Braintree City Zoning Code
ARTICLE XI
Environmental Performance Standards
§135-1101 Establishment of standards.
Any use permitted by right or special permit in any district shall not be conducted in a manner as to emit any dangerous, noxious, injurious or otherwise objectionable fire, explosion, radioactivity or other hazard, noise or vibration, smoke, dust, odor or other form of environmental pollution; electrical or other disturbance; glare; liquid or solid refuse or wastes; conditions conducive to the breeding of insects or rodents; or any other substance, condition or element in an amount as to affect adversely the surrounding environment. The following standards shall apply:
A.
Emissions shall be completely and effectively confined within the building or so regulated as to prevent any nuisance, hazard or other disturbance from being perceptible, without the use of instruments, at any lot line of the premises on which the use is located.
B.
All activities and all storage of flammable and explosive materials at any point shall be provided with adequate safety devices against fire and explosion and adequate fire-fighting and fire-suppression devices and equipment, as approved by the Chief of Fire Department.
C.
No activities that emit dangerous radioactivity at any point, no electrical disturbance adversely affecting the operation at any point of any equipment, other than that of the creator of such disturbance, shall be permitted.
D.
No air emission shall be permitted except in accordance with the regulations for the control of air pollution in the Metropolitan Boston Air Pollution District under MGL c. 111, § 142D.
E.
No emission which can cause any damage to the health of animals or vegetation or which can cause excessive soiling at any point, and in no event any emission of any solid or liquid particles in a concentration exceeding 0.5 milligram per liter or parts per million of conveying gas or air shall be permitted.
F.
No discharge, at any point, into a private sewer system, stream, the ground or a municipal sewage disposal system of any material in such a way or of such a nature or temperature as can contaminate any running stream, water supply or otherwise cause the emission of dangerous or objectionable elements and accumulation of wastes conducive to the breeding of rodents or insects shall be permitted.
G.
No emissions of odorous gases or odiferous matter in such quantities as to be offensive shall be permitted. Any process which may involve the creation and/or emission of any odors shall be provided with a secondary safeguard system. No objectionable odor greater than that caused by 0.001202 per thousand cubic feet of hydrogen sulfide or any "odor threshold" as defined in Table III in Chapter 5 of Air Pollution Abatement Manual, copyright 1951, by Manufacturing Chemists Association, Inc., of Washington D.C., shall be permitted. No direct sky-reflected glare, whether from floodlights or from high-temperature processes such as welding, shall be permitted.
§135-1102 Noise and vibration control.
Purpose. Pursuant to the authority conferred upon the Town by MGL c. 40, § 21, the following is adopted for the regulation and restriction of unnecessary, excessive and annoying noise and vibration in the Town of Braintree. It is declared to be the policy of the Town of Braintree to prohibit such noise and vibration from or by all sources as set forth in this bylaw. Because it has been determined that certain noise levels and vibrations are detrimental to the public health, welfare, safety and convenience as well as contrary to the public interest, these standards have been set forth by the Town of Braintree to declare that creating, maintaining, causing or allowing to be created any noise or vibration in a manner prohibited by or not in conformance with these standards is a public nuisance punishable as set forth in this bylaw.

§135-1105 Sound levels by receiving land use.
A.
Except as provided in § 135-1106, no person shall operate or cause to be operated any source of sound in a manner that creates a sound level which exceeds the ambient noise level set forth for the receiving land use category in the following table when measured at or within the property boundary of the receiving land use.
Receiving Land Use Category | Item | Sound Level Limit (DBA) | |
|---|---|---|---|
Residential A, B and C | Daytime | 60 | |
Open space | All other times | 50 | |
Business | At all times | 65 | |
Commercial | At all times | 70 |
B.
No person shall sell or rent, or cause to be sold or rented, any structures or property to be used for human habitation where the structure or property is exposed to sound levels which are for 50% of the time in excess of the standards set forth in this bylaw without written disclosure of said condition. The Board of Selectmen shall develop a standard format for these written disclosures.
§135-1106 Restrictions on noise emitted from construction sites.
A.
Except as provided in § 135-1104B, it shall be unlawful of any person to operate any construction device on any construction site if the operation of that device emits noise measured at the lot line of the affected property in excess of the following values:
Use of Affected Property | L 10 Level | Maximum Noise Level | ||
|---|---|---|---|---|
Residential A, B and C | 75 DBA | 86 DBA | ||
Business | 80 DBA | — | ||
Commercial | 85 DBA | — | ||
Public way | 85 DBA | — |
B.
The L 10 level shall be determined by making 100 observations on the A-weighted network with the sound-level meter at slow response at ten-second intervals. During any of these observations if a measurement is substantially affected by a source outside of the construction site, these measurements will not be considered. Observations will be continued until 100 valid observations have been recorded. The L 10 level will be equivalent to the 10th highest level recorded.
If the person taking measurements estimates that outside noise sources contribute greatly to the noise of the construction site, the aforementioned procedure shall be repeated when construction is inactive in order to correctly determine the L 10 level. The L 10 level during construction must be greater than the background L 10 level by at least five DBA to be considered in violation of the provisions of this regulation. |
§135-1107 Motor vehicles and motorcycles on public rights-of-way.
No person shall operate or cause to be operated a public or private motor vehicle or motorcycle on a public right-of-way at any time in such a manner that the sound level emitted by the motor vehicle or motorcycle exceeds the following limits. Motor vehicle and motorcycle sound limits to be measured would be at a distance of 50 feet or approximately 15 meters from the center line of travel.
Sound level in DBA | ||
|---|---|---|
Vehicle Class | Speed Limit 35 mph or Less | Speed Limit Over 35 mph |
Vehicles in excess of 10,000 pounds engaged in interstate commerce as permitted by 40 CFR 303, Environmental Protection Agency(Noise emission standards for motor vehicles engaged in interstate commerce) | 86 | 90 |
All other vehicles of 10,000 pounds or more | 86 | 90 |
Any other motor vehicle or combination of vehicles towed by any motor vehicle | 78 | 82 |
