Where this facility sits in the TRI record

Among the 902 Petroleum facilities in this database, Valero Refining-Texas LP Corpus Christi West Plant reports the 24th-largest volume, placing it in the top 2.7% of its sector.

Placement is computed from reported TRI pounds in this database. Thresholds are fixed across every facility page: concentrated ≥60% of volume in one chemical, county-dominant ≥25% of the county total, carcinogen-heavy ≥50% of pounds. Share-based statements are shown only for sites reporting at least 1,000 lbs, because a share of a very small total is not a meaningful signal. Reported pounds are self-reported estimates and do not measure toxicity or health risk.
