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
