Hot Spots Subject to Quantitative Assessment

4.2. Hot Spots Subject to Quantitative Assessment

The preliminary selection of Hot Spots having direct discharge to surface water bodies was based on the method of “effective mass of pollutant” (Chapter 3, Methodology).  Hot Spots with the highest scores of “effective mass of pollutant” were subject to a subsequent evaluation (Step 2) for the purposes of a more detailed assessment.

Data with regard to the volume of discharges of pollutants specified to the individual parameters of discharge (mi) are available in the national statistics database (2TP- “Water Industry”).  The values of the maximum allowable concentration (MAC) for the various components were considered to be the normatives of the former Ministry of Fish Industry of the USSR “Combined List of Maximum Allowable Concentrations and Tentatively Safe Levels of Influence (TSLP) of Pollutants on the Water Bodies of the Fish Industry”, Moscow, 1990.  The list of parameters for calculation of the effective mass of pollutants (Table 4.2) was mutually agreed upon with the National Experts of the Ukraine, Belarus and Russia.

The values of effective mass of pollutants of the individual Hot Spots were used as quantitative indices for the preliminary screening and classification of the selected Hot Spots.

Table 4.2 includes the list of parameters used for the calculation of the effective mass of pollutants.

The calculation of the total effective mass of pollutants discharged was determined for 40 enterprises for the years 1995 and 2001.  The results of the calculation of the effective mass of the contaminants discharged enabled the ranking of these enterprises according to a descending sequence in terms of the amount of pollution (Table A-1, Annex A).

In this way, during the first stage of activity the experts identified the list of sources of pollution (Hot Spots) located in the Dnipro River basin within the territory of the Russian Federation for 2001.  During the second stage, the preliminary list of Hot Spots was reduced to fifteen (15) sites, where fourteen (14) Hot Spots had the highest effective mass of pollutants discharged for the period 1995-2001 and one (1) Hot Spot was an agricultural (mainly cattle-breeding) complex located in the basin of a transboundary water body, that is, the Vorsklitsa River.  This Hot Spot is included for detailed evaluation as a result of a systematic exceedance of the maximum allowable concentration of a number of contaminants in the Vorsklitsa River at the border of the Russian Federation and Ukraine.

The list of Hot Spots selected during the first stage, according to the highest indices of effective mass of pollutants discharged (Mx) as well as the results of expert assessment is given below in Table 4.3.

 Hot Spots Located in the Dnipro River Basin (within the Russian Federation) Selected for Detailed Analysis

The fifteen (15) Hot Spots are represented by the following types of facilities:

11- utility enterprises;

2 –chemical industry enterprises;

1 –power industry enterprise;

1 – agricultural complex.

A detailed assessment and prioritization of the Hot Spots was conducted by means of scoring in accordance with the accepted methodology (Chapter 3).  Four areas of interest were determined as categories in the estimation procedure, in particular:

- Pollution control;

- Quality of water and human health;

- Environment and biodiversity;

- Economy.

The categories are subdivided into subcategories.  In turn, the subcategories consist of numerous indices, called criteria.  The scores were carried over to the summed table of scores to calculate a total score for every Hot Spot after specification of their weighting factor.

The National Experts completed scoring sheets for every one of the selected 15 Hot Spots based on the data available at national and regional centres.
