Over the course of the next six units, you will be developing a course project. You will complete a single section of the course project in every unit by completing one section of the course project, and then you will add to it with the subsequent work in the following unit. This unit work will be in the form of unit mini projects.
Our course project will be to develop a document titled “A Permit by Rule (PBR) Evaluation for a Painting Operation” and will serve as a simulation of our work as a contract environmental engineer to an industrial organization planning a painting operation within the United States.
You have contracted with an industrial organization to engineer and write a state air Permit by Rule (PBR) evaluation for a painting operation facility. According to the local state laws and U.S. Environmental Protection Agency (EPA) laws, the facility must have an air permit before construction begins. Once the facility is completed, the construction air permit will then become the operational air permit for the facility.
As a result, your client wants the air permit to automatically align the painting operation facility into operational compliance with state and federal air quality laws. Consequently, it is extremely important for you to evaluate the planned painting operation against the PBR requirements in order to meet the air permit criteria, using the state guidance document and considering the equipment and chemicals already planned for the facility operations.
You have tabulated the following information from what you have gleaned from the material SDS documents and equipment technical data sheets plan (depending on your scenario selection, each “unit” represents a single aircraft, rail tank car, or vehicle):
Interior Liner Coating Material
10 gallons coating/unit
2 gallons of solvent/unit
Unit Lining Application
Apply interior liners to two (2) units/day
Work five (5) hours/day and four (4) days/week
Unit Lining Curing
Cure interior liners of two (2) units/day
Work five (5) hours/day and four (4) days/week
Interior Liner Cure
Heater fuel source is natural gas-fired drying oven
Heater generates 2.1 million (MM) Btu/hr at maximum 2,500 hrs/year
Unit Lining Design
Cross-draft air plenum
Unit interior is the spray area
10,000 ft3/min (CFM)
1 exhaust fan
Air Makeup Unit
5760 ft3/min (CFM)
1 air makeup system
20.0 ft2 each
Two (2) filter openings
2.8 lb/gal coating
Per gal/exempt solvent
Exempt solvent volume
Additionally, your state’s department of environmental quality (DEQ) has provided you the following PBR limits:
Potential to Emit (PTE)
100 tons VOC/year
From your first visit with your client, these are your notes and process flow sketch reflecting the intended operational design:
In following units (Units III through VII), the unit lessons will contain information related to the interior surface coating operation by means of practical mathematical calculation examples. Consequently, it is imperative that you read the unit lessons within the study guide in every unit, use the math calculation examples provided in each unit lesson, and consider the current (as well as previous) material from the textbook and the additional information cited and referenced in the study guide for every unit. This project will serve as a comprehensive demonstration of your applied learning of engineering air quality.
Your completed mini project should be a minimum of one page, not counting the title page, abstract page, and reference page. You are required to use at least one outside source, which may be your textbook. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying APA citations.
