ATTN: .Mr. Alan S. Hanson President One North broadway White Plains, New York 10601 Gentlemen:

When we sent you Materials License No. SNM-1976, we inadvertently left out the enclosed annex to the license, " Guidelines for Decontamination of Facilities and Equipment Prior to Release for Unrestricted Use or Termination of Licenses for Byproduct, Source, or Special Nuclear Material." Please insert this in the package which we sent you dated September 10, 1987. We apologize for any inconvenience this may have caused.

Sincerely,

?!A ELDa1 Signed by W ukk

t The instructions in this guide, in conjunction with Table 1, specify the radionuclides and radiation exposure rate limits which should be used in decontamination and survey of surfaces or premises and equipment prior to 4 f abandonment or release for unrestricted use. The limits in Table 1 do not

a 3 ply to premises, equipment, or scrap containing induced radioactivity for ,

w11ch the radiological considerations pertinent to their use may be different. l The release of such facilities or items from regulatory control is considered 3 on a case-by-case basis.

1. The licensee shall make a reasonable effort to eliminate residual contamination. 1

2. Radioactivity on equipment or surfaces shall not be covered by paint, plating, or other covering materia 1'unless contamination levels, as  ;

determined by a survey and documented, are below the limits specified (

in Table 1 prior to the application of the' covering. A reasonable effort l must be made to minimize the contamination prior to use of any covering.

3. The radioactivity on the interior surfaces of pipes, drain lines, or ductwork shall be determined by making measurements at all traps, and other appropriate access points, provided that contamination at these locations is likely to be representative of contamination on the interior of the pipes, drain lines, or.ductwork. Surfaces of premises, equipment, or scrap which are likely to be contaminated but are of such size, construction, or location as to make the surface inaccessible for purposes of measurement shall be presumed to be contaminated in excess of the limits. a I

4. Upon request, the Commission may authorize a licensee to relinquish I possession or control of premises, equipment, or scrap having surfaces-  !

contaminated with materials in excess of the limits specified. This may include, but would not be limited to, special circumstances such as razing 1 of buildings, transfer of premises to another organization continuing work with radioactive materials, or conversion of facilities to a long-term storage or standby status. Such requests must:

a. Provide detailed, specific information describing the premises, I equipment or scrap, radioactive contaminants, and the nature, extent,. '

and degree of residual surface contamination.

b. Provide a detailed health and safety analysis which reflects that the residual amounts of materials on surface areas, together with other considerations such as prospective use of the premises, equipment, or scrap, are unlikely to result in an unreasonable risk to the health and safety of the public.

5. Prior to release of premises for unrestricted use, the licensee shall make a comprehensive radiation survey which establishes that contamination is within the limits specified in Table 1. A copy of the survey report-shall be filed with the Division of Industrial and Medical Nuclear Safety, !

U. S. Nuclear Regulatory Conr11ssion, Washington, .DC 20555, and also the Administrator of the NRC Regional Office having jurisdiction. The report j should be filed at least 30 days prior to the planned date of abandonment. l The survey report shall:

a. Identify the premises. f i

b. Show that reasonable effort has been made to eliminate residual j contamination.

c. Describe the scope of the survey and general procedures followed. ,

i

d. State the findings of the survey in units specified in the instruction. ,

Following review of the report, the NRC will consider visiting the facilities to confirm the survey. ]
