7 Noise and its Measurement Quiet bedroom Normal conversation Jet 1,000 ft. Rock concert 0 20dB 60dB 90dB 115dB +/ 1 db smallest change detectable to humans 8

8 Noise and its Measurement Quiet bedroom Normal conversation Jet 1,000 ft. Rock concert 0 20dB 60dB 90dB 115dB +/ 3 db is noticeable to most people 9

9 Noise and its Measurement Quiet bedroom Normal conversation Jet 1,000 ft. Rock concert 0 20dB 60dB 90dB 115dB +/ 10 db sounds twice as loud or twice as quiet 10

10 Noise and its Measurement Two jet 1,000 ft. Quiet bedroom Normal conversation Rock concert 0 20dB 60dB 93dB 115dB Adding two like sounds adds 3 db increase 11

11 Noise and its Measurement 83 db 65 db 71 db Double (or half) the distance between a sound and the receiver changes noise +/ 6 db 12

12 Noise and its Measurement Standard unit of measure is the decibel db measured on a logarithmic scale A-Weighted level (db) SEL Energy of an event, compressed into 1-sec Leq Average sound over a specified period Lmax Maximum noise level Duration Background noise level (ambient) 10 db increase = 10x the acoustic energy Time (seconds) 13

13 14 Equivalent Sound Levels

14 Factors That Influence Annoyance Acoustic Psychological Noise Level Event Duration Attitude Toward Source Trust Number of Events Time of Day Perceived Avoidability Fear Sleep Disturbance... Procedural Fairness... 15

15 16 Factors That Influence Annoyance

16 Aviation Noise Regulation and Policies FAR 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

17 Aviation Noise Regulation and Policies FAR Part 91 General Operating and Flight Rules 1, Minimum legal altitudes of 1,000 over congested areas, except when necessary for takeoff or landing The pilot in command of an aircraft is directly responsible for, and is the final authority as to, the operation of that aircraft Helicopters may be operated lower than these minimums as long as the pilot complies with routes or altitudes specifically prescribed by the FAA Minimums of 500 over less than congested areas, or no closer than 500 to any person, vessel, vehicle, or structure 18

18 Aviation Noise Regulation and Policies FAR 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

19 Aviation Noise Regulation and Policies FAR Part 150 Airport Noise Compatibility Planning Non-Commercial FAA compatibility guidelines Note all existing and forecast NEM s to date for HIO show 65 and higher DNL levels are confined to Airport property. 20

20 Aviation Noise Regulation and Policies FAR 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: 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. 21

22 Compatibility Study & Fly Friendly

23 2005 Compatibility Study & Fly Friendly Element Current Status Notes Aircraft Operations 1, 2, 4 9, 11 22, 24, 25 Airfield Improvements 3, 10, 23 All implemented with the exception of 14 and 25 Implemented with the exception of 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 Technology Stakeholder Involvement, Outreach Implemented with the exception of 26 All implemented 26 radar is under the FAA s authority, in lieu the Port built a multilateration (MLAT) flight tracking system for noise monitoring purposes 24

26 27 Air Quality 101 David Breen

27 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? 28

28 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 29
