The White Salmon Valley School District plans to apply with the state for a waiver of classroom hours requirements after losing 11 school days to snowy conditions over the winter.  District Superintendent Jerry Lewis says Washington Governor Jay Inslee had already issued an emergency proclamation to allow cancellation of five days because of the difficult winter weather the state experienced.  Lewis noted the district used its three built-in make-up days and added two days to the end of the school year.  Lewis says the waivers have been approved routinely around the state.  He adds the White Salmon district waited to make the application until now because it can only be done once, and they wanted to make sure there was no more snowy weather before submitting it.
