The proposed rule amendment revises the rule to change the time period and restrict database submissions to only those claims that involve sinkholes and catastrophic ground cover collapse that were “closed” and “confirmed” on or after January 25, 2007. These guidelines will prevent the database from becoming burdened by claims that do not provide useful information. The time period for which claims shall be submitted has been changed to harmonize the rule with statute. Additional definitions and changes to related dates have also been made.
