Other environmental documents prepared by the Wastewater Treatment Division, such as documents prepared under the National Environmental Policy Act (NEPA), may also be listed.

Local, state and federal regulations mandate the ways in which agencies must notify the public that environmental documents are available for public comment. These may include mailings, signs and/or newspaper notices. The Wastewater Treatment Division typically makes the documents available in local libraries and upon request.
