DNV Scope of work for Gascan

1. Evaluate if the content of the Environmental Impact

Assessment (EIA), performed for the LNG regasificationterminal, covers all aspects required for a project of this typeand dimension.

2. Assessment of best location for the LNG terminal, based on

information given in the EIA

a site survey carried out by DNV at Gran Canaria and Tenerife

Arinaga

Tirajana

La Isleta

Arguïneguin

Granadilla

Santa Cruz de Tenerife




Environmental review of energy sources

Increased demand of energy in thefuture

Today; electricity generated fromheavy oil and diesel fuelled powerplants and 6-7% from wind farms

Wish to convert to moreenvironmental friendly energyresources:

- Coal dismissed by political decision

- Wind energy can contribute to max.

20% of the demand due to regularityrequirements

- Natural gas a logical choice

Evaluation of EIA

Purpose with EIA

- Provide relevant authorities with information enablingthem to evaluate the projects environmental, societaland health impacts

- Ensure that environmental issues provide decisionsupport

- Shall cover direct and indirect effects, short and long

term effects, permanent and temporary, as well aspositive and negative impacts.

- The EIA should fulfil requirements of local Canarian,Spanish and EC regulations and Directives

- EU Directive on Environmental Impact Assessment

(Council Directive 97/11/EC of 3 March 1997) isimplemented in Spanish regulations.

- Requirements of an EIA is dependent on thecharacteristics of the potential impacts

Conclusions of DNVs EIA evaluation

According to common industrial practice

According to both national and EU regulations and requirements

Good description of present conditions (geological, vegetation, fauna,flora, landscape etc.)

- The description is based on existing literature and sensitivity maps

Impacts from both construction and operational phase outlined

Includes a realistic prediction and valuation of impacts




Assessment of alternative locations

Assessment criteria:

- Should not affectenvironmental protectedareas

- Should not affectenvironmental sensitiveareas

- Utilization of establishedinfrastructure

- Distance to power plantshould be minimised

- Physical and visual impacts

General:

- Coastal strip of GranCanaria is plain and largestructures are visual fromgreat parts of the district

-Arguineguin

-Arinaga

- Tirajana(existingpower plant)

-La Isleta

The assessment is based on the EIA report and on a site survey conducted by DNV




Location Arinaga

☺ Advantages:

- Regulated as an industrial estate- New harbour will be developed

independent of location of LNGterminal

- Relatively short distance to power

plant

Disadvantages:

- Marine site of importance for thecommunity (LIC) to the north ofthe planned harbour

- IBA area




Location Tirajana

☺ Advantages: Disadvantages:- Proximity to power plant - IBA area

- Industrial area - No existing harbour




Location La Isleta

Harbour and jetty LNG Terminal

☺ Advantages: Disadvantages:

- None - Protected area

- Long distance to power plant

- No harbour and infrastructure




Location Arguineguin

☺ Advantages:

- Existing harbour, but need tobe expanded

Disadvantages:

- Harbour in the middle of thecity

- Long distance to power plant




Tenerife

Selected location: Granadilla

- Industrial estate- Proximity to power plant

- Not classified as protected orsensitive area

- Impacts outside harbour area

considered insignificant

Alternative locations:

- North of the power plant: fromenvironmental point of view, nochanges in impact

- Other locations on the islandlimited due to:

- Topography

- Protected/sensitive areas

- Longer distance to power plant




Conclusion

Emissions to air will be significantly reduced due to changing to naturalgas in the power plant.

Based on overall evaluation of environmental impacts, the proposedlocation both on Gran Canaria and Tenerife is found to give minorimpacts to natural resources.
