NYC DEP Approved
Noise Monitoring

The DEP has made it clear, the responsibility is on the developer to monitor noise levels. If you are a:

• General Contractor
• Construction Manager
• Developer
• Environmental Consultant

…working on large NYC projects, this regulation applies to you.

Your new project must comply if ALL of the following apply:

• Requires an Alternative Noise Mitigation Plan (ANMP)
• Construction lasts 30 days or more (consecutive or not)
• Building size is ≥ 200,000 sq. ft.
• Work occurs within 50 feet of a residential receptor

If these conditions are met, you must install at least one noise monitoring device on-site.

The DEP has made it clear, the responsibility is on the developer to monitor noise levels. If you are a:

1. Continuous, 24/7 Monitoring
   • Monitoring must run throughout construction
   • Can only stop when work is limited to interior or minimal-noise activities
2. Device Placement & Setup
   • Installed 8–10 feet above ground
   • Positioned facing the nearest residential or sensitive receptor
   • Wall-mounted devices must be ≥1 ft. from nearest surface to avoid reflection
   • System must include
   • Outdoor-rated microphone with wind and rain protection
   • Weather-protected enclosure
   • Minimum of IEC 61672-1 Class 2 compliance
3. Data Collection & Reporting
   • Measure sound in A-weighted decibels (dBA)
   • Capture Lmax levels in 5-minute intervals
   • Transmit time-stamped data at least hourly to DEP

Your submission must now include:

• Map of receptors within 75 feet
• Monitor locations
• Number of devices
• Responsible party info

NYC DEP has published a list of approved monitoring devices. Larson Davis’ Environmental Monitoring Systems for Noise Model EMS011 is included on this list as an approved monitoring device.

Devices must meet all technical and reporting specifications defined in the rule.

The Environmental Monitoring System Model EMS011 from Larson Davis is designed specifically for continuous environmental noise monitoring in demanding urban construction environments.

Why Model EMS011 is Built for NYC DEP Compliance

• Designed for continuous, unattended monitoring
• Class 1 system ensures accuracy and defendable data
• Includes outdoor microphone with weather protection
• Real-time data logging, storage, and transmission
• Supports required metrics (dBA, Lmax, time history)
• Cloud-connected reporting aligned with DEP data expectations
• Flexible power options (line or solar)

Model EMS011 meets and exceeds the specifications required by NYC DEP and is approved for use under the new rule and is specifically named as an approved device.

April 21, 2026 marks the start of enforcement. Delays in implementation can lead to:

• ANMP approval issues
• Project delays
• Increased scrutiny from DEP

Unlike handheld meters or temporary setups, the EMS011 is engineered for:

• Long-term outdoor deployment
• Harsh jobsite environments
• Reliable, uninterrupted operation
• Remote access for compliance documentation
