Key Regulation Impact

• Applies to ANMPs filed for 30+ days (consecutive or nonconsecutive)
• Applies to new buildings ≥ 200,000 sq. ft. gross floor area
• Applies to work sites within 50 ft. of residential receptors
• Requires at least one noise monitoring device facing the nearest sensitive or residential receptor
• Devices must collect data throughout construction, until only minimal-noise or interior renovation activities remain. See 15 RCNY 30-102 and 15 RCNY 28-110.

Changes to ANMP Applications

• Must include a map of sensitive & residential receptors as defined in 15 RCNY 28-101 (i) within 75 ft. (via ZoLa NYC's Zoning & Land Use Map)
• Map must show proposed monitor locations
• Application must list number of devices, locations, and responsible party contact info

Noise Monitor Requirements

• Mounted 8-10 ft. off the ground (wall or pole)
• Equipped with outdoor microphone (wind/rain protection, Class 2, IEC 61672-1 compliant)
• Wall-mounted devices must be ≥1 ft. from nearest surface to avoid reflection
• Approved devices will be posted at: nyc.gov/dep

Exemptions

• Construction of buildings where all units are affordable housing as defined in Section 24-223 (e)(1) of the NYC Administrative Code.
• Emergency work as defined in Administrative Code § 24-223(e)(1)

Frequently Asked Questions

Does this rule apply only to new building (NB) construction (i.e., the erection of a new building) or does it apply to all types of construction work requiring an alternate noise mitigation plan (ANMP) that has a gross square footage of 200K and is within 50 feet of residential receptors?

It only applies to new buildings (NB) that meet those criteria.

Are existing projects that have an alternate noise mitigation plan approved prior to the effective date of the new rule "grandfathered" or do these existing projects need to refile their alternate noise mitigation plan showing noise monitors and then install them.

If you already have an ANMP in place, you are not subject to the rule UNLESS you renew it after 4/21/26. You will be required to comply after that date.

Will DEP publish a list of approved monitors before the effective date of the rule (120 days after rule passed)?

The list of approved monitors can be found at Approved Monitoring Devices. Additionally, if a vendor meets the specifications set forth in the rule, and would like to be listed as an approved Monitoring Device, the vendor may contact [email protected] for evaluation.

Is noise monitoring required to be installed and in use until the project completion, even if an ANMP is no longer required for that phase of construction?

The noise monitoring must be done until regardless of whether a subsequent phase requires an ANMP, but can be discontinued at the point when the construction activities taking place at the site have minimal noise impact as set forth in 15 RCNY § 30-102 Chapter 30: Minimal Noise Impact Construction Activities or are limited to interior renovation work, as defined in 15 RCNY § 28-110, Chapter 28: Citywide Construction Noise Mitigation.
