New York Codes, Rules and Regulations › Title 16 - DEPARTMENT OF PUBLIC SERVICE › Chapter X - Certification Of Major Electric Generating Facilities › Subchapter A - Regulations Implementing Article 10 Of The Public Service Law As Enacted By Chapter 388, Section 12, Of The Laws Of 2011 › Part 1001 - Content Of An Application › Section 1001.19 - Exhibit 19: noise and vibration

Current through Register Vol. 46, No. 28, July 10, 2024
Exhibit 19 shall contain:
A study of the noise impacts of the construction and
					 operation of the facility, related facilities and ancillary equipment. The name
					 and qualifications to perform such analyses of the preparer of the study shall
					 be stated. If the results of the study are certified in any manner by a member
					 of a relevant professional society, the details of such certification shall be
					 stated. If any noise assessment methodology standards are applied in the
					 preparation of the study, an identification and description of such standards
					 shall be stated. The study shall include:
(a) A map of the study area showing the
				  location of sensitive sound receptors in relation to the facility, related
				  facilities and ancillary equipment (including any related substations). The
				  sensitive sound receptors shown shall including residences, outdoor public
				  facilities and areas, hospitals, schools and other noise-sensitive
				  receptors.
(b) An evaluation of
				  ambient pre-construction baseline noise conditions, including A-weighted/dBA
				  sound levels, prominent discrete (pure) tones, at representative potentially
				  impacted noise receptors, using actual measurement data recorded in winter and
				  summer and during day and night as a function of time and frequency using a
				  suitable and suitably calibrated sound level meter (SLM) and octave band
				  frequency spectrum analyzer, or similar equipment. The ambient pre-construction
				  baseline sound level should be filtered to exclude seasonal and intermittent
				  noise.
(c) An evaluation of future
				  noise levels during construction of the facility and related facilities
				  including predicted A-weighted/dBA sound levels at potentially impacted and
				  representative noise receptors, using computer noise modeling.
(d) An estimate of the noise level to be
				  produced by operation of the facility, related facilities and ancillary
				  equipment assuming wind-induced background noise or stable atmospheric
				  conditions, as appropriate, and not assuming any attenuation of sound that
				  transiently occurs due to weather or temperature.
(e) An evaluation of future noise levels
				  during operation of the facility, related facilities and ancillary equipment
				  including predicted A- weighted/dBA sound levels,, prominent discrete (pure)
				  tones, and amplitude modulated sound, at potentially impacted and
				  representative noise receptors, using computer noise modeling, and an analysis
				  of whether the facility will produce significant levels of low frequency noise
				  or infrasound.
(f) A statement in
				  tabular form of the A-weighted/dBA sound levels indicated by measurements and
				  computer noise modeling at the representative external property boundary lines
				  of the facility and related facilities and ancillary equipment sites, and at
				  the representative nearest and average noise receptors, for the following
				  scenarios:
(1) Daytime ambient noise level - a
				  single value of sound level equivalent to the level of sound exceeded for 90
				  percent of the time during the daytime hours (7 am - 10 pm) of a year
				  (L90).
(2)
				  Summer nightime ambient noise level - a single value of sound level equivalent
				  to the level of sound exceeded for 90 percent of the time during the nightime
				  hours (10 pm - 7 am) during the summer (L90).
(3) Winter nightime ambient noise level - a
				  single value of sound level equivalent to the level of sound exceeded for 90
				  percent of the time during the nightime hours (10 pm - 7 am) during the winter
				  (L90).
(4)
				  Worst case future noise level during the daytime period - the daytime ambient
				  noise level (L90), plus the noise level from the
				  proposed new sources modeled as a single value of sound level equivalent to the
				  level of sound exceeded for 10 percent of the time by such sources under normal
				  operating conditions by such sources in a year
				  (L10).
(5)
				  Worst case future noise level during the summer nightime period - the summer
				  nightime ambient noise level (L90), plus the noise level
				  from the proposed new sources modeled as a single value of sound level
				  equivalent to the level of sound exceeded for 10 percent of the time by such
				  sources under normal operating conditions by such sources in a year
				  (L10).
(6)
				  Worst case future noise level during the winter nightime period - the winter
				  nightime ambient noise level (L90), plus the noise level
				  from the proposed new sources modeled as a single value of sound level
				  equivalent to the level of sound exceeded for 10 percent of the time by such
				  sources under normal operating conditions by such sources in a year
				  (L10).
(7)
				  Daytime ambient average noise level - a single value of sound level equivalent
				  to the energy-average ambient sound levels (Leq) during daytime hours (7 am -10
				  pm).
(8) Typical facility noise
				  levels - the noise level from the proposed new sources modeled as a single
				  value of sound level equivalent to the level of the sound exceeded 50 percent
				  of the time by such sources under normal operating conditions by such sources
				  in a year (L50).
(9) Typical future noise level during the
				  daytime period - the energy- average ambient sound level during daytime hours
				  (Leq), plus the noise level from the proposed new sources modeled as a single
				  value of sound level equivalent to the level of the sound exceeded 50 percent
				  of the time by such sources under normal operating conditions by such sources
				  in a year (L50).
