INSTALLATION COMPATIBLE USE ZONE STUDY
An Installation Compatible Use Zone (ICUZ) study provides a strategy for noise management in the areas surrounding a military facility. Elements of the ICUZ include military noise analysis, noise background and metrics, complaint management, and when necessary, noise abatement procedures. The ICUZ study examines noise exposure associated with military testing/training operations, and provides land use guidelines for achieving compatibility. The ICUZ can assist both installation personnel and local government officials.
The Environmental Noise Branch can assist in all aspects of military noise analysis for compliance with National Environmental Protection Act (NEPA) requirements. Services include range and aircraft noise modeling, development of noise assessment reports for existing activities and proposed alternatives, and review of noise specific sections in Environmental Assessments (EA) and Environmental Impact Statements (EIS).
The Noise Branch has expertise in DoD approved computer based noise models for aircraft, small arms, and large caliber weapons (including explosive charges). Noise contours are used to evaluate land use compatibility and determine audibility/complaint risk of existing and proposed operations.
The Environmental Noise Branch can assist Army and other DoD personnel with information and/or document review for matters pertaining to noise generated by military training and operations. This can include information and/or document review for Army Compatible Use Buffer and Compatible Use Plan (formerly Joint Land Use Study) development, as well as guidance on using contouring to establish priority areas and Military Compatibility Areas (MCA). Additionally, the Noise Branch can offer information regarding aspects necessary for developing effective and comprehensive Noise Management Programs.
Although noise modeling is the primary means of assessing environmental noise impacts, the Environmental Noise Branch has the expertise and equipment to conduct on-site noise monitoring. Monitoring can offer valuable information regarding specific noise levels, when the source or operations cannot be modeled or in instances when recorded data are used as a community relations tool.
Traditional training opportunities for 'military' Environmental Noise are generally limited. However, there are resources available online, such as webinars produced by
REPI which provide an introduction to noise, and a variety of other topics including JLUS, Natural Resources, Sentinel Landscapes, and TE&S.

Fact Sheets/Tip Sheets
• DoD Operational Noise Program. Established policy and assigns responsibilities for a coordinated DoD noise program. It also provides for establishment of a DoD Noise Working Group (DNWG).
• Title 40, Chapter V, CFR Part 1500-1508 – National Environmental policy Act (NEPA). Federal law that requires the review of all federally supported activities that have the potential to impact the environment.
• AR 200-1 Environmental Protection and Enhancement Chapter 14 contains policy to develop, implement, and maintain noise programs that promote long-term compatible land use on and in the vicinity of Army installations.
