“Due to the operation of the CNG Station, High Level of Sound is created and such level of sound is beyond the permissible limit. There has been constant sound pollution and as a result thereof, the health of the local people have been seriously affected. The local people cannot sleep, cannot take rest comfortably due to the sound pollution. The noise level is certainly beyond the permissible limit. Aged people cannot sleep even at night. Those who are ailing cannot take rest due to the sound pollution. Heart patients are suffering tremendously due to noise pollution. It is necessary to refer to the report prepared by the Tripura State Pollution Control Board in respect to the noise pollution being created due to the operation of the T.R.T.C. CNG Station. Prof. Mihir Kumar Deb, the then Chairman of Tripura State Pollution Control Board, by letter, dated, 16.06.2014, informed the Managing Director, Tripura Natural Gas Company Ltd. that the Noise Level in CNG Station is beyond permissible limit. In the aforesaid letter dated 16.06.2014, the Chairman, TSPCB pointed out that, permissible noise level in residential area is 55 db during day time ( 6 a.m. to 10 p.m. ) and 45 db during night time (10 p.m. to 6 a.m.). It is beyond question that T.R.T.C. area is a residential area and noise created due to the operation of the CNG T.R.T.C. Station is much above the permissible limit. It is also necessary to mention that [the] Chairman Tripura State Pollution Control Board by [the] letter dated 10.10.2013, asked the Managing Director, Tripura Natural Gas Company Ltd. not to run round the clock operation of the Krishnanagar CNG Station.”
