Going to Step C and then the three small "is;in the Scope of Work is an outline for an operating procedure that would be adopted to de-energize the Intertie when an alarm is triggered. Mr.Paul Williams (Dryden &LaRue)gave a presentation outlining the aspects of major issues involved in determining the minimum ground clearance acceptable under unbalanced loading conditions. The following discussion ensued to determine factors involved in setting minimum ground clearance. The NESC authorizes a base clearance of 14.5 feet over restricted areas. There's going to be four parts to building up a clearance under an unbalanced load.The first part is the electrical clearance component and that's basically what distance a 138kb line could arc across.That is a subjective calculation.He put 4 and a half feet there;so the electrical component is 4.5 feet. The next part is snow depth.There were three ways he determined possible snow depth.The first one is information from four seasons of snow patrols.The maximum snow depth ever recorded was 64 inches. The other way is to do a mathematical model and do a 35 year return period or use 50 years;it makes the calculation a little more interpretive.Taking data that is available throughout the area there he came up with 95 inches or almost 8 feet for a maximum snow depth in this area.8 Feet has never been recorded anywhere to date. The next component is clearance adder.It's a safety factor to account for survey errors or plotting mistakes on where the towers are actually located.From a design standpoint they use a minimum of up to three feet. The last addition to calculations is the obstruction height under the line.Examples given were a skier with an extended a ski pole with a total reach of twelve feet in height;and a snocat with an eight foot tall antenna on the top with a total calculated height of sixteen feet. The final calculations will need to use factors including NESC calculations,clearance adder,and obstruction height to determine minimum ground clearance. With ground clearance determined;calculations can be made by Dryden &LaRue to determine load limits on the line and outline a new Standard Operational Procedure for de-energizing the Line to be submitted to a Third Party Review. Discussion of the Snow Patrol ensued and it was determined that duel Patrols leaving from Talkeetna and Wasilla are an option although not within the present Budget. Mr.Del LaRue (Dryden &LaRue)suggested the following upgrades to the current system in addition to the patrols:add stations;change out almost all of the equipment to something newer,or add some cameras to give dispatch a visual as to what's going on. It was determined after some discussion that inclinometers do not give out enough valuable information to be installed on any new Stations.Every Tower is being converted to have PV Panels. Mr.Copoulos made the point that Dryden &LaRue need the IOC to make decisions on these issues so that they can move forward with the rest of the Scope Cost Estimate. Mr.Bob Drake (MEA)asked for a change to be made in the Scope of Work.It reads "currently the Line is patrolled from Tower 1 to Tower 231”.However,there are times when the patrol cannot be done due to unfrozen streams,marshes,etc.,and therefore,that part should be changed. Mr.Dale answered that perhaps it should read "when accessible safety patrols will verify the conditions'. Mr.Drake made the point that that on the third page under "E”single "i”the Scope reads that "inquiries should be confidential and should not specifically name any organization”.He disagreed with this statement and said that he believes that it should be taken out.Information should be verifiable and the source of the information known. A discussion ensued as to how confidentiality can become an issue when discussing such inquiries. 1B.Operating Procedure to de-energize the Intertie Mr.Copoulos read from the existing Procedure:"if the Patrol!Contractor cannot initiate Patrol at first light as a result of inclement weather and the snow continues to load the conductor spans and one or more load cells are in alarm the Southern Controller shall initiate aerial Patrol'. He went on to read the new Operating Procedure as follows:"to de-energize the Intertie when an alarm is triggered under the current parameters for load cell alarms”. The purpose of this new procedure is to deactivate the Intertie when an alarm goes off.This requires setting a new parameter for load cell alarms.If this cannot realistically be done then other solutions will have to be looked at such as limited Inset Towers set in particular problem areas or some other monitoring. Once the Procedure has been determined it will be submitted to a Third Party Review to be evaluated to help determine whether this system can be deemed as safe and reliable. Mr.Henri Dale (GVEA)made the comment that a new budget will be voted in soon.The money put into furthering the Snow Load Mitigation Project will be voted on as an Item in the upcoming new budget. He went on to ask everyone to email him their calculations concerning minimum ground clearance and added that the numbers adopted will be by vote by the majority as spelled out in the Intertie contract. 4.Next Meeting Date The next meeting will be scheduled in July 2005,possibly after the BMC meeting at MEA. 5.Adjournment The Meeting adjourned at 12:25pm.
