Small Community Options for Regulatory Equity Act of 2005 - Amends the Safe Drinking Water Act to require States exercising primary enforcement responsibility for public water systems to exempt any nonprofit small public water system (serving 10,000 or fewer persons) that so requests in accordance with this Act from the requirements of any national primary drinking water regulation for naturally occurring contaminants, including arsenic, radon, radium, uranium, and specified disinfection byproducts.
Requires exemption requests to include a finding that the system's compliance with applicable national primary drinking water regulations is not economically feasible. Precludes judicial or administrative review of such findings.
