Within thirty days, please supply this office with a written, .item for item description of how each deviation listed in the report was corrected. If the deviations cited in the enclosed report are not corrected, enforcement actions may be recommended. For certification maintenance, your laboratory must continue to meet [the requirements of 15A NCAC 2H .0800. Thank you for your cooperation during the inspection. Contact us at 919-733-3908 if you have questions or need additional information. Sincerely, &17, 4F, esoir,00494 William B. Edwards, Jr. Laboratory Section WBE:jmc Enclosure cc: Norman L.

INTRODUCTION: Alpha Cellulose Corporation P.O. Box 1305 Lumberton, NC 28358 525 July 18, 1996 Maintenance Harvi C. Cooper Eric Bolin and Ronald Radford This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for the analysis of environmental samples. II. GENERAL COMMENTS: Lab is spacious and well equipped. Instruments and facilities are well, maintained. Records are well kept and data looked good. A few minor deviations were found and some further quality control procedures need to be implemented. III. DEVIATIONS, REQUIREMENTS AND COMMENTS: Residual Chlorine Deviation: The daily 0.05 mg/L check standard for Residual Chlorine is often outside the + 10% acceptance criteria. Requirement: The daily mid -range check standard must meet a ± 10% acceptance criteria. Recommend using a 1.0 mg/L check standard. Specific Conductance Deviation: Lab has not documented the required calibration standards for Specific Conductance analyses. Previously Cited. Requirement:. Each day of use, the Conductivity meter :must _be calibrated with a high standard, the cell constant mustbecalculated and the process documented. A low and mid -range standard must also be analyzed and the results documented. Page 2 Alpha Cellulose 1 Comment: Lab has developed a new bench sheet for the calibration records for pH, Conductivity and TDS, but has not documented all of the required standards for Conductivity. Considering the range of concentrations of samples analyzed, it is recommended to use a 10,000 umhos/cm standard in order to bracket sample concentrations as required. Ammonia Deviation: Lab is not documenting the analysis of each group of Ammonia samples. Previously Cited. Requirement: Lab must document the analysis of each group of Ammonia samples. a reagent blank with a leagent blank with Deviation: Lab is currently calibrating the Ammoina Ion Selective electrode with a series of standards from 0.1 mg/L to 100 mg/L. The slope efficiency is below the recommended range of -54 to -60 millivolts for the range of 0.1 to 1.0 mg/L. Requirement: The slope efficiency for the range within which samples are analyzed must be within the manufacturer's recommended range of -54 to -60 millivolts. Comment: Most sample results are <1.0 mg/L. Recommend calibrating with the 0.1 mg/L and 1.0 mg/L in an attempt to increase linearity over a smaller range of concentration. Total Suspended Residue Deviation: Lab is not currently,documenting the performance of multiple drying,desiccating and weighing to establish that samples are at constant weight. Requirement: At least annually, the lab must document the performance of multiple dryings, desiccatings, and weighings to determine that: samples are at constant weight.' ref: Standard Methods 18th Ed. Method 2540 D. (3) (c) pg. 2-56. ,I Deviation: Lab is not documenting the true value or percent recovery of the quarterly check standard. for Total, Suspended Residue. Requirement: Lab must analyze and indicate the true value and percent recovery of a Total Suspended Residue check standard quarterly. ref: 15A NCAC 2H .0805 (a)(7)(B) pg. 6 Deviation: Lab is not documenting the weighing of.3 class S weights quarterly. Page 3 Alpha Cellulose Requirement: Lab must check the analytical balance!by weighing 3 class S weights quarterly and document the results. ref::15A NCAC 2H .0805 (a)(7)(K) pg. 7. General Deviation: Lab is not currently analyzing any s amples in duplicate. Requirement: Lab must analyze samples in duplicate at a frequency of at least 10 % to document precision. ref: 15A NCAC 2H .0805 (a)(7)(C) pg. 6. Deviation: Lab has not documented refrigerator refrigerator log. Previously Cited. temperatures on the Requirement: Lab must record temperatures and initial the temperature log each day of use, for all refrigerators, incubators and ovens.ref: 15A NCAC 2H .0805 (a) (7) (J) pct.7 Comment: Lab has calibrated all of the thermometers against a NIST traceable thermometer, but has done so at approximately 20°C for all thermometers calibrated. A temperature within the range that the individual thermometers are required to operate should be selected for calibration. IV. DATA REVIEW: Data review consisted of a review of the bench sheets and DMR's for. the months of January 1996 thru May 1996. No problems in adhering to required hold times or in properly calculating data were detected. V. CONCLUSION: This lab is doing a good job overall. Personnel contacted were cooperative and competent. Someof the deviations cited in the maintenance inspection on May 24, 1995 remain uncorrected. Since these deviations were cited previously, supporting documentation must be provided to this -office showing the appropriate corrective action. Failure to correct these deviations could result in the loss of method certification, and/or enforcement action. Correction of the above cited deviations should help this lab continue to produce quality data, and meet North Carolinacertification requirements. Report Prepared by: Harvi C.
