Wash. Rev. Code § 78.56.120
The department of ecology may, with staff, equipment, and material under its control, or by contract with others, remediate or mitigate any impact of a metals mining and milling operation when it finds that the operator or permit holder has failed to comply with relevant statutes, rules, or permits, and the operator or permit holder has failed to take adequate or timely action to rectify these impacts.
If the department intends to remediate or mitigate such impacts, the department shall issue an order to submit performance security requiring the permit holder or surety to submit to the department the amount of moneys posted pursuant to RCW 78.56.110. If the amount specified in the order to submit performance security is not paid within twenty days after issuance of the notice, the attorney general upon request of the department shall bring an action on behalf of the state in a superior court to recover the amount specified and associated legal fees.
The department may proceed at any time after issuing the order to submit performance security to remediate or mitigate adverse impacts.
The department shall keep a record of all expenses incurred in carrying out any remediation or mitigation activities authorized under this section, including:
The department shall refund to the surety or permit holder all amounts received in excess of the amount of expenses incurred. If the amount received is less than the expenses incurred, the attorney general, upon request of the department of ecology, may bring an action against the permit holder on behalf of the state in the superior court to recover the remaining costs listed in this section.
