NSPS for Sulfuric Acid Plants (40 CFR Part 60, Subpart H) (Renewal)

The New Source Performance Standards (NSPS) for Sulfuric Acid Plants (40 CFR Part 60 Subpart H) apply to both existing facilities and new facilities. New facilities include those that commenced construction, modification or reconstruction after the date of proposal. A sulfuric acid plant is any facility producing sulfuric acid (H2SO4) by the contact process by burning elemental sulfur, alkylation acid, hydrogen sulfide, organic sulfides and mercaptans, or acid sludge. A sulfuric acid plant does not include facilities where conversion to sulfuric acid is used primarily as a means of preventing emissions to the atmosphere of sulfur dioxide (SO2) or other sulfur compounds. In general, all NSPS standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NSPS.

The latest form for NSPS for Sulfuric Acid Plants (40 CFR Part 60, Subpart H) (Renewal) expires 2026-07-31 and is listed under ICR 202108-2060-005.
