(B) Consideration In the evaluations required in a plan under subparagraph (A), the regulations promulgated by the Secretary shall ensure that the distribution integrity management plan evaluates for future potential threats in a manner that considers factors other than past observed abnormal operations (within the meaning of section 192.605 of title 49, Code of Federal Regulations (or a successor regulation)), in ranking risks and identifying measures to mitigate those risks under that subparagraph, so that operators avoid using a risk rating of zero for low probability events unless otherwise supported by engineering analysis or operational knowledge. (C) Deadlines (i) In general Not later than 2 years after the date of enactment of this paragraph, each operator of a distribution system shall make available to the Secretary or the relevant State authority with a certification in effect under section 60105, as applicable, a copy of— (I) the distribution integrity management plan of the operator; (II) the emergency response plan under section 192.615 of title 49, Code of Federal Regulations (or a successor regulation)
