JULY 2017

NEW TIER II CHEMICAL PHYSICAL AND HEALTH RISK CATEGORIES have been updated in Tier II Manager and a list is included in the Resource Links below.  All 302 EHS and 311 SDS submissions, as well as 312 Tier II Update (current calendar year) submissions, will contain the new categories.  An updated SDS must be attached to each chemical entry in Tier II ManagerTM.  Contact chemical suppliers for SDSs with new physical and health risks.

Facilities are encouraged to submit 2017 Tier II UPDATE (current calendar year) reports in order to prepare for the upcoming reporting year.  Update reports may be submitted through December 15, 2017.  Update information will roll forward for 2017 ANNUAL Tier II report editing.  2017 ANNUAL Tier II reports are due between January 1 and March 1, 2018.  Submitting update reports now will allow for a smoother transition into the upcoming reporting year.


Owners or operators of facilities with hazardous chemicals on hand in quantities equal to or greater than set threshold levels must submit Tier II forms between January 1 and March 1 for the previous calendar year.​

The purpose of the Tier II form is to provide state and local officials and the public with specific information on hazardous chemicals present at your facility during the previous calendar year. 

The Illinois Emergency Management Agency (IEMA) requires all regulated facilities to submit 312 (Tier II) information electronically by using Tier II Manager™, IEMA's online filing system.  Each facility's username is unique to its physical (9-1-1) address. 

IEMA also requires all 302 (EHS) and 311 (MSDS) submissions be made through Tier II Manager™.  Print out completed 302 and 311 reports, sign and submit to the LEPC and fire department.  LEPC and fire department contact information is located in the upper right side of this webpage.  DO NOT SUBMIT HARD COPIES TO IEMA.  HARD COPIES ARE NOT ACCEPTED AND WILL BE SHREDDED.

2016 IS THE CURRENT TIER II REPORTING YEAR.  2016 facility submission instructions are in the Tier II Manager™ Sidebar Resources Section.  The Sidebar button is a green question mark located on the right side of each Tier II Manager Screen.  Facility submission instructions are also available in the Resource Links below.​

SYSTEM​ REQUIREMENTS for the Tier II Manager™ Online Reporting System:

  • Mu​st use Internet Explorer 11 (non-compatibility mode) or higher, Firefox 20 or higher, or Chrome 26 or higher. Using older versions may create problems.  

  • Mac users, with Safari, can use Chrome or Firefox versions listed above.

  • Need Adobe Acrobat Reader to use this system.  Download the Adobe Reader​

  • Need to enable JavaScript and turn off the pop-up blocker in your browser. 

  • If any problems, contact your technology desk to verify whether you have these requirements.

Site plans must meet minimum requirements.  In Tier II Manager, a site plan is a one-page diagram of where the Tier II chemicals are stored within the facility's site/location. An up-to-date site plan (map) may be attached in Step 5 on the Facility’s Home Page.  Site map requirements, and sample site maps, are listed in the Resource Link Section below.

Electronic Safety Data Sheets (SDSs) must be attached to current (2016) Tier II chemicals in the Tier II Manager Chemical Section (Step 2 of filing process).  Electronic SDSs may be obtained from your chemical wholesaler or manufacturer. Tier II Manager will accept PDF files no larger than 5 MB. If there are multiple SDSs for one chemical entry, and the SDSs contain the same physical hazards and health effects, attach the SDS that contains the highest percentage of that chemical.  In other words, the worst-case scenario SDS should be attached.

Facilities that reported in 2015 may use their username and password information to access Tier II ManagerTM (see link below).  Enter the Username and Password on the Login screen.  The latest submitted report’s information will be brought forward for 2016 Tier II ANNUAL report editing.  Pay close attention to chemical and contact information as these are the two sections that most-often require editing.

If you don't remember your username and password, please send a request to Include your facility name and physical address in request.  Due to security concerns, if a consultant requests a username/password on behalf of their client facility, IEMA must receive the request from a FACILITY representative using a facility-related e-mail address.  The facility representative may "cc" the consultant in the request and ask that IEMA "reply to all" when responding.

Facilities that reported in 2015 but are not subject to reporting for 2016 should make the facility inactive in Tier II Manager or contact IEMA at

Facilities that didn't file in 2015 but are subject to reporting for 2016 should contact IEMA, at for a state-issued username and password.  In order to set up a user profile, please include the facility name, physical address, city and zip code, as well as a facility representative's name, telephone number, and e-mail address.

Facilities that have moved to a new location in 2016 should contact IEMA, at for a NEW state-issued username and password.  DO NOT change the address assigned to your username.  In order to set up a new user profile, please include the facility name, physical address, city and zip code, as well as a facility representative's name, telephone number and e-mail address.  Note in the e-mail that the facility relocated in 2016.

After you have completed your 2016 ANNUAL Tier II submission, PRINT out hard copies, sign at the bottom of Page 1, and submit to your LEPC and fire department (links in upper right corner of this webpage).  DO NOT SUBMIT HARD COPIES TO IEMA.  HARD COPIES ARE NOT ACCEPTED AND WILL BE SHREDDED.  

Inquiries should be made to Ms. Carlita D. Crockett or Ms. Lori Canterbury, IEMA Tier 2 Specialists, at 217-558-0559 or​
