Where this facility sits in the TRI record
Among the 902 Petroleum facilities in this database, Asphalt Inc Mix Mustang Ridge Plant reports the 614th-largest volume (2 lbs).
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.
