What is eNAT?

The electronic Netting Analysis Tool (eNAT) is a Microsoft Excel based spreadsheet developed by the New Jersey Department of Environmental Protection (NJDEP) for the regulated facilities to calculate netting terms for the contemporaneous period and compare the net emission increase of each air contaminant to the significant net emission increase level for that air contaminant set forth in N.J.A.C. 7:27-18.7 Table 3.
