Environmental Remediation Obligations [Abstract]  

The Company's operations are subject to various federal, state and local laws and regulations relating to the protection of the environment.  These laws and regulations impose limitations on the discharge of materials into the environment and require the Company to obtain and operate in compliance with conditions of permits and other government authorizations.  As such, the Company has developed environmental, health and safety policies and procedures that include the proper handling, storage and disposal of hazardous materials.

The Company is party to various environmental matters.  These include obligations to investigate and mitigate the effects on the environment of the disposal of certain materials at various operating and non-operating sites.  The Company is currently performing environmental assessments and remediation at these sites, as appropriate.

At September 30, 2017, an accrual of $2,928 had been recorded for environmental remediation (of which $750 was classified in other current liabilities), representing management's best estimate of the probable and reasonably estimable costs of known remediation obligations for one of the Company's subsidiaries.  The accrual does not consider the effects of inflation and anticipated expenditures are not discounted to their present value.  While final resolution of these contingencies could result in costs different than current accruals, management believes the ultimate outcome will not have a significant effect on the Company's consolidated results of operations or financial position.
