Schedule of Environmental Loss Contingencies by Site

Total costs that may be incurred in connection with addressing these sites cannot be determined at this time. The estimated accrued costs are limited to CenterPoint Energy’s and CERC’s share of the remediation efforts and are therefore net of exposures of other PRPs. The estimated range of possible remediation costs for the sites for which CenterPoint Energy and CERC believe they may have responsibility was based on remediation continuing for the minimum time frame given in the table below:


	March 31, 2024
	CenterPoint Energy		CERC
	(in millions, except years)
Amount accrued for remediation	$	13	$	11
Minimum estimated remediation costs	8		7
Maximum estimated remediation costs	47		40
Minimum years of remediation	5		5
Maximum years of remediation	50		50
