Asset Retirement Obligation Disclosure [Abstract]
Asset Retirement Obligations	6. Asset Retirement Obligations We own the land on which our owned plants operate, limiting asset retirement obligations at our owned chemical facilities. However, we have various legal requirements related to operations at our chemical facilities mainly for the disposal of wastewater generated at certain of these facilities. At December 31, 2021 and 2020, our accrued liability for AROs was $100,000. However, the facilities and some of the water related assets have an indeterminate life and as a result there is insufficient information to estimate the fair value for certain of our AROs. We will continue to review these obligations and record a liability when a reasonable estimate of the fair value can be made.

The entire disclosure for an asset retirement obligation and the associated long-lived asset. An asset retirement obligation is a legal obligation associated with the disposal or retirement from service of a tangible long-lived asset that results from the acquisition, construction or development, or the normal operations of a long-lived asset, except for certain obligations of lessees.
