The LMCD staTf submitted <br />a report including informat;ion as to wtiich mirltir'le d^jcks a.t e <br />using non-encased plastic foam on the Lake. I hr?t e was informa­ <br />tion as to the f raginenta t ion pr'oblerns at L.:iT.es i d<‘ Marina artd <br />Minnetonka Boat Works-Brown’s Bay and Tatrager Lake. The report <br />explained that there is a difference between "Styrotoam** brand <br />extr-.uded plastic foam and the molded polystyrene expanded bead <br />foam used at Liakeside Mariria and Minnetonka Boatworks. Exampl'^s <br />of the two types of plastic foam were available. <br />Accompanying the staff report were copies of the Orono <br />Ordinance and a technical newsletter from Dow Chemical Co. r*e- <br />porting on buoyancy tests of the two types of polystyrene foam. <br />Jim Dunn, Lakeside Marina, said the December 31., 1994 date <br />in the Orono Ordinance, before which the use of the r>ro<ltjct is to <br />be phased out. is unfair. Tn his case, lie has iusf finished I n-' <br />stall i ng tlie last f ing*?r' on liis f loatin<i docks. Lc?chr an nc't.ed <br />this time frame has been discussed in the committee. <br />Jim Rivers, Windward Marine, said Styrofoam is the only <br />product approved by the State of Oregon and by the Corps of <br />Engineers. It is the product lie uses and he has not had any <br />problems with fragmentation. <br />Bloom asked how lone the products last. Dunn responded that <br />he is estimating 10 to 12 years for the plastic foam in his <br />docks. The life span of the foam depends on tfie density, main <br />tenance and management, <br />Cochran suggested it might be appropriate, when developin«i <br />the Ordinance, to use performance type language such as that we <br />expect the mateiial to be fragmentation proof." Me sa:d there <br />may be other types of flotatioti devices «;le'^eIoped in tlie tfJtnte. <br />In response to a guestion from Penn, Ihib.iult sai^f thei e <br />have been no problems at Windward Marine where the extruded <br />Styrofoam" product IS used
