Tier II Reporting (EPCRA)

Program Overview

The Emergency Planning and Community Right-to-Know Act (EPCRA) of 1986 was created to help communities plan for chemical emergencies. It also requires industry to report on the storage, use and releases of hazardous substances to federal, state, and local governments.

What is EPCRA?

Please note: 

  • Montana does not collect fees for this submittal.
  • Montana does not accept hard copies.
  • Montana follows EPA requirements and does not have state-level requirements.

*EPCRA 302: Extremely Hazardous Chemical notifications

EPCRA 311: Requirement to provide MSDS for reportable chemicals

EPCRA 312: Hazardous chemical reporting

Filing Reports:

Beginning in late December 2013 Montana transitioned all Tier II report filing to E-Plan electronic submission. No hard copies or email submittals, please. Your report from 2013 should be in the system. See the directions below. You also have the option to attach contingency plans, maps, photos, etc. in the "additional information" section.

Regarding local filing, the decision to accept online reporting to LEPCs or TERCs and fire departments has been left up to individual jurisdictions.


Montana uses E-Plan for accepting online submission of Tier II chemical inventory information.

Facilities must submit their Tier II Report by logging into E-Plan's Online Tier II Reporting System web site at:

Eplan Logo (Click on icon to open E-Plan web site)
  1. Getting Started: Please use the button on any E-Plan website page to request for your login account (Access ID and password). In your request, please provide your facility name and address. Note: If you did not file a report in the filing year 2013, you will have to go to E-Plan's Online Tier II Reporting System Web Site at and click on. After you register, you will be assigned.
  2. Creating and Editing Report: You must the system in order to create and submit your data. After you sign in, you will be taken to the "E-Plan Online Filing Submission Management."
    • Entering New Facility Data: Under the "ENTER NEW DATA/RETRIEVE OLD DATA" section, choose 2014 for the filing year and press "Continue." Enter in your Facility Information. Press the "Save & Continue" button and then enter in your Facility Identification (NAICS required). Return to the 2014 Online Filing Home page by clicking the "Filing Management" link in the upper left-hand corner. From there, you will see the icon to Add New Chemical. Follow the prompts. When complete, return to the 2014 Online Filing Home page again, and press the icon to Add New Contact information.
    • Copying Data: Under the "COPY DATA" section, copy the data from 2013 to 2014 in the drop-down menu. Once this step is complete, you should see the years 2013 and 2014 listed under currently filed years in the left section. Select to retrieve Tier II data for 2014 in the drop down menu and press "Continue." You will be taken to the 2014 Online Filing Home page where you can edit your information if needed.
  3. Validating and uploading data into E-Plan: From the 2013 Online Filing Home page, press the Validate Record button at the bottom of the page. If any errors are found, they will be listed here, or it will indicate that the facility report passed all submission tests. Once the “Submission Report” indicates all required fields are correct, the “Upload Data to E-Plan” option will appear. Press the Upload Data to E-Plan button, select your facility, and press the Update button. The status should change from Not Filed to Filed when the report has been properly submitted. A confirmation message will be sent to the account’s email listed during the registration process, with a copy of your report attached in pdf format. Print and save these documents as proof of submission.

A facility's Tier II Report submittal will be deemed complete when the Montana Department of Environmental Quality can view its electronic submittal on E-Plan.

For E-Plan questions or requests, please use:

See E-Plan system updates below.

The choice of filing electronically or using a paper format only applies to local filings. You will need to contact the appropriate Local Emergency Planning Committee (LEPC -- there is one in each of Montana’s 56 counties) and fire department to see if they can accept electronic filings. If they can not accept electronic filings, a paper copy will need to be sent to the LEPC and fire department.

EPCRA 302 Notification: E-Plan allows the facilities to create and submit one time notification to SERC. Filing your 302 report via E-Plan meets your SERC requirement, but local LEPCs and Fire Departments may require a different submittal. Contact your County officials to see if they accept E-Plan as a form of electronic filing.

After your LEPC has determined who should have access, please go to and set up an account as a first responder. A request will be forwarded to DEQ for approval. Turnaround is usually a day or less. You will then receive notification from E-Plan about your login credentials. You may then access the Tier II reports.

New versions of ALOHA and CAMEO Chemicals are now available.

Note: If you're using the desktop version of CAMEO Chemicals 2.1 or later, you can use the automatic update feature to get the latest version. The next time* you start your desktop CAMEO Chemicals, it will notice that there is a new version available and give you the chance to auto update. If you say yes, the program will download and install the new version for you automatically. (If you have trouble with the automatic update feature, uninstall CAMEO Chemicals and then manually download and use the CAMEO Chemicals 2.4.2 installer from the link provided above.)

* The auto-updater checks once a day for updates. If you've already been using your CAMEO Chemicals program today, it may not alert you about the update until tomorrow. You can use the "Check for updates" item in the Help menu to check for updates immediately.

What's changed in ALOHA 5.4.5?

  • Updated chemical library, including new DIPPR chemical data and new Levels of Concern (AEGLs and ERPGs).
  • Added new RAILCAR source strength model for pressurized liquid tanks where a stationary cloud or "mist pool" is predicted to form. When RAILCAR predicts a mist pool will form, you have the option of running the RAILCAR model or the traditional ALOHA tank model to estimate the source strength values (i.e., release rate, duration, and amount). No additional inputs are required to run the portion of the RAILCAR model that is available in ALOHA. The RAILCAR model was developed by the Navy, based on the results of field tests that were performed to better estimate how ammonia and chlorine escape from transportation tanks that have been damaged.
  • Revised helps.
  • Made additional minor changes and bug fixes.

What's changed in CAMEO Chemicals 2.4.2?

  • Added DHS Chemical Facility Anti-Terrorism Standards (CFATS) to the regulatory information section on chemical datasheets and to the Advanced Search.
  • Added several new chemical datasheets to the database to have better coverage of all the chemicals in the CFATS list.
  • Updated Levels of Concern to the latest AEGLs and ERPGs.
  • Updated the EPA regulatory information to the 2015 List of Lists.
  • Updated Tychem(r) suit fabric information from DuPont.
  • Updated Hazardous Materials Table information shown on the UN/NA datasheets.
  • Updated list of ALOHA-selectable chemicals to match ALOHA 5.4.5.
  • Revised helps.
  • Made additional minor changes and bug fixes.

Want to know if your software is up to date?  The latest versions of the CAMEO software suite programs are ALOHA 5.4.5, CAMEO Chemicals 2.4.2, CAMEOfm 3.1 (or 3.1.1 for Mac), MARPLOT 5.0.1, and Tier2 Submit 2014.
