Federal Register :: Constraint on Releases of Airborne Radioactive Materials to the Environment for Licensees Other Than Power Reactors
https://www.federalregister.gov/d/2012-9998 https://www.federalregister.gov/d/2012-9998
The U.S. Nuclear Regulatory Commission (NRC) is issuing a revision to Regulatory Guide (RG) 4.20, “Constraint on Releases of Airborne Radioactive Materials to the Environment for Licensees other than Power Reactors.” This RG provides guidance on methods acceptable to the NRC's staff for meeting the constraint on airborne emissions of radioactive material to the environment.

The ADAMS accession number for each document referenced in this notice (if that document is available in ADAMS) is provided the first time that a document is referenced. Revision 1 of RG 4.20 is available in ADAMS under Accession No. ML110120299. The regulatory analysis may be found in ADAMS under Accession No. ML110120351.
Revision 1 of RG 4.20 was issued with a temporary identification as Draft Regulatory Guide (DG)-4018. This RG provides guidance on methods acceptable to the NRC staff for meeting the constraint on airborne emissions of radioactive material to the environment as described in Title 10 of the Code of Federal Regulations (10 CFR) 20.1101(d). In 1996, the NRC added a constraint to 10 CFR part 20, “Standards for Protection Against Radiation,” to remove dual regulation by the NRC and the U.S. Environmental Protection Agency and to provide an “ample margin of safety” to members of the public from airborne emissions of radioactive material to the environment.
In 10 CFR 20.1101(d), the NRC states the following:
To implement the ALARA (as low as is reasonably achievable) requirements of § 20.1101(b), and notwithstanding the requirements in § 20.1301 of this part, a constraint on air emissions of radioactive material to the environment, excluding radon-222 and its daughters, shall be established by licensees other than those subject to § 50.34a, such that the individual member of the public likely to receive the highest dose will not be expected to receive a total effective dose equivalent in excess of 10 mrem [millirem] (0.1 mSv [millisievert]) per year from these emissions. If a licensee subject to this requirement exceeds this dose constraint, the licensee shall report the exceedance as provided in § 20.2203 and promptly take appropriate corrective action to ensure against recurrence.
The NRC staff examines licensee programs to determine whether they comply with the requirements in 10 CFR part 20. This guide addresses only a part of a licensee's overall radiation protection program. Specifically, it addresses methods that licensees can use to demonstrate that they meet the constraint on airborne emissions of radioactive material to the environment. In addition to controlling doses from airborne emissions of radioactive material to the environment, licensees must implement a radiation protection program that controls liquid effluents and dose rates in unrestricted areas.
On April 20, 2010 (75 FR 20645), DG-4018 was published in the Federal Register and it was reopened for a 60-day public comment period on June 25, 2010 (75 FR 36445). The public comment period closed on August 23, 2010. The Federal Register notice (FRN) dated June 25, 2010 (75 FR 36445), inadvertently cited the ADAMS accession number for the original FRN noticing the issuance of DG-4018 (75 FR 20645; ADAMS Accession No. ML092600090) in place of the ADAMS accession number for DG-4018 (ADAMS Accession No. ML092590180). However, the original FRN noticing the issuance of DG-4018 (75 FR 20645; ADAMS Accession No. ML092600090) cited the correct ADAMS accession number for DG-4018.
