Abstract: We prove Bloch’s formula for the Chow group of 0-cycles with modulus on a smooth quasi-projective surface over a field. We use this formula to give a simple proof of the rank one case of a conjecture of Deligne and Drinfeld on lisse $\overline {\mathbb {Q}}_{\ell }$-sheaves. This was originally solved by Kerz and Saito in characteristic $\neq 2$.
