229 Neb. Admin. Code, ch. 19, § 004
When there is a reason to believe, or upon receipt of a complaint, that a variation does not provide freedom from danger equivalent to the published rule or regulation, the Commissioner, after notice to the owner or user and complainant, after such hearing and investigation as the Commissioner may direct, may continue to reaffirm, suspend, revoke or modify the conditions specified in any variation. No declaration, act or omission of the Commissioner, or of the Chief Inspector, Deputy Inspectors or Special Inspectors, other than a written order authorizing a variation as permitted above, shall be deemed to exempt, either wholly or in part, expressly or implied, any owner or user from full compliance with the terms of any rule or regulation.
