Section 7: ENVIRONMENTAL HEALTH 7.1 NOISE 7.1.1 Threshold All development in Everett must be in conformance with the requirements of EMC 20.08, the Noise Control Ordinance. Noise studies may be required to determine if a proposal is in conformance with the ordinance. Engine run-up noise is exempt during daytime hours from the City and Counry noise regulations, but can result in significant short-term noise levels in residential areas. Boeing is permitted to add additional engine run-up stations provided a noise study is completed which documents that noise levels will not exceed those established in the 1991 EIS for the Boeing Expansion. Other than noted above, any use that is exempt or partially exempt &om EMC 20.08 and that exceeds the standards in EMC 20.08, including new jet engine run-up stations, must submit additional SEPA analysis of noise impacts. The City's Responsible O�cial may impose conditions to mitigate impacts beyond that required in the noise ordinance. 7.1.3 Mitigation Measures Waming devices on vehicles (back up beepers) aze exempt from the City's noise ordinance, but aze perceived as irritating by most people.
