About NuStar

Resilience in 2020 and Achieving Our 20th
Year of Sustainability Excellence in 2021

2020 was all about resilience, protecting our employees and serving our communities. We are proud of our response to the COVID-19 pandemic and achieving our 20th year of sustainability in 2021.

Company Overview

NuStar Energy L.P. is one of the largest independent liquids terminal and pipeline operators in the nation, responsibly storing and distributing the renewable and biofuels, refined products, crude oil and specialty liquids needed across North America. Headquartered in San Antonio, Texas, as of December 31, 2021, NuStar had approximately 10,000 miles of pipeline and 64 terminal and storage facilities and our combined system had roughly 57 million barrels of storage capacity. We have operations in communities across the United States and in Canada and Mexico, with approximately 1,250 employees.

NuStar’s 20 years of dedication to our communities, sustainability and resilience is a result of our strong corporate culture, which reflects the vision and leadership of our Chairman, Bill Greehey, and NuStar’s nine Guiding Principles.

Our Guiding Principles lay out our expectations for how we conduct ourselves with regard to each other, the environment, our communities and our customers and business partners. As a result of our strong culture and our Guiding Principles, NuStar has been recognized with numerous awards over the last 20 years, including being recognized 12 times as one of FORTUNE Magazine’s "100 Best Companies to Work For" and receiving the International Liquids Terminals Association’s (ILTA) Safety Excellence Award 11 times. Our resilience not only ensures that NuStar continues to provide safe, reliable and affordable access to fuels, but also ensures that we continue to support our employees and build value for our investors.

Service to Our Communities

We are proud to be a part of an industry that provides the most environmentally responsible and safest way to transport the reliable fuels our nation needs at an affordable price, creates jobs, keeps the economy moving and allows people to live comfortably. The fuels we transport and store are used throughout society to support essential services such as our first responders and the military. We are proud to have served our communities for 20 years.

We believe no one should go without affordable and reliable fuels. History has shown that sharp increases in fuel costs can be disproportionately detrimental to the poor and minorities. Just a 10% increase in household energy costs could potentially move approximately 840,000 people across the U.S. below the poverty line. Minority households are twice as likely to be forced into choosing between reducing or forgoing food or medicine to pay higher energy costs than the national average.[1]

We believe families should not have to choose between food and medicine and fuel, and we make it our mission to responsibly provide affordable, reliable and accessible fuels to all of the people in the communities we serve. This affordable and reliable energy is only possible with responsible transportation and storage of liquid fuels. Studies have shown that families save approximately $2,500 on energy every year because of fuels delivered by pipelines across the United States.[1]

In addition, while we have been responsibly providing affordable, reliable access to fuels for more than 20 years, studies show that our communities will need these affordable and reliable liquid fuels for many years to come. Pipelines are the most environmentally responsible and safest way to transport and store these liquid fuels that will continue to sustainably play a key role in the U.S. energy supply and supply around the globe for decades to come.

NuStar’s Headquarters: Designed and Built To Be Sustainable

Our corporate headquarters is located on a picturesque hilltop in North San Antonio. We created this space with our commitment to biodiversity and native ecosystems in mind. Approximately two-thirds of our 37-acre campus has been preserved and maintained as natural habitat for native plants and animals. Additionally, as part of the headquarters construction, we saved and replanted 15 legacy mature oak trees at Haven for Hope, a transformational homeless campus in the heart of downtown San Antonio. Our public utility has recognized us for saving approximately 1 million gallons of water per year and using an innovative recycled water system.

COVID-19 Pandemic Resiliency

While 2020 tested our resiliency, in responding to the COVID-19 pandemic, we drew on our Guiding Principles and our strong corporate culture as we continued to focus on responsibly providing the fuels needed by our nation and the protection of our employees, their families and our communities. As a provider of essential fuel services, we have continued to work to prevent interruptions to the access to affordable fuels, while still staying dedicated to outstanding safety performance and environmental stewardship.

We took several actions based on our first Guiding Principle of “Safety” in our workplaces to protect our employees, including integrating the recommendations from both the Centers for Disease Control and Prevention (CDC) and the Occupational Safety and Health Administration (OSHA) into our protocols. We safeguarded employee health throughout our COVID-19 response by implementing physical distancing and staggered shifts, restricting facility access and incorporating thorough cleaning protocols at worksites. Additionally, we invested in ventilation and air-handling improvements, provided free COVID-19 testing and vaccines to employees at our headquarters and provided vaccine sourcing information to all field sites.


While protecting our workforce and ensuring reliable delivery of essential fuels, NuStar and our Chairman also pledged over $1 million to community relief funds to ease the impacts of COVID-19 in our communities.


In addition, we drew on our Guiding Principle of “Communication” to focus on timely, comprehensive communication between executive management and our employees. We conducted daily meetings with our human resources support teams to ensure top-down communication of COVID-19 updates to all employees. Additionally, NuStar leadership regularly checked in with industry peer groups and organizations to ensure our employees stayed up-to-date on developing best practices. By taking these extra steps we were able to assure a safe working environment for our field and control room employees who continued to work in person to provide essential services.

As a result of these actions, based on OSHA’s reporting requirements, NuStar had zero confirmed work-related transmissions of COVID-19 and no COVID-19 related curtailments of services during 2020.

Our Continuing Tradition of Sustainability and a Resilient 2020

Building on 20 years of sustainability excellence, NuStar is committed to environmental, social and governance (ESG) excellence and proud to publish our inaugural Sustainability Report. Although we have always strived for sustainability, in 2019, we formed an “ESG Task Force” to explore our sustainability reporting and assure best practices. To enhance our efforts, in 2020, we created our “Sustainability Working Committee” to focus on enhancing our sustainability disclosures. Earlier in 2021, in preparation for this inaugural Sustainability Report, we also launched our Sustainability Webpage and expanded our ESG disclosures by providing an additional focused ESG slide presentation.

Our Sustainability Report highlights our performance and is informed by guidance from the Energy Infrastructure Council (EIC) and the Sustainability Accounting Standards Board (SASB). While liquid pipeline and storage operations do not result in a significant contribution to the direct production of Greenhouse Gases (GHG) (see our expanded discussion in our Environmental and Safety section later in this report), we have already started the process of formalizing the collection of our GHG Scope I and Scope II emissions data.

Unless otherwise noted, all information, data and metrics in this report are as of December 31, 2020.
