004.04Initial and Monitoring In-Plant Inspection by Inspection Agencies:
004.04AInitial 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.
004.04A4 Name and address of manufacturer.
004.04A5 Statement from the inspection agency stating "A thorough, complete and station-by-station inspection and evaluation of the manufacturer's construction and inspection process was performed in conformance with its approved plans and compliance assurance manual and Nebraska's standards for modular housing units, and the inspection agency is satisfied that the manufacturer can produce modular housing units in conformance with Nebraska standards for modular housing units on an ongoing basis."
004.04A6 Signed and dated by an authorized agent of the inspection agency.
004.04B If the initial inspection reveals deviations from the previously approved compliance assurance manual and plans, the inspection agency shall notify the manufacturer, in writing, of deviations, specifying in detail the observed deviations. A copy of this letter shall be sent to the Nebraska Public Service Commission. Upon notification from the plant that the specified deviations have been corrected, the inspection agency shall again make an initial inspection of the plant following the procedure previously outlined in this section 004.04A.
004.04CMonitoring In-Plant Inspections: Following notification to a manufacturer under Part 004.04A, the inspection agency shall undertake monitoring in-plant inspections at a frequency sufficient to inspect every home that will receive the Nebraska modular housing unit seal and to assure continuing compliance with the manufacturer's compliance assurance program. Additional factors which the inspection agency shall take into consideration in determining frequency of monitoring in-plant inspections are as follows
004.04C1 Production Volume
004.04C2 Design Complexity of Units
004.04C3 The qualifications of the manufacturer's own

in-house compliance control organization.

004.04C4 The experience record of the manufacturer.
004.04D The in-plant inspection agency shall utilize the in-plant inspection check list in Subsection 004.03 to assure that each construction feature (structural, mechanical, plumbing, and electrical) is fully evaluated.
004.05Seal Issuance: Upon satisfactory completion of the initial in-plant inspection and notification letter issued to the manufacturer by the inspection agency, the manufacturer shall act in accordance with the provisions of Section 002.
