Withdrawal of
the Proposed National Primary Drinking Water Regulation for Radon-222
AGENCY: Environmental Protection Agency.
ACTION: Notice of withdrawal of proposed rule.
SUMMARY: This document announces the Environmental Protection
Agency's (EPA) withdrawal of drinking water regulations proposed for radon-222
(56 FR 33050, July 18, 1991). EPA is withdrawing the proposed Maximum
Contaminant Level Goal (MCLG), Maximum Contaminant Level (MCL), monitoring,
reporting, and public notification requirements for radon-222 as required
by section 1412(b)(13)(A) of Safe Drinking Water Act (SDWA), as amended.
No other provision of the July 18, 1991 proposal is affected by today's
action.
FOR FURTHER INFORMATION CONTACT: Sylvia Malm, (202) 260-0417.
For information on radon in drinking water and other EPA activities under
the Safe Drinking Water Act, please contact the Safe Drinking Water Hotline
at 1-800-426-4791. For information on radon in indoor air, please contact
the National Safety Council's National Radon Hotline at 1-800-SOS-RADON.
SUPPLEMENTARY INFORMATION: On July 18, 1991 (56 FR 33050), EPA
proposed a maximum contaminant level goal (MCLG), a maximum contaminant
level (MCL), monitoring, reporting, and public notification requirements
for radon and a number of other radionuclides in public water supplies
(systems serving over 25 individuals or with greater than 15 connections).
EPA proposed to regulate radon at 300 pCi/L.
On August 6, 1996, Congress passed amendments to the SDWA. Section 1412(b)(13)(A)
of the SDWA, as amended, directs EPA to withdraw the proposed national
primary drinking water regulation for radon. With this Federal Register
document, EPA withdraws the proposed MCLG, MCL, monitoring, reporting,
and public notification requirements for radon-222. No other provision
of the July 18, 1991 proposal is affected by this action.
Congress has directed EPA to propose an MCLG and National Primary Drinking
Water Regulation (NPDWR) for radon-222 by August, 1999 and promulgate
a final regulation by August, 2000 [section 1412 (b)(13)(D-E)]. EPA has
committed to take final action on the other radionuclides included in
the July 18, 1991 proposal by December, 2000. On a related matter, EPA
published on March 5, 1997 (62 FR 10168) a final rule on the analytical
methods for gross alpha, gross beta, tritium, uranium, radium-226, radium-228,
gamma emitters, and radioactive cesium, iodine and strontium.
Dated: July 30, 1997.

Administrator.
