Dear Ms. Akhavannik:

The following is provided in response to the conference call between QSA Global, Inc. and your office on 23 June 2015. In that call, it was agreed that QSA would send in revised drawings to clarify the applicability of AWS D17.2/D17.2M as it relates to welds referenced on the Model 650L package. Enclosed is revision N to drawing R65006 which makes this clarification. In addition, we have made some other minor changes to the drawing for clarity at this time. None of these changes is reportable under 10 CFTR 71.95. All changes to drawing R65006 from Revision M to Revision N are described in the following table:

Location Summary Change Change Impact Sheet 1 Weld call out for outer sleeve removed and No impact. Change administrative in nature.

note added referencing Sheet 5 for weld details.

Sheet 2 Notation for weld nut spot weld clarified to Change made for clarity and to avoid any confusion on indicate weld is a "resistance" weld. applicability of AWS D17.2/17.2M for these welds.

Sheet 2 Removed material reference for inner shell. The material specification for the inner shell is shown on sheet 1. Removal of material reference on sheet 2 is to avoid redundancy.

Sheet 3 Added alternate material specification for the This optional, alternate material specification is as good or lock screws (in addition to the material better than the material strength criteria listed in the Lock strength table) applicable to screws installed Screw Table on this sheet. Allowing this specification as after July 2015. Alternate specification an alternative to the current specification for screws after allows screws that meet the July 2015 poses no adverse impact on the component chemical/mechanical properties of ASTM performance or package integrity.

Sheet 5 Revised Note 2 to clarify applicable sections Resistance welding on the 650L package only affects and exceptions to AWS D17.2/D17.2M for Class C welds whose failure will be insufficient to cause resistance welding. the package to fail to meet the regulations. The revision identifies the applicable requirements from the standard.

Sheet 5 Added weld detail (primary and alternate Change in location for primary specification (originally construction) for the outer sleeve weldment. shown on sheet 1). Addition of the alternate construction is equivalent, or stronger than, the primary construction and will have no adverse impact on the package integrity.
