Preparation of an Emissions Inventory for Citizen Potawatomi Nation: Writing a QAPP and Starting a Project Cody Braun Environmental Coordinator

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

1. Submit Initial Emissions Source List to EPA R6 Tribal Air Program personnel September 15, Attend Tribal Emissions Inventory Software Solutions (TEISS) training October 19-22, 2010 (Chicago, IL) 3. Develop a Quality Assurance Project Plan (QAPP) on how Emissions Inventory will be conducted and area(s) to be inventoried January Identify sources from Initial Emissions Source List meeting established criteria for point sources and area sources February Collect data for emission sources from established criteria for point sources and area sources June Calculate emissions estimates using TEISS software August Document and report data to National Emissions Inventory System and EPA Region 6 with final report October 2011 Emissions Inventory Development and Timeline

QAPP Development / Organization Format o EPA QA/R-5: Guidance for Quality Assurance Project Plans o Other Tribal examples (ITEP: resources webpage) Organization/Elements: A.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

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

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

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

Defining the EI Scope Time frame: 2008 (Jan. 1 – Dec. 31) Pollutants: CO, NO X, SO 2, VOC, PM, Pb, NH 3, HAPs from point sources Geographic Area/Sources: o 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 o area & on-road mobile within jurisdiction

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

Point source Geographic Area Import into TEISS Shape file…

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

Area Sources of Concern

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

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

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

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

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

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
