REQUESTS FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE CALLAWAY PLANT, UNIT 1, LICENSE RENEWAL APPLICATION (TAC NOS.

ME7715 AND ME7716)

Dear Mr. Heflin:

By letter dated December 15, 2011, Union Electric Company, a subsidiary of Ameren Corporation and doing business as Ameren Missouri, submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54, to renew the operating license NPF-30 for Callaway Plant, Unit 1 for review by the U.S. Nuclear Regulatory Commission (NRC or the staff). The staff is reviewing the information contained in the license renewal application and has identified, in the enclosure, areas where additional information is needed to complete the review.

These requests for additional information were discussed with Ms. Sarah Kovaleski, and a mutually agreeable date for the response is within 30 days from the date of this letter. A draft document containing these requests was also sent to Sarah Kovaleski on July 3, 2012. If you have any questions, please contact me at 301-415-6337 or bye-mail at Carmen.Fells@nrc.gov.

Sincerely, Carmen Fells, Environmental Project Manager Reactor Projects Branch 2 Division of License Renewal Office of Nuclear Reactor Regulation Docket No. 50-483

Request for Additional Information For Callaway Plant, Unit 1, License Renewal Environmental Review Aquatic Ecology

1. Provide a copy of the review of new and significant information document or describe what specific records or information Ameren Missouri (Ameren) reviewed to determine that no new and significant information exists for each of the aquatic ecology Category 1 issues applicable to Callaway Plant, Unit 1 (Callaway).

2. Clarify the location of the discharge point for blow-down water and other waste streams to the Missouri River.

3. Provide copies of or, if copies are not available, descriptions of pre-operational surveys of fish conducted in 2007 and 2008 within reach of the Missouri River adjacent to Callaway's cooling water intake mentioned on page 20, plus any associated reports or documentation.

4. Provide any associated reports or documentation related to the historical records and contacts with State and Federal resource agencies related to the occurrence of State and Federally listed threatened and endangered species.

5. Provide a description of the cooling water intake system, including the intake velocity at the traveling screens, design and operation of the traveling screens, and any other operational procedures or structural designs that affect impingement and entrainment at the Callaway Pump Station on the Missouri River. Also provide information regarding the depth of the intake and the means by which flow is regulated for the flow intake structure.

6. Provide a description of the fish escape openings at the water intake structure and an explanation of why a fish return system is not required. Also provide copies of any studies or documentation of the effectiveness of this mitigation system.

7. Provide a description of what chemicals are used and the associated application rates and schedules to treat the cooling and auxiliary water system.

8. Provide for review the available studies or procedures that Ameren funds, undertakes, or uses to document that protected species are not impinged or entrained at the intake or affected by the thermal effluent. These species should include the fish species that the protected freshwater mussels attach to during their glochidal stages.

9. Provide the Union Electric Company 1986 report "Evaluation of Cooling Water Intake Impacts on the Missouri River," and any other similar reports referencing effects on aquatic resources.

10. Provide a description of the thermal discharge temperatures of the blowdown water.

ENCLOSURE

- 2 Environmental Justice & Socioeconomics

1. Provide information about any observed subsistence consumption behavior patterns, specifically fish and wildlife consumption, by minority and low-income populations in the vicinity of Callaway. This subsistence consumption behavior could consist of hunting, fishing, and trapping of game animals and any other general food gathering activities (e.g., collecting nuts, berries, and other plant materials) conducted by minority and low income individuals.

2. In addition to property tax payment information presented in Section 2.10 of the environmental report (ER), describe any other major annual support payments, one-time payments, and other forms of non-tax compensation (if any) provided to local organizations, communities, and jurisdictions (e.g., county, municipality townships, villages, incorporated places, and school districts) on behalf of Callaway.

3. Provide data on the height of the tallest (visible from offsite locations) structures at Callaway and general information on the visibility of plant facilities from various offsite locations.

Electromagnetic Fields

1. For the computer code used to calculate the induced current, provide details of the code, the model developed for this plant, the input, and the output results.

Hydrology and Water Quality - Groundwater

1. Provide the plant flow diagram that was part of the recent National Pollutant Discharge Elimination System (NPDES) permit renewal.

2. Confirm and provide documentation that the groundwater sample reported in the ER (Table 2.3-2) was analyzed for strontium, rather than only for the isotope of strontium (strontium-90).

3. For those wells with tritium levels above background provide data that shows changes in tritium concentrations in groundwater over time.

4. To adequately describe groundwater quantity impacts, NRC needs to know the source or sources of the water that flows into the groundwater sump (Le., What aquifers are being impacted or are there other sources for the water?). In responding to this request, explain why you believe the groundwater is being supplied from that source or sources that are identified in the response. If there are other sumps in the basements of the buildings of the power block collecting groundwater, estimate the rate of groundwater collected from those sources. Provide cross section drawings

- 3 referred to in an October 8, 2008, letter from Ameren to the Missouri Department of Natural Resources (MDNR) (ML083150703) as Attachment F.

5. Provide a map showing the closest private well to Callaway that is approximately 0.25 miles southeast of Intake Well #1.

Hydrology and Water Quality - Surface Water

1. Provide a description of settling and effluent discharge pond changes (i.e., new ponds needed and old ponds abandoned) over the period of license renewal.

2. Provide any notices of violation (NOVs), nonconformance notifications, or related infractions received from regulatory agencies associated with NPDES permitted discharges, sewage systems, groundwater or soil contamination, including spills, leaks, and other inadvertent releases of fuel solvents, chemicals, or radionuclides (covering the past 5 years).

Land Use and Transmission Lines

3. Provide a summary of Callaway greenhouse gas emissions. Include emissions of carbon dioxide from permitted combustion sources and emissions of sulfur hexafluoride (SFs) leakage, if available.

4. Provide noise emissions studies conducted at Callaway, if any, and any information about noise that could be considered a nuisance to offsite property owners. Also, provide information about any noise complaints.

Terrestrial Ecology

1. Provide a copy of the review of new and sig nificant information document or describe what specific records or information Ameren reviewed to determine that no new and

- 2 significant information exists for each of the terrestrial ecology Category 1 issues applicable to Callaway.
