5000 Dominion Boulevard, Glen Allen, VA 23060 @ lniOw Web Address: www.dom.com May 10, 2011 Susan Mackert Northern Regional Office 13901 Crown Court Woodbridge, VA 22193 Re: Sampling / Testing Plan and Requests for Waivers Reissuance of VPDES Permit No. VA0052451 Dominion - North Anna Power Station

Dear Ms. Mackert:

Dominion is preparing the application for reissuance of the VPDES permit for the North Anna Power Station. The current permit expires on October 24, 2012. In accordance with the requirements as we understand them, we are developing a sampling plan to include the upcoming work planned for this facility. We request the following sampling and testing waivers associated with the VPDES permit reissuance application:

I. The sample results from Outfall 001 adequately characterize the effluent discharged into state waters. Accordingly, we request that testing requirements for internal outfalls 103, 104, 105, 107, 108, 109," 110, 112, 113, 114 and 115 be limited to the parameters monitored in the effective VPDES permit and all other monitoring requirements, including the 24-hour composite sample requirement, be waived.

2. For Outfalls 013 and 020, we request that the requirement for 24-hour composite samples be waived and grab samples be allowed. Effluent quality is not expected to vary greatly during a 24-hour period, and thus grab samples are adequately sufficient to characterize the effluent.

3. Dominion requests that testing requirements for delisted priority pollutants (e.g.

trichlorofluoromethane, bis (chloromethyl) ether, and dichlorodifluoromethane) be waived for all sampled outfalls.

4. For all stormwater samples, we request that the requirement for flow-weighted composite samples be waived and only grab samples be taken. Historic data suggest little difference between the grab sample and composite sample results, with the grab sample results being equal to or greater than the composite sample results approximately 75% of the time (141 of 180 observations) thus suggesting that grab samples provide a more conservative characterization of the discharge (see the enclosed stormwater data from the 2007 permit reissuance application). Additionally, for comparison purposes, Dominion would like to provide stormwater data for all outfalls based on one storm event; pulling both grab samples

and flow-weighted composite samples for six outfalls makes this'task difficult. Given these considerations, the stormwater quality is most conservatively characterized by grab samples.

5. For all sampled outfalls (except Outfall 111), we request a sampling waiver for fecal coliform as no station industrial activities contribute to this parameter.

6. With respect to sampling for the Water Quality Standards parameters, we request sampling and analysis relief for tributyltin (TBT). This parameter is believed to be absent from the discharges as the facility does not employ this parameter onsite nor does it perform any ship maintenance activities.

Aside from the waivers requested, all application sample testing will be conducted in accordance with all applicable requirements.

The submission of EPA Form 2A for internal sewage treatment plant outfalls (e.g. outfall 111) is not a specified regulatory requirement; however, Dominion intends to submit this form in support of the permitting of these internal outfalls. Accordingly, we propose to complete item A. 12 for internal outfall 111 utilizing existing DMR data (generated from January 2008 -

December:2010) and perform a minimum of one sample analysis for any remaining parameters.

All samples for this outfall will be grab samples.

Dominion requests that representative sampling be allowed for identical outfalls. Specifically, we request that intake samples be representative of Outfall 016. Discharges from Outfall 016 consist of intake screen wash water where no additional chemicals are added to the intake water (i.e. pure lake water). Similarly, Outfall 021 is substantially identical to Outfall 020; as Outfall 021 is permitted for emergency situations and has never been used, we request that Outfall 020 samples be representative of Outfall 021. Outfall 013 serves as an alternative discharge route for internal Outfall 104. We request that effluent data from Outfall 104 may be used for Outfall 013 in the event that a discharge from Outfall 013 is not available.

A sample plan summary is also included with this correspondence.

Dominion appreciates this opportunity to review these requirements and coordinate our sampling plan with your agency. If you have any questions, please contact Gina Kelly 804/273-3174 or Ken Roller at 804/273-3494.

Sincerely, Services

,13901 Crown Court Woodbridge, VA 22193 Re: Addendum to the Sampling / Testing Plan and Requests for Waivers Reissuance of VPDES Permit No. VA0052451 Dominion - North Anna Power Station

Dear Ms. Mackert:

Upon review, an omission was noted in our original sampling plan and waiver request letter submitted to DEQ on May 10, 2011. Specifically, we request that testing requirements for internal outfall 101 be limited to the parameters monitored in the effective VPDES permit (i.e. flow and temperature) and all other monitoring requirements, including the 24-hour composite sample requirement, be waived. This internal outfall discharges condenser cooling water where the only parameter of concern is temperature.

Also, the sample results from Outfall 001 adequately characterize the effluent discharged into state waters, including contributions from this source of wastewater.

Dominion appreciates this opportunity to review these requirements and coordinate our sampling plan with your agency. If you have any questions, please contact Gina Kelly 804/273-3174 or Ken Roller at 804/273-3494.

Taylor Director, Electric Environmental Services Dominion Virginia Power 5000 Dominion Boulevard Glen Allen, VA 23060 Re: Dominion - North Anna Power Station, VPDES Permit No. VA0052451

Dear Ms. Taylor:

Thank you for your correspondence dated May 10, 2011, and June 24, 2011, regarding sampling and testing waivers associated with the referenced VPDES permit reissuance application. Staff has reviewed Dominion's sampling and testing waiver request and has the following comments.

Waiver Request Sample results from Outfall 001 adequately characterize the effluent discharged into State waters. Accordingly, Dominion requests that testing requirements for internal Outfalls 101, 103, 104, 105, 107, 108, 109, 110, 112, 113, 114, and 115 be limited to the parameters monitored in the effective VPDES permit and all other monitoring requirements, including the 24-hour composite sampling requirement, be waived.

Staff Response Staffhas no objection to limiting the parameters monitored for internal Outfalls 101, 103, 104, 105, 107, 108, 109, 110, 112, 113, 114, and 115 to those parameters monitored in the effective VPDES permit. The discharge from internal Outfalls 103, 104, 105, 109, 110, 112, and 113 is addressed under Federal Effluent Guidelines established in 40 CFR Part 423 - Steam Electric Power Generating Point Source Category. Monitoring requirements established under this Federal Effluent Guideline are reflected in the effective VPDES permit for these internal outfalls. As such, all monitoring requirements except for those parameters monitored in the effective VPDES permit are waived.

Dominion correspondence states that Outfall 013 serves as an alternate discharge route for internal Outfall 104 and requests that effluent data from Outfall 104 be used for Outfall 013 in the event that a discharge from Outfall 013 is not available. Because Outfall 013 is a direct discharge to Lake Anna, staff objects to monitoring internal Outfall 104 for only those parameters in the effective VPDES permit. As such, Dominion shall monitor internal Outfall 104 in accordance with the requirements of EPA Form 2C.

Staffhas no objection to the use of grab sampling in lieu of 24-hour composite sampling for internal Outfalls 101, 103, 104, 105, 107, 108, 109, 110, 112, 113, 114, and 115. As such, the 24-hour composite sampling requirement is waived.

VA0052451 Response to Waiver Request Page 2 of 3 Waiver Request Dominion requests that the requirement for 24-hour composite sampling be waived for Outfalls 013 and 020.

Staff Response Staff has no objection to the use of grab sampling in lieu of 24-hour composite sampling for Outfalls 013 and 020. As such, the 24-hour composite sampling requirement is waived for Outfalls 013 and 020.

Waiver Request Dominion requests that testing requirements for delisted priority pollutants consisting of Bis(Chloromethyl)Ether, Trichlorofluoromethane, and Dichlorodifluoromethane be waived for all sampled outfalls.

Staff Response In accordance with Guidance Memo 10-2003, sampling and reporting for the delisted priority pollutants consisting of Bis(Chloromethyl)Ether, Trichlorofluoromethane, and Dichlorodifluoromethane is not required. As such, the sampling requirement for these three parameters is waived for all sampled outfalls.

Waiver Request Dominion requests for all storm water samples that the requirement for flow-weighted composite samples be waived and only grab samples be taken.

Staff Response Staff has no objection to the use of grab sampling in lieu of flow-weighted composite samples for storm water outfalls. As such, the flow-weighted composite sampling requirement is waived for storm water outfalls.

Waiver Request Dominion requests that for all sampled outfalls (with the exception of Outfall 111), fecal coliform sampling be waived.

Staff Response The discharge from all outfalls, with the exception of Outfall 111, is considered industrial in nature. Fecal coliform is not considered a parameter of concern with these industrial discharges. As such, the monitoring for fecal coliform is waived at all outfalls except Outfall 111.

Waiver Request Dominion requests that sampling for Tributyltin (TBT) be waived.

Staff Response TBT is a parameter of concern associated with ship maintenance/ship yard facilities. The industrial activities associated with the power plant do not involve ship maintenance/ship yard facilities. As such, the monitoring for TBT is waived.

Sampling Request Dominion proposes to complete Form 2A, Part A. 12 for internal Outfall 111 utilizing existing Discharge Monitoring Report (DMR) data generated from January 2008 - December 2010 and performing a minimum of one sample analysis for any remaining parameters.

Staff Response EPA Form 2A, Part A.12 requires at a minimum, that effluent testing data be based on at least three samples and be no more than four and one-half years apart. As such, staff has no objection to the sampling proposal for internal Outfall 111.

VA0052451 Response to Waiver Request Page 3 of 3 Sampling Request Dominion requests that intake samples be representative of Outfall 016.

Staff Response The existing permit authorizes representative sampling for the intake and Outfall 016. Per the permit, intake data may be submitted to represent Outfall 016. As such, staff has no objection to intake samples being representative of Outfall 016.

Sampling Request Dominion requests that Outfall 020 samples be representative of Outfall 021.

Staff Response The existing permit does not authorize representative sampling of Outfall 020 for Outfall 021. Per the permit, intake data may be submitted to represent Outfall 021, not Outfall 020. As such, staff objects to Outfall 020 being representative of Outfall 021.

SamplingRequest Dominion requests that Outfall 104 samples be representative of Outfall 013.

Staff Response The existing permit authorizes representative sampling for Outfall 104 and Outfall 013. Per the permit, Outfall 104 data may be submitted to represent Outfall 013. As such, staff has no objection to Outfall 104 being representative of Outfall 013. Because Outfall 013 is a direct discharge to Lake Anna, Dominion shall monitor internal Outfall 104 in accordance with the requirements of EPA Form 2C.

Additionally, DEQ requests that Dominion sample Outfall 001 for all GC/MS Fraction -Pesticides found in Part V.C of EPA Form 2C, even if believed absent.

If you have any questions, please contact Susan Mackert at (703) 583-3853 or by email at susan.mackert@deq.virginia.gov.

The likelihood is low and is primarily associated with storm water drainage areas and equipment / operations. within those drainage areas. Please refer to Appendix C for general equipment locations, drainage patterns, and directions relevant to each storm water outfall.

The following areas where evaluated on whether storm water comes into direct contact with the material identified and whether the runoff has Best Management Practices (BMPs) to minimize direct discharges from Storm Water Outfalls.

___________ .This rmessage! has been fo1rw/ardled.,

Just as I expected, DEQ is just requesting us to keep them updated.

FYI - was conducting his Storm Water Dry Weather Evaluation and found SW Outfall 022 was discharging with an estimated flow of 5 gpm. The water appears clean is suspected to be from a nearby domestic line or groundwater (both of which are listed in the VPDES as Allowable Non-Storm Water). The station will be testing both the SW water and the domestic water for comparison and characterization.

bcc Subject Fw: North Anna Special Sampling for Storm Water Outfall 022 Randy, The attached email contains the results of our water quality comparison between North Anna Power Station's Storm Water Outfall 022 and the nearby groundwater well. Please note, the water from Outfall 022 is better than the groundwater collected. The groundwater analysis appears to be influenced by the Total Dissolved Solids (TDS) (GW - 4 x higher), when setting the TDS equal, the detections between the SW Outfall and GW appear to be similar. Storm Water Outfall 022's analyticals do not exceed the Facility's Water Quality Criteria / Waste Load Allocations limits, no major concerns with the continues discharge from this outfall..

Please print the results.along with the isotopic results and place in the Station's SWPPP for documentation.

Sincerely, Rick Woolard Dominion Generation (EES)

Attachment G Additional Clean Water Act Requirements For NPDES Permit Applications

§122.21(r) Requirements At 72 FR 37109, July 9, 2007, §122.21(r)(1)(ii) and (r)(5) were suspended.

§125.95(b) Requirements At 72 FR 37109, July 9, 2007, §125.95 was suspended.

Additional Information In accordance with the 2007 VPDES Permit, Part I.E.16, the Impingement Mortality Characterization Study for North Anna Power Station was submitted to the DEQ - Northern Regional Office on October 16, 2008.

North Anna Power Station currently operates under a Clean Water Act (CWA) §316(a) thermal variance.

See Attachment H for additional information.

Attachment H Permit Requests

SubstantiallyIdentical Outfalls Part I.A.3, 14, 16, 17, and 18 contain a statement regarding substantially identical outfalls:

Discharge data from Outfall [number] shall be used to represent Outfall [number]. As written, these special conditions require that effluent from one outfall be reported for another outfall (i.e.

sampling and reporting effluent data from the actual outfall is not allowed). While Dominion wishes to continue utilizing substantially identical outfalls, we request that these Special conditions be written to allow additional flexibility with respect to analytical samples; such flexibility is needed, for example, in the event that the representative outfall is either unavailable, or not discharging, when the other outfall is discharging. Potential permit language below has been included for your consideration: Outfall XXX is substantially identical to Outfall YYY; discharge data from Outfall XXX may be used to represent Outfall YYY.

Continuance of 316(a) Variance North Anna Power Station currently operates under a Clean Water Act (CWA) §316(a) thermal variance. Previously, the State Water Control Board determined that effluent limitations more stringent that the thermal limitations include in the existing permit were not necessary to assure the projection and propagation of a balanced indigenous community of shellfish, fish, and wildlife in Lake Anna and the North Anna River downstream of the lake. The facility operations have not significantly increased heat input, and the station's thermal loading to the lake from Units 1 and 2 is not expected to increase. Additionally, the annual biological reports, submitted under Part I.E.15, indicate that Lake Anna and the Lower North Anna River continue to support a well-balanced ecological community. Accordingly, Dominion believes that the data generated during our §316(a) demonstration studies remain representative for Lake Anna and the North Anna River and for our station operations; we therefore, request continuance of this variance.

Removal of Stormwater Outfalls 023 and 026 Dominion requests that stormwater Outfalls 023 and 026 be removed from the VPDES permit.

While the stormwater in these drainage areas is initially directed into grassy ditches, the flow transitions from a point source flow into sheet flow prior to leaving the Dominion property (i.e.

by the time the stormwater flows from these ditches reaches Lake Anna, it is no longer flowing in a ditch or visible outfall but rather is sheet drainage from the adjacent field.) As stormwater non-point sheet flow is not addressed in VPDES permits, we would like to remove these outfalls. All other regulated storm water outfalls enter the lake or WHTF from a distinct ditch or discharge point.

Post 316(a) MonitoringReport (PartI.E.15)

Permit special condition E.15 requires an annual report on the 316(a) monitoring to be submitted by March 31"t for the previous year's activities. Dominion requests that this report date be revised to allow additional time for data analysis and the report compilation and suggest May 3l1 for the revised date.

Attachment I Supplemental Information

EPA Form 1, Part VIII.

Virginia Electric and Power Company and Old Dominion Electric Cooperative own the North Anna Power Station. Virginia Electric and Power Company operates the facility and is the VPDES permit holder.

EPA Form 1, Part X.

In addition to the Units I and 2 related environmental permits listed in Part X, the facility also obtained the following authorizations:

Type of Permit Permit Number Issuing Agency Impacts to Navigable Waters VWPIO-1256 VA DEQ Impacts to Navigable Waters 10-1256 USACE, VMRC Wetlands Impacts 10-V 1256/ USACE NA02008-2534 Land disturbance ESCP30-80 Louisa County Water' Supply Well n/a VDH, Louisa County EPA Form 2C, Part V.

When analyzing a mixed data set (a mixture of real values and less than quantification level values), a value of one half the quantification level was used to generate the requested calculated value. Mass loadings were calculated using the maximum flow value. In cases where all measured data were less than the quantification level, the mass loading was reported as "less than" the calculated value. When all data were less than the quantification level and different quantification levels were achieved, the average concentration was reported as less than the highest quantification level achieved (e.g. if four sample results were <0.1, <0.01, <0.001, and

<0.005, the average concentration was reported as <0.1).

Maximum 30-day flow values were not available for internal outfalls 103, 105, 108, 110, 112, 113, 114, 115. When available, long term average flows were calculated using the monthly average flows.

Outfalls 107, 115, and 021 did not discharge during the 2008 - 2010 monitoring period. Data from the 2005-2007 monitoring period was used to complete Part V for Outfall 107. However, Outfalls 021 and 115 have not discharge in the last two permit terms (2005 - August 2011). For Outfall 115, the permit instructs that Outfall 108 data may be utilized; accordingly, Part V. for this outfall was completed with Outfall 108 data. Outfall 021 was deemed substantially identical to the intake so intake data collected in 2011 was used to complete this section of the application for Outfall 021.

Dominion utilized the DEQ standard protocol for determining seasonal temperature periods (see the temperature graph below). The winter temperature months were determined to be November

- April with summer months as May - October. These seasons were used to determine the summer and winter temperatures for Outfall 001 presented in Part.V.A. I.g and h.

In accordance with the approved Sampling Waiver Request (see Attachment D), EPA Form 2A was completed for Outfall 111 (treated effluent from the wastewater plant) as opposed to including EPA Form 2C, Part V pages.

For Outfall 104, only the parameters required on the DMR are reported for Part V; however, the data utilized to complete this section for Outfall 013 are the analytical results from Outfall 104 samples as Outfall 013 is substantically identical to Outfall 104.

Part V.A.4 (Intake) was compelted only for Outfall 001; however this intake data is representative of the intake water quality for Outfalls 001, 009, 013, 016, 020, and 021.

The two most common isotopes of radium in water are radium-226 (the most common) and radium-228. Radium-226 decays by the emission of an alpha particle. Radium-228 decays by the emission of a beta particle. Gross alpha particle activity, which is a measure of the total amount of alpha radiation given off by the water, can be used as a screening tool to indicate the presence of radium-226 in a water sample. With this in mind, the amount of radium-226 present in the sample would not be expected to exceed the total alpha-particle activity. Similarly, since radium-228 is a beta emitter the total beta radiation could be used a worse case estimate of the amount of radium-228. Typically, only if the amount of total alpha-particle activity measured is greater than 5 pCi/L, testing for radium-226 and radium-228 is necessary. Thus, while the sample plan submitted to the DEQ proposed analytical testing of Radium-226 and total Radium, this testing was not performed as the results of the Gross Alpha particle activity and Gross Beta activity were less than 5 pCi/L.

EPA Form 2A, A.12.

The reported summer and winter temperature seasons were established as described above (i.e.

summer being May - October and winter being November - April). Temperature is measured weekly in the aeration basin as a process control measure, and the effluent temperature is not expected to vary substantially from the aeration basin temperature. The seasonal temperature values reported on the Form 2A are those temperatures taken in the aeration basin from January -

August 2011. The 9 0 th percentile value was 27.6 'C while the 10th percentile value was 8.2 0C.

Three effluent temperature measurements were taken as well as aeration basin temperatures and are presented in the table below.

Date Aeration Basin Temperature (°C) Effluent Temperature (0C) 9/9/11 26.4 26.9 9/10/11 27.1 26.6 9/13/11 26.8 26.2 In a conversation with DEQ - Northern Regional Office on September 7, 2011, it was determined that the effluent quality from the sewage treatment plant is not expected to vary seasonally with respect to bacteria concentrations. Accordingly, three fecal coliform samples were collected and analyzed on 8/4/11, 9/20/11, and 10/4/11.
