Loss of Containment
ComplianceAn unplanned release of a hazardous substance — liquid, gas, or solid — from piping, vessels, or equipment. For subcontractors, an LOC incident can trigger immediate work stoppages, site investigations, and liability exposure. Proper reporting and response procedures are typically required under your prime contractor agreement.
DBE (Disadvantaged Business Enterprise)
ComplianceA certification recognising businesses owned by minorities, women, or economically disadvantaged individuals. Prime contractors on federally funded projects often must subcontract a percentage of work to certified DBEs. Holding DBE status can open doors to set-aside contracts and preferred bidder programmes.
API (American Petroleum Institute)
ComplianceThe leading industry organisation that develops technical standards, safety protocols, and equipment specifications that subcontractors must follow when working on oil and gas projects. API certifications and compliance with API standards are often mandatory requirements in service contracts and can affect your ability to bid on projects.
Protest (customs)
ComplianceA formal dispute filed against a customs ruling, such as import duties charged on tools or equipment crossing the border. Subcontractors use protests to recover overbilled duties on temporarily imported gear. Filing deadlines are strict, so act quickly after receiving a customs decision.
DOE (Department of Energy)
ComplianceA U.S. federal agency that regulates energy production, sets safety standards, and oversees projects involving nuclear, fossil fuel, and renewable energy. Subcontractors working on DOE-funded or DOE-regulated sites must meet strict compliance and security requirements. Contracts tied to DOE projects often include additional reporting obligations and certified personnel requirements.
811 (call Before You Dig)
