Rule making related to liquefied petroleum gas

The State Fire Marshal hereby amends Chapter 226, "Liquefied Petroleum Gas," Iowa Administrative Code.

Legal Authority for Rule Making

This rule making is adopted under the authority provided in Iowa Code sections 101.1(1), 101.2, 101.4, and 101.5.

State or Federal Law Implemented

This rule making implements, in whole or in part, Iowa Code chapter 101.

Purpose and Summary

The purpose of the amendments to Chapter 226 is to update code requirements and incorporate new industry standards within the industry.

These amendments update the current standards in order to adopt the most recent editions of the National Fuel Gas Code and the Liquefied Petroleum Gas Code that have been developed by the National Fire Protection Association (NFPA). The NFPA standards are designed to mitigate risks and to ensure safe installation of liquefied petroleum gas storage, handling, transportation, and use and to prevent failures, leaks, and tampering that could lead to fires and explosions. The most recent standards reflect industry standards and promote safety. Liquefied petroleum gas is a clean-burning fossil fuel that is primarily produced domestically. It can be adapted for many uses, and its use has increased in popularity in residential, agricultural, and commercial markets in the United States and elsewhere. Domestic and global demand is expected to increase markedly in the next five years. Safety standards are important for any fuels that can create public safety hazards, and adoption of the current national standards reflects the current state of knowledge and experience in the industry.

Public Comment and Changes to Rule Making

Notice of Intended Action for this rule making was published in the Iowa Administrative Bulletin on July 3, 2019, as ARC 4521C. No public comments were received. One change from the Notice has been made to correct an error in subparagraph 226.4(1)"a"(2). The proposed amendment cited the 2018 edition of the NFPA 58 Liquefied Petroleum Gas Code, and it has been revised to cite the 2017 edition instead.

Adoption of Rule Making

This rule making was adopted by the State Fire Marshal on August 7, 2019.

Fiscal Impact

This rule making has no fiscal impact to the State of Iowa.

Jobs Impact

After analysis and review of this rule making, no impact on jobs has been found.

Waivers

Any person who believes that the application of the discretionary provisions of this rule making would result in hardship or injustice to that person may petition the Department for a waiver of the discretionary provisions, if any, pursuant to rule 661—10.222(17A).

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).
