Strict application of the requirements in the ANSI B77.1 Standard may not be appropriate in every instance. Upon written request by the holder, the Authorized Officer, with appropriate consultation with Staff Engineers (as required in FSM 7300-2000-1, 7321.21), may grant exceptions from the requirements in the ANSI B77.1 Standard. The holder’s written request for an exception must include the following: a. Specification of the current condition via a written description, photographs, a video or engineering drawings, and a statement as to why it does not conform to the ANSI B77.1 Standard. b. A description of the work that would have to be performed or the operational condition that would have to be implemented to meet the ANSI B77.1 Standard, including a statement as to how meeting the ANSI B77.1 Standard would constitute an unreasonable operational or design condition and estimates of the time and cost (for example, for engineering, materials, equipment, and labor) that would be involved. c. An example of why granting the exception would not create a safety hazard to the public. The explanation should include but not be limited to the operational history of the passenger ropeway, existing devices or methods that enhance the safety of the R4 SUPPLEMENT 7300-2009-1 EFFECTIVE DATE: 06/08/2009 DURATION: This supplement is effective until superseded or removed. 7320 Page 4 of 13 FSM 7300 – BUILDINGS AND OTHER STRUCTURES CHAPTER 7320 – TRAMWAYS, SKI LIFTS, AND TOWS passenger ropeway, and the history of similar passenger ropeways with similar conditions. d. If the exception is granted, work that would be performed or operational conditions that would be implemented for public safety by the holder. e. For new passenger ropeways, a letter with an original seal applied by means of a rubber stamp, signature and date, by a Qualified Engineer attesting that the passenger ropeway is to be designed and constructed using devises or methods that are comparable to those required in the ANSI B77.1 Standard. f. For an existing passenger ropeway, a letter with an original seal applied by means of a rubber stamp, signature and date, by a Qualified Engineer attesting that the passenger ropeway is to be designed and constructed using devices or methods that are comparable to those required in the ANSI B77.1 Standard. In addition, a written certification from the holder stating that the passenger ropeway has been operated safely and without any passenger ropeway incident related to the feature for which the exception is requested and certification is supported by information requested in paragraph c. g. Authorized Officer may grant an exception even if the holder does not satisfy all the requirements in paragraphs e and f above if the Authorized Officer (FSM 7320.44) determines that the exception request does not involve a change in certified equipment design or operating parameters for passenger ropeway. 2. The Authorized Officer shall notify the holder as expeditiously as possible in writing of its action on the request. Granting the exception shall not bind the Forest Service to allow an exception for another ropeway of the same or a similar design. The approval to operate with an exception shall state whether the exception is for limited duration and/or requires review and renewal upon application by the holder at a specified time or shall apply until such time as changed conditions or new information indicate a review is necessary and a new exception request is required. Where appropriate, the exception should specify periodic review to determine if a new exception request is required. If the request for an exception is denied, Authorized Officer may allow the holder to request the decision be reconsidered with additional relevant information or appeal the decision through the disputes process stated within permit. 3. To address the safety concerns associated with a passenger ropeway, the Authorized Officer may require special tests or review by a Qualified Engineer or Tramway Specialist (as defined in FSM 7320.5) agreed upon by both Authorized Officer and the holder. The Qualified Engineer or Tramway Specialist shall be independent of the holder. The special test or independent review shall be conducted to ensure that the passenger ropeway is designed and constructed using devices or methods that are comparable to those required in the ANSI B77.1 R4 SUPPLEMENT 7300-2009-1 EFFECTIVE DATE: 06/08/2009 DURATION: This supplement is effective until superseded or removed. 7320 Page 5 of 13 FSM 7300 – BUILDINGS AND OTHER STRUCTURES CHAPTER 7320 – TRAMWAYS, SKI LIFTS, AND TOWS Standard.
