Why Mesothelioma Cases Occur in Big Spring
Cosden Oil & Chemical opened the Big Spring refinery in 1929, making it one of the oldest continuously operating refineries in West Texas. Through ownership changes — Fina in later decades, then Alon USA, then Delek US — the refinery has operated nearly a century. Cosden's historic asbestos use in crude distillation units, reformers, catalytic crackers, heat exchangers, boilers, and pipe systems is documented in federal court cases and Big Spring Herald historical archives.
The Alon USA / Delek Big Spring Refinery continues today as one of Delek US Holdings' four refineries. Over its 95-year history, three generations of Howard County workers have passed through the Big Spring refinery gates. Asbestos insulation, pipe lagging, gaskets, and packing materials were standard in every process unit through the early 1980s, when federal regulations curtailed new asbestos installations in refineries.
Coburn Supply Company oilfield equipment yard and other Big Spring oilfield-services operations serviced the Permian Basin's production infrastructure. Oilfield service workers handling pumps, compressors, wellhead equipment, and downhole tools encountered asbestos-lined gaskets, packing, and brake materials routinely through the 1980s.
The broader Howard County industrial base also included historic cotton gins, rail maintenance facilities (Big Spring sits on the historic Texas & Pacific Railroad mainline), and power generation serving the Permian Basin. All of these operations used asbestos-containing materials during the peak-use era from the 1940s through the early 1980s.
The 20-to-50-Year Latency Period
Mesothelioma does not appear immediately after asbestos exposure. The disease has a latency period of 20 to 50 years, meaning workers exposed in Big Spring-area facilities during the 1950s, 1960s, and 1970s are being diagnosed now. A tradesperson who worked around asbestos insulation in Big Spring in 1970 may only receive a mesothelioma diagnosis in 2026 or later. This long latency period is why Big Spring continues to produce new mesothelioma cases decades after asbestos use was curtailed.
Big Spring's Asbestos Legacy by the Numbers
The Big Spring refinery has operated continuously since 1929 — 95-plus years of refining operations under successive owners (Cosden, Fina, Alon, Delek). Three generations of Howard County workers have been employed there. Texas allows 2 years from diagnosis to file a mesothelioma claim.
