## CALPUFF Modeling: File Structure and Naming Convent **ion**

**Purpose:** This document outlines the file structure and nami ng convention used for the November 2015 EPA conduc ted for the Utah Regional Haze Federal Implementation P lan.

1. The modeling protocol and other model related docum ents are contained in the home folder titled: Model_Documents 2. CALPUFF model files are located in the folder title d: EPA CALPUFF Modeling (November 2015) - Regional Haze Federal Implementation Plan 3. The CALPUFF executables are contained in the home f older titled: Executables 4. The Ozone files are contained in the home folder ti tled: Ozone 5. CALMET input, output, executable files are not avai lable on the website because of the size. CALMET ou tput files can be made available upon request. 6. Directory Structure (Each model scenario has the sa me structure outlined below):

• Model Scenario (Baseline, LNB/SOFA, LNB/SOFA/SNCR, LNB/SOFA/SCR) i. 2001 Model Year 1. CALPUFF
a. Hunter – Unit 1 (contains input and output files) b. Hunter – Unit 2 (contains input and output files)

c. Hunter – Unit 3 (contains input and output files) d. Huntington – Unit 1 (contains input and output file s)

e. Huntington – Unit 2 (contains input and output file s) 2. POSTUTIL

• Sources will be represented by the letters in paren theses: Hunter (HU); Huntington (HT)

• Units will be represented by the letters in parenth eses: Unit 1 (01); Unit 2 (02); Unit 3 (03)

• Model Scenarios will be represented by the letters in parentheses: Baseline (Alt9_Basecase); LNB/SOFA (Alt10_CC); LNB/SOFA/SNCR (Alt12_SNCR); LNB/SOFA/SC R (Alt11_SCR)

• Model Years will be represented by the numbers in p arentheses: 2001 (2001); 2002 (2002); 2003 (2003)

• Class I Areas will be represented by the letters in parentheses: Arches National Park (ARCH), Black Canyon of the Gunnison National Park (BLACK), Bryce National Park (BRYCE), Canyonlands National Park (CANY), Capitol Reef National Park (CAPR), Flat Top s Wilderness Area (FTTOP), Grand Canyon National Park (GRANDC), Mesa Verde National Park (MESAV), Zio n National Park (ZION)

• CALPUFF Input and Output Sub-Folders: Source Name_U nit

• POSTUTIL Input and Output Sub-Folders: Source Name_ Unit

• CALPOST Input and Output Sub-Folders: Source Name_U nit 8. Please contact Rebecca Matichuk for more informatio n.
