This letter is our confirmation of the retention arrangements you made with representatives of our Examination Division. ', A list of records, retention periods, and any other provisions agreed upon is enclosed. Please sign and return the concurrence copy of this letter, which will indicate that you agree to the arrangements described in the enclosure. A copy of Revenue Procedure 86-19 and a return envelope is enclosed for your convenience. ' ^ If you make any changes in your ADP accounting system or record formats that will affect your ability to comply with these provisions, please notify us. If you fail to respond in writing within 45 days from the date of this letter, it will be assumed that you do not wish to enter into a retention agreement. This letter will then serve as notice that any previous retention agreement is no longer valid and that all machine-sensible records will have to be retained in accordance with Revenue Procedure 86-19 and Revenue Ruling 71-20. If you do not keep the listed records as required, the Service may apply the civil or criminal penalties of Section 6653 (a) and Section 7203 of the Internal Revenue Code. ALB00182 In the course of conducting our tax audits through the use of your ADP records, it may become necessary for us to make new retention arrangements with you. If this occurs, we will meet with you again and enter into a new agreement. If you have any questions, please contact me or L. A. Noble, ADP Focal Point Manager at FTS 562-6485.

Several alternatives we discussed were - 1. a spun acrylic yarn twisted around the phosphor bronze wire - possibly with a polyester mu 11ifilament yarn for strength in winding and weaving. 2. to keep the percent synthetic content low in this yarn you mentioned, we could investigate the use of glass, a non-synthetic material. I think we both agree that the metal wire is still necessary to maintain a stable width in the felt. Albany Felt is still actively pursuing the patent appli cation on the wire content yarn. *j * A substitute for asbestos seems very feasible since it' a the warp yarn that . is the key to the felt and the filling in those styles "just goes along for the ride". . The warp yarns receive the heat and abrasive wear, not the filling yam (as is the case in Style 5702). We'll handle the yarn trials on a PWO basis in the Albany Plant. Let' s not get into the marketing-price of felt considerations at this time. Please ^request yarn cost studies as the trials are developed. The cost of the asbestos yarn is $2.80 per lb. and far outweighs the amount of relatively inexpensive warp yarn used. On a cost basis, the filling yarn used an average felt of style 5878 costs about 6 times the cost of the warp yarn - and 4he warp is the key to a long life on the paper machine. . ` As we discussed, we would expect the use of asbestos to decrease greatly in future use in the dryer felt industry. memo.

F. Longo Copies To: Distribution INTEROFFICE MEMORANDUM Date: October 20, 1975 From: M. J. Josef Subject: Elimination of Asbestos Yarn from Dryer Felts As you know, almost all orders for dryer felts that used to require asbestos yarn have now been changed over to the acrylic/wire yarn. Each plant (Albany & st. Stephen) is now making this yarn. From a manufacturing/quality standpoint, Dryer Felt Design does not see a problem. As far as I know, we have not yet installed a felt using the acrylic/wire yarn, but we don't foresee any problems. I would like to eliminate the use of asbestos entirely by the end of 1976 - we're well on our way to elimination right now. .. . Please notify the salesmen that this across-the-board decision has been made. Our reasons are: ' iliilTf H.09 11 ' 1. coat - the asbestos/wire yarn now costa over S3*fltT"per lb. compared to $1.12/lb. for the a cry lie/wire yarn. On a felt 150 ' x 150" it means a material cost saving of over $1,000.00, ^ ' . ./ 2. need - the warp yarn is the key yarn in the success of a felt, not the filling. The wire will still be there for stability. 3. 0SHA standards - Ralph Hendricks informed me that the nw health stan dards call for sectioning off that part of the plant where asbestos is used; monitoring the level of asbestos in the air; sending employees for expensive physicals each year; and the plain fact that the asbestos " must be dangerous This may be why U. C., Franklin wants to know when the first non-asbestos content felts will be delivered to them. 4. the substitute yarn looks very good and will provide work for Albany"t employees. 5. Albany Felt will be able to reduce its inventory costs for this expensive yarn. Important: If anyone disagrees with this decision, please let me know as soon as possible.

This beam felt, the yam which runs in the machine direction is termed the "L" (lengthwise) yam and the yarn running across the machine is termed the "X" (crosswise) yam. construction gives the fabric a high resistance to bend ing forces. When a fabric is woven flat the warp becomes the "L" 20 DESCRIPTION OF THE DRAWINGS yarn and the filling is the "X" yam. When the fabric is woven endless the warp becomes the "X" yam and the filling becomes the "L" yam since the fabric is woven in tubular form and the endless felt is obtained by cutting off a piece of the tube and turning it 90*.
