APPENDIX II

  1. Work which requires pile drivers (excluding manual type) and pile extractors and pile driver-extractors (excluding pressure type driver-extractors). Said work does not include that in which pile drivers are used with earth augers.
  2. Work which requires riveting hammers.

  8. Work which requires bulldozers (limited to those with the rated power of the prime mover exceeding 40 kW, excluding those designated by the Director-General of the Environment Agency as not generating noise exceeding a certain limit).
1. Regulatory Standards for Noise Emitted from Specified Factories (Summary)
Time AreaDaytimeMorning
Evening
NighttimeApplicable Areas
I 45 - 50 dB 40 - 45 dB 40 - 45 dB Areas where maintenance of quiet is particularly needed to preserve a good living environment.
II 50 - 60 dB 45 - 50 dB 40 - 50 dB Areas where quiet is needed for as they are used for residential purposes.
III 60 - 65 dB 55 - 65 dB 50 - 55 dB Areas used for commercial and industrial as well as residential purposes where there is a need to preserve the living environment of local residents.
IV 65 - 70 dB 60 - 70 dB 55 - 65 dB Areas mainly serving industrial purposes which are in need of measures to prevent the living environment of local residents from deteriorating.
Note:
Noise level shall be measured at the boundary line of the specified factory.
2. Noise level shall be measured at the boundary line of the specified construction work site.
Type of RestrictionArea ClassifiedPile Driver etc.Riveting HammerRock DrillAir CompressorBatching Plant etc.
Standard valueI & II 85 dB
Work prohibited timeI 7 p.m. - 7 a.m.

Notes:
  1. 'Area I' stands for areas to which one of the following descriptions applies:
    • (1) Areas where maintenance of quiet is particularly needed to preserve the residential environment.
    • (2) Areas which require maintenance of quiet since they are used for residential purposes.
    • (3) Areas used for commercial and industrial as well as residential purposes which are in need of measures to prevent noise pollution since a considerable number of houses are located.
    • (4) The neighborhood of schools, hospitals and the like. 'Area II' stands for areas where there is a need to preserve the living environment.
  • Noise level shall be measured at the boundary line of the specified construction work site.
