New Mexico requires 2 working days of advance notice to New Mexico 811 before excavating. The law is the Excavation Damage to Pipelines and Underground Utility Lines Law (NMSA 62-14-1 et seq.), implemented by PRC rule 18.60.5 NMAC.
Within 18 inches of a marking, the rule requires exposing the facility by non-mechanical means or vacuum excavation.
Tolerance Zone
18 inches
Within 18 inches either side of a marking, the facility must be exposed by non-mechanical means or vacuum excavation (18.60.5.15 NMAC); the statute requires an estimated 18-inch clearance between marked facilities and mechanical equipment until exposure.
