(a) An operator shall submit environmental documentation to the EPA for review. The EPA, in consultation with other interested federal agencies, will carry out a review to determine if the submitted environmental documentation meets the requirements of Article 8 and Annex I of the Protocol and the provisions of this part. The EPA will provide its comments, if any, on the environmental documentation to the operator and will consult with the operator regarding any suggested revisions. If EPA has no comments, or if the documentation is satisfactorily revised in response to EPA's comments, and the operator does not receive a notice from EPA that the environmental documentation does not meet the requirements of Article 8 and Annex I of the Protocol and the provisions of this part, the operator will have no further obligations pursuant to the applicable requirements of this part provided that any appropriate measures, which may include monitoring, are put in place to assess and verify the impact of the activity. Alternatively, following final response from the operator, the EPA, in consultation with other federal agencies and with the concurrence of the National Science Foundation, will inform the operator that EPA finds that the environmental documentation does not meet the requirements of Article 8 and Annex I of the Protocol and the provisions of this part. If the operator then proceeds with the expedition without fulfilling the requirements of this part, the operator is subject to enforcement proceedings pursuant to sections 7, 8, and 9 of the Antarctic Conservation Act, as amended by the Act; 16 U.S.C. 2407, 2408, 2409, and 45 CFR part 672.

(b) The EPA may waive or modify deadlines pursuant to this part where EPA determines an operator is acting in good faith and that circumstances outside the control of the operator created delays, provided that the environmental documentation fully meets deadlines under the Protocol.
