Aliquippa Forge

(Site Profile/Docket Number 040)

Location: Aliquippa, Pennsylvania

Also Known As: Vulcan Crucible Steel Co., Universal Cyclops, Inc.

The Special Exposure Cohort (SEC) is a unique category of employees established by the Act (42 CFR Part 83). Claims compensated under the SEC do not have to go through the dose reconstruction process. To qualify for compensation under the SEC, a covered employee must meet specific requirements (e.g., must have at least one of 22 “specified cancers,” and have worked for a specified time period at one of the SEC sites). Classes of employees and work sites can be considered for addition to the SEC through a NIOSH petition process. More information about the Special Exposure Cohort can be found on our Frequently Asked Questions page.

Open/Active SEC Petitions

To date, there are no open/active SEC petitions from Aliquippa Forge.

Technical Documents

If the energy employee’s personal radiation information is incomplete, NIOSH will use other sources to estimate the radiation dose. This may involve using technical documents called Site Profiles, Technical Basis Documents, and Technical Information Bulletins.

Program Evaluation Plans (PEPs) and Program Evaluation Reports (PERs)

NIOSH is committed to applying the best available science in dose reconstructions. In keeping with this commitment, completed cases with probabilities of causation less than 50% are reviewed as relevant new information becomes available. The results of these reviews are described in a Program Evaluation Report (PER). The PER details the effect, if any, of the new information on the completed dose reconstruction. If it appears that the new information may result in an increase in dose for a completed dose reconstruction with a probability of causation of less than 50%, NIOSH is committed to working with the Department of Labor to reopen and rework the dose reconstruction, as appropriate. A Program Evaluation Plan (PEP) describes plans for evaluating specific program details or issues.

To view all PERs and PEPs that have been developed, please refer to the Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs) page.

    February 15, 2017

    About this Document: Determines the effect of the revision to ORAUT-TKBS-0021, (Aliquippa Forge) on previously completed claims.

    Summary: A new dose estimate was performed for 21 claims using revision 2 of the TBD, as well as all other applicable approved dose reconstruction methods. The resulting probability of causation (POC) was below 45% for 20 claims. The one remaining claim resulted in a POC greater than 52%. NIOSH will provide the Department of Labor with the list of all claims evaluated under this PER and request the return of the one claim that would now result in a POC greater than 50%.

    May 13, 2013

    About this Document: Evaluates all claims with employment in the residual period and a probability of causation less than 50% to determine the affect of the Aliquippa Forge TBD Revision 1.

    Summary: Twenty six claims with a probability of causation less than 50% were previously completed. Five of those had no employment in the residual period and were eliminated from further review. The dose was estimated for the remaining twenty one claims using the Revision 1 of the TBD. All twenty one remaining claims resulted in a probability of causation below 45%.
