Introduction

Please give a general description and introduction to your organization.

Occidental's (Oxy's) principal businesses consist of the oil and gas exploration and production, chemical (OxyChem) and midstream and marketing segments. Oxy's operations are concentrated in the United States, the Middle East and Latin America regions. The oil and gas segment explores for, develops and produces oil and condensate, natural gas liquids (NGL) and natural gas. The midstream and marketing segment gathers, processes, transports, stores, purchases and markets oil, condensate, NGLs, natural gas and carbon dioxide, and generates power. OxyChem is a leading manufacturer of PVC resins, chlorine and caustic soda – key building blocks of products such as pharmaceuticals, water treatment chemicals and plastics. The production of oil and gas, electricity and chemicals requires water, and Oxy understands the importance of managing water resources responsibly. Occidental's water management program is designed to conserve and protect water resources in communities where we operate. Oxy is committed to respecting the environment, maintaining safety and upholding high standards of social responsibility throughout its worldwide operations.

Please explain

Sufficient amounts of good quality freshwater available for use

Vital for operations

Important

It is important to Oxy that we use all sources of freshwater responsibly. Where possible, Oxy does not use freshwater resources in conflict with local users. Oxy's oil production operations generate significant quantities of produced water (i.e., saline water from hydrocarbon reservoirs) which is often sufficient to meet the quantity of our needs. However, there are certain activities, such as hydraulic fracturing and water flooding for which the quality of recycled produced water is not sufficient. For those, Oxy requires freshwater. OxyChem’s business uses significant quantities of freshwater for production and cooling purposes. With respect to indirect use, freshwater is used to meet worker’s needs for cleaning and drinking purposes.

Sufficient amounts of recycled, brackish and/or produced water available for use

Neutral Not very important

With respect to direct use, Oxy’s oil and gas operations increasingly substitute freshwater resources with brackish/non-potable produced water, naturally occurring water that originates in the hydrocarbon reservoir and comes to the surface along with oil and gas during production. In 2015, 60% of water needs were sourced using non-potable water in our U.S. upstream operations. The extraction, processing, treatment and reinjection of produced water is integral to the design and efficient operation of Oxy’s mature oil and gas fields, including water flooding and EOR operations. At OxyChem, the manufacture of chlorine and caustic soda involves the extraction and processing of brine (saltwater) streams.

Comment

Annually Facility 1 to 3 years

An initial assessment is conducted prior to exploration in a new region. Water is integrated into a comprehensive, company-wide risk assessment process incorporating direct operations only. Minor incidental uses, such as in office buildings, are not included. Oxy's Health, Environment and Safety Management System (HESMS) requires an assessment of potential environmental effects at all new operations.

Every two years

Region 3 to 6 years

Facility or local level water risk assessments are cross referenced against longer-term (3-5 years, or longer) regional demographic and economic growth forecasts and risk of severe weather occurrences - i.e., drought, flooding and severe storm vulnerability - that potentially impacts staffing and our operational assets.

W2.4

Have you evaluated how water risks could affect the success (viability, constraints) of your organization's growth strategy?

Yes, evaluated over the next 1 year

10

W2.4a

Please explain how your organization evaluated the effects of water risks on the success (viability, constraints) of your organization's growth strategy?

Oxy considers the longer-term patterns of integrated water resources management, regenerative capacity of ground water and aquifers, population growth/demand shifts and the potential for weather related impacts to evaluate and mitigate the effects of water risks on key operations and the safety and well-being of employees and contractors. When evaluating a new site or asset, this involves evaluating legal and regulatory issues and hydrological yield in terms of the reliability and proximity of other water users during exploration and production activities. The Company's analysis of water-related risks includes an information-gathering process, environmental due diligence, participation in industry association work groups (for example, Texas Oil and Gas Association, IPIECA Water Working Group and the American Chemistry Council Responsible Care) and stakeholder engagement to inform and refine our risk management and strategic planning processes. Also, water risk is evaluated based on the importance of water to an operation, and importance depends in part on how easily a particular source could be replaced with an alternate source, and technological feasibility and viability. Part of the evaluation also involves considering both quantity and quality characteristics of the source in use and of the potential alternatives. The importance level is factored into the risk identification and management process.

Method

Please explain how these methods are used in your risk assessment

CEO Water Mandate's 'Understanding Key Water Stewardship Terms' GEMI Local Water Tool IPIECA Global Water Tool for Oil & Gas Regional government databases WRI Aqueduct Other: World Economic Forum (WEF) Global Risks

Oxy’s water risk management approach assesses the risks and compliance measures associated with sourcing water in terms of adequate quantity and quality, the protection of water resources (e.g. proper well design and integrity), efficient use of water (reuse and recycling), and the disposal of wastewater and/or solid wastes. A variety of industry, scientific and third-party tools and risk assessments are used to cross-reference our internal HESMS risk management process. These external resources provide useful input and interject analyses and critical thinking that Oxy may not have considered relevant at the facility or business unit level. This is used for all our operations.

W2.6

Which of the following contextual issues are always factored into your organization's water risk assessments?

Issues

Choose option

Please explain

Current water availability and quality parameters at a local level

Relevant, included

Water quantity and quality parameters are factored into Oxy's risk management approach and HESMS. Occidental recognizes the localized nature of water management issues, as such, it may not be relevant to compare water risk parameters from one site to another because the availability and quality of water sources, as well as the demand for those water sources, varies significantly from place to place.

Current water regulatory frameworks and tariffs at a local level

Relevant, included

Current regulatory frameworks and tariffs at the local and municipal level are factored into our HESMS and water risk assessments.

Current stakeholder conflicts concerning water resources at a local level

Relevant, included

Oxy always seeks to optimize water from non-potable sources, using the lowest-quality water acceptable for operational activities, and recycles produced water and wastewater wherever feasible to avoid using water resources in conflict with local stakeholders.

Current implications of water on your key commodities/raw materials

Not relevant, included

Water risks on our raw materials are sufficiently addressed through diversity and security of suppliers.

12

Issues

Choose option

Please explain

Current status of ecosystems and habitats at a local level

Relevant, included

Local ecosystem and watershed impacts are factored into our HESMS and water risk assessments. In many operations, Oxy has set aside habitat conservation areas or has contributed to local and regional habitat conservation efforts.

Current river basin management plans Not relevant, explanation provided

River basin management plans are considered, if robust and available. The use of external risk assessments and spatial modelling tools (WRI Aqueduct, IPIECA Global Water Tool) can substitute for government sponsored river basin plans.

Is your organization exposed to water risks, either current and/or future, that could generate a substantive change in your business, operations, revenue or expenditure?

15

Yes, direct operations only

W3.2

Please provide details as to how your organization defines substantive change in your business, operations, revenue or expenditure from water risk

Oxy's HESMS and risk management approach identifies, assesses and grades significant (actual and potential) water related risks. The HESMS sets consistent worldwide performance expectations and standards across each business segment's respective operations. The HESMS facilitates compliance with laws and regulations and the management of HES and water-specific risks to improve overall business performance. Oxy manages its own water use consistent with community interests near our operations and to avoid adversely impacting the environment, or our license to operate in these communities. For example, water scarcity is a prominent issue in the Permian Basin (West Texas and Southeast New Mexico) where, as reported by the U.S. Geologic Society and Texas Alliance, the majority of oil and gas wells are in a “high or extremely high water stress area.” These prevailing water scarcity risks are factored into Oxy’s business plans and water use strategy to operationalize and mitigate risks, and also to identify and seize opportunities that could provide costs savings or generate revenues. Oxy’s form 10-K provides a detailed discussion of risk factors, including those which can be water-related such as governmental actions, climate change and catastrophic events (hurricanes, floods and droughts).
