispersion modeling protocol been established for this source and reviewed by NDEQ? Yes No 

Air dispersion modeling and modeling checklist submitted with application? Yes No 

Note: If air dispersion modeling is required but not included with this application, please provide complete modeling submittal 

and modeling checklist within 30 days to avoid delays in processing this permit application. A delay in submitting the 

modeling can result in the application being placed on hold and the Department cannot guarantee work will resume 

immediately upon receipt of modeling. One original and two copies of the modeling submittal are required.

Section 1.2: Prevention of Significant Deterioration Information 

Answer the following questions if the Source is Subject to the PSD Program. 

Plant-wide Applicability Limits 

1) Are you interested in obtaining a Plant-wide Applicability Limit, also known as a PAL? YES NO 

 If YES, contact the Department in order to discuss the necessary information needed to establish the PAL(s). 

Best Available Control Technology 

2) Select the NSR regulated pollutants for which the potential to emit (PTE) of the entire source (if a new major 

source) or the modification is significant (significance threshold is in parenthesis). 

 Particulate Matter, PM (25 tpy) Sulfuric Acid Mist, H2SO4 (7 tpy) 

 PM with aerodynamic diameter equal to Municipal Solid Waste Landfill Emissions, 

 or less than 10 micrometers, PM10 (15 tpy) Non-Methane Organic Compounds (50 tpy) 

 Nitrogen dioxide, NO2 (40 tpy) Total Reduced Sulfur Compounds, TRS (10 tpy) 

 Sulfur dioxide, SO2 (40 tpy) Hydrogen Sulfide, H2S (10 tpy) 

 Carbon monoxide, CO (100 tpy) Municipal Waste Combustor Acid Gases (40 tpy) 

 Volatile Organic Compounds, VOC (40 tpy) MWC Metals (15 tpy) 

 Elemental Lead, Pb (0.6 tpy) MWC Organics (3.5 x 10-6 tpy) 

 Fluorides (3 tpy) Ozone Depleting Substances, ODS (Any increase) 

 Other: 

Note: If this is a new major source, the threshold for significance is 250 tons/year for each pollutant, unless the source is 

classified as one of the sources listed in Title 129, Chapter 2, Section 002, then the significance threshold is 100 tons/year for 

each pollutant including fugitive emissions. 

For each of the pollutants selected above, a BACT analysis must be conducted for each emission unit that is emitting 

each pollutant (for new sources) or for each unit at which a net emissions in increase of that pollutant would occur as a 

result of a physical change or change in method of operation in the unit (for modifications). A BACT analysis must be 

submitted to the Department as an attachment to this permit application. Contact the Department if help is needed 

determining the information that should be submitted for the BACT analysis. 

 Best Available Control Technology Analysis and Determination for each pollutant selected above is attached. 

OPPD requests an identical CO permit limit and permit conditions as in the PSD permit for the GGS Unit 1 

boiler Low-NOx burner retrofit, issued by NDEQ in late 2006. Attached is a copy of the Permit for that 

permitting action. Because NC1 is nearly identical in size and uses the same fuel as GGS1, the BACT analysis 

for GGS1 is directly applicable to NC1, and has been supplemented based on more recent information.
