EHCMA’s voluntary alliance of more than 130 chemical manufacturers, refiners and supporting distribution facilities work together for the safety, environmental and economic well being of their plants and communities.

Making Good Everyday
Our association is dedicated to sharing best practices in safety, the environment, and communication, as well as providing our communities with well-paying jobs, a higher standard of living and sustainable environmental initiatives that will strengthen our region and enrich the lives of residents.

We’d like to invite companies involved in industry and manufacturing in the East Harris County area to become a part of our growing organization. Join us as we continue our dialogue on the values and benefits industry brings to the community and to people throughout the world.
