Sustaining Our Safety Culture

In addition to providing high-quality training, Occidental also encourages innovation to reinforce our culture of safety.

People Observing Work for Risk Reduction, also known as "Enhanced Power2", teaches behavior-based safety observation in order to reinforce effective safety habits and encourage peer support and accountability. Participants learn to identify and document situations and behavioral factors that either pose, or reduce, a safety risk. The resulting feedback is continuously analyzed for trends and drives future training.

Targeting Occidental managers, supervisors and contractors, Occidental's Permian operations offer an intensive two-day program on Essentials of Safety Leadership Training. The course, developed with outside safety experts, blends conceptual content with practical breakout sessions. More than one thousand of the Permian Basin staff and contractors have participated in the program.

Occidental's Permian Basin employees created a web-based Safety Toolbox to share information, video lessons and performance metrics. In addition, to further encourage participation, employees have established a recognition program to acknowledge colleagues for innovative projects such as the development of a well control simulator. The program also recognized similar projects submitted by contractor service companies.

In 2011, Occidental enrolled more than 50,000 acres in a state-sponsored voluntary initiative to protect habitat for two species, the Dunes Sagebrush Lizard (Sceloporus arenicolus) and the Lesser Prairie Chicken (Tympanuchus pallidicinctus). Occidental's voluntary efforts occur through formal conservation agreements developed through a collaboration among the oil and gas and ranching industries, the State of New Mexico, the U.S. Fish and Wildlife Service (FWS), the Bureau of Land Management (BLM) and the Center of Excellence for Hazardous Materials Management, which administers the program. These agreements guide the implementation of conservation measures, including habitat restoration and enhancement and minimizing surface disturbance that are above and beyond those established by the BLM in its "Special Status Species Resource Management Plan Amendment" for southeast New Mexico to benefit these species.

In 2014, Occidental enrolled additional acreage under the existing New Mexico agreement to continue supporting conservation measures for the Lesser Prairie Chicken and the Dunes Sagebrush Lizard. Occidental's committed acreage is greater than 330,000 acres in New Mexico on both Federal and private lands. Occidental also enrolled significant acreage (approximately 300,00 acres) in its oil and gas interests in Texas under the voluntary Range-Wide Oil and Gas Industry agreement for the Lesser Prairie Chicken, which was developed in coordination with the U.S. Fish and Wildlife Service and the Western Association of Fish and Wildlife Agencies (WAFWA). The Range-Wide Oil and Gas Industry agreement represents a collaborative approach to facilitate responsible oil and gas development and habitat conservation for the Lesser Prairie Chicken species throughout the bird's range.

Under all of the voluntary agreements, Occidental follows the best practices to preserve Lesser Prairie Chicken and Dunes Sagebrush Lizard habitat during oil and gas development.

In June 2012, the U.S. Fish and Wildlife announced, "As a result of unprecedented commitments to voluntary conservation agreements now in place in New Mexico and Texas that provide for the long-term conservation of the dunes sagebrush lizard, the U.S. Fish and Wildlife Service has determined that the species does not need to be listed under the Endangered Species Act."

WAFWA has been conducting anual range-wide aerial surveys since 2011. In June 2017, WAFWA published a press release stating, in part, "The latest lesser prarie-chicken survey shows bird population trends remain stable after six years of aerial survey data collection. The survey indicates an estimated breeding population of 33,269 birds this year, up from 24,648 birds counted last year." To date, the Lesser Prairie Chicken remains an unlisted species under the Endangered Species Act.

Lower North Potato Creek Watershed Tennessee

Lower North Potato Creek Watershed Project (Polk County) - Glenn Springs Holdings Inc., the Tennessee Department of Environment and Conservation and the United States Environmental Protection Agency has been remediating the environmentally degraded Lower North Potato Creek Watershed for the past 14 years. Dating back to the 1850s, the watershed, part of the Copper Basin in Polk County, was a site of extensive copper mining and processing. To improve the water quality and biological integrity and diversity, Glenn Springs Holdings Inc. has installed and is maintaining fences to restrict access to designated hazardous areas, removed and isolated waste materials, constructed passive and active water treatment systems, captured poor quality water for treatment, diverted water of good quality, enhanced vegetation and wildlife habitat and restored stream segments and wetlands. In 2014, modifications were made to the North Potato Creek Wastewater Treatment Plant to facilitate processing of contaminated water for metal removal before being discharged to the Ocoee River.

Eureka Roast Yard: Acid-producing materials were removed and the area was capped and vegetated.

Mukhaizna Clinic: Vital Regional Resource

The Mukhaizna Clinic is one of the primary means by which Occidental of Oman demonstrates its commitment to the well-being and social welfare of its workforce, neighboring communities and the Sultanate of Oman.

Occidental Oman opened the clinic on September 1, 2005, as a healthcare facility for personnel working at the nearby Mukhaizna Field. In addition to Occidental employees, contractors and their families, the Mukhaizna Clinic offers its full complement of services and care to local residents.

With the nearest government clinic approximately 100 kilometers (62 miles) away, area residents are taking advantage of the Mukhaizna Clinic's proximity and wide range of services.

After passing through the welcoming entrance, patients find a waiting room, a doctor's office, an emergency room and an additional treatment room. The clinic is equipped to handle everything from routine doctor visits to emergency operations.

Thriving production at the Mukhaizna Field and area population growth make our Mukhaizna Clinic a vital regional resource - not only for providing urgent medical care, but also in promoting safety and wellness in the workplace and the broader community.

Promoting Safety in Neighboring Communities

To promote safety, local development and economic growth, Occidental Colombia has implemented a comprehensive training program on health, environment and safety (HES) topics for residents in the Llanos Norte area. HES advisors from several operational contractors volunteer their expertise and partner with Occidental-supported foundation El Alcaraván to present the training sessions.

In addition to covering human rights and environmental management planning, the training includes use of personal protection equipment, fire theory, handling of chemical products, dangers and risks, and emergency planning. The sessions provide the attendees with basic training and knowledge that also helps to prepare them for job opportunities at Occidental.

Taking into account the literacy level of the area, Occidental proactively adapted its training materials to ensure the contents are understandable for all trainees. In collaboration with SENA (the Colombian Government's National Technical Training Service), Occidental has designed additional training courses to foster the implementation of safe practices, both at work and at home.

Focus on Controlling Greenhouse Gas (GHG) Emissions

Occidental is a leader in carbon dioxide (CO2) injection for enhanced oil recovery (EOR), which could play a major role in developing and validating national carbon dioxide sequestration strategies to reduce GHG emissions. Occidental is focused on managing GHG emissions from its other operational activities. Occidental's operations make extensive use of natural gas as an energy source, instead of fuels with higher GHG emission factors. Also, Occidental operates several highly efficient cogeneration plants for electrical power and steam to supply its oil and gas and chemical operations. Cogeneration reduces carbon dioxide emissions by a significant degree compared to standalone power and steam generation units. Occidental has been recognized by the U.S. EPA for its longstanding and active efforts to bring methane to natural gas markets, rather than flaring or emitting it to the atmosphere.
