STATE OF NEW YORK ________________________________________________________________________ 1425 2025-2026 Regular Sessions IN SENATE January 9, 2025 ___________ Introduced by Sens. LIU, MYRIE, SANDERS -- read twice and ordered print- ed, and when printed to be committed to the Committee on Health AN ACT to amend the public health law, in relation to airport noise studies The People of the State of New York, represented in Senate and Assem- bly, do enact as follows: 1 Section 1. Article 13 of the public health law is amended by adding a 2 new title 14 to read as follows: 3 TITLE XIV 4 AIRPORT NOISE STUDIES 5 Section 1389-hh. Legislative findings and purposes. 6 1389-ii. Definitions. 7 1389-jj. Airport noise studies. 8 § 1389-hh. Legislative findings and purposes. 1. The legislature here- 9 by finds, determines, and declares that noise pollution causes a variety 10 of adverse human health impacts, many of which are related to noise 11 induced stress including hearing loss, hypertension, tachycardia, 12 increased cortisol release, sleep disruption, and cognitive impairment. 13 2. The legislature further finds and recognizes that the federal envi- 14 ronmental protection agency and the World Health Organization have 15 recommended a fifty-five day-night average sound level (DNL) noise expo- 16 sure level to protect the public from adverse human health impacts. 17 3. The legislature further finds and recognizes that the federal 18 aviation administration accepts as a metric for determining noise 19 impacts the community noise equivalent level (CNEL). 20 4. The legislature further finds that the community noise equivalent 21 level (CNEL) includes a penalty for increased sensitivity to noise 22 occurring during evening hours which are set aside for family and 23 student study time. 24 5. For these purposes, there shall be established a uniform metric for 25 measuring noise impacts that will be used by airports in New York state EXPLANATION--Matter in italics (underscored) is new; matter in brackets [ ] is old law to be omitted.

S. 1425 2 1 for the purpose of noise exposure maps (NEMs) and noise compatibility 2 programs (NCPs). 3 § 1389-ii. Definitions. For the purposes of this title, the following 4 definitions shall apply: 5 1. "Community noise equivalent level" (CNEL) means, in decibels, the 6 average daytime noise level during a twenty-four hour period, adjusted 7 to account for the lower tolerance of noise during evening and nighttime 8 periods in relation to daytime periods. 9 2. "Hourly noise level daytime" (HNLD) means, in decibels, the hourly 10 noise levels for the hours of 0700-1900. 11 3. "Hourly noise level evening" (HNLE) means, in decibels, the hourly 12 noise levels for the hours of 1900-2200. 13 4. "Hourly noise level nighttime" (HNLN) means, in decibels, the hour- 14 ly noise levels for the hours of 2200-0700. 15 § 1389-jj. Airport noise studies. 1. For the purpose of airport noise 16 studies, all contour maps shall be completed using the community noise 17 equivalent level. This shall include, but shall not be limited to, 18 federal aviation regulation part one hundred fifty studies, airport 19 noise exposure maps (NEMs), and airport noise compatibility programs 20 (NCPs). 21 2. The community noise equivalent level (CNEL) shall be calculated by 22 the following: CNEL = 10 log (1/24) ({sigma} antilog (HNLD/10) + 3 23 {sigma} antilog (HNLE/10) + 10 {sigma} antilog (HNLN/10)). 24 § 2. This act shall take effect immediately.
