The Surface Technology Environmental Resource Center (STERC) provides a wealth of useful environmental compliance information to the surface finishing and surface treatment industry.

This website was developed by the National Center for Manufacturing Sciences in partnership with the metal finishing industry. Funding for this project has been provided by US EPA under the National Compliance Assistance Centers program. For compliance assistance questions, or to pass along suggestions, please use Ask STERC. Our Compliance Assistance Team will respond as quickly as possible.


The highly acclaimed Hard Chrome Plating Training Course is now available at no cost on STERC.
