Short Term Wins
After a successful scoping phase, the CAER team identified “short term win” projects to move the overall effort of CAER forward in ways that both meet short term needs and support the larger goals and expected outcomes of this project.
In this phase we began the technical implementation of the proposed future state as identified during the implementation planning for the Combined Air Emissions Reporting (CAER) project.
Harmonization of Cross-Program Code Tables, Data Elements
The Harmonization of Cross-Program Codes Tables, Data Elements project compared and harmonized code tables across multiple emissions inventory development programs. As a result of this project, the CAER team learned how we could reduce and eliminate differences of shared code sets to help streamline data sharing for state/local/tribal air agencies, the EPA, and facilities.
National Emission Inventory Data Augmentation Reduction
The NEI Data Augmentation Reduction project worked to reduce NEI augmentation and the associated time that the EPA needs to augment state/local and tribal (SLT) submitted data. A group of SLT air agencies worked with the EPA to define all data criteria which SLT submittals must meet to help minimize and potentially eliminate the need for EPA augmentation.
Source Classification Code (SCC) Web Access
SCC codes describe emissions processes and are a critical part of compiling and sharing air emissions inventories. The SCC Web Access project developed new ways for anyone (EPA, state/local/tribal air agencies, facility, or public) to access the most updated list of SCCs through web services and other mechanisms.
Improvements to WebFIRE
WebFIRE is the EPA’s official repository of emissions factors and compliance source test data. The WebFIRE Enhancements project has allowed users (EPA, other air agencies, facilities, and the public) to search for source test data in WebFIRE using expanded criteria and to download all resulting test data as a single report.
