performance of any other activity as defined in this article.

    (b)   As used in this section, "orphan landfill site" means:

          (i)   A landfill where the department determines:

remediation requirements and construct, install, maintain and
operate systems to remedy contamination in accordance with a
remediation work plan prescribed by the director for the orphan
landfill site.

     (d) Revenue to the account shall include any monies which
may be deposited in the account for use in identification,

where the department expends funds to remediate or contain

party shall reimburse the department in an amount equal to two
(2) times the expenditure from the account. The attorney
general shall bring suit to recover the reimbursement amount
required in this subsection where recovery is deemed possible.
