Amendments to Regulation 8, Rule 5 are being proposed in order to achieve emission reductions required as part of the Final San Francisco Bay Area Ozone Attainment Plan (OAP) adopted June, 1999. The proposed amendments to Regulation 8, Rule 5 are derived from Control Measure SS-07 of the OAP.

• Effective June 1, 2000, slotted guidepoles on organic liquid storage tanks must be equipped with gaskets, wipers and pole sleeves to minimize evaporative emissions.
• Operators seeking an exemption from the rule to take tanks out of service for preventative maintenance will be required to provide written certification of tank compliance and to minimize emissions during the exemption period.
• The minimum required extension below the liquid surface for metallic shoe type seals in internal floating roof tanks will be changed.
• Definitions will be added for gauge floats, guidepoles and zero gap pole wiper seals.
