The DNR has updated the pre-processed meteorological data for AERMOD, the default background concentrations, and various guidance documents. Projects with approved protocols that include approval to use the old data, and modeling analyses submitted prior to December 4, 2015, will not have to use the new data. Applicants submitting new projects on or after December 4 should begin using the updated data and guidance immediately. The updates are summarized below.
