Adopted and Filed
Rule making related to a statewide standard for permitting certain implements of husbandry
The Department of Transportation hereby amends Chapter 181, "Statewide Standard for Permitting Certain Implements of Husbandry," Iowa Administrative Code.
Legal Authority for Rule Making
This rule making is adopted under the authority provided in Iowa Code sections 307.12 and 321.463(4).
State or Federal Law Implemented
This rule making implements, in whole or in part, Iowa Code section 321.463(4) as amended by 2019 Iowa Acts, Senate File 555, section 1.
Purpose and Summary
This rule making implements the change made to Iowa Code section 321.463(4) within 2019 Iowa Acts, Senate File 555, section 1. The amendment allows a local authority to issue a special permit letting a self-propelled implement of husbandry used exclusively for the application of organic or inorganic plant food materials, agricultural limestone or agricultural chemicals to operate over a bridge within the local authority's jurisdiction with a weight in excess of weight limitations established by the local authority but within the weight limitations imposed by Iowa Code chapter 321. Before issuing a special permit, the local authority must evaluate the affected bridge according to the American Association of State Highway and Transportation Officials Manual for Bridge Evaluation. The amendment also makes a correction to the name of the Bridges and Structures Bureau.
Public Comment and Changes to Rule Making
Notice of Intended Action for this rule making was published in the Iowa Administrative Bulletin on July 15, 2020, as ARC 5081C. No public comments were received. No changes from the Notice have been made.
Adoption of Rule Making
This rule making was adopted by the Department on September 8, 2020.
The Department is unable to determine the fiscal impact of allowing a local authority to issue a special permit granting operation over a bridge within its jurisdiction of a self-propelled implement of husbandry used exclusively for the application of organic or inorganic plant food materials, agricultural limestone or agricultural chemicals with excess weight. Special permits cost $35 for single trip and $200 for multitrip. Unladen self-propelled implements of husbandry typically do not exceed legal axle loads. Fully laden self-propelled implements of husbandry are estimated to have axle loads that will not permit them to cross many bridges. It is difficult to estimate how many operators will apply for a special permit to operate these self-propelled implements of husbandry partially laden.
After analysis and review of this rule making, no impact on jobs has been found.
This rule does not provide for waivers because issuance of permits is at the discretion of local authorities.
Review by Administrative Rules Review Committee
The Administrative Rules Review Committee, a bipartisan legislative committee which oversees rule making by executive branch agencies, may, on its own motion or on written request by any individual or group, review this rule making at its regular monthly meeting or at a special meeting. The Committee's meetings are open to the public, and interested persons may be heard as provided in Iowa Code section 17A.8(6).
This rule making will become effective on November 11, 2020.
