  1. Preparation of an Emissions Inventory for Citizen Potawatomi Nation: Writing a QAPP andStarting a Project Cody BraunEnvironmental Coordinator

  2. EI ?!?!

  3. Tribal area and program background 576,000 acres, approx. 900 sq. miles 27,000 members nationwide 11,000 members within TSJA 5% urban, 7% forest, 9% cropland, 30% pastureland, 44% rangeland Primary land use activity is farming: livestock & agriculture Environmental Department:GAP grant, recycling program, CWA Section 106 grant, CAA Section 103 grant

  4. Emissions Inventory Development and Timeline

  5. QAPP Development / Organization • Format • EPA QA/R-5: Guidance for Quality Assurance Project Plans • Other Tribal examples (ITEP: resources webpage) • Organization/Elements: • Project Management 1-4. Title & Approval Sheet, Table of Contents, Distribution List, Project/Task Organization 5. Problem Definition / Background 6. Project / Task Description (Scope: time frame, geographic area, sources, pollutants) 7. Quality Objectives and Criteria (Level of Complexity) 8. Special Training / Certifications 9. Documentation and Records B. Data Generation and Acquisition 1. Data Collection 2. Emissions Calculations 3. Quality Control and Quality Assurance Activities C.Assessment and Oversight

  6. EI Level/Complexity • Dictated by End use of data • General assessment: establish a fundamental component for developing an air quality control and maintenance strategy • Started with Level 4 – gathered existing NEI/state data • Point sources √ • Found that area source data for counties (OK) were default values, therefore… • Level 3 • Collecting original/site-specific data • Used to guide future planning & research efforts

  7. Quality Objectives and Criteria • Accuracy: thorough documentation, using standardized EPA emission factor methods (AP-42) in TEISS, applying QA/QC checks throughout • Completeness: 100% of point sources, prioritized list of area sources, concerted effort to include as many as possible (activity data limiting), on-road for all highways • Representativeness: calculated emissions will be compared to data from comparable regions/counties • Comparability: results presented in same units as EPA’s CHIEF database

  8. QA/QC Measures • Quality Control – implemented to meet DQO’s; technical • Sound documentation • Data & calculations checking • TEISS & QA/QC checklist • Quality Assurance – more objective assessment of data quality; effectiveness and appropriateness of methods • Peer review: ITEP

  9. Defining the EI Scope • Time frame: 2008 (Jan. 1 – Dec. 31) • Pollutants: CO, NOX, SO2, VOC, PM, Pb, NH3, HAPs from point sources • Geographic Area/Sources: • Point sources within geographical area • 100+ tpy of any criteria, 10 tpy single HAP or 25 combined HAP • Point sources outside jurisdiction to be summarized in separate section of final report • area & on-road mobile within jurisdiction

  10. Something to consider… Wind Rose Sources Lakes Environmental: WRPLOT-View US EPA: WRPLOT State Weather/Climate Offices Meteorological conditions

  11. Point source Geographic Area Shape file… Import into TEISS

  12. Which Area Sources you say? • Accessing NEI Directly (2005, 2008) • Microsoft Access files • Query to narrow your search (state, county, pollutant) • Upside: more complete - all sources included (fires, oil & gas operations, mobile) • Downside: much more time consuming • Importing NEI data into TEISS • Create graphs & charts by SCC code • Upside: quick, easy to interpret • Downside • May be lacking some sources – missing any of the four SCC codes (fires, oil & gas operations), mobile sources • must re-run the filter to get to specific area source

  13. NEI Access File

  14. Area Sources of Concern

  15. Area Sources of Concern cont. • Residential woodstoves • Residential natural gas combustion • Unpaved roads • Agriculture • Tilling • Livestock • Fertilizer application • Mining and quarrying • Diesel idling

  16. Data/Information Gathered • Check TEISS calculator for activity data needed • Fuel throughput • Chords of wood burned & weight per chord • Number of tilled acres • Miles of paved/unpaved roads & traffic counts • # of homes using natural gas, wood stoves • Natural gas consumption • Acres of land burned • Hours idling??

  17. Data Sources • State Department of Transportation • Google maps • State Fire Marshall (NFIRS) • Energy Information Administration • U.S. Census Data • National Agricultural Statistics Service • State Dept. of Environmental Quality • Site visits • Local knowledge

  18. Example Calculation for activity data • Residential Natural Gas Combustion • Energy Information Admin. • Statewide: Residential consumption = 66,225 MM ft.3 • Statewide: 923,650 homes • Census Bureau • 15, 297 homes in CPN TSA w/ natural gas 66,225 mcf = X mcf 923,650 homes 15,297 homes X = 1,097 mcf This is your activity data ready to input into TEISS

  19. Another example calculation… 8.1 miles AADT = 6,000 vehicles VMT = 8.1 miles X 6,000 vehicles/day X 365 days = 17,739,000 vehicle miles/year

  20. Where to from here? • Finish collecting activity data: Documenting everything!! • Import 2008 NEI Point Source Data • Perform calculations in TEISS (check units) • Maintain good records for QA/QC • Peer review: ITEP • Write and submit final EI report and area source data to NEIS • Baseline established for future air-related activities

  21. Questions? EI!! 
