  1. EMISSION INVENTORY CASE STUDYPRESENTED BY KRIS RAY Confederated Tribes of the Colville Reservation

  2. LOCATION

  3. COLVILLE RESERVATION MAP

  4. BANDS • Lakes • Colville • San Poil • Nespelem • Southern Okanogan • Moses/Columbia • Palus • Nez Perce • Methow, Chelan • Entiat • Wenatchi

  5. RESERVATION INFORMATION • 7,587 residents • 3.5 people per square mile • Okanogan County - 7.6 people / sq. mile • Ferry County - 3.4 people / sq mile • Major employers - tribal, county, state and federal governments, retail, forest industries, agriculture • Lands in both fee (20%) and trust (80%) status

  6. HISTORY OF EI EFFORTS • Colville Confederated Tribes Emissions Inventory Process Report, August 2001 • Plan for Development of Annual Emissions Inventory System, November 2003 • Point Source Emissions Inventory for the Confederated Tribes of the Colville Reservation - prepared for Western Governors' Association and Western Regional Air Partnership (WRAP), 2006 • Air Emissions Inventory Criteria Pollutants, Base Year 2008

  7. USES OF EI DATA • Monitor sources for changes • Follow trends over time • Effects result from new sources or facility shutdowns • Provides information for potential inspections • Development of a TIP • Region 10 goals • NEI submission

  8. PHASED APPROACH • Phase I – Base line using existing data • FARR registration • Phase II – Nonpoint sources added • Roads • Wildfires • Prescribed burning • Phase III – Off Reservation sources • Parts of five counties • Identify sources that may affect reservation

  9. DATA QUALITY OBJECTIVES • What are the major sources of air pollution and associated emissions levels within the exterior boundaries of the reservation? • What appropriate reduction strategies can be developed and implemented to address the sources?

  10. QUALITY ASSURANCE / QUALITY CONTROL • System of review • Audit procedures • QC - Reality check consisting or completeness and reasonableness reviews. • QA - Peer review

  11. COMPLETENESS CHECKS • Four levels in the TEISS program • Point Location • Facility • Release Points • Emission Units

  12. COMPLETENESS CHECKS • Input tree and printed reports used to verify that all data points needed are satisfied • Assured that units, equipment types, IDs, and other parameters are consistent • If data points are not fully defined, an effort was made to provide necessary information by using source documents • Review of transcription of data to the TEISS program was used to check for accuracy

  13. Reasonableness checks • Determine if data, emission factors and emissions estimates are within range of normal • Compared similar facilities • Compared with surrounding county and state EI information

  14. DATA COLLECTION • Title V permits and reporting documents • Title V fee calculation worksheets and facility applications • Non Title V permits • FARR Registration • Full Compliance Evaluation Technical Report

  15. DATA MANAGEMENT • TEISS data entry • Files stored at multiple locations • Two servers • Two Computer • CD • EPA • ITEP • NEI submittal by ITEP

  16. REPORT DISCUSSION • Criteria Pollutants • Types of Emission Sources • Sources of Emissions • Emission Factors • Inventory Completeness

  17. EI RESULTS

  18. CONCLUSION • QAPP or IPP Important • State the EI strategy • Present results simply • Write for your audience • Look forward to the next EI
