§ 300.505 EPA/State Superfund Memorandum of Agreement (SMOA).
(a) The SMOA may establish the nature and extent of EPA and state interaction during EPA-lead and state-lead response (Indian tribes meeting the requirements of § 300.515(b) may be treated as states for purposes of this section). EPA shall enter into SMOA discussions if requested by a state. The following may be addressed in a SMOA:
(1) The EPA/state or Indian tribe relationship for removal, pre-remedial, remedial, and enforcement response, including a description of the roles and the responsibilities of each.
(2) The general requirements for EPA oversight. Oversight requirements may be more specifically defined in cooperative agreements.
(3) The general nature of lead and support agency interaction regarding the review of key documents and/or decision points in removal, pre-remedial, remedial, and enforcement response. The requirements for EPA and state review of each other's key documents when each is serving as the support agency shall be equivalent to the extent practicable. Review times agreed to in the SMOA must also be documented in site-specific cooperative agreements or Superfund state contracts in order to be binding.
