Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

The amendment to Rule 463 – Organic Liquid Storage, allows the determination of true vapor pressure fo r low

volatility petroleum products by using alternative test methods that rely upon other chemical properti es, including

flash point and percent volume loss under defined t est conditions (ASTM Method D-93-10a and ASTM Metho d D86-11a, respectively.) The proposed amendment upda tes the vapor tightness definition to reflect a det ection limit

of 500 ppmv rather than 1000 ppmv, consistent with Rule 1178 - Further Reductions of VOC Emissions fro m

Storage Tanks at Petroleum Facilities, and historic ally achieved in practice by industry. The propose d amendment

also includes additional administrative changes to further clarify rule requirements, streamline recor dkeeping and

reporting requirements, and improve overall enforce ability.
