Johnson, Chairperson <br />RE: National Work Group on Leak- Detection Evaluation's List of Third -Party <br />Evaluated Leak Detection Equipment/Procedures <br />Ir you are reading this memo, you have received our latest edition of the list. We would appreciate any comments you <br />have concerning the list. Please comment to me at the address, phone number, fax number or e-mail address listed on <br />the next page. <br />If vou need to contact other members in the work group, the same information is included for them on the next page. <br />Also, the work group team and team leaders are listed on the page following the member list to help you determine who <br />you may need to contact. <br />Please send new evaluations and/or protocols to be evaluated by the work group to my attention at the address on the <br />following page. To enable the work group to properly review the third -party tests, three (3) copies of all applicable <br />information indicated in the enclosed "Leak Detection Equipment Review - Document List" must be included. <br />Since the draft list was sent out back in January of 1995, the list has sometimes been referred to as the "EFA work group <br />list of approved leak detection equipment". The work group and EPA are concerned that similar statements may begin <br />to appear in sales literature distributed by vendors. We request that you do not refer to the list in this way for the <br />following reasons. <br />I . This is not an EPA or EPA work group list. This draft list was prepared by an independent work group <br />consisting of state and EPA members. <br />2. Neither EPA nor the work group approve leak detection equipment or procedures. The draft list does not <br />includc "approved" leak detection equipment!procedures. It includes leak detection equiptnente"procedures that the <br />work group reviewed and confirmed, were third -party tested in accordance with either an EPA or other acceptable <br />test protocol, and the test confirmed that the equipment/procedures meet EPA performance stwidards. Approval or <br />acceptance of leak detection equipment and procedures is the responsibility of the implementing agency, which in <br />most cases is the state environmental agency. <br />We try to send only I copy of the list per company per location. If you received more than I copy at your <br />location, or if the copy needs to be sent to another person, please notify me and we will make the necessary <br />corrections. <br />Enclosure: Work Group Members, Work Group Teams, Leak Detection Equipment Review - <br />Document List <br />492 <br />Appearance on this list is not to be construed as an endorsement by any regulatory agency nor is it any guarantee of the performance of <br />the method or equipment. Equipment should be installed and operated in accordance with all applicable laws and regulations. <br />
