| Question | Answer |
| Direct & indirect impact | Direct: Direct interaction of an activity Indirect: One impact Will activate another impact |
| Steps i EIA | 1: screening 2: scoping 3: assessing 4: mitigation 5: reporting/ monitoring 6: reviewing/auditing |
| What is EIA | Environment impact assessment It's an activity to identify the impacts a project can have on a society & find solutions to minimize the impacts |
| What is EIS | Environment impact statement A document required which state out the positive and negative impacts the project have. May list alternative action |
| What is EI | Environment inventory Complete list over the environment as it is now, before project |
| What is FONSI? | Finding of no significance impact A document which state out way the EIS is not required. |
| What is the objective of EIA? | Predict the impacts in an early stage Fulfill the responsibilities of each generation to come Assure safety for all citizens & surroundings Attain widest range of beneficial users without degradation |
| Sceening | Determine if the project have any effects on the environment & therefor require an assessment |
| Scoping | Determine the extent of issues to be considered Here the locals can be asked (scoping opinion) |
| Assessing | Impact identification, analyze/ predict Environment impacts |
| Mitigation | Redesign: finding solution to problem EMP: Env. management plan (guide to improvements) |
| IEE Initial environmental examination | Reviewing the environmental integrity used for project screening. Which project require a full scale EIA |
| What is an impact | It's change that can be beneficial or not, & is brought by an activity |
| Assessment | Evaluation and estimation of the impact |
| Steps in full scale EIA | Scope (range of impacts) Identify (existing env. Determine components) Predict (define quantity & estimate probability) Evaluate ( who will be affected?) |
| Planning & management of impact studies | Enter text here... |
| How do you evaluate the overall significance of impacts? | (Mode+area+type+duration)x frequency or probability of occurrence |
| Types of EIA | Site selection studies Rapid or comprehensive studies Regional studies Carrying capacity studies |
| Site selection studies | Proximity to raw materials, infrastructure & markets etc. |
| Rapid or comprehensive studies | Rapid: One season monitoring Comprehensive: 3 season studies |
| Regional studies | Capacity of air, water & land components |
| Carrying capacity studies | Resources availability |
| Cumulative impact | Created as a result of the combination of the projects |
| Induced impacts | ? |
| Criteria for selecting EIA methodologies | 1.General 2. Impact identification 3. Measurements 4 interpretations & evaluation 5. Communication |
| General | Simplicity Manpower time & budget constrain Flexibility |
| Impact identification | Comprehensive Specification Isolation of project impact Timing & duration: identify location & extent on temporary scale |
| Impact measurements | Commensurate units: comparing Explicit indicators Magnitude Objective criteria |
| Impact interpretation & evaluation | Significance Explicit criteria Portrayal of with & without situation Uncertainty Risk Depth of analyse Alternative comparison Public involvement |
| Impact communication | Affected parties Setting description Summary format Key issues Compliance |
| Ad hoc method | Assembling of a team of specialist to identify impacts in their area Rough assessment |
| Different kinds of checklists | Simple: no guidelines on how to measure Descriptive: have guidelines Scaling: yes/no/ maybe |
| Network method | Identifying direct & indirect impacts Writhing and rating of impacts not featured |
| What does Matrices display | Action & appropriate env. Factors |
| Types of matrices | Leopold matrix Stepped matrix Simple matrices |
| Leopold matrix | 100 specified actions & 88 environmental items Step 1: identify all actions 2: |
| Stepped matrix | Address 2. & 3. Impacts Env. Factors displayed against other factors Remits: affected env. Not described properly |
| Conceptual framework | List out env. Factors Apply selection proces Selected list of env. Factors Procure data& conduct baseline study Prepare description |
| Assessment of air pollution impacts proces | 1:identification of impact 2:description of existing env. 3:procurement of relevant air quality & guidelines 4:impact prediction 5:Assessment of impact significant 6:Identification & incorporation-mitigation |
