ITEM 3

RESPONSE TO MSP FAIRSKIES REQUESTS

(CONTINUED FROM THE JANUARY 24 DISCUSSION)

NOISE OVERSIGHT COMMITTEE MARCH 21, 2018

Item 3: Response to MSP FairSkies Requests

September 20, 2017 NOC Meeting representatives from MSP FairSkies addressed the Committee requesting that NOC/MAC:

• 1. Enhance the NOC with greater stakeholder (citizen) representation
• 2. Establish a goal to reduce noise
• 3. Produce a 55 dB and N65 NEM/Contour

Item 3: Response to MSP FairSkies Requests

In response to the first two requests, on January 24, 2018 the NOC discussed the following:

• 1. Enhance the NOC with greater stakeholder (citizen) representation
• Concurred that the current balance of six user representatives and six

community representatives was appropriate for the NOC membership

• Took action to establish a NOC Bylaw Subcommittee to review the bylaws

and recommend changes to enhance citizen engagement during meetings

• 2. Establish a goal to reduce noise
• Took action to solidify the goal to mitigate homes out to the actual

60 dB DNL contour by the year 2024

• Agreed that the establishment of this goal does not preclude

further discussion to establish Committee goals in the future

Item 3: NOC Action – FairSkies Request: NOC/MAC Publish 55 dB DNL and N65 Contours & NEMs

Request 3: Does the Committee recommend publication of 55 dB DNL and N65 noise contours and NEMs?

Item 3: Background – FairSkies Request: NOC/MAC Publish 55 dB DNL and N65 Contours & NEMs

OBJECTIVES

Objective #1: Help advance a more restrictive noise metric/threshold in before FAA returns to MSP for RNAV SID implementation Objective #2: Acknowledge and validate that residents who live beyond the 60 DNL noise contour experience aircraft

• verflights and noise

Item 3: Background – FairSkies Request: NOC/MAC Publish 55 dB DNL and N65 Contours & NEMs

EVALUATING TACTICS TO ACHIEVE OBJECTIVES

Are there relevant situational factors? Are there unintended consequences/risks that should be considered? Do the proposed tactics provide the most effective means to achieve the objectives?

Item 3: NOC Action – FairSkies Request: NOC/MAC Publish 55 dB DNL and N65 Contours & NEMs

Does the Committee recommend publication of 55 dB DNL and N65 noise contours and NEMs?

Benchmarking Study Objectives

• Understand the constraints imposed on U.S. airport noise programs due to the

highly-regulated environment in contrast with airports in other countries

• Provide an independent and transparent review of the MAC Noise Program Office

and related noise abatement activities as compared with peer airports in the U.S.

• Identify improvement opportunities for the MAC Noise Program Office and MSP

Noise Oversight Committee (NOC).

Proposed Scope of Work

Identify noise program components and activities to benchmark Develop data gathering strategy Data collection Data analysis Draft report Final report

37

Task 1: Identify noise program activities to benchmark

• HMMH will work with MAC Noise Program Office and NOC to develop list of

activities to benchmark, including:

• Operational Measures
• Mitigation and Land Use Measures
• Program Management and Innovate use of Technology
• Stakeholder Engagement
• Research and policy

38

Task 2: Develop survey

• HMMH will develop an online survey (e.g., SurveyMonkey)
• Survey respondent list will be developed from ACI-NA and AAAE mailing lists
• HMMH will review draft and final survey recipient list with MAC staff

39

Task 3: Data collection

• Survey link will be sent from MSP to survey recipients
• After two weeks, HMMH will send recipients a reminder
• After another week, HMMH will call recipients and offer to assist with completion
• HMMH will research and document current laws/rules/regulations/policies in the

U.S. related to noise and mitigation

40

Task 4: Data/Policy analysis

• HMMH will summarize the data collected through online and telephone survey
• HMMH will summarize implications of U.S. laws/rules/regulations/policies

every 10 days on average  The 2007 forecast average is 274.9 Hushkit flights per day

• Nighttime operations in 2017 decreased by 3.2

average daily operations from the 2007 forecast number

• The 2017 actual noise contour is smaller than

the 2007 forecast contour by 27% in the 60 DNL contour and 38% in the 65 DNL contour

Item 5: 2017 Annual Noise Contour Report and Mitigation Activity

*Based on airport operations counts documented by the FAA for MSP in 2017.

Two areas of the 2017 contour have extended beyond the 2007 forecast contour

• 2017 had more balance between North

Flow and South Flow operations compared to the previous 2 years due to the FAA’s efforts to refine traffic management during Converging Runway Operations

• Reduction of noise exposure in 2017

compared to 2016 under the arrival lobes

• f Runways 12L and 12R (dark blue)
• Increased noise exposure in 2017 under

the arrival and departure lobes of Runways 30L and 30R (light blue)

Item 5: 2017 Annual Noise Contour Report and Mitigation Activity

Overview of Mitigation Eligibility per the Amended Consent Decree The current program will provide mitigation to eligible homes until 2024 based on actual noise exposure 5 dB DNL further into the community than the federal threshold of 65 dB DNL The home must meet the following 2 criteria: (a) The community in which the home is located has adopted local land use controls and building performance standards to ensure the practices are consistent with the noise mitigation provided by the MAC. (b) The home is located for 3 consecutive years in the actual 60 DNL noise contour and within a higher mitigation area when compared to the original program.

Item 5: 2017 Annual Noise Contour Report and Mitigation Activity

Overview of Mitigation Eligibility per the Amended Consent Decree The MAC will provide 2 different packages depending on exposure area:

• Eligible homes within the 63 dB DNL contour receive the Full 5dB Reduction Package, designed to reduce interior

noise levels by an average of 5 decibels

• Eligible homes within the 60 db DNL contour receive the Partial Noise Reduction Package, which comes with two
• ptions:

 Central air conditioning + $5,503* of mitigation products and services; or  $19,262* of noise mitigation products and services The MAC will provide mitigation to homes the year following eligibility determination. The only residential properties that currently meet the mitigation eligibility criteria are located in the City of Minneapolis.

Item 5: 2017 Annual Noise Contour Report and Mitigation Activity

*Any reimbursement or mitigation improvements previously provided by the MAC will be deducted from the dollar amounts; dollar amounts will be adjusted according to the project year CPI.

VORTEX GENERATOR NOISE MONITORING STUDY

Study Results Noise monitoring began on August 30, 2017 concluded on October 12, 2017

• 9,181 total noise events recorded
• 4,033 correlated to MSP aircraft operations

(3,527 arrivals and 506 departures)

• 453 correlated to Airbus A320 family arrivals

(excluding United Airlines)

• 29 were determined to be equipped with

vortex generators and 424 were non- equipped

Item 6: Vortex Generator Noise Monitoring Study

Study Results The vortex generator data had Lmax noise level differences from -0.4 to +1.6 dBA, SEL noise level differences from -1.0 to +1.2 dBA and average duration from -1 to +5 seconds. When taking aircraft noise measurements from the ground during this phase of flight, staff found the measured aircraft noise events struggled to exceed the ambient noise level in the

• community. Therefore, quantifying the noise reduction benefits provided by these devices from

the ground becomes extremely difficult. The study limitations included the low threshold settings required to collect aircraft arrival events between 5,000 and 9,000 feet in altitude, which resulted in noise level data that was impacted by louder community events; and the small sample of vortex generator-equipped aircraft operations that were available to analyze.
