    General Information
    The Propane Education & Research Council (PERC) is a non-profit 501(c) 6 trade organization authorized by the Propane Education and Research Act of 1996 (PERA), Public Law 104-284.  PERC was created “to enhance consumer and employee safety and training, to provide for research and development of clean and efficient propane utilization equipment, and to inform and educate the public about safety and other issues associated with the use of propane.”   This Request for Proposals (RFP) is not subject to any federal or state procurement law or regulation.

    A 21-member Board of Directors appointed by the National Propane Gas Association and the Gas Processors Association governs PERC.  Members include propane retail marketers, producers, transporters, and agricultural cooperatives, as well as representatives of allied service and supply industries.

    Proposals to Provide Services Sought
    PERC is currently seeking bids from qualified contractors to provide the propane industry with a “Proposal for Testing and Evaluation of Pressure Relief Valves on Propane Transport Vehicles, Bulk Tanks, and Customer Tanks.” This project would evaluate potential issues related to Pressure Relief Valve (PRV) degradation in various service environments.

    Project Background
    Spurred by an incident in which the relief valve spring failed on a bulk transport truck, a product safety notice was issued by a manufacturer in October 2005 regarding the potential for damage to certain relief valves caused by their service environment.  In particular, the notice identified that the presence of atypical contaminants in the fuel may cause relief springs to break, adversely affecting system operation and reliability. Spring breakages can result in the unintended release of product and possibly result in personal injury, property damage, explosion, fire, or chemical contamination.

    While there may be no incidents of this type of failure on stationary bulk storage tanks, there remains a concern that a similar situation could occur in the future.  Because of the potential safety issues, testing the effectiveness of different pressure relief valves exposed to varying concentrations of contaminants and different environments may be needed to better understand the phenomena and to identify measures that may prevent future occurrences.

    Scope of Work
    The scope of work for this project is set forth below. The deliverable for this project will be a detailed report outlining the test results for PRVs exposed to various service environments, and providing recommendations for improving relief valve performance.

    This project is focused on PRVs for propane service on transport vehicles, bulk plant installations, and customer tanks. The project and evaluations should examine potential failure modes that could result in safety problems.

    1. •Your RFP response should include a task to develop a survey and compile the results of the survey that inquires about PRV problems experienced by propane marketers related to transport vehicles, bulk tank installations, and customer tanks.  The results from the survey should be compiled into a spreadsheet, or similar format, so that any trends in potential PRV failures can be identified.  The number of surveys to be submitted to the propane marketers and the approach should be suggested in the response to this RFP.
    2. All PRVs should be tested in accordance with the plan provided in Attachment A, and results of the tests should be recorded for each PRV that is tested. Vibration may also be a concern for PRVs installed on transport trucks; the bidder should take this into consideration in their response to this RFP. If you believe that additional tests or test modifications are necessary to accomplish the purposes outlined above, your RFP response should so state, and should identify the additional tests or modified tests that you propose to add to the protocol and reasons for doing so. Your proposal should describe the test protocol that you propose to use as well as reasons for modifying the approach suggested in this RFP.
    3. Your response to this RFP should include provisions to purchase from each manufacturer at least three PRVs used on propane transport trucks, bulk tank installations, and customer tanks for detailed testing to determine potential catastrophic failure modes that could result in safety problems.  If you believe that more or fewer PRVs should be gathered and tested in order to accomplish the purposes outlined above, your RFP response should so state, and should identify the number of PRVs that you propose to gather and test. Your proposal should describe the number of PRVs that you propose to gather for each manufacturer and type of PRV and justification for the sample size proposed.
    4. The winning bidder will be responsible for collecting the PRV test samples, procuring the control sample of propane, documenting the compositions of the control sample, creating the test gases, calibrating instrumentation, and completing the testing of all samples in an agreed-upon time frame.  Written monthly progress reports shall be submitted to PERC if the project is expected to require more than three months.  Allowance for at least one witness test by PERC representatives should be included.  The final report should include a description of the test methodology and equipment as well as the results for each PRV tested.  The data should be presented in such a way as to make it easy to compare the performance of the samples, and should be provided in hard copy and electronic format.  Calibration records for instrumentation should be kept according to good laboratory practices.
       

    Qualifications
    The successful contractor will be familiar with the LP Gas industry, its codes, regulations, and common practices used throughout the industry.  The contractor must demonstrate and describe its ability to anticipate, coordinate, and carry out all aspects of the project.   Project completion dates will be an important factor in selecting a contractor.  PERC anticipates the award date for the project to be December 7, 2007.  Eligible applicants for this solicitation are profit organizations, not-for-profit institutions and organizations, educational institutions, and individuals.
