Nonpoint Inventory Tools for the 2017 NEI (2017 EIC)
EPA is in the process of overhauling most of the tools used in the nonpoint data category for the 2017 NEI so that these tools fit into one of three categories --method improvements and the State/Local/Tribe inventory submitter review process. The tool category types determine the timeframe for draft tool release, submitter review, and finalization.
