Statement of Complaint:

I want to file a complaint of horrible industrial air pollution in Fairfield that, in my professional experience, is the characteristic air emissions of a Grey Iron Foundry based on numerous inspections of the industry in Texas during twelve years with the state of Texas air pollution control agency.

My complaint is also based on professional knowledge of the highly toxic chemicals emitted by the Grey Iron Foundry sector and the organic chemical byproducts of incomplete combustion including toxic metals during the standard operations and practices in this industrial sector as identified by the Environmental Protective Agency (EPA).

Moreover, the field of toxicology confirms the toxicity of Grey Iron Foundry sector emissions during maintenance, startup and shutdown plus routine recycled metals processing. Toxic air pollution from Grey Iron Foundry sites is a significant reason why EPA is regulating this industrial sector, although in my view, EPA’s air toxics standards need to be improved in order to better protect public health, because I have participated in the EPA rule making process of submitting public comments to the EPA docket and am concerned about legal loopholes in these rules.

As Iowa DNR knows, EPA identifies Iron and Steel Foundries as a major industrial source of hazardous air pollutant (HAPs) emissions and EPA has issued National Emissions Standards for Hazardous Air Pollutants (NESHAP) under its section 112(d) Clean Air Act authority. Under the Clean Air Act, major sources are required to meet HAP emissions standards that reflect the application of the maximum achievable control technology or MACT.

EPA itself emphasizes that exposure to substances from the Grey Iron Foundry sector, including the HAP metallic emissions and HAP organics, have been demonstrated to cause adverse health effects, including cancer and chronic or acute disorders of the respiratory, reproductive, and central nervous system.

June 11, 2026 on Thursday evening I was cycling heading south along North B street in NW Fairfield from 185th street at approximately 8:15 pm - 8:45 pm and began to notice a continuous toxic metallic smell of industrial air pollution being wind carried from the southwest that I have observed previously as characteristic of the HyCast Grey Iron Foundry’s fugitive and stack emissions.

On June 11, 2026 during cycling in Fairfield along North B street, I experienced a brief headache while smelling the continuous toxic metallic smell of industrial air pollution characteristic of the HyCast Grey Iron Foundry’s fugitive and stack emissions.

On June 11, 2026 as I cycled along North B street heading back north, I continuously observed the same HyCast metallic emissions air pollution, which is distinctly different from the outdoor burning of grass and wood debris and entirely different from local agriculture sites emitting hydrogen sulfide and other compounds.

Please note this is certainly not the first time in Fairfield that I have personally observed a continuous toxic metallic smell of industrial air pollution drifting through Fairfield that is characteristic of the HyCast Grey Iron Foundry’s fugitive and stack emissions, and similar air pollution emitted by prior foundry owners.

As Iowa DNR is aware, EPA reports that the Grey Iron Foundry sector recycles scrap metals and, as a result, is known to emit many HAP pollutants (organic and metals) and harmful Criteria pollutants including particulate matter (PM, PM10, PM2.5), nitrogen oxides, sulfur dioxide, carbon monoxide, volatile organic compounds, and the toxic heavy metal lead.

EPA further reports the speciation of the HAP chemicals into harmful elements and chemicals.

7/31/2026	I conducted an unannounced visit at HyCast on June 23, 2026 regarding the complaint. Based upon the their records, HyCast is pouring in the mornings only as the weather warms. They are making ~200 molds per day, approximately 2 tons of metal. The metal melts only through their induction furnaces. They are no longer utilizing the cupola as those activities associated at the plant are discontinued. After pouring, the induction furnaces are allowed to cool and maintained at a set temperature. In the early morning more metal is added and heated up for the day's pours. They are pouring 2-3 days per week. Regarding June 11, 2026 in particular. Rain events passed through the area in the morning and concluded around 1-2pm depositing about 1.25 inches of rain. The cold (low pressure) front passed through afterwards and winds primarily WNW at 10-15mph occurred. The winds could have carried odors (and the allowable emissions after the air pollution control equipment of bag filters) towards the areas Neil observed along B Avenue while bicycling. HyCast was done with all pouring by 1 pm on June 11. According to their staff the only operating equipment was the induction furnaces as the metal was still cooling from the melt from earlier part of the day. No heating of the metal occurred again until early on June 12 prior to 6AM.	RYAN STOUDER
