Manufactured Gas Plant

In 2008, we acquired whole and partial liabilities for former manufactured gas plant sites in Nebraska and Iowa, which were previously used to convert coal to natural gas. The acquisition provided for an insurance recovery, now valued at $1.4 million recorded in Other assets, non-current on our Consolidated Balance Sheets, which will be used to help offset remediation costs. During the six months ended June 30, 2024, we increased our Iowa manufactured gas plant site remediation cost estimate by $7.4 million based on recent site investigations and remediation work completed, which resulted in a corresponding increase in our Accrued liabilities and Regulatory assets. As of June 30, 2024, we had an Accrued liability of $11.5 million and a Regulatory asset of $10.6 million on our Consolidated Balance Sheets for the remediation of the manufactured gas plant site in Iowa. The remediation cost estimate could change materially due to results of further investigations, actions of environmental agencies or the financial viability of other responsible parties.
