  • Environmental Stewardship
  • 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. 


    Environmental Policy

    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.

      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.

      Emission Reductions

      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 Initiatives

      We 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:

      Solar Energy
      We have over 16,200 metering stations across the United States operating on solar power. These stations generate approximately 7 megawatt hours of power generation per day. These solar operated stations run natural gas chromatographs, measurement, controls, and communications equipment. Enterprise also utilizes solar units to generate power to certain cathodic protection system installations for the purpose of corrosion prevention across our liquid and gas pipelines. Power generation at the point of power consumption eliminates the inefficiencies and environmental footprint of conventional electrical transmission and distribution systems. Solar powered stations also save resources by eliminating the need for chemically treated electric poles and high capacity wiring which benefits property owners by minimizing the electrical infrastructure needed across their land.

      In certain areas of operations where wind is an attractive power source, Enterprise utilizes wind turbines to generate power for cathodic protection systems for the purpose of corrosion prevention across our liquid and gas pipelines.

      ERCOT Demand Response Program
      Enterprise participates in a program established by the Electric Reliability Council of Texas (ERCOT) designed to preserve the reliability of the electric grid, and mitigate the negative implications of surges in electricity demand during peak hours. At certain locations, Enterprise has the ability to act as a “Load Resource” by temporarily modifying our operations to reduce our power usage during periods of peak grid consumption. This contributes to greater operational efficiency in the electric markets, and lessens the need for incremental power generation facilities to accommodate surges in electric demand. As described by ERCOT, “the value of a Load Resource’s load reduction is equal to that of an increase in generation by a generating plant.[1]” ERCOT’s Demand Response program is increasingly important as the grid becomes more reliant upon intermittent renewable resources. Through collaboration with internal and external stakeholders, we are able to contribute to the reliability of the Texas electric grid and the efficient use of resources.  http://www.ercot.org/services/programs/load/laar

      Renewable Energy Initiative
      In addition to Enterprise-installed power generation sources described above, we purchase power generated by wind and solar sources. In 2019, we estimate that approximately 18% and 17% of our electricity usage in Texas and company-wide, respectively, was attributable to wind and solar power generation sources. In 2020, we launched a new initiative to evaluate opportunities for expanded solar power purchasing and/or installations across our systems. We believe this initiative will help further our goal to use natural resources more efficiently in the future.

      CO2e Sequestration Initiatives
      Enterprise currently sequesters approximately 35,000 metric tons per year of carbon dioxide in geologic storage. The 2018 expansion of the federal Section 45Q tax credit may support additional opportunities to sequester or beneficially reuse carbon dioxide that is produced as a byproduct of some of our operations. We do not currently claim a credit under Section 45Q, but we are evaluating Section 45Q and the Department of the Treasury’s recent guidance and proposed regulations with a view to whether the expanded tax credit will support operational changes and/or commercial agreements that would add financial value for our limited partners while also reducing our carbon footprint.
