1. R18011 discussion
This document prepared for informational purposes only, and does not endorse a specific resolution to the request R18011.

2. R18011
Requests clarity regarding the columns in WEQ-004 Appendix D timing tables
Points out that approval windows may exceed the up to times in column B extra seconds from the distribution process completing in less than one minute

3. ActOnByTime being = 1 minute in column A + the time in column B
The Issue
These tables are implemented through the ActOnByTime in the Electronic Tagging Functional Specification
Specification states that ActOnByTime is set at the point of receipt by the Authority Service, ensuring the Approval Service has its up to time for approvals
Implementation of the standards through the specification utilizes a timer called “ActOnByTime” that is calculated by the Authority Service before distributing a request for assessment
The Authority Service does not know in advance how long it will take to distribute the request to each approval entity, and assumes it may take the entire 1 minute distribution window
ActOnByTime being = 1 minute in column A + the time in column B

4. WEQ 004 and Specification Process
WEQ Timing Table
Column A
Column B
WEQ 004 uses industry entity terms for responsible parties
Specification uses terms for roles in the system

5. Subcommittee Discussion
Five options evaluated
Set the assessment window based upon receipt of the approval entity
Set the ActOnByTime to exclude the one minute distribution window
Clarify the standards to reflect the current implementation, specifying that the any excess time from distribution window may be used by the Approval Service
Prevent approval or denial until the distribution window has elapsed
No changes and reject

6. 1. Independent Approval Windows
Complexity: High
Impact: implementations, specification and standards
Could result in delaying the approval if one entity receives the distribution later than one minute
Additional overhead to communicate each approval entity’s time
Subcommittee did not consider this an appropriate solution

7. 2. Assessment Window Incorporates Distribution Time
Complexity: Medium
Impact: implementation, specification and standards
Distribution time would be incorporated into the assessment window
Approval services never exceed the up to time in column B
Approval services receive less than their full approval time in column B, expected to be seconds
Subcommittee considers this a viable solution

8. 3. Clarify Standards Complexity: Low Impact: standards
Revise standards to clarify that excess time from the distribution window (column A) is added to column B
Approval Service’s assessment time could exceed the up to time in column B, expected to be seconds
Subcommittee considers this a viable solution

9. 4. Delay Approvals Complexity: Medium
Impact: implementation, specifications and standards
Requires the full one minute for distribution in column A before Approval Service may act
Results in an artificial assessment time
Subcommittee did not consider this an appropriate solution

10. 5. No Changes Complexity: none Impact: none
Consider the standards and specification to hold sufficient clarity that the industry requires for utilizing e-Tags and interchange
Would not clarify the question raised by the requestor
Subcommittee did not consider this an appropriate solution

11. Two viable solutions
Option 2: Assessment window incorporates the distribution time
No approval service will receive the full assessment window
Would result in faster processing by up to 59 seconds
Will alter all tag processing functionality
May need to address how INT is impacted
Option 3: Clarify the standards
Clarifies assessment may occur before the distribution window’s time expires
May be in the Approval Service processing queue more than column B time
Ensures that the Approval Service will have the full approval window
No changes to the current tag processing functionality

12. Example: Interchange Submitted <1 hour and ≥ 15 minutes prior to ramp start
Option 2:
Assessment window incorporates the distribution time.
Requires revisions to software, standards, and specification.
00:14
Option 3: Clarify the standards.
Requires clarification to WEQ 004 that the any extra time from distribution window will be provided to assessment window.

13. Next Steps Motion to adopt direction
Finalize recommendation for Executive Committee
Motion to submit for formal comments
