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.

The Scenario:

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):

Additionally, your state’s department of environmental quality (DEQ) has provided you the following PBR limits:

Short-term   Emissions

1.0   lbs/hr


Long-term   Emissions

From your first visit with your client, these are your notes and process flow sketch reflecting the intended operational design:

  • The      client has designed an interior coating spray painting system that allows      the interior of each unit to be coated.
  • The      operations will involve a stripped-down unit being brought into the      facility’s shop.
  • The      shop is a steel building with a finished concrete floor and a paint booth      for each unit.
  • The      unit will be placed in the spray booth.
  • The      booth will be opened at one end of the booth for makeup air.
  • The      exhaust air will flow through an exhaust chamber at the other end of the      unit.
  • For      each unit, once the liner application operations are completed, the forced      curing (drying) operations will immediately commence.

Booth Exhaust Chamber


  1. Closely      read the required reading assignment from the textbook and the unit lesson      within the study guide, and consider reading the suggested reading.
  2. Select      the PBR evaluation document to be for only one of the      following: (a) an aircraft manufacturing exterior coating paint booth, (b)      a rail tank car interior lining process, or (c) a vehicle exterior coating      paint booth. You will continue with this scenario selection for the      remaining six units, to complete the entire document.
  3. Using      APA style (title page, abstract page, body with level 1 headings, and a      reference page) for a research paper, begin drafting a PBR evaluation      document. You will add to this document in every subsequent unit with      another prescribed level 1 heading, building out the entire document one      section at a time.
  4. Make      your Unit II work the first level 1 heading (center, bold) titled “General      Considerations for Operation,” and describe the scenario that is presented      above, while specifically describing the scenario that you selected      (aircraft, tank car, or vehicle). While describing your scenario, you must      include the environmental, health, and safety (EHS) implications of the      work system while pulling from the textbook as well as any other relevant      sources that are presented in the unit lesson in the study guide. In your      description of the EHS implications of the system, be sure to discuss the      natural and anthropomorphic variables causally related to outdoor air      pollution. You are required to describe the scenario in at least 200 words      (minimum). You may find it convenient to summarize the tabulated information      in your General Considerations section of the permit for future reference      throughout the rest of the course, but do not attempt to tabulate the      information in the exact order as what is presented here (to avoid a high      match in SafeAssign).
  5. Also under      the first level 1 heading, present a box and line process flow diagram      (PFD) drawing of the selected scenario. See the drawing on page 375 of the      textbook as an additional example of a PFD if you need assistance      understanding how to draw one; do not draw the same system that is      provided on that page. Do not hand-draw this, but use the “insert” and      “shapes” features within Microsoft Word to construct the PFD. Simple      labeled boxes and lines are adequate for this preliminary work, so it is      not necessary to present specific shapes in your PFD for your selected      scenario.
  6. In      your abstract section (page 2 of the document), write one or two sentences      that reflect your work for this unit. We will be adding one sentence per      unit to reflect our work as we go, with the final abstract length being      about 8 to 10 sentences long.

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.
