Environmental Impact Assesment

A study was carried out on a complaint in a municipality for possible air pollution, odour, and industrial effluents. A cross-sectional study resulted with noise levels assessed in the factory (n=12; 8 in-situ and 4 ex-situ). 66.67% locations (n=6) did not comply. Ventilation, lighting and humidity were measured (n=9) where relative humidity recorded was highest at the Banbury mixer (70.7%) and highest temperature recorded was at the oven area (39.9 0C). Air pollution parameters recorded didn't exceed the PEL except for NO₂ and as the highest risk it was >1. The public survey n=32) in Taman Gembira and Taman Aman residential area showed 3 sources of odour problems i.e. drains, factory effluent, and solid waste. Risk assessment identified hazards showed air pollution for NO 2 as the highest risk (risk score=16 as extremely high with the likelihood and consequences to be either major or critical) (DOSH, 2008). The noise levels at the Banbury and Dump mill machine exceeds standard for dose exposure at 93.5 dB (A), while the lowest reading of dose exposure of noise is 74.7 dB (A). Boundary noise to west is 40 dB (A) [standard = 60 dB (A)], the readings in east (85), north (75) and south (70) are above the limit. The factory does not have sufficient buffer zone (<500 meter from residential areas). Noise considered as a major health problem (5 readings > permissible levels). NO 2 exceeds the standards and IARC (1987), classified rubber industries as Group 1: Carcinogenic to humans. Odor is a major issue. There is no bund to contain any spillage of schedule wastes. Recommended for noise controls with engineering controls and administrative controls. Local authority may take action on persons who commit nuisances or it be closed, shifted, changed or modify the machinery used or change production time to comply with the laws. Industrial hygiene (good housekeeping) and maintenance needs to be improved.

In mining operations carried out below the water table, mine area could potentially affect the surrounding. With further deepening of the mine and quarry, the drawdown can impact on water supply wells and base flow. The variation in radius of influence under confined and unconfined aquifer condition is assessed using a hypothetical case study with three operational quarry sites. Average pit-wise radius of influence (R0) for the pit mine, under unconfined and confined aquifer conditions is 963 m and 61 km, respectively, whereas effective radius (Re) for total (cumulative) excavated mine area is 1.7 and 146 km, respectively. It means that the maximum and minimum value of overall impact/influence for the unconfined aquifer lies in-between 963 m and 1.7 km. Similarly that the maximum and minimum value of overall impact/influence for the confined aquifer lies in-between 61 and 146 km. Meanwhile, Re or effective radius for total (cumulative) excavated area seems more appropriate from evaluation viewpoint due to the overlapping (superposition) concentric mining quarries. Thus, assessment of quarry-wise and total radius of influence is of importance to fulfil targeted production, economically with minimum interruptions as part of the mine planning. Moreover, it helps us to assess, monitor and regulate the impact of a mine-dewatering program in the area. Also, the pumping test is often used to estimate radius of influence; it can trigger the inflow or radius of influence. Estimate of the radius of influence using analytical equation mainly independent of discharge/abstraction from the aquifer stands as a preferred choice for the prediction of radius of influence at the quarry/mine pit. There is a strong rationale that policies should be informed by such analytical assessment because it helps us to prevent or minimize negative impacts as part of regulation and pit-mining management and are useful tools for practitioners to design economically efficient and cost-effective in situ groundwater remediation systems, to contain contaminant plumes, to evaluate the surface–subsurface water interaction and to verify numerical models.

The present study was undertaken to assess the quality of water by using physico
chemical parameters of Wyra reservoir of Khammam district, Telangana, India.
Monthly changes in physico-chemical parameters were analyzed for a period of
one year from 2011 January to December. In the present study air, water
temperatures, Dissolved oxygen, alkalinity, chlorides, Total dissolved solids and
hardness turbidity etc, Results indicated that the quality of water from this reservoir
is within the acceptable values. On the basis of the limnological analysis, it was
found that, some physico- chemical parameters showed seasonal fluctuations. It has
been found that the water can be used for drinking purpose in winter and summer
seasons, and also water can be used for irrigation and pisciculture.

ABSTRACT: Sied National Park is one of seven National Parks established in Saudi Arabia. The study evalu-ates the species diversity of the vegetation inside the park compared to the vegetation outside the park. The vegetation data set was based on the importance value of species from 18 stands representing the sections of the park and 8 stands representing the habitat around the park. TWINSPAN, diversity indices, and ANOVA were used to analyze the obtained data. Twenty one families were recorded in Sied Park, while 17 families were recorded outside the park. The families inside the park comprise 49 species including 32 perennials and 17 annuals, while 27 species are recorded outside the park including 20 perennials and 7 annuals. The vegetation inside the park is divided into five plant groups dominated by Heliotropium crispum, Fagonia bruguieri, Penisitum divisum, Lasiurus scindicus, Cynodon dactylon, and Cymbopogon commutatus, while outside the park, the vegetation was divided into three plant groups dominated by Rhanterium epaposum and Rhizyaa stricta. These results are discussed in relation to the edaphic variables, the type and the absolute density of the cultivated trees in the park.

There is paucity of data on the awareness of Environmental Impact Assessment across communities where environmental assessments have been completed for different ranges of projects. This has raised concerns for stakeholders and policy makers for decision making as part of improving the sustainability initiatives in the built environment. The research examined the perception of the public in Anambra State after post environmental impact assessment tasks in communities have been completed. This was to ascertain the extent of public awareness on the implications of EIA in the built environment. The field survey employed techniques such as survey method, focused group discussion, interview and observation to elicit information from the 450 respondents of the three communities: Uruezi Egbema Village Ozubulu, Aboh Amawa Ogbunike and Umuofor Ubahu Village, Okija, where selected Environmental Impact Assessment projects are located. Purposive sampling technique was employed. The hypothesis that guided the study was: Reaction and perception of residents to EIA as an instrument of environmental sustainability and governance do not vary across communities studied. The results supported the hypothesis as the calculated X 2 was greater than the critical values at both 0.05 and 0.01 alpha levels. Awareness level and mitigation measures were shown to be poor. This raised serious concern on the implications of the level of awareness in environmental management issues in the study localities. It is therefore recommended that efforts must be made to improve EIA awareness through capacity building and enforcement of mitigation measures with available grants and incentives in environmental management. It is hoped that the findings will be useful to EIA practitioners and to ministries of Environment across the states of the Federation in Nigeria and thus provide a general guideline for other researchers in EIA quality evaluations.

Diversos autores han observado un tránsito de menor a mayor complejidad en las políticas de evaluación ambiental, pasando desde un enfoque originariamente sectorial hacia una perspectiva sistémica y estratégica. Sin embargo, como en todo proceso político, estos tránsitos no son homogéneos ni lineales. De hecho, existen importantes diferencias en los sistemas de evaluación ambiental del Norte y del Sur global. En este ensayo conceptual y bibliográfico, analizamos cómo las premisas del crecimiento económico tensionan el diseño y la aplicación de normativas para la evaluación ambiental en América Latina y Chile, dificultando la construcción de una evaluación sistémica, estratégica y democrática con la urgencia que se requiere en el contexto crítico del Antropoceno.

There has been much public debate recently regarding expansion of the golf course at Lipica in response to the environmental impact report and assessment of the acceptability of the effects of carrying out the plan. Although the assessment followed the prescribed procedure, in which the experts involved conducted their work with scientific independence at all times, discussions often descended to the level of populist rhetoric. Both the general public and the professional community objected to the environmental impact report's final assessment, which was »C – negligible impact, conditional (on carrying out mitigation measures).« An especially large number of critics concerned the landscape segment. This article sets forth some issues that arose during the process of assessing the landscape segment and presents them in the light of current approaches to dealing with and studying the landscape.

Compliance with Section 106 of the U.S. National Historic Preservation Act is often and understandably seen as an unduly complicated, expensive, and unproductive part of environmental impact assessment. Past efforts to "streamline" review have often made it more complicated and less effective. We propose a simple amendment to the statute, eliminating reliance on the National Register of Historic Places and clarifying the purposes of review.

Concepts of justice are implicit to impact assessment (IA) procedures and policies. A closer examination of the academic literature on environmental justice reveals plural meanings and practices. We present data from a scoping review of the academic literature on IA guided by a trivalent definition of environmental justice encompassing distribution of environmental harms, recognition of diverse ways of knowing, and representation of plural perspectives through democratic procedures. We use this trivalent framework to assess how justice is defined in English language IA journal articles from 2000 to 2019. Findings show an emphasis on distributive and procedural dimensions of justice, with significantly less attention given to issues of recognition and framing. Broad definitions of environmental justice can assist IA scholars in attending to justice-seeking claims across various IA practices and settings, including implications for how IA addresses the concerns of marginalized groups.
