Air Environment. Contractor shall fully cover any and all loads of loose construction materials including without limitation, sand, dirt, gravel, asphalt, excavated materials, construction debris, etc., to protect said materials from air exposure and to minimize emission of airborne particles to the ambient air environment within the City of Xxxxxx Island.
Air Environment. The ambient air quality monitoring was carried out at 8 locations. The parameters monitored during the study period were Particulate Matters (PM), Sulphur dioxide (SO2), Oxides of nitrogen (NOx), Carbon Monoxide (CO). The results of AAQM are depicted in the Table 8.
