DUP 1013058 DU 053546 Question 3, List the off-site laboratories you have used and give your assessment of each lab's performance. Cape cear Marshall Lab --Excellent Haskell Lab - Good, cost high Clayton Environmental - Very good Waynesboro Hagar Lab (Denver: - Good Analytics (Richmond) - Good CooDer River Clayton Environmental Consultants - Good Chattanooga Anderson-Nichols Hager Laboratory Richmond Analytics (Richmond) - Certified lab used by Haskell to handle their overflow of asbestos counting work. Seaford Marshall Lab - Used until ^ 1 1/2 years ago. Haskell Lab - They do well now that they have proper equipment. Martinsville Haskell - Good, but slow! Analytics (Richmond) - Good and fast! Currently using. Kinston Clayton Environmental Consultants - Good Haskell Lab - Used on occasion. Satisfactory (slower turn around and subcontracting some of the samples). Old Hickory Haskell (for identification) - Good Clayton Environmental (for level) - Good Maisco (for level) - Good Clayton and Nalsco used to cross-check on-site analysis. DUP 1013059 DU 053547 Question 4. For each laboratory (on- or off-site), indicate the analytical method used and the level of sensitivity.

Information is available to anybody who wants to see it. (2) If sample is above limit, person exposed is informed in writing as required by law. (3) Only if TLV exceeded and annual summary during the training program. _(4) This is usually done informally. We had one job where the air sample analysis was n, 3.5 fibers/cc, which exceeds the allowance of 2.0 fibers/cc (8 hr. TWA). Therefore, in accordance with policy we formally notified the 5 employees by letter and had them initial/date a copy for the employee's personal folder. Naturally, the letter also pointed out that "they were not over-exposed since they were all wearing respirators. (5) Can be both if sample representative of group. (6) If result exceeds the limit or employee requests the information (or, at Old Hickory, employee's Union representative requests the information). DUP 1013068 DU 053555 Question 10. If employees are notified of analysis results, now is this information transmitted? Cape Fear ~ Written notification. Permanent record for Area personnel file for the individual. Waynesboro By supervisor. Coooer River (1) Through contractor (Industrial Hygiene Data Sheet) (2) Copy to Area (Info transmitted through Shift Log) Chattanooga An Insulator records sample results in file in Insulation Shop. Information is available to anybody who wants to see it. If sample is above limit, person exposed is informed in writing as required by law. Richmond Personally or on bulletin board. Seaford Usually orally by the employee's supervisor. If allowable limit exceeded, employees involved are notified by letter. They initial/date a copy of the letter for their personal folders. Martinsville Copy of Air Sampling Report sent to appropriate supervisor with instructions to inform employee(s) listed of the results and to file a copy of the reoort. Kinston Employees not notified unless result exceeds the limit or employee requests to see the information. Old Hickory If requested by employee or his Union representative, supervisor gives results. If result out of limits, individual(s) notified by letter from immediate supervisor. DUP 1013069 DU 053556 /' V Questions 10 (Continued) v. Camden Supervisor maintains file of sampling/analysis reports. Upon request, information is given to employee. If result ever obtained which exceeds allowable limit, all employees assigned to job will be notified in writing and notification documented in employee's foler, in Area file, in SHEA file, in Medical file. DUP 1013070 DU 053557 Question 11. Are results reviewed by site management? If "yes", how frequently? * Reviewed? Frequency?

Seaford ~ Yes Quarterly Martinsville Yes Monthly Kinston No2 - -- Old Hickory Yes Quarterly Camden Yes Monthly 1 SHEA reviews after each sampling job. : Management notified of out-of-limits data. DUP 1013071 DU 053558 Question 12. List and briefly explain other items pertinent to laboratory analysis for asbestos. Cape Fear Have not completed an in-depth study of the various forms of asbestos present on the site. Waynesboro Cooper River Chattanooga Richmond Seaford Martinsvi11e Are laboratories certified by acceptable agency? Kinston Old Hickory Our devise is TV monitor for counting fibers. Camden DUP 1013072 DU 053559 SUMMARY 2 locations do on-site identity analyses. 1 location (neither of the above) does on-site quantitative analyses; does not send samples off-site for identification. Analytical results from all labs (on- or off-site) rated good to excellent. Response timeTrom Haskell poor; otners o.k. All labs use MIOSH P & CAM 239; detection limit 0.01 fiber/cc. 4 sites have every sample analyzed specifically for asbestos; 5 sites only when AEL exceeded; 1 site selected samples from each job. Response timefor emergency samples varies from 1 day to 30 days; for routine samples from 7 to 30 days. Cost/sample ranges from $25 to $50 for qualitative analysis; $20 to $50 for quantitative analysis. For each sample collected, all sites identify the associated job as involving asbestos or non-asbestos material. 1 site informs all employees of analysis results; all sites inform employees involved with the job in writing if AEL exceeded or if employee (or representative) requests. Employee notification system peculiar to each site. 2 sites review only results > AEL with management; 3 review monthly; 4 quarterly; 1 at least annually. DUP 1013073 DU 053560
