( vION COMMSSION <br /> i <br /> i <br /> of September 30, 1993 <br /> Ummissioners tet: Marry Desrosiers, Gertrude Simmons-Ferriday, John <br />' Johansen, Frank Homeyer. <br /> 6;55 PUMI * Bennett Gordon advised he received an Order of Conditions <br /> for his dock which has existed since 1980 and one of the conditions stated that <br /> the piles be non-CCA treated and not creosote. He had agreedto do this, if it <br /> was viable, and he has done some research on this. The plastic wood concept looks <br /> okay, but the strength when used as a piling that takes side loading, is approx- <br /> imately equal to 1 - 1-1/2 inch galvanized pipe. Oak is pkay but has a life of <br /> 10 to 15 years; the cost is the same as CCA. <br /> The third possibility is Greeneart which is very expensive; approximately double <br /> the cost of pressure treated and very hard to get as it comes from south America. <br /> It is possible it may not be allowed in the future because it is a luted source <br /> material. It also has structural problems as it tends to split, <br /> He has not found any reasonable alternative to CCA treated piles. Also, he has <br /> noted his property is not in any shellfish zone and has never seen anyone shell- <br /> fishing in front of his property. He requested either of two things, each of <br /> which would require an amended order. First, he would request that he be allowed <br /> to put in the pressure treated piles or alternately that he be allowed to take <br /> CCA treated piles and cover them in the water imer ion area with a lager offiber- <br /> glass which would not be done until the piles are thoroughly air dried to leach <br /> out most of the chemicals and then it would be coated with a layer of fiberglass. <br /> Mrs. Ferriday asked if he had looked into cedar. He advised cedar does not last <br /> too much longer than the oak, 10 to 15 years. <br /> Mr. Gordon stated he read the article given to him by the Agent on CCA leaching <br /> and was not impressed. He described the process used and questioned the reasearch. <br /> He fed.t the toxic affect of CCA is over-rated in this case with three pilings. <br /> Mrs. Ferriday asked if anyone had ever tried leaving them in some water for three <br /> months to allow them to leach out? Mr.' Sherman asked what would thea be dome with <br /> the leachate, <br /> Mr. Gordon also pointed out there was no public discussion on this before it became <br /> a policy of ConComm. He was not aware of it until he came to the meeting. <br /> Mr. Sherman stated the Conservation Commission had several discussions on it when <br /> the Shellfish Commission asked that the Commission consider not using CCA. <br /> Mr. Gordon advised there is a total of two sentences in the minutes; that is all <br /> he was provided. He quoted, "It was voted as a polio that the Commission request <br /> that this not be used for pilings". It has gone from request to putting it as an <br /> Orden of Conditions, there is a big difference there. He would agree to put In <br /> the plastic ones, if they would have worked. <br /> Mir. Desrosiers asked if he was planning to put on a coating of fiberglass, or <br /> just the cloth? Mr. Gordon advised the palings would be laid out in the sun for <br /> two months to dry out, then tape polyester resin, coat the appropriate area and <br /> Put a layer of fiberglass cloth over that, saturate it again with fiberglass <br /> resin using one of the serrated rollers. He felt this is a reasonable compromise. <br /> Mr. Homeyer asked the expense to do this? Mr. Gordon the cost to be $100 for <br /> each pile, labor free. To pay someone to do it would be approximately $150 per <br />
