compatibility planning. The Part 150 regulations establish guidelines for technical aspects of aircraft noise analysis and the public participation process for airports choosing to prepare airport noise compatibility plans.<\/p><p>Part 150 Study involves six major steps:<\/p><p style=\"padding-left: 30px;\">1. Identification of airport noise and land use issues and incompatibilities<br \/>2. Definition of current and future noise exposure contours<br \/>3. Evaluation of alternative measures for abating noise that impact the 65 Day Night Level (DNL) noise contour (e.g., changing aircraft flight paths), mitigating <br \/>the impact of noise (e.g., sound insulation), and managing local land uses (e.g., airport-compatible zoning)<br \/>4. Development of a Noise Compatibility Plan (NCP)<br \/>5. Development of an implementation and monitoring plan<br \/>6. FAA review and approval of the recommended NCP, including the analysis of alternatives, the compatibility plan, and the implementation and monitoring plan.<\/p><p>The Part 150 Study process is designed to identify noise sensitive land uses surrounding an airport, and to recommend measures to both correct existing incompatibilities and to prevent future incompatibilities. For Part 150 Study purposes, noise sensitive land uses are generally defined as residences or public use facilities (libraries, churches, schools, nursing homes and hospitals) within the 65 Day-Night Average Sound Level (DNL) noise contour, the area the FAA defines as impacted by aircraft noise.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-1292\" class=\"elementor-tab-title\" data-tab=\"2\" role=\"button\" aria-controls=\"elementor-tab-content-1292\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><i class=\"fas fa-plus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><i class=\"fas fa-minus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" tabindex=\"0\">Why prepare a Part 150 Study?<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-1292\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"2\" role=\"region\" aria-labelledby=\"elementor-tab-title-1292\"><p>The purpose for conducting a Part 150 Study at an airport is to develop a balanced and cost-effective plan for reducing current noise impacts from an airport&#8217;s operations, where practical, and to limit additional impacts in the future. By following the process, the airport operator is assured of the FAA&#8217;s cooperation through the involvement of air traffic control professionals in the study and the FAA&#8217;s review of the recommended Noise Compatibility Program (NCP). The decision to undertake noise compatibility planning is normally voluntary on the part of the airport operator. As part of the Record of Decision for Environmental Impact Statement for the relocation of the south runway at CMH, the Columbus Regional Airport Authority (CRAA) has committed to reviewing the Part 150 Study at CMH.<\/p><p>An airport with an FAA-approved NCP also becomes eligible for funding assistance for the implementation of approved measures.<\/p><p>Among the general goals and objectives addressed by a Part 150 Study are the following:<\/p><ul><li>&#8211; To reduce, where feasible, existing and future noise levels over existing noise-sensitive land uses;<\/li><li>&#8211; To reduce new noise-sensitive developments near the airport;<\/li><li>&#8211; To mitigate, where feasible, adverse impacts in accordance with Federal guidelines;<\/li><li>&#8211; To provide mitigation measures that are sensitive to the needs of the community;<\/li><li>&#8211; To minimize the impact of mitigation measures on local tax bases; and<\/li><li>&#8211; To be consistent, where feasible, with local land use planning and development policies.<\/li><\/ul><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-1293\" class=\"elementor-tab-title\" data-tab=\"3\" role=\"button\" aria-controls=\"elementor-tab-content-1293\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><i class=\"fas fa-plus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><i class=\"fas fa-minus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" tabindex=\"0\">How long will the Part 150 Study take to complete?<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-1293\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"3\" role=\"region\" aria-labelledby=\"elementor-tab-title-1293\"><p>The CRAA officially began the Study in August 2019.

This information is being used to ensure that the input data into the AEDT is as accurate as possible.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-1295\" class=\"elementor-tab-title\" data-tab=\"5\" role=\"button\" aria-controls=\"elementor-tab-content-1295\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><i class=\"fas fa-plus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><i class=\"fas fa-minus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" tabindex=\"0\">What is the Aviation Environmental Design Tool (AEDT)?<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-1295\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"5\" role=\"region\" aria-labelledby=\"elementor-tab-title-1295\"><p>The FAA has developed the Aviation Environmental Design Tool (AEDT) for evaluating aircraft noise impacts in the vicinity of airports. The AEDT is the FAA&#8217;s standard tool for determining the predicted noise exposure in the vicinity of airports. The FAA requires the use of AEDT to develop noise exposure contours in Part 150 Studies. The AEDT utilizes flight track information, aircraft fleet mix, aircraft flight profiles and terrain as inputs. The AEDT produces noise exposure contours that are used for land use compatibility maps. The AEDT includes built-in tools for comparing contours and easy export to commercial Geographic Information Systems.<\/p><p>The AEDT replaced the previous noise modeling software, the Integrated Noise Model, in 2015 which was used for the 2007 Part 150 Study at CMH.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-1296\" class=\"elementor-tab-title\" data-tab=\"6\" role=\"button\" aria-controls=\"elementor-tab-content-1296\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><i class=\"fas fa-plus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><i class=\"fas fa-minus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" tabindex=\"0\">What is DNL?<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-1296\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"6\" role=\"region\" aria-labelledby=\"elementor-tab-title-1296\"><p>The Day-Night Average Sound Level metric describes the total noise exposure during a given period. DNL is a metric used for predicting the average long term noise exposure on a population. In computing DNL, an extra weight of 10 dB is assigned to any sound levels occurring between the hours of 10:00 p.m. and 7:00 a.m. This is intended to account for the greater annoyance that nighttime noise is presumed to cause for most people. This extra weight treats one nighttime noise event as equivalent to 10 daytime events of the same magnitude.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-1297\" class=\"elementor-tab-title\" data-tab=\"7\" role=\"button\" aria-controls=\"elementor-tab-content-1297\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><i class=\"fas fa-plus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><i class=\"fas fa-minus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" tabindex=\"0\">What are Noise Exposure Maps (NEM)?<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-1297\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"7\" role=\"region\" aria-labelledby=\"elementor-tab-title-1297\"><p>Noise Exposure Maps (NEMs) identify the noise exposure of the current operating conditions, and projected future conditions.
