The Indiana Brownfields Program (“IBP”) has updated forms related to obtaining a Comfort Letter or Site Status Letter for brownfields sites in Indiana. IBP did so in order to emphasize that the trigger for the 180-day update (and the one-year shelf life for Phase I reports) runs from the earliest date upon which required information was collected or site investigation was conducted. Importantly, the 180 days does not run from the date of the report. This fact is significant to prospective purchasers of brownfields sites seeking bona fide prospective purchaser status because if more than 180 days has elapsed from the initial activity related to data collection or site inspection prior to taking title to the property, then an update will be necessary to comply with the AAI rule.
