Ms Alison Hough:

In the case of a no-deal Brexit, the European Court of Justice would lose jurisdiction over what happens on the north side of Carlingford Lough but we are still responsible for what happens on the south. Potentially, pollution from the north side of Carlingford Lough could result in an infringement for Ireland, incurring fines and liability, etc. I am referring to circumstances in which we lose control over a portion of our environmental integrity.
