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.

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 Draft FY 2022-2026 Strategic Plan (Draft Plan). Applicants are encouraged to read the full text of the Draft Plan at: 
https://www.epa.gov/system/files/documents/2021-10/fy-2022-2026-epa-draft-strategic-plan.pdf. 

EPA expects to award 20-30 grants of up to $400,000 each, totaling approximately $8,000,000 in FY22. Most awards will be in the $50,000 to $200,000 range. The exact number of grants will depend on the number of applications submitted to EPA by the application deadline, the amounts of proposed project budgets, and the quality of proposals. 

EPA only accepts project proposals for EN grants submitted electronically through Grants.gov, unless applicants have a waiver. Please allow for enough time to successfully submit your application and allow for unexpected errors requiring you to resubmit. EPA anticipates that it will announce selection decisions around August 2022, and tentatively plans to issue awards by October 2022.

Over the weekend of July 23rd, the U.S. EPA’s Central Data Exchange (CDX) core services migrated to a new database platform. Beginning the morning of July 26th, performance issues began manifesting for some users when interacting with the CDX Next Generation Node (NGN), Exchange Network Services Center (ENSC), and Exchange Network Discovery Service (ENDS). Initial tuning attempts provided limited relief. On the evening of Wednesday, July 28th configuration changes were made to alleviate the widespread performance issues.

As of the evening of August 2nd, there are no known widespread performance issues impacting Exchange Network services, and the situation continues to be actively monitored.

In the coming weeks, U.S. EPA will be migrating Shared CROMERR Services (SCS) to a new hosting environment. The migration, which will include SCS SOAP, REST, and advanced portal services, will take place on the following dates:

• May 14, 2021 – Dev and Test Environment
• June 4, 2021 – Production Environment 

Details

No SCS services endpoints will change after the migration. All endpoints will remain as follows:

• Dev endpoint – https://encromerrdev.epacdxnode.net
• Test endpoint – https://encromerrtest.epacdxnode.net
• Production endpoint – https://encromerr.epa.gov

All IP addresses WILL change after the migration.

IMPORTANT: IP ADDRESS CHANGES MAY REQUIRE PARTNERS TO ADJUST FIREWALL RULES TO ACCESS SCS SERVICES.

The new IP addresses will be:

• DEV: 40.71.227.82
• TEST: 204.47.254.135
• PROD: 204.47.254.197

U.S. EPA recommends testing SCS services in each of the respective environments based on the dates above to ensure no firewall changes are required.
