Dow in Louisiana

What do disposable diapers, electronic components, football helmets and automotive parts have in common? They are all made from the basic and specialty chemicals produced by the Louisiana employees of The Dow Chemical Company.

Dow's operations in Louisiana began in 1956 with the purchase of four plantations in Iberville and West Baton Rouge parishes.

Today, Dow Louisiana is the largest petrochemical company in the state, providing jobs for more than 6,000 Dow and contract employees, and pumping over $1 billion into the state’s economy each year. At six locations, we manufacture more than 100 basic and specialty chemicals that are shipped worldwide.

These products serve as building blocks for hundreds of everyday products from plastics to soaps, detergents, food additives, cosmetics, shampoos and pharmaceuticals.

In each of our locations, Dow is a part of the surrounding community, providing jobs, economic stability, and striving to maintain and enhance the quality of life. Committed to the principles of sustainable development, Dow and its employees in Louisiana seek to balance economic, environmental and social responsibility as we invest in our communities and encourage them to invest in themselves.



At four sites in Louisiana – Plaquemine, Grand Bayou, Hahnville, and Greensburg, – Dow manufactures more than 100 basic and specialty chemicals that are shipped worldwide.

  • Louisiana Operations near Plaquemine is one of the largest petrochemical facilities in Louisiana. Home to most of Dow’s global businesses, the 3000-acre integrated manufacturing site produces more than 50 different basic and specialty chemical products.

  • Dow subsidiary Amerchol operates a 50-acre site with two production units in Greensburg, manufacturing a wide variety of ingredients for the personal care and topical pharmaceuticals industries. Amerchol products are used in skin and hair-care products, makeup and toiletries.

Locations - Louisiana Operations

Dow came to Louisiana in 1956, drawn by the state’s abundant natural resources, excellent transportation network, deep water port, easy access to the Mississippi River, dedicated workforce and available land.

With the purchase of four plantations in Iberville and West Baton Rouge parishes, Dow established Louisiana Operations - its first site in the state.

Today, the 1,500-acre integrated manufacturing facility near Plaquemine and brine operations in Grand Bayou comprise one of Louisiana’s largest petrochemical facilities. With more than 3,000 employees and contract employees, Louisiana Operations is the largest employer in Iberville and West Baton Rouge parishes and plays an active role in the surrounding communities.

Home to most of Dow’s global businesses, Louisiana Operations has 23 production units manufacturing more than 50 different intermediate and specialty chemical products, such as chlorine and polyethylene, that are used to produce cosmetics, detergents, solvents, pharmaceuticals, adhesives, plastics for a variety of packaging, automotive parts, electronics components, and more.

With an industrial park design, Louisiana Operations has co-located companies within the site’s borders.  It offers convenient transportation options, including marine, rail, truck and pipeline.  In addition, Louisiana Operations has tremendous power and steam capacity along with the ability to treat its own waste.

Contributing to Community Success

As part of its global commitment to sustainability, Dow looks to invest in programs and organizations that will have a long-term impact and serve as a starting point for widespread community involvement and growth. The list of organizations, projects, programs, events and activities that Dow sponsors or is involved with in Louisiana is extensive, but most can be categorized into three areas of focus: economy & workforce development, science, mathematics, engineering and technology related education, and protection of the environment.

Dow’s innovative Community Success process allows strategic Dow communities to provide qualitative and quantitative inputs on their quality of life issues and what Dow’s appropriate role is – whether it’s directly addressing community needs or using its leadership position to influence other organizations. Through this process, Dow is able to better align the community’s needs with Dow’s intellectual and business knowledge-how to maximize the long-term benefit to the community.



Case for Change

Louisiana Operations implemented a new Community Advisory Panel (CAP) in the Summer of 2011. LAO operated under its original CAP charter since 1989 and based on extremely positive (>75%) familiarity and favorability ratings, we were given "permission" from our community to lead, stimulate, innovate and serve as a catalyst for change. Dow uses CAP meetings to meet with high level leaders in the community that have influence and can offer input to how Dow can proactively lead instead of being a "fast follower" and to exceed community expectations instead of just satisfying them. Focus is given to EH&S, Dow business strategy and LAO business/community affairs. The membership of this CAP is key business, community and political leaders from Iberville and West Baton Rouge Parishes.


  • Establish a "Dow-knowledgeable" panel of leaders from the surrounding community, external to LAO
  • Open and foster two-way communication with the panel
  • Identify where can Dow have the greatest impact and exercise the most focused leadership and responsibility


Membership is by invitation only and is restricted to the following individuals. A member of the executive staff of any CAP member may attend in place of an unavailable CAP member.

Invitation to membership is extended by letter from LAO Site Leader, Eduardo Do Val, to individuals holding the office, title, or role listed below. The letter of invitation provides an overview of the content of this guiding document and also includes a 1 year meeting schedule in order to obtain commitments from the onset.

  • Iberville Parish President — Mitchell Ourso
  • West Baton Rouge Parish President — Riley "Pee Wee" Berthelot, Jr.
  • Iberville Parish Council Chair — Matt Jewel
  • West Baton Rouge Parish Council Chair — Carey Denstel
  • Iberville Parish School Superintendent — Dr. Arthur Joffrion

Fight the Flood

Beginning on Thursday, August 11th communities in South Louisiana prepared for what seemed to be a normal summer storm only to soon find out it was something very different. Rainfall began Thursday and continued for two full days. This unprecedented “no-name storm” left the southern Louisiana communities devastated. Many areas received more than two feet of rain over a 48-hour period.

Although this storm left an immediate impact on the community and the lives of many Dow employees, it gave us the opportunity to see the true spirit of Dow. Many employee’s answered the call for help by rescuing trapped citizens, volunteering at shelters and donation centers, helping with beginning stages of restoration, and a host of other flood recovery activities.

166 Dow employees were directly impacted by the catastrophic flooding. The water may have receded but the devastation remains. Impacted employees are now left to assess the damage and attempt to start completely over. In true Team Dow spirit our employees jumped into action to help their fellow colleagues without question. It has been clear that the support from Team Dow has helped many of these employees in such a trying time.

As restoration continues employees from Dow sites across Louisiana continue to volunteer side by side in assisting our region in recovery efforts. Stage two of recovery has begun and our employees still need more help. Through Employees 1st, an affiliate of the Baton Rouge Area Foundation, Dow has established a relief fund for Dow colleagues to make charitable contributions that will go directly to Dow employees in Louisiana who have been impacted with unexpected difficulties that require financial assistance. Your donations are greatly appreciated and will make a difference in a co-workers life, especially during a time of need. If you feel called to give, please consider donating to The Dow in Louisiana Employee Assistance Fund.


What do we mean when we say "flares"?
Flares are safety devices that are used at many petrochemical facilities to effectively burn industrial gases that cannot be returned to the process. Burning converts the gases into two common substances: carbon dioxide and water vapor.

The flare is an essential safety device that is designed:

  • To protect our community and employees from exposure to pollutants
  • To protect equipment from catastrophic failure (pressure relief)
  • With safety front of mind: Flares are big enough to handle the largest release

What do you see when you notice a flare? At Dow, we aim to minimize the impact to the community when we operate our safety devices. If you are near the plant during flaring activity, you may notice:

  • Light – Besides the flame itself, you will notice an orange glow surrounding the flame as well.
  • Smoke – Only when necessary, smoke may be visible from the flare. This occurs at instances when there is a loss of steam to the tip of the flare due to a power interruption.
  • Noise – The gases are mixed with steam and air at high volumes and velocities which cause an audible rumbling sound.

What's going on when you see a burning flare?
The flares are a permitted air pollution control device used as an outlet to burn excess gas during normal operations, maintenance activities, and partial or complete production unit startup and shutdown. In these scenarios, equipment and piping can become over-pressured. Then, the excess gas is released through pressure relief valves and sent to the flare stack through piping. The burning of the flare ensures the continued safe operations of the plant under all conditions.
