Sensitivity assessments Constraint Environmental

Very High Area is rated as being extremely sensitivity to development. As a result the area will either have very high conservation or socio-economic value

High Area is rated as being highly sensitivity to development.As a result the area will either have high conservation or socio-economic value

Medium Area is rated as being of medium sensitivity to development. As a result the area will either have medium conservation or socio-economic value

Low Ares is considered to have low levels of sensitivity in the context of gas pipeline construction and maintenance

Draft Corridors for Specialist Assessment

Way Forward– Data from specialists to feed into updating the

wall to wall environmental sensitivity

– Reports out for public comment

– Incorporate changes from comment into specialist assessments

– Update data and do Least cost path analyses

– Final reports and analyses available early next year
