Sanitary protection zones in the existing development

The sanitary protection zone is a widespread, but still not clearly defined concept in the legislation. According to the RF Government Decree No. 222 the SPZ design project is required to justify the size of the sanitary protection zone of the object, and its border must be put on cadastral records for all industrial facilities. Accordingly, the SPZ design issue is relevant for all industrial facilities without exception. This work is based on the SPZ project data of a real enterprise for the production of car components from polyurethane foam in Kaluga. Justification of the SPZ size is carried out on the basis of the received cartographic and tabular materials. The calculation of the dispersion of harmful substances in the atmosphere, assessment of noise impact, impact on the landscape and assessment of the SPZ by a combination of factors are performed. The criterion for determining the SPZ size is not exceeding at its border hygienic standards, established for the atmospheric air of populated areas as 1 MPC. According to the factors of acoustic and chemical impact, it is proposed to establish the variable boundary of the SPZ from the boundary of the industrial site. Calculations for other types of negative impact are not carried out, their impact is assessed as insignificant. The integral size of the object SPZ is established on the basis of the calculations by a combination of factors. A program for instrumental control at the border of the design SPZ with the selected design control points is being compiled. If the fact of exceeding the MPC is revealed, additional measures are provided to achieve full compliance with the established standards. The main unfavorable factors of the production activity impact on the environment and humans are emissions of pollutants into the atmosphere and sources of acoustic exposure. Currently, an urgent problem is the development and implementation of environmental standards for the quality of atmospheric air for its chemical properties. In certain situation it would be advisable and even necessary to additionally estimate the total value of pollutant emissions per year.
