Illinois medical waste rules at a glance
| Governing agency | Illinois Environmental Protection Agency (IEPA), Bureau of Land |
|---|---|
| Primary statute / rule |
|
| Generator registration | Illinois does not require a standalone PIMW generator registration or license. Generators must comply with the packaging, labeling, storage, manifesting, and treatment-or-disposal standards of 35 Ill. Adm. Code Parts 1420, 1421, and 1422, and a generator who has its PIMW hauled off-site carries a manifest tracking obligation rather than a registration. [source] |
| On-site storage time limit | PIMW must not be stored for more than 72 hours unless the surface temperature of the package is held at or below 45 degrees Fahrenheit, and in no case for more than 30 days regardless of temperature, unless the Illinois EPA authorizes otherwise in a permit (35 Ill. Adm. Code 1422.111). [source] |
| Approved treatment methods |
|
| Transport / manifest rules | PIMW transported off-site may be hauled only by a transporter holding an Illinois EPA PIMW hauling permit, unless exempt (such as a generator hauling solely its own waste, a noncommercial load under 50 pounds, or the U.S. Postal Service). Each pickup must be accompanied by a four-part PIMW manifest tracking the generator, hauler, and destination facility, with the original returned to the generator within 35 days and all copies kept for three years. PIMW must not be in transport for more than 10 calendar days. [source] |
| On-site treatment allowed? | Yes. A person conducting a treatment, storage, or transfer operation for PIMW generated by that person's own activities, handled within the site where it is generated, does not require a permit, but must still meet the on-site storage, packaging, and treatment-efficacy standards of Parts 1421 and 1422. [source] |
| Penalty range | Civil penalty not to exceed $100,000 for the violation, plus an additional civil penalty not to exceed $25,000 for each day the violation continues, under 415 ILCS 5/42(a). Knowing violations are a Class A misdemeanor under 415 ILCS 5/44 and may carry forfeiture of profits and of any vehicle used in the violation. [source] |
What is unique about Illinois
Illinois regulates medical waste under its own statutory term, Potentially Infectious Medical Waste (PIMW), defined in 35 Ill. Adm. Code 1420.102, rather than the federal-era "regulated medical waste" label. The program sits in the Environmental Protection Act (415 ILCS 5, Title XV) and the Pollution Control Board rules at Subtitle M, administered by the Illinois EPA Bureau of Land. A distinctive feature is the tiered storage clock: 72 hours at ambient temperature, extendable only if the package surface is kept at or below 45 degrees Fahrenheit, and a hard 30-day ceiling regardless of refrigeration (35 Ill. Adm. Code 1422.111).
Frequently asked questions
Which agency regulates medical waste in Illinois?
The Illinois Environmental Protection Agency (Illinois EPA), Bureau of Land, regulates Potentially Infectious Medical Waste under the Environmental Protection Act (415 ILCS 5, Title XV) and the Pollution Control Board rules in 35 Ill. Adm. Code Subtitle M (Parts 1420, 1421, 1422).
How long can PIMW be stored in Illinois?
PIMW may not be stored for more than 72 hours unless the package surface temperature is held at or below 45 degrees Fahrenheit, and in no case longer than 30 days regardless of temperature, unless the Illinois EPA authorizes otherwise in a permit (35 Ill. Adm. Code 1422.111).
Do I need a permit to transport my own PIMW in Illinois?
No. A person transporting PIMW generated solely by that person's own activities is exempt from the PIMW hauling permit, as are noncommercial loads under 50 pounds and the U.S. Postal Service. Commercial haulers carrying another party's PIMW must hold an Illinois EPA PIMW hauling permit and carry a manifest for each pickup.
Can a generator treat PIMW on-site in Illinois?
Yes. A treatment, storage, or transfer operation for PIMW generated by the operator's own activities and handled within the site where it is generated does not require a permit, but it must still meet the on-site storage and treatment-efficacy standards in 35 Ill. Adm. Code Parts 1421 and 1422, including demonstrated elimination of infectious potential.
