O , * EPA Region 4 EQulS Data Providers i$gSZ.5 Summary of Monthly Meetings The Superfund Program in EPA Region 4 uses EQulS 7 Enterprise to manage to their environmental sampling data. The EPA Region 4 holds a monthly meeting for data providers on the third Tuesday of each month at 11:00 am ET. This document is intended to capture the main points of each meeting as well as any changes and updates since the prior meeting., this document will be replaced with the most recent month's information as the top-most entry. If you have found this document and are a data provider that has not been invited to the monthly call, please email R4DART(Sepa.gov to be added to the meeting. April 2020 Meeting Announcements 1. Reminders a. Be sure to have your GIS map files delivered via the GIS Data Submission Form. i. The form may be accessed at https://arcg.is/laDXva. ii. We still have only received 1 set of map files to begin dashboard development! b. Be sure to send your EPAR4_POC EDD to epar4(a)equisonline.com ASAP! i. We have only received 23 POC EDDs from 12 companies as of April 27, 2020. c. When sending in your EDDs, you will receive 2 automated emails back. The first one is to let you know the EDD has passed the EPAR4 Enterprise system's EDP (or you had an issue with the facility code not found email). The second email will either have a commit log with the number of rows added or an error log attached. i. Recent rejected EDDs have resulted in some uncommon scenarios. • A space before the facility code but after the first period. A space is a valid character. Be sure there are no extra characters between the periods so the system may parse the parts to know what facility to load to and which format to check the EDD against. • The same file name sent with different data. If the second file name is received by the system before it processed the first file, the system will add an _1 to the file name. This creates an invalid file name and will not process the second file. ii. The file name convention: 13-0001_YourSite_YourCompanyCode_19 0108_Ch.ll0001224773.EPAR4.dat 2. Updates a. We have EPAR4 folks that are unable to use the data for certain analysis due to data gaps. • For wells, we need either the dtjocation's total_depth or the dt_well's depth_of_well. Without the depth, we are unable to get a rendering of the wells using EQulS Envirolnsite. • For fish data, we need minimally the fish length and weight. b. The EarthSoft developers are working with Athens Field personnel to create an EQulS Collect Vapor Intrusion (VI) collection form. A demonstration of the progress was presented to Athens who provided feedback. EarthSoft will continue development and pilot with Athens before this is available to contractors. c. The VI section of the EPAR4 format will be replaced over the next month to ensure consistency with the VI Collect Form field collection. Additionally, a new EPAR4.rvff\\e has been provided with new values specific to VI.

EPA Region 4 SEMD Data Providers Summary of Monthly Meetings April 2020 2 ------- January 2020 Meeting Announcements 1. Reminders a. Be sure to send your EPAR4_POC EDD to epar4@equisonline.com ASAP! i. We have only received 9 POC EDDs from 8 companies as of January 17, 2020. ii. But 16 other companies have submitted data that still do NOT have a POC EDD sent in. 1. If you send an EDD and do NOT receive an email back - something went wrong. 2. Email R4DART to assist with investigating why the EDD did not process. b. You should receive 2 emails back when you submit your EDDs to EPAR4@equisonline.com. c. Send in your location EDDs in a reasonable timeframe. You receive an email with a due date but there are still folks not sending them in and the analytical EDDs continue to be rejected! 2. At the end of the call, we will have a "Demonstration of the Required GIS Data Submittal Process". 3. Previously Katie Wise's email was provided incorrectly, it is Wise.Mary@epa.gov but you will still submit the map files to EPAR4DARTGeo@EPA.GOV 4. When the EPAR4 laboratory sends out EDDs with an "UPDATED: R4 LIMS Results..." in the subject line: a. Please review the PDF attached within the file set for why it was updated. b. R4DART only knows to add the Update tail to the EDD before emailing to the system. c. If anything needs removed from the original submission, you must notify R4DART immediately. d. An update will not remove data - there is a special process to remove data called "Rollback". e. This is also true if you send in an EDD and realize you shouldn't have added it. 5. The Environmental Data Submission Procedure (SEMDPROC-009-R0) and Guidance have been finalized. a. https://www.epa.gov/superfund/region-4-superfund-electronic-data-submission is pending update. b. The three supporting reference documents are provided with the procedure as one .pdf • EPA Region 4 EDD Format File Guide - Provides detailed information for the creation of the EDD files that are required to be submitted. • EPA Region 4 EQulS Data Processor (EDP) Reference Manual - Provides the information needed to download, install and maintain the EDP software, as well as how to use the software to proof EDDs and create data packages. • EPA Region 4 Geographic Information System Deliverable Guidance - Provides specific requirements and file delivery formats for all GIS materials developed in support of the program. 6. Over the past month, there have been several EDDs rejected to R4DART as 'File Monitor Alert'. a. You will not receive these emails due to the system's inability to decipher the file name. b. These rejections are due to extra periods in the file name so the system cannot parse the pieces. • "EPAR4 Guidance Defined Section", "facility code", "format".dat • The system uses the periods to split the file name to know which facility and which format. c. Causes of too many periods may be: • When you send one email with two files of the exact same name, the email system will add .1 • Using periods rather than underscores between the portions of the "EPAR4 Guidance Defined Section". 7. The EPA November 2019 Risk Screening Levels (RSLs) have been loaded to the R4DART system. a. Action Level report widgets have been added to the Site detail dashboard. b. There is a special note for 4 of the 2019 RSLs: • 2019 11 RSL IND AIR HQ=0.1 - "c ** High Risk used (0.021); Low Risk is 0.12 And Lowest Risk is 0.61" EPA Region 4 SEMD Data Providers Summary of Monthly Meetings April 2020 3 ------- • 2019 11 RSL RES AIR HQ=0.1 - "c ** High Risk used (0.0049); Low Risk is 0.028 And Lowest Risk is 0.14" • 2019 11 RSL IND AIR HQ=1.0 - "c ** High Risk used (0.021); Low Risk is 0.12 And Lowest Risk is 0.61" • 2019 11 RSL RES AIR HQ=1.0 - "c ** High Risk used (0.0049); Low Risk is 0.028 And Lowest Risk is 0.14" Contaminant Screening Levels Resident Air Industrial Air Analyte CAS No. (ug/m3) key (ug/m3) key -Polychlorinated Biphenyls (high risk) 1336-36-3 4.9E-03 c 2.1E-02 c ~Polychlorinated Biphenyls (low risk) 1336-36-3 2.8E-02 c 1.2E-01 c ~Polychlorinated Biphenyls (lowest risk) 1336-36-3 1.4E-01 c 6.1E-01 c c.

Sincerely Beth Walden, Sharon Keenan, and Katie Wise EPA Region 4 SEMD Data Providers Summary of Monthly Meetings April 2020 4 ------- November 2019 Meeting Announcements 1. Reminders a. Be sure to send your EPAR4_POC EDD to epar4@equisonline.com ASAP! i. We have only received POC EDDs from 6 companies as of November 18, 2019. ii. Reasoning for why we need your POC EDD: 1. EPA needs to have a quick means to query for the POCs. 2. EPA may have a question regarding data, map files submissions, EDDs, etc. 3. We have approximately 67 contractors with over 1000 sites (so a good memory no longer suffices). 4. Example scenarios: 5. Lab Procurement needs to know who the project lead is for assignment distribution. 6. EPAR4 GIS SME needs to find who was to submit a site's latest report map files. iii. Submit a POC EDD for each site for which you have a contract. 7. If all POCs are the same for every project within a site, use the 'ALL' Project ID. 8. If all POCs are the same for every site under your contract, email R4DART with your list of sites. iv. How to submit a POC EDD when you do not have a site assignment yet: b. Project ID of 'ALL' c. Facility code of'R4EQUIS' d. Site name of 'R4EQulS Facility' e. Company Code - If you have a code assigned, use it. Otherwise: PL-yourcompany (e.g., as there is no EarthSoft company code yet, EarthSoft would use PL-EarthSoft; where the company name is what is in your email address). f. Do not include a usr file unless you have a Region 4 user code existing. Use the quick start guide to establish a user code. If you do not have a site assigned, you will be given permission to the R4EQulS facility. b. After sending any EDDs to epar4@equisonline.com. you should make certain you ultimately receive the email "Successfully loaded EDD [file name]" with the commit log showing number of rows added. c. Do NOT linger to get your Location EDDs submitted. You typically receive an email requesting the location and field data prior to the release of the Analytical. i. Subject: (20-nnnn) Location and FieldResults EDD Request for Site Name: Due Date mm/dd/yyyy ii. When the location EDD is not submitted prior, the analytical data will be rejected. iii. The RPM will be notified when data continues to be stalled due to lack of submissions. 2. There has been a new mailbox setup for the map files to be submitted. a. We will be updating the documentation accordingly to send to R4DARTGeo@EPA.gov b. Katie Wise, Subject Matter Expert (SME), may be contacted at Wise.Mary@EPA.gov 3. The Data Provider Facility Specific Dashboard has been updated. a. Once you have a site assigned, it is common to want to see the existing data. i. Analytical Results Report - Make no selections to get all the Analytical data. ii. Location and Well Information - Produces the data in the EPAR4 format layout. iii. Download Water Levels - Uses the default of TOC to calculate the Walter Level Elevation. iv. Google Earth Locations - Produces a .kmz file to be opened with Google Earth. b. A brief demonstration of report selections will be held at the end of the call.

To display EQulS data on an ArcGIS Online layer, a token must first be established. a. The individual must have a valid EPAR4 user account and proper permissions. b. A video has been prepared on how to create the token: Download link: https://we.tl/t-XNEOGtleKP c. We anticipate having a demonstration of adding EQulS data to a map layer on our next call. 5. A new reference value file has been updated on the EPAR4 download site November 18, 2019. a. Please download the new .rvf from https://earthsoft.com/products/edp/edp-format-for-epar4/ b. What .rvf file will EDP use? i. EDP will use the EPAR4.rvff\\e that is within the EPAR4.zip format file first. ii. If not found, EDP will use the EPAR4.rvff\\e within the same folder as the format. iii. If not found, EDP will prompt you for what .rvf file to use. c. How to replace your existing EPAR4.rvff\\e for use by EDP i. The EPAR4.zip file found on the EPAR4 download site contains an old EPAR4.rvf. ii. Download the latest EPAR4_RVF.zip, extract it from the zip file, and copy it as EPAR4.rvf. iii. Replace the EPAR4.rvf existing within your EPAR4.zip format file. 1. You may drag the new EPAR4.rvff\\e onto the EPAR4.zip - It should prompt to replace. 2. You may extract the EPAR4.zip, replace the EPAR4.rvff\\e, and then rezip the EPAR4.zip file. October 2019 Meeting Announcements 1. Reminders a. Be sure to send your EPAR4_POC EDD to epar4@equisonline.com ASAP! b. Clarification: The file name within the POC dat file (zip) needs to be EPAR4_P0C.txt c.

EPA Region 4 SEMD Data Providers Summary of Monthly Meetings April 2020 7 ------- 2. The Point of Contact EDD template is now available. a. Obtain a copy from https://www.epa.gov/superfund/region-4-superfund-electronic-data-submission. b. Please read through your appropriate instructions tab before populating the EPAR4_P0C tab. i. Only one site's point of contacts per EDD. ii. Acquire your .usr file. iii. Save the EPAR4_P0C worksheet as a tab delimited text file with EPAR4_P0C.txt as the filename. iv. Zip the EPAR4_P0C.txt file with your .usr file. v. Rename your .zip file. The submitted file IS REQUIRED to be named according to the following convention. • Project ID (Task Code) • Site Name • Data Provider Company Code • Date Submitting (YYMMDD) • Type (POC) • .FacilityCode.EPAR4_POC.dat Example EDD Filename 19-0001_FacilityName_PL-DataProviderCode_190822_POC.110001224773.EPAR4_POC.dat vi. Email your .dat EDD to epar4@equisonline.com. c. When you have multiple Project IDs (task codes) for an individual site, you may submit a separate EDD or all in one EDD. Regardless, the Start Date must be different when you have multiple projects or people for the same POC type. (The facility, poc type, start date are the primary key fields.) 3. The EQulS R4DART system is set to automatically send the data provider emails when submitting EDDs directly to epar4@equisonline.com. a. You should receive the initial email with Subject "EDD File [file name] Status Update". This tells you that your .usr certificate was valid and you have proper permission to load to the EDD's target site. b. If your initial email after sending your EDD to epar4@equisonline.com has Subject "EDD File [file name] Rejected - Not a Valid Data Submitter for Facility", forward to R4DART@epa.gov to request your User Account is granted permission to the site. c. If no errors are found and the EDD is loaded, you should receive a second email with Subject "Successfully loaded EDD [file name]" with the commit log showing number of rows added. d. If errors are found and the EDD is NOT loaded, you should receive the second email with Subject "EDD File [file name] Rejected - Data Errors" with an error log attached. This error is typical of what you should see when you check the EDD with the current EDP EPAR4 format and reference values. If you did not get the errors when using the EDP, check the download site for a more recent reference file or an updated format. e. If errors are found and the EDD is NOT loaded, you may receive the second email with Subject "Failure while committing package [file name]" with an error log attached. This error during commit is typical when the locations' coordinates have not been loaded yet. f. If you do NOT receive any of the automated emails after sending your EDD: i. Check that your email system is not blocking emails from epar4@equisonline.com. ii. Try to login to https://epar4.equisonline.com with the credentials you used to create your .usr file. iii. Check that the file had the .dat extension. iv. Check that the file name only has 3 periods as this is how the system parses the name to determine what facility to load the data and what format to use for loading. EPA Region 4 SEMD Data Providers Summary of Monthly Meetings April 2020 8 ------- v. Otherwise, forward your submitted email with the file attached and note you did not receive any response from epar4@equisonline.com. 4. As an alternative to your Field Personnel using Scribe, an EDGE package has been placed on the EPAR4 download page. An EDGE Quick Start Guide is also pending addition to the EPAR4 electronic data submission page. 5. An updated EPAR4.rvff\\e has also been replaced on the EPAR4 download page. This includes new analytical methods and analytes from the Regional laboratory. Additional fish matrices have been added to more clearly identify their breed and part analyzed. 6. We would like to begin having some short demonstrations during this call. Please send in topics you feel may benefit yourself as well as others. August 2019 Meeting Announcements 1. The file name extensions have been updated. a. EDDs sent to epar4@equisonline.com need a .dat extension rather than an .edd extension. b. Error logs sent from EQulS Enterprise are .htm files and are no longer a zip file. 2. Lab EDDs use the data provider primary POC to add the user certificate. a.
