What are the changes to ENB 4.15?

Environmental Services is proposing an update to Administrative Rule ENB-4.15 (Environmental Services' Enforcement Program) to address a drafting error in a July 2019 rulemaking. The changes proposed are limited to one sentence under Section 9 of ENB-4.15 (Administrative Review). The proposed language matches provisions already in other rules revised in July 2019, regarding the timing of issuance of written final determinations for administrative reviews of Environmental Services decisions. The proposed language includes:

  • Changing the default timeline for issuance of a final determination after an administrate review meeting from 10 business days to 15 business days.
  • Revising the same sentence to include an opportunity for Environmental Services to extend the time line to issue a final determination if Environmental Services determines that extenuating circumstances justify a reasonably longer period of evaluation.
  • The sentence was revised to include, “unless BES determines that extenuating circumstances justify a reasonably longer period of evaluation” and removed “unless an extension is agreed to by all parties."

No other changes are proposed.
