Torah Temimah cites Zevachim 48a.
“In the place of the olah” — and where is the olah slaughtered? In the north; learn from this that the chatas requires the north.
Semichus / Ribbuy — northern location for the individual’s chatas is both a mitzvah and me’akev (indispensable).
The ordinary individual’s chatas must be slaughtered on the northern side of the Temple courtyard. The derivation from the olah’s northern requirement makes the location both obligatory and indispensable; slaughter elsewhere invalidates the offering. This is one of the places where the Torah’s cross-reference to the olah transfers a spatial requirement to the chatas.
