EIA of Pipeline Terminal for storage and Marketing of Petroleum Products and Marketing of Petroleum Products At Tikri Kalan, Delhi Including Pipeline from Mathura-Jalandhar Pipeline (MJPL) CHAPTER-4 ANTICIPATED ENVIRONMENTAL IMPACT & MITIGATION MEASURES 4.0 Introduction The previous chapters describe probable impacts identification on each component of the environment and the compilation of the existing baseline data of those components. The quantification of likely impacts and their evaluation/assessment are discussed in succeeding paragraphs. Prediction of impacts is the most important component of an EIA study. Many scientific techniques and methodologies are available to predict impacts on physico-ecological and socio-economic environment. The prediction of the impacts helps to identify the gaps and implement Environmental Management Plan during and after the execution of the developmental activity to minimize the deterioration of environmental quality. In the present study, the most probable impact on various components of the surrounding environment viz. air, noise, water, land, biological and socio-economic, due to the proposed development has been predicted. 4.1 Air Environment The proposed pipeline project would not result in increase in air pollution. In view of this no additional air pollution control measure is needed .On the other hand, if required other pollution control measure will be adapted. 4.2 Noise Environment Sources of noise during operational phases and their predicted impacts are discussed below: 4.2.1 Noise Generation During Operation During operational phase of the pipeline the noise is generated due to various equipments, besides road ,traffic will also contributes to the noise levels in the area. However during construction phase noise will be generated due to momentum of heavy vehicle but it will be temporary in nature. 54 MANTEC CONSULTANTS (P) LTD., NEW DELHI EIA of Pipeline Terminal for storage and Marketing of Petroleum Products and Marketing of Petroleum Products At Tikri Kalan, Delhi Including Pipeline from Mathura-Jalandhar Pipeline (MJPL) 4.2.2 Propagative Modeling The sound power radiated by a source spreads in the space as the pressure waves travel outwards. Hence, it decreases with distance and also gets affected by environmental conditions. Prediction of anticipated noise levels is the most critical step in assessment of the impacts of any development on the noise environment. Two simple models for noise level predictions are point source and line source model. Point source Model Point source propagation can be defined as: P2 = P1 – 20 log (r2/r1) – Ae Where, P1 = Sound level at station 1 P2 = Sound level at station 2 r1 = Distance of station 1 from source r2 = Distance of station 2 from source Ae = Attenuation by environmental factors If we take Ae = 0, then P1 – P2 = 20 log (r2/r1) This means that for every doubling of distance, the sound level decreases by 6 dB(A). This point source relationship is called the inverse square law and applicable for single noise generating source. Line source Model Line source propagation occurs when there is a continuous stream of noise sources. Line source propagation prediction is as follows: P1 – P2 = 10 log (r2/r1) The decrease in sound level for each doubling of distance from a line source is 3 dB(A). When noise levels from a busy highway are considered, it is appropriate to utilize the highway as an infinite line source and consider a 3 dB(A) doubling distance propagation rate. 4.2.3 Impacts Due to Project Simulation carried out for the proposed project with the help of above model indicates that the impact of noise levels would be restricted within the plant limits and is of concern for work place environment rather than 55 MANTEC CONSULTANTS (P) LTD., NEW DELHI EIA of Pipeline Terminal for storage and Marketing of Petroleum Products and Marketing of Petroleum Products At Tikri Kalan, Delhi Including Pipeline from Mathura-Jalandhar Pipeline (MJPL) the outside plant area. The monitored noise level in the vicinity of the plant boundary shall be maximum, 72 dB(A), and minimum during day time, and 40 dB(A), and maximum, 65 dB(A), and minimum, 36 dB(A) during night time against National Ambient Noise Standards of 75 dB(A) for day and 70 dB(A) for night for the industrial zone. The noise level in the nearby residential localities was less than the industrial areas, as monitored during study. However, due to increased vehicular movement for loading and unloading during the operational phase of the proposed project, there might be some increase in the background noise levels. It may be further noted that these predicated noise levels did not account for any constructional hindrances in the way of these noise generating sources. 4.3 Water Environment Industrial wastewaters, if discharged into surface or ground waters can result in significant deterioration in its quality. The extent of such influences, in addition to wastewater characteristics and quantity, also depends upon characteristics and quantity of available water in the water body used for the disposal. 4.4 Land Environment 4.4.1 Impact on Soil As discussed earlier there is no discharge of treated liquid effluent generated from the proposed plant. Also effluent after treatment does not contain any harmful pollutants to deteriorate soil characteristics on percolation. 4.5 Biological Environment The existence of certain type of flora and fauna is the result of a long drawn natural process involving complex interaction between the prevailing meteorological conditions (cumulative effect of various climatic parameters) and the location specific geo-topo features of the land mass in a particular region. The nature has an inbuilt and interwoven network of processes of major concern which are, otherwise, directly or indirectly interlinked with each other. Thus, any man-made alternation or deviation from the set natural course would obviously exert certain effects, which may be either positive or negative on the existing flora and fauna. 56 MANTEC CONSULTANTS (P) LTD., NEW DELHI EIA of Pipeline Terminal for storage and Marketing of Petroleum Products and Marketing of Petroleum Products At Tikri Kalan, Delhi Including Pipeline from Mathura-Jalandhar Pipeline (MJPL) Hence, the scope and relationship of the plants and animals with the surrounding environment has to be examined in the context of the man made project specific development, be it an industrial venture, irrigation works, transport communication network, urbanization project etc. Further, to circumvent the adverse effect, if any, it also becomes mandatory to make some conscientious approach or to foster a systematic understanding and the relationship between man made efforts and the environmental resources. As given below, the impacts have been categorized into two broad types, namely, 1. 2. Those connected to construction phase and That likely to accrue after the project becomes operational. 4.5.1 Impact on Natural Resource Soil or Agricultural Land In the post operational stage, no impact on the soils at site is envisaged as no acquisition of land was required due to its location in MCD area. 4.5.2 Impact on Terrestrial Ecology (Flora and Fauna) A common apprehension of setting-up a project or an industrial complex at any place is the adverse impact on the wild life and the ecologically sensitive areas. Pertaining to the aforesaid project, extensive observations made so far have not revealed the existence of any endangered flora and fauna in the immediate surrounding of the project site and in a study area of 15 km radius. Hence, the possibility of adverse impact on the prevailing ecological environment was negligible. 4.5.3 Impact on Forest & Wild Life There would not be any impact on the Forest and Wild life, as no forest area and wild life was present in the study area. 4.5.4 Impact on Aquatic Ecology The study area as such did s not have any significant water body. 57 MANTEC CONSULTANTS (P) LTD., NEW DELHI EIA of Pipeline Terminal for storage and Marketing of Petroleum Products and Marketing of Petroleum Products At Tikri Kalan, Delhi Including Pipeline from Mathura-Jalandhar Pipeline (MJPL) 4.6 Socio-Economic Environment 4.6.1 Introduction Many major impacts associated with certain proposed actions are observed by changes in socio-economic factors in the project area and surrounding region. These changes may be beneficial or detrimental. Emphasis in this category of environment includes cultural, economic and basic human requirements like education, employment, health, water, power, transport and communication. 4.6.2 Impact on Cultural Resources One of the major concerns associated with such an activity is related to the potential impact on cultural resources, which include architectural, historical and archaeological sites, as well as areas of unique importance due to their ecological, scientific, or geological importance. The sphere of cultural resources includes not only the precise limits of the project area, but also all surrounding lands (15 km radius from plant) on which the project may have a reasonably direct impact by modifying land use pattern or by opening areas for agriculture or for public use. Cultural resources are becoming more and more important with the growing realization that our environment and civilization are the products of history. Cultural resources are non renewable and this feature in itself is one reason that these resources are important. Impacts on cultural resources broadly include indentation, destruction, damage and disruption. Impacts can directly result from construction phase disturbances or indirectly as a result of land use changes, secondary growth and development. The study area primarily consists of agricultural land, apart from local village areas. Local resources of importance to ethnic groups, such as burial grounds and cemeteries or areas of unique religion importance such as temples, mosques etc. do not have any adverse impact, direct or indirect from the proposed pipeline project. 4.6.3 Impact on Economic Features The overall economic impact due to the project is favourable as new areas adjoining the plant for providing utilities and services to the workers and staff members have also developed. This has increased the overall income due to indirect business generated and also exchequers due to the project establishment. 58 MANTEC CONSULTANTS (P) LTD., NEW DELHI EIA of Pipeline Terminal for storage and Marketing of Petroleum Products and Marketing of Petroleum Products At Tikri Kalan, Delhi Including Pipeline from Mathura-Jalandhar Pipeline (MJPL) Summary of the mitigation measures during construction of loop line and modification in pumping stations are tabulated as Table-4.1.
