Changes to SECY-99-046 Chanaes to the Federal Reaister notice:
i 1.
On page 8, last line hsert ' radioactive' after ' occurring'so that the sentence reads: "The
)
5 pCi/g radium value has also been recommended as an exemption level by the Board of
- Directors of the Conference of Radiation Control Program Directors (October 1998) for the Suggested State Regulations on technologically enhanced naturally occurring radioactive materials.
2.
On page 9, change the first sentence as follows: "The NRC staff's preliminary dose modeling, using realistic parameter values and the RESRAD code, indicates that at typical UR facilities, where the background raaiation results in doses of over 200 mrem /yr (2.0 mSv/yr), the Ra-226 standard of 5 pCi/g (0.19 Bq/g) could typically result in a potential peak annual dose on the order of 20 to 35 mrem /yr (0.2 to 0.35 mSv/yr) to the average member of the critical group 3.
On page 9,~ paragraph 2 line 4, insert a new sentence prior to the start of the third -
sentence as follows: "Also, EPA,modeled a much smaller frachon of time an individual would. spend outdoors (0.02 versus 0.25) and used a less. con.servative root depth.value (0.g versus 0.25 meters) which generally decreases the calculated potential dose.
4.
On page 10, change the next to the last sentence in the first partial paragraph as follows:
"The rule text and guidance also stipulate that the total effective dose equivalent limit is
- based on the mammum peak annual dose within a 1000 year period to the average member of the critical group.
5.'
On page 12, paragraph 2, line 3, Uelete the 'm' in 'O.1 mSv/yr'.
6.
On page 18, change the last sentence to read: "The.use of decommissioning, plans with benchmark doses which exceed;100 mrom/yr,)slore apphcahon.of Al. ARA, requires.the -
approval of the Commission after consideration of the recommendation..of the NRC staff."
Chanaes to the Public Announcement 7f On page 1, paragraph 3, revise the first 2 sentences as follows: "The new dose criteria
- are based on the existing Environmental Protechon A0ency (EPA) soil standard for radium'. The EP6EnvemnmenteH4etechteAgency previously set standards requiring that the concentration of radium at uranium mills after decommissioning may not exceed the natural background levels of radiation by more than 5 picocuries'per gram in the first
. 6 inches of soil, and 15 picocuries per gram for every subsequent 6-inch layer."
8.
. On page 1, paragraph 4, change the first sentence as follows: "The new standard for uranium and thorium uses the radiation dose from radium in soil as a benchmark." In line 2, change ' facility' to ' facilities'.

1 9.
On page 2, line 2, add the following new sentence at the end of the paragraph: "The staff t
recently calculated that the potential dose to an individual from applying the benchmark approach may range between 22 and 34 millirem per year."
10.
On page 2, revise the last paragraph as follows: "In the unlikely event that appliation of this benchmark would result in a dose exceeding 100 millirems per year, the staff will consult with and receive the approval of the Commission before approving the decommissioning plan. C;,T..nl;;;;. ;.ill epec;f;ce"y rev: J; the situ;t;sn. The 100-millirem dose is the NRC annuallimit for members of the public. The average annual dose to an individual in the United States from naturalm background radiation is about 300 millirems."
i Chanoes to the Conaressional letters 11.
In line 1, insert 'U.S.' prior to ' Nuclear" so it reads: "The U.S. Nuclear Regulatory Commission (NRC) has sent to the Office of the Federal Register for publication. "
12.
In the last line, insert ' unique' before ' issues'so it reads: ". and instead request additional public coment so as to provide full consideration of the unique issues involving decommis; uning of UR facilities."
i Chanaes to the Letters to Gore. Murohv. and Hastert 13.
In fina 2, insert 'U.S.' prior to ' Nuclear" so it reads: ".. the U.S. Nuclear Regulatory Commission (NRC) is submitting a final rule regarding decommissioning...
