8.4 Risk Assessment Results Risks identified were assessed using the methodology described above and considered the activities subject to these proposed amendments. The resulting assessment including risk controls and treatments is presented in Table 70. All risks considered existing and proposed controls to reduce the level of risk to ALARP.
