Policy Compendium

15.c) "[The World Heritage Committee encourages States Parties to] (…) be proactive in relation to development and conservation of World Heritage properties by conducting a Strategic Environmental Assessment (SEA) at the time of nomination to anticipate the impact of any potential development on the Outstanding Universal Value."

Paragraph 163

“A minor modification is one which has not a significant impact on the extent of the property nor affects its Outstanding Universal Value.”

Paragraph 164

“If a State Party wishes to request a minor modification to the boundaries of a property already on the World Heritage List, it must be prepared in compliance with the format of Annex 11 and must be received by 1 February by the Committee through the Secretariat, which will seek the evaluation of the relevant Advisory Bodies on whether this can be considered a minor modification or not. The Secretariat shall then submit the Advisory Bodies’ evaluation to the World Heritage Committee. The Committee may approve such a modification, or it may consider that the modification to the boundary is sufficiently significant as to constitute a significant boundary modification of the property, in which case the procedure for new nominations will apply.”
