Dutch term (edited): Vergunning Immissie Punten (VIP�s)

In the context, IMO the VIPs are points at which the noise level is measured for purposes of the licence or permit. Presumably they have been given the designation 'VIP' in some sort of regulatory document or policy document as a short of jargon.

Properly speaking, in the context of environmental protection 'immission' is the 'concentration' of a nuisance (noise, light, odour, etc.) in the environment. It is thus the result of an 'emission' in a given environment. However, the term is relatively new and uncommon in English, and it is often incorrectly used or understood as a synonym of 'emission'.

What the text says is that as most of the locations that could be expected to be affected by the noise generated by the licensed facility are (relatively) far away, locations (immission points) close to the facility have been chosen to serve as the basis for enforcing the noise regulations (presumably the locations defined for measuring the noise level).
