ATTACHMENT (1)
RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION; APPLICANT'S ENVIRONMENTAL REPORT - OPERATING LICENSE RENEWAL STAGE NRC Ouestion No.17 Chapter 2 of the Baltimore Gas and Electric Company (BGE) [ License Renewal ApplicationJ Environmental Report (ER) focuses on coal and gas as the feasible generating alternatives. Imported power is briefly discussed on page 2-15 of the ER as a feasible alternative. However, BGE noted that imported power would be generated by one of the technologies discussed in Chapter 8 of the Generic Environmental Impact Statement (GEIS) and adopted by reference the GEIS Chapter 8 description of other technologies that would likely generate imported power. Provide any additional information that may supplement or update imported power information specifically for Calvert Cliffs with regard to what percentage of electrical sales would be purchased power and the likely sources of generation. This information may have been generated by other entities such as the State of Maryland or the Public Service Commission.
BGE Response Baltimore Gas and Electric Company is not aware of any additional information that may supplement or update the discussion ofimported power on page 2-15 of the ER. Recent generating additions in the competitive electric market have been primarily either simple cycle combustion turbines or l
combined cycle facilities with a lesser amount of coal-fired plants, BGE has stated and still believes that future generation additions will be predominantly satisfied by those technologies. With the evolution of regional and national bulk power markets, the movement of electric energy between regions is expected to grow. There is a high probability that the importation of energy from Canada will continue. From a historical perspective, it has been BGE's experience that replacement energy l
for Calvert Cliffs Nuclear Power Plant (CCNPP) is predominantly provided by interchange purchases from the Pennsylvania-New Jersey-Maryland Interconnection, unless a specific bilateral contract has been effected.
l NRC Ouestion No.18 The ER lists BGE conservation program components, including peak clipping programs, load shifting programs, and conservation programs (page 2-18). If these programs have changed since the ER assessment was performed or plan to be changed, identify the changes and provide an update of the assessment of BGE's load management programs.
BGE Resnonse l
Each of the conservation progiam components identified on page 2-18 of the ER still exist in BGE's load management programs. However, the emerging competitive electricity market along with l
pending retail choice for customers has significantly reduced our long-term growth expectations for l
most programs. Baltimore Gas and Electric Company's 1998 Integrated Resource Plan (IRP) response to the Maryland Public Service Commission indicated an existing total of about 730 l
megawatts (MWs) in 1997; whereas the existing value for 1996 reported in the ER was "about 700 MWs." The current expectation for the future indicates a value of approximately 750 MWs in 2012; whereas the ER reported a value of"about 1,000 MWs in 2016."
NRC Ouestion No.19 The BGE ER states that the demand-side management program produces an annual peak demand generation reduction of about 700 MWs, and that it can continue to increase generation savings from demand-side management to about 1,000 MWs in 2016 (Page 2-18). Provide a discussion (quantitative, 1
ATTACHMENT (1)
RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION; APPLICANT'S ENVIRONMENTAL REPORT - OPERATING LICENSE RENEWAL STAGE if possible) to support this number and the conclusion that demand-side management is not a feasible alternative to CCNPP license renewal.
BGE Response At the time the ER was prepared, BGE's 19971RP indicated actual valm for 1996 of 211 MWs for conservation programs,121 MWs of interruptible load, and 357 MWs of direct load control, for a combined total of 693 MWs (i.e., about 700 MWs). The 19981RP now indicates actual values for 1997 of 238 MWs for conservation programs,132 MWs of interruptible load, and 359 MWs of direct load control, for a combined total of 729 MWs (i.e., about 730 MWs). The future expectation at the time of the ER showed 382 MWs for conservation programs,185 MWs of interruptible load, and 428 MWs of direct load control, for a combined total of 995 MWs (i.e., about 1,000 MWs). The current future expectation is showing 272 MWs for conservation programs,164 MWs ofinterruptible load, and 319 MWs of direct load control, for a combined total of 755 MWs (i.e., about 750 MWs).
Baltimore Gas and Electric Company previously concluded that, "Because the demand-side
)
management savings are part of the long-range plan for meeting projected demand, it is not available as an ' offset' for CCNPP license renewal." This conclusion remains unchanged and is further reinforced by diminishing long-term expectations for load management.
NRC Ouestion No. 20 With respect to the option of delaying retirement for power plants in BGE's system (page 2-18), provide j
the current BGE generating unit retirement plans. Also, provide a discussion supporting the statement, "Without retiring any generating units, BGE will require additional capacity in 2000 or 2001. For this reason, BGE has determined that delayed retirement of other BGE generating units would not be a feasible alternative to CCNPP license renewal."
BGE Response In the current Stranded Cost Filing with the Maryland Public Service Commission, BGE used the 1992 Technical Update of Depreciation Rates for Baltimore Gas and Electric Company for the
\\
purpose of modeling retirement in this study. This retirement schedule is presented in the following tabulation:

Wagner 4 410 2015 Total 1,391 Using a reserve obligation of 15% and based on information from the 1998 BGE IRP, BGE will have a Pennsylvania-New Jersey-Maryland reserve obligation of 6,759 MWs (5,877 x 1.15) in the year 2000. With a current supply portfolio projected to be 6,562 MWs, BGE is expecting to be deficient l
.by nearly 200 MWs in the year 2000. During the assessment of capacity requirements for the ER, BGE did not incorporate any retirement plans. Therefore, delayed retirement of other BGE generating units would not be a feasible alternative to CCNPP license renewal.
NRC Ouestion No. 21 Provide a simplified plant water flow schematic to assist in understanding the relationships between l
inflows, water processing, plant-related impacts to water, and the associated outfalls. This information l
will be summarized in Chapter 2 of the Supplemental Environmental Impact Statement as background text on Water Use and Water Quality Issues. The figure should include average flow rates on flow paths.
' Inflows'should include the multiple wells used for plant water (not the non-plant wells, such as at the firing range and Camp Canoy).
BGE Response Attachment (3) provides the water flow schematic for CCNPP Units I and 2. Well water usage was determined by averaging the withdrawal data over the 12-month period from September 1,1997 through August 31,1998. All other flow data are based on averages of readings taken from various plant flow meters during three months within the past year (October 1997, February 1998, and July 1998). It was noted that the average discharge flow from the three plant wells (409,000 gallons per day [gpd)) does not equal the average values indicated for the various plant processes. The differences are believed to be the result of several factors, including: (1) the sampling period for intakes (well water discharges) is different than that for usage and discharge; (2) flow is not measured in some plant process applications (e.g., plant service water process applications); and (3) different methods are used, due to measuring equipment availability, to measure system flow rates. Accuracy of these different methods vary, which introduces an overall water balance inaccuracy.
j NRC Ouestion No. 22 Provide the monthly average groundwater withdrawals for the past 5 years to allow an adequate understanding of the seasonal variability of groundwater usage. Alternatively, if annual average flows are available and provided instead of monthly flows, explain how use of these flows for drawdown calculations ensure that transient drawdowns at a sub-annual time scale would not result in a significantly greater predicted impact.

RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION; APPLICANT'S ENVIRONMENTAL REPORT - OPERATING LICENSE RENEWAL STAGE BGE Response A tabulation of the monthly groundwater withdrawals, from January 1993 through June 1998, is provided in Attachment (4). This information is derived from the Semi-Annual Groundwater t
Withdrawal Reports submitted by BGE to the State of Maryland, with the exception of the data provided from July 1993 through December 1994. During this period, the groundwater usage was l
miscalculated as a resu!t of a newly-installed flow meter. These discrepancies were subsequently identified to the Stat fr Reference (1). To account for the correction of these discrepancies, the j
groundwater withdrawals in Reference (2), Table 2-4 are revised, as indicated in Attachment (2),
" Errata to Applicant's Environmental Report - Operating License Renewal Stage."
NRC Ouestion No.1 Provide the current / Clean Water Act SectionsJ 316(ay316(b) permit documentation. During the site tour, BGE staff stated a comprehensive report that summarizes all impingement studies related to the plant was being developed and could be provided to the NRC. Please provide a copy of this report for background purposes or a schedule when it will be available.
BGE Response Attachment (5) provides the current National Pollutant Discharge Elimination System (NPDES) l permit, NPDES Permit Number MD0002399, for CCNPP, effective June 16,1994 through June 15, 1999.
1 The comprehensive report summarizing the impingement studies related to CCNPP between 1975 and 1995 will be provided under separate cover no later than December 6,1998 as Attachment (6).
l NRC Ouestion No. 24 i
During the site visit, CCNPP staff identified several biocides that have been or will be used. Provide a current listing and description of biocides that are planned or are likely to be used during the renewal period.
)
i BGE Response In the GEIS (Reference 3), the NRC concluded that water quality effects of discharge of chlorine and other biocides are considered to be of small significance for all plants. Based on this conclusion, the potential chemical effects resulting from discharges of chlorine or other biocides was classified as a Category 1 Issue. Although this question addresses a Category 1 Issue, which was beyond the scope of the environmental report required by 10 CFR 51.53(c)(3)(ii), the requested information is provided below.
The biocide currently used at CCNPP is a sodium bromide and sodium dichloro-s-triazinetrione compound distributed by the Calgon Corporation under the trade name Towerbrom 960 This biocide was approved for use in the Saltwater System by Maryland Department of the Environment (MDE) in January 1998 (Reference 4). Currently, no other biocides are used in any water systems at CCNPP. Baltimore Gas and Electric Company currently has no plans to use any biocides other than Towerbrom; however, should these plans change, BGE will follow the approval process outlined by MDE in CCNPP's NPDES Permit prior to use.

RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION; APPLICANT'S ENVIRONMENTAL REPORT - OPERATING LICENSE RENEWAL STAGE NRC Ouestion No. 25 Under the Endangered Species Act compliance requirement, BGE had initiated informal consultations with the National Marine Fisheries Service and the U.S. Fish and Wildlife Service (USFWS), and a written reply from National Marine Fisheries Service was included in the ER. Provide a copy of the response after it is received from the USFWS or a schedule when it will be available, if possible.
BGE Response A copy of the USFWS response to BGE's informal consultation request is provided as Attachment (7)
(Reference 5).
NRC Ouestion No. 26 Depth measurements of the intake channel taken by the State of Maryland during the site visit indicated an increase in the level of siltation since the channel was constructed. Clarify BGE's intentions with respect to dredging the channel either as part of refurbishment activities or a renewed license. The information should include timing, permits, monitoring requirements, disposal of the dredged material, etc.,if available.
BGE Response The intake channel was constructed to draw the cooler water from the deeper areas of the bay. There is no data to support whether the lower temperatures were actually achieved, nor is there any long-term temperature data available to allow correlation of the temperature stratification to the silt build-up in the channel. Based on the lack of data available to justify a major dredging project, BGE currently has no plans to dredge the channel either as a part of refurbishment activity or a renewed license. Should conditions change such that maintenance dredging of the channel is required (e.g.,
following a major hurricane), an application for a dredging permit, including the environmental review of the methods of redredging and spoil disposal, will be submitted to the applicable licensing and permitting agencies at that time.
NRC Ouestion No. 27 He power line rights-of-way cross at least one sensitive habitat. Provide a map of the power line showing the locations of the following types of sensitive habitats (if releasable):
(a) Wildlife sanctuaries, refuges, or preserves; (b) Habitats identified by State or Federal agencies as unique, rare, or of priority for protection; (c) Wetlands, floodplains, or other resources specifically protected by Federal regulations, Executive Orders, or by State regulations; and (d) Land areas identified as " critical habitat" for species listed as threatened or endangered by the U.S. Fish and Wildlife Service.

(a) There are no wildlife sanctuaries, refuges, or preserves on the power line rights-of-way for l
(b) The Maryland General Assembly has designated a geographical area around the tidal shoreline of the Chesapeake Bay. The critical area extends 1,000 feet landward from the mean high tide line or from the boundary of adjacent tidal wetlands. The CCNPP power line right-of-way approaches the Chesapeake Bay Critical Area at one location, between Tower No.1544 and Tower No.1546. The location of this area is shown in Attachment (8), on Figure 4 (Map No. 46-3) at coordinates 4E-SE,53S.
(c) As discussed in Reference (3), Section 2.1.5, a single right-of-way was originally constructed from CCNPP to the Waugh Chapel Substation in Anne Arundel County, Maryland. This right-of-way is approximately 47 miles in length, and includes two separate three-phase 506-kV transmission lines. In 1994, BGE completed a new 500-kV line, referred to as the South Circuit. The 18-mile South Circuit parallels the Waugh Chapel lines from CCNPP north i
approximately nine miles before diverging in a northwesterly direction to connect with a line at the Potomac Electric Power Company Chalk Point generating station.
Prior to construction of the South Circuit right-of-way, BGE submitted a wetlands delineation report to MDE, Reference (6). The wetlands delineation report provides a description of the wetlands areas within the South Circuit transmission corridor, including the portion of the South Circuit that runs parallel to the Waugh Chapel lines. Attachment (8), Table (1) provides a listing of the 45 South Circuit wetlands areas, including the drainage basin for each area.
Attachment (8), Figure (1) is a copy of figure from the wetlands delineation report showing the l
location of each wetland area along the South Circuit transmission line.
l Attachment (8), Table (2) provides a listing of the wetlands, road screens, and other protected l
resources along CCNPP's Waugh Chapel transmission corridor, including the portion of the corridor that runs parallel to the South Circuit transmission lines. The Waugh Chapel transmission corridor is shown on Figures (2) through (13). The location of the protected resources may be approximated by using the map coordinates indicated on Table (2). Screens are vegetated buffer zones located on either side of a roadway in areas where a transmission line traverses the roadway. Baltimore Gas and Electric Company is required to maintain these screens in concurrence with the DNR roadside tree laws. Table (2) also identifies the transmission corridor wetlands, and delineates those wetlands that are associated with a stream.
(d) The power line rights-of-way for CCNPP do not traverse any designated " critical habitats," as defined in Section 7 of the Endangered Species Act.
NRC Out31 ion No. 28 Page 2-6 of the ER provided CCNPP workforce numbers. During the site visit, updated numbers were identified. Te more fully review traffic and water issues in the southern part of Calvert County and the eastern part of St. Mary's County, provide a current residence count of CCNPP employees by county, including counties outside the Tri-County area, if available.
BGE Response Based on a review of corporate employment records, Calvert Cliffs' current workforce consists of approximately 1,310 BGE employees (October 1998) and approximately 240 contractors.

BGE Response Baltimore Gas and Electric Company currently has no plans for modifying the radioactive waste or effluent control systems for license renewal. Minor changes may be made to the these systems as a result of maintenance activities, equipment obsolescence, and general equipment upgrades. Future modifications to the radioactive waste management systems or effluent control systems will conform to the existing regulatory limits. In accordance with 10 CFR 50.59, any proposed changes that would involve an unreviewed safety question will be submitted to the NRC for approval prior to implementation.
NRC Ouestion No. 30 Provide a brief description of the transportation of radioactive materials offsite. Discuss the types of radioactive materials shipped, the typical number of shipments per year, and any expected increases in shipment during the renewal period. This information will be summarized in the Supplemental Environmental Impact Statement as background and descriptive text.
BGE Response Radioactive materials are periodically shipped to and from CCNPP in accordance with the Federal regulations governing transportation, shipment, and burial (10 CFR 20,61, and 71 and 49 CFR 172 through 178). Approximately 150 shipments are made from CCNPP each year, consisting of reusable 7

Only 20 of these are to a waste burial site or volume reduction processor. The volume of radioactively contaminated waste generated varies from year to year, but typically remains below 7500 cubic feet per year. Aggressive volume reduction and minimization programs are expected to further reduce the annual volume.
NRC Ouestion No. 31 Clarify the following items:
(a) Under the topic " Groundwater Use," on page 2-3, the quantities of the permitted withdrawal rate as stated within first and last paragraphs are inconsistent. Correct this discrepancy to indicate the current state permit withdrawal rate.
i (b) In Appendix H, page H-7, there is a reference to Table 1 that is not attached. Does this refer to Table 1-1 on page 1-17 If not, supply the appropriate table.
BGE Response (a) The current permitted withdrawal rate is a daily average of 450,000 gpd on a yearly basis, as indicated in the last paragraph of Section 2.1.4, Groundwater Use. This is consistent with information provided graphically in Environmental Report Figure 2-8, CCNPP groundwater withdrawals.
The second sentence of the first paragraph in Section 2.1.4 should read,
" Subsequent State permits have reduced this limit to a daily average of 450,000 gpd on a yearly
)
basis." The revised text is provided in Attachment (2), " Errata to Applicant's Environmental Report - Operating License Renewal Stage."
(b) The table that was referenced in Appendix H, Findings, Item 3, was a listing of Federal, State, local, and regiona' licenses, permits, consultations, and other approvals pertintent to current CCNPP station operation. This table was included in the Coastal Zone Management Program Consistency Certification submitted to the MDE Water Management Administration, but was inadvertently omitted from the Coastal Zone Management Program Consistency Certification in Appendix H of CCNPP's Environmental Report - Operating License Renewal Stage. A copy of this table is included in Attachment (2), " Errata to Applicant's Environmental Report - Operating License Renewal Stage."
