(u) “Owner or operator” means: (1) Any person with any ownership interest in the facility or who exercises any control over the facility; or (2) In the case of an abandoned facility, any person who had owned, or operated, or exercised control over the facility any time before its abandonment; (3) The term does not include: A. The Tribe or any Tribal instrumentality which acquired ownership or control involuntarily through bankruptcy, tax delinquency, abandonment, or circumstances in which the Tribe or Tribal instrumentality involuntarily acquires title. i. This exclusion does not apply to an instrumentality of the Tribe which is subject to a waiver of sovereign immunity, which has caused or contributed to the release or threatened release of a hazardous substance from the facility; B. A person who, without participating in the management of a facility, holds indicia of ownership primarily to protect the person’s security interest in the facility.

The holder complies with the reporting requirements in the rules adopted under this Chapter; iii. The holder complies with any order issued to the holder by the Department to abate an imminent or substantial endangerment; iv.

Any remedial actions conducted by the holder are in compliance with any preexisting requirements identified by the Department, or, if the Department has not identified such requirements for the facility, the remedial actions are conducted consistent with this Chapter; and vi. The holder does not exacerbate an existing release. C. The exemption in 34-1.03(u)(3)(B) does not apply to holders who cause or contribute to a new release or threatened release or who are otherwise liable under s 34-1.05(a)(2)-(5); provided, however, that a holder shall not lose this 269 Revised Spokane Law & Order Code, 5/14/2013
