In November 1990, the National Institute for Occupational Safety and Health (NIOSH) received a request for a Health Hazard Evaluation (HHE) from the plant manager, Golden Valley Electric Association, Healy Power Plant, Healy, Alaska. The request stated that the employees had complained about irritating odors in the plant, smoke from the coal pulverizers, and exposure to morpholine and amine, and that two employees were recently diagnosed with asthma. As a first step in this investigation, all employees were asked to complete a screening questionnaire which was mailed to them. After reviewing the questionnaire responses, NIOSH investigators conducted an initial environmental and medical evaluation at the plant May 30 - June 9, 1991. An interim report containing the results of the first industrial hygiene survey was issued by NIOSH in December 1991. Concern was subsequently expressed by several employees that the evaluation was conducted during a time period when the plant's doors and windows were open and therefore would not reflect the worst-case conditions of the winter months, when the plant is closed off to the outside environment.
