Table of contents What is environment engineering.

Environmental impact analysis

Different steps of Environmental impact

How to conducted the Environmental Assessment

Engineer philosophy Public verdict .

1. Know about the problem.

2. Create new techniques.

3. Evaluate the alternatives .

4. Implementation of new one

5. Periodical and reconsideration of executed

Environmental Impact What is NEPA?Council of Quality Environment 1. Monitoring all the federal Activities.2. To evaluate these problems3. Elucidation to these problems

What people think in 1970 about NEPA?• how much impact of proposed action on environment• Any adverse environmental effect• Alternative to proposed actions• Relationship between local short term(man’s environment) and long term productivity• Commitments of reosuces.

Certified project FONSI Potential environment impact are compared with the significant check list impacts

Environmental Assessment Detail assessment of Environmental impact

Environmental Impact Statement(EIS)

Environmental impact of both proposed and alternative actions.

Its sequence is described by the law

1. First issued the Draft EIS by federal agency

2. Then issued a final EIS after hearing and including comments.

these are assessment reports not judgment

these are assessment reports not judgment

Record of decision(ROD)

final decision about action proposed , alternatives and any valuable judgments “justify or faulty the projects” difficult to apply Environment assessment procedure include the socio-economic pattern

1. In economic section it include the no. of jobs , income and property value.

2. Include the archaeological and historical impacts.

Engineer must take care about the quantitative measurable impact and qualitative assessment.

Environment assessment 1. Scoping : scope or extent of the assessment. One public

hearing is generally held on scoping.

2. Inventory : Susceptible area and activities also socioeconomic.

3. Assessment : Impact of both proposed and alternatives , cumulative.

4. Evaluation : interpretation of these findings.

federal agencies must inspect the individual and extended programme and projects

Generic environmental impact statement( GEIS)

programmatic environmental impact statement (PEIS).

Environmental Inventories Project alternatives inventory factors

1. the “ologies”

2. Environmental quality

3. Plant and animal life

4. Economic impact

5. Analysis of the risks

6. Relevant Socio-economic Parameter

The process of calculating projected effects that a proposed action or construction

project will have on environmental quality is called environmental assessment.

both have same procedure but different effects.

Checklist are both primary and 2ndry effects on environment.

The highway project have three phase PlanningConstructionoperation

Used arbitrary scale for impact factor
