Wash. Admin. Code § 480-103-007
A community solar company may contract with or otherwise retain one or more administrators to perform tasks on the company's behalf that are subject to the rules under this chapter. If an administrator engages in conduct that violates any federal, state, or local law or regulation, or any commission order while acting on behalf of the community solar company, the company is subject to commission enforcement actions as if the company itself engaged in that conduct. The community solar company is responsible for maintaining measures designed to prevent and detect an administrator's violation of statutes or rules within the commission's authority to enforce. Upon commission request, a community solar company must make available records regarding the tasks an administrator performs on the company's behalf. Such records must fully enable the commission to audit, investigate, and determine the company's compliance with applicable law.
