Exceptions to this requirement are listed in WAC 246-290-125.(3) Construction documents submitted for approval by purveyors who are required to have a water system plan will not be considered for approval unless a current, approved water system plan that adequately addresses the project is on file with the department. In the event that a purveyor of an existing system does not have a water system plan, the department may enter into a compliance agreement with the purveyor that grants a time extension to complete the water system plan.(4) Construction documents shall be consistent with the standards identified in Part 3 of this chapter and shall include, at a minimum, the following: (a) Drawings.

The change order must identify who will be responsible for obtaining department approval and how change orders will be reported to the department. Significant means a change in materials used, deviations from original intent of project, or changes made to the physical capacity of the project;(e) Record drawings. Record drawings provided to the purveyor following the completion of the project shall be maintained and available to the department upon request.(5) Purveyors shall submit a construction completion report (department form) to the department within sixty days of completion and before use of distribution-related projects in accordance with WAC 246-290-125(3)(f), or other project approved for construction by the department.

The purveyor shall take any follow-up action, as directed by the department, to determine conformance with applicable state water rights laws.(8) Approval of construction documents shall be in effect for two years unless the department determines a need to withdraw the approval.
