30.231—How does a claimant prove employment-related exposure to a toxic substance at a DOE facility or a RECA section 5 facility?
To establish employment-related exposure to a toxic substance at a Department of Energy facility or RECA section 5 facility as required by § 30.230(d), an employee, or his or her survivor(s), must prove that the employee was employed at such facility and that he or she was exposed to a toxic substance in the course of that employment.
(a)
Proof of employment may be established by any trustworthy records that, on their face or in conjunction with other such records, establish that the employee was so employed and the time period(s) of such employment.
(b)
Proof of exposure to a toxic substance may be established by the submission of any appropriate document or information that is evidence that such substance was present at the facility in which the employee was employed and that the employee came into contact with such substance. OWCP site exposure matrices may be used to provide probative factual evidence that a particular substance was present at either a DOE facility or a RECA section 5 facility.
