Unit II Mini Project

profilema2211
Instructions

Mini Projects every week (Units 2-7), as we draft an air permit evaluation throughout this course, using the template I provide below to build the evaluation sections every week. This week we will be learning engineering strategies for engineering outdoor air quality. Further, we will be beginning our air permit evaluation draft. 


Note:

(a) Download and use the active template (type directly into the MSWord document, and save your changes before you submit it for a grade every week for Units 2-7).  

(e) Any required calculations are fully presented and explained within the Study Guide every week. As such, simply read the Study Guide and present any explained calculations mathematically with empirical math within the permit evaluation draft. 

Use the rest of the section of your paper (every week) to present a narrative of the EH&S concerns, using Godish, Davis, and Fu's (2014) book in every section, and to compare the calculations against the regulatory standard provided and explained in the Study Guide. Do not try and explain the calculations, since you will have already presented them.

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):

   

Interior Liner    Coating Material


10 gallons    coating/unit


2 gallons of    solvent/unit

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

  Potential to Emit (PTE) 100 tons VOC/year  Face Velocity 100 ft/min  Filter Velocity 250 ft/min  VOC/5-hour period 6.0 lbs/hr  Short-term Emissions 1.0 lbs/hr  Long-term Emissions 1.0 tons/yr 

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.

Instructions: 

  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.
