RG,
It looks like RastaCrab already answered your question. If you would like to reach out to NEPA, you can find all the contact
information you could possibly want by googling "NEPA Jamaica".
If you take the time to read the links that have been posted, especially from the United Nations Environment Program that has the entire Negril area as its pilot project focus and the full Sandals proposal, you would see all your questions from your second post answered as well.
For further information, please feel free to contact NEPA.
