6. Environmental Liabilities and Expenditures

Occidental’s operations are subject to stringent federal, state, local and foreign laws and regulations related to improving or maintaining environmental quality.

The laws that require or address environmental remediation, including the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and similar federal, state, local and foreign laws, may apply retroactively and regardless of fault, the legality of the original activities or the current ownership or control of sites.  OPC or certain of its subsidiaries participate in or actively monitor a range of remedial activities and government or private proceedings under these laws with respect to alleged past practices at operating, closed and third-party sites.  Remedial activities may include one or more of the following:  investigation involving sampling, modeling, risk assessment or monitoring; cleanup measures including removal, treatment or disposal of hazardous substances; or operation and maintenance of remedial systems.  Government or private proceedings seek funding or performance of remediation and, in some cases, compensation for alleged property damage, punitive damages, civil penalties, injunctive relief and government oversight costs.

As of September 30, 2014, Occidental participated in or monitored remedial activities or proceedings at 153 sites.  The following table presents Occidental’s environmental remediation reserves as of September 30, 2014, the current portion of which is included in accrued liabilities ($78 million) and the remainder in deferred credits and other liabilities — other ($252 million).  The reserves are grouped as environmental remediation sites listed or proposed for listing by the United States Environmental Protection Agency on the CERCLA National Priorities List (NPL sites) and three categories of non-NPL sites — third-party sites, Occidental-operated sites and closed or non-operated Occidental sites.

	Number of Sites	Reserve Balance (in millions)
NPL sites	30	$	24
Third-party sites	72	94
Occidental-operated sites	19	110
Closed or non-operated Occidental sites	32	102
Total	153	$	330

As of September 30, 2014, Occidental’s environmental reserves exceeded $10 million each at 11 of the 153 sites described above, and 103 of the sites had reserves from $0 to $1 million each.  Based on current estimates, Occidental expects to expend funds corresponding to approximately half of the current environmental reserves at the sites described above over the next three to four years and the balance at these sites over the subsequent 10 or more years.  Occidental believes its range of reasonably possible additional losses beyond those liabilities recorded for environmental remediation at these sites could be up to $390 million.  The status of Occidental’s involvement with the sites and related significant assumptions has not changed materially since December 31, 2013.  For additional information regarding environmental matters, refer to Note 7.
