DISPERSION MODEL FOR COMPUTATION OF GROUND LEVEL CONCENTRATION

OF POLLUTANTS

INTRODUCTION The Environmental Impact Assessment (EIA) notification of September 14, 2006 the Ministry of Environment & Forests (MOEF), Government of India, requires that project proponents obtain clearance from MOEF before siting a new industry or for expansion of an existing industry through an EIA study, which interlay necessitate evidence of attainment of satisfactory ambient air quality in the vicinity of their source complex through dispersion modeling.

Dispersion Models are mathematical expression relating emission of pollutants to its concentration at a given location. Planning of sustainable development involves some assessment or prediction and dispersion models help in predicting the impact of a proposed activity on environment. Models simulate the relationships between air pollutant emissions and the resulting impact on air quality. The inputs to the model include emissions, meteorology and air chemistry, all of which are determined by formulating impact scenarios. When pollutants are emitted into the atmosphere, they are immediately diluted, transported and mixed with the surrounding air. The role of air quality modeling is to represent these processes mathematically. The present practice for ambient air quality predictions is through application of Gaussian Plume Model and its available variations. The experience so far, has shown that the values of parameters are often adopted from other countries without understanding their applicability in Indian context. It has also been observed that various forms of Gaussian Plume Model are used without providing any reasonable justification in doing so. In view of the above shortcomings, it was felt that there is an immediate need to evolve certain guidelines for conducting air quality modeling. To formulate these guidelines, the Central Pollution Control Board constituted an expert committee to bring out a uniform and acceptable modeling procedure. The merits in formulating these guidelines include indiscriminate application of Gaussian Plume Model to proponents' advantage/disadvantage and to provide a uniform and acceptable procedure for conducting air quality modeling. The above-referred guidelines for air quality modeling have been followed to determine Ground Level Concentration of pollutants.

A-21

BASIC PRINCIPLES After discharge, the air emissions from stationary point sources are subjected to transport and diffusion process (dispersion). The following process governs the atmospheric dispersion of pollutants:

An initial vertical rise called the plume rise (due to buoyancy and momentum of discharge).

Dispersion by turbulence in wind in horizontal and vertical direction Adequate transport by wind in its direction A fourth factor affecting the emission concentration in the atmosphere is depletion, which is due to: Gravitational Settling - significant for particles of size greater than about 10 µm; Chemical reactions and decomposition; Deposition on vegetation and other surfaces; Wash out due to rain; A combination of complex physical and chemical processes, i.e. coagulation of

particles, desorption of deposited vapors, etc. ISC SHORT - ERM DISPERSION MODEL The Industrial Source Complex (ISC) Short Term model provides options to model emissions from a wide range of sources that might be present at a typical industrial source complex. The basis of the model is the straight-line, steady-state Gaussian plume equation, which is used with some modifications to model simple point source emissions from stacks, emissions from stacks that experience the effects of aerodynamic downwash due to nearby buildings, isolated vents, multiple vents, storage piles, conveyor belts, and the like. Emission sources are categorized into four basic types of sources, i.e., point sources, volume sources, area sources, and open pit sources. The ISC Short Term model accepts hourly meteorological data records to define the conditions for plume rise, transport, diffusion, and deposition. The model estimates the concentration or deposition value for each source and receptor combination for each hour of input meteorology, and calculates user-selected short-term averages. For deposition values, either the dry deposition flux, the wet deposition flux, or the total deposition flux may be estimated. The total deposition flux is simply the sum of the dry and wet deposition fluxes at a particular receptor location.

A-22

GAUSSIAN PLUME MODEL The ISC Short Term model uses a steady-state Gaussian plume equation to model emissions from point sources, such as stacks and isolated vents for a continuous elevated source. For each source and each hour, the origin of the source’s coordinate system is placed at the ground surface at the base of the stack. The x-axis is positive in the downwind direction, the y-axis is crosswind (normal) to the x-axis and the z-axis extends vertically. The fixed receptor locations are converted to each source’s coordinate system for each hourly concentration calculation. The hourly concentrations calculated for each source at each receptor are summed to obtain the total concentration produced at each receptor by the combined source emissions.

For a steady-state Gaussian plume, the hourly concentration at downwind distance x (meters) and crosswind distance y (meters) is given by:

QKVD

X (x,y,z) = ------------------ exp [-0.5 (y/2σy)2 ] ……….. Equation 1.1

2 p u Sy Sz

where:

X = Concentration of pollutant at a point (x, y); (g/m3) Q = Source strength (Pollutant Release Rate); (g/s) u = Horizontal wind speed at the source level; (m/s) Sy & Sz = Vertical & Horizontal crosswind dispersion coefficients respectively,

which are a function of downwind distance 'x' and atmospheric stability; (m)

K = A scaling coefficient to convert calculated concentrations to desired units (default value of 106 for Q in g/sec and concentration in g/m3)

V = Vertical Term, which includes the effects of source elevation, receptor elevation, plume rise, limited mixing in the vertical, and the gravitational settling and dry deposition of particulates (with diameter greater than 0.1 microns)

D = Decay Term

The ISC model uses either a Polar or a Cartesian receptor network. The model allows for the use of both types of receptors and for multiple networks in a single run. All receptor points are converted to Cartesian (X, Y) coordinates prior to performing the dispersion calculations. In the Cartesian coordinate system, the X-axis is positive to the east of the user-specified origin and the Y-axis is positive to the north. Cartesian coordinates will be used to locate receptor network in ISC model. The ISC model is designed to have 500 receptors, 100 sources, 2 source groups and 2 numbers of short-term averages.

OVERVIEW OF MODELLING OPTIONS DISPERSION OPTIONS: The ISC models are especially designed to support the EPA’s regulatory modeling programs, the regulatory modeling options, are the default mode of operation for the models. These options include the use of stack-tip down wash, buoyancy-inducted dispersion, final plume rise (except for source with building downwash), a routine for processing average when calm winds occur, default values for wind profile exponents and for the vertical potential temperature gradients, and the use of upper bound estimates for super-squat buildings having an influence on the lateral dispersion of plume. The short-term model also incorporates the COMPLEX 1 screening model dispersion algorithms for receptors in complex terrain, i.e. where the receptor elevation is above the release height of the source. The user has the option of specifying only simple terrain (i.e. ISCST) calculations, only complex terrain (i.e. COMPLEX 1) calculations, or of using both simple and complex terrain algorithms. The user may select either rural or urban dispersion parameter, depending on the characteristics of the source location. The user also has the option of particular run. For the short term model, the user may select more than one output type (concentration and/or deposition) in a single run, depending on the setting for one of the array storage limits. The user can specify several run of the ISC short-term model, as well as requesting the overall period (e.g. averages). SOURCE OPTIONS: The model is capable of handling multiple sources, including point, volume, area and open pit source types. Line sources may also be modeled as a string of volume sources or as elongated of aerodynamic down wash due to nearby buildings on point source emissions, and algorithms for modeling the effects of settling and removal (through dry deposition) of particulates. The short-term model also contains an algorithm for modeling the effects of precipitation scavenging for gases or particulates. For the short-term model, the user may specify for the model to out put dry deposition and/or total deposition. Source emissions rates can be treated as constant throughout the modeling period, or may be varied by month, season, hour-of-day, or other optional periods of variation. This variable emission rate factory may be specified for a single source or for group of sources. For the short-term model, the user may also specify a separate file of hourly emission rates for some or all of the sources included in a particular model run.

A-25

RECEPTOR OPTIONS: The ISC models have considerable flexibility in the specification of receptor locations. The user has the capability of specifying multiple receptor networks and polar grid receptor network in the same run. There is also flexibility in specifying the location of the origin for polar receptor, other than the default origin at (0,0) in x,y, coordinates METEROLOGY OPTIONS: The user also has considerable flexibility to utilize formatted ASCII files that contain sequential hourly records of meteorological variables. For these hourly ASCII files, the user may use a default ASCII format, may specify the ASCII read format, or may select free-formatted reads for inputting the meteorological data. The model will process all available meteorological data in the specified input file by default, but the user can easily specify selected days or ranges of days to process.

OUTPUT OPTIONS: The basic types of printed available with the Short-term model are: Summaries of high values (highest, second highest, etc.) by receptor for each

averaging period and source group combination: Summaries of overall maximum values (e.g. the maximum 50) for each averaging

period and source group combination: and Tables of concurrent values summarized by receptor for each averaging and source

group combination for each day of data processed.

Rain Water Harvesting Scheme

For Proposed Expansion project of

M/s. Asutosh Pellets.

Introduction:

Rain is the most important source of all water on the Earth. Water cycle is unique. In an endless cycle, rain rejuvenates all fresh water resources. Rainwater recharges the surface sources and slowly seeps into the ground to reach and replenish the underground aquifers. Water Harvesting is a technique of recharging ground water by collection, storage and percolation of rain/storm water into the ground water table. It is simply diverting rainwater either towards storage tank or to a recharge structure. Today, water scarcity is one of the major problems being faced by people all over the World, India and specifically Gujarat. Increase in consumption of water and industrialization has resulted in the drastic depletion of the ground water table. This depletion could be arrested by water harvesting. This could be carried out by recharging ground water and reusing it appropriately. Rain/storm water can be harvested by different means, such as Tank Harvesting Using Wells/ Step wells for water storage. Constructing Check Dams / Canals across rivers. Using lakes or constructing ponds/Reservoirs for water collection. Roof top/ Paved area harvesting through percolating wells. The harvested rainwater cannot only be used to meet water requirements of the city, it also recharges groundwater aquifers. The decision whether to store or recharge water depends on the rainfall pattern and the potential to do so, in a particular region. The sub-surface geology also plays an important role in making this decision. Gujarat is an example of places where groundwater recharge is usually practiced.

“M/s. Asutosh Pellets” located at Survey No.: block no 515, Village: Vamaj, Vamaj-Adraj Road, Ta.: Kadi, Dist.: Mahesana, Gujarat plans to adopt Water Harvesting technique out of social concern moral responsibility as well as regulatory requirements. Present Status: Area: Total Land Area : 5498 sq.m. Roof Area : 1500 sq.m Road/ Paved Area : 1387 sq.m Green Belt Area : 2611 sq.m In rooftop rainwater harvesting the rain water is collected from roof of the buildings and stored in ground water reservoir for beneficial use in nature. It could also be used for recharging the ground water. Garden/ Open area has not been considered due to fact that, storm water collection system has not been provided for the same and therefore most of the rain water falling onto the garden / open area would probably percolate in the soil there itself. Thus, Rainfall Catchment Area : 2,887 sq.m. (1500+1387) Intensity of Rainfall: Average Annual Rainfall in Region : 803 mm* Monsoon Period : 35.8 days * Rainfall Per Day : 22.44 mm/day * Ref : Climatological Tables of Observatories in India by India Meteorological

Department Average Runoff:

Average Calculation

Through Roof Area of 1500 Sq.m : 33.66 cu.m /day (1500) * (22.44/ 1000) Through Paved and Roads of 1387 sq.m : 31.12 cu.m /day (1387)* (22.44/ 1000)

Total (2,887 sq.m) : 64.78 cu.m /day (33.66 + 31.12) Total Runoff (Runoff Co-efficient Assumed 0.7)

: 45.35 cu.m /day (64.78 * 0.7)

Proposed Water Harvesting Scheme: For recharging ground water by harvesting rain/storm water at “M/s. Asutosh Pellets”, we suggest the use of percolating wells. This is due to the fact that these are easy to construct, relatively economical and require a small foot –print.

Design And Budgetary Cost Estimate: Design: Diameter of each bore in the percolating well structure : 0.10 m

Depth of each bore in the percolating well structure : 100 m

Vertical Assimilation Rate (Assumed) : 10 cu. m. /sq. m. /day

Runoff Co-efficient (Assumed) : 0.7

Now, Required Percolating Capacity of the Well = Total Average Runoff x Runoff Co- efficient = 45.35 cu. m/day

Total Percolating Area Required = Required Percolating Capacity/ Vertical Assimilation Rate = 45.35 sq.m / (10 cu. m. /sq. m. /day) = 4.53 sq. m

Therefore, the total percolating area of the water harvesting structure should be 4.53 sq m.

Percolating surface area of a 0.15 m Φ Bore = Π x D x L

= 3.14 x 0.10 x 100 = 31.4 sq. m

We are going to provide 2 percolation well. Thus, with 1 harvesting structure, total percolating area will be = 62.8 sq. m Budgetary Cost Estimation: No of Harvesting Structures : 2 No. of bore holes in each of the above water harvesting structures : 1 Cost of each water harvesting structure (1.8 Φ at top) : Rs. 75,000 /-

Total l : Rs. 1,50,000/- The stated cost would include the cost of boring the holes, the strainer pipe cost as well as the masonry work required to be carried out. Benefits of the suggested Rainwater Harvesting Structures: Maintenance free Smooth surface so easy to clean Would reduce groundwater TDS and improve water quality Subsoil water levels would rise over a period of time. Solution to undue water logging in the absence of such percolation No use of electricity Conclusion: It is viable to harvest water using percolating wells at “M/s. Asutosh Pellets” Mahesana.
