Maryland Online Tier II Reporting System (MOTTRS)


All Maryland Tier Two Reports must be completed using MOTTRS.

MDE has implemented an online reporting system for facilities to use for reporting their Tier II Emergency and Hazardous Chemical Inventory Reports.  These reports, required by Section 312 of the federal Emergency Planning and Community Right-to-Know Act (EPCRA), require covered facilities to provide detailed reports about the hazardous materials they use or store on site.  The reports are submitted to the State Emergency Response Commission (SERC), the Local Emergency Planning Committee (LEPC) with jurisdiction over the facility, and the local fire department that would respond to any emergency at the facility.  Reports are due March 1st of each year.  MDE is the designated repository for the SERC copy of the reports.

In October 2014 MDE is introducing a new and improved MOTTRS. The new application uses the Tier2Manager by IDSI and has a host of features that simplify and streamline the reporting process. If you already have a MOTTRS account you can access use your existing username and password to access your data. Prior year submissions have been migrated to the new system.

The browser requirements for the all new MOTTRS are:

Internet Explorer 10 (non-compatibility mode) or higher;
Firefox 20 or higher;
Chrome 26 or higher.

Using older versions may create problems!  You will need Adobe Acrobat Reader to use this system.
You will need to enable javascript and turn off the pop-up blocker in your browser.
