MEMORANDUM

TO:	Steam Electric Rulemaking Record

FROM:	Dan-Tam Nguyen

DATE:	September 30, 2015

SUBJECT:	Pollutants of Concern Analysis Methodology for FGD Wastewater, Combustion Residual Leachate, and Gasification Wastewater

	ERG is providing technical support to the U.S. Environmental Protection Agency's Office of Water, Engineering and Analysis Division (EAD) for development of effluent limitations guidelines and standards (ELGs) for the Steam Electric Power Generating Industry. This memorandum describes EPA's methodology for identifying Pollutants of Concern (POCs) in FGD wastewater, combustion residual leachate, and gasification wastewater.
Introduction
	As part of the final rulemaking, ERG reviewed characterization data for untreated FGD wastewater (FGD purge), combustion residual leachate, and gasification wastewater to identify which pollutants are present in these wastewaters at a sufficient concentration and frequency to be considered treatable. The pollutants that meet these criteria are identified as POCs.  ERG identified POCs separately for each wastestream. Only pollutants identified as POCs are considered in EPA's subsequent pollutant loadings and removals evaluations.  This memorandum only discusses the POC analyses for FGD wastewater, combustion residual leachate and gasification wastewater; the POC analyses for fly ash and bottom ash transport water are discussed separately in Bottom Ash and Fly Ash Pollutants of Concern (POC) Analysis Methodology Memorandum (DCN SE04745).
POC Analysis Methodology
For the proposed rulemaking, EPA conducted the POC analysis by comparing the untreated wastewater sample concentrations to the baseline values that were developed for the 2000 Centralized Waste Treatment (CWT) Industry Effluent Limitations Guidelines [U.S. EPA, 2000; ERG, 2013]. In response to public comments, EPA conducted the analysis for the final rule by comparing sample concentrations to the sample-specific quantitation limit (QL). In the case of FGD wastewater, combustion residual leachate, and gasification wastewater, EPA only used data that included the associated QLs. The QL is often referred to in ELG support documents as the reporting limit. Use of the QL provides a more accurate representation of POCs in untreated wastewater for the following reasons:

 The QL is sample-specific and can vary for a given pollutant between samples. The QL provides a direct comparison to the sample result because it accounts for analytical adjustments made in the determination of the sample result.
 The analytical methods used to determine the sample results and QLs are those used for the Steam Electric rulemaking (i.e., EPA Methods 200.7, 200.8 with collision cell, and 1631E) and are capable of achieving QLs that are lower than the baseline values from CWT for many priority and nonconventional pollutants (e.g., arsenic, cadmium, chromium, selenium, magnesium, manganese). In contrast, for example, the CWT baseline values for metals were developed based on instrument detection limits for EPA Method 1620.
	EPA used the analytical data from the data sources described in Section 3 to identify POCs in each of the wastestreams. EPA reviewed the sample results to identify POCs, which EPA defined as those pollutants detected at greater than or equal to 10 times the QL in at least 10 percent of all untreated wastewater samples for each wastestream. Using 10 times the QL as a screening threshold ensures the untreated wastewater concentrations are high enough to quantify the degree of pollutant removal resulting from treatment processes, such as chemical or biological treatment for FGD wastewater.

Data Sources Used in the POC Analysis
	EPA's data collection efforts produced data sets from EPA and/or industry-submitted data sources. This section describes the data sources used in the POC analysis for each of the wastestreams. ERG's data quality review procedures for the data collected and used by EPA are outlined in Development Memorandum for the Steam Electric Analytical Database for the Final Rule (DCN SE05876). The data are included in the Steam Electric Analytical Database for the Final Rule (DCN SE05359).

FGD Wastewater
	EPA evaluated sources of analytical data for untreated FGD wastewater, which are summarized in Table 3-1. These data sources are further described in Development Memorandum for the Steam Electric Analytical Database for the Final Rule (DCN SE05876). Because the POC analysis compares the sample results to the QLs, ERG reviewed and excluded any sample results that did not include sample-specific QLs.

a  -  EPA samples from Brindisi and Monfalcone were not used in the POC analysis because they are not representative of plants operating within the United States.
b  -  Only non-detect samples had reported sample QLs. EPA determined that excluding only the detected samples which did not include sample QLs would skew the results of the POC analysis; therefore, EPA excluded the entire analytical data sets for these plants.
      In summary, EPA's data set used to identify POCs in untreated FGD wastewater included:

 EPA Field Sampling Program. EPA included four samples of untreated FGD wastewater from seven steam electric power plants operating FGD wastewater treatment systems for a total of 28 samples. Sample results include 38 analytes, including priority, conventional, and nonconventional pollutants.
 EPA CWA 308 Monitoring Program. EPA included data from eight plants that each collected three- to four-day samples of untreated FGD wastewater. The data set included a total of 31 samples with sample results for 37 analytes, including priority, conventional, and nonconventional pollutants.
 Steam Electric Public Comments on the Proposed Rulemaking. EPA included analytical data for untreated FGD wastewater from one plant that submitted results for a total of 159 samples, including data for the priority pollutants arsenic, mercury, and selenium.
 EPA Data Request. EPA included analytical data for untreated FGD wastewater from three plants for a total of 189 samples, including results for the priority and nonconventional pollutants.
Combustion Residual Leachate
	As part of industry responses to the Questionnaire for the Steam Electric Power Generating Effluent Guidelines (Steam Electric Survey) (DCN SE05903), EPA received analytical data for 322 samples of combustion residual leachate (from landfill and impoundment leachate management units). Table 3-2 summarizes the plants that provided analytical data for this wastestream. Upon further review of the data, EPA excluded samples that represented retired combustion residual leachate management units (49 samples) because the data are not representative of the wastestream regulated by the final rule. Additionally, EPA excluded several samples where the sample QLs were not available (31 samples).

	In summary, EPA's data set used to identify POCs in combustion residual leachate included data from 33 steam electric power plants with analytical results for 30 analytes from 246 samples (173 landfill leachate samples and 73 impoundment leachate samples).

Note: Samples from retired units are excluded from the POC analysis.
a  -  All samples contained QLs with the exception of three sample results for one pollutant. EPA excluded these sample results from the POC analysis.
b  -  All samples contained QLs with the exception of one sample result for one pollutant. EPA excluded this sample result from the POC analysis.

Gasification Wastewater
	During EPA's field sampling activities, EPA collected 20 gasification wastewater samples for 37 analytes from two plants: Polk Power Station and Wabash River Station. Gasification wastewater from these plants includes the following wastestreams: neutralized weak acid wastestream, vapor compression evaporator influent, compression evaporator influent, RCC(R) evaporator influent, sour water treatment influent, and steam stripper effluent. All 20 samples included sample QLs and were included in the POC analysis for gasification wastewater.

Results of POC Analyses
	Using the methodology outlined in Section 2, EPA conducted separate POC analyses for each of the wastestreams.
FGD Wastewater
	Table 4-1 presents the number of samples analyzed for each pollutant in FGD wastewater, the number of sample results that were not detected above the sample QL, and the number and percentage of sample results that were detected at a concentration greater than or equal to ten times the sample-specific QL. EPA identified 31 POCs for FGD wastewater (listed in Table 4-2).

Policy Act (NEPA) review process, the Commission takes into account
concerns the public may have about proposals and the environmental
impacts that could result from its action whenever it considers the
issuance of a Certificate of Public Convenience and Necessity. This
gathering of public input is referred to as ``scoping.'' The main goal
of the scoping process is to focus the analysis in the environmental
document on the important environmental issues. Additional information
about the Commission's NEPA process is described below in the NEPA
Process and Environmental Document section of this notice.
    By this notice, the Commission requests public comments on the
scope of issues to address in the environmental document. To ensure
that your comments are timely and properly recorded, please submit your
comments so that the Commission receives them in Washington, DC on or
before 5:00 p.m. Eastern Time on May 19, 2022. Comments may be
submitted in written form. Further details on how to submit comments
are provided in the Public Participation section of this notice.
    Your comments should focus on the potential environmental effects,
reasonable alternatives, and measures to avoid or lessen environmental
impacts. Your input will help the Commission staff determine what
issues they need to evaluate in the environmental document. Commission
staff will consider all written comments during the preparation of the
environmental document.
    If you submitted comments on this project to the Commission before
the opening of this docket on April 12, 2022, you will need to file
those comments in Docket No. CP22-162-000 to ensure they are considered
as part of this proceeding.
    This notice is being sent to the Commission's current environmental
mailing list for this project. State and local government
representatives should notify their constituents of this proposed
project and encourage them to comment on their areas of concern.
    If you are a landowner receiving this notice, a pipeline company
representative may contact you about the acquisition of an easement to
construct, operate, and maintain the proposed facilities. The company
would seek to negotiate a mutually acceptable easement agreement. You
are not required to enter into an agreement. However, if the Commission
approves the project, the Natural Gas Act conveys the right of eminent
domain to the company. Therefore, if you and the company do not reach
an easement agreement, the pipeline company could initiate condemnation
proceedings in court. In such instances, compensation would be
determined by a judge in accordance with state law. The Commission does
not subsequently grant, exercise, or oversee the exercise of that
eminent domain authority. The courts have exclusive authority to handle
eminent domain cases; the Commission has no jurisdiction over these
matters.
    Equitrans provided landowners with a fact sheet prepared by the
FERC entitled ``An Interstate Natural Gas Facility On My Land? What Do
I Need To Know?'' which addresses typically asked questions, including
the use of eminent domain and how to participate in the Commission's
proceedings. This fact sheet along with other landowner topics of
interest are available for viewing on the FERC website (www.ferc.gov)
under the Natural Gas Questions or Landowner Topics link.

Public Participation

    There are three methods you can use to submit your comments to the
Commission. Please carefully follow these instructions so that your

Summary of the Proposed Project

    Equitrans proposes to plug and abandon five natural gas injection/
withdrawal wells (Wells 603791,

603792, 603793, 603795, and 603797) and abandon in place the pipelines
associated with the five wells. Equitrans also proposes to disconnect
and remove aboveground appurtenances along with a portion of the well
line that is within each well site workspace.
    On March 20, 2019, the Commission issued an order approving
abandonment by sale of eighteen natural gas injection/withdrawal wells
and associated well lines and appurtenances at the Swarts Complex under
Docket No. CP18-549-000. Equitrans is requesting amendment of this
order for authorization to abandon five of the eighteen wells, as
described above.
    The general location of the project facilities is shown in appendix
1.\1\

    \1\ The appendices referenced in this notice will not appear in
the Federal Register. Copies of the appendices were sent to all
those receiving this notice in the mail and are available at
www.ferc.gov using the link called ``eLibrary''. For instructions on
connecting to eLibrary, refer to the last page of this notice. At
this time, the Commission has suspended access to the Commission's
Public Reference Room due to the proclamation declaring a National
Emergency concerning the Novel Coronavirus Disease (COVID-19),
issued by the President on March 13, 2020. For assistance, contact
FERC at [email protected] or call toll free,<PHONE_NUMBER>
or TTY<PHONE_NUMBER>.
---------------------------------------------------------------------------

Land Requirements for Construction

    Abandonment of the proposed facilities would disturb about 4.4
acres of land, including about 2.4 acres of temporary workspace and
about 2.0 acres of existing permanent or new temporary access roads.
Following the abandonment, the permanent access roads would be left
intact for future use in right-of-way monitoring. Equitrans would
remove the temporary access roads and return the areas to pre-
abandonment conditions and use.

NEPA Process and the Environmental Document

    Any environmental document issued by the Commission will discuss
impacts that could occur as a result of the construction and operation
of the proposed project under the relevant general resource areas:
     Geology and soils;
     water resources and wetlands;
     vegetation and wildlife;
     threatened and endangered species;
     cultural resources;
     land use;
     air quality and noise; and
     reliability and safety.

    Commission staff will also evaluate reasonable alternatives to the
proposed project or portions of the project and make recommendations on
how to lessen or avoid impacts on the various resource areas. Your
comments will help Commission staff identify and focus on the issues
that might have an effect on the human environment and potentially
eliminate others from further study and discussion in the environmental
document.
    Following this scoping period, Commission staff will determine
whether to prepare an Environmental Assessment (EA) or an Environmental
Impact Statement (EIS). The EA or the EIS will present Commission
staff's independent analysis of the issues. If Commission staff
prepares an EA, a Notice of Schedule for the Preparation of an
Environmental Assessment will be issued. The EA may be issued for an
allotted public comment period. The Commission would consider timely
comments on the EA before making its decision regarding the proposed
project. If Commission staff prepares an EIS, a Notice of Intent to
Prepare an EIS/Notice of Schedule will be issued, which will open up an
additional comment period. Staff will then prepare a draft EIS which
will be issued for public comment. Commission staff will consider all
timely comments received during the comment period on the draft EIS and
revise the document, as necessary, before issuing a final EIS. Any EA
or draft and final EIS will be available in electronic format in the
public record through eLibrary \2\ and the Commission's natural gas
environmental documents web page (https://www.ferc.gov/industries-data/natural-gas/environment/environmental-documents). If eSubscribed, you
will receive instant email notification when the environmental document
is issued.

Consultation Under Section 106 of the National Historic Preservation
Act

    In accordance with the Advisory Council on Historic Preservation's
implementing regulations for section 106 of the National Historic
Preservation Act, the Commission is using this notice to initiate
consultation with the applicable State Historic Preservation Office(s),
and to solicit their views and those of other government agencies,
interested Indian tribes, and the public on the project's potential
effects on historic properties.\4\ The environmental document for this
project will document findings on the impacts on historic properties
and summarize the status of consultations under section 106.
---------------------------------------------------------------------------

    \4\ The Advisory Council on Historic Preservation's regulations
are at Title 36, Code of Federal Regulations, Part 800. Those
regulations define historic properties as any prehistoric or
historic district, site, building, structure, or object included in
or eligible for inclusion in the National Register of Historic
Places.
---------------------------------------------------------------------------
