For workers and families

Did You or a Loved One Work at the Plant?

Workers who got sick — and their families — may qualify for federal money and medical care. This isn’t a rumor. The Claymont plant is on the government’s own list.

The plant went by many names

If any of these sound familiar from your family’s work history, keep reading:

Allied Chemical and Dye Corp.
Allied Chemical / Allied-Signal
General Chemical
Union Texas Petroleum Division
Honeywell / Delaware Valley Works (“DVW”)
Chemtrade

All the same place: 6300 Philadelphia Pike, Claymont.

Who may qualify

People who worked there in the early 1950s to late 1960s — the years uranium was handled for the government.
People who worked there up to 1977 — the government says leftover radiation may have stayed after the uranium work ended. Workers for the later owners count too.
Survivors. If the worker has passed away, a spouse or children may claim in their place.

The illness matters most for cancer. If you or your loved one worked there and later got cancer, it is worth asking.

What you could get

The federal program (called EEOICPA) can pay $150,000. It also covers the medical costs for the illness. Survivors can claim too. Delaware workers and families have already received over $8.6 million through this program.

The honest catch

Not every claim is approved. For cancer, the government estimates how much radiation the worker got. If radiation was at least as likely as not the cause, the claim is paid.

Here’s the problem: records show Claymont workers never got radiation badges. So the government guesses, using numbers from other plants.

Outside experts re-checked one Claymont case. They found the worker’s dose could be far higher than the first estimate — high enough that a past “no” may not be the end of the road.

CC4EJ can sit with you

Paperwork is easier with a neighbor beside you. We can help gather work history. We can sit with you on the call. We can connect you with other worker families. Check the worker box on the petition, or reach us at roby@cc4ej.org or 302-360-1118.

Your story is the proof

The government admits it doesn’t know where on the site the uranium work happened. The contracts are lost. That means worker memories are the record. Even if you never file a claim, your story helps every neighbor. Please share it with us.

Where these facts come from

U.S. Department of Labor facility sheet: Allied Chemical and Dye Corp., North Claymont, DE — Atomic Weapons Employer (the government’s label for plants that handled uranium for the weapons program), early 1950s–late 1960s; residual radiation (leftover radiation) late 1960s–1977; later owners’ employees covered. (DOL mailed this sheet to Claymont homes in 2018.)
U.S. Department of Labor, Energy Workers program (dol.gov): Part B benefits — $150,000 lump sum plus medical costs; Resource Center 1-866-888-3322; online filing at eclaimant.dol.gov.
DOL program statistics for Delaware (February 2025): over $8.6 million paid to Delaware claimants under Parts B and E.
Independent review (SC&A, 2014, for the federal Advisory Board): a Claymont worker’s dose re-checked at several times the first estimate. Draft advisory documents.
NIOSH (the federal worker-health agency) evaluation: “potential for significant residual contamination” — leftover radiation — at this site, late 1960s–1977; no radiation survey records from the plant’s working years.
