In September 1973, the Port of Seattle outlined a plan to acquire approximately 610 residential properties and 75 acres of open land surrounding Sea-Tac International Airport to create expanded clear zones north and south of the runways. The total estimated property cost was $15.46 million, with the Port anticipating over $8 million in federal FAA assistance and covering the remainder from airport revenues between 1974 and 1977. Under the best-case scenario, actual land acquisition could not begin until after July 1, 1974, following required environmental impact statements, housing relocation plans, and a multi-month FAA review process.

This 1973 U.S. Environmental Protection Agency document establishes scientific criteria for understanding how noise affects public health and welfare, including hearing damage, annoyance, communication interference, and property value loss. Prepared by EPA's Office of Noise Abatement and Control under the Noise Control Act of 1972, it describes cause-and-effect relationships between noise exposure and human health impacts. The criteria laid out in this document were intended to serve as a foundation for developing future noise standards and regulations, though the document itself does not constitute a standard or regulation.
