Who qualifies?

People who owned or occupied a residential property within one mile of the Koppers facility at 3900 S. Laramie Ave., Cicero, Illinois, at any time from August 6, 2019, through September 22, 2026. Renters can qualify as occupants; people who opt out are excluded.

How much could I receive?

A share of the $625,000 fund after approved deductions; no individual amount is set. The notice calculates shares by address, while the saved article describes equal shares per approved person. If multiple people claim for one address, ask class counsel how the payment will be divided.

Do I need proof documents?

Yes. Provide proof of identity and qualifying ownership or occupancy. The saved article lists government-issued photo ID, plus documents such as a deed, lease or utility bill. Submit the supporting documents with your completed claim.

Do I need a Claim ID or PIN?

The saved materials do not establish whether a settlement Claim ID or PIN is required online or by mail. The government-issued photo ID described in the documentation rules is a different requirement. For help, call class counsel at 1-800-536-0045.

What is the claim deadline?

December 7, 2026. Mailed claims and supporting documents must be postmarked by that date. The saved article also describes online filing by December 7, but no online cutoff time or time zone is stated.

How do I claim?

Submit the online claim described in the saved article, or complete, sign and date the paper form and mail it with supporting documents to Liddle Sheets P.C., Attn: Koppers Inc. Claim, 975 E. Jefferson Ave., Detroit, MI 48207. Keep a copy for your records.

When will payments be sent?

No payment date is set. The court must approve the settlement, claims must be reviewed and any appeals must be resolved. The final approval hearing is scheduled for January 19, 2027.

Will I receive money if I do nothing?

No. A valid, timely claim is required for payment. If the settlement becomes final and you have not opted out, you remain bound by the settlement even without filing a claim.

Does this settlement release personal-injury claims?

No, claims for medically diagnosed personal injuries are excluded from the release. The settlement otherwise covers specified property-related odor and emissions claims; it does not pay a separate personal-injury award.

How do I submit a claim for payment?

A claim must be mailed; the notice does not describe an online claim option. Keep a copy of the completed form for your records.

  • Complete, sign, and date the enclosed Claim Form.
  • Include the supporting documentation required by that form.
  • Mail the materials to Attn: Koppers Inc. Claim, Liddle Sheets P.C., 975 E. Jefferson Ave., Detroit, MI 48207. They must be postmarked by December 7, 2026.

What documents do I need to send with my Claim Form?

The notice requires supporting documentation, but it does not list the documents in the notice itself. It says the Claim Form identifies what must be included. Review that form carefully before mailing your claim.

Why can’t the notice tell me my payment amount now?

No fixed payment amount is promised. The money left after deductions from the $625,000 fund will be divided by the number of addresses for which claims were submitted. The notice says the amount cannot be known until claims have been submitted and reviewed.

When would payments be sent?

The notice does not give a payment date. The Court is scheduled to consider approval on January 19, 2027. If approval is granted, claims will be reviewed, and an appeal could cause further delay. Payment is not guaranteed unless the settlement is approved and any appeals are resolved.

What happens if I choose to opt out?

Leaving the settlement is also called opting out. If you opt out on time, you cannot receive settlement money or object to the settlement, but you will not be legally bound by the Settlement Agreement. The notice does not allow opt-outs by phone or email.

  • Mail a signed and dated exclusion letter by First Class U.S. mail by November 21, 2026.
  • Include your full name and the address of the property in the settlement area.
  • Use the exclusion statement specified in the notice and mail it to Class Counsel at the listed Detroit address.

What rights do I give up if I stay in the settlement?

If you stay in the settlement and it becomes final, you give up certain claims against Koppers and its affiliates concerning odors or emissions affecting property within one mile of the Facility during the covered period through the settlement’s Effective Date. This applies even if you do not file a claim. Claims for medically diagnosed personal injuries are not released.

Can I object to the settlement or speak at the Court hearing?

You may object only if you remain in the settlement; a person who opts out cannot object. You do not have to attend the hearing for the Court to consider a timely written objection.

  • Send a written comment or objection to Class Counsel by November 21, 2026.
  • Include the required identifying and property information, your signature, and a detailed explanation of your comment or objection with supporting documents.
  • To speak at the hearing, say in that same letter that you intend to appear and speak.
