Components of the environment that must be described include: 1. Finally, a political decision is taken. Mitigation Measures: i Design system to avoid, reduce and minimize adverse impacts. Oxygen is introduced at the correct levels in to the treatment tank bioreactor to encourage and promote bacteria growth. Probable short-term impacts - Effects of the project that extend beyond the end of construction but only for a short period of time. The accumulated sludge at the bottom of the clarifier is recycled back into the septic tank where it is digested further.
Where appropriate, a non-technical summary including a visual presentation of maps, graphs, etc. The units are designed to suit the number of occupants using the water and toilet facilities. Description of Techniques intended to Minimize Adverse Impacts: Describe the techniques that are available to avoid or minimize adverse impacts of the selected alternative proposal. If required, further treatment will be necessary to make the water suitable for drinking. A beginning in this direction was made in our country with the impact assessment of river valley projects in 1978-79 and the scope has subsequently been enhanced to cover other developmental sectors such as industries, thermal power projects, mining schemes etc. As we progress and the resource planning concepts emerge in our decision- making process, the integration of overall regional issues will become part of the impact assessment studies.
Credibility: Assessment is undertaken with professionalism and objectivity. Energy System in use f. Usually, the design engineer will determine if you need one depending on the scope and type of work being proposed. Environmental Impact Assessment Methods Ppt is now firmly established as an important and often obligatory part of proposing or launching any development project. Participation: An appropriate and timely access to the process for all interested parties.
A map or series of maps is often required. Impact assessment and evaluation; iv. The officer may go outside his agency to other agencies with the expertise in the field of activity for comments. This effluent passes into the clarifier where the sludge settles at the bottom and the clear water separates at the top. Probable Construction period impacts - economic impacts could be substantial, employment for construction employees, construction materials purchased, equipments - all have impacts on the economic base. The Sewage Treatment Plant systems are modular in design meaning that the treatment tanks are banked up to suit the application.
Site Characteristics: i Whether the site is susceptible to floods, earth quakes and other natural disasters?

Population growth, rising expectations and technological changes have created serious environmental problems. Decision maker: Designated individual or group. In offices and factories where occupants are only there during working hours, the sizing will be different to domestic homes and this must be taken in to account. Practicality: The information and outputs provided by the assessment process are readily usable in decision making and planning. Accountability: The decision makers of all parties are responsible for their action and decisions under the assessment process.
Environmental assessment is taken up in this exercise as a rapid assessment technique for determining the current status of the environment and identifying impact of critical activities on environmental parameters. The environmental impact of the proposed action 2. In view of the fact that development is an ever-growing process, its impact on the environment is also ever increasing, leading to rapid deterioration in environmental conditions. Noise- loud noise is a pollutant d. In addition, if environmental effects are considered at regional level, then cumulative environmental effects of all the projects within the region can be accounted. It is a formal study process used to predict the environmental consequences of any development project.
The environmental performance indicators can be further divided into two categories namely, operational performance indicators and management performance indicators. Transportation systems - existing roads, railways etc b. Irreversible or Irretrievable damage or commitments - An irreversible use of resources is one where the resources that get used in the construction of the project cannot be fully restored physically. This approach facilitates adequate integration of economic development with management of renewable natural resources within the carrying capacity limitation to achieve sustainable development. Thus environmental issues must be addressed as soon as possible during project planning.
In order to try to balance these two goals, we must know the effects of proposed actions or projects and the level of risk acceptance to the public. Many groups are concerned with assessing the degree to which various components of the environment are changing. Locational Alternative - alternative location available that may be owned by the agency proposing to undertake the project C. The educational role is equally important to educate everyone involved both professionals and users. Impact mitigation and monitoring; v.
