Definitions

Darter - Darter is a set of software utilities written by EPA that assist in moving data from other
platforms such as FORMS, Niton, YSI and Scribe to the Region 4 EDD format.

Data Provider - "Data Provider" and "Sampling Company" are defined to be interchangeable with
regard to EDD submittals. The data provider may be defined as the person or agency that organized,
formatted and submitted the electronic data from a sampling event. This may or may not be the
sampling company, particularly when working with historic data. Unless otherwise noted by your
RPM, the prime contractor or grantee is always entered as the Sampling Company for the Samples
and the Data Provider for the Geology EDDs.

Electronic Data Deliverable (EDD) - An Electronic Data Deliverable, or EDD for short is a flat file
format, such as text, Excel, or other tabular file that follows a consistent design meant to organize
information in a useful format. EDD files use a row of headers (typically one to two rows) that
describe what information should be completed in each column the header precedes, and in what
format that data should be entered.

Header Row 1
Header Row 2
Data Row 1
Data Row 2

Scribe - Scribe is a software tool developed by EPA to assist in the process of managing
environmental data. Scribe captures soil, water, air, and biota sampling, observational, and
monitoring field data. Scribe can import electronic data deliverables (EDD) from analytical
laboratories, location data from a global positioning system (GPS), and from exported EQuIS™
EDDs.

Samples and the Data Provider for the Geology EDDs.

.rvf- The ".rvf' file (reference value file) is associated with the EQuIS Data Processor (EDP) from
EarthSoft. This file contains the valid values reference tables used by EDP to populate the drop down
menus used when a specific type of value is required in an EDD, such as the units "mg/kg"
(milligrams per kilogram) or a media code such as "GW" (groundwater). These fields limit the type
of data permitted in certain columns of the EDD, and all the most recent valid values are in the ".rvf'
file. Therefore, it is extremely important to insure you are using the most current file. You should
check the EarthSoft web site to see if your version is current before working on your data.

.zip archive - The ZIP file format is a data compression and archival format that contains one or
more files that have been compressed, to reduce their file size, or stored as-is. Many software utilities
are available to create, modify, or open (unzip, decompress) ZIP files.

ZIP files typically use the file extensions ".zip" or ".ZIP" and the MIME media type application/zip.
However, due to security features at EPA, compressed files with the extension .zip should be
renamed to the extension ".edd."

1.0 INTRODUCTION

The Region 4 Format Guide describes the formats of the various EDD files necessary for properly
preparing, formatting and electronically submitting operation and maintenance (O&M)
environmental data to EPA Region 4 using the EQuIS® Data Processor (EDP) from EarthSoft.
Instructions for obtaining EDP can be found in Section 2.11 of this document. Instructions for using
the EDP are available in the EPA Region 4 EDP Reference Manual. You may obtain instructions
from the manufacturer as well at http://www.earthsoft.com.

While it should be understood that it would be a rare occasion that any one site would require the use
of every possible Electronic Data Deliverable (EDD), and that simultaneously no amount of EDD
files could completely cover the requirements of every possible site, every effort has been made to
create EDD files that incorporate as much useful discreet information as is possible based on the
commonalities of the various sites under the EPA Region 4 purview. Thus, a reasonable effort should
be made by data managers to prepare data to correctly import into the EQuIS database structure when
required to do so. It is also understood that in some rare cases, historical data may lack key
components necessary for complete importation and subsequently may only be partially input, or in
some extremely rare cases not be capable of input at all. The decision to import or not import this
data lies exclusively with EPA Region 4.

1.1	What You Will Find in thisGuide

This document should serve as a reference guide for the individuals who understands the structure of
their own data and the process used to format and import electronic data into management systems
such as EQuIS. In this guide you will find a detailed description of all EDD formats currently used
by EPA Region 4 as well as information for handling formatting issues with historic data.

1.2	What You Will NOT Find in thisGuide

This guide does not contain detailed instructions on how to manage information nor does it contain
directions for importing electronic data into the EPA EQuIS database. This information is contained
in the EPA Region 4 EDP Reference Manual found on EPA Region 4 Superfund's website at

http://www2.epa.gov/superfund/region-4-superfund-electronic-data-submission

You will also not find lessons or instructions on general data management. It is assumed that persons
dealing with data of this nature have some experience and understanding of basic data management
guidelines and software.

1.3	Projects

Before data can be submitted to EPA Region 4, the dataset must be defined as a "proj ect" in the EPA
Region 4 data system. Once this has occurred, the system will generate an E-mail to the data provider
(see below) requesting the data for most fund lead projects. Other type of projects should follow
their statement of work or directive from their RPM. The EDD(s) containing the data are then

USEPA Region 4 Format Guide
Version 1.20 December 2015

-------
attached to this E-mail and returned to EPA Region 4 R4DART. The project defines the numbers of
samples, the media sampled, and the analyses performed (including lab results, field results,
lithology, etc.). Each project will be assigned a unique ID (project ID) to identify the dataset in the
system. Data from a given project can be sent to EPA Region 4 in multiple submittals, if desired.

When multiple laboratories and/or chain-of-custodies are needed for the unique project id, then
multiple proj ect numbers will be assigned under the proj ect ID. Proj ects that are not logged through
R4LIMS or if you have not received your project ID and project numbers, contact R4DART for
further instructions.

1.4	Data Provider

The EPA Region 4 data system defines the "data provider" as the entity preparing and sending the
EDDs to the R4DART. It is the responsibility of the data provider to ensure completeness of the data
submittal, and to correct any errors in the dataset.

1.5	Historical Data

The determination as to the status of data as either "historical" or "current" is at the sole
discretion of the EPA Region 4 DART Coordinator. The data provider is encouraged to become
familiar with and submit Electronic Data Deliverables (EDDs) in accordance with the standard
EPA Region 4 EDP Reference Manual located on the EPA Region 4 web site:

http://www2.epa.gov/superfund/region-4-superfund-electronic-data-submission

EPA Region 4 will require all data providers to submit EDDs in accordance with this manual and
reference guide.

The intent of developing special requirements for historical information is to decrease the burden and
complications associated with reporting in-depth details about data that may have been collected a
number of years ago while retaining the value of the information being reported. EPA recognizes that
some information about data collected in the past may not be readily available and, by reducing the
requirements for electronic historical data, is endeavoring to strike a balance between minimizing the
amount of effort involved in inputting information and maximizing the ability to document remedy
progress.

1.6	Current Data

Data is considered to be "current" if it was collected on or after the deadline specified for the specific
data type and provider outlined in Table 1.1. The data provider should anticipate all future data being
collected for a site on or after the deadline to be submitted according to the site-specific legal order,
on a regular basis (at least annually, semi-annually) or in accordance with this manual.

In addition to the routine data checking performed on all data as it loads into the EPA Region 4
DART system, current data will undergo an additional electronic EPA Region 4 review prior to

USEPA Region 4 Format Guide
Version 1.20 December 2015

-------
being loaded. This may include but not limited to the plotting of submitted locations to verify the
accuracy of the spatial information being submitted.

1.7 Scribe

Samples collected during the course of an Emergency Response that are analyzed using the EPA
Region 4 SESD lab or the CLP will be submitted as Current Data: Fund Lead (See Table 1.1). If
samples are analyzed using a lab hired for the response, that data can be reported directly from Scribe
using the EPA Region 4 macro software utility. Prior to sending the data to R4DART, the created
EPAR4_FieldResults_vl.txt file should first be loaded into the EDP checker to verify if any
additional information needs to be added.

2.0 GENERAL EDD REPORTING REQUIREMENTS

2.1 Defining the Data Submittal

It is important to define what is to be submitted ahead of the data submittal. While it is often not
possible to know precisely how many rows of data may be submitted, it should be possible to
provide a summary of the amounts and types of data that are to be submitted.

The summary is a tabular list of the types of samples being submitted, the analyses performed (see
Section 2.7), and the EDD file types (see Section 3). Table 2-1 presents an example summary and
the template, 'Data Submittal Summary Template (.XLS)', may be downloaded from:

http://www.epa.gov/superfund/region-4-superfund-electronic-data-submission

Fund lead projects going through the R4LIMS system will receive an email with the summary.
When you do not receive an email with a Project Log Summary Report, then prepare the summary
according to the data requirements outlined in your QAPP.

See Table 2-2 for an explanation of when this should be submitted, depending on your submittal
type. The email containing Project Log Summary Report serves as the Data Submittal Summary.
The data provider completes the file, indicating the data that will be submitted when ready, and E-
mails the file to: R4DART@epa.gov.

The format of the file is shown below (the actual file may have too many columns to display on the
printed page):

2.2 File Formats

All data to be reported to EPA Region 4 must be submitted as signed ".edd" files generated by
importing EDD files to EDP (Sect. 2.11) and exporting for submission. EDD files can be produced
using any software with the capability to create text files but these files must be checked with the
EDP (Sect. 2.11) prior to submittal to EPA Region 4. These files are especially easy to create using
spreadsheet or database software packages. However, if these are unavailable, the files can be created
using a word processor or text editor. Table 2-3 provides instructions for creating tab-delimited text
files from some widely-used software packages.

Instructions

EQuIS

Database

Data already existing in an EQuIS Database of any version must still be
exported to the various EDD files and checked with the EDP. Export
individual tables into a spreadsheet format so that they may be reformatted
into the correct data structure described in Section 3. Then follow the
instructions from "Excel" below for exporting to the text file format.

2.3 EDD Files

The tables in this guidance identify the various types of data being requested. Each EDD file should
be saved as an individual text file and should be named in accordance with the naming convention
rules. Table 2-4 provides general information on the files that make up this EDD. Detailed
instructions for creating all the EDD files are provided in Section 3. Instructions for submitting your
EDDs to EPA Region 4 are presented in Section 4.0 and in the EDP Reference Manual. Figure 2-1
below shows the EDD creation process conceptually.

It is not possible to prepare a dataset for acceptance into a database without understanding the basics
of how databases operate. Row uniqueness and referential integrity are requirements of the EQuIS
database. Their requirements impact how the EDD is prepared.

Row uniqueness is assured when no two rows in a file contain the same values for all the fields listed
under the heading "What makes a row of data unique?" in Table 2-4, also see Section 2.4.

USEPA Region 4 Format Guide

The relationship between rows within the files of the EDD must be assured by enforcing the
"referential integrity" rules discussed in Table 2-4 under the column labeled "Dependence of other
files on these data", also see Section 2.4.

2.4 Data I ntecfity Rules

Data providers are responsible for performing three types of integrity checks on their data prior to
submittal.

Validity. All codes used in a data set must be valid. Valid values for all coded fields are either
provided in the description columns of the tables in Section 3 or in the reference tables of the EDP.
Data providers must use the most up-to-date reference tables (.rvf files) available from EarthSoft. For
example, sample matrix information is input in the samplematrixcode field of the Field Sample
Results table and must be reported using one of the values provided in the reference file associated
with EDP. It is essential to obtain the latest version of the formats and reference files before
beginning work.

Row Uniqueness. Row uniqueness must be verified using the guidance provided in Table 2-2. In
database terminology this is called a primary key. For example, the sys loc code is the primary key
in the Location EDD table and therefore no two rows in the file can have the same sys loc code
value. The EDP will highlight duplicate rows of data to assist you in locating these errors.

USEPA Region 4 Format Guide
Version 1.20 December 2015

10


-------
Row Integrity . The relationship between rows within the tables of the EDD must be assured by
enforcing the "referential integrity" rules discussed in Table 2-2 under the column labeled
"Dependence of other files on these data." For example, the values in the sys loc code field in the
Field Sample Results table must match with a value previously reported in the sys loc code field of
the Location table. The EDP will not test for integrity between EDDs and existing data in the
database until it is loaded. The data provider will be responsible for taking care not to submit
duplicate data. If the data fails integrity tests, it will NOT be uploaded into the DART system at EPA
Region 4 and you will be notified via automated E-mail that the data was not successfully loaded.
You will need to correct any errors and resubmit the data along with the error report E-mail.
Instructions are included with the E-mail.

2.5 File Naming Convention

The data submittal is actually a .zip archive file containing one or more of the individual EDD files
(see Section 3).

The submitted file IS REQUIRED to be named according to the following convention after
processing with the EDP:

Lab Project NumberLab Project NameData ProviderYY MM DD_Type.EPAID.EPAR4.edd

Note:

Lab Project Number is provided by EPA Region 4.

Lab Project Name is provided by EPA Region 4.

Data Provider is provided by EPA Region 4
EPA ID is provided by EPA Region 4

The .edd file is a standard .zip file. The extension must be changed to .edd or the file will be rejected
by the USEPA E-mail server. EDP has an option to save the EDD with the .edd extension.

As an example:

P2015-0001_ChemicalCompanyABC_PL-DataProvider_15 01 08_Ch.l 10001224773,EPAR4.edd

•	Task Code is P2015-001,

•	Site Name is Chemical Company ABC,

•	Company Code is PL-DataProvider,

•	Date Submitting is January 8th, 2015 as 15 01 08,

•	Type of data submission is Ch for Chemistry,

•	Facility Code is 110001224773, and the

•	Format used is EPAR4

This filename is in the E-mail you received when the proj ect was created at EPA Region 4 - you can
copy and paste to rename your .edd file.

NOTE: In order for EPA Region 4 to properly process the EDDs, the file naming convention must be

USEPA Region 4 Format Guide
Version 1.20 December 2015

-------
followed or the EDD will be sent back to the data provider for correction.

2.6 Valid Values

Valid values, also known as reference values or code lists, govern the contents of some fields in the
EDD files and create some of the drop-down menus in EDP. In other words, some fields may only
be populated with data that matches a value listed in the EPA Region 4 list of valid values in EDP
exactly. A list of all the data fields that must contain valid values is presented in Table 2-5. This list
is also cross-referenced to the EDD file(s) in which the field appears.

If data providers need to enter a value not already in the EPA Region 4 Valid Value List, they can
request the proposed addition to the valid value list by sending an E-mail to R4DART@epa.gov.
The data provider should explicitly state the valid value that she/he would like added, into what
reference table the value needs to be added, provide a description of the value, and explain why
the addition is necessary. In the case of requesting a new laboratory code, the data provider
should include the full name of the laboratory and its address and contact information. When
requesting an addition of an analyte, the data provider must include the appropriate CAS RN or
EPA ID along with a description of the analyte. The EPA SRS

(http://iaspub.epa.gov/sor internet/registry/substreg/home/overview/home.do) should be
thoroughly examined for an existing CAS RN before submitting a request for the addition of new
analytes. Select the "Search & Retrieve" tab and enter the CAS Number, Chemical name or other
identifier. Be certain to check for synonyms. This will minimize possible confusion with
conflicting numbers and small variations in chemical naming conventions. EQuIS relies on the
CAS RN as the primary key, not the chemical name.

2.7 Understanding Analytical Methods

Analytical Methods pose a special challenge in dealing with data from multiple sources and time
frames within a single database environment and must be handled with care to provide the most
accurate information possible. The EPA Region 4 valid value table, included with the reference files,
contains analytical methods based on the EPA laboratory nomenclature.

EPA Method CoderLab Analytical Code i.e., VOArEPA 8260B

In the example above," VOA" refers to volatile organic compounds while "EPA 8260B" refers to the
laboratory analytical method of discovery of volatile organic compounds by gas
chromatography/mass spectrometry (GC/MS). When formatting your own data to comply with the
standards necessary for input into the EPA Region 4 EQuIS System, it is important to ensure the
methods used in identifying your data fit properly into one of these standard methods. Table 2-6
below provides a list of EPA Method Codes.

For "Historical" data, if the analytical method is not known, the data may be reported using only the
appropriate "Method Code" from Table 2-6. For all "Current" data, the Method Code and Lab
Analytical Code are required.

2.8 Reporting Results

Laboratory results (both Detects and Non-detects) must be reported as shown in the example below.
Each non-detect row must show an "N" in the detect flag field and must have values entered in the
quantitationlimit and detectionlimitunit fields (i.e., these fields cannot be left null. If no
quantitation limit is available for historic data, but a result value is available, a qualifier of "X"
should be added to the interpreted qualifiers column and a value of -999999 should be added to the
quantitation limit column. Table 2-7 presents an example of how to report a detect (1st row) and
non-detect (2nd row) data. Results with a text value, such as "NA," "ND," or other non-numeric
values should not be reported, as noted in the last row of Table 2-7.

2.9 Reporting Duplicate Lab Results

"Laboratory Duplicates" can occur for a variety of reasons including dilutions, equipment tolerances,
sample conditions, and holding time allowances. Results should be validated and only the final result
may be submitted to EPA Region 4. When duplicate results are reported from the lab and
determined by your RPM to report BOTH results, the Test Type specified in the EDD needs to
identify accurately the type of result. An example of how to report laboratory duplicates is presented
in Table 2-8 below.

2.10 Reporting Tentatively Identified Compounds(TICs)

Tentatively Identified Compounds (TICs) present an additional challenge in reporting to a single
database as there is no standardized method of reporting from one source to another. TICs should be
reported when the following conditions are satisfied:

1) The compound is accompanied in the lab report by a valid CAS RN (or EPA ID) and

USEPA Region 4 Format Guide
Version 1.20 December 2015


-------
chemical name. Validity should be checked with EPA SRS.

2)	The quantitationlimit is present.

3)	A valid labanalyticalmethod was used and reported.

When reporting TICs that meet these conditions, the resulttypecode in the Result EDD must be set
to "TIC". Table 2-9 demonstrates the proper method for reporting this result data along with standard
data.

All ancillary information associated with reporting TRG chemical results should also accompany
TICs. These include sys sample code, labanlmethodname, analysis date, analysis time, cas rn,
chemicalname, result type code, quantitation limit, result unit, detectionlimitunit, and
testbatchid.

2.11 Using the EQulS Data Processor to Check EDD Formatting

All EDD files must be processed with the EQulS Data Processor (EDP) prior to submittal to EPA
Region 4. The EDP is a no-cost application that performs a series of formatting checks on EDD files
and then identifies any records that have errors, along with a description of those errors. This allows
the data provider to correct the errors before sending the files to EPA Region 4. EDD files that pass
through the EDP error-free should also result in error-free import at EPA Region 4.

The EDP, EPA Region 4 Format File, and EPA Region 4 Reference Values Files (.rvf) are
available as no-cost downloads from the EarthSoft website located at

http://earthsoft.com/produrisfedp/edp-format-for-epar4/

Instructions on how to install and use the EDP are also provided on the website and in the Region 4
EDP Reference Manual. You will need to register the EPA Region 4 Format with EarthSoft in order
to use EDP. Follow the instructions provided with EDP for registering properly. Contact R4DART
for the required authorization code to enter during registration. You will not be able to use EDP with
the correct EPA Region 4 Format without proper registration.

Once you have installed and licensed EDP, you should use this document as a guideline for
formatting your data to conform to the necessary EDD formats. Load the EPA Region 4 Format and
reference tables into EDP per the instructions in the Region 4 EDP Reference Manual. Import your
individual EDDs to the correct section (i.e. Geology, Chemistry. Or Basic Field Results) and test
your data for readiness to import.

USEPA Region 4 Format Guide
Version 1.20 December 2015

3.0 EDD FILE FORMATS

This section contains detailed information regarding the files that make up the EPA Region 4 EDD Format. As stated in section 2.1, each
EDD file must be saved as individual text files and can be created using any software with the capability to create text files (including
EDP). If a column is limited to a specific number of characters, the limit will be given in parenthesis within the "Data Type" column (e.g.,
"Text (3)" signifies the value cannot exceed 3 characters in length). Columns marked "Required" must be reported for each row in the file.
If these fields are not reported, errors will be identified in the EDD and the EDD will need to be resubmitted. Columns marked "If
available" should also be reported if possible.

The Location file needs to be submitted as part of the first EDD submittal. This file need only be submitted once, unless information in the
file changes or additional information, such as a new sampling location, needs to be added.

For all other EDD files, EPA Region 4 will send a list of the EDDs expected for the data submittal.

Note: EPA Region 4 will provide the valid values for data_provider, task code and activity code for each data submittal.

3.1 Site EDD File

The Site EDD file contains general information about the site, including EPA Region 4 data providers' contact information. The Site
EDD file is typically submitted only once for new sites and must be part of the first EDD submittal. The site file only needs to be
resubmitted if the site information needs to be updated, such as the site name or data provider information for the site. When
resubmitting the site file, please notify EPA Region 4 that the site information has changed and needs to be updated.

Site EDD files should be named according to the following convention: EPAR4_Site_vl.csv or .txt for tab-delimited files.

3.2 Location EDD File

The Location file is typically submitted only once and must be part of the first EDD submittal. The location file only needs to be
resubmitted if a new sampling location is used, such as a new monitoring well, or to update previously submitted information. When
resubmitting the location file, only include data for the new locations and/or for the locations whose information is being updated. The
Location EDD file contains general information about sampling station locations and station ID numbers. This table does not need to be
resubmitted if information has previously been submitted to EPA Region 4 as an EDD.

Location EDD files should be named according to the following convention: EPAR4_Location_vl.csv or .txt for tab-delimited files.

3.7 Chemistry Field Sample EDD File

The Chemistry Field Sample EDD is the crucial file by which all chemistry result data is based. Syssamplecode uniquely identifies each
sample that was returned from a laboratory with a result. This value is unique throughout the database, even for resamples, duplicates, etc.
This does not represent the value submitted on the chain of custody when sending samples to the lab for analyses (which should be
populated in the samplename column).

Chemistry Field Sample EDD files should be named according to the following convention: EPAR4_FSample_vl.csv or .txt for tab-
delimited files.

3.9 Chemistry Test EDD File

The Test EDD ties the Field EDD to the results by correlating the analytical method used with the sys sample code, along with the analysis
date and time. It is important to follow the guidelines for the EPA Region 4 sys sample code. The R4 prefix is reserved for SESD/CLP
LIMS (Element) data. Regardless of the sample's source, the sys sample code must match the Chemistry Field Sample section's
sys sample code to tie the tests back to the sample. Lab analytical methods should be matched to the valid values. Historical data should be
matched as closely as possible or an R4-HIST or HIST method should be chosen that matches. When these assumptions are made, they
should be listed in the technical documentation of the conversion. When no suitable analytical method can be found, the method should be
submitted to EPA Region 4 along with a description for review and possible inclusion in the valid values tables.

When preparing data from non-SESD/CLP labs, as well as historical data, certain required data such as the analysis date and time may be

USEPA Region 4 Format Guide	22

Version 1.20 December 2015


-------
missing. A convention has been created to handle these inconsistencies and enter data successfully into the EPA EQuIS system. When the
analysis date is not present in the lab report, it should be reported in the EDD using the same date as the sample date but with an analysis
time of 23:59. This will allow the user to easily identify data with missing analysis dates, and to recognize that information was missing.
Data results with an analysis date but no time should be given an analysis time of 23:59. It's important not to use arbitrary times that are
similar to other actual data times as these give the appearance that the data set was complete and not simply an estimate.

At any time there is estimated information populated you must include a comment describing what was added within the comment field.

3.15 Geolocpc Sample EDD File

The variations in geology nomenclature make the submittal of geologic data, particularly historic geologic data, a special challenge. The
Geology Sample EDD is the first of several EDDs used to capture as much geologic data in a useable form as possible. The Geologic
Sample Parameter, and Static Properties EDDs rely on information populated in the Geologic Sample EDD. Other files, related to geology
are correlated to the Geologic Sample EDD via the sys loc code for the boring. This EDD links locations with geologic samples, tasks, and
activity codes.

Geologic Sample EDD files should be named according to the following convention: EPAR4_GeologicSample_vl.csv or .txt for tab-

3.32 FilesEDD Section

The Filesvl table of the EPA Region 4 Format allows maps, figures, and published layer types of files to be loaded into the EPA Region 4
database. When completing a data submission using EDP Sign and Submit, the files entered into the Files vl table's file name field will be
packaged within the EDD.

Site base maps can be submitted as CAD files in a DXF interchange format, drawing (.dwg) file, or Shape files (.shp) generated from
ArcGIS. The maps should include all well locations, waste management units, property boundary, landfills, buildings, and roads. Do
not include any groundwater contours, contaminant contours, or other temporal type information. If the CAD file is available in real
world locational coordinates, provide the coordinates along with a brief text description of the type of projection and datum used.

(Note: Lat Long as WGS 84 in decimal degrees is required by EPA Region 4). Also include text descriptions of the units and scale of
the base map. The site base map file should be named according to the following convention:

TaskCode.SiteName.CompanyCode.SubmissionDate.FacilityCode.DXF (or dwg, or shp)
