The generic assessment methodology employed throughout the PEIR is explained in detail in Chapter 6 EIA Methodology.
The assessment of impacts to Infrastructure and other users has focused on establishing potential for overlaps and, therefore, conflict between activities in both a geographical and temporal context. This information has been obtained through statements made within publicly available literature relating to the activity under question (such as an ES or Scoping Report) or through consultation with the relevant operator of the activity as discussed in section 18.2.
18.4.2.1 Sensitivity 24.
The sensitivity of the receptor for each impact is characterised as one of four levels, high, medium, low or negligible. Examples of definitions for differing levels of sensitivity of infrastructure and other users are provided below in Table 18.7
Table 18.7 Definitions of the Different Sensitivity Levels for Infrastructure and Other User Activities Sensitivity
Definition High
Medium Low
Negligible High sensitivity and limited potential for substitution.
High or mediumsensitivity with limited potential for substitution Low or mediumsensitivity at a local scale Very low sensitivity even at a local scale
