• "EPA requests comment on this proposal."
• "EPA requests comment on these issues."
• "EPA requests comments on ... [end of the sentence]."
• "EPA requests comment on ... [end of the sentence]."
• "EPA also requests comment on ... ."
• "The EPA requests comment on... ."
• "EPA welcomes comments on ... ."
• Bulleted list of questions:
  • "Do commenters [generally] agree...?"
• "Therefore, EPA is requesting comment on ... ."
• "We request comment on this aspect of the proposed rule."
• "we are also soliciting comment on ... ."
• "The Agency solicits comment on these matters."
• "If commenters believe ... " (?)

Turns out, these phrases are relatively specific to the rule. Rather than try a rule-based approach, I'm going to assume that the notice has been marked up ahead of time and build the layer data based on those manual tweaks.
