Abstract

When switching to technological regulation in the Russian Federation, enterprises were divided into categories of negative impact on environmental objects. The most significant impact is exerted by enterprises of the 1st category of negative impact on the environment. Under the new requirements, such enterprises must receive a comprehensive environmental permit (CEP), in which one of the components is compliance with technological standards. If actual values do not match, enterprises should implement a program to improve environmental performance. The work examined technological solutions for use, which environmental impact will meet the requirements of the best available technologies (BAT). Measures are proposed to achieve the levels of technological standards for the existing pulp and paper industry (PPI), using the method of sulfate pulping. The values of indicators of identification of water management activities used in modern legislation are determined: anthropogenic load index (ALI), impact potential (IP), technological impact index (TII), coefficients of water resources involvement in the technological process before and after events.
