T�tc East Kooch system i s very similar in many respccts to this proj ect area aald has ne�er experienced a pipe break because of freezing and in cightcen ycars of operation. In fact, East Kooch l�as� experienced only two �a�x��arativ�ly nlinor leaks at Iiti stations. The Jac�sk� Bay project actually incorporates better technology and the Court .��ac�s it's design is not likely to cause environmental �.2�z�. L,eak Protection � 5_ Underwater crossings are not iikely to cause leaks as alleged by ihc Plaintiffs. The safeguards of shut off valves, press��r� sensors, warning alarms, remote aIa.�xa, telemetry (SCADA), freeze-6��aI� resistant piping, insulated pipes and equ�pni��.�, heat tracing a��d back up power arc adequate to reasonably insure the s�fc workability of the system in the �vater crossing areas. $eca�sc of these safeguards designed into this system, rock blasting is not likely to cause leaks and small diarncter piping or even the existence of over 240 sewage grinder stations are not likely to result in leaks. 1� The pressure sewer system will utilize high density polyethylene (H]�P c) pipe. T h i s courl i s pe�suadcc� by the evidence presented and finds that if eli�s type of pipe �cezes, it does not burst and will resume its function upon thawing. Furthermore, �owcr outages have historically bce�, ot' very short duration i n the County according i,a tile evidence offered �c�. reccived, lasting usually no more than threc to �o�u� hours A power outage of this duration would not likely cause the pipes to �reez�. 17. In the case of apower outage, crr►exgency power would be a�ra.ilablc to six pump staiioz�s by two trailer-mounted generators storcd at the North �ooc�iichin� Sanitary Sewer Disteict� (north Kooch) facilities. Ail heat-traced s��t�ents of the pipeline would have a backup power outlet for use during cxt�ncled power outages. F Also rc%rred to by �� par[ics as the N�rrl�.
