The WHOPRS website has a standard maintenance window on Wednesday mornings from 6:00 a.m. through 8:00 a.m. central time. If you are logged into the system during an active update, you will be logged out and you will lose any unsaved work.

The Wisconsin Hazmat Online Planning and Reporting System (WHOPRS) can be accessed here: . Please note that this is the same URL that facilities have used. If you are a hazmat team, fire department, or county user, please change your saved bookmarks to the new URL.

The WHOPRS system was upgraded to a new platform in August 2017. The new platform is a change from the older system and users are encouraged to view the new training videos listed below. The system upgrade will include the new mandatory EPA reporting requirements described below.

Things to Know About Submitting a Report

  • For a facility to meet their yearly Tier II reporting requirement, they must choose the “Annual” report type.
  • Make sure each submission is certified after you submit. If it says it is “Initiated”, then it has not been certified and is incomplete. To certify the report, click on the name of the facility from your Active Facilities (Facilities tab) list. In the Regulatory Reports section, click on the initiated report in blue.
  • You should now go to the last step and click “Continue” to certify the report.
  • If you owe a fee and you pay by credit card, you should receive a confirmation of payment email.
  • If you have a question or issue regarding a submission in WHOPRS, please see the “Click here for WHOPRS Help Desk”, in the upper right corner. If you have an EPCRA program question, please call us. We are happy to help! (see EPCRA Contacts for our numbers)
