Special Economic Zone notification empowers central government to notify areas and authorise developers to operate within SEZs. After grant of the letter of approval under section 3(10), the Developer must submit exact particulars of the identified area to the Central Government, which may, after satisfying itself that section 3(8) and prescribed requirements are fulfilled, notify that area as a Special Economic Zone; existing SEZs are deemed notified and the Central Government may subsequently notify additional areas for inclusion. After the appointed day, the Board may authorise the Developer to undertake in a SEZ such operations as the Central Government may authorise.
