Surface Impoundment

Informal field term for high-consequence hazards requiring mandatory controls before work begins. For subcontractors, STCKY items typically appear on permit-to-work forms and site safety plans.

A U.S.-based non-profit that develops safety research, training materials, and hazard guides used widely across North American job sites.

A document outlining required inspections, tests, and quality checks at specific project milestones. Subcontractors must follow the ITP to prove work meets client and regulatory standards. Hold points in the plan require client sign-off before work can continue.

Legally required costs to decommission and remediate a site at end of life, such as plugging wells or removing infrastructure.

A formal document a subcontractor submits after a safety incident, audit failure, or contract non-compliance. It outlines specific steps, responsible parties, and deadlines to fix the identified problem. Clients or prime contractors often require approval before field work can resume.
