STAFF UPDATE Ms. Cochrell said the Board will be discussing the RMLA conference and Board members plans to attend the conference at the end of today’s meeting. Ms. Cochrell said the next rule book will have an effective date of May 15, 2016. The rulebook will be available on the Tramway webpage for the industry around May 15. Hard copies will be given to Board members and Staff at a future meeting. Ms. Cochrell stated the next Board meeting would be held on May 4, 2016 in Grand Junction at 10:15 a.m. The location of the meeting will be determined and posted on the Board’s website in the near future. With this, the April 28, 2016 Board meeting will be cancelled. The deadline for agenda items for this meeting is April 7, 2016. Ms. Cochrell said the next Technical Committee is scheduled for April 8, 2016 via conference call at 1560 Broadway, Suite 1550 Small Conference Room at 9:00 a.m. The deadline for the meeting is March 25, 2016. Ms. Cochrell informed the Board that travel mileage went from .52 to .49 as of January 1, 2016. Larry Smith, Supervisory Tramway Engineer, said surveys will start going out with inspection report starting in the Fall 2016 season. The Division is working on collecting data from each of the Board’s industries to get public input on how we are doing. He will discuss this more at RMLA. Mr. Smith said Granite Gorge Ski Area in New Hampshire had a chair slide back due to a grip slippage. Two were injured in the chair behind the chair that rolled back. Mr. Smith showed photos of the recent Breckenridge wind event with winds clocked over 105 mph several times. There was not any tramway damage at the area. Mr. Smith show photos of the electrical fire that occurred on a detachable chairlift terminal in Ski Bromont, Quebec. Mr. Smith showed photos of the sheave failure at Loveland. The sheave fell off due to a hub bolts not being torqued correctly on three towers that were modified during a major modification last summer. The area inspected and torqued tested all the towers and no further indications were found.

Mr. Smith showed photos of a bullwheel liner at Loveland where the cable was hit by lightning. The lightning passed through the rubber lining and went to the steel bullwheel through a gap in the edge of the liner. Mr. Smith showed photos of a rope jack failure that occurred at Black Mountain in New Hampshire. The rope jack is used to raise the cable off the sheaves for sheave maintenance. Mr. Smith showed photos and said the Canon Mountain Tram in New Hampshire recently had an evacuation due to an electric motor failing. Approximately 40 people were evacuated when the lift shut down. Mr. Smith showed photos of the Keystone Outpost Gondola that developed grip jaw cracks. He said the area is in the process of replacing the jaws and the remaining cabins that have similar jaws of this design have been removed from service. Mr. Smith showed photos of the Copper Mountain sheave jam that occurred on the Super Bee lift. The flange was worn and the rope position switch damaged as the cable wore down through the liner while the sheave was not turning. Mr. Smith show photos and said that cracks have been recently discovered on Doppelmayr depress tower heads. When it was discovered on three towers at two different areas, he sent out an immediate inspection notice on January 25, 2016 asking areas who have the Doppelmayr depress tower head to inspect their depress towers and report back if cracks were discovered. In total, there were two areas in Colorado with three cracked towers and three areas outside Colorado that discovered cracks. These cracks are showing up not just in Doppelmayr equipment but in other manufacturer equipment. Mr. Smith showed photos of corrosion in tower cracks on a Heron Poma lift located in the eastern US due to acid rain. Mr. Smith showed photos of a Riblet chair that fell of a lift at Heavenly in California and explained the failure of a set screw caused the chair to come off the clip. None of the Riblet chairs in Colorado have that type of modification. Mr. Smith showed photos of a sheave flange crack on the Vail gondola. It is believed that the crack developed due to too much pressure on the flange when the liner was replaced. Mr. Smith said Winter Park had some rope damage from multiple new LE grips. He showed photos showing edges on a grip that caused the damage. The sharp edges of the jaws causing the problems were ground down and the cable inspected for immediate damage. The area will have the wire rope inspected more closely this summer during their maintenance season to verify that further damage was not done. Mr. Smith showed photos of cable corrosion at the tieback for the drive terminal on a surface at Cranor Hill. As a result of the inspection discovery, the area replaced the cable tiebacks prior to operation to the public.

Mr. Smith showed photos of the electric motor damage at Keystone. The failure was on the stator, which is very unusual failure point. Keystone is checking further into the failure to find an explanation. Mr. Smith said Timberline Ski Resort in West Virginia had a tower failure. He showed photos where a Brovig tower head failed and fell to the ground. The failure was due to that lack of penetration of the weld. A service bulletin issued in 1987 was not followed to address the potential problem on that lift. Mr. Smith showed photos of the drive shaft failure at Beaver Creek. The failure was in a weldment of the drive shaft. Richard Burkley, Board Chair, said The Rocky Mountain Lifts Association (RMLA) Board is finalizing the syllabus for this year’s annual training seminar in Grand Junction May 25. The classes selected will complement the session from past years to give lift maintenance and operations personnel continued comprehensive knowledge of maintaining and operating lifts. He will circulate the syllabus when it is finalized.

FINAL COMPLETED MINUTES FROM THIS MEETING WILL BE POSTED AFTER THE BOARD APPROVES THEM AT A FUTURE MEETING.

Supplements to the Policies (effective February 25, 2016) · Policy 9 Clarification of modifications list

SUPPLEMENT TO

STATE OF COLORADO DEPARTMENT OF REGULATORY AGENCIES COLORADO PASSENGER TRAMWAY SAFETY BOARD 2015 RULES AND REGULATIONS Effective Date: February 25, 2016 In the CPTSB Rules, the following policy has been revised:

9. Clarification of modifications list. CLARIFICATION OF MAJOR MODIFICATIONS A major modification is defined as a significant change to the tramway's certified design or certified construction and materially affects the tramway's integrity, operation or control (see rule 21.1.2). The following list is intended to provide guidance in determining those changes to the tramway that are properly classified as major modifications, however, this list is not all inclusive and it must be recognized that the circumstances pertaining to a particular modification may justify reclassification to another category. Therefore, it is the responsibility of the area operator to exercise sound judgment and to consult the Board if further clarification is needed. All Major Modifications require an acceptance test (see rule 21.3.7) and shall be completed prior to public operation of the passenger tramway. A CPTSB Inspector shall be present during each acceptance test (see rule 22.5.1). All Major Modifications are required to meet the current CPTSB and ANSI Standards. a) A change in the design speed of the system. 1. Any increase beyond certified design. Note: A decrease is not a major modification. b) A change in design capacity by changing the number of carriers, spacing of carriers, or load capacity of carriers. 1. Carriers may be added or removed to accommodate normal rope stretch or relocation in rope splice area. Note: If this is done within the certified design parameters, it is not a modification. 2. Increasing load capacity is interpreted to mean changing the number of passengers (i.e. double chair to triple chair). Note: A change in carrier spacing which results from normal operation (i.e. grip slippage) is not a modification. Supplement 4 Effective: February, 2016

c) A change in the path of the rope. 1. Adding or removing midway load/unload terminal. 2. Moving a tower. 3. Change in tower height or number of towers. 4. Change in line gauge. 5. Moving a terminal is at a minimum a major modification and may be considered a relocation of the lift upon Board review. d) A change in the type of brakes and/or backstops or components thereof. 1. A change to the application mechanism, defined as the energy used to set brake (i.e. weights to springs, springs to hydraulics, or different types of weights, springs or hydraulics, etc.). Note: If the specifications of the component are equivalent, then it is treated as a one for one replacement and not a major modification. e) A change in structural arrangements. 1. A change to the cross arm (i.e. removing angle brace and making it self supporting). 2. Tower. 3. Terminal support. f) A change in power transmission equipment or type of prime mover or auxiliary engine. 1. An increase or decrease in the horsepower of an electric motor or internal combustion engine. 2. Changing an AC to DC or vice versa, etc. 3.
