We believe our commitment to environmental stewardship is not only a moral obligation, but also makes good business sense, and helps drive the success of our projects and operations company-wide. We want our neighbors to know that protection of the environment is a priority and we continuously evaluate and strive to reduce environmental risks, which can affect our business and the community.
Enterprise is committed to being a responsible steward of the environment. Our Environmental Policy is focused on minimizing the impact of our operations, improving our operational efficiency, and protecting the environment. A copy of our Environmental Policy is available on the Code of Conduct & Related Policies page of our website.
We actively seek opportunities to restore essential tidal marsh habitat by supplying private and government entities with suitable material dredged from our marine facilities. Enterprise’s involvement has helped restore essential tidal marsh habitat that has been significantly lost to subsidence and other factors over the last several decades. Our most recent example occurred along the banks of the Houston Ship Channel. The San Jacinto monument, a 567-foot limestone obelisk topped with a 220-ton star structure, marks the spot of the decisive battle for Texas independence in 1836. Since 1994, the Texas Parks and Wildlife Department (TPWD) has been working to restore the San Jacinto battleground to its original appearance. The project is designed to give visitors a more accurate picture of the landscape that existed at the time and a better appreciation of how those conditions impacted the battle. Enterprise supported this initiative by providing more than 475,000 cubic yards of dredging material from our Morgan’s Point ethane export terminal which went into service in 2016. The fill material was used to raise a 100-acre area of the battleground that had subsided over the years. Restoration efforts have allowed the reestablishment of native grasses that were once characteristic of the marsh, which will increase the habitat for birds, small mammals and several marine species. The project will also facilitate the creation of a pedestrian trail. Another benefit of restoring the marsh is protection of the site against storm surges such as those caused by Hurricanes Ike in 2008 and Harvey in 2017. In commenting on the public/private partnership, TPWD State Parks Director Brent Leisure said, “It’s a great example of how industry can continue to operate in the area while helping to restore and maintain the natural and cultural heritage of the San Jacinto Battleground.”
As a result of the strong teamwork between Enterprise, TPWD, the U.S. Army Corps of Engineers, the Texas Historical Commission and contractors Atkins and Weeks Marine, Inc., this initiative earned the Environmental Excellence in Navigational Dredging Award in 2017.
"I am very proud of the performance of our employees involved in this project, especially their commitment to environmental stewardship and completing the job safely," said Jim Teague, chief executive officer of Enterprise’s general partner. "This initiative is consistent with Enterprise’s philosophy of pursing creative solutions that meet the goals of the company and its partners."
Some of the more substantial challenges associated with the project were:
- Accelerated schedule – only 20 months from design to completion
- Dredge material – comprised mainly of medium-to-stiff plastic clays intermixed with fine sand and silt
- Transport distance – dredge material transported 9.7 miles from Morgan’s Point terminal to 150-acre marsh site
- Utilities – active infrastructure network bisected work locations
- Cultural resources – significant concentrations of artifacts
- Active construction site – ongoing development of Morgan’s Point dock required continuous coordination between dredging and construction equipment
- Freshwater inputs – three upland freshwater sources drain through the site, requiring careful management of water flow
- Weather – record flooding posed dewatering challenges.
Conservation & Biodiversity
We believe our commitment to environmental stewardship is not only a moral obligation, but also makes good business sense, and helps drive the success of our projects and operations company-wide. In addition to playing an integral role in the long-term growth of our company, protecting the environment is also important to our business partners and the communities in which our personnel (including our employees, independent contractors and other service providers) live and work. We want our neighbors to know that protection of the environment is a priority and we continuously evaluate and strive to reduce environmental risks, which can affect our business and the community. We have implemented system-wide programs to mitigate this risk and help ensure compliance with federal, state, and local rules and regulations.
We employ an avoidance approach in our construction process and, in our effort to minimize the impact of our operations, we seek to avoid sensitive areas, habitats, and seasons, when possible. In advance of project construction, we survey and assess our proposed route and/or sites to evaluate and identify the presence of threatened or endangered species, sensitive areas and habitats, high consequence areas, and areas of historical or cultural significance. Our approach to land use and biodiversity is governed by the principles of our Environmental policy, including our commitments to maintain efficient operations with a goal of using natural resources and energy more efficiently in the future, and to minimize disturbances from existing and future operations. In practice, our approach may involve:
· Extensive environmental surveying and permitting efforts,
· Co-locating pipelines within existing right-of-ways,
· Adjusting routes to avoid sensitive areas,
· Adjusting construction schedules to avoid sensitive seasons (such as mating seasons for threatened species),
· Safely drilling or boring under certain habitats and water bodies to minimize disturbances,
· Engagement with community and environmental stakeholders, and
· Engagement with agencies such as the U.S. Fish and Wildlife Service and U.S. Army Corps of Engineers.

We are committed to reducing the greenhouse gas (GHG) emissions intensity of our operations. We focus on reducing process, fugitive, and operational GHG emissions whenever possible. The main avenues to achieve emissions reduction across our system include:
- Capturing and liquefying vapors rather than flaring;
- Installing lower-emitting equipment when upgrading assets;
- Investing in technologically advanced control equipment; and
- Eliminating or minimizing waste streams.
Since 2011, Enterprise has experienced a historic period of growth primarily attributed to the development of U.S. shale resources and the renaissance of the U.S. petrochemical industry. From 2011 to 2019, the company put ~$28 billion of organic growth projects into service including 6 natural gas processing plants (totaling over 2.7bcf/d of capacity), over 5,000 miles of natural gas, NGL, crude oil and petrochemical pipelines, 7 NGL fractionators (with over 705 MBPD of capacity) and a world-scale propane dehydrogenation (“PDH”) facility. We also completed over $8 billion in acquisitions that added 7 marine docks at the Houston ship channel, over 20 million barrels of crude oil storage, 11 central gathering plants and 171 MBPD of condensate stabilization.
While substantially increasing our footprint and volumes handled by our assets, we focused on taking actions to reduce the partnership’s direct emissions intensity per barrel equivalent (BOE) through our integrated system. Our investments in midstream infrastructure over this period led to volume increases across our system. Total petrochemical facility volumes increased 65%, total NGL fractionation volumes increased 23%, total liquids pipeline volumes increased 65% and total fee-based processing volumes increased by 108%. This compares to growth of 17% in our direct emissions during this period, including emissions owned by our customers that are reported by our assets. As a result, our direct emissions intensity per BOE handled actually decreased by 19%.
- Reportable direct CO2 equivalent emissions with global warming potential ratios including: Subpart C – Emissions from Stationary Combustion Equipment (regardless of facility) & Subpart W – Emissions from Petroleum and Natural Gas Systems: all other equipment emissions from natural gas processing, transmission, storage. Also, includes emissions from gas gathering and boosting.
- New assets from acquisitions or construction impact total direct emissions, including: Oiltanking and EFS acquisitions, new pipelines, processing facilities, storage and export facilities.
- Total direct emissions increased 17% when compared to 2011.
Energy Use InitiativesWe believe operational efficiency is key to our ability to continue to provide critical infrastructure services in a sustainable and reliable manner. We are committed to using energy efficiently across our operations. We continuously review opportunities to improve our operational efficiency on existing and prospective assets, and rely on a diverse mix of energy sources, including solar and wind power. Examples of our use of efficient and/or renewable energy sources include:
