In the East Kazakhstan region the large enterprises of mining industry and nonferrous metallurgy are concentrated. From Soviet Union the Republic of Kazakhstan inherited the industrial giants with worn out processing equipment and with backward technology.
Total emission of polluting substances on VKO in 1990 made up 345,5 thousand tons.

Industrial cities of the region, such as Ust-Kamenogorsk, Ridder, Glubokoe settlement were considered as ones of the most polluted cities not only in Kazakhstan, but in the USSR.
Under scheduled system of the USSR the increase of enterprises output were first of all without taking into account the influence on atmospheric air conditions and health of the population. Thus annually plans of output increased at the same available capacities of process equipment that led to overloads, premature deterioration, frequent emergency stops of technological and dust-gas collecting equipment. Due to the lack of gas purification reserve systems at their emergency stops metallurgical plants continued to work polluting the atmosphere.

Industrial cities of the East Kazakhstan region, in particular Ust-Kamenogorsk, occupied the leading position on atmospheric air pollution. Ust-Kamenogorsk is a large industrial and science centre at its enterprises it is produced lead, zinc, titan, magnesium, sulfuric acid, noble and rare metals, mining equipment and other production. According to the East Kazakhstan regional statistics administration in Ust-Kamenogorsk it is registered 3217 organized and 2484 unorganized stationary sources.

In this situation the East Kazakhstan regional territorial administration of environment preservation takes a strict position regarding enterprises - nature managers, applying all lawful tools and levers of influence on environment pollutants. As a result the volumes of total emissions from stationary sources noticeably decreased.

Emission dynamics of polluting substances in Ust-Kamenogorsk city

Decrease of emissions of polluting substances is caused, first of all, by implementation of ecological programs regarding protection of atmospheric air at the city enterprises.

So, in 2004 with the purpose of emission reduction of harmful substances in atmospheric air on Ust-Kamenogorsk site of "Kazzinc"JSC it was put into the operation «Haldor Topse» plant on recycling of agglomerating and roaster gases that will utilize up to 40 % of emissions of sulphurous gas. Expenses for realization of «Haldor Topse» technology made up 4,4 billion tenge. The analysis of dynamics of atmosphere pollution in Ust-Kamenogorsk city on controllable posts of VK hydrometeorology center shows, that the last years, before installation of «Haldor Topse», daily average concentration of sulphurous anhydride in Ust-Kamenogorsk made up 2,6 maximum concentration limits. After installation of «Haldor Topse» daily average concentration of sulphurous anhydride on Ust-Kamenogorsk made up 1,3-1,8 maximum concentration limits, and maximal single concentration made up 0,2-0,6 maximum concentration limits.

At the same time, decrease of polluting substances emission is also caused by achievement of maximum permissible level of emission at such large enterprises, as «UK TMK»JSC, "UMZ"JSC, «Condenser zavod»JSC, "VostokMashzavod"JSC. Besides reconstruction of sulfuric acid plant and closing of calcining plant of UK MK “Kazzinc”JSC, and also closure of the Irtysh copper-smelting factory all these measures led to significant reduction of sulphurous anhydride emission.

«АЕS UK TES»JSC according to the Program of measures on environment preservation and rational use of natural resources, the Memorandum between AES company and the Ministry of environment preservation of RК, the following measures were implemented:
- development of the project and reconstruction steam generating unit BKZ 320-140 article 12 with the purpose of decrease of emissions nitrogen oxide;
- installation of highly effective dust extraction plants

In 2006 «AES Ust-Kamenogorsk TES» is planned to continue the actions on decrease of emissions of firm particles and nitrogen oxide.

At the same time, «AES Ust-Kamenogorsk TES» JSC is not yet certified according to the international standards, in particular on management system on environment preservation. The technological level of «AES Ust-Kamenogorsk TES» JSC doesn’t meet the requirements of the «Strategy of entering of Kazakhstan in number 50th the most competitive countries of the world» in the field of environment preservation.

Measures on environment preservation should stimulate the creation of production with the newest technologies and reconstruction of the existing enterprises.

Emission in atmospheric air from stationary sources in Ust-Kamenogorsk for 2005
1. Emissions of nitrogen oxides (90,79 %), firm polluting substances (89,9 %), sulphurous anhydride (18,69 %) from stationary sources of atmosphere pollution in Ust-Kamenogorsk are caused by emissions of power system.
2. Emissions of nitrogen oxides (8,5 %), firm polluting substances (8,1 %), sulphurous anhydride (81,0,9 %) from stationary sources of atmosphere pollution in Ust-Kamenogorsk are caused by emissions of nonferrous metallurgy.

Substances polluted the atmospheric air in Ust-Kamenogorsk city:
Table №2

Tables №1-2 show, that from 5 substances the influence of nitrogen oxides and weighed substances caused by emissions of power system and including emissions of «AES Ust-Kamenogorsk TES» JSC predominates.

Last years position has become complicated in city because of sharply increase of influence of motor transport on atmosphere of city. The quantity of motor transport annually increases. Statistics shows, that it is annually registered from 2 up to 3 thousand vehicles in city. In 2004 there were 47 118 motor cars and 8 820 lorries (total 55 938 units) in the city. In 2005 there are more than 50 000 cars in the city.

Negative influence of motor transport on atmosphere of the city is especially seen in August - September. Especially, when there is the period of difficult atmospheric conditions. VK regional territorial administration of environment preservation realizing the negative influence of atmospheric air conditions on health of the population initiated the conducting of three researchers: «Complex geoecological research of the territory of Ust-Kamenogorsk city and health of the population», «Studying of chemical composition of atmosphere of Ust-Kamenogorsk city» and «Modeling of influence of motor transport on atmosphere of Ust-Kamenogorsk city».

The first results of these works are received. Results of work on chemistry of Ust-Kamenogorsk atmosphere confirmed the theory of significant role of motor transport in atmosphere pollution of the city.

The problem of ecological improvement of internal combustion engines (ICE) of motor transport was and remains one of the most important and not realized by our society and unresolved state problems of national country safety. It is established that it is motor transport by its toxic exhaust gases pollutes the atmosphere of cities and does a considerable, escalating harm to health of people and nature.

Problems available on today can be solved in the future. As above stated, the decision of problems connected with use of motor transport, is decided by production at industrial enterprises inexpensive cleaners of exhaust gases (catalytic neutralizers) and their installation on city vehicles that in some way solves the problem of atmospheric air pollution by exhaust gases.

Development and realization of the complex program of transport ecological safety provision at support of the state will inevitably lead to disposal us and our descendants from toxic "plague" of the XXI century.

It should be noted, that in spite of the fact that enterprises carry out the measures on emission decrease of polluting substances during the periods of difficult atmospheric conditions according to projects PDV, and under long-term difficult atmospheric conditions the accepted measures are appeared to be insufficient, there is accommodation of polluting substances in atmospheric air, a threat of extreme high level of atmosphere pollution in the city. There was a case of full stop of lead factory UK MK “Kazzinc” JSC for prevention of extreme high level of atmosphere pollution and by that the rights of nature managers were broken.

For decision of problems concerning atmospheric air conditions in days of difficult atmospheric conditions it is necessary to develop and commission the legal acts to nature protection laws according to requirements of the law «On normative legal acts». Till now there are no methodical instructions on regulation of emissions during
