Environmental protection

The project for the construction of the auxiliary management services building of Belpromstroybank OJSC on Lenin Avenue in Gomel was developed by the Gomelproekt Institute on the basis of architectural and planning task No. 57 on 04/04/01. and decisions of the City Executive Committee No. 283 § 7 of 05.03.2001.

The estimated cost of construction is 3643.56 thousand rubles, including 1.8 thousand rubles for environmental protection measures.

The project provides for the new construction of the Belpromstroybank auxiliary management services building and the development of environmental protection measures in connection with the presence of pollutants from garages and guest sites.

The designed object is located in the area of ​ ​ multi-storey buildings at Gomel, pr. Lenin, 31. The designed building is a three-story building with an attic floor and a basement, connected with the existing building by a passage on the second floor. There are no protected areas at the facility. The approximate area of ​ ​ the section is 0.12 ha.

On the ground floor of the designed building, a heated parking lot for three cars and a heated box for a collection machine are designed. On the territory of the designed bank, two guest parking lots of 10 cars are provided (one next to the bank, the second on Krestyanskaya St.). All these are sources of pollutant release.

The bank operates 253 days a year in the usual single-shift mode. Working time fund - 2024 h. Bank heating - centralized from the designed heating networks. Centralized heat supply is one of the most effective methods of environmental protection.

The list of pollutants emitted by sources of atmospheric air pollution, their maximum permissible concentrations, emission volumes and hazard categories for each ingredient and object as a whole are given in the table "List of pollutants emitted into the atmosphere" (section of the environmental protection system).

Calculation of the dispersion of harmful substances was carried out on PC using the Ecologist program.

Analysis of the calculation results taking into account the performed measures showed that for all ingredients and the summation group there is no excess of surface concentrations of more than 1 MPC at the border of the settlement zone. Printouts of scattering maps are given in the section of Environmental Protection.

The project provides for the improvement and landscaping of the territory. Improvement provides for asphalting of entrances, tile construction of footpaths.

Surface water from the territory of Belpromstroybank OJSC is formed as a result of precipitation. On the designed site, a closed rainwater sewage system is provided with the diversion of surface water to it along the planned terrain.

Household wastewater from Belpromstroybank OJSC by gravity enters the existing network of the city.

The total water consumption and drainage of the facility is 1.99 m3/day.

Landscaping includes the creation of 167m2 lawns (see sheet 3, section GP).

Under the spot of the construction of a guest parking lot on the street. Peasant falls 2 (two) trees to be demolished (see the Act of the Commission for Demolition of April 9, 2002. and order of the administration of the Central District No. 99 of 10.04.02)

14 ( fourteen) trees fall under the building construction spot (see page 60 of the general explanatory note), which are also subject to demolition (see Demolition Commission Act of

and order of the administration of the Central District No. dated 02/02).

Construction debris formed during the construction of the object in the amount of 148.6 tons. temporarily stored on site for storage (see sheet 1, OS section), and then taken to landfill in n. Wrestling (driving range 51km.). Soil formed during the construction of the facility in the volume of 3216t. exported to construction sites of the city and to backfill economically unnecessary reservoirs.
