The purpose of the Exchange Network (EN) grant program is to foster better environmental management and decision-making through increased access to timely, high quality, environmental information. An applicant’s proposed project goals and outputs should align with one or more EN Funding Areas as described in Section I-B of the SN and EPA’s FY 2022-2026 Strategic Plan. Applicants are encouraged to read the full text of the EPA Strategic Plan at:  https://www.epa.gov/planandbudget/strategicplan.

The World Wide Web Consortium (W3C) recently conducted tests in August and September that impacted some agencies that use U.S. EPA’s Shared CROMERR Services (SCS). During these tests, the W3C redirected all internet traffic to its website to use the HTTPS protocol. While those tests have concluded for the time being, W3C indicates that it will eventually implement the change on a permanent basis. For additional information on the W3C’s recent testing, you may read entries in their blog here and here.
 
How does this impact users of SCS?
 
Some partner agencies experienced difficulties connecting to SCS during the W3C’s recent testing. This is because the Web Service Descriptor Language (WSDL) files for SCS include references to resources that are hosted on the W3C website. These references use the HTTP protocol instead of HTTPS. As a result, connectivity to SCS was interrupted for some agencies when the W3C redirected traffic to use HTTPS.
 
How will this issue be remedied?
 
U.S. EPA has revised the SCS WSDL files to use the HTTPS protocol. Testing indicates that this change resolves the connectivity issues with SCS. The updated WSDL files are available now in the SCS DEVELOPMENT and TEST environments (please see the URLs below). EPA plans to also deploy the changes to the SCS PRODUCTION environment on the evening of October 21, 2022.

Does this issue impact any other services or the Exchange Network?
 
At this time, there is no indication that other services or the Exchange Network will be impacted. EPA and its partners will continue to monitor and test for possible impacts. If your agency experiences any issues or has questions, please contact the Exchange Network Help Desk to report the problem.

Partners from the Exchange Network community are invited to provide comments on a set of draft best practices documents produced by the Interstate Technology and Regulatory Council (ITRC). ITRC is a state-led coalition working to reduce barriers to the use of innovative air, water, waste, and remediation environmental technologies and processes. ITRC produces documents and training that broaden and deepen technical knowledge and expedite quality regulatory decision making while protecting human health and the environment.
 
The ITRC Environmental Data Management (EDM) Best Practices Team was formed in early 2021 to address the need for integration and cohesion of data management across environmental disciplines and programs in states, tribes and industry. The team has been hard at work for over a year producing a set of documents and tutorials that focus on the fundamentals of environmental data management. Topic areas included in the team’s work products include:

• Data Exchange
• Data Management Planning
• Data Quality
• Environmental Data Management Systems
• Field Data Collection
• Geospatial Data
• Public Communications and Data Accessibility
• Traditional Ecological Knowledge (TEK)

The team is now requesting External Review of their work products and the reviews are due to the team by COB of July 1, 2022. They welcome any and all comments, whether it is to review the entire set of documents or focus on specific area(s) of interest and expertise. The team also appreciates any additional outreach to other interested parties through your professional affiliations and contacts as you deem appropriate. Feel free to spread the word!
 
The documents are available at https://connect.itrcweb.org/viewdocument/itrc-edm-best-practices-work-produc.Detailed instructions are provided at the beginning of the PDF draft document bundle.
 
Please send comments to: Team Leaders (Douglas Morrison and Brian Pointer) and Program Advisor (Steve Brauner). Thank you in advance for your attention to this request.

U.S. EPA’s Central Data Exchange (CDX) will be performing some planned system maintenance on Friday, June 3, 2022 between 7:00 PM –  9:00 PM Eastern time. During that window, users of the Exchange Network, CDX Web, and Shared CROMERR Services may experience intermittent outages.

The U.S. EPA Central Data Exchange (CDX) plans to perform system migrations on several Exchange Network services in the coming weeks. These migrations will happen first in the TEST environment and then in the PRODUCTION environment. The planned dates for these migrations are:

• TEST – Friday, September 24, 2021, 5:00 PM ET to Monday, September 27, 2021, 8:00 AM ET.
• PRODUCTION – Friday, October 15, 2021, 5:00 PM ET to Monday, October 18, 2021, 8:00 AM ET.

 
What will be the Impact to Partner Agencies?
During these planned migration windows, users of the Exchange Network and CDX Web services listed below will experience outages. Please plan accordingly and schedule any transactions outside of these windows. As part of this migration, some services will be assigned new IP addresses. IMPORTANT: Partner agencies with strict firewall rules may need to adjust those rules to allow traffic from the new IP addresses in order to continue accessing the services. Please see below for the new IP addresses for each service in the TEST and PRODUCTION environments.
