INTRODUCTION TO NORM

• Gaining notice by litigation and public misunderstanding

• Issue developed in the 1980s & 1990s

• Ra226, Ra228, Rn222, & daughter products

WHO REGULATES NORM?

• Railroad Commission of Texas • Disposal Only of Oil & Gas NORM

• Department of State Health Services• Possession, Handling, Worker

Protection,Transportation, etc. – EVERYTHING UP TO DISPOSAL!

• Department of Transportation• Transportation of Radioactive Material

SPECIFIC LICENSEE / GENERAL LICENSEE

• General Licensee - Producers, operators, equipment yards, pipe yards, etc.

• Specific Licensee - A company that applies to and is approved by the regulatory authority for a license to perform NORM work.

• The Gray Area – Is it Routine Maintenance or Decontamination?

HANDLING NORM

• General Licensee – Required to have a NORM Worker Protection Plan; 25 TAC 289.202

• Worker Protection Worker Training – get trained!• NORM Awareness• NORM Worker• NORM Surveyor• Radiation Safety Officer (RSO)

• Secure the location/equipment with notices & signs

RRC MARKING RULE 16 TAC Rule 4.601

• All Operators/Producers in Texas MUST mark their NORM-Contaminated Equipment with the letters “NORM”

• Clearly visible waterproof tag or marking with a legible waterproof paint or ink

• Must be conspicuous to the worker (by the valve, manway, etc.)

SURVEYING TECHNIQUES

• Survey within 1 centimeter of the surface• Check the response of the meter every

time you conduct a survey• Meters must be calibrated every 12

months• Record the results of the survey on a

report or a form with a drawing of the location

• Take Pictures of the Location

EQUIPMENT VS. WASTE

• Vessels/Pipe are Contaminated at 50 µR/hr – • Reading on the equipment determines if a specific

license is required to re-mediate the vessel• Waste/Soil is contaminated at 30 pCi/g of Ra226 &

Ra228 or 150 pCi/g of their daughter products –

• The activity level of the waste determines how the waste must be disposed

TRANSPORTATION OF NORM

• Determine if the load is considered “Radioactive” per DOT – 2 steps

1. Rule of Thumb Calculation - Gamma Spectroscopy• Ra226 % = Analysis / 2,700 pCi/g• Ra228 % = Analysis / 2,700 pCi/g• Th228 % = Analysis / 270 pCi/g• Total % > 100% Radioactive, < 100% Non-

radioactive

2. If Radioactive, survey external package > 500 µR/hr then placard “Radioactive” and manifest with proper shipping name

AUTHORIZED DISPOSAL METHODS

Authorized by Rule• Disposal in plugged &

abandoned wells• Burial (at the same site

where the NORM was generated)

• Land farming (the same site where NORM was generated)

• Disposal at a licensed facility

• Injection (if waste is NOW)

Permit Required• Non-retrieved

Flowlines/Pipelines• Commercial or Centralized

Surface Waste Management Facilities

• Disposal in plugged & abandoned wells

• Injection• Injection in Enhanced Oil

Recovery Injection Wells
