• Negligent violation – producers must dispose of
  plants that exceed the acceptable hemp THC level. However, if the plant
  tests at or below the negligent threshold stated in the rule, producer
  will not have committed a negligent violation. The final rule raises the
  negligence threshold from .5 percent to 1 percent and limits the
  maximum number of negligent violations that a producer can receive in a
  growing season (calendar year) to one.
• Disposal and remediation of non-compliant plants –
  the final rule allows for alternative disposal methods for
  non-compliant plants that do not require using a DEA reverse distributor
  or law enforcement and expands the disposal and remediation measures
  available to producers. AMS will provide acceptable remediation
  techniques in a separate guidance document.
• Testing using DEA-registered laboratories – there
  are an insufficient number of DEA-registered laboratories to test all
  the anticipated hemp that will be produced in 2020 and possibly 2021.
  DEA has agreed to extend the enforcement flexibility allowing non-DEA
  registered labs to test hemp until January 1, 2022 and is processing lab
  registration applications quickly to get more labs testing hemp
  DEA-registered.
• Timing of sample collection – the IFR stated a 15-day window to collect samples before harvest. The FR extends this requirement to 30 days before harvest.
• Sampling method – stakeholders requested that
  samples may be taken from a greater part of the plant or the entire
  plant. They also requested sampling from a smaller number of plants. The
  FR allow states and tribes to adopt a performance-based approach to
  sampling in their plans. The plan must be submitted to USDA for
  approval. It may take into consideration state seed certification
  programs, history of producer compliance and other factors determined by
  the State or Tribe.
• Extent of Tribal Regulatory Authority over the Territory of the Indian Tribe
  – the IFR did not specifically address whether a tribe with an approved
  USDA plan could exercise primary regulatory authority over the
  production of hemp across all its territory or only lands over which it
  has inherent jurisdiction. The final rule provides that a tribe may
  exercise jurisdiction and therefore regulatory authority over the
  production of hemp throughout its territory regardless of the extent of
  its inherent regulatory authority.
