{ "registration": "08-0169", "filer_name": "PLAINS PIPELINE", "grain": "system_grain", "grain_reason": "PLAINS PIPELINE 08-0169, filed against the BASIN edge and refused for it -- AND THE STATED BLOCKER ON THAT REFUSAL HAS BEEN LIFTED, so this is a decided no rather than a deferral. config/t1_edge_coverage.yaml recorded Basin as undecidable while counterparties 'MSP' and 'J2M' were undecoded registrations; the 2026-08-11 header fix decoded both, they were read on 2026-08-19, and the answer is that they make the aggregate case STRONGER. 08-0892 'MSP' is Midland Station, a HUB: it receives 311.9 MMBBL from Basin and delivers onward to Cactus II (159.1), McCamey, PMT, BridgeTex and Mesa, spanning districts 03, 06, 08 and 8A. 08-1072 'J2M' is a clean single-district line delivering 479.5 MMBBL INTO Basin. So 476.3 + 264.6 MMBBL of what this filing certifies is Plains handing barrels between its own registrations. The arithmetic settles it without them: 1,696.6 MMBBL over 12 months of 2025 = 4,648 MBBL/D against Basin's 450 nameplate, 10.3x -- and the largest SINGLE row is still 2.9x. 42 facilities over 6 districts (03, 7B, 08, 8A, 09, 10) -- RESTATED 2026-09-07, from 35 over 3 (08, 09, 8A), when the five 2026 filings landed. The ruling gets STRONGER rather than moving: the same certificate now spans twice the districts. Note the arithmetic above is a 2025 measurement and these counts are corpus-wide, so the two must not be read as one number. THE LEAD THIS REASON RECORDED WAS TAKEN UP: one slice of the filing is wired as Basin (T1_CORRIDOR_SLICE, approved by HQ 2026-10-19) -- 'EXPORTS TO OKLAHOMA' plus the Wichita Falls deliveries, less the Wichita Falls receipts. It needed a second witness rather than a better ratio, and got one: Sunrise II 08-4518 files its OWN export row and books its Wichita Falls handoff into Basin to the barrel in every month both are held, so Basin's export row is not Sunrise's.
