Dear  Mr. Eckert:
            This letter is in response to your December 16, 2015  request for the Federal Highway Administration (FHWA) to review a roadside  safety device, hardware, or system for eligibility for reimbursement under the  Federal-aid highway program. This FHWA  letter of eligibility is assigned FHWA control number CC-104B and is valid  until a subsequent letter is issued by FHWA that expressly references this  device.
            ***Decision***
            The following devices are eligible, with details provided  in the form which is attached as an integral part of this letter:
              Vorteq® Truck Mounted Attenuator (TMA) Modification***Scope of this  Letter***
            To be found eligible for Federal-aid funding, modified  roadside safety devices should meet the crash test and evaluation criteria  contained in the National Cooperative Highway Research Program (NCHRP) Report  350. However, the FHWA, the Department  of Transportation, and the United States Government do not regulate the  manufacture of roadside safety devices. Eligibility for reimbursement under the  Federal-aid highway program does not establish approval, certification or  endorsement of the device for any particular purpose or use.
      This letter is not  a determination by the FHWA, the Department of Transportation, or the  United States Government that a vehicle  crash involving the device will result in any particular outcome, nor is it a  guarantee of the in-service performance of this device. Proper manufacturing,  installation, and maintenance are required in order for this device to function  as tested.
            This finding of eligibility is limited to the  crashworthiness of the system and does not cover other structural features, nor  conformity with the Manual on Uniform Traffic Control Devices.
            ***Eligibility for  Reimbursement***
            FHWA previously issued an eligibility letter for the  roadside safety system described in your pending request. Your pending request  now identifies a modification to that roadside safety system.
      The original  roadside safety device information is:
Name of  system:
               	  Vorteq® TMAType of  system:
               	  Crash CushionDate  of original request:
               	  August  23, 2009Date  of original FHWA eligibility letter:
               	  December  23, 2009FHWA  Control number:
               	  CC-104The pending  modification(s) consists of the following changes:
            Reduced hole size in side plates from  9/16" to 17/32" for a rivnut application in fender mounts.
Added slots and flat washer to battery tray  brackets to ease assembly of parts.
Updated decal to include bolt part number for  ordering replacement bolts.
Added Safety Chain Length as an option for  customers requiring longer safety chains to their trucks.
Added washer between bolt and X-Brace  component to maintain correct fit over slot.
Modified the channel used for QuadGuard  transition bracing by adding a 1" ×
 11/16" slot for galvanizing  drainage.
Modified the steel nose on QuadGuard II by  adding a small ink "W" letter on the side below the attachment holes  for identification of wide nose components.FHWA concurs with the recommendation of the accredited crash  testing laboratory as stated within the attached form.
            ***Full Description  of the Eligible Device***
            The device and supporting documentation, including reports  of the crash tests or other testing done, videos of any crash testing, and/or  drawings of the device, are described in the attached form.
            ***Notice***
            If a  manufacturer makes any modification to any of their roadside safety hardware  that has an existing eligibility letter from FHWA, the manufacturer must notify  FHWA of such modification with a request for continued eligibility for  reimbursement. The notice of all  modifications to a device must be accompanied by:
  
              Significant modifications – For these modifications, crash        test results must be submitted with accompanying documentation and        videos.
                Non-signification modifications – For these modifications, a        statement from the crash test laboratory on the potential effect of the        modification on the ability of the device to meet the relevant crash test        criteria.FHWA's determination of continued  eligibility for the modified hardware will be based on whether the modified  hardware will continue to meet the relevant crash test criteria.
            You are expected to supply potential users with sufficient  information on design, installation and maintenance requirements to ensure  proper performance.
            You are expected to certify to potential users that the  hardware furnished has the same chemistry, mechanical properties, and geometry  as that submitted for review, and that it will meet the test and evaluation criteria  of the NCHRP Report 350.
            Issuance of this  letter does not convey property rights of any sort or any exclusive privilege. This letter is based on the premise that  information and reports submitted by you are accurate and correct. We  reserve the right to modify or revoke this letter if: (1) there are any inaccuracies in the information  submitted in support of your request for this letter, (2) the  qualification testing was flawed, (3) in-service performance or other  information reveals safety problems, (4) the system is significantly different  from the version that was crash tested, or (5) any other information indicates  that the letter was issued in error or otherwise does not reflect full and  complete information about the crashworthiness of the system.
      ***Standard Provisions***
      To prevent       misunderstanding by others, this letter of eligibility designated as FHWA       control number CC-104B shall not be reproduced except in full. This letter and the test documentation       upon which it is based are public information. All such letters and documentation may       be reviewed upon request.
              This letter shall not be       construed as authorization or consent by the FHWA to use, manufacture, or       sell any patented system for which the applicant is not the patent       holder.
              If the subject device is a patented product it may be  considered to be proprietary. If  proprietary systems are specified by a highway agency for use on Federal-aid  projects: (a) they must be supplied through competitive bidding with equally suitable  unpatented items; (b) the highway agency must certify that they are essential  for synchronization with the existing highway facilities or that no equally  suitable alternative exists; or (c) they must be used for research or for a  distinctive type of construction on relatively short sections of road for  experimental purposes. Our regulations  concerning proprietary products are contained in Title 23, Code of Federal  Regulations, Section 635.411.Sincerely yours,
            Signature of George E. Rice, Jr.
