Initial In-Plant Inspection: Once a Manufacturer's
compliance assurance manual and plans have been approved, the inspection agency
shall perform the initial inspection. The initial inspection shall consist of
the inspection agency making a station-by-station thorough evaluation of the
manufacturer's operation to assure that the manufacturer is operating in
accordance with the criteria set forth in the previously approved compliance
assurance manual and plans. In so doing, the inspection agency shall utilize
the in-plant inspection checklist specified in Subsection 004.03.
If the manufacturer during the initial inspection is found to be producing units in accordance with the approved compliance assurance manual and plans, the inspection agency shall notify the manufacturer, in writing, with a copy being forwarded to the Nebraska Public Service Commission.
The notification letter to the manufacturer from the inspection agency shall be signed by an authorized agent of the inspection agency and shall include the following
004.04A1 Name of inspection agency.
004.04A2 Name of inspector(s).
004.04A3 Date(s) inspection was
performed.
