CCA Timber Life Expectancy

[apd139]

I am looking for a timber design code that specifically discusses the life expectancy of CCA treated timber piles within the salt waters of the United States. I typically use the NDS from American Wood Council to design timber piers but I am doing a post-mortem and need a published source.
