Grounds for Scientific/methodic Approaches to Determination of Norms of Permissible Impacts to Offshore Sea Water Areas

Overview and analysis of contemporary scientific/methodic approaches to determination of norms of permissible adverse impacts in terms of chemical and suspended matter input to offshore sea water areas are presented. The pollutants concentration balance model correlated to the volume of sea water area under investigation with consideration of limiting conditions that provide maintaining of the marine environment normal state has been considered. Balance elements of the pollutants supplied to offshore sea water areas with industrial and domestic waste waters and with diffuse discharge, as well as pollutants input with water exchange of the calculated site with the neighboring sea range have been determined. An ecological approach to the problem of permissible impact norms based on the notions of maximal permissible ecological load, maximal permissible adverse impacts and the sea assimilation capacity has been analyzed. Grounds for the methodology of the norms determination in terms of chemical and suspended matter for certain parts of offshore sea water areas and bays with different water exchange characteristics have been provided.
