6.0 - Unihose

6.1   When do I need to replace my non-Unihose multiproduct (non-Unihose) dispensers (i.e. 6-packs) with Phase II Unihose multi-product (Unihose) dispensers?

Answer:  If your non-Unihose dispensers were installed before April 1, 2003, they may remain in use for the remainder of their useful life unless major modifications are made to your facility. Major modifications include addition, replacement or removal of 50 percent or more of the buried vapor piping or replacing dispensers.


6.2   My non-Unihose dispenser was damaged by a customer (end user) and needs to be replaced. Do I need to replace it with a Unihose dispenser?

Answer:  No. Dispensers damaged as a result of an accident or vandalism may be replaced with the previously installed type dispenser.


6.3   I installed six non-Unihose dispensers before April 1, 2003. Over the last few months I replaced two dispensers due to end user damage. I now must replace a third dispenser due to further damage from end users. Is this considered the 50 percent limit for replacing non-Unihose dispensers? Am I required to replace the remainder of my non-Unihose dispensers?

Answer:  No. The 50 percent replacement is not a cumulative total as long as the replacement is necessary because of damage.


6.4   Do I need to replace my non-Unihose dispensers with Unihose dispensers if I am replacing a blender or sensor?

Answer:  No.


6.5   I am replacing an under dispenser spill containment for my non-Unihose dispensers. Do I need to replace the dispenser with a Unihose dispenser?

Answer:  No, if the under-dispenser containment instalation is initiated before January 1, 2004.


6.6   If I install a Unihose dispenser today, will it be allowed to stay in use beyond 2008?

Answer:  Unihose and non-unihose dispensers that are eventually certified as part of EVR Phase II systems can be used beyond 2009.
