| 摘要： | This memo serves as the final deliverable for Task 1 of CRC-A-88, Evaluation of Data Sources for Improving NEI Inputs, presenting ERGs evaluation of potential on-road inputs to improve for Version 2 of the NEI, and work to proceed under Task 2. This final version reflect comments received from the CRC project panel and EPA is response to the March 30th draft memo. The memo presents (1) initial screening of a broad pool of on-road inputs, narrowing to a list of candidates for detailed evaluation, (2) results of this evaluation for final candidates, focusing on viable data sources and methods to update current defaults, and (3) work to proceed under Task 2, based on the CRC panels comments on the draft memo. The focus of A-88 is to provide improved default on-road inputs at the local level for Version 2 of the NEI, and for EPAs broader inventory and air quality efforts. A corollary objective is to identify and evaluate data sources that could be used by modelers at the regional, state and municipal level to improve inventory and air quality modeling. Our conclusions from Task 1 are that promising national data sources exist to make meaningful improvements in the defaults for several on-road inputs. |
