Appendix 1: Air Quality Impact Assessment
2 ENVIRONMENTAL TOPICS
2.1 AIR QUALITY
2.1.1 Summary of Baseline Findings and Sensitive Receptors The geographical location of the Project area in the foothill of Ile Alatau (Trans-Ili Alatau) influences the climatic characteristics due to the existence of altitudinal zonation and mountain-and-valley air circulation. According to the Köppen-Geiger climate classification, the climate within the Project area is defined as 'hot-summer humid continental climate'. The Project area lies in two boreal climate zones, Dfa and Dfb1. The climate of the Project area is characterized by moderately cold winters, fast and humid mid-seasons, hot and dry long summers and relatively increased amount of average annual precipitation (compared to the surrounding area). Mountain winds (with southern component), which bring cold air, are recorded shortly after sunset and continue until sunrise. During the day, the winds from the foothills towards the mountains (the Northern component) prevail. According to the map of climatic zoning of SNiP 2.04-01-2001 (SNiP RK 2.04- 01-2001 construction climatology) the subject area is situated in Climate Area III (Sub-area IIIB) 2. Air quality observations in the area of Almaty city are being conducted by national hydrometeorology service (Kazhydromet) on 11 monitoring stations, in 5 manual sampling points and in 4 points by mobile laboratories. All of them are located in the centre of the city and far from the BAKAD RoW. Air quality monitoring is carried out for the following parameters: particulate matter, sulphur dioxide, carbon monoxide, nitrogen dioxide, phenol and
formaldehyde. The exceedances of the average daily MPC (MPCDA) and
maximum permissible/allowable non-recurrent concentration (MPCMNR) were recorded during the measurements
1 Dfa = Hot-summer humid continental climate; coldest month averaging below −0 °C (32 °F) (or −3 °C (27 °F)), at least one month's average temperature above 22 °C (71.6 °F), and at least four months averaging above 10 °C (50 °F). No significant precipitation difference between seasons (neither abovementioned set of conditions fulfilled). Dfb = Warm-summer humid continental climate; coldest month averaging below −0 °C (32 °F) (or −3 °C (27 °F)), all months with average temperatures below 22 °C (71.6 °F), and at least four months averaging above 10 °C (50 °F). No significant precipitation difference between seasons (neither abovementioned set of conditions fulfilled).
2 The moderate climate region. The average monthly air temperature in January varies from -5°С to -14°С; the average monthly air temperature in July varies from +21°С to +25°С
ERM EURASIA BAKAD ESIA BAKAD CONSORTIUM ESIA REPORT: TECHNICAL APPENDIXES, VOL. III Addition to Vol. II-REV 3 1 In accordance with the information bulletin on the environmental conditions of the Republic of Kazakhstan (2017) (The RGP "Kazhydromet". Department of environmental monitoring) the level of air pollution in the area of Almaty is characterized as increased (API1 - 6 units).
