Tier II Hazardous Material Reporting in Wisconsin | When Are Tier 2 Reports Due?

EPCRA 302/311/312 reports (“Tier II Reports”) are due on an annual basis to the State and Local Emergency Planning Committee and local emergency response agencies, such as the fire department. The information provided is used in the evident of an emergency, such as a fire, to evaluate potential chemical and other hazards at the property, and to select appropriate protection equipment and fire fighting techniques. EPCRA reporting facilities disclose the types, quantities and locations of hazardous materials. Facilities also provide with Safety Data Sheets for each material.

There are separate reporting requirement for hazardous materials (any material that requires a Safety Data Sheet under OSHA rules) and Extremely Hazardous Substances (EHS) which are a specific chemicals listed by US EPA. A very common example of one such EHS is sulfuric acid.

When are Tier II reports due in Wisconsin?

The Tier 2 report is due March 1 of each year and is based on chemicals stored at your site during the previous calendar year. Reporting can be completed by using the Wisconsin Hazmat Online Planning and Reporting System.

MPCA Delays Enforcement Action On Handling of Hazardous Aerosols & Cylinders

The Minnesota Pollution Control Agency has extended its compliance deadline for one important change to its policies regarding management of spent aerosol cans and gas cylinders that contain hazardous chemicals. Historically, the MPCA had elected not to take enforcement action against hazardous waste generators who empty aerosol cans and cylinders by releasing pressure into the atmosphere, including those who puncture cans with equipment fitted with carbon or other filtration systems to capture vapors. The agency considers this "abandonment" of hazardous waste, which is prohibited.


The MPCA had planned to change its enforcement policy as of January 1, 2017. which would require generators using such equipment to find an alternate means of handling aerosol cans and cylinders. The agency recently announced that it has extended this change to enforcement policy until January 1, 2018, to allow facilities more time to modify their practices, if needed.


Minnesota is one of only a few States that allows aerosol cans and gas cylinders to be handled as though they were universal wastes, although they are technically not regulated as universal wastes under State and Federal rules. MPCA has established some minimum requirements generators must comply with to take advantage of this policy.
