Industrial noise in Nashua is regulated through Chapter 201 (Noise) - the disturbance / 50-foot audibility standard - layered with Chapter 190 (Land Use Code) industrial-performance standards and the Chapter 128 residential-zone construction-equipment quiet window (8 p.m. - 7 a.m. weekdays; no Sunday/holiday). NH RSA 644:2 disorderly conduct is the statewide backstop. New Hampshire has no statewide environmental noise dB code (unlike WAC 173-60). Active industrial concentrations include the Sundial Avenue and Crown Street industrial parks, the Daniel Webster Highway south light-industrial corridor, the Amherst Street rail-served sites, and the former mill complexes along the Nashua River (many now in adaptive-reuse mixed-use redevelopment).

Nashua FAQ
Are there decibel limits for industrial sites in Nashua?
Nashua does not codify a numeric dBA matrix for industrial source noise. Unlike Washington (WAC 173-60) which sets statewide caps, New Hampshire has no statewide environmental noise dB framework. Industrial noise is regulated by (1) Chapter 201 (Noise) - the disturbance / reasonableness standard (fine not less than $100); (2) Chapter 190 (Land Use Code) industrial-performance standards requiring noise/vibration/emissions be controlled so as not to be detrimental or cause a nuisance to nearby residential or commercial areas; (3) Chapter 128 (Construction and Demolition Work) - construction-equipment operation in residential zones or within 600 feet of any dwelling barred 8 p.m. - 7 a.m. Sun-Fri, 7 p.m. Sat - 8 a.m. Sun, and all day Sundays / holidays. NH RSA 644:2 disorderly conduct is the statewide backstop.
What about noise from rail and the F.E. Everett Turnpike through Nashua?
Pan Am Railways / CSX rail operations through Nashua (along the Nashua River corridor and East Hollis Street) are federally preempted under the Interstate Commerce Commission Termination Act (49 U.S.C. 10501(b)) - the city cannot cite rail operations for noise. The F.E. Everett Turnpike / U.S. Route 3 corridor is administered by the New Hampshire Department of Transportation under federal noise-abatement criteria at 23 CFR 772.
