Environmental Engineering Decision Objectives Description of Technical Analysis

Environmental Engineering Decision

Objectives • Description of Technical Analysis Decision • Cost Effectiveness Analysis Decision • Benefit /Cost Analysis Decision • Risk Analysis Decision • Environmental Impact Analysis Decision

Engineering Decision Based on Technical Analysis 1 - Assumption should be made for first stage since the technical analysis will be vary EX. SW trucks A and B have sufficient capacity to haul the waste only operation and maintenance cost might be very different.

Engineering Decision Design basd on Cost Effectiveness Analysis 1 - compare the cost of different alternatives based on a- Annual cost : annually operating facility cost b- present worth: the funds needed to construct the facility.

Engineering Decision Based on Benfits/ Cost Analysis convert most of the facility items to monetary items. Check which items are giving some benefits in comparison with remaining items.

Engineering Decision Based on Risk Analysis -Define the type and source of pollutant - Identify the pathways & rate of exposure. How can it get to human and cause health problem - Decide what impact is acceptable what effect is considered

Engineering Decision - Estimate the maximum allowable emission or discharge. - if the emission or discharge higher than the maximum allowable, determine what technology needs to achieve max allowable emission or discharge

Engineering Decision Based on Environmental Impact Ananalysis EIA report has to be prepared , report include: 1 - Inventory Data gathering in this stage such as biological, chemical and physical data. This stage doesn’t include any discussion. Collecting Data will be implement for assessment level

Engineering Decision 2 - Assessment mechanism will estimate the following: - Importance of the impact. - Magnitude of the impact. - Nature of the impact.

Engineering Decision 3 -Evaluation Last stage is evaluation stage where conclusion and recommendation will take place here. The final conclusion and recommendation will be built in base of the inventory and assessment steps.
