16. Temporary and Permanent Closure Requirements Temporary Closure Maintain Corrosion Protection

17. Temporary and Permanent Closure Requirements Temporary Closure If the UST remains temporarily closed for more than 3 months, you must leave vent lines open, but cap and secure all other lines, pumps, manways, and ancillary equipment.
