appellees. 2

MCDONALD, Justice. The Vagts family owns and operates a dairy farm in West Union, Iowa.

Northern Natural Gas Company (NNG) operates a natural gas pipeline that runs

under the Vagts’ property. NNG uses a cathodic protection system, which runs

an electrical current through the pipeline to prevent the corrosion of the pipeline.

The Vagts alleged that stray voltage from the cathodic protection system

distressed their dairy herd and caused them damages. They filed this nuisance

suit against NNG. The jury returned a verdict awarding the Vagts a total of

$4.75 million in damages. NNG timely filed this appeal. NNG raises two issues

in this appeal. First, whether the district court erred in instructing the jury on

nuisance without including negligence as an element of the claim. Second,

whether the district court erred in denying NNG’s motion for remittitur.

I.

In 1957, Lawrence Vagts and his brother Ewald Vagts purchased a small

twenty- to thirty-cow stanchion barn in West Union to start a dairy. The Vagts

family has continuously operated the dairy since its founding in 1957. Today,

Vagts Dairy, LLC. is managed by Lawrence’s grandson, Mark Vagts, and Mark’s

son, Andrew Vagts. Mark and his wife, Joan, live on a heifer farm about one mile north of the dairy. Andrew, his wife, Stephanie, and their four daughters live at

the homestead on the dairy.

NNG is an interstate natural gas pipeline company that provides natural

gas transmission services to utilities and other end-use customers. NNG’s

pipeline stretches across eleven states from Texas to Michigan and includes

approximately 14,000 miles of pipeline. NNG operates its pipeline pursuant to a

Federal Energy Regulatory Commission certificate of public convenience and

necessity. The Federal Petroleum and Hazardous Materials Safety Administration requires pipeline companies such as NNG to use a cathodic 3

protection system. See 49 C.F.R. § 192.455(a)(2) (2019) (providing that “each

buried or submerged pipeline . . . must have a cathodic protection system”). A

cathodic protection system runs a low-level electrical current through the

pipeline to mitigate corrosion. The system receives electrical current through a

rectifier that converts alternating current (AC) to direct current (DC). The rectifier

connects the pipeline and an anode bed, which consists of a series of anodes

buried in the ground. Electrical current runs through the ground between the

anode bed and the rectifier to complete a circuit.

The relationship between the parties began in 1960 when the Vagts

granted NNG an easement to lay its pipeline through the Vagts’ property. The

following year, the Vagts granted NNG a second easement to install a cathodic

protection system on the Vagts’ property. In 1964, NNG installed both its pipeline

and an anode bed on the Vagts’ property. In 2013, NNG replaced the existing,

depleted anode bed with new anodes. The anode bed remained in the same

location. In 2017, the Vagts substantially increased the size of their dairy

operation. They increased the size of their free stall barn, extending it westward

closer to NNG’s pipeline and cathodic protection system, and they increased the

size of their herd to approximately 500 cows. After 2013, the Vagts began to experience difficulty with their dairy

operation. The cows began to display “bizarre, abnormal behavior.” They kicked

off milking units, got into the manure, stood in the waterers, and drank

abnormally. The cows became increasingly sick. The somatic cell count in the

herd increased. Milk production declined. Milk quality declined. The cows died

at an abnormally high rate. In a typical year, approximately 5% of a dairy herd

might die. In the year 2022, more than 17% of the Vagts’ dairy herd died. All of

this resulted in excess costs, decreased revenue, and lost profits for the dairy as well as great stress and anxiety for the Vagts. 4

The Vagts engaged a number of people to diagnose and remedy the

situation. They consulted with farm operators, nutritionists, veterinarians, and

equipment manufacturers. None could explain the bizarre behaviors, sickness,

and death. After exhausting other possibilities, the Vagts decided to test their

farm for stray voltage, which can be “catastrophic to a dairy farm.” Schlader v.

Interstate Power Co., 591 N.W.2d 10, 12 (Iowa 1999) (quoting Larson v. Williams

Elec. Co-op., Inc., 534 N.W.2d 1, 1 n.1 (N.D. 1995)). The Vagts hired Lawrence

Neubauer to test for stray voltage on their farm. Neubauer detected electrical

currents in the ground, primarily DC current.

The Vagts subsequently contacted the Allamakee–Clayton Electric

Cooperative, Inc. (ACEC) regarding the stray voltage. ACEC tested the site and

reported stray electrical current. ACEC subsequently contacted NNG.

Representatives of NNG visited Vagts Dairy and detected stray voltage. NNG

believed that the detected voltage fell below the level of concern established in

the “Redbook” and the Iowa Stray Voltage Guide. The Redbook is published by

the United States Department of Agriculture and is cited by the Iowa Stray

Voltage Guide. Nonetheless, in late October 2020, NNG shut down the rectifier

nearest to the Vagts’ free-stall barn. However, NNG added anode beds to the cathodic protection system and increased the electrical energy applied to each of

the anode beds.

In March 2021, the Vagts filed this suit against NNG and ACEC. Counts 1

and 2 asserted claims of nuisance and negligence, respectively, against NNG.

Count 3 asserted a claim of negligence against ACEC. Count 4 asserted a claim

of abatement against NNG and ACEC. In October 2022, the Vagts dismissed their

negligence action against NNG. Soon after, in November 2022, the Vagts

dismissed with prejudice their negligence action against ACEC. 5

The matter came on for trial in January 2023. The Vagts submitted

proposed jury instructions to the district court. The Vagts proposed marshaling

instruction for its nuisance claim provided that:
