NOISE REMEDY PROGRAM Sound Insulation Program Homes Insutated Homeowners Initiated Into Program Transaction Assistance Sales Completed Special Purchase Option Homes Bought Acquisition Program Homes Bought Sound Insulation Program On January 1,1991,the rateof insulationwas increased from 175 to 350 homes per year as the result of the Noise Mediation Agreement. The "Cost Share" program has been converted to the "Standard Insulation" program which means that the Port pays 100°k of the costs. The Hardship Committee is made up of area residents and was formed in June,1990. A modified priority system, giving credit for the length of time an individual is on the waiting list, began on January 1, 1991. Sea-Tac Noise Advisory Committee The Noise Mediation Agreement established the Sea- Tac Noise Advisory Committee (SNAC) to monitor implementation of all mediated noise abatement and mitigation prograims. This report is published quar- � terly to assist SNAC with its function. SNAC member- ship represents the Air Transport Association, the Federal Aviation Administration, the Airline Pilots As- sociation, airport users, the Port of Seattle, and citi- zens representing various geographic areas. The citi- zens currently seated on SNAC are Irene Jones, Bob Rudolph, John Musgrave,_ Jim Lynch, and John• Whitlock. Alternate members are John Barber, Lorelei Herres, and Bill Whisler.

Issuance of a regular variance requires public notification and a comment process. Temporary Variance: Written permission to operate outside the provisions of this program up to four months. Exemptions: Cases where maintenance of the aircraft, delays due to unforeseen or emergency circumstances, or factors beyond the control of the carrier affect the scheduled time of the operation. Violations: Stage 2 operations determined to be in violation of the program and have been subject to corrective or penalty actions. � Operations Analyzed: Operations that appear to be Stage 2, during the restricted hours, that need further analysis regarding aircraft type and reason for operation. For example, analysis may determine these flights to be Stage 3 aircraft, aircraft hushkitted to meet Stage 3 requirements, operating with variances, exemptions, or violations. Operations Still Under Analysis: Operations that appear to be Stage 2, during the restricted hours, for which information is still being gathered. Corrective Actions: Stage 2 operations identified as violating the program, for which the responsible airline has implemented an acceptable corrective action. This action may include changing schedules or utilizing Stage 3 aircraft. Resolution plans may precede an admonishment letter, in which case no admonishment will be sent. Penalty Actions: Actions the Port of Seattle has taken against an airline with flights in violation. Penalties include admonishment letters and fines. One penafty action may be taken in an effort to resolve several violations.

For example, a high rate of south flow departures results in higher average noise levels at the south remote noise monitoring site (RMS 1) and lower average noise levels at the north site (RMS 7). The charts below show the changes in average noise over time. (NOTE: Formerly, RMS 8 was used as the noise data collection site for this report but was out of seroice since October 1991 due to construction on the school grounds where it is located. RMS 7 is lacated near RMS 8, so the Port of Seattle now utilizes this for on-going analysis and reporting.) Noise data collected from the eleven remote sites of the permanent noise monitoring system indicate a Z F LL � W < _ W � a lin in n i levels since 1990. Ai ort continuin dec e o se � 9 noise eaked in 1990 and has gradually declined p since. The decline is more significant for communities south of Sea-Tac since there are more departures overthose communities. Improvements in the fleet mix also help. When compared with Stage 2 jets, Stage 3 jets show a greater reduction in departure noise than in arrival noise. Although Stage 3 jets are quieter on landing than Stage 2 jets, the differences in noise reductions are not as significant as they are for jet departures. Consequently, communities that experience a higher number of departures should perceive greater noise reductions.
