The Middlesex County Environmental Health Division (MCEHD) is authorized by the New Jersey Department of Environmental Protection (NJDEP) to enforce noise pollution regulations as established in the State Noise Pollution Code.  The MCEHD enforcement authority for noise pollution was established by an interagency agreement signed in April 1993, pursuant to the County Environmental Health Act (CEHA).  The State Noise Pollution Code, under NJAC 7:29, establishes specific maximum day and nighttime noise levels from sources such as industrial, commercial, and public service facilities, as well as standards for conducting noise investigations and for assessing penalties.
Additionally, the Noise Pollution Program will assist towns with drafting and enforcement of municipal noise codes.  Municipal codes must be approved by the NJDEP in order to be valid.  The ordinance must include noise standards for residential, as well as industrial and commercial sources.  Presently, ten towns have NJDEP approved noise codes.
The NJDEP and Rutgers Noise Technical Assistance Center published a revised Municipal Model Noise Code in 1997.  Municipalities may adopt the new model code as written or modify it, subject to NJDEP approval.  However, they should consult with the Noise Program before adopting or amending their noise codes.  An information packet is available to assist them with this endeavor.
