Description

Quality Models (Appendix W to 40 CFR Part 51). The guideline reported on the enhancements to be made to its near-field dispersion model – AERMOD – and that CALINE3 would be replaced by AERMOD as the preferred model for refined transportation project analyses beginning in January 2020. After the removal of CALINE it was Federal Highway Administration (FHWA) priority to make sure the AERMOD was able to accurately predict concentrations in the near road environment for transportation purposes. The Environmental Protection Agency and FHWA collaborated on scientific research and evaluation of the RLINE module for integration into AERMOD.
