11.3 EXTENT OF STUDY AND AREA COVERED

The baseline status of environmental quality in the vicinity of project site serves as the basis

for identification, prediction and evaluation of impacts. The baseline environmental quality

is assessed through field studies within the impact zone for various components of the

environment, viz. air, noise, water, land and socio-economic. The baseline environmental

quality has been assessed in the winter season (December 2010 – February 2011) in a study

area of 10 km radial distance from the project site.

11.4 METHOD OF STUDY

The study is based on guidelines of MoEF and identifies the nature of activities involved

and their impacts caused on various environmental parameters. It subsequently suggests

mitigation measures to be executed for safeguarding against any environmental degradation.

Finally, it suggests methods of implementing the environmental management plan.

The ambient air quality monitoring was carried out in accordance with guidelines of Central

Pollution Control Board (CPCB) of June 1998 and National Ambient Air Quality Standards

(NAAQS) of CPCB of November 2009. Ambient Air Quality Monitoring (AAQM) was

carried out at five locations during winter season. The maximum numbers of sampling

locations were selected close to the project site and in the study area of 10 km radial

distance around the plant site. The monitoring was carried out 24 hours a day twice a week

per location in the study area except the project site, where continuous monitoring was

carried out. Twenty four numbers of observations were taken at each monitoring location

except the project site.

The conventional and project specific parameters such as PM10, PM2.5, SO2, Nox, HF were

monitored at site.


2011


[11-10]

The values for mentioned concentrations of various pollutants at all the monitoring locations

were processed for different statistical parameters like arithmetic mean, minimum

concentration, and maximum concentration and percentile values.

11.13 WATER RESOURCES

Water will be used from Existing Bore wells in the premises. No New bore wells are to be

dug. Rain water recharging scheme will be incorporated hence the impact on ground water

will be minimized.

11.13.1 Ground Water Quality

The unit is a Zero Discharge unit and Sewage will be allowed in Septic Tank.

M/s. T. J. Agro Fertilizers Pvt. Ltd. will take all precautions to make its solid waste areas

impervious to water and leachate migration.

Hence it follows that ground water quality is not adversely impacted by M/s. T. J. Agro

Fertilizers Pvt. Ltd. activities.

11.14 NOISE LEVELS

Noise levels envisaged shall be within prescribed limits of GPCB at plant boundary, after

implementation of the mitigation measures. DG Sets will be Acoustically Enclosed type.

Green belt development will be made. Hence there will be no adverse impacts on existing

noise levels due to the proposed production activities.

11.15 SOIL / LAND QUALITY

M/s. T. J. Agro Fertilizers Pvt. Ltd. will take all precautions to make its Raw Material

Storage, Product Storage, hazardous waste storage area impervious to water and leachate

migration. This will prevent soil contamination.

It follows that soil quality will not be adversely impacted by proposed production activity.

11.16 ENVIRONMENTAL MANAGEMENT PLAN

An environment management plan has been proposed in this report to implement the mitigation

measures. The plan will ensure that the adverse environmental impacts are minimized and the

beneficial impacts are maximized. Detailed plan is discussed in Chapter No. 8 of EIA report.

Total plot area of the project is 10,000 m2. Total Proposed Greenbelt area will be 1255 m

2. This

development has been already started. This will attune noise levels and dust levels by acting as a

barrier between the outside environment and the inside environment of the premises.

11.19 MONITORING SCHEDULE

A monitoring schedule has been prepared to ensure effectiveness of the environmental

management plan.

11.20 EXPENDITURE FOR ENVIRONMENTAL ACTIVITIES

M/s. T. J. Agro Fertilizers Pvt. Ltd. will spend Approximately Rs. 21.75 Lacs as capital

expenditure on environmental management. The recurring cost is Approximately Rs. 3.5 Lacs per

annum.

11.21 CONCLUSION

The following can be concluded based on the study:

Due to the plant operation no adverse impacts envisaged on Ambient Air, Noise, Ground

water, Land & Soil.

Risk to soil is negligible due to effective management and handling of hazardous wastes and

wastewater.

Socio-economic benefits due to generation of direct / indirect employment.

Thus, it can be concluded on a positive note that after the implementation of the mitigation

measures and Environmental Management Plan the activities of M/s. T. J. Agro Fertilizers Pvt.

Ltd. will have negligible impact on environment and will beneficial to the nearby residents.
