Development of TRI-NATA Explorer
Goal - Put TRI air emissions into risk context OEI has developed TRI database OAQPS has developed NATA database OAQPS had initially developed NATA-
explorer tool (unfunded!) OEI Staff have begun enhancing the tool

What is NATA?
Characterization of air toxics risks across the nation Modeling assessment performed by the USEPA to characterize
chronic cancer and noncancer risk estimates for the 133 HAPs Includes many sources of outdoor origin Inhalation only
Tools for State/Local/Tribal Agencies (and EPA) to prioritize pollutants, emission sources and locations of interest Provides a starting point for local-scale assessments Focuses on community efforts Informs monitoring programs
Results are available in database on NATA website

NATA History
1996 NATA Based on 1996 NTI Release May 2002 33 HAPs
1999 NATA Based on 1999 NEI Released Feb 2006 177 HAPs
2002 NATA Will be based on 2002 NEI Expected Release Early 2008

Who currently uses NATA? EPA
Data for standard setting Risk and Technology Review Area source rulemaking MSAT Rule used NATA for current and projected risk levels
Air Toxics monitoring NATTS Priority HAPs/Site locations Support Urban monitoring efforts
Accountability Measures GPRA, 112(k), PART AQM Phase 1 ( Recommendation 1.5 Framework for Accountability)
Used to link Air Toxic to Criteria Program Overlay “Hot Spots” with nonattainment areas (e.g. Detroit) Evaluate the toxic components of PM
States Many State Air Toxic Program set air toxic priorities using NATA Identify gaps in emissions inventories and encourages inventory improvements
Communities Serves as a starting point Information and priority setting

Improvements in the 2002 NATA
Inventory Improvements Cr speciation More tribal data RTR review Integration of HAPs and CAPs QA/QC
Improved point source characterization Model at census block using HEM3 (AERMOD) Retain individual source contributions
Will group into source categories
Improved non-point source characterization Area sources - grouped into 27 area source bins Mobile sectors - grouped into 9 source bins
Updated exposure characterization approach Using exposure ratios in lieu of running HAPEM Allows us to retain individual facility and areas source category contribution to risk
Improved Background Characterization Updated monitoring data (NATTS) Improved regional representation

Getting the Right Information
How can TRI-NATA Explorer better provide information community audiences are interested in?
How can we make the risk information presented by TRI-NATA Explorer more understandable and useful?
How can we help people better understand the uncertainty associated with the information provided by TRI-NATA Explorer?
How can TRI-NATA Explorer be made easier to use?
![Page 12: TRI-NATA Explorer 2008 Toxics Release Inventory (TRI) National Training Conference Washington, DC February 12, 2008 Ted Palma - EPA Office of Air Quality.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f275503460f94c3f88d/html5/thumbnails/12.jpg)

Putting Risk Info into Context
Feedback from focus group was that people want to know: What does a cancer risk of 25 in a million
actually mean? Should I be concerned?
Risk ladder is a visual tool that depicts magnitude of risk. Risk in question compared against more
familiar types of risk

Putting Risk Info into Context
OEI and OAQPS considering other possible risk ladders
Examples Risks of daily life: car, plane, bike accidents Other health risks: smoking, dietary habits Risk associated with EPA decisions: residual
drinking water and air risks

Planned Application Enhancements
Replace or add 1999 NATA data with 2002 NATA data
Retool for public consumption by adding explanatory text (i.e., risk ladder)
Standardize the map controls (pan, zoom, identify) to be consistent with today's mapping applications
