Factors That Influence Annoyance

Aviation Noise Regulation and PoliciesFAR Part 36 – Noise Standards• Originally adopted in 1960, Part 36 prescribes noise standards for

issuance of new aircraft type certificates• Aircraft may be certificated as Stage 1- 4 based on their noise level,

weight, and number of engines (Stage 5 coming soon)• Stage 1 and 2 jet aircraft weighing greater than 75,000 lbs. not

permitted beyond 12/31/99; aircraft less than 75,000 beyond 12/31/15• Light fixed-wing and helicopters certified differently, not currently

subject to any kind of phase-out process

17

Aviation Noise Regulation and Policies

18

FAR Part 91 – General Operating and Flight Rules

The pilot in command of an aircraft is directly responsible for, and is the final authority as to, the operation of that aircraft

Minimum legal altitudes of 1,000’ over congested areas, except when necessary for takeoff or landing

Minimums of 500’ over less than congested areas, or no closer than 500’ to any person, vessel, vehicle, or structure

Helicopters may be operated lower than these minimums as long as the pilot complies with routes or altitudes specifically prescribed by the FAA

1,000’

500’

Aviation Noise Regulation and PoliciesFAR Part 150 – Airport Noise Compatibility Planning• Part 150 established a consistent noise reduction planning process;

requirements include:– Development of Noise Exposure Maps (NEM’s)– Development of Noise Compatibility Plans (NCP’s)– Public Input

• No non-compatible land use exists around HIO by FAA guidelines, therefore there is no formal FAA support for an NCP for the Hillsboro community

19

Aviation Noise Regulation and PoliciesFAR Part 150 – Airport Noise Compatibility Planning• Non-Commercial FAA compatibility guidelines

20

Note – all existing and forecast NEM’s to date for HIO show 65 and higher DNL levels are confined to Airport property.

Aviation Noise Regulation and PoliciesFAR Part 161 – Notice and Approval of Airport Noise and Access Restrictions• FAA process to establish airport access restrictions; i.e. curtailment of

operational hours (curfews), bans on aircraft types, etc.• Must satisfy six statutory requirements:

21

1. The restriction is reasonable, non-arbitrary, and non-discriminatory.2. The restriction does not create an undue burden on interstate or foreign commerce.3. The restriction maintains safe and efficient use of the navigable airspace.4. The restriction does not conflict with any existing Federal statute or regulation.5. The applicant has provided adequate opportunity for public comment on proposed

restriction.6. The restriction does not create an undue burden on the national aviation system.

• 14 not pursued due to low feasibility,25 due to low activity levels

• 13 and 20 thru RNAV procedures for jet aircraft only

• 10 – helicopters operate on txwy D, permanent pad in planning

• 23 – low feasibility due to airfield and operational impacts

• 26 – radar is under the FAA’s authority, in lieu the Port built a multilateration (MLAT) flight tracking system for noise monitoring purposes

•What is the status of the airshed?•How do we contribute to it?•Are we constrained by it?•What are some of the issues coming up?•What are we doing about our footprint?

Air Quality Context• Air quality is both regulated and non-regulated• Portland-Vancouver air quality meets federal health-based ambient air quality standards

• State continuing to develop its own program for air toxics• With the exception of lead, HIO’s contribution to the airshed is relatively small

– Less than 1% • The Port is actively working to track and improve performance at HIO

Lead• Federal 2018 –Unleaded fuels that can be used by most of the fleet on track to

be approved by FAA in late 2018.• Port Unleaded Fuel Study – Between 8.5% and 29.5% of HIO fleet can use

unleaded gasoline (ethanol free).• Port provided incentives to supply unleaded gasoline.

Diesel• Port working with regional governments and DEQ to explore the feasibility of

clean diesel public contracting requirements.

• Based on coordination with the tower and previous studies• Helicopters – 80% south / 20% north

Noise Calculation Grid• Contours connect points of the same value, similar to a topographic contour

• Visualization not available in INM

Noise Contours 65-75 DNL65 DNL is federal compatibility threshold

Noise Contours 55-75 DNL55 DNL is State of Oregon's Compatibility Threshold

Criteria Pollutant Emissions - Tons/Year

• Mixing height of 3,000 ft.

Supplemental Noise Metrics

• Used in the Runway 12L/30R Environmental Assessment (EA)• Based on the same calculation grid and shown with contours• Time Above - Time, in minutes, above a user-specified threshold• Number Above - Number of events above a user-specified threshold• No federal threshold, 70 dB used in EA (similar t a loud car, vacuum cleaner, freeway at 50 ft.)

Modeling Summary

• Modeling process is similar between INM+EDMS and AEDT• Common fleet ensures consistent inputs for noise and air quality• More aircraft from which to choose when modeling (3,000+ combinations)• Different helicopter noise modeling results vs. INM
