Rule making related to recordkeeping and cost allocations in nonutility activities

The Utilities Board hereby amends Chapter 33, "Nonutility Activities—Record Keeping and Cost Allocations," Iowa Administrative Code.

Legal Authority for Rule Making

This rule making is adopted under the authority provided in Iowa Code section 476.2.

State or Federal Law Implemented

This rule making implements, in whole or in part, Iowa Code sections 476.72 and 476.78 to 476.80.

Purpose and Summary

199—Chapter 33 applies to all rate-regulated public utilities and contains regulations regarding public utilities' nonutility services, including provisions that govern the Board's access to a public utility's nonutility service records, the costing methodologies between a public utility's utility and nonutility operations, and the standards for service and asset transfers between a public utility's utility and nonutility operations. As part of a comprehensive review of its administrative rules in accordance with Iowa Code section 17A.7(2), the Board initiated this rule making to identify and update provisions that are outdated, inconsistent, or incompatible with statutes and other rules.

The Board issued an order adopting these amendments on November 21, 2022. The order is available on the Board's electronic filing system under Docket No.RMU-2021-0033.

Public Comment and Changes to Rule Making

Notice of Intended Action for this rule making was published in the Iowa Administrative Bulletin on June 1, 2022, as ARC 6340C. A public hearing was held on June 23, 2022, at 1:30 the Board Hearing Room, 1375 East Court Avenue, Des Moines, Iowa.

Representatives from the Office of the Consumer Advocate (OCA), a division of the Iowa Department of Justice; Interstate Power and Light Company (IPL); MidAmerican Energy Company (MidAmerican); Black Hills/Iowa Gas Utility Company, LLC, doing business as Black Hills Energy (Black Hills); and Iowa-American Water Company (Iowa-American) attended the public hearing. OCA supported all the proposed amendments and requested that the Board include a reference in rule 199—33.2(476) to the National Association of Regulatory Utility Commissioners' Uniform System of Accounts for water utilities. All other commenting parties either supported or took no position on the proposed amendments.

The Board also received written comments from OCA, Black Hills, IPL, MidAmerican, and Iowa-American. Written comments from OCA supported all the proposed amendments and included the same request regarding rule 199—33.2(476) made by OCA during the hearing. All other commenting parties either supported or took no position on the proposed amendments contained in the Notice.

The Board has made one change from the Notice. In the Notice, the Board proposed to replace the "approval" of manuals with the "acceptance" of manuals in subrule 33.5(2). However, one reference to the "approval" of manuals in subrule 33.5(2) was missed. Because no commenting party opposed replacing "approval" with "acceptance," the Board made this additional change.

Adoption of Rule Making

This rule making was adopted by the Board on November 21, 2022.

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.


No waiver provision is included in the proposed amendments because the Board has a general waiver provision in rule 199—1.3(17A,474,476) that provides procedures for requesting a waiver of the rules in Chapter 33.

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 February 1, 2023.
