2009 AOC. Within sixty (60) days of receiving EPA’s approval for Interim Combined AMD Treatment in accordance with Section IV.C.3 of this Agreement, Atlantic Richfield shall request that EPA modify Paragraph 50.i.iii and/or Paragraph 50.j.i of the 2009 AOC (or any provision of a superseding administrative order imposing the same or substantially similar requirements) to terminate Atlantic Richfield’s obligation to capture and treat AMD flows from any Managed AMD Discharge Point included within such approval. The Regional Board shall support Atlantic Richfield’s requests in good faith. The Parties shall not propose or seek to modify the 2009 AOC in a manner that expands the AMD capture and treatment requirements and responsibilities. If the Aspen Seep does not become a part of the Interim Combined AMD Treatment, its collection and treatment will remain the responsibility of Atlantic Richfield in accordance with the 2009 AOC, or any modification thereof, until commencement of the Remedial Action.
