Biodiversity and Ecosystem Protection

Healthy habitats and ecosystems are vital to a thriving world. Crestwood works to minimize our impacts, reduce long-term habitat disturbances and integrate biodiversity conservation efforts into our land use management. Biodiversity and ecosystem protection remains a strategic focus of the company and a key component of our sustainability strategy.

Our Approach

Our goal is to be an MLP midstream industry leader in biodiversity and ecosystem protection by upholding the strategic and responsible practices described in our Biodiversity Policy. The policy, developed in 2020, contains provisions on sustainable management of natural resources and raw materials as well as respecting Indigenous peoples and minimizing community impacts. 

The Environmental Services department, with support from the Land Services department and Operations team, manages Crestwood’s land use practices, entrenched in protecting and conserving the biodiversity in areas where we operate.

Protecting and conserving a habitat or species requires stakeholder inclusion and collaboration. We are committed to applicable regulations, best practices and exceeding the expectations of landowners. Our teams work regularly with government entities such as the EPA, the U.S. Fish & Wildlife Service, the Bureau of Land Management, U.S. Army Corps of Engineers, Federal Energy Regulatory Commission, National Park Service, Bureau of Indian Affairs and tribal, state and local permitting and wildlife management agencies to define management plans and minimize impacts. 

Restoration at all our sites is a vital part of our approach to Biodiversity. Each year, Crestwood reclaims numerous rights-of-way (ROW) that have been temporarily disturbed to facilitate pipeline construction projects. These projects vary in length, geographic orientation and soil type. Recognizing the importance of land reclamation on biodiversity, Crestwood’s Environmental Services team manages land reclamation as a stand-alone scope of work and employs the services of specialty reclamation contractors to facilitate successful reclamation efforts. Topsoil is segregated during ROW clearing and is separated from subsoil throughout construction. Following pipeline installation, Crestwood ensures pre-construction contours are restored and topsoil is properly redistributed across the ROW. Erosion control devices are utilized both during and after construction to minimize erosion and topsoil loss. Seed mixes are customized for each project based on input from landowners and regulatory agencies. Once seeded, ROWs are regularly monitored for restoration success and noxious weeds. Correction actions plans, if necessary, are developed and implemented based on inspection findings.

During project design, Crestwood takes a mindful approach in developing project routing and workspace planning. Routing, workspace design and construction methodologies are employed that avoid and/or minimize impacts to sensitive habitats such as wetlands, waterbodies, wooded areas and native grasslands. In non-agricultural areas, native seed mixes are designed and implemented post-construction to expedite reclamation and restore biodiversity. Noxious weed monitoring and control plans are implemented in sensitive areas subject to potential noxious weed encroachment. This management program allows for the reestablishment of natural vegetative communities, and the associated fauna that rely on them.

To monitor our awareness of any sensitive biodiversity areas within the lands we operate, we track the percentage of lands within a 30-foot average corridor of a pipeline’s centerline in proximity to areas designated by the U.S. Fish and Wildlife Service as threatened and endangered species habitats.

Strategic Environmental Partnerships

Crestwood understands that long-lasting, meaningful conservation requires commitments from a variety of stakeholders. Therefore, we cultivate environmental stewardship partnerships in key operating locations at the community, state and federal level. In 2021, we engaged with the local Indigenous community in North Dakota, solicited expert advice from local remediation specialists, partnered with state-led conservation organizations and sought and received certification from the Wildlife Habitat Council (WHC). Our approach to our team’s grassland reclamation work was further recognized through the WHC’s 2021 Grassland Award.

Texas Hornshell Mussel Habitat Conservation Efforts

In the Black River and Delaware sub basis of the Permian Basin, Crestwood is a participant in the Candidate Conservation Agreement (CCAA) with Assurances for the Texas Hornshell (Popenaias popeii) and other Covered Species (Rio Grande River Cooter (Pseudemys gorzugt), Gray Redhorse (Moxostoma congestum), Blue Sucker (Cycleptus elongatus) and Pecos Springsnail (Pyrgulopsis pecosensis). In addition to adhering to construction best management practices designed to minimize impacts, we contribute habitat conservation funding for projects completed within the CCAA defined management zone. This funding is used for habitat improvement and enhancement projects designed to benefit the Texas Hornshell, among other species.

Cheatgrass (Invasive Species) Control

In 2021, we partnered with Converse County to control the spread of the invasive species and wildfire fuel, Cheatgrass (Bromus tectorum). We applied a targeted treatment on over 258 acres on our Jackalope system to limit the growth and spread of this invasive species.

Wildlife Habitat Council (WHC) Best Grasslands Award

In late 2020, we applied for our first certification of a grassland restoration project with the WHC. The project involved enhanced reclamation activities for three recently completed pipeline projects in North Dakota. We received certification for that project in early 2021. In June, Crestwood received notice of recognition for the best grassland project at the 2021 WHC Annual Awards Ceremony.

Raptor Nesting Season Avoidance

In Wyoming, we completed the Continental Express Pipeline project, a 21-mile pipeline construction project, including post-construction reclamation activities. We achieved this in a record pace of three months, with the schedule specifically designed to avoid avian nesting season and potential impacts to nesting raptors (Golden eagles, red tail hawks) located in the project vicinity.

Aquatic Invasive Species Control

In 2021, we donated $20,000 to the Wyoming Game and Fish Department to support efforts to control the zebra mussel (Dreissena polymorpha) population, an aquatic invasive species in eastern Wyoming. These invasive mussels are prolific and can remove nutrients from water, clog pipes and waterways, damage boats and out-compete native mussels. 

Internship Program: Strengthening Indigenous Relations

In the summer of 2021, Crestwood selected Francis Short Bull from Nueta Hidatsa Sahnish (NHS), a fully accredited Tribal College, to work as an intern with our environmental services team. His internship in North Dakota supported our reclamation programs, noxious weed control and remediation programs while strengthening Crestwood’s relationship with the MHA Nation. 


Crestwood Voice

I appreciated and valued the environmental and reclamation experiences while working with the Crestwood team. Being a part of the planning process and decisions affecting my ancestral lands was a powerful educational opportunity.

Cultural Heritage Protection

Our focus on minimizing impacts of our operations goes beyond flora and fauna. We include the cultural landscapes of the areas in which we operate. At the start of the routing or siting process, we examine the potential presence of recorded cultural resources along the proposed pipeline route or operational site. The results of this due diligence guide the extent of any additional research or adjustments necessary for the routing or siting process. We work to minimize our construction footprint, specifically managing our developments to avoid impact to cultural resources.

If potentially significant cultural resources are identified in proximity to proposed pipeline routes or facilities, Crestwood works with the appropriate state Tribal Historic Preservation Office to avoid or minimize any potential impact. This includes following processes outlined in Crestwood’s Unanticipated Discovery Plans for projects executed in North Dakota and Wyoming. In 2022, we will develop a similar plan for a project located in the Delaware Basin.
