The Environmental Protection Agency (EPA) is proposing to approve revisions to the Indiana Administrative Code (IAC) rule entitled "Volatile Organic Liquid Storage Vessels" as part of Indiana's State Implementation Plan (SIP). This rule has been revised to: allow sources to use an alternative inspection method to demonstrate compliance, address an inconsistency in the language regarding the calculation of maximum true vapor pressure (MTVP), exempt sources complying with the National Emission Standards for Hazardous Air Pollutants (NESHAPS) requirements for storage tanks equipped with floating roofs, clarify language, update references, correct certain errors, and address standard language and style changes that have occurred over time since the rule was last revised.
The agency’s own summary, as published.
