LA/ONTARIO INTERNATIONAL AIRPORT PART 150 NOISE EXPOSURE MAP UPDATE  

Los Angeles World Airports (LAWA) is updating the Noise Exposure Map (NEM) for LA/Ontario International Airport (ONT) to resume eligibility for federal funding for the City of Ontario Quiet Home Program (QHP).  

In Fall 2012, the FAA notified officials of the QHP that, due to the age of the existing NEM developed in 1990, the QHP is no longer qualified for FAA noise mitigation grants. The QHP uses the NEM to determine participant's eligibility and receives funds from both FAA and LAWA to perform noise mitigation measures (such as sound insulation and land acquisition of residential properties) in the City of Ontario. In order to resume eligibility for this federal funding, LAWA has initiated the process to update the NEM.

What is Part 150

As part of this NEM update process, LAWA must follow a set of procedures and standards under the U.S. Code of Federal Regulations, Title 14 Part 150, entitled "Airport Noise Compatibility Planning", when assessing noise exposure and when developing means to mitigate its effects. This regulation is commonly referred to as Part 150.

Part 150 sets guidelines for airport operators to document aircraft noise exposure, and to establish noise abatement and compatible land use programs. These noise programs must be approved by the FAA in order to qualify for potential federal funding for noise mitigation efforts such as sound insulation and land acquisition. The Part 150 regulations are further clarified by the FAA in Advisory Circular 150/5020-1.

A Part 150 Study is an in-depth noise and land use compatibility study that involves working with the community to address its concerns and developing a detailed analysis of aviation-related noise levels and the variables that affect them. It consists of two technical elements:

  • Noise Exposure Maps (NEMs), which identify the levels of aircraft noise in areas around the airport
  • Noise Compatibility Program (NCP), which are measures designed to reduce noise and incompatible land uses within the noise exposure area

ONT completed its first Part 150 study in 1990 which included both elements. Over time, airport operations change, technology changes, and land use patterns can change. The current project will update the Noise Exposure Maps to reflect upon current conditions and forecast aircraft operational activity at the airport.

The NEMs include aircraft noise exposure contours created using the FAA's Integrated Noise Model (INM). The noise contours are presented on a map that depicts the airport's layout and land uses within the communities surrounding the airport. These contours also reflect the noise exposure from aircraft operations occurring during the year of submission to the FAA (2015 expected) and a five-year forecast (2020) as mandated by the FAA.

The NCP is a summary of analyses and proposed actions that the FAA, airport operators, active airlines, and communities near the airport can perform to reduce existing and future aircraft noise and land use incompatibilities. These actions may include noise abatement, noise mitigation, and/or other preventive measures.

ONT Part 150 NEM Update Process

LAWA has selected the noise consulting firm Harris Milller Miller & Hanson, Inc. (HMMH) to assist with this project. The project to update the ONT Part 150 NEMs will include, but is not limited to, the following major tasks:

  • Inventory ONT existing conditions;
  • Prepare updated ONT fleet mix forecasts for year of submission (2015 expected) and a five-year forecast (2020);
  • Prepare draft and final updated Noise Exposure Maps;
  • Prepare NEM supporting documentation; and
  • Conduct stakeholder and public consultations.

Project Schedule

LAWA has identified the following major project milestones with estimated completion dates. Additional details will be added as the project progresses.

  • BOAC approves contract with HMMH                                  January 13, 2014 
  • LAWA issues Notice to Proceed to HMMH                            March 1, 2014
  • First public workshop to introduce the project                        May 1, 2014
  • Release Draft NEM Update for public/stakeholder review         August 2015
  • Begin public/stakeholder review/comment period                   August 2015
  • Second public workshop on Draft NEM Update                      September 2015
  • End public/stakeholder comment period                               September 2015
  • Submit Final NEM update to FAA                                        November 2015
  • FAA Completes 180-day review period                                 May 2016

LAWA estimates that the project will take approximately 18-24 months to complete and submit the maps and supporting documentation to the FAA. The FAA will then review the submitted documents and issue a notice of acceptance for the updated NEMs if they comply with the Part 150 requirements.

Public Outreach

An integral part of the ONT Part 150 NEM Update project includes a public outreach process that provides consultations with the public, airport stakeholders, the state, local governments, the airlines and other aircraft operators to afford them the opportunity to submit their views, information, and comments during the project.

LAWA plans to include two public workshops where community members can learn about the project and provide comments. The first workshop will be held at the beginning of the project to introduce the project's objective and process, and a second workshop will be held at the end to share the results of the NEM update and solicit comments before final submittal to the FAA. 

First Public Workshop

On Thursday, May 1, 2014, LAWA hosted the first of two public workshops for the ONT Part 150 Noise Exposure Map Update. Interested residents and stakeholders attended the workshop between 5:30 p.m. and 7:30 p.m. at the ONT Administration Building. Airport officials and consultants were present to answer questions regarding the NEM update process. A brief 15-minute presentation was given at 6 p.m.
