RE: National Primary Drinking Water Regulations; Radionuclides, Proposed Rule;

65 Fed. Reg. 21,575 (April 21, 2000); Water Docket W-00-12.

Dear Comments Clerk:

We are pleased to submit the enclosed comments on the proposed rule of the U.S. Environmental Protection Agency entitled "National Primary Drinking Water Regulations; Radionuclides; Notice of Data Availability," 65 Fed. Reg. 21,575 (April 21, 2000). RSH is an international nonprofit organization of independent experts on radiation and public policy, committed to apply current scientific data and theories to radiation protection policy.

Please call if you have any questions.
