Technical Support System Review Board Meeting March 8, 2007

TSS Goals Provide a single web-based location for: –Access and display of regional haze technical data –Reference location to support individual regional haze plans Document technical methods for regional haze plans

TSS Goals Ongoing tracking and assessment –Emissions reductions –Monitoring data for regional haze and other air quality programs Adapt to and serve future regional technical needs of WRAP members

WRAP Technical Data Information Centers Visibility Information Exchange Web System (VIEWS): VIEWS provides on-line access to monitoring data, research results and special studies related to visibility. Regional Modeling Center: The WRAP’s Regional Modeling Center at the University of California Riverside provides state and tribal agencies with sophisticated modeling of regional haze in the Western United States. Emissions Data Management System: An emission inventory data warehouse for states and tribes. The system provides a consistent, complete and regional approach to emissions data management and tracking. Causes of Haze Assessment: A detailed analysis of ambient monitoring data for regional haze in the WRAP region. The Technical Support System integrates a number of different information resources under one web-based umbrella.

WRAP Data Centers Support the TSS Data Centers Planning/Decision Tool & Summary Data Haze monitoring data Modeling analysis results Emissions data Monitoring analysis results

TSS Overview Interactive tools to support SIP writers’ needs Graphs Tables Maps Incorporates Tribal areas Data tables available for download –Analysts can examine data and reformat graphics as required

TSS training –Webinar session held February 15 th –Next in mid-April –Tribal session week of June 4 th –Workshop: June IMPROVE data updates for 2005 and 2006 Link with other web sites/data nodes: –Fire Emissions Tracking System (FETS) –Emissions Data Management System (EDMS) Ongoing TSS Work

A few words about regional technical efforts beyond 2007…

Technical air quality studies using WRAP data Rocky Mountain National Park Sulfur and Nitrogen Study (RoMANS) – National Park Service and State of Colorado Rural Ozone Impacts from Oil & Gas emissions in the 4 Corners Region – NPS modeling study Rural Ozone Impacts from Oil & Gas in northeast UT/southwest WY – States of Utah and Wyoming Emissions reductions options analysis – 4 Corners AQ Task Force Cumulative Effects WG Pilot Dust Regional Haze SIP for Salt Creek Wilderness – State of New Mexico Nested BART CalPuff modeling using regional modeling data as background – State of North Dakota

WRAP Technical Support History 15+ years of collaboration Analyses of last 5+ years for haze planning provide a broad basis for: Future studies Continued regional analyses at various scales Addressing emerging topics In-kind support and staff participation by members invaluable Nature and content of studies are member-defined WRAP members will face ongoing air management issues Changes to health standards and exposure measures Multiple values of ecosystem and aesthetic protection How can WRAP adapt, or enhance, technical services to meet these needs in the future?

In addition to Regional Haze, WRAP members face a variety of air quality management challenges Some are locally-oriented such as exceeding the 24- hour PM standard along the Wasatch Front or other populated areas –What is the regional contribution to a local problem? Others have been scoped out as sub-regional –4 Corners AQ Task Force, NE UT/SW WY rural ozone, et cetera Also important to continue to analyze and understand the regional response to emissions control and management programs over time –Haze, ozone, acid deposition, mercury, greenhouse gases, et cetera

WRAP has built a useful and robust technical support capability Monitoring data analysis efforts Emissions data at appropriate spatial, temporal, and chemistry scales –Tribal Emissions Inventory Software Solution (TEISS) –Emissions Data Management System (EDMS) –Fire Emissions Tracking System (FETS) Modeling assistance by RMC Visualization and data analysis of regionally consistent data and information in the TSS
