The imperfection of the regulatory system of pollutants discharge with wastewater and economic mechanisms for protection of water objects has been discussed in our country for many years. The solution may only be a significant change in the basic approaches, the introduction of technological standards for enterprises emissions. The authors of this article have analyzed information-technical reference books on the best available techniques in order to generalize the data about the determined marker substances and technological indicators for pollutant discharges. Certain drawbacks of the considered reference books have been eventually identified.
