Location: Pasadena, Texas

Also known as: Pasadena Chemical Corp., Olin Mathieson Chemical Co., Mobil Mining and Minerals Co.

Note: The Secretary of Energy is granted authority to designate the covered facilities of EEOICPA. On May 26, 2011, the Department of Energy (DOE) published a Federal Register Notice that de-listed Mathieson Chemical Co. as an Atomic Weapons Employer (AWE) facility.

Special Exposure Cohort Petition Information

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.
