Note: The soil values are calculated 
for a ‘Standard Soil’ with 10% organic matter 
and 25% clay. A case of environmental contamination is defined as ‘serious’ if >25 
m³ soil or >100 m³ groundwater is contaminated above the intervention value. 
 
Source: Soil Remediation Circular 2009, Annex 1: Groundwater target values and 
soil and groundwater intervention values. (*Target values for soil refer to 2000 
version as they are not present in the 2009) 
 
Where contaminants are found to exceed ‘intervention’ levels, this is considered to 
be a case of soil contamination, which is dangerous to the health of humans and 
the natural environment. Such a level of contamination should prompt a need for 
remediation, appropriate treatment and disposal.

National Requirements
 
Resolution of 
Cabinet of Ministers of Republic of Uzbekistan No.95 “On approval of 
general technical regulations of environmental safety” (2020). 
Requires the implementation of environmental safety measures for the 
protection of flora and fauna. This includes the prevention of death of wildlife 
species due to magnetic fields of power transmission lines and sanitary 
protection zones. 
Requires transformer substations in power transmission lines, their grids to have 
equipment (barriers, fences etc.,) to prevent animals from entering the territory 
of the substation. 
 
Decree of the Cabinet of Ministers of the Republic of Uzbekistan No.1050 “On 
approval of Rules for Protection of Power Grid Facilities, 2018”.

This determines the procedure for establishing protected zones for power grid 
facilities, as well as special conditions for using land located within the 
protected zones and ensure the functioning and operation of the said facilities. 
Construction of power grid facilities with 110, 220 or 500kV in protected areas of 
state nature reserves, protected areas of nature parks and state biosphere 
reserves etc shall be allowed with the permission of the Cabinet of Ministers of 
the Republic of Uzbekistan. 
Protected zones of power grid facilities shall be established on both sides of the 
power transmission line from the outermost wires and along the perimeter of 
substations at the following distances for voltages; 
o
110kV: 20 meters; 
o
220kV: 25 meters; and
o
500kV: 30 meters. 
 
San Rules & Norms No. 0236-
07 “Sanitary norms and rules to ensure safety for 
people living near high voltage power transmission lines, 2007”. 
This regulation sets the requirements for ensuring public safety when overhead 
power lines pass over populated, unpopulated or inaccessible territories.
It requires sanitary norms and rules to be followed in the design, construction 
and operation of overhead power lines. 
The distances corresponding to the projection onto the ground of the outer 
phase wires in a direction perpendicular to the overhead line as follows: 
o
Up to 110kV/m: 10 meters; 
o
Up to 220kV/m: 15 meters;
o
Up to 330kV/m: 20 meters; 
o
Up to 500kV/m: 30 meters; and
o
Up to 570kV/m: 40 meters. 
In addition, SanPin 0236-07 specifies that EMF in population living areas is not to exceed 
1.0kV/m and magnetic fields 80 A/m (equivalent to 100 138
μ
T). 
5.5.2 
Lenders Requirements
EBRD 
EU Council Recommendation 1999/519/EC on the limitation of exposure of the general public 
to EMF (0 Hz to 300 GHz) references and recommends ICNIRP derived limits as applicable 
“when the time of exposure is significant” that is the limits should apply to “areas where 
members of the public spend significant time in relation to the effects covered by this 
recommendation”.
