(2) Annually, until final closure of the facility, submit to the director a report containing the results of the ground water quality assessment program which includes, but is not limited to, the calculated (or measured) rate of migration of hazardous waste or hazardous waste constituents in the ground water during the reporting period. This information must be submitted, on the form provided by the director, no later than March first following each calendar year.
