Did Any PVC Plant Ever Meet 0.018?
EPA switched off a PVC process wastewater limit on Monday, six years to the day after proposing to, and the number it nullified was 6,100 times tighter than the one every operating plant has to meet. Also new since Saturday: six paraquat registrations go back to the agency, SunCoke drops a patent from its foundry coke exclusion case, and the Koppers plant this desk called new has had a WARN notice on file since February.
There is a number in the federal PVC air rule that has sat on the books since 2012 and has never bound a single plant.
It is 0.018 parts per million by weight. On Monday morning EPA switched it off.
"What is a MACT floor worth when no source was ever subject to it?"
Everything below is new since Saturday's radar. Monday's Federal Register did most of the work, and this desk owes you a correction on a plant we called new.
Fourteen Years, and Then a Footnote
The rule is 91 FR 70796, docket EPA-HQ-OAR-2002-0037, effective the day it published.
For new major sources in the PVC and Copolymer Production category, EPA removed the total non-vinyl chloride organic HAP process wastewater limit and its testing, monitoring, recordkeeping and reporting, and finalised vinyl chloride as the surrogate for the rest of the stream.
The number stays printed in the table. A new footnote says it does not apply.
