Portland International Jetport Part 150 Noise Advisory Committee Meeting 2 April 4, 2002 6:00PM Portland Jetport Conference Room I. Introductions The meeting began at 6:15pm with 20 people present. Name: Jerry Angier Tom Ainsworth Dick Armstrong Linda Boudreau Richard Doucette Paul Ferguson Ed Green Roger Green Bruce Grieco Becky Haines Jean Heath Kathy Latendresse Robert Miller Jeff Monroe Michael Musca Ralph Nicosia Rusin Paul Ouelette Jeff Schultes John Silva Nathan Smith Organization Represented: Greater Portland Chambers of Commerce Stroudwater Neighborhood, Portland citizen, Cape Elizabeth Noise Advisory Committee; Councilor, City of South Portland FAA Loveitt s Field Homeowners Association, South Portland FAA retired Delta Air Lines Captain Ferry Village Neighborhood Conservation Association, South Portland noise consultant, HMMH Willard Neighborhood Association citizen, Ferry Village, South Portland noise consultant, HMMH Transportation Director, City of Portland Assistant Airport Manager, Portland Jetport FAA Noyes Street, Portland Airport Manager, Portland Jetport FAA Noise Advisory Committee (Chair); Councilor, City of Portland
II. Comment from Kathy Latendresse The meeting agenda was preceded by Kathy Latendresse s comments that aircraft using the Harbor Visual Approach directly affect her and her neighbors whose homes backyards abut the harbor. Kathy asked for a noise monitor to be placed on her property and that the study propose an alternate to the Harbor Visual Approach. II. Presentation of Aircraft Activity Levels B.Miller and R.Haines presented historic aircraft activity levels at Portland, Maine and preliminary proposed 2002 levels. III. Presentation of Aircraft Types B.Miller and R.Haines presented aircraft types ( aircraft mix ) for scheduled passenger operations at the Portland Jetport. IV. Discussion of Noise Monitoring Program Committee members expressed concerns over runway 11/29 closure from 10:30pm until 6:00am beginning early May and the effect on the monitoring program. Jeff Schultes: At least one late night arrival and one early morning departure (DAL) will be cancelled short term (expected to return eventually). Runway closure may cause grouping of arrivals around 10:00pm. Potential for late night shift to short runway (18/36) if inclement weather in other parts of the country delay flights. Not expected consistently. If inclement weather in PWM (ILS needed) and aircraft does not arrive before runway closure at night, aircraft will not land at PWM (ILS approach to 11 and 29 only). Tom Ainsworth: Concern over mid-may to mid-june time period. Wind shifts increase use of 18/36. Ed Green: Can get historical weather data from Gray, ME, but it would be difficult to pick out specific time periods each year where increased use of 18/36 is observed. Jean Heath expressed concerns over modeled data vs. actual (measurement) data. She requested a base line comparison of model results to actual measurement data and suggested that all the money and effort put into a Part 150 study will not be worth very much if community does not have confidence in results of model. Tom Ainsworth: Expressed an interest in study addressing ambient noise levels increasing in early AM and late PM. Also low frequency noise. Ralph Nicosia Rusin: Encouraged committee to consider inputs to model. DNL does not illustrate differences within each contour. Not everyone within the 60 db DNL contour experiences the same noise. Arrival and departure profiles-may be non-standard at Portland. Actual aircraft profiles will be looked at in radar data. Model may be adjusted for how actual aircraft perform and are flown. Ed Green: Procedure at PWM is climb unrestricted to 3000. Conditions permitting, continue climb.
Jean Heath expressed concerns over issues with site selection in previous Part 150. Asked community representatives to come up with 3 to 4 addresses of possible site locations in their neighborhood. M.Musca will collect addresses and forward to consultants for site selection. Dick Armstrong: Does not believe that the Harbor Visual Approach is an effective noise abatement measure. Expressed concern that when aircraft are cleared for the Harbor Visual Approach, they cut across Cape Elizabeth and/or South Portland instead of intended route. Ed Green: There are problems with pilots picking out checkpoints at night. The Harbor Visual Approach is not used after sunset. When it is given, pilots are sometimes given vectors that take the aircraft over residential areas. It was decided that monitoring site information request should go to neighborhood presidents, who will coordinate site requests and forward them to Michael Musca at the Portland Jetport. Monitoring site requests are due to HMMH by April 25, 2002. V. Discussion on Airline Leases Councilor Smith led a discussion of the negotiated lease between the City of Portland and the air carriers. Tom Ainsworth and Paul Ouelette expressed disappointment with the involvement of the committee in the lease negotiation. To request a mailed copy of the airline leases, please e-mail Michael Musca (mmm@ci.portland.me.us). VI. Next Meeting The next Noise Committee is scheduled for June 11, 2002 at 6 p.m. in the Portland International Jetport Conference Room.
