ntamination should also be included. Section 4.5.1.2 of the GEIS discusses this issue. It is possible that, for a given plant, no spills or incidents have occurred. In that case, reporting of soil and groundwater contamination in the ER would not be necessary. Information and Analysis Content If a plant has current or historical information regarding groundwater and soil contamination due to industrial practices, the ER should include the following information: • Provide a list of leaks, spills, or accidental releases including their nature, location, date, and amount spilled. Include the regulatory agency overseeing the incident and whether or not a noncompliance or notice of violation was issued. Also include a site map depicting the locations of the listed incidents. • Describe the cleanup or other mitigation completed for each of the listed source terms. • Provide a copy of the current NPDES permit issued under the Clean Water Act in an appendix to the ER. DG-4015, Page 31 Radionuclides Released to Groundwater Table B-1 states the following: Underground system leaks of process water have been discovered in recent years at several plants. Groundwater protection and monitoring programs have been established at all operating nuclear power plants. Specifically, 10 CFR 51.53(c)(3)(ii)(Q) requires the following: If the applicant’s plant has had known inadvertent releases of radioactive liquid into the groundwater, the applicant shall assess the radiological impact from the release(s). The applicant shall provide a radiological assessment in accordance with § 20.1501 which contains information on the source of the release, its location within the plant site, the known or estimated information on the involved radionuclides, quantities, forms, concentrations, and the projected impact to the environment (i.e., projected transport path and concentrations) during the license renewal term. A summary of existing reports describing the event(s) of any inadvertent
