Mesothelioma Lawyer Nebraska: Legal Rights for Sheldon Station Asbestos Exposure

If You Worked at Sheldon Station and Have Been Diagnosed with Mesothelioma or Asbestosis, You May Have Legal Rights — and Time Is Running Out

URGENT: Nebraska’s Asbestos Filing Deadline Is Strict — Act Now

If you are seeking a mesothelioma lawyer in Nebraska or an asbestos attorney in Nebraska following work at Sheldon Station near Hallam, read this carefully. Nebraska Public Power District’s Sheldon Station coal-fired power plant employed generations of workers who may have been exposed to asbestos-containing materials during construction, maintenance outages, and daily operations. If you or a family member received a mesothelioma or asbestosis diagnosis tied to that work, Nebraska law gives you a defined window to file — and that window closes.

Under Nebraska law, you have four years from the date of diagnosis to file a personal injury lawsuit — Neb. Rev. Stat. § 25-224. Wrongful-death claims run on a separate clock from the date of death under the same statute. Unfortunately, many of the coworkers who shared shifts with you in the earlier years of your career may no longer be reachable. Employment records from that era are often scattered across multiple employers and contractors. Medical documentation from decades ago takes time to locate and authenticate. Every week you wait narrows your options.

This page covers Sheldon Station’s documented construction history, which trades faced the greatest potential for asbestos exposure in Nebraska power plant settings, the diseases that result from asbestos fiber inhalation, and how Nebraska law supports your right to compensation through civil lawsuit and trust fund claims — pursued simultaneously.

Facility History and Overview

About Sheldon Station

Sheldon Station — formally the Nebraska Public Power District (NPPD) Sheldon Energy Center — is a coal-fired power generating station in Lancaster County, Nebraska, near Hallam along the Salt Creek watershed. The plant has served as baseload generation for NPPD’s distribution network for decades, burning Powder River Basin coal.

Construction Timeline and Equipment

The plant was built in two phases:

  • Unit 1 came online in 1961 with a Foster Wheeler boiler, generating approximately 119 megawatts
  • Unit 2 was commissioned in 1964 with a Foster Wheeler boiler, bringing total capacity to approximately 225 megawatts

(Per North American Powerhouse Database)

Both units were installed during the era of near-universal asbestos use in power generation. Boiler construction and maintenance in mid-century coal plants routinely called for thermal insulation, refractory lining, and gasket materials — and throughout this period, those materials contained asbestos as a matter of standard specification.

The Workforce

Sheldon Station employed rotating generations of workers across its construction, operations, and maintenance phases: operators, maintenance crews, contract insulators, pipefitters, boilermakers, electricians, millwrights, and general laborers. Workers across all of these classifications may have been exposed to asbestos-containing materials during construction, routine maintenance, and periodic overhaul outages spanning the 1960s through at least the 1980s.

Why Power Plants Used Asbestos-Containing Materials

The Engineering Reality

Steam-cycle power plants run at extreme heat and pressure. Turbines, boilers, steam headers, and feedwater systems routinely operate at temperatures exceeding 1,000°F and pressures above 2,000 pounds per square inch. Before the Environmental Protection Agency’s 1973 ban on spray asbestos applications and subsequent regulatory tightening, asbestos-containing materials were the engineering standard for managing those conditions. Plant designers, engineers, and specification writers called for them by default — not by exception.

Where ACM Appeared in Coal-Fired Power Plants

Asbestos-containing materials appeared throughout power plant systems:

  • Thermal insulation on pipes, valves, and fittings — sectional, blanket, and pipe-cover forms
  • Refractory materials lining boilers and furnace chambers
  • Gasket and packing materials in flanged connections and valve stems
  • Insulating cement applied to irregular surfaces and joint sealing
  • Block insulation on steam headers and turbine casings
  • Spray fireproofing on structural steel in the powerhouse
  • Floor tiles and ceiling materials in control buildings and auxiliary structures
  • Electrical insulation in cables, arc-chutes, and panel components

The Industry Standard When Sheldon Station Was Built

From the 1940s through the late 1970s, asbestos-containing materials were standard specification in coal-fired power plant construction and maintenance across the United States. Sheldon Station, built in 1961 and expanded in 1964, sits squarely in that window. Asbestos-containing thermal insulation, refractory, and gaskets were not exceptions at plants like this — they were the rule, written into engineering specifications before the first shovel broke ground.

Asbestos-Containing Materials Allegedly Present at Sheldon Station

Based on the facility’s construction era, equipment classification, and documented industry practices at comparable coal-fired power stations, workers and contractors have alleged the presence of asbestos-containing materials throughout Sheldon Station’s systems and structures.

Foster Wheeler Boiler Systems — Units 1 and 2

The Foster Wheeler boilers at Unit 1 (online 1961) and Unit 2 (online 1964) are reported to have been insulated and sealed with:

  • Block insulation allegedly containing asbestos
  • Insulating cement allegedly containing asbestos, applied to seams, penetrations, and joints
  • Refractory materials in boiler casings, economizers, superheaters, and reheaters
  • Pipe covering allegedly containing asbestos on internal and external piping

These materials are alleged to have been applied during original construction and reapplied during maintenance outages over the plant’s operational life. Removing deteriorated insulation and refractory during maintenance cycles is alleged to have generated airborne fiber concentrations in confined boiler workspaces — some of the most hazardous conditions documented in the occupational health literature on this industry.

Steam Piping and Distribution Systems

Miles of steam piping ran through Sheldon Station’s powerhouse and auxiliary buildings, operating at temperatures exceeding 600°F and pressures above 2,000 psi. Workers have alleged this piping system was covered with:

  • Pipe covering — sectional magnesia or calcium silicate insulation with asbestos binders
  • Canvas jacketing reportedly containing asbestos over sectional insulation
  • Gaskets allegedly containing asbestos at every flanged connection
  • Insulating cement allegedly containing asbestos at irregular surfaces and transitions

Turbine Systems and Steam Extraction Equipment

Steam turbines, valve bodies, throttle and extraction valve assemblies, and auxiliary piping may have been insulated with block insulation, blanket insulation, and refractory materials — all allegedly containing asbestos. Cutting, fitting, and removing these materials during each maintenance cycle is alleged to have generated substantial dust-phase fiber concentrations, a finding documented across occupational health literature covering power generation trades.

Valve and Pump Packing

Hundreds of valves, pumps, and rotating equipment throughout Sheldon Station are alleged to have used rope packing, braided packing, and gasket rings — all reportedly containing asbestos — in valve stems, pump shafts, and pump casings. Repacking these components is alleged to have been a regular maintenance task performed throughout the plant’s operational decades by pipefitters, boilermakers, and millwrights, generating asbestos-containing dust each time the work was performed.

Control Building and Auxiliary Structures

Support structures — including the control room, switchgear buildings, and maintenance facilities — were reportedly constructed with floor tiles, ceiling tiles, suspended ceiling systems, and spray fireproofing applied to structural steel, all allegedly containing asbestos. Spray-applied fireproofing on structural steel was routine specification in early 1960s industrial construction.

Electrical Systems

Electrical components from this era are alleged to have contained asbestos, including arc-chutes and blow-out elements in electrical disconnects and contactors, insulation on high-voltage cables, panel board materials, heat-resistant components in control circuits, and thermal barriers in high-amperage electrical equipment.

High-Risk Occupations: Documented Asbestos Exposure Potential at Power Plants

Asbestos-related disease is an occupational illness. At coal-fired power plants like Sheldon Station, specific trades faced the greatest potential for repeated, sustained exposure to asbestos-containing materials. The occupations below are recognized in epidemiological literature as carrying elevated risk in power plant settings — particularly during maintenance and overhaul work.

Insulators

Insulators — particularly members of Heat and Frost Insulators Local 39, covering all of Nebraska — faced some of the highest cumulative exposures documented at facilities like Sheldon Station. Their work allegedly included:

  • Cutting, fitting, taping, and applying asbestos-containing pipe covering and block insulation to active systems
  • Removing old, deteriorated asbestos-containing insulation before applying replacement material — a task alleged to have released high concentrations of airborne fibers
  • Wrapping pipe, equipment, and ductwork with asbestos-containing canvas jacketing
  • Applying asbestos-containing insulating cement to seams, penetrations, and irregular surfaces

Insulators at Sheldon Station are reported to have performed this work during each scheduled maintenance outage — often in unventilated or poorly ventilated boiler casings and confined spaces over periods of weeks.

Pipefitters and Steamfitters

Members of UA Pipefitters Local 464 Omaha worked throughout Sheldon Station’s extensive steam systems and are alleged to have encountered asbestos-containing materials during:

  • Opening flanged joints in high-pressure, high-temperature systems and replacing asbestos-containing gasket materials
  • Repacking valves with asbestos-containing packing — a recurring task as seals degraded under operating conditions
  • Working alongside insulators and boilermakers during scheduled maintenance outages
  • System modifications and repairs requiring disturbance of existing insulation

A power plant the size of Sheldon Station contained hundreds of flanged connection points. Gasket replacement and valve repacking are alleged to have been constant activities throughout the plant’s operational decades.

Boilermakers

Members of Boilermakers Local 11 built and maintained the Foster Wheeler boilers at Units 1 and 2. That work allegedly included:

  • Working inside boiler fireboxes and confined spaces lined with asbestos-containing refractory materials
  • Installing and removing boiler insulation and seal systems
  • Cutting and handling deteriorated refractory materials during outage work

Workers who spent time inside boiler casings during maintenance are alleged to have faced fiber concentrations well above levels recognized today as safe.

Electricians

Electricians, including members of IBEW Local 22 Omaha and IBEW Local 265 Lincoln, are alleged to have encountered asbestos-containing materials in:

  • Insulation on high-voltage cables and control wiring
  • Arc-chutes, heat-resistant components, and insulators in electrical equipment
  • Spray-applied fireproofing on structural steel — overhead work during construction and modification projects
  • Electrical interconnects in boiler control systems where asbestos-containing materials were standard specification

Millwrights and Maintenance Mechanics

These trades are alleged to have performed recurring maintenance on pumps, turbines, fans, and rotating equipment, with potential contact with asbestos-containing gaskets, packing materials, thermal insulation, and lagging and sealing materials during equipment rebuilds.

Control Room and Outside Operators

Plant operators worked in environments where asbestos-containing materials may have been routinely disturbed by nearby tradespeople during both scheduled and emergency maintenance. Operators performing daily rounds through the powerhouse were in proximity to insulation, gasket work, and refractory disturbance — conditions alleged to have created bystander fiber exposure throughout normal plant operations.

Laborers and General Workers

General laborers — responsible for cleanup, debris removal, and material handling during maintenance outages — are alleged to have handled and swept asbestos-containing debris as a routine part of their duties. Dry sweeping of asbestos-containing waste materials is documented in occupational literature as generating some of the highest short-term fiber concentrations in industrial worksites.
