Congress finds that employees who worked in Department of Energy test sites and later contracted chronic silicosis should also be considered for inclusion in the compensation program. Recognizing that chronic silicosis resulting from exposure to silica is not a condition unique to the nuclear weapons industry, it is not the intent of Congress with this subchapter to establish a precedent on the question of chronic silicosis as a compensable occupational disease. Consequently, it is the sense of Congress that a further determination by the President is appropriate before these workers are included in the compensation program.
