To receive reimbursement from the fund for costs incurred in responding to an unauthorized discharge, a state agency must, within 90 days of the General Land Office's (GLO) declaration of the completion of response actions, submit to the GLO a report of its response activities and an itemization of the response costs it incurred. The GLO will approve reimbursement from the fund for costs of response actions it authorized or for any other reasonable and necessary response costs consistent with state response actions. The GLO may require additional information to support a response costs reimbursement claim under this section.
