What NORM Is and Where It Collects
NORM is naturally occurring radioactive material brought up with produced water. When brine, scale, and sludge build up, radium concentrates: EPA's TENORM material describes scale inside pipe and equipment, sludge in tanks, and filters. The radioactivity is real but low-level; the hazard is handling and disturbing it without controls.
The Exposure Standards That Apply
OSHA's ionizing radiation standard, 29 CFR 1910.1096, sets whole-body dose limits and posting, monitoring, and PPE expectations for employees who could be exposed. States regulate NORM waste handling and disposal, with Texas and North Dakota running the most detailed programs for oil and gas.
Screening, Handling, and Disposal
The practical program: survey tanks and pipe work where scale is known, keep workers out of scale-affected vessels without a plan, control dust and cuts, and dispose of scale and sludge through permitted routes rather than routine landfill. The question is not whether a battery has NORM but whether anyone has looked.
The record that closes the loop
NORM in the Oilfield rests on the same field data as the rest of the operation: tickets, timesheets, approvals, and inspections. The same discipline shows up in Produced water hauling economics and Saltwater disposal well operations and Drill cuttings waste management. If those records live in notebooks, email, and memory, start with an operations audit.
