1.0 Introduction

This Closure Monitoring Verification Report provides groundwater monitoring information supporting the

certification of closure of the Black Dog Generating Plant coal combustion residuals (CCR) units in

accordance with the United States Environmental Protection Agency (EPA) rule to regulate the disposal of

CCR as solid waste [CCR Rule: Subtitle D of the Resource Conservation and Recovery Act (RCRA), 40 CFR

Parts 257 and 261 (EPA, 2015a)]. Under the provision for closure by removal of CCR, §257.102(c) of the

CCR Rule states:

Closure by removal of CCR: An owner or operator may elect to close a CCR unit by removing and

decontaminating all areas affected by releases from the CCR unit. CCR removal and

decontamination of the CCR unit are complete when constituent concentrations throughout the CCR

unit and any areas affected by releases from the CCR unit have been removed and groundwater

monitoring concentrations do not exceed the groundwater protection standard established pursuant

to § 257.95(h) for constituents listed in appendix IV to this part.

1.1 Background

Northern States Power Company, a Minnesota corporation doing business as Xcel Energy (NSPM),

formerly operated three CCR units, referred to as Ash Ponds 1, 2, and 3 (collectively the Ash Ponds) at its

Black Dog Generating Plant (Plant or Site), located in Burnsville, MN (Figure 1). Coal operations ceased at

the Plant on April 16, 2015 and CCR discharges to the Ash Ponds ceased prior to October 19, 2015. The

remaining wastewater discharged from the Plant was directed to an alternate discharge system in 2016,

thereby allowing for closure of the Ash Ponds and their associated components. NSPM drained the Ash

Ponds and removed CCR in accordance with the Ash Pond Closure Plan (Barr, 2016) by December 12,

2016. The removal of CCR throughout the CCR Units is documented in the CCR Surface Impoundment

Closure Certification Report, Ash Ponds 1-3 (Barr, 2017a).

1.2 Report Organization

This report is organized into the following additional sections:

Section 2.0 of this report documents the process for establishing groundwater protection

standards (GWPS) pursuant to §257.95(h) for constituents listed in appendix IV to the CCR Rule.

Section 3.0 of this report describes hydrogeologic conditions and documents that groundwater

monitoring concentrations do not exceed the GWPS, demonstrating that the Site meets the

requirements for closure in accordance with §257.102(c).

Section 4.0 includes references.

2.0 Groundwater Protection Standards

As stated in the CCR Rule (as modified by Amendments to the National Minimum Criteria [Phase One, Part

One], July 30, 2018), GWPS are to be established in accordance with §257.95(h), which states:

(h) The owner or operator of the CCR unit must establish a groundwater protection standard for

each constituent in appendix IV to this part detected in the groundwater. The groundwater

protection standard shall be:

(1) For constituents for which a maximum contaminant level (MCL) has been established

under §§ 141.62 and 141.66 of this title, the MCL for that constituent;

(2) For the following constituents:

(i) Cobalt 6 micrograms per liter (µg/l);

(ii) Lead 15 µg/l;

(iii) Lithium 40 µg/l; and

(iv) Molybdenum 100 µg/l

(3) For constituents for which the background level is higher than the levels identified under

paragraphs (h)(1) and (h)(2) of this section, the background concentration.

Therefore, to develop values for GWPS, the “background concentration” needs to be determined for each

appendix IV constituent and compared to the MCL and the values in (h)(2) above. The following

subsections provide details on the baseline monitoring used to develop the background concentrations

and the development of GWPS.

2.1 CCR Monitoring System

NSPM established a multiunit groundwater monitoring system for the former CCR Units in 2017 for use in

conducting baseline monitoring to establish background conditions, and then for use in final closure

monitoring to document GWPS were met. The monitoring system included seven wells to characterize

background groundwater conditions at the Site and five wells located downgradient of the former CCR

Units for closure monitoring. The monitoring system is documented in the Groundwater Monitoring

System Certification Report (Barr, 2019a) and shown on Figure 2.

2.2 Baseline Data Collection

During the baseline groundwater monitoring period, December 2017 through October 2018, each

monitoring well was sampled a minimum of eight times. Each sampling event included measuring water

levels to evaluate the groundwater flow direction at the Site and the collection of samples for laboratory

analysis of parameters listed in Appendices III and IV of the CCR Rule. Groundwater samples were also

analyzed for additional parameters (e.g., major cations and anions) to verify the appropriateness of the

monitoring network.

The groundwater samples were collected and analyzed in accordance with the Sampling and Analysis Plan

(SAP; Barr, 2017b). Sampling services were provided by Pace Analytical Services of Minneapolis, Minnesota

(Pace). The samples were analyzed by the following labs using the appropriate methodologies: Xcel

Energy’s Minneapolis Testing Laboratory and Pace Analytical Services located in Greensburg,

Pennsylvania. Copies of the laboratory reports with the baseline groundwater data are included in

Appendix A.

2.2.1 Data Quality Review

The baseline groundwater data were reviewed in general accordance with Barr’s data quality review

standard operating procedures (SOPs) included in the SAP (Barr, 2017b). The data quality reviews included

a check for completeness, field quality control, and laboratory quality control. Details from the data

quality review are included in Appendix B. The baseline groundwater data were determined to be

acceptable as qualified with the exception of the following rejected data:

Well Sample Date Rationale Details

W600A May 8, 2018 Elevated turbidity (200 NTU) Analytical data from this well / sampling events were

rejected and are not included in the baseline data set. W600A June 12, 2018 Elevated turbidity (54 NTU)

W601A February 7, 2018 Elevated turbidity (320 NTU) Analytical data from this well / sampling event were

rejected and are not included in the baseline data set.

These wells were resampled on two occasions for which the data was determined to be acceptable for

use.

2.3 Background Concentrations

Background concentrations for each appendix IV parameter were determined based on results of

background well sampling during the CCR baseline monitoring period. Background concentrations were

established in accordance with the methods outlined in the CCR Groundwater Statistical Analysis Plan

(Barr, 2019c). The methods used to establish background concentrations are discussed below, and

detailed information regarding the background data assessment is provided in Appendix C.

2.3.1 Background Data Set

The background data set (Table C-1) includes monitoring results from background well sampling

completed during the baseline monitoring period. This data set was used to establish background

concentrations for the constituents listed in appendix IV of the CCR Rule. Representativeness of the data

was reviewed by performing outlier testing, as described in Appendix C. All values were retained for use in

the background data set.

2.3.2 Background Calculation

Consistent with the CCR Rule (§257.93 (f)), statistical methods were used to evaluate the background data

set and establish background concentrations (Barr, 2019c). Background concentrations for each appendix

Page 9: CCR Monitoring Closure Verification Report · closure verification groundwater data were reviewed and determined to be acceptable with qualifications, as presented in Appendix B.

4

IV parameter were calculated based on the upper prediction limit (UPL) of the background data set, with

95% probability and two future measurements, coinciding with the two closure monitoring events.

Prior to computing the UPL, goodness-of-fit testing was performed on the background data set for each

appendix IV parameter to assess whether the data sets fit a normal distribution. For all parameters, the

data set did not fit a normal distribution, therefore, nonparametric methods were used for the statistical

analysis. Goodness-of-fit test results are included in Table C-2 in Appendix C.

The UPL results are shown in Table C-3 in Appendix C.

2.4 Establishment of Groundwater Protection Standards

In accordance with the CCR Rule (§257.95(h)), GWPS were established to be the highest of the following

values: the MCL; the values listed for cobalt, lead, lithium, and molybdenum; or the background

concentrations (UPL), as shown in Table C-2. The GWPS are provided in Table 1.

3.0 Closure Verification

As defined in the CCR Rule (§257.102(c)), closure verification sampling was needed to confirm

groundwater monitoring concentrations do not exceed the GWPS. Closure verification sampling took

place in March and May 2019, and included the measurement of water levels in the monitoring wells to

verify groundwater flow directions at the Site and the collection of samples in downgradient wells for

laboratory analysis and comparison to the GWPS. Groundwater samples were also collected from the

background wells for informational purposes. The samples were analyzed for the parameters listed in

Appendices III and IV of the CCR Rule and additional parameters (e.g., major cations and anions). The

sampling, laboratory analysis, and data quality review methods were consistent with the methods used

during baseline sampling and the SAP, updated at the time of network certification (Barr, 2019b). The

closure verification groundwater data were reviewed and determined to be acceptable with qualifications,

as presented in Appendix B. Closure monitoring laboratory reports are included in Appendix D.

3.1 Groundwater Flow Direction

Maps depicting groundwater contours and flow directions during the closure monitoring events are

attached as Figures 3 and 4. The groundwater flow directions at the Site during these monitoring events

were consistent with flow patterns observed during baseline sampling and the downgradient wells were

positioned hydraulically downgradient of the former CCR units.

3.2 Analytical Results

The concentrations of parameters listed in appendix IV of the CCR rule from downgradient well sampling

during the two closure monitoring events are compared to GWPS in Table 2. No appendix IV parameters

were detected in downgradient wells at concentrations above the GWPS established pursuant to

§257.95(h).

3.3 Conclusion

Groundwater monitoring at the Site was conducted in accordance with the CCR Rule to support closure of

the CCR units. Closure monitoring results were below GWPS, therefore the Site meets the requirements

for closure of the CCR units in accordance with §257.102(c).

Appendix B: Data Quality Assurance / Quality Control Review

A review of the quality control data was conducted to assess the validity of the analytical results for the

groundwater samples collected during the CCR baseline monitoring (2017-2018) and closure verification

events (2019) at the Black Dog Generating Plant (Plant or Site) located in Burnsville, Minnesota. The samples

were collected and analyzed for the parameters listed in Appendices III and IV of the CCR Rule. Groundwater

samples were also analyzed for additional parameters (e.g., major cations and anions) to verify the

appropriateness of the monitoring network. This review was performed in accordance with Barr Engineering’s

Standard Operating Procedures (SOPs) for data evaluation, which are based on The National Functional

Guidelines for Organic and Inorganic Data Review (USEPA, 2008 and 2010). The majority of the analyses were

performed by Xcel Energy’s Minneapolis Testing Laboratory (Xcel Minneapolis) located in Minneapolis,

Minnesota with the radium analysis performed by Pace located in Greensburg, Pennsylvania.

Both field sampling and laboratory analytical procedures were examined in the review of the sampling event.

Field sampling procedures were examined utilizing field blank samples and field (masked) duplicate sample

analyses. Laboratory procedures were evaluated utilizing technical holding times, preservation, method blank

samples, accuracy data, precision data, and data package completeness.

Field sampling procedures

A field blank sample was collected during each of the eight baseline monitoring and two closure verification

events. The field blank collected with the samples for the December 11th, 2017 event had a detection of radium

226 and the following sample detections were qualified (b) as potential false positive detections: W504B,

W602A, W14A, W601A, and W604A. No other target compounds were detected above the reporting limits

(RLs) in the field blank samples.

Field (masked) duplicate sample results were evaluated by calculating the Relative Percent Difference (RPD)

values for compounds where both the native and field duplicate sample had concentrations reported above

the RL. The RPD formula is as follows:

1002/)(

DS

DSRPD

Where: RPD = relative percent difference

S = original sample result

D = duplicate sample result

Verification\Appendices\B-QAQC\Appendix B QAQC Memo_071519.doc

A field duplicate pair was collected during each of the eight baseline monitoring and two closure verification

events and the data is shown in Table B-1. The acceptance criteria used for the field duplicate samples data

precision (30% RPD) was based on Barr’s SOPs for routine data evaluation. The field duplicate data met the

RPD criteria for precision.

The field parameters were also reviewed for each event. There were three instances where the turbidity was

significantly elevated (< 50 NTU) and the associated sample data (W600A - May 8 and June 12, 2018 and

W601A - February 7, 2018) was rejected (**) based on this. As discussed in the report, these sample locations

were resampled in order to have a complete baseline dataset.

Laboratory Procedures

Technical holding times and preservation were evaluated for each sample and target parameter based on

United States Environmental Protection Agency (USEPA) and method recommendations. The technical holding

times were within these recommendations for all of the analyses, and the groundwater samples arrived at the

laboratory at the correct temperatures and with the correct chemical preservatives.

Method blanks were analyzed by the laboratory for each parameter. The method blank tested with the

samples for the July 23-25, 2018 event had a detection of radium 228 and the following sample detections

were qualified (b) as potential false positive detections: W504A, W504B, W14A, W510A, and the W50A Field

Duplicate. No other target compounds were detected above the RL in the method blank samples.

The accuracy and precision data review included evaluation of laboratory control spike (LCS), matrix spike (MS),

matrix spike duplicate (MSD), and laboratory duplicate samples. Accuracy was evaluated by comparing

laboratory percent recoveries from LCS, MS, and MSD samples to laboratory acceptance criteria. Precision was

evaluated by calculating the RPD of the MS/MSD and laboratory duplicate sample pairs.

The LCS samples displayed acceptable accuracy when compared to the laboratory acceptance criteria in the

majority of instances. The LCS tested for laboratory pH with the samples included in laboratory work order

MDK0180, had a percent recovery that exceeded the laboratory acceptance criteria and the associated samples

results taken on November 12, 2018 (W600A and W601A) were qualified (*) as estimated. Also, an LCS

associated with the closure work order MEE0179 analysis of fluoride had an LCS that was only slightly above

acceptance recovery (by one percent) and no data was qualified based on this slight deviation. The remaining

LCS samples displayed accuracy within laboratory acceptance limits.

The laboratory included MS/MSD samples tested from project and non-project samples in each work order.

Only the MS/MSD samples taken from project samples were evaluated compared to project data. In instances

Verification\Appendices\B-QAQC\Appendix B QAQC Memo_071519.doc

where a duplicate accuracy sample was analyzed (MSD), the associated sample data results were not qualified

if only the RPD or one of the percent recoveries were outside acceptance criteria. In addition, where MS

recoveries failed acceptance criteria and the native sample concentration was significantly greater than the

spike added (greater than four times), the spike recovery could not be accurately evaluated, therefore the

criteria did not apply and acceptance of the sample results were based on the acceptable LCS data. The

MS/MSDs displayed accuracy and/or precision within laboratory acceptance criteria or the deviation was

considered minor (less than five percent).

The laboratory included laboratory duplicate samples tested from project and non-project samples in each

work order. Only the duplicate samples taken from project samples were evaluated compared to project data.

The calculated RPD was compared against the laboratory criteria. Only duplicate pairs that were detected

significantly above the RL (greater than five times) were evaluated as the RPD is exaggerated from results close

to the RL. All of the evaluated laboratory duplicate data met the RPD criteria for precision.

Data completeness was evaluated by comparing the analyses requested with the data package as received.

There were multiple events where the sample location was labeled incorrectly as W514A on the COCs and

associated laboratory reports when the correct location should have been W514B; the laboratory reports have

been revised to note the correction and the EQuIS database and associated tables reflect the correct sample

location of W514B. Neither of these wells are in the monitoring network and the project result were

unaffected.

Conclusion

The data are deemed acceptable for the purposes of this project with the qualifications assigned during the

data evaluation process.

Subject: Development of Groundwater Protection Standards

Date: July 2019

Project: Black Dog Generating Plant, Burnsville, Minnesota

Statistical analyses were conducted using the Sanitas software package (version 9.6, produced by Sanitas

Technologies of Loveland, CO). The Sanitas software is set up to conduct statistical analyses according to

the U.S. Environmental Protection Agency (EPA)’s 2009 Statistical Analysis of Groundwater Monitoring Data

at RCRA Facilities: Unified Guidance (Unified Guidance; EPA 530/R-09-007). The statistical analyses also

followed the CCR Groundwater Statistical Analysis Plan (Barr, 2019c).

The background data (Table C-1) were loaded into Sanitas for statistical analyses. Unless otherwise

specified, an alpha of 0.05 was used in statistical tests.

The normality of the pooled data from the seven background wells was assessed by the Shapiro-Francia

test (Unified Guidance, Chapter 10). The results of the normality testing in combination with the fraction

of data below analytical reporting limits (Table C-2) were used to determine whether parametric or non-

parametric methods would be used. None of the pooled background datasets were determined to fit a

normal distribution, so non-parametric methods were used for subsequent statistical analysis.

Outlier testing was conducted on pooled data from the seven background wells using the Tukey hinge

screening method with an interquartile range multiplier of 3 (Unified Guidance, Chapter 12). Values less

than three times the median and values below analytical reporting limits were not included as outliers. For

suspected outliers identified in the pooled background data, individual well-parameter datasets were then

evaluated using Dixon’s test (for normally distributed datasets, based on the Shapiro-Wilk test) or the

Tukey screening method (for non-normally distributed datasets). Values that were identified as outliers in

both the pooled data screening and the well-parameter pair datasets were individually evaluated using

professional judgement to determine whether the values should remain in the background dataset. Values

that were identified as outliers in both the pooled data screening and the well-parameter pair datasets

were individually evaluated for data quality issues and shifts in groundwater population (Barr 2019c). The

values included two chromium samples from W600A (43.1 µg/L on July 24, 2018, and 8.37 µg/L on

September 12, 2018). No data quality issues were identified for these samples, and no trend or shift was

identified in the data. Therefore, consistent with the CCR Groundwater Statistical Analysis Plan (Barr,

2019c), no statistical outliers were removed from the background dataset.

Interwell prediction limits were used to calculate background concentrations. Prediction limits were

calculated assuming two statistical evaluations per year with 15 appendix IV constituents in 5

downgradient wells to yield an annual false positive rate of 0.1 or a per-event false positive rate of 0.05

(40 CFR 257.93(g)(2)).

For datasets with less than 15% of observations below laboratory reporting limits, one-half the detection

limit was substituted for non-detect values. For datasets with between 15% and 50% of observations

below laboratory reporting limits, the Kaplan-Meier method was used for non-detect values. For datasets

with greater than 50% of observations below laboratory reporting limits, non-parametric statistical

methods were used (Unified Guidance, Chapter 15). No evaluation or correction for seasonality was done

because the dataset included less than three years of data (Unified Guidance, Chapter 14).

None of the pooled background datasets follow a normal or log-normal distribution, so the non-

parametric prediction limit of the highest value from the pooled background data was used (Unified

Guidance, Chapter 18).

The upper prediction limit of the pooled background data for each appendix IV constituent was compared

to the maximum contaminant level (MCL) or the levels listed in §257.95(h)(2) (regional screening level,

RSL). The higher of the background concentration and the MCL or RSL was set as the Groundwater

Protection Standard (Table C-3).

The statistical outliers described above are below the upper prediction limits, MCL, and/or RSLs and do

not affect the GWPS.
