Facility Overview and Asbestos-Containing Materials

The Cedar Rapids Starch Processing Facility

The Penford Products starch facility in Cedar Rapids operated for decades as part of the corn wet-milling and industrial starch processing industry — one of Iowa’s oldest manufacturing sectors. The plant operated through multiple corporate ownership structures, previously associated with Penick & Ford before operating under the Penford Products name.

Industrial starch manufacturing requires large-scale boiler systems, extensively insulated piping networks, and heavy process equipment. These are exactly the settings where asbestos-containing materials were most heavily used throughout the twentieth century.

Systems at the Facility That May Have Contained Asbestos-Containing Materials

Workers at the Penford Products facility may have encountered asbestos-containing materials in connection with:

  • Large-capacity industrial boilers generating process steam
  • High-pressure steam distribution networks spanning the facility
  • Heat exchangers and evaporators for thermal management
  • Industrial dryers for final starch processing
  • Extensively insulated piping carrying high-temperature steam throughout the plant
  • Equipment housings and process vessels requiring thermal insulation and fireproofing

Workers who built, maintained, and repaired these systems may have been exposed to asbestos-containing materials across many decades of plant operations.

Why Starch Processing Plants Used Asbestos-Containing Materials

Heat and Steam Requirements in Corn Starch Manufacturing

Industrial starch production runs on sustained high-temperature operations. Raw corn processing requires:

  • High-pressure steam generation via large industrial boilers
  • Steam distribution networks carrying high-temperature, high-pressure steam throughout the facility
  • Evaporators and dryers operating at sustained elevated temperatures
  • Heat exchangers managing thermal energy across multiple process stages
  • Distillation and drying equipment for final product processing

Why Asbestos Was the Industry Standard for Thermal Insulation

From roughly the 1920s through the late 1970s — and in some cases into the 1980s — asbestos-containing materials were the default insulation for industrial systems. Manufacturers including Johns-Manville, Owens-Illinois, Crane Co., and Georgia-Pacific marketed asbestos-containing insulation products based on these properties:

  • Heat resistance — capable of withstanding temperatures that would destroy alternatives
  • Fire resistance — particularly relevant in facilities handling combustible corn dust and processing byproducts
  • Durability — capable of withstanding vibration, pressure cycling, and physical handling common in industrial environments
  • Low cost — products from Johns-Manville and Owens-Illinois were inexpensive and widely available
  • Ease of application — pipe covering, block insulation, and spray-applied products installed quickly

Where Asbestos-Containing Materials Appeared in Industrial Starch Facilities

Facilities like Penford Products may have reportedly contained asbestos-containing materials from major manufacturers in virtually every major system:

  • Boiler insulation — products such as Johns-Manville Kaylo and Thermobestos blocks
  • Pipe covering — pre-formed asbestos-containing pipe insulation sections
  • Valve and flange packing and gaskets
  • Expansion joint materials and thermal breaks
  • Boiler refractory materials and insulating cement
  • Floor tiles and ceiling tiles — potentially including Armstrong World Industries products containing asbestos
  • Roofing materials
  • Electrical insulation — asbestos-wrapped wire and cable

Iowa DNR NESHAP Documentation of Asbestos-Containing Materials at Penford Products

What NESHAP Records Are and Why They Matter

The National Emission Standards for Hazardous Air Pollutants (NESHAP) program, established under the Clean Air Act and administered at the state level by the Iowa Department of Natural Resources (Iowa DNR), requires property owners and operators to notify regulators before demolishing or renovating structures containing regulated asbestos-containing materials.

These NESHAP asbestos notifications create public records identifying:

  • Specific locations where asbestos-containing materials were found
  • Types of materials discovered at the facility
  • Abatement actions undertaken
  • Timeline of removal and remediation activities

What Iowa DNR NESHAP Records Show for Penford Products

Per Iowa DNR NESHAP abatement records, asbestos-containing materials were allegedly identified at the Penford Products starch facility in Cedar Rapids in connection with:

  • Boiler insulation systems — potentially including products from Johns-Manville, Owens-Illinois, and similar manufacturers
  • Pipe insulation networks carrying steam and process fluids
  • Associated thermal systems and equipment throughout the facility

This documentation matters to injured workers and their families for four concrete reasons:

  1. It confirms the presence of regulated asbestos-containing materials through state agency records
  2. It identifies specific locations and system types where asbestos-containing materials were found
  3. It establishes a timeline showing when asbestos-containing materials were still present and potentially friable
  4. It supports compensation claims and civil litigation by placing asbestos-containing materials in the areas where workers performed their jobs

Workers Who May Have Been Exposed Through Boiler and Steam System Work

Workers who performed maintenance, repair, and renovation work on boiler systems, steam lines, and related infrastructure before comprehensive abatement may have been exposed to asbestos-containing materials during the ordinary course of their work duties.

NESHAP abatement records at Iowa industrial boiler facilities have documented asbestos-containing materials in boiler and steam systems — materials that may also have been present at the Penford Products facility:

  • Asbestos-containing pipe covering from manufacturers such as Johns-Manville and Owens-Illinois — pre-formed half-sections applied over steam lines (documented in NESHAP abatement records)
  • Asbestos-containing block insulation — products such as Kaylo and Thermobestos applied over boiler surfaces, ductwork, and equipment
  • Asbestos-containing insulating cement — trowel-applied to fittings, flanges, and irregular surfaces
  • Asbestos boiler rope and gaskets — used at inspection ports, manholes, and access doors
  • Asbestos-containing refractory materials — furnace linings and combustion chamber insulation
  • Spray-applied asbestos fireproofing — reportedly used on structural steel in industrial buildings of this era, potentially including products such as Monokote from W.R. Grace or Aircell
  • Asbestos-containing floor tiles and mastic — 9×9 and 12×12 vinyl asbestos tiles common in industrial settings through the 1980s, potentially including Gold Bond products
  • Asbestos-containing roofing materials — potentially from manufacturers such as Celotex, Georgia-Pacific, or Pabco

Who Was Exposed: High-Risk Trades and Job Classifications

Asbestos exposure in industrial settings is an occupational disease — workers in specific trades faced elevated risk based on the nature of their daily work. At a facility like the Penford Products starch plant, the following trades and union affiliations may have experienced the most serious asbestos-containing material exposure.

Insulators — Asbestos Workers Local 12 (Iowa)

Members of Asbestos Workers Local 12 working at or dispatched to the Penford Products facility may have faced the highest occupational asbestos exposure of any trade on site. Their work may have involved:

  • Cutting, trimming, and fitting asbestos-containing pipe covering from Johns-Manville, Owens-Illinois, and similar manufacturers to conform to pipe dimensions
  • Mixing and applying asbestos-containing insulating cement — in powdered or wet form — to pipe fittings and equipment
  • Removing old or damaged asbestos-containing insulation from Johns-Manville Kaylo, Thermobestos, or other products before repair or replacement
  • Working directly with asbestos-containing block insulation on boiler surfaces and equipment

Why insulators faced extreme exposure: Cutting asbestos-containing pipe covering with a saw or knife, and mixing asbestos-containing cement from a dry bag, generates visible clouds of airborne dust. Insulators who worked on or around asbestos-containing thermal insulation at facilities like Penford Products may have been exposed to extremely high concentrations of airborne asbestos fibers — potentially every single workday over the course of their careers.

Pipefitters and Steamfitters — UA Local 33 (Des Moines, IA)

Pipefitters and steamfitters from UA Local 33 who worked at the Penford Products facility installed, maintained, and repaired the facility’s steam and process piping networks. Their work may have exposed them to asbestos-containing materials from Johns-Manville, Owens-Illinois, and Crane Co. because:

  • Asbestos-containing pipe insulation had to be removed before pipefitters could access valves, flanges, and fittings for repair
  • Asbestos-containing pipe covering was routinely cut and disturbed during maintenance
  • Asbestos-containing valve packing — braided or compressed asbestos fiber — was regularly pulled and replaced
  • Asbestos-containing gaskets at flanged connections were cut, installed, and removed as part of routine work
  • Working in confined spaces alongside insulators, or in areas where asbestos-containing dust had settled, created ongoing fiber inhalation risk

Boilermakers — Boilermakers Local 83 (Kansas City, MO)

Boilermakers from Local 83 built, maintained, and repaired the industrial boilers providing process heat and steam at the Penford Products facility. Their exposure to asbestos-containing materials may have included:

  • Working inside and around boiler fireboxes lined with asbestos-containing refractory materials
  • Removing and replacing asbestos-containing boiler gaskets, rope seals, and door seals
  • Disturbing asbestos-containing block insulation from manufacturers such as Johns-Manville during boiler overhauls and repairs
  • Breathing airborne dust generated when hot insulation was broken away from boiler surfaces

Millwrights and Maintenance Mechanics

Millwrights and maintenance mechanics who kept the Penford Products facility running may have encountered asbestos-containing materials across multiple systems:

  • Maintaining and repairing insulated pumps, compressors, and rotating equipment
  • Disturbing asbestos-containing insulation while accessing equipment for repair
  • Working in mechanical rooms and equipment areas where asbestos-containing materials were present on surrounding systems
  • Handling asbestos-containing gasket material when disassembling and reassembling flanged equipment
