RE: REVISIONS TO DRAFT SAMPLING AND ANALYSIS PLAN, AREA I THERMALTREATMENT FACILITY

Dear Ms . Jensen :

based upon the telephone conversation held December 20, 1991 between

Dinah Jasensky, Brian Sujata and yourself, handwritten comments by Mr .

Sujata, and telephone conversations with Dean Crippen on January 6, 1992,

we have revised the draft Sampling and Analysis Plan . Due to the number of

people involved in the project, we have prepared a list of revisions to

clarify the changes made over the past two weeks . This list is attached as

Table 1 .

We anticipated that the changes requested on January 6, 1992 would be

incorporated in time for us to express mail the report (8 copies) on

Thursday, January 9, 1992 for arrival at your office on Friday, January 10,

1992 .

Dear Ms . Jensen :

Submitted herewith is the Draft Sampling and Analysis Plan for the

Rockwell Area I Thermal Treatment Facility as requested by Mr . Dean R .

Crippen of your staff. In addition a copy of Analytical Technologies,

Inc .'s "Quality Assurance Manual " is enclosed . This document is referenced

extensively in the quality assurance portion of this Sampling and Analysis

Plan . In reviewing the report, please note that the available background

information was limited . If additional information can be added, we may be

able to more effectively focus the sampling locations . We have not prepared

a Health and Safety Plan specific for the sampling activities . The initial

review of compounds and hazards at the area indicate that Level B personal

protective equipment will be necessary . We would like to obtain information

regarding previous activities at the site prior to writing the Health and

Safety Plan . Desired information regarding previous activities and

background information include the following: tLG;tcy &WI FC-
