When carrying out finishing (finishing and lapping) operations necessary for the manufacture (repair) of products of transport pipeline systems, special attention is paid to the auxiliary materials necessary for the imple-mentation of this technological process. The basis of these materials are chemically active, surfactant, flammable and explosive substances of organic and inorganic origin, developed according to a certain recipe in a strict combination of ingredients and with high requirements for quality output. During the implementation of the technological process of manufacturing or repair of products of transport pipeline systems, the auxiliary material is often considered as a kind of random process that has a certain impact on the environmental safety of these systems. This material for technological purposes is characterized by a num-ber of indicators that do not have numerical values, but to interpret them it is necessary to build a system of logi-cal and analytically related relationships, taking into account the required formulation of auxiliary material. In practice, these indicators of the material represent some criterion (criteria), which in the n-dimensional space can be represented as a vector of the technological state of the auxiliary material on the basis of its integrated evalua-tion. At present, a general scheme of work on the automated design of the formulation of auxiliary material based on the aggregate design method has been developed. The task of this method is to give the developed auxiliary material the maximum potential energy, as well as to increase its shelf life and reduce the risk of environmental impact. In addition, there are certain requirements for the ingredients of the material, and the formulation of the auxiliary material is based on the use of such ingredients that would ensure the reliability, quality and environ-mental safety of the operation of transport pipelines.

Ensuring technogenic and environmental safety of transport pipeline systems is a complex state task. The main group of reasons leading to failures, accidents and other incidents in these systems is associated with the quality of manufacture (repair) of equipment, as well as the level of operation of transport pipeline systems. At the present stage of transport pipeline systems development, the design-technological approach, including the maintenance and repair of valves, is significantly changing. Particular attention is paid to the abrasive finishing and lapping treatment, which allows, in one operation, carrying out first the roughing (allowance removal), and then the final finishing with achievement of the shape and dimensional accuracy of the workpiece. The proposed calculated dependences allow predicting the operation reliability and durability of high-precision products of transport pipeline systems valves and, thus, increase the level of environmental safety of transport pipeline systems.

The features of information support between different agencies in emergency situations in a number of countries, including in Ukraine, are investigated in the paper. Insufficient level of modern legal basis for ensuring information exchange between different agencies in case of emergency environmental situations is noted. There is a lack of common approaches to the role of emergency environmental situations in Ukraine's civil protection system. The necessity to investigate the distribution of responsibilities of the monitoring entities and their ability to conduct operational environmental monitoring to determine the information interaction between central, local and environmental authorities in monitoring emergency environmental situations was noted. The organization of interaction of units of the State Emergency Service of Ukraine with nature protection bodies in case of emergency environmental situations, organization of interaction between structural units of Ministry of Ecology and Natural Resources of Ukraine and central and local executive authorities is proposed. The scheme of information interaction of Ministry of Ecology and Natural Resources of Ukraine and the central and local executive authorities in conducting environmental monitoring in emergency environmental situations is proposed, which provides information through two channels - through regional state administrations and central executive authorities. It takes into account the need for a joint exchange of information between the State Emergency Service of Ukraine and Ministry of Ecology and Natural Resources of Ukraine for a timely response to potential and actual threats and the adoption of the relevant parts of the State Emergency Service of Ukraine measures for the prevention of emergencies and reduce their consequences. The reliability of the results of processing the received information is ensured by the implementation of the requirements of the unified regulatory and methodological base of Ukraine for means of measuring equipment.

In the manufacture (repair) of products of transport pipeline systems, auxiliary materials are widely used, which play the role of lubricants, cooling, cleaning and other substances. Special requirements are imposed on the composition of such substances, which are developed in accordance with the technological instructions, since they are, as a rule, chemically active, surfactants of organic and inorganic origin. Therefore, not only the quality of processing of structural elements of transport pipeline systems, but also the environmental safety of the techno-logical process of their manufacture (repair) depends on the composition and mass fraction of ingredients in these substances. Of particular importance in solving problems on this problem belongs to the theory of predicting the formation of the composition of effective auxiliary materials, assessed by technological, economic, sanitary and hygienic and other indicators that are directly related to the formulation of these materials. The theoretical foundations and methods for creating auxiliary materials for technological purposes in the practice of specialized enterprises are implemented using the example of a simplified technological scheme. Ac-cording to this scheme, the action of each source of deviations (errors in the composition of the auxiliary material) is evaluated separately, and the other sources are “off,” that is, the principle of superposition is implemented. For a qualitative reflection of the technological uniformity of any two constituent ingredients in terms of their influ-ence coefficients, the concept of "intersection" is used, and all possible intersections between pairs of constituents form a square matrix of intersections of dimensions. The level of effective homogeneity, which predetermines the quality of the auxiliary material for technological purposes, depends on two groups of indicators that equally affect this effective homogeneity. Thus, any variant of the formulation of an auxiliary material consisting of groups of constituents with the maximum level of objective closure always corresponds to a certain variant of an ordered series of ingredients.
