ELG (Effluent Limitations Guidelines)

A federal permit required to move oversized or overweight loads on public highways. Subcontractors hauling heavy equipment or modular components must obtain this before mobilising. Non-compliance can result in fines, delays, and project shutdowns.

A client- or prime contractor-maintained registry of pre-qualified suppliers and subcontractors eligible to bid on work. Getting onto an AVL often requires submitting safety records, insurance, and certifications in advance. Without AVL status, subcontractors are typically blocked from receiving purchase orders or contracts.

Human-caused ground tremors triggered by oilfield operations like hydraulic fracturing or wastewater disposal. Regulators may issue stop-work orders, directly halting your field operations. Subcontractors should track local seismic thresholds, as exceeding them can suspend permits and delay project timelines.

A privately maintained access road built to reach remote work sites in oil & gas or forestry operations. Subcontractors must follow strict user agreements covering speed limits, radio protocols, and load restrictions. Non-compliance can result in access suspension, halting your crew's ability to reach site.

Land or mineral rights owned and managed by the federal government where drilling or construction activity requires federal permits and approvals. Subcontractors working on federal acreage must meet stricter regulatory requirements than on provincial or private land. Expect longer permitting timelines and additional compliance obligations that can affect project schedules and mobilisation.

The U.S. federal agency that regulates the entry of workers, equipment, and materials across the Canadian-American border, which subcontractors must navigate when mobilising crews or hauling specialised equipment into U.S. job sites. Non-compliance with CBP requirements can result in delays at the border, seized equipment, or crews being turned away, making proper documentation and advance planning critical for cross-border field work.
