Rule Summary

The 1987 Standards of Performance for Volatile Organic Liquid Storage Vessels (including Petroleum Liquid Storage Vessels) for which Construction, Reconstruction, or Modification Commenced after July 23, 1984, is applicable to large storage vessels, which store volatile organic liquids across a variety of industries, such as petroleum refineries, chemical plants and portions of the oil and gas industry.

Since 2018, EPA has received a significant uptick in the number of owners or operators requesting alternatives to conducting out-of-service inspections of storage vessels subject to the 1987 NSPS.  EPA is proposing to reduce the burden on industry by making “in-service” inspections of certain large storage vessels filled with liquids (particularly crude and petroleum products) more widely available under Clean Air Act regulations.
