E-Permitting Portal Electronic Signatures

The Department of Health (DOH), Environmental Health Administration (EHA) e-Permitting Portal received Cross-Media Electronic Reporting (CROMERR) certification by the Environmental Protection Agency (EPA) for Electronic Signature. This allows applicants to submit electronically through the EHA e-Permitting Portal without the need to physically send in an ink signature and CD/DVD. EHA Electronic Signature Forms may only be submitted by an account with electronic signature rights. For more information see:
