Sustainability

Environment

Protecting the environment is central to everything we do, from the way we design and build our facilities to where we locate them. We protect water resources through the responsible handling of waste. Our landfills are designed with sophisticated liners and modern, automated leak detection systems to protect against leachate leaks and are equipped with advanced technology to monitor groundwater. Water is an important component in Milestone’s operations. We make every effort to reuse water from appropriate sources while minimizing the use of fresh water. Most of the water we utilize in our slurry injection operations is produced from saltwater and flowback from our E&P customers.

Milestone’s air emissions include relatively small amounts of non-methane volatile organic compounds and other hazardous air pollutants emitted during the receipt, handling, temporary storage, processing, and disposal of waste at our slurry facilities and landfills. These nominal emissions are more than offset by the vast amounts of carbon sequestered via our daily operations, achieving a net-negative result.

Community engagement

Milestone remains steadfast in its commitment to give back to the communities in which we live and operate and to make a lasting impact in the neighborhoods our customers, employees, and other stakeholders call home. We design our facilities to readily accommodate excess truck traffic during surges to keep congestion off our community highways and byways.

Milestone also gives back to the community by supporting those who need it the most. Through direct monetary donations, sponsorships, and community event participation, we partner with a variety of nonprofit organizations to help tackle hunger, support first responders and veterans, and assist families in need. We also support community STEAM (Science, Technology, Engineering, Art, and Math) education events for children and multiple other children’s charities. 

Health & Safety

Milestone is committed to the health and safety of our workforce and the communities where we operate. Our goal is to ensure everyone, everywhere, is safe every day. Our commitment to safety is embedded in our values, and our safety culture is continuously reinforced by executive leadership and management. Our deeply ingrained safety culture empowers all those on the job to create a safe environment and stop work immediately if unsafe conditions arise. We provide extensive ongoing safety training, and we continuously audit our protocols for adherence and improvement. 

2024 Sustainability Report

Our 2024 Sustainability Highlight Report showcases Milestone's shift to a "Beyond Reporting" approach that prioritizes value creation at every level. The Report demonstrates how we're pausing extensive reporting to focus on sustainability initiatives that truly matter, allowing us time to identify new value channels as we grow. Building on our established foundations, including our triple-verification framework and value creation methodology, we're concentrating on effective implementation and transparent performance metrics that drive long-term value for both our company and stakeholders.
