Company overview
Premcor Refining Group Inc. operates as a refining concern whose history in the petroleum sector ties it to SIC 2911, blending legacy service offerings with the petrochemical realities of crude distillation, asphalt, and fuel production; it supplies national wholesalers, fuel distributors, and regional transportation fleets that rely on its complex operations to deliver transportation fuels and intermediate feedstocks, and it positions those capabilities against a marketplace shaped by regulatory oversight from the EPA and DOT plus state-level environmental compliance, all of which heighten the material risk of tightening emissions limits, refinery outage recovery plans, and feedstock price volatility; while the company no longer trades under a ticker, interested parties can monitor its disclosure status and any future form submissions—Latest filing status: unknown—through the live SEC filings feed on Earnings Feed.
