Code of Federal Regulations Title 20. Employees' Benefits § 20.702.212 Notice;  when given;  when given for certain occupational diseases

(a) For other than occupational diseases described in (b), the employee must give notice within thirty (30) days of the date of the injury or death. For this purpose the date of injury or death is:

(b) In the case of an occupational disease which does not immediately result in disability or death, notice must be given within one year after the employee or claimant becomes aware, or in the exercise of reasonable diligence or by reason of medical advice, should have been aware, of the relationship between the employment, the disease and the death or disability. For purposes of these occupational diseases, therefore, the notice period does not begin to run until the employee is disabled, or in the case of a retired employee, until a permanent impairment exists.

(c) For purposes of workers whose coverage under this Act is dependent on denial of coverage under a State compensation program, as described in § 701.401, the time limitations set forth above do not begin to run until a final decision denying State coverage is issued under the State compensation act.
