"Crestwood is proud to be a leading MLP midstream company with the early issuance of a sustainability report, demonstrating our long-term commitment to sustainability and our best-in-class approach to environmental stewardship, safety and community relations," said Robert G. Phillips, Chairman, President and Chief Executive Officer of Crestwood's general partner. "Our approach to sustainability takes into consideration the interest of all of our stakeholders ? from those who invest in us, work for us and partner with us, to those who live near our projects and operations. Our strategy is to identify ESG risks and opportunities most significant to our business and integrate them into our strategic framework and capital allocation decisions, which will help us deliver solid financial results and position us to grow and prosper in the long-term."

Highlights in Crestwood's 2018 sustainability report include:

• Crestwood's materiality assessment: Crestwood conducted its first materiality assessment to identify, assess and prioritize the ESG topics that are most significant to the business and its stakeholders. Led by third-party consultants, the assessment process identified 12 material topics that shaped the report content and key performance indicators.
• Three year sustainability strategy: Crestwood identified five key sustainability focus areas that represent not only risks to be managed, but also significant opportunities. These include: Supply Chain Management, ESG Investor Strategy and Disclosure, Environmental Stewardship, Diversity and Inclusion, and Social Investment. These focus areas are aligned with Crestwood's business goals, while also being responsive to its stakeholders.
• Ensuring the safety of employees and contractors: Crestwood's safety performance was strong in 2018, with improvements in its leading and lagging indicators. Crestwood saw a 9 percent reduction in its Total Recordable Incident Rate and a 59 percent reduction in its Preventable Vehicle Incident Rate for employees and contractors.
• Reducing operational footprint: Crestwood is focused on minimizing habitat disturbances and is implementing leak detection methods to improve operational efficiencies and reduce emissions.
• Building resilient relationships with communities: Since 2013, Crestwood has invested over $2 million in long-term economic development projects in North Dakota that enhance local access to healthcare and early childhood education in addition to annual sponsorships of community and tribal events.

Crestwood's first sustainability report has been prepared in accordance with the Global Reporting Initiative (GRI) Standards: Core option.
