     I can't use Mids (dead computer) but looks like you're building for range defense (and S/L resists).  Team build or solo or either?

• Drop 1 slot from Hasten and Benumb and trim the number of Recharge IOs to 2 in each.
• Then boost the IOs in Hasten and Benumb to +5.  Should save you a couple slots with virtually no loss in cool down.
• I'd probably try to get Hasten in there earlier particularly if you'll exemp often with the build.  Ditto for Combat Jumping (a self admitted CJ+Hurdle junkie).
• Keep in mind that both your Shields and Arctic Fog can take defense and resistance IOs ... which means you've got lots of options for all those yummy special IOs.  That's a build advantage in Cold to exploit in my opinion.
• Someone is bound to come along and point out Infrigidate can take several damage procs, so I'll beat them to it.
• Consider grabbing Snow Storm, 1 slot wonder.  Snow Storm+Rain of Fire+Sleet is mobs crawling around the area trying to avoid the area (and not attacking you) all while getting pounded.  Even without high levels of recharge alternate Sleet and RoF plus Snow Storm and foes are ground bound in slo-mo.
• Heat Loss can also both solve a lot of end issues and be used on top of RoF, Sleet etc. to slow your foes movement and recharge.  And like Sleet debuffs resistance.

Overall looks like a solid build.
