Krasnodar GRES Project Volume I11 Environmental Assessment

Reference points 002 through 004 are located on the development territory at
the closest distance to the industrial site.
For the purposes of these estimates, the following assumptions were made:
Noise propagation from sources is direct through air.
There are no noise shields or other obstacles between industrial site and
development territories.
Table 5.9 is representative of expected acoustic pressure levels in reference points
caused by individual noise sources (RoTEP estimates).

1. Most unfavorable combination of existing noise sources with 6 gas units
operating at full capacity and exhaust from the stack 1= 150 m.
2. Calculation of acoustic pressure levels caused by ~0-4 (NS), as an
emergency source, was calculated separately.
Conclusions: Expected acoustic pressure levels in all reference points exceed the
permissible values mainly due to noise sources ED-1 (NS) and ~0-2
(NS).
Table 5.10 is representative of calculation of required acoustic pressure level
decrease in reference points (Lst = L-Lb).
