Subject:

Calvert Cliffs Nuclear Power Plant NPDES Permit Renewal, State Discharge Permit No. 08-DP-0187, NPDES Permit MD0002399 Attached is the NPDES renewal application for the Calvert Cliffs Nuclear Power Plant (CCNPP) which is located in Lusby (Calvert County), MD. This application package consists of:

" EPA's Form 1 - General Information (and supporting documents) (Enclosure 1)

" EPA's Form 2C - Wastewater Discharge Information (and supporting documents)

(Enclosure 2)

" A copy of Exelon's Certificate of Workman's Compensation Insurance Coverage (Enclosure 3), and

" Wastewater Discharge Permit Application Supplement: Industrial Wastewater Treatment Plant Classification (Enclosure 4)

At our pre-application meeting with Maryland Department of the Environment (MDE) staff, the Department requested several other pieces of information to assist in the issuance of CCNPP's permit. Each of these items is briefly discussed below.

DMR Summary Statistics Attached to Form 2C are separate tables which present the previously reported DMR data and summary statistics for Outfall 001, and internal Monitoring Points 101A, 102A, 103A, 104A and 106A covering the three year period from January 2011 through December 2013. The summary statistics at the bottom of each table present applicable maximum, minimum or arithmetic average values based upon the monthly DMR data. Less than values (<) are shown as reported on the original DMRs, and used directly as the integer when used to calculate concentration means.

Form 2C Monitoring for Outfall 001 and MP101A As requested by MDE staff, effluent samples were collected for MP101A (the wastewater treatment plant internal monitoring point which discharges via Outfall 001) and analyzed for the

Mr. Richardson July 14, 2014 Page 2 Form 2C Part V-A and V-B analytes as part of this application monitoring program. Review of the data for Outfall 001, and MP 101A did not show any analytes that are problematic in comparison to applicable MDE criteria. These new data supplement the monthly DMR data which presents results for pH, TSS, Oil & Grease and discharge flows.

Consistent Effluent Quality As discussed during our pre-application meeting, Calvert Cliffs is a continuously operated baseload nuclear power plant with extraordinarily little variability in effluent quality. This is easily demonstrated by the attached DMR data (see Form 2C), as well as the fact that all of the combined internal waste streams make up less than 1 /1 0 0 th of one percent of the total discharge flow from Outfall 001 to the Chesapeake Bay (99.99 percent being non-contact cooling water from the Bay, discharged back to the Bay via Outfall 001).

Product Substitution Exelon Generation clearly recognizes the potential benefits of product substitutions to reduce discharge concentrations and loadings to the environment, and we strive to examine alternative products when they become available within the marketplace. The MDE recognizes, however, that nuclear power plants have very specific maintenance and operational requirements, and only rarely are product substitutions found that are compatible with the plant's systems and operational needs. As you know, Calvert Cliffs tried to eliminate the use of chlorine for biofouling control, conducted a substantial MDE-approved testing program to examine the effectiveness of a new product called Mexel. It was determined that Mexel was not effective and would contribute an increased total nitrogen load to the Chesapeake Bay. In summary, we will continue to investigate new environmentally friendly products that the nuclear industry determines to be safe and effective, and will work with MDE so that these products can be approved.

Update to CCNPP's Material Balance Study for Total Nitrogen and Total Phosphorus At our pre-application meeting, the Department requested that Exelon Generation update the material balance study that Calvert Cliffs developed and submitted to MDE as a requirement of Special Condition U ("Identification of Total Phosphorus and Total Nitrogen Sources at Calvert Cliffs Nuclear Power Plant"; Revised 31 August 2011), We are currently working to revise the previous material balance for nitrogen and phosphorus. The effort involves quantifying the annual loads of these compounds present in the necessary anti-corrosion and antiscaling products purchased and used on site, as well as the very small contribution expected from CCNPP's wastewater treatment plant.

Biofouling Control The control of biofouling organisms in CCNPP's non-contact cooling water system is critical to the operational efficiency of the plant, as well as the health and safety of workers who are required to work in confined spaces to keep the intake system clean. This continues to be an operational challenge. In attempts to reduce the use of chlorine for biofouling control, the facility has tried chlorine minimization, dechlorination, and most recently the use of Mexel. Given the clear need to control intake system biofouling, we request that CCNPP's revised permit include language that explicitly allows for special studies to be approved and implemented in a reasonably short period of time to determine effectiveness, environmental safety, and implementability.

Mr. Richardson July 14, 2014 Page 3 Cooling Water Intake Structures (CWQ Section 316b)

Exelon Generation has reviewed the pre-publication version of the Final Regulations to Establish Requirements for Cooling Water Intake Structures at Existing Facilities and Amend Requirements for Phase I Facilities, release by U.S. EPA in May 2014 which will become effective 60 days following publication in the Federal Register. Exelon Generation intends to perform the required studies and evaluations necessary to make the best-technology-available (BTA) determinations for reduction of impingement mortality and entrainment associated with CCNPP's cooling water intake structure. Consistent with the preamble to the Rule, because CCNPP is now in the process of NPDES permit renewal, the reports required under §122.21(r) would be submitted to MDE with the application for the next permit renewal cycle. We request that MDE provide Calvert Cliffs' staff as much notice as possible with regard to how this important regulation might be implemented for Maryland facilities.

Elimination of Outfall 005 Outfall 005 (swimming pool backwash) which was listed in the previous CCNPP permit no longer exists, and should not be included in the new permit.

Stormwater Dischar-ge Permitting Exelon Generation recognizes that MDE is moving towards the management of stormwater discharges from industrial facilities via the State's newly revised 12-SW General Permit. As we discussed, Exelon Generation plans to submit a complete Form 12-SW application within 6 months of the effective date of the newly issued NPDES permit. It is our understanding that Calvert Cliffs' stormwater discharges are currently permitted under our individual NPDES permit.

Should you have questions about CCNPP's discharges to surface waters, or the information presented in this NPDES permit application package, please contact Mr. Richard L. Szoch at 410-495-5210, or Mr. C. David Merryman at 410-495-4913.

EPA I.D. NUMBER (copy.from hem I ofForm 1) OUTFALL NUMBER MD0002399 001 CONTINUED FROM PAGE 3 OF FORM 2-C I PART C - If you are a primary industry and this outfall contains process. wastewater, refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for. Mark 'X" in column 2-a for all such GC/MS fractions that apply to your industry and for ALL toxic metals, cyanides, and total phenols. If you are not required to mark column 2-a (secondaryindustries,nonprocess wastewater ouffalls, and nonrequired GC/MS fractions), mark "X" in column 2-b for each pollutant you know or have reason to believe is present. Mark "X" in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant, you must provide the results of at least one analysis for that pollutant. If you mark column 2b for any pollutant, you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be discharged in concentrations of 10 ppb or greater. If you mark column 2b for acrolein, acrylonitrile, 2,4 dinitrophenol, or 2-methyl-4, 6 dinitrophenol, you must provide the results of at least one analysis for each of these pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater. Otherwise, for pollutants for which you mark column 2b, you must either submit at least one analysis or briefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part; please review each carefully. Complete one table (all 7 pages) for each outfall. See instructions for additional details and requirements.
