1.2 Present Status of Project Implementation

ACC had to commit resources for setting up new Clinkerisation unit at Jamul as it was mandated by Government to shut down old kiln and setup state of Art integrated plant for the betterment of the environment. Therefore, deployment of resources in Ametha project had to be differed. Now the state of art Jamul plant is commissioned and ACC has now decided to go ahead with setting up Ametha integrated plant covering clinker unit and also 2.0 MTPA grinding unit.

Market demand in the eastern sector was more robust than in central sector. Central sector market had not picked up as expected by us at the time of submitting proposal for setting up plant at Ametha proposal.



Market demand in central sector is huge and due to improvement in market situation in UP we are proposing to set up standalone grinding station at Tikaria-II for which Environmental Clearance is already in place. Ametha clinker unit is the source of Clinker for the proposed standalone grinding unit at Ametha and Tikaria-II project as well. At present project design is in advanced stage of completion. ACC has proposed to complete the construction of Ametha integrated project covering both clinker and grinding unit within 29 months from the receipt of amendment in the Environmental clearance for 2.0 MTPA grinding unit with extension of validity of existing Environmental Clearance and other approval. Project implementation schedule is presented in Annexure-II.

1.3 Location of the Project and Environmental Settings

Ametha project is located near Ametha village, Tehsil Vijayaraghavagarh, Katni district, Madhya Pradesh state. The project site is located 30 km away from the district head quarter Katni. The nearest rail station is Jukehi railway located at 9.5-km from plant boundary in WSW direction. The site is 120 km away from Jabalpur city, which is also the nearest airport. The plant site is located on a flat terrain and no topographical changes are anticipated due to the proposed of 2.0 MTPA grinding unit. No-ecological sensitive habitats like national parks, biosphere reserves, wildlife sanctuary, health resorts and defense installation are present within 10 km radius of the Ametha project.

Detailed environmental settings for the proposed grinding unit is given Table-3. Index map, and location map showing proposed project site and surrounding features within 10 km area are presented in Figure-1 and Figure-2 respectively.

2.8 Cement Manufacturing Process

Cement manufacturing process: Cement manufacturing / grinding involves principally of grinding and blending of clinker with a definite proportion of Gypsum along with fly ash to produce finished product PPC. Few additives may be added during the grinding process to improve the performance of cement. The unit broadly comprises of the following sections. 1. Cement Mill section 2. Packing section 3. Dispatch section

A cement grinding plant for grinding 2 MTPA will be provided along with facilities for unloading, storage, handling for raw materials. The project provides for installation of cement silos and Packing plant for packing of cement in bags. Mechanised loading of facilities shall be provided to for loading operation. Electronic packer machines will ensure better weight compliance also.

Process selection: The process selected for the grinding system is the state of the art modern Mill Technology. This technology is suitable for the production of cement using flyash etc.

Plant operation and maintenance. The entire plant will be operated from a central control room (CCR) by operators, who will be assisted by specialists in plant maintenance. The plant will be highly automated and use state-of-the-art



systems to achieve world class economies in terms of fuel and power consumption and manpower productivity. On-line condition monitoring systems such as vibration sensors, bearing temperatures etc. shall be provided to keep track on the health condition of the major equipment and auxiliaries. Continuous particulate matter monitoring system are installed in the stacks and the readings are monitored by the CCR operators. Manufacturing process flow diagram is given below.

3.0 IMPACT ON AIR ENVIRONMENT

Air quality modelling exercise was carried out to determine the pollution loads considering the emissions from the various sources such as clinker unit, CPP, coal crusher and mining activities which were approved in earlier EC and also considering 2.0 MTPA grinding unit which is proposed under EC amendment. Environmental clearance granted for clinkerisation unit for emission limit of 50 mg/Nm3. As per new emission norms for cement industry, ACC have now decided to design all our ESP and bag filter of clinkering unit to the emission Standard of



30 mg/Nm3. Also ACC will comply with the New Emission Standard for cement industry for SO2 & NOx of 1000mg/Nm3 and 600 mg/Nm3 respectively.

3.1 Air Dispersion Modelling Study 3.1.1 Details of Mathematical Modelling

For prediction of maximum Ground Level Concentrations (GLC’s), air dispersion modelling software (AERMOD version 9.4.0) point and area sources options were used. AERMOD is steady state advanced Gaussian plume model that simulates air quality and deposition fields upto 50 km radius. AERMOD is approved by USEPA and is widely used software. It is an advanced version of Industrial Source Complex (ISCST3) model, utilizes similar input and output structure to ISCST3 sharing many of the same features, as well as offering additional features. The model is applicable to rural and urban areas, flat and complex terrain, surface and elevated releases and multiple sources including point, area, flare, line and volume sources.

Dispersion modelling using AERMOD requires hourly meteorological data. Site specific data is used for executing modelling studies. The site specific meteorological data is processed using AERMET processor.

3.1.2 Model set-up

The model set-up details are presented in Table-7. The predictions of point/stacks (clinker unit, CPP, coal crusher, and proposed grinding unit) and area sources (mining activities) incremental concentrations of particulate matter (PM) pollutant due to emission loads of existing and proposed project installations are estimated based on site specific meteorological conditions. The details of emissions expected from various stacks (point sources) in various units and from mines area sources considered for modeling are given in Annexure-III.

3.1.3 Meteorological Data



Hourly meteorological data have been recorded at site for post-monsoon season of 2016. The site specific meteorological data was converted to the mean hourly meteorological data as specified by CPCB and the same has been used in the current AERMOD modelling.

3.1.4 Scenarios Considered for Model Predictions

Model predictions were carried out for the following scenarios (Table-8) for determination of Particulate Matter (PM) ground level concentrations:

Note: ACC will comply with the New Emission Standard for cement industry for SO2 & NOx of 1000mg/nm3 and 600 mg/nm3 respectively

From the above results, it can be observed that incremental and resultant concentrations of PM reveals a significant decrease in the ambient PM10 levels due to implementation of emission limit of 30 mg/Nm3.

It is to be noted that even after inclusion of proposed grinding unit of 2.0 MTPA, the maximum Ground Level concentration (GLC) were found to be 2.7 µg/m3 and the resultant GLC was found to be 37.9 µg/m3, which is well below the CPCB ambient air quality limit of 100 µg/m3 for PM10.

3.5 Conclusions

• No additional land is required for the setting up of 2.0 MTPA grinding unit. • Utilization of clinker in same unit will result in reduction of 1.24 MTPA clinker

transportation. • Additional power requirement of 10 MW will be met from Kymore Captive

Power Plant. • The additional water requirement of 35 m3/day will be met from the existing

sump of operating mine and water reservoir created at worked out pit of Bamangon mine. No waste water will be generated.

• Significant decrease in the ambient PM10 levels due to implementation of emission limit of 30 mg/Nm3.

• Marginal increase in ambient PM10 levels were expected by additional of 2.0 MTPA grinding unit.

It is to be noted that Environmental Clearance (EC) was granted for clinkerisation unit based on emission limit of 50 mg/Nm3. It is evident that with implementation new emission standard of 30 mg/Nm3, there is a reduction in ambient air quality levels. From the modeling results, after inclusion of proposed 2.0 MTPA grinding unit, the predicted particulate matter GLC’s were found to be slightly higher when compared with the earlier pollution loads of considered for issue Environmental Clearance. Hence, there is no significant impact on the AAQ levels due to the proposed 2.0 MTPA grinding unit.
