There may be a conflict between the development policies and the presence of the notifiable installations. Any proposed developments should take their presence into account.
You are strongly advised to consult the listed pipeline operator, to confirm the exact location and route of their pipelines in the area covered by the plan and to ensure that your records are kept up to date.
In view of the presence of notifiable installations in the area covered by the plan, it would be helpful to potential developers if the constraints likely to be imposed by their presence were indicated in a policy statement in the plan. The paragraphs in the attached Annex could form the basis of such a statement which may avoid the submission of planning applications containing inappropriate proposals.
In addition, we suggest that the proposals maps be marked to show locations of the notifiable installations consistently with paragraph 6.21 of Department of Environment Circular PPG12. We particulary recommend marking the routes of the notifiable pipelines as, in our experience, most incidents involving damage to buried pipelines occur because third parties are not aware of their presence.
