[ Filed April 25, 2002, 4:18 p.m. ]

Date of Adoption: April 25, 2002.

Purpose: To bring rules regarding the movement of manufactured homes into compliance with federal rule, specifically tire loading requirements.

Citation of Existing Rules Affected by this Order: Amending WAC 468-38-120 Transport of extra-legal manufactured housing.

Statutory Authority for Adoption: RCW 46.44.090.

Other Authority: RCW 46.44.170.

Under RCW 34.05.350 the agency for good cause finds that immediate adoption, amendment, or repeal of a rule is necessary for the preservation of the public health, safety, or general welfare, and that observing the time requirements of notice and opportunity to comment upon adoption of a permanent rule would be contrary to the public interest; and that state or federal law or federal rule or a federal deadline for state receipt of federal funds requires immediate adoption of a rule.

Reasons for this Finding: Amendments to federal rule 49 C.F.R. 393 have strengthened the safety requirements for moving manufactured housing by eliminating, in most cases, and reducing in the rest, the allowance to overload tire capacity. The amendment does not provide a transition period, it is effective now.

(b) Length - The length of the manufactured housing unit must not exceed seventy-five feet, including tongue.

(c) Width - The width of the manufactured housing unit must not exceed a box (base) width of sixteen feet. The unit may have an eave provided it does not extend beyond either side by:

(i) More than thirty inches for units with box width less than sixteen feet; or

(ii) More than sixteen inches for units with box width of sixteen feet, however, the overall width shall not, under any circumstance, exceed eighteen feet.

(d) Width exemptions - External features, such as doorknobs, window fasteners, eave cap, clearance lights, and load securing devices, that extend no more than two inches on each side of the unit, are exempt from the overall width measurement.
