Minnesota Administrative Rules
7030.0040 NOISE STANDARDS.
Subpart 1. Scope. These standards describe the limiting levels of sound established
on the basis of present knowledge for the preservation of public health and welfare. These
standards are consistent with speech, sleep, annoyance, and hearing conservation
requirements for receivers within areas grouped according to land activities by the noise
area classification (NAC) system established in part 7030.0050. However, these standards
do not, by themselves, identify the limiting levels of impulsive noise needed for the
preservation of public health and welfare. Noise standards in subpart 2 apply to all sources.
§ Subp. 2. Noise standards.
