AIR POLLUTION CONTROL 

AIR QUALITY EFFECTS ANALYSIS 

Applicant Information: 

Tecton Products 

15th Avenue and 44th Street NW 

Fargo, North Dakota 

Cass County 

Proposed Project: 

I. Background: 

Tecton Products operates a door and window lineal plant. The door and 

window products are produced by a process called pultrusion, where 

fiberglass reinforcing material is pulled through a resin bath, is saturated 

and enters a heated die where the polyester is cured into a hardened 

lineal shape which is then cut to length by a cut-off saw. 

II. Project Description: 

An application for a Permit to Construct for expansion of a window and 

door lineal plant located at the aforementioned address was filed with the 

department on October 9,1996 by Tecton Products. Parts of the 

application are confidential and can be found in the confidential safe. 

General Data: 

I. New equipment at the facility: 

1. Pultrusion machines, 10 additional, 5 existing. 

2. Two new 7,400 gallon styrene storage tanks, two existing tanks. 

3. 40 cut-off saws and fabrication equipment. 

4. Caterpillar 1500 bhp emergency generator. 

II. Air pollution equipment at the facility: 

1. An existing catalytic oxidizer, with a control efficiency of 95%, for 

the control of volatile organic compounds. The exhaust from the 

catalytic oxidizer will be vented to the outsize air. 

2. Four cartridge filter dust collection systems for the control of 

particulate matter (fiberglass). The exhaust will be vented into the 

building. The collectors are replacing the existing baghouse.

I. 40 CFR Part 60, Subpart VW 

The Standard for volatile organic compounds (VOC) as outlined in 40 CFR 

Part 60, Subpart VW - Standards of Performance for Polymeric Coating of 

Supporting Substrates Facilities is as follows: 

1. Reduce VOC emissions to atmosphere from the coating operation by 

at least 90 percent ("emission reduction" standard); or 

2. Install, operate, and maintain a total enclosure around the coating 

operation and vent the captured VOC emissions from the total 

enclosure to a control device that is at least 95 percent efficient 

(alternative standard). 

3. For the on-site coating mix preparation equipment, vent the VOC 

emissions to a 95 percent efficient control device. 

Tecton products currently has a catalytic oxidizer that is 95 percent efficient; 

therefore, the facility will comply with the standards outlined in Subpart VW.

P.17 

II. Chapter 33-15-16, Restriction of Odorous Air Contaminants 

The Handbook of Environmental Data on Organic Chemicals, Second 

Edition, indicates the odor threshold of styrene is approximately 0.26 mg/m3. 

The facility will have a control device (catalytic oxidizer) for the control of 

VOCs with an efficiency of 95%. Based on air quality dispersion modeling, 

the 1-hour and 8-hour ambient concentration for styrene from the facility is 

expected to be 0.024 mg/m3 and 0.017 mg/fo, respectively. These 

concentrations are below the odor delegability limit. 

III. Chapter 33-15-03, Restriction of Visisble Air Contaminants 

All emission points at the facility are subject to 20% opacity. 

Expected Emissions: 

Expected emissions for styrene were calculated using EPA AP-42, Compilation of 

Air Pollutant Emission Factors, Section 4.12, Polyester Resin Plastics Product 

Fabrication, Table 4.12-2. 

The emission factor outlined in EPA AP-42 incorporates plant production rates to 

calculate the expected emissions. As outlined by Section 33-15-01-16 of the North 

Dakota Air Pollution Control Rules, Tecton has requested that information on 

production feed streams at the facility be treated confidential. The Department has 

accepted this information as confidential; therefore, the actual calculations of the 

expected emissions will not be shown in this analysis. The Department has 

calculated the expected emissions using an EPA AP-42 emission factor of 5.5%. 

The emissions from the #2 (0.5 % Sulfur) fuel oil fired engine, which runs the 

generator, will be calculated using AP-42, Table 3.4-1 &2. Potential emissions 

(tons/yr) for the generator sets will utilize 500 hrs per year. This number comes 

from the EPA memo dated January 25,1995. A limit on the operating hours for the 

generator sets (of 500 hours) should be included in the Permit to Operate.

Stack diameter = 0.66 m 

Exit velocity = 11.58 m/sec 

Exit temperature = 422 °F 

Building height = 7.01 m 

Building length = 86 m 

Building width = 98 m 

Results of the modeling are as follows (see attached output from SCREEN3): 

1-Hour = 0.024 mg/m3 

8-Hour = 0.017 mg/m3 

MAALs 

1-Hour = 4.26 mg/m3 

8-Hour = 2.13 mg/m3 

Conclusions: 

Tecton Products will not be a major source of any regulated air contaminant. VOCs 

will be emitted. As a result of the amount of VOC used and emitted, the plant is 

subject to 40 CFR Part 60, Subpart VW - Standards of Performance for Polymeric 

Coating of Substrates Facilities. Specific emission rates of VOCs were evaluated 

as outlined in the Air Toxics Policy and the North Dakota Air Pollution Control 

Rules. 

The Department has determined from its review of the application that the 

technology proposed to control emissions from the plant, a catalytic oxidizer for 

VOCs and cartridge filters for particulate, is acceptable and the emission rates will 

comply with the emission rate reduction standards specified in 40 CFR Part 60 

Subpart VW, the Air Toxics Policy, and the North Dakota Air Pollution Control 

Rules. 

The Department conducted air quality dispersion modeling of styrene emissions 

form the plant to predict the impact on air quality. Styrene is classified by the State 

of North Dakota as a Group 3 hazardous air pollutant (HAP). Each Group 3 HAP 

is associated with a Maximum Acceptable Ambient Level (MAAL) for 8-hour and 1-

hour averaging periods. A maximum ground-level concentration less than its 

corresponding MAAL requires no further review by the Department. 

Recommendations: 

The Department finds the Permit to Construct application to be complete. In view 

c* 
P.20 

ofthe results of the evaluation, the preliminary determination ofthe Department is 

that a Permit to Construct be granted for construction of the expansion of Tecton 

Products provided it is constructed in accordance with the application and 

applicable regulations.

Dear Gary: 

Enclosed is our Permit to Construct application, along with three additional 

applications for additional permits. Since we didn't have a form for our additional 

VOC storage tank, I've included that information on a separate page. 

Please contact me if you need more information.
