I did alot of research before I started doing docks here in upstate New York. I contacted the EPA to tell them what chemicles I would use and how I would do the job. I wanted to make sure I was doing everything to their satisfaction. I also wanted to get something in writing from them stating I was meeting their standards. I did not want some conservation officer, neighbor, or anyone else to give me a hard time.
With the help from Wolman. They sent me msds sheets as well as toxology test on Rain coat, percarb cleaner and deck strip. They sent this information to my Epa contact along with a letter.
To make along story shorter, the Epa said they had no guidlines on the books. They said they would not give me permission in writing to do what I wanted however they would not stop me either. They admitted it was a gray erea that they did not want to commit to.
Wolman said all the above products are water soluble and would not harm plant life or any living things even the deck strip. They discourge stripping a dock that might have been sealed with an oil based stain, so you will want to be sure of what stain is there if you need to strip. Only apply a water based semi trans parent stain as well.
I hope I was of some help. ( please forgive the spelling)
