-Radiological environmental monitoring program (REMP) - a small sample of monitoring stations (e.g., air monitoring stations, thermoluminescence dosimeter (TLD) stations, drinking water, milk, and vegetation, including monitoring stations co-located with State monitoring stations).
Land Use and Visual Resources LU-1 The ER (Section 3.2, p. 3-5 and 3-6) states that the LSCS site is 1,568 Grange hectares (ha; 3,875 acres (ac)) in size. Of that area, the cooling pond occupies 833 ha (2,058 ac); industrial or developed areas account for 60 ha (150 ac); undeveloped areas account for 101 ha (250 ac); and the LaSalle Fish Hatchery occupies 18 ha (45 ac). Describe the land use(s) for the remaining 556 ha (1,372) ac.
LU-2 The NRCs supplemental environmental impact statement (SEIS) for Grange LSCS license renewal will include a description of fuel at the LSCS site that mirrors Section 3.1.6.2 in the NRCs 2013 GEIS (ML13107A023).
To facilitate the staffs preparation of this section, provide the following information:
- a. How much nuclear fuel does each LSCS unit contain in pounds or metric tons? The approximate or average weight is sufficient.
- b. On average, what percentage of reactor fuel does Exelon replace during each outage?
- c. Describe the use and storage capacity of all onsite fuel storage tanks, including diesel, gasoline, and natural gas.

Page 6 of 13
LASALLE ENVIRONMENTAL AUDIT NEEDS LIST LU-5 Regarding the transmission lines and onsite switchyard, please Grange provide the following information.
- a. Who owns and operates the onsite switchyards?
- b. The Final Environmental Statement for Operation of LSCS (FES-O; ML14353A388) states that of the four 345-kV lines that connect to the onsite switchyard, two lines connect to the Plano substation and two lines connect to the East Frankfort substation. However, the ER (Section 2.2.6, p. 2-13) states that two lines connect to Braidwood Station, and the East Frankfort substation is not mentioned. Please clarify these seemingly contradictory descriptions.
- c. The FES-O describes the 138-kilovolt line connections to Mazon, Illinois and Streator, Illinois as temporary. Do these lines remain active?
- d. While the NRC staff understands that Exelon considers the transmission lines connected to the LSCS switchyard to not be in-scope for license renewal (as stated in Section 2.2.6, p. 2-13 of the ER), the staff assumes that ties exist that connect the turbine buildings to the switchyard and that these ties would be in-scope for license renewal. Please describe any transmission lines that connect the nuclear power plant to the substation where electricity is fed into the regional power distribution system. Please also describe any transmission lines that supply power to the nuclear plant from the grid in accordance with Footnote 4 of Table B-1 of 10 CFR Part 51, Subpart A.
LU-6 Clarify whether the ERs offsite land use information (Section 3.2, p.3- Grange
- 5) is based on the 2006 or the 2011 Multi-Resolution Land Characteristics Consortium (MRLC) National Land Cover Database. If this section is based on 2006 data, provide any applicable updates to the section resulting from the 2011 data.
Meteorology, Air Quality and Noise M&A-1 Provide the following meteorological information from the data Martinez recorded at LSCS meteorological facility. The meteorological data should include the most recent 5 years for which data is available.
- a. mean monthly and annual temperatures;
- b. mean monthly precipitation and annual precipitation; and
- c. Provide seasonal and annual summary wind statistics in the form of wind direction, wind roses, annual average wind speed and peak wind gust.
M&A-2 The ER identifies that LSCS is subject to the emission standards for Martinez hazardous air pollutants for reciprocating internal combustion engines, 40 CFR Part 63, Subpart ZZZZ. Please clarify if the gasoline dispensing facility and fuel storage tank are subject to National Emission Standards for Hazardous Air Pollutants: Gasoline Dispensing Facilities (40 CFR 63, Subpart CCCCC). If available, please provide annual hazardous air pollutants (HAP) emissions from LSCS permitted emission sources.
M&A-3 Provide supporting calculations (e.g., operating hours per year, fuel Martinez consumption and rates, etc. as applicable for each source) for the greenhouse gas (GHG) emissions presented in Table 3.3-2 of the ER.
Page 7 of 13
LASALLE ENVIRONMENTAL AUDIT NEEDS LIST M&A-4 Are there expected upgrade/replacement activities for Martinez equipment/operation that could increase or decrease air emissions over the license renewal period?
M&A-5 Describe the compliance history associated with LSCS Federally Martinez Enforceable State Operating Permit (FESOP) permit No. 75040086.
Provide the five most recent annual emission reports submitted to the IEPA associated with LSCS FESOP permit No. 75040086. Has LSCS received any Notice of Violations (NOVs) from the Illinois Environmental Protection Agency (IEPA) regarding the FESOP? If so, provide copies of such NOVs.
M&A-6 Provide a copy of the FESOP permit renewal application dated July Martinez 15, 2005, referenced in the ER. Has Exelon received any correspondence from the IEPA regarding the FESOP permit renewal application? If so, please provide copies of such correspondence.
M&A-7 Section 4.2 of the ER states that [a]ir quality effects of transmission Martinez lines were not evaluated because, as is explained in Section 2.2.6 of the ER, no LSCS transmission lines are within the scope of the LSCS license renewal environmental review. Section 2.2.6 of the ER discusses that the offsite transmission lines are not in scope in accordance with footnote 4 of Table B-1. However, Section 2.2.6 does not identify the in-scope transmission lines, which as defined in footnote 4 of Table B-1 are transmission lines that connect the nuclear power plant to the substation where electricity is fed into the regional power distribution. Section 2.2.6 of the ER identifies electrical connections between the main plant and the LSCS switchyard. Therefore, the Category 1 issue, Air Quality effects of transmission lines is applicable to LSCS. Provide an evaluation of any new and significant information that pertains to the Category 1 issue, Air Quality effects of transmission lines for those in-scope transmission lines that connect the nuclear power plant to the on-site LSCS switchyard.
M&A-8 Provide the following ER reference: (IEPA 2000) Illinois Martinez Environmental Protection Agency. 2000. Federally Enforceable State Operating Permit for LaSalle County Generating Station No.
75040086. December 11, 2000.
M&A-9 The ER provided GHG emission inventory for the year 2013. Does Martinez Exelon have a GHG inventory for prior years? If so, please provide this information for the most recent 5 years.
M&A- Describe the LSCS off-site noise environment and primary noise Martinez 10 sources in the vicinity of LSCS.
M&A- The ER states that Illinois does not have regulations or guidelines for Martinez 11 environmental noise. However, Illinois has a noise regulation with allowable octave band sound levels according to emitting and receiving land-use classification and time of day (IAC, Title 35:
Environmental Protection, Subtitle H: Noise). Please clarify if LSCS is subject to Illinois noise regulation and if LSCS is in accordance with these regulations.
