Tier2 Reporting Requirements


Section 312 of Title III requires that the owner or operator of a facility submit their Tier Two form if so requested by a State emergency response commission, a local emergency planning committee, or a fire department with jurisdiction over the facility.

This request may apply to the owner or operator of any facility that is required, under regulations implementing the Occupational Safety and Health Act of 1970, to prepare or have available a Material Safety Data Sheet (MSDS) for a hazardous chemical present at the facility.  MSDS requirements are specified in the Occupational Safety and Health Administration (OSHA) Hazard Communication Standard, found in Title 29 of the Code of Federal Regulations at x1910.1200.

This form does not have to be submitted if all of the chemicals located at your facility are excluded under Section 311(e) of Title III.

All reports are due by March 1st of each year.


For Reporting Year 2013 (RY2013) the EPA made several changes to the Tier2 form: 

  • Added new Manned/Unmanned facility checkboxes
  • Added "Dun and Bradstreet Number (Parent Company)" field (only available when Parent Company is chosen as a Contact Type)
  • Added "Confidential" checkbox for chemical storage locations
  • Added Maximum Code range field (for maximum daily amount of chemical onsite) for mixture components
  • Added "Maximum No. of Occupants" field
  • Removed "Number of Employees on Site" field
  • Removed latitude/longitude method and description fields
  • Switched to using new 2013 range code values for Maximum and Average Daily Amounts of chemicals onsite
  • Switched to using full descriptive phrases (rather than codes) for container type, pressure, and temperature

Tier2 Instruction 


In an effort to streamline the yearly Tier II reporting process, the State Emergency Response Commission now requires the use of the web-based program E-Plan for all Tier 2 submittals. As of March 2, 2012, hard copy or Tier 2 Submit files are no longer accepted .

For RY2013, E-PLAN will continue be used for Tier 2 Submittals.

More information on E-PLAN can be found below or on the Mississippi Emergency Response Agency Tier 2 Website

What is E-Plan?


E-Plan is the nation’s largest database of chemical and facility hazards, with over 300,000 Tier II and 17,500 RMP facilities from across the nation in one database. E-Plan was developed by the U.S. EPA Office of Emergency Management in collaboration with The University of Texas at Dallas. It is a means of collecting chemical facility reporting information and addressing federal regulations regarding chemicals in the community.

By utilizing the E-Plan system, the workload required by regulated facilities to submit Tier II information can be greatly reduced. A single submission of Tier II information to E-Plan can satisfy the requirements for individual submissions to the SERC, LEPC and local jurisdictional fire departments. Regulated facilities no longer have to deal with the issue of sending files or hard copies to all agencies. The regulated facility can view their Tier II information at any time on E-Plan and, as necessary, make up-to-the-minute changes to their Tier II information on-line. Since the 2009 year reporting period, the SERC has been uploading all Tier II information to E-Plan, so many of the Mississippi facilities are already pre-populated in E-Plan.

How to Become an E-Plan User:


If you are a facility submitting Tier II information, the process is simple and involves just a few minutes of your time. Go to erplan.net/eplan/onlinefiling/filingLogin.htm, and click on the link to “Register Now” to begin the process. You will be asked to create a password and enter the submitter’s name and e-mail address. You will then be assigned an Access ID number, which is a unique identifier for your facility. You will then be taken to the “E-Plan Online Filing Submission Management” page where you will need to either Enter new Data for your facility or upload your Tier2, .zip, t2s or CAMEO .zip file from the previous year into the system.

If you are a state, local authority, or first responder wanting to access E-Plan facility information, go to https://erplan.net/eplan/user/accountSignup.htm and follow the registration steps under the “First Responders” section. Enter in the information as an Account Type is USER.

As a part of completing the registration, you will be asked to select an Authorizing Authority. The Authorizing Authority is someone from your state or county that has been tasked with ensuring you are an individual that has a need to be an E-Plan user. The certification may take up to one week. Following your approval by the Certifying Official, you will receive a confirmation e-mail from the E-Plan Administrative Team that will include your user name and password. Please reference the Authorizing Authority .pdf document.

That’s it. If you are a first responder, you can begin using the information in E-Plan to ensure your responders are fully knowledgeable of the hazards posed by the chemicals in a facility within their jurisdiction.

To assist you in understanding E-Plan and its available functions, there are a number of tutorials available. Links to these tutorials can be found on the E-Plan Home Page, or directly at: eplannews.utdallas.edu/Training.htm. Please review the attached instruction page for more information.
