per 2017 NEC can a service panel board be located in a pool equipment room with chlorine storage? this is an indoor public pool.
No. It is considered a corrosive environment per 680.14 (new section - 2017 NEC). Also, see 110.11. Any time I allow a panel in an area like that, it is NEMA 4X and it will be spec'd out on the plans that way.
Thanks Nick. One of their remedies is to create a small room around the panel. If it meets the working space requirements, is that acceptable?

I suppose so, as long as it meets all other code requirements, including the building code. By building a room around it, equipment will no longer be considered "within sight." It may affect your disconnecting means for all the equipment in the room.
Something doesn't seem quite right.
Indoor Public Pool, hmmmmm. Either it's an old School, YMCA, or something that was not Public - and has become Public. Either way, it was not built within the last decade. Like Nick pointed out, NEMA 4X (Stainless Steel Enclosure and Conduit),along with other Equipment (Pumps/Controls/Lighting/Outlets), there is a plethora of other Code requirements like Wire Type, Signage, general Lighting, Non-Water Fire Suppression System (Chlorine cannot come into contact with water - ironically), it goes on and on. In addition, there is probably evidence that the present Power Service is showing signs of deterioration or corrosion of the Copper, which is what started this whole thing.
I might suggest moving the Chemicals to a separate Locker or add a Modular Storage Unit prefabricated specifically for Chlorine Storage including Temperature Control, Ventilation, Fire Suppression, etc.
