Excavation to construct the proposed building foundations and basement level is currently being performed and will be ongoing for approximately the next three weeks. During excavation, soil exhibiting petroleum and organic [i.e. hydrogen sulfide] odors may be generated which may be a nuisance to nearby building occupants, residents and passersby. In order to minimize the odors, the soil will be sprayed with a neutralizing and/or deodorizing agent as it is excavated and loaded onto trucks. The levels of petroleum, hydrogen sulfide and dust in the air are being monitored to make sure that levels do not exceed acceptable levels for the general public.
