1. These rules may be called the Environment (Protection) second Amendment Rules, 2002.
2. They shall come into force on the date of their publication in the Official Gazette.

2. In the Environment (Protection) Rules, 1986 (herein after referred to as the said rules), in Schedule I, ?

1. against serial number 47, item (d) relating to Diesel generators for domestic purposes and the entries relating thereto shall be omitted;
2. serial number 83 relating to standards/Guidelines for control of noise pollution from Stationary Diesel Generator(DG) sets and the entries relating thereto shall be omitted;
3. after serial number 93 relating to Primary Water Quality Criteria for Bathing Waters and the entries relating thereto, the following serial numbers and entries shall be inserted, namely:-

1. Noise limit for diesel generator sets (upto 1000 KVA) manufactured on or after the 1^st July, 2003.
The maximum permissible sound pressure level for new diesel generator (DG) sets with rated capacity up to 1000 KVA, manufactured on or after the 1^st July, 2003 shall be 75 dB(A) at 1 metre from the enclosure surface.
The diesel generator sets should be provided with integral acoustic enclosure at the manufacturing stage itself.
The implementation of noise limit for these diesel generator sets shall be regulated as given in paragraph 3 below.

2. Noise limit for DG sets not covered by paragraph 1.
Noise limits for diesel generator sets not covered by paragraph 1, shall be as follows:

1. Noise from DG set shall be controlled by providing an acoustic enclosure or by treating the room acoustically, at the users end.
2. The acoustic enclosure or acoustic treatment of the room shall be designed for minimum 25 dB (A) insertion loss or for meeting the ambient noise standards, whichever is on the higher side (if the actual ambient noise is on the higher side, it may not be possible to check the performance of the acoustic enclosure/acoustic treatment. Under such circumstances the performance may be checked for noise reduction upto actual ambient noise level, preferably, in the night time). The measurement for Insertion Loss may be done at different points at 0.5 m from the acoustic enclosure/room, and then averaged.
3. The DG set shall be provided with proper exhaust muffler with insertion loss of minimum 25 dB(A).
4. These limits shall be regulated by the State Pollution Control Boards and the State Pollution Control Committees.
5. Guidelines for the manufacturers/users of Diesel Generator sets shall be as under:
   1. The manufacturer shall offer to the user a standard acoustic enclosure of 25 dB(A) insertion loss and also a suitable exhaust muffler with insertion loss of 25 dB(A).
   2. The user shall make efforts to bring down the noise levels due to the DG set, outside his premises, within the ambient noise requirements by proper siting and control measures.
   3. Installation of a DG set must be strictly in compliance with the recommendations of the DG set manufacturer.
   4. A proper routine and preventive maintenance procedure for the DG set should be set and followed in consultation with the DG set manufacturer which would help prevent noise levels of the DG set from deteriorating with use.
