Right to Know

Pursuant to State and Federal laws, information collected under the Emergency Planning and Community Right-to-Know (RTK) Act is considered public information and is accessible to the public.

This allows citizens who live near facilities with chemicals to be aware of any potential risk and learn what they may need to do in the event of a chemical release.

There are two exceptions. Under federal law, trade secrets are not allowed to be released. Under State law transportation information is considered confidential and may be released only to those who need it for planning purposes.

The SERC embraces the community right-to-know requirements. We encourages citizens to use this information as part of developing family emergency plans for all hazards.

You may request information using the downloadable form or our online form at the bottom of this page. We will respond to your request as soon as possible.

This form may be used to request hazardous materials information available under the Emergency Planning and Emergency Right to Know Act (EPCRA):
