History of EI Efforts  Colville Confederated Tribes Emissions Inventory Process Report, August 2001  Plan for the Development of an Annual Emissions Inventory System, November 2003  Point Source Emissions Inventory for the Confederated Tribes of the Colville Reservation—prepared for Western Governors' Association and The Western Regional Air Partnership (WRAP),

Emission Inventory Efforts Emissions Inventory Preparation Plan, 2008 Air Emissions Inventory Criteria Pollutants, Base Year 2008 Updated Inventory Preparation Plan, 2011 Air Emissions Inventory Criteria Pollutants, Base Year

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 2 years to get all sources registered Phase II – Other sources added Roads – nonpoint Wildfires – event Prescribed burning – event Phase III – Off-reservation sources Parts of five counties Identify sources that may affect reservation 9

Quality Assurance / Quality Control System of review Audit procedures QC – Reality check consisting of completeness and reasonableness reviews QA – Peer review 10

Completeness Checks  Levels in TEISS program  Point Location  Facility  Release Points  Emission Units  Processes  Reporting Period  Actual Emissions 11

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, effort was made to provide necessary information by using source documents  Review of transcription of data to TEISS program used to check for accuracy 12

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