NOISE ABATEMENT PROCEDURES

North Flow	The Initial Departure Corridor is 4 degrees each side of the 341 degree radial of the Sea-Tac Airport VOR, extending 8 DME north of the Airport and a minimum altitude of 4,000 feet before turning.
Between the hours of 10:00 pm and 6:00 am jet aircraft departing north are vectored west over Elliott Bay, then turned north or south over Puget Sound once out of Elliott Bay.
South Flow	The initial Departure Corridor is 4 degrees each side of the 161 degree radial extending 5 DME south of the airport and a minimum altitude of 3,000 before turning.
Reverse Thrust	Between the hours of 10:00 pm and 7:00 am, the use of extended reverse thrust is discouraged beyond what is necessary for operational or safety reasons.

AIRPORT CURFEWS

Prior to the phase-out of Stage 2 airplanes over 75,000 lbs in the U.S., there was a curfew on those operatons at the airport.

PREFERENTIAL RUNWAYS

During nighttime hours, 10pm to 6am, those aircraft equipped with flight management system (FMS) operate through the North Flow Nighttime Noise Abatement Corridor. This measure is operational when traffic and other conditions permit, as determined by the FAA. In such conditions, during nighttime hours, departures can be shifted from south to the north, thus utilizing the established noise abatement corridor. This procedure is limited to those times when it can be done safely and efficiently.

OPERATING QUOTA - NONE

ENGINE RUN-UP RESTRICTIONS

All engine run-ups require approval of Airport Operations. No aircraft engine run-up shall be conducted between the hours of 2200 and 0700 except:

a. Aircraft that are regularly scheduled to depart between the hours of 0600 and 0830 shall be allowed to run-up as necessary between 0600 and 0700. b. Engine runs necessary for engine checks at idle power or, if absolutely necessary, a run-up above idle not to exceed a total of two (2) minutes duration during this designated quiet period shall be allowed. Operations not in accordance with the run-up regulations are subject to public disclosure and fees as stated in the Sea-Tac International Airport Tariff #1.

Based on these Run-Up Restrictions, Tarriffs have been implemented. As of April 30, 2003 the fines associated with violating the run-up restrictions are:
First offense in one year	= Letter of Admonishment
Second offense in one year	= $1,000
Third offense in one year from first offense	= $2,000
Maximum fine within one year from first offense	= $8,000

APU OPERATING RESTRICTIONS - NONE

NOISE BUDGET RESTRICTIONS

Sea-Tac's Noise Budget Program was a 10 year program designed to speed up the phase-out of Stage 2 aircraft. This program ended in the year 2001, when all Stage 2 aircraft above 75,000 lbs. were phased out.

NOISE SURCHARGE - NONE

NOISE MITIGATION/LAND USE PLANNING PROGRAM INFORMATION

Type of Program	Date Implemented	Status
Sound Insulation (Residences and Public Buildings)	-	- Sea-Tac Airport's noise insulation program has been in progress for over 20 years. The noise remedy boundary includes communities close to the airport that are most highly impacted by airport noise. - The Port of Seattle has insulated over 9,300 single-family homes to-date out of an eligible 10,000. - The Port of Seattle insulated about half of the 22 classroom buildings at the local Highline Community College. - The Port of Seattle is participating in the reconstruction and insulation of 15 buildings in the Highline School District. Over a third of those buildings have been reconstructed, to date. - The Port of Seattle insulated five condominium complexes.
Purchase Assurance for Homeowners Located Within the Airport Noise Contours	-	The Port provides a Special Purchase Option (SPO) for homeowners whose homes have not been previously insulated by the Port and are adjacent to Port-owned property. The property first is acquired, then insulated and placed back on the open real estate market.
Avigation Easements	-	Securing easements for single-family projects fall under state law RCW 53.54.030, enacted in 1974 and amended in 1993 - which states: "Programs of sound proofing structures located within an impacted area - such programs may be executed without regard to the ownership, provided the owner waives damages and conveys and easement for the operation of aircraft, and for noise and noise associated conditions therewith, to the Port district". Mobile homes located on private land are eligible for an Easement Purchase Program. Because of inadequate structural integrity, mobile homes cannot be insulated against aircraft noise. Easements are purchased using a percentage of the King County property tax assessments. This program is voluntary and the purchase of easements is at the homeowner's request.
Zoning Laws	-	The Port provided grant money to pay for land use planning in the city of Burien, to assure compatible land use guidelines in new development.
Real Estate/Property Disclosure Laws	-	N/A
Acquire Land for Noise Compatibility to date	-	Four mobile home parks within the most highly affected areas have been acquired, and one is under way. Residents receive full federal relocation benefits.
Population within each noise contour level relative to aircraft operations	-	Based on the 1998 DNL noise contour: " 65 DNL= 9092 acres & 37,702 people approximately; " 70 DNL = 3794 acres & 7100 people approximately; " 75 DNL = 1559 acres & Zero people. See attached map below.
Airport Noise Contour Overlay Maps	1998	DNL Contour with Existing Land Use DNL Contour (close in view)
Total Cost of Noise Mitigation Programs to Date	2007 grants	2008: AIP grant of $1,950,145 for noise mitigation measures for one Highline School District school, $7,414,647 for the acquisition and relocation of 25 homes identified as in Phase 3 of the North Approach transition Zone, $2,635,208 (partial payment) for the acquisition and relocation of 45 residents in Town & Country Mobile Home Park (the remaining residents will be relocated with a grant from 2009).
Source of Noise Mitigation Program Funding for Aircraft Noise	-	Passenger Facility Charge, Bonds, Airport Development Funds, and Airport Improvement Plan.

NOISE MONITORING SYSTEM

Sea-Tac has 25 noise monitors that use Airport Noise and Operations Monitoring System (ANOMS) developed by Lochard Pty., Ltd. We are currently in the process of upgrading our software to the new version of GEMS, called ANOMS. Both provide an efficient system to gather, evaluate, and distribute information for noise monitoring programs. Both are a multi-user, multi-tasking system designed to provide a broad group of airport users with the data, reports, and maps to assist in the prompt and accurate identification of aircraft noise sources and analysis of operational data. The system consists of a computer that captures and processes flight track and noise monitoring data, receivers and recorders to monitor and record ATC/pilot communications, 25 noise monitors, and a comprehensive capability to relate noise complaints to aircraft operations and the noise they create. A real-time flight tracking system, which allows viewers to watch Puget Sound region flights and air traffic from their computer, is available on Sea-Tac Airport’s website: www.portseattle.org/community/environment/noiseabatement.shtml Noise Monitoring System Seattle-Tacoma International Brochure (provided by the airport).
