North Eastern Coalfields Tender

A. For Group – I Name of Work: Generation of one season environmental baseline data for Air, Water, Noise and Soil analysis

Ambient Air Sampling and Analysis is to be carried out as per G.S.R. 742(E) dt. 25th September, 2000 Ambient Air Quality Standard for coal mines and as per G.S.R. 826 (E) dated 16.11.09 of MoEF/National Ambient Air Quality Standards (NAAQS), CPCB notification vide No.B-29016/20/90/PCI-L dated 18th Nov 2009 and subsequent amendments (if any)and preparation of a consolidated one season report. {The consolidated report should cover all the stations of the project. The report should also include the micrometeorological study for the season as described in NIT. There will be one station for each project to generate micro-meteorological data .) Note: The frequency of air sampling at each station would be twice a week i.e for SPM, RPM (PM10), PM2.5, SO2, NOx, for twenty-four hours duration for twelve weeks in one season i.e 2 sample per week x 12 weeks= 24 samples per station in a season and once in a month for Ammonia, Carbonmonoxide, Ozone, Benzo(a) pyrene, benzene and trace metals on air filter paper i.e As, Cr, Ni, Cd, Hg, Pb}. Quoted rates per station should be inclusive of the apportioned cost towards generation of micro-meteorological data for the season and preparation of consolidated report, all inclusive as per the direction of Engineer-in-Charge. Parameters Silica Shall also be analysed in ambient air quality once in a month. No of Stations: 12 No of Samples=Parameters to be monitored twice a week:2 days x12=24 samples per station in a season,Total Samples(in 3 Months)=288
