KDHE expects Neodesha refinery cleanup study filing by late summer

A corrective-action study for the former Amoco refinery in Neodesha is being prepared, with the Kansas Department of Health and Environment anticipating submission between late July and August 2026. The filing would be the next documented milestone in the state’s ongoing cleanup process for the Neodesha Refinery.

As of Aug. 7, 2026, the completed study had not been located, so the expected submission should not be treated as a filing already made. KDHE’s public refinery page also does not provide contamination levels, remedy alternatives, estimated costs or a completion schedule.

What the study could clarify

A corrective-action study could give residents, regulators and Neodesha officials more information about contamination at the industrial site, possible cleanup remedies, monitoring and future use of the property. Those are potential implications of the study process, not confirmed outcomes.

The anticipated filing does not establish that contamination has been remediated or that a specific remedy has been selected. The available information also does not show that the property will be closed, that an evacuation or redevelopment decision has been made, or that taxpayers will face a particular cost.

The state identifies the location as the Neodesha Refinery, formerly the Amoco Refinery. The site is in Neodesha, the Wilson County city named in KDHE’s cleanup materials.

City records show activity during the expected window

Neodesha’s official city-document archive lists commission agendas dated July 8, July 16 and July 22, 2026. The July 16 record is identified as a special-call agenda. Those records confirm active municipal business during the same period in which KDHE anticipated the study’s submission.

The city agendas, however, do not establish that the commission has taken final action on the refinery cleanup or that it has received the completed study. The state’s expected filing remains a regulatory and environmental milestone rather than a final cleanup decision.

For Neodesha residents and officials, the next known step is the study’s anticipated submission by late July through August 2026. The filing, if submitted, could inform later remediation and land-reuse decisions. Until it is available, the record does not establish the cleanup approach, its cost or when work would be completed.
