1VAC30-45-520. PT criteria for laboratory certification.

A. Result categories.

1. The criteria described in this section apply individually to each PT field of testing, as defined by the laboratory seeking to obtain or maintain certification in its certification request. These criteria apply only to the PT portion of the overall certification standard.

2. There are two PT result categories: "acceptable" and "not acceptable."

B. Initial and continuing certification.

1. A laboratory seeking to obtain or maintain certification shall successfully complete two PT studies for each requested PT field of testing within the most recent three rounds attempted.

2. Once a laboratory has been granted certification status, it shall continue to complete PT studies for each PT field of testing and maintain a history of at least two acceptable PT studies for each PT field of testing out of the most recent three.

3. For a laboratory seeking to obtain initial certification, the most recent three rounds attempted shall have occurred within 18 months of the laboratory's application date.

4. For a laboratory seeking initial certification, or for a laboratory performing supplemental testing, the PT studies shall be at least [ 30 15 ] calendar days apart [ from the closing date of one study to the shipment date of another study for the same PT field of testing ].

5. For a laboratory to maintain certification, completion dates of successive proficiency rounds for a given PT field of testing shall be approximately six months apart. Failure to meet the semiannual schedule is regarded as a failed study.

C. Supplemental studies.

1. A laboratory may elect to participate in PT studies more frequently than required by the semiannual schedule. This may be desirable, for example, when a laboratory first applies for certification or when a laboratory fails a study and wishes to quickly reestablish its history of successful performance.

2. These additional studies shall be reported and are counted and scored the same way as routinely scheduled studies and shall be at least [ 30 15 ] calendar days apart.

D. Failed studies and corrective action.

1. Whenever a laboratory fails a study, it shall determine the cause for the failure and take any necessary corrective action. It shall then document in its own records and provide to DGS-DCLS both the investigation and the action taken.

2. If a laboratory fails two out of the three most recent studies for a given field of testing, its performance is considered unacceptable for that field. The laboratory shall then meet the requirements of initial certification as described in subsection B of this section.

E. Second failed study.

1. The PT provider reports laboratory PT performance results to DGS-DCLS at the same time that it reports the results to the laboratory.

2. If a laboratory fails a second study out of the most recent three, as described in subdivision D 2 of this section, DGS-DCLS shall take action within 60 calendar days to determine the certification status [ of all methods ] for the unacceptable [ analyte or analytes for that program and matrix PT field of testing ].

F. Scheduling of PT studies. [ Laboratories shall determine the schedule for their PT studies. ]

[ 1. DGS-DCLS may specify which months that laboratories within its authority are required to participate in PT study programs.

2. If DGS-DCLS chooses to specify the months, then it shall adhere to the required semiannual schedule. If DGS-DCLS does not specify the months, then the laboratory. ]

G. Withdrawal from PT studies. A laboratory may withdraw from a PT study for an analyte or analytes or for the entire study if the laboratory notifies both the PT provider and DGS-DCLS before the closing date of the PT study. This does not exempt the laboratory from participating in the semiannual schedule.

4. Where test methods are employed that are not required, as in the Performance Based Measurement System approach, the methods shall be fully documented and validated (see subsection E of this section).

E. Demonstration of capability.

1. Prior to acceptance and institution of any test method, satisfactory demonstration of method capability is required. In general, this demonstration does not test the performance of the method in real world samples, but in the applicable and available clean quality system matrix sample (a sample of a quality system matrix in which no target analytes or interferences are present at concentrations that impact the results of a specific test method), e.g., drinking water, solids, biological tissue and air. For analytes that do not lend themselves to spiking, the demonstration of capability may be performed using quality control samples Laboratories shall follow the procedure in subsection F of this section to demonstrate capability.

2. Thereafter, continuing demonstration of method performance, such as laboratory control samples, is required.

3. In cases where a laboratory analyzes samples using a test method that has been in use by the laboratory before July 1999, and there have been no significant changes in instrument type, personnel or test method, the continuing demonstration of method performance and the analyst's documentation of continued proficiency shall be acceptable. The laboratory shall have records on file to demonstrate that an initial demonstration of capability is not required.

4. In all cases, the laboratory shall complete and retain a certification statement shall be completed and retained by the laboratory to be made and shall make the statement available upon request. All The laboratory shall retain all associated supporting data necessary to reproduce the analytical results summarized in the certification statement shall be retained by the laboratory.

5. A The laboratory shall complete a demonstration of capability shall be completed each time there is a change in instrument type, personnel or test method.

6. In laboratories with specialized work cells (a group consisting of analysts with specifically defined tasks that together perform the test method), the group as a unit shall meet the criteria of this subsection. This demonstration of capability shall be fully documented.

F. Procedure for demonstration of capability. 1. The following steps (adapted from the EPA test methods published in 40 CFR Part 136, Appendix A) shall be performed if required reagents/standards are available for mandated test methods. However, before any results are reported using this method, actual sample spike results may be used to meet this standard, i.e., at least four consecutive matrix spikes within the last 12 months. For analytes that do not lend themselves to spiking, e.g., TSS, the demonstration of capability may be performed using quality control samples. The laboratory may document that other approaches to demonstration of capability are adequate. This documentation shall be included in the laboratory's quality manual:

a.1. A quality control (QC) sample shall may be obtained from an outside source . If not available, the QC sample or may be prepared by the laboratory using alternate source stock standards that are prepared independently from those used in instrument calibration.

b. 2. The analyte or analytes shall be diluted in a volume of clean [ quality system ] matrix sufficient to prepare four aliquots at the concentration specified [ , ] or [ , ] if unspecified, to a concentration approximately 10 times the method-stated or laboratory-calculated method detection limit of 1-4 times the limit of quantitation.

c. 3. At least four aliquots shall be prepared and analyzed according to the test method either concurrently or over a period of days.

d. 4. Using all of the results, calculate the mean recovery in the appropriate reporting units (such as g/L) and the standard deviations of the population sample (n-1) (in the same units) for each parameter of interest. When it is not possible to determine mean and standard deviations, such as for presence or absence of the analyte and logarithmic values, the laboratory must shall assess performance against established and documented criteria.

e. 5. Compare the information from subdivision 1 d 4 of this subsection to the corresponding acceptance criteria for precision and accuracy in the test method (if applicable) or in laboratory-generated acceptance criteria (if there are not established mandatory criteria). If all parameters meet the acceptance criteria, the analysis of actual samples may begin. If any one of the parameters do not meet the acceptance criteria, the performance is unacceptable for that parameter.

f. 6. When one or more of the tested parameters fail at least one of the acceptance criteria, the analyst must shall proceed according to either subdivision (1) a or (2) b below.

(1) a. Locate and correct the source of the problem and repeat the test for all parameters of interest beginning with subdivision 1 c 3 of this subsection.

(2) b. Beginning with subdivision 1 c 3 of this subsection, repeat the test for all parameters that failed to meet criteria. Repeated failure, however, confirms a general problem with the measurement system. If this occurs, locate and correct the source of the problem and repeat the test for all compounds of interest beginning with subdivision 1 c 3 of this subsection.

2. It is the responsibility of the laboratory to document that other approaches to demonstrating capability are adequate. This documentation shall be included in the laboratory's quality assurance manual.

1VAC30-45-740. Measurement traceability and calibration.

A. General requirements. All measuring operations and testing equipment used for environmental tests, including equipment for subsidiary measurements (e.g., for environmental conditions) having an a significant effect on the accuracy or validity of tests of the result of the environmental test or sampling shall be calibrated or verified or both before being put into service and on a continuing basis. The laboratory shall have an established program and procedure for the calibration and verification of its measuring and test equipment. This includes balances, thermistors, thermometers and control standards. Such a program shall include a system for selecting, using, calibrating, checking, controlling and maintaining measurement standards, reference materials used as measurement standards, and measuring and test equipment used to perform environmental tests.

B. Traceability of calibration.

1. The laboratory shall ensure that the equipment used can provide the uncertainty of measurement needed.

1. 2. The overall program of calibration or verification or both and validation of equipment shall be designed and operated so as to ensure that measurements made by the laboratory are traceable to national standards of measurement where available.

2. Calibration certificates shall indicate the traceability to national standards of measurement and shall provide the measurement results and associated uncertainty of measurement or a statement of compliance with an identified metrological specification or both. The laboratory shall maintain records of all such certifications.

3. Where traceability of measurements to national standards of measurement the International System of Units (SI) is not applicable the possible or not relevant, the same requirements for traceability to, for example, certified reference materials, agreed methods and/or consensus standards, are required. , the The laboratory shall provide satisfactory evidence of correlation of results, for example by participation in a suitable program of inter-laboratory comparisons, proficiency testing, or independent analysis.

C. Reference standards and reference materials.

1. Reference standards. The laboratory shall have a program and procedure for the calibration of its reference standards. Reference standards of measurement shall be calibrated by a body that can provide traceability as described in subsection B of this section. Such reference standards of measurement held by the laboratory (such as Class S or equivalent weights or traceable thermometers) shall be used for calibration only and for no other purpose, unless it can be demonstrated that their performance as reference standards have would not been be invalidated. Reference standards of measurement shall be calibrated by a body that can provide traceability. Where possible, this traceability shall be to a national standard of measurement Where commercially available, this traceability shall be to a national standard of measurement.

2. There shall be a program of calibration and verification for reference standards.

3. Where relevant, reference standards and measuring and testing equipment shall be subjected to in-service checks between calibrations and verifications. 2. Reference materials. Reference materials shall, where commercially available, be traceable to SI units of measurement, or to certified reference materials. Where possible, traceability shall be to national or international standards of measurement, or to national or international standard reference materials. Internal reference materials shall be checked as far as is technically and economically practicable.

D. Calibration. Calibration requirements are divided into two parts: (i) requirements for analytical support equipment and (ii) requirements for instrument calibration. In addition, the requirements for instrument calibration are divided into initial instrument calibration and continuing instrument calibration verification.

1. Support equipment. These standards apply to all devices that may not be the actual test instrument, but are necessary to support laboratory operations. These include but are not limited to balances, ovens, refrigerators, freezers, incubators, water baths, temperature measuring devices (including thermometers and thermistors), thermal/pressure sample preparation devices and volumetric dispensing devices (such as Eppendorf®, or automatic dilutor or dispensing devices) if quantitative results are dependent on their accuracy, as in standard preparation and dispensing or dilution into a specified volume.

a. All support equipment shall be maintained in proper working order. The records of all repair and maintenance activities, including service calls, shall be kept.

b. All support equipment shall be calibrated or verified at least annually, using NIST traceable references when available, over the entire range of use. The results of such calibration shall be within the specifications required of the application for which this equipment is used. If not, the laboratory shall either (i) remove the equipment from service until repaired or (ii) maintain records of established correction factors to correct all measurements.

c. Raw data records shall be retained to document equipment performance.

d. Prior to use on each working day, balances, ovens, refrigerators, freezers, and water baths shall be checked in the expected use range, with NIST traceable references where available. The acceptability for use or continued use shall be according to the needs of the analysis or application for which the equipment is being used.

e. Mechanical volumetric dispensing devices including burettes (except Class A glassware) shall be checked for accuracy on at least a quarterly use basis. Glass microliter syringes are to be considered in the same manner as Class A glassware, but shall come with a certificate attesting to established accuracy or the accuracy shall be initially demonstrated and documented by the laboratory.

f. For chemical tests, the temperature, cycle time and pressure of each run of autoclaves shall be documented by the use of appropriate chemical indicators or temperature recorders and pressure gauges.

g. For biological tests that employ autoclave sterilization, the following requirements apply:

(1) The performance of each autoclave shall be initially evaluated by establishing its functional properties and performance, for example heat distribution characteristics with respect to typical uses. Autoclaves shall meet specified temperature tolerances. Pressure cookers fitted only with a pressure gauge are not recommended for sterilization of media or decontamination of wastes.

(2) Records of autoclave operations including temperature and time shall be maintained. This shall be done for every cycle. Acceptance and rejection criteria shall be established and used to evaluate the autoclave efficiency and effectiveness.

2. Instrument calibration.

a. This standard specifies the essential elements that define the procedures and documentation for initial instrument calibration and continuing instrument calibration verification to ensure that the data shall be of known quality and be appropriate for a given regulation or decision. This standard does not specify detailed procedural steps for calibration, but establishes the essential elements for selection of the appropriate technique or techniques. If more stringent standards or requirements are included in a mandated test method or by regulation, the laboratory shall demonstrate that such requirements are met. If it is not apparent which standard is more stringent, then the requirements of the regulation or mandated test method are to be followed.

b. Initial instrument calibrations. The following items are essential elements of initial instrument calibration:

(1) The laboratory shall include or reference the details of the initial instrument calibration procedures, including calculations, integrations, acceptance criteria and associated statistics shall be included or referenced in the test method standard operating procedure for the test method. When initial instrument calibration procedures are referenced in the test method, then the laboratory shall retain the referenced material shall be retained by the laboratory and be make it available for review.

(2) Sufficient The laboratory shall retain sufficient raw data records shall be retained to permit reconstruction of the initial instrument calibration, e.g., calibration date, test method, instrument, analysis date, each analyte name, analyst's initials or signature, concentration and response, calibration curve or response factor, or unique equation or coefficient used to reduce instrument responses to concentration.

(3) Sample results shall be quantitated from the initial instrument calibration and may not be quantitated from any continuing instrument calibration verification unless otherwise required by regulation, method, or program.

(4) All initial instrument calibrations shall be verified with a standard obtained from a second manufacturer or lot. Traceability shall be to a national standard, when available. This element does not apply to laboratories performing only simple test procedures.

(5) Criteria for the acceptance of an initial instrument calibration shall be established, e.g., correlation coefficient and relative percent difference. The criteria used shall be appropriate to the technique employed 0.995 or greater for the calibration coefficient unless a different criterion is included in the method being used.

(6) Results of samples not bracketed by initial calibration standards (within calibration range) shall be reported as having less certainty, e.g., defined qualifiers or flags or explained in the case narrative. The lowest calibration standard shall be above the detection limit.

(7) If the initial instrument calibration results are outside established acceptance criteria, corrective actions shall be performed. Data associated with an unacceptable initial instrument calibration shall not be reported.

(8) Calibration standards shall include concentrations at or below the regulatory limit or decision level, if these limits or levels are known by the laboratory, unless these concentrations are below the laboratory's demonstrated detection limits.

(9) If a reference or mandated method does not specify the number of calibration standards, the minimum number is two, not including blanks or a zero standard. The laboratory shall have a standard operating procedure for determining the number of points for establishing the initial instrument calibration.

c. Continuing instrument calibration verification.

(1) When an initial instrument calibration is not performed on the day of analysis, the validity of the initial calibration shall be verified prior to sample analyses by a continuing instrument calibration check with each analytical batch. This provision does not apply to laboratories performing only simple test procedures.

(2) The following items are essential elements of continuing instrument calibration verification:

(a) The laboratory shall include or reference the details of the continuing instrument calibration procedure, calculations and associated statistics shall be included or referenced in the test method standard operating procedure for the test method.

(b) The laboratory shall verify calibration for each compound, element, or other discrete chemical species, except for multicomponent analytes such as Aroclors, Total Petroleum Hydrocarbons, or Toxaphene where a representative chemical related substance or mixture can be used.

(b) A (c) The laboratory shall perform a continuing instrument calibration check shall be repeated at verification as follows:

(i) At the beginning and end of each analytical batch. The concentrations of the calibration verification shall be varied within the established calibration range. If an internal standard is used, only one continuing instrument calibration verification shall be analyzed per analytical batch needs to be performed at the beginning of the analytical batch;

[ (ii) Whenever it is expected that the analytical system may be out of calibration or might not meet the verification acceptance criteria;

(iii) If the time period for calibration or the most previous calibration verification has expired; or

(iv) For analytical systems that contain a calibration verification requirement. ]

(c) (d) Sufficient raw data records shall be retained to permit reconstruction of the continuing instrument calibration verification, e.g., or test method, instrument, analysis date, each analyte name, concentration and response, calibration curve or response factor, or unique equations or coefficients used to convert instrument responses into concentrations. Continuing calibration verification records shall explicitly connect the continuing verification data to the initial instrument calibration.

(d) (e) Criteria for the acceptance of a continuing instrument calibration verification shall be established, e.g., percent recovery or relative percent difference.

(e) (f) If the continuing instrument calibration verification results obtained are outside established acceptance criteria, corrective actions shall be performed. If routine corrective action procedures fail to produce a second consecutive (immediate) calibration verification within acceptance criteria, then either the laboratory has to demonstrate acceptable performance after corrective action with two consecutive successful calibration verifications, or a new initial instrument calibration shall be performed. If the laboratory has not demonstrated acceptable performance verified calibration, sample analyses shall not occur until a new initial calibration curve is established and verified the analytical system is calibrated or calibration verified. However, sample data If samples are analyzed using a system on which the calibration has not yet been verified, the results shall be flagged. Data associated with an unacceptable calibration verification may be reported as qualified data fully useable under the following special conditions:

(i) When the acceptance criteria for the continuing calibration verification are exceeded high, i.e., high bias, and there are associated samples that are nondetects, then those nondetects may be reported. Otherwise the samples affected by the unacceptable calibration verification shall be reanalyzed after a new calibration curve has been established, evaluated and accepted.

(ii) When the acceptance criteria for the continuing calibration verification are exceeded low, i.e., low bias, those sample results may be reported if they exceed a maximum regulatory limit or decision level. Otherwise the samples affected by the unacceptable verification shall be reanalyzed after a new calibration curve has been established, evaluated and accepted.

1VAC30-45-750. Essential quality control procedures Quality assurance.

A. General. The laboratory shall have quality control procedures for monitoring the validity of environmental tests undertaken. The resulting data shall be recorded in such a way that trends are detectable and, where practicable, statistical techniques shall be applied to the reviewing of the results. This monitoring shall be planned and reviewed and may include, but not be limited to, the following:

1. Regular use of certified reference materials and/or internal quality control using secondary reference materials.

2. Participation in interlaboratory comparison or proficiency testing program

3. Replicate tests using the same or different methods.

4. Retesting of retained samples.

5. Correlation of results for different characteristics of a sample (for example, total phosphate should be greater than or equal to orthophosphate).

A. B. Essential quality control procedures. The general quality control principles in subsections B C through E F of this section shall apply, where applicable, to all environmental laboratories. The manner in which they are implemented is dependent on the types of tests performed by the laboratory. 1VAC30-45-760 through 1VAC30-45-829 specify quality control requirements for specific test types. The standards for any given test type shall assure that the applicable principles are addressed.

B. C. All laboratories shall have detailed written protocols in place to monitor the following quality controls:

1. Positive and negative controls to monitor tests such as blanks, spikes, reference toxicants.

2. Tests to define the variability or repeatability of the laboratory results or both such as replicates.

3. Measures to assure the accuracy of the test method including calibration or continuing calibrations or both, use of certified reference materials, proficiency test samples, or other measures.

4. Measures to evaluate test method capability, such as method detection limits and quantitation limits or range of applicability such as linearity.

5. Selection of appropriate formulae to reduce raw data to final results such as regression analysis, comparison to internal and external standard calculations, and statistical analyses.

6. Selection and use of reagents and standards of appropriate quality.

7. Measures to assure the selectivity of the test for its intended purpose.

8. Measures to assure constant and consistent test conditions (both instrumental and environmental) where required by the test method such as temperature, humidity, light, or specific instrument conditions.

C. All quality control measures shall be assessed and evaluated on an on-going basis, and quality control acceptance criteria shall be used to determine the validity of the data.

D. The laboratory shall have procedures for the development of acceptance or rejection criteria where no method or regulatory criteria exist. (See 1VAC30-45-760 B.)

E. The laboratory shall ensure that the essential quality control standards and protocols listed in subsection B of this section and specified by mandated methods or regulations are incorporated into the laboratory's method manual and followed.

1VAC30-45-760. Quality control requirements.

A. General.

1. The quality control protocols specified by the laboratory's method manual shall be followed (1VAC30-45-730 C). The laboratory shall ensure that either the (i) applicable essential standards outlined in this section through 1VAC30-45-829 or (ii) mandated methods or regulations, whichever are more stringent, are incorporated into their method manuals. When it is not apparent which is more stringent, the quality control in the mandated method or regulations is to be followed.

2. All quality control measures shall be assessed and evaluated on an ongoing basis and quality control acceptance criteria shall be used to determine the validity of the data. The laboratory shall have procedures for the development of acceptance/rejection criteria where no method or regulatory criteria exists.

B. Initial test method evaluation. For all test methods other than toxicity and microbiology, the requirements of subdivisions 1 and 2 of this subsection apply. For toxicity and microbiology testing, the initial test method evaluation requirements are contained in 1VAC30-45-780 through 1VAC30-45-788 and 1VAC30-45-790 through 1VAC30-45-798, respectively. For the evaluation of precision and bias (subdivision 3 of this subsection), the requirements of subdivision 3 a of this subsection apply to standard methods. The requirements of subdivision 3 b of this subsection apply to the methods referenced in that subdivision.

1. Limit of detection (LOD).

a. The laboratory shall determine the LOD for the method for each target analyte of concern in the quality system matrices. All sample processing steps of the analytical method shall be included in the determination of the LOD.

b. The validity of the LOD shall be confirmed by qualitative identification of the analyte(s) in a quality control sample in each quality system matrix containing the analyte at no more than two to three times the LOD for single analyte tests and one to four times the LOD for multiple analyte tests. This verification shall be performed on every instrument that is to be used for analysis of samples and reporting of data.

c. An LOD study is not required for any component for which spiking solutions or quality control samples are not available such as temperature, or, when test results are not to be reported to the LOD (versus the limit of quantitation or working range of instrument calibration), according to 1VAC30-45-771, 1VAC30-45-805, 1VAC30-45-814, and 1VAC30-45-826. Where an LOD study is not performed, the laboratory may not report a value below the limit of quantitation.

2. Limit of quantitation (LOQ).

a. The laboratory shall determine the LOQ for each analyte of concern according to a defined, documented procedure.

b. The LOQ study is not required for any component or property for which spiking solutions or quality control samples are not commercially available or otherwise inappropriate (e.g., pH).

c. The validity of the LOQ shall be confirmed by successful analysis of a QC sample containing the analytes of concern in each quality system matrix one to two times the claimed LOQ. A successful analysis is one where the recovery of each analyte is within the established test method acceptance criteria or client data quality objectives for accuracy. This single analysis is not required if the bias and precision of the measurement system is evaluated at the LOQ.

3. Evaluation of precision and bias.

a. Standard methods. The laboratory shall evaluate the precision and bias of a standard method for each analyte of concern for each quality system matrix according to either of the following:

(1) The single-concentration four-replicate recovery study procedures in 1VAC30-45-730 F; or

(2) An alternate procedure documented in the quality manual when the analyte cannot be spiked into the sample matrix and quality control samples are not commercially available.

b. Nonstandard methods.

(1) For laboratory-developed test methods or nonstandard test methods that were not in use by the laboratory before July 2003, the laboratory shall have a documented procedure to evaluate precision and bias. The laboratory shall also compare results of the precision and bias measurements with criteria given in the reference method or criteria established by the laboratory.

(2) Precision and bias measurements shall evaluate the method across the analytical calibration range of the method. The laboratory shall also evaluate precision and bias in the relevant quality system matrices and shall process the samples through the entire measurement system for each analyte of interest.

(3) The following are examples of a systematic approach to evaluate precision and bias:

(a) Example 1. Analyze QC samples in triplicate containing the analytes of concern at or near the limit of quantitation, at the upper-range of the calibration (upper 20%) and at a mid-range concentration. Process these samples on different days as three sets of samples through the entire measurement system for each analyte of interest. Each day one QC sample at each concentration is analyzed. A separate method blank shall be subjected to the analytical method along with the QC samples on each of the three days. (Note that the three samples at the LOQ concentration can demonstrate sensitivity as well.) For each analyte, calculate the mean recovery for each day, for each level over days, and for all nine samples. Calculate the relative standard deviation for each of the separate means obtained. Compare the standard deviations for the different days and the standard deviations for the different concentrations. If the different standard deviations are all statistically insignificant (e.g., F-test), then compare the overall mean and standard deviation with the established criteria from above.

(b) Example 2. A validation protocol such as the Tier I, Tier II, and Tier III requirements in U.S. EPA Office of Water's Alternate Test Procedure (ATP) approval process.

4. Evaluation of selectivity. The laboratory shall evaluate selectivity by following the checks established within the method. These checks may include mass spectral tuning, second column confirmation, ICP inter-element interference checks, chromatography retention time windows, sample blanks, spectrochemical absorption or fluorescence profiles, co-precipitation evaluations, and electrode response factors.

Derived from Virginia Register Volume 25, Issue 7, eff. January 1, 2009.

1VAC30-45-770. Chemical testing: positive and negative controls.

A. Negative control – method performance.

1. Purpose. The method blank is used to assess the preparation batch for possible contamination during the preparation and processing steps. The method blank shall be processed along with and under the same conditions as the associated samples to include all steps of the analytical procedure. Procedures shall be in place to determine if a method blank is contaminated. Any affected samples associated with a contaminated method blank shall be reprocessed for analysis or the results reported with appropriate data qualifying codes.

2. Frequency. The method blank shall be analyzed at a minimum of one per preparation batch. In those instances for which no separate preparation method is used (example: volatiles in water) the batch shall be defined as environmental samples that are analyzed together with the same method and personnel, using the same lots of reagents, not to exceed the analysis of 20 environmental samples.

3. Composition. The method blank shall consist of a quality system matrix that is similar to the associated samples and is known to be free of the analytes of interest.

4. Evaluation criteria and corrective action. While the goal is to have no detectable contaminants, each method blank shall be critically evaluated as to the nature of the interference and the effect on the analysis of each sample within the batch. The source of contamination shall be investigated and measures taken to minimize or eliminate the problem and affected samples reprocessed or data shall be appropriately qualified if:

a. The concentration of a targeted analyte in the blank is at or above the reporting limit as established by the test method or by regulation, and is greater than 1/10 of the amount measured in any sample.

b. The blank contamination otherwise affects the sample results as per the test method requirements or the individual project data quality objectives.

c. When a blank is determined to be contaminated, the cause shall be investigated and measures taken to minimize or eliminate the problem. Samples associated with a contaminated blank shall be evaluated as to the best corrective action for the samples (e.g., reprocessing or data qualifying codes). In all cases the corrective action shall be documented.

B. Positive control – method performance. Laboratory control sample (LCS).

1. Purpose. The LCS is used to evaluate the performance of the total analytical system, including all preparation and analysis steps. Results of the LCS are compared to established criteria and, if found to be outside of these criteria, indicates that the analytical system is "out of control." Any affected samples associated with an out of control LCS shall be reprocessed for re-analysis or the results reported with appropriate data qualifying codes.

2. Frequency. The LCS shall be analyzed at a minimum of one per preparation batch. Exceptions would be for those analytes for which no spiking solutions are available such as total suspended solids, total dissolved solids, total volatile solids, total solids, pH, color, odor, temperature, dissolved oxygen or turbidity. In those instances for which no separate preparation method is used (example: volatiles in water) the batch shall be defined as environmental samples that are analyzed together with the same method and personnel, using the same lots of reagents, not to exceed the analysis of 20 environmental samples.

3. Composition. The LCS is a quality system matrix, known to be free of analytes of interest, spiked with known and verified concentrations of analytes. NOTE: the matrix spike may be used in place of this control as long as the acceptance criteria are as stringent as for the LCS. Alternatively the LCS may consist of a media containing known and verified concentrations of analytes or as Certified Reference Material (CRM). All analyte concentrations shall be within the calibration range of the methods. The following shall be used in choosing components for the spike mixtures:

The components to be spiked shall be as specified by the mandated test method or other regulatory requirement or as requested by the client. In the absence of specified spiking components the laboratory shall spike per the following:

a. For those components that interfere with an accurate assessment such as spiking simultaneously with technical chlordane, toxaphene and PCBs, the spike should be chosen that represents the chemistries and elution patterns of the components to be reported.

b. For those test methods that have extremely long lists of analytes, a representative number may be chosen. The analytes selected should be representative of all analytes reported. The following criteria shall be used for determining the minimum number of analytes to be spiked. However, the laboratory shall insure that all targeted components are included in the spike mixture over a two-year period. For methods that include 1-10 targets, spike all components; for methods that include 11-20 targets, spike at least 10% or 80%, whichever is greater; and for methods with more than 20 targets, spike at least 16 components.

4. Evaluation criteria and corrective action.

a. The results of the individual batch LCS are calculated in percent recovery or other appropriate statistical technique that allows comparison to established acceptance criteria. The laboratory shall document the calculation.

b. The individual LCS is compared to the acceptance criteria as published in the mandated test method. Where there are no established criteria, the laboratory shall determine internal criteria and document the method used to establish the limits or utilize client specified assessment criteria.

c. A LCS that is determined to be within the criteria effectively establishes that the analytical system is in control and validates system performance for the samples in the associated batch. Samples analyzed along with a LCS determined to be "out of control" shall be considered suspect and the samples reprocessed and re-analyzed or the data reported with appropriate data qualifying codes.

5. If a large number of analytes are in the LCS, it becomes statistically likely that a few will be outside control limits. This may not indicate that the system is out of control, therefore corrective action may not be necessary. Upper and lower marginal exceedance (ME) limits can be established to determine when corrective action is necessary. A ME is defined as being beyond the LCS control limit (3 standard deviations), but within the ME limits. ME limits are between 3 and 4 standard deviations around the mean.

a. The number of allowable marginal exceedances is based on the number of analytes in the LCS. If more analytes exceed the LCS control limits than is allowed, or if any one analyte exceeds the ME limits, the LCS fails and corrective action is necessary. This marginal exceedance approach is relevant for methods with long lists of analytes. It will not apply to target analyte lists with fewer than 11 analytes.

b. The number of allowable marginal exceedances is as follows:

c. Marginal exceedances shall be random. If the same analyte exceeds the LCS control limit repeatedly, it is an indication of a systemic problem. The source of the error shall be located and corrective action taken. Laboratories shall have a written procedure to monitor the application of marginal exceedance allowance to the LCS to ensure random behavior.

C. Sample specific controls - general.

1. The laboratory shall document procedures for determining the effect of the sample matrix on method performance. These procedures relate to the analyses of quality system matrix specific Quality Control (QC) samples and are designed as data quality indicators for a specific sample using the designated test method. These controls alone are not used to judge laboratory performance.

2. Examples of matrix specific QC include: Matrix Spike (MS); Matrix Spike Duplicate (MSD); sample duplicates; and surrogate spikes. The laboratory shall have procedures in place for tracking, managing, and handling matrix specific QC criteria including spiking appropriate components at appropriate concentrations, calculating recoveries and relative percent difference, evaluating and reporting results based on performance of the QC samples.

D. Sample specific controls - matrix spike and matrix spike duplicates.

1. Purpose. Matrix specific QC samples indicate the effect of the sample matrix on the precision and accuracy of the results generated using the selected method. The information from these controls is sample/matrix specific and would not normally be used to determine the validity of the entire batch.

2. Frequency. The frequency of the analysis of matrix specific samples shall be determined as part of a systematic planning process (e.g., Data Quality Objectives) or as specified by the test method.

3. Composition. The components to be spiked shall be as specified by the mandated test method. Any permit specified analytes, as specified by regulation or client requested analytes shall also be included. If there are no specified components, the laboratory shall spike per the following:

a. For those components that interfere with an accurate assessment such as spiking simultaneously with technical chlordane, toxaphene and PCBs, the spike should be chosen that represents the chemistries and elution patterns of the components to be reported.

b. For those test methods that have extremely long lists of analytes, a representative number may be chosen using the following criteria for choosing the number of analytes to be spiked. However, the laboratory shall insure that all targeted components are included in the spike mixture over a two-year period.

(1) For methods that include 1-10 targets, spike all components;

(2) For methods that include 11-20 targets, spike at least 10% or 80%, whichever is greater;

(3) For methods with more than 20 targets, spike at least 16 components.

4. Evaluation criteria and corrective action.

a. The results from matrix spike/matrix spike duplicate are primarily designed to assess the precision and accuracy of analytical results in a given matrix and are expressed as percent recovery (%R), relative percent difference (RPD), or other appropriate statistical technique that allows comparison to established acceptance criteria. The laboratory shall document the calculation for %R, RPD or other statistical treatment used.

b. The results are compared to the acceptance criteria as published in the mandated test method. Where there are no established criteria, the laboratory shall determine internal criteria and document the method used to establish the limits. For matrix spike results outside established criteria corrective action shall be documented or the data reported with appropriate data qualifying codes.

E. Sample specific controls - matrix duplicates.

1. Purpose. Matrix duplicates are defined as replicate aliquots of the same sample taken through the entire analytical procedure. The results from this analysis indicate the precision of the results for the specific sample using the selected method. The matrix duplicate provides a usable measure of precision only when target analytes are found in the sample chosen for duplication.

2. Frequency. The frequency of the analysis of matrix duplicates may be determined as part of a systematic planning process (e.g., Data Quality Objectives) or as specified by the mandated test method.

3. Composition. Matrix duplicates are performed on replicate aliquots of actual samples. The composition is usually not known.

4. Evaluation criteria and corrective action.

a. The results from matrix duplicates are primarily designed to assess the precision of analytical results in a given matrix and are expressed as relative percent difference (RPD) or another statistical treatment (e.g., absolute differences). The laboratory shall document the calculation for relative percent difference or other statistical treatments.

b. Results are compared to the acceptance criteria as published in the mandated test method. Where there are no established criteria, the laboratory shall determine internal criteria and document the method used to establish the limits. For matrix duplicates results outside established criteria corrective action shall be documented or the data reported with appropriate data qualifying codes.

F. Sample specific controls - surrogate spikes.

1. Purpose. Surrogates are used most often in organic chromatography test methods and are chosen to reflect the chemistries of the targeted components of the method. Added prior to sample preparation/extraction, they provide a measure of recovery for every sample matrix.

2. Frequency. Except where the matrix precludes its use or when not commercially available, surrogate compounds shall be added to all samples, standards, and blanks for all appropriate test methods.

3. Composition. Surrogate compounds are chosen to represent the various chemistries of the target analytes in the method or MQO. They are often specified by the mandated method and are deliberately chosen for their being unlikely to occur as an environmental contaminant. Often this is accomplished by using deuterated analogs of select compounds.

4. Evaluation criteria and corrective action. The results are compared to the acceptance criteria as published in the mandated test method. Where there are no established criteria, the laboratory should determine internal criteria and document the method used to establish the limits. Surrogates outside the acceptance criteria shall be evaluated for the effect indicated for the individual sample results. Data quality objectives or other site-specific requirements may guide the appropriate corrective action. Results reported from analyses with surrogate recoveries outside the acceptance criteria should include appropriate data qualifiers.

Statutory Authority

§ 2.2-1105 of the Code of Virginia.

Historical Notes

Derived from Virginia Register Volume 25, Issue 7, eff. January 1, 2009.

1VAC30-45-781. Toxicity testing: positive and negative controls.

A. Positive control. Reference toxicant tests demonstrate a laboratory's ability to obtain consistent results with the test method and evaluate the overall health and sensitivity of test organisms over time.

1. The laboratory shall demonstrate its ability to obtain consistent results with standard reference toxicants (SRT) and complete an initial Demonstration of Capability (DOC) in order to attain accreditation in toxicity testing methods.

a. An initial DOC shall consist of five or more acceptable SRT tests for each test method, species and endpoint with different batches of organisms. Appropriate negative controls (water, sediment, or soil) shall be tested at the frequency and duration specified in the test method. Initial DOCs shall be prepared in accordance with the requirements of 1VAC30-45-730 F.

b. Initial DOC is established by maintenance of SRT test results on control charts. A laboratory shall record the control performance and statistical endpoints (such as NOEC or ECp) for each method species and endpoint on control charts. Initial DOC is established where 95% of the test results required in subdivision A 1 a of this section fall within the control limits established in accordance with subdivision A 1 c of this section and meet test acceptability criteria (TAC). The laboratory shall evaluate precision (i.e., coefficient of variation (CV)) or sensitivity (i.e., statistical minimum significant difference (SMSD) measures; see subdivision A 1 d of this section) for these tests against method-specific or, lacking the former, laboratory-derived criteria to determine validity of the initial DOC.

c. For endpoints that are point estimates (ICp, ECp), control charts are constructed by plotting the cumulative mean and the control limits that consist of the upper and lower 95% confidence limits (+/- 2 standard deviations). In case of highly variable point estimates that exceed method-specific criteria, the control chart limits are adjusted accordingly. For endpoints from hypothesis tests (NOEC, NOAEC), the values are plotted directly and the control limits consist of one concentration interval above and below the concentration representing the central tendency (i.e., the mode).

d. For endpoints that are point estimates, the cumulative mean CV is calculated and for endpoints from hypothesis tests, the SMSD is calculated. These values are maintained on a control chart.

2. Ongoing laboratory performance shall be demonstrated by routine SRT testing for each test method and species and endpoint in accordance with the minimum frequency requirements specified in subdivision A 3 of this section.

a. Intralaboratory precision is determined on an ongoing basis through the use of control charts as established in subdivision A 1 b of this section. The control charts shall be plotted as point estimate values, such as EC25 for chronic tests and LC50 for acute tests, or as appropriate hypothesis test values, such as the NOEC or NOAEC, over time within a laboratory.

b. After initial laboratory DOC is determined, the control limits and CV for an individual test method, endpoints and species shall be adjusted as additional test results are obtained. After 20 data points are collected for a test method and species, the control chart is maintained using only the last 20 data points, i.e., each successive mean value and control limit is calculated using only the last 20 values.

c. Control chart limits are expected to be exceeded occasionally regardless of how well a laboratory performs. Acceptance limits for point estimates (ICp, ECp) that are based on 95% confidence limits should theoretically be exceeded for one in 20 tests. Depending on the dilution factor and test sensitivity, control charts based on hypothesis test values (NOEC, NOAEC) may be expected to be exceeded on a similar frequency. Test results that fall outside of control chart limits at a frequency of 5.0% or less, or that fall just outside control chart limits (especially in the case of highly proficient laboratories that may develop relatively narrow acceptance limits over time), are not rejected de facto. Such data are evaluated in comparison with control chart characteristics including the width of the acceptance limits and the degree of departure of the value from acceptance limits.

d. Consistent with the test methods used, laboratories shall develop acceptance/rejection policies for SRT data that consider the source of test organisms, the direction of the deviation, test dilution factor, test sensitivity (for hypothesis test values), testing frequency, out-of-control test frequency, relative width of acceptance limits, inter-test CV, and degree of difference between test results and acceptance limits.

e. In the case of reference toxicant data that fails to meet control chart acceptance criteria, the test data are examined for defects, corrective action taken, and the test repeated if necessary, using a different batch of organisms or the data is qualified.

3. The frequency of ongoing laboratory reference toxicant testing shall be as follows unless the method specifically requires less frequent SRT tests (e.g., sediment tests):

a. For test methods conducted at a frequency of monthly or greater, SRT tests shall be conducted at an ongoing frequency of monthly.

b. For test methods and species commonly used in the laboratory, but that are tested at a frequency of less than monthly, SRT tests shall be conducted concurrently with the environmental test.

c. If the test organisms are obtained from an outside source the sensitivity of each batch of organisms received from a supplier shall be determined via a concurrent SRT test unless the supplier can provide control chart data for the last five SRT tests using the same SRT and test conditions. Supplied SRT data may not be older than six months.

d. The DOC for an analyst shall be consistent with 1VAC30-45-220 B but the frequency need not exceed the method-specified requirements and subdivision A 3 a and A 3 b of this section.

4. These standards do not currently specify a particular reference toxicant and dilution series. If the permitting authority identifies a reference toxicant or dilution series for a particular test, the laboratory shall follow the specified requirements. All reference toxicant tests conducted for a given test method and species shall use the same reference toxicant, test concentrations, dilution water and data analysis methods. A dilution factor of 0.5x or greater shall be used for both acute and chronic tests.

5. The reference toxicant tests shall be conducted following the same procedures as the environmental toxicity tests for which the precision is being evaluated, unless otherwise specified in the test method (for example, 10-day sediment tests employ 96-h water-only reference toxicant tests). The test duration, laboratory dilution water, feeding, organism age, range and density, test volumes, renewal frequency, water quality measurements, and the number of test concentrations, replicates and organisms per replicate shall be the same as specified for the environmental toxicity test.

B. Negative control: control, brine control, control sediment, control soil or dilution water.

1. The standards for the use, type and frequency of testing of negative controls are specified by the test methods and by permit or regulation and shall be followed. A negative control is included with each test to evaluate test performance and the health and sensitivity of the specific batch of organisms.

2. Appropriate additional negative controls shall be included when sample adjustments (for example, addition of thiosulfate for dechlorination) or solvent carriers are used in the test.

3. Test acceptability criteria (TAC). The test acceptability criteria specified in the test method shall be achieved for both the reference toxicant and the effluent or environmental sample toxicity test. The criteria shall be calculated and shall meet the method specified requirements for performing toxicity tests.

1VAC30-45-788. Toxicity testing: constant and consistent test conditions.

A. If closed refrigerator‑sized incubators are used, culturing and testing of organisms shall be separated to avoid cross‑contamination.

B. Laboratory space shall be adequate for the types and numbers of tests performed. The building shall provide adequate cooling, heating and illumination for conducting testing and culturing; hot and cold running water shall be available for cleaning equipment.

C. Air used for aeration of test solutions, dilution waters and cultures shall be free of oil and fumes.

D. The laboratory or a contracted outside expert shall positively identify test organisms to species on an annual basis. The taxonomic reference (citation and page(s)) and the names(s) of the taxonomic expert(s) shall be kept on file at the laboratory. When organisms are obtained from an outside source, the supplier shall provide this same information.

E. Instruments used for routine support measurements of chemical and physical parameters such as pH, DO, conductivity, salinity, alkalinity, hardness, chlorine, ammonia, and weight shall be calibrated, and/or standardized per manufacturer's instructions. As these are support measurements, only the calibration and verification requirements specified at 1VAC30-45-740 D 1 apply. All measurements and calibrations shall be documented.

F. Test temperature shall be maintained as specified for the test method. Temperature control equipment shall be adequate to maintain the required test temperature(s). The average daily temperature of the test solutions shall be maintained within the method-specified range. The minimum frequency of measurement shall be once per 24-hour period. The test temperature for continuous-flow toxicity tests shall be recorded and monitored continuously. Where electronic data loggers are used, temperature shall be monitored at a frequency sufficient to capture temporal variations of the environmental control system.

G. Reagent-grade water, prepared by any combination of distillation, reverse osmosis, ion exchange, activated carbon and particle filtration, shall meet the method specified requirements.

H. The quality of the standard dilution water used for testing or culturing shall be sufficient to allow satisfactory survival, growth and reproduction of the test species as demonstrated by routine reference toxicant tests and negative control performance. Water used for culturing and testing shall be analyzed for toxic metals and organics whenever the minimum acceptability criteria for control survival, growth or reproduction are not met and no other cause, such as contaminated glassware or poor stock, can be identified. It is recognized that the analyte lists of some methods manuals may not include all potential toxicants, are based on estimates of chemical toxicity available at the time of publication and may specify detection limits that are not achievable in all matrices. However, for those analytes not listed, or for which the measured concentration or limit of detection is greater than the method-specified limit, the laboratory shall demonstrate that the analyte at the measured concentration or reported limit of detection does not exceed one-tenth of the expected chronic value for the most sensitive species tested and/or cultured. The expected chronic value is based on professional judgment and the best available scientific data. The "USEPA Ambient Water Quality Criteria Documents" and the EPA AQUIRE database provide guidance and data on acceptability and toxicity of individual metals and organic compounds.

I. The quality of the food used for testing or culturing shall be sufficient to allow satisfactory survival, growth and reproduction of the test species as demonstrated by routine reference toxicant tests and negative control performance. The laboratory shall have written procedures for the evaluation of food acceptance.

J. A subset of organisms used in bioaccumulation tests shall be analyzed at the start of the test (baseline) for the target compounds to be measured in the bioaccumulation tests.

K. Test chamber size and test solution volume shall be as specified in the test method. All test chambers used in a test shall be identical.

L. Test organisms shall be fed the quantity and type food or nutrients specified in the test method. They shall also be fed at the intervals specified in the test methods.

M. All organisms in a test shall be from the same source. Where available certified seeds are used for soil tests.

N. All organisms used in tests, or used as broodstock to produce neonate test organisms (for example cladocerans and larval fish), shall appear healthy, show no signs of stress or disease and exhibit acceptable survival (90% or greater) during the 24-hour period immediately preceding use in tests.

O. All materials used for test chambers, culture tanks, tubing, etc., and coming in contact with test samples, solutions, control water, sediment or soil or food shall be nontoxic and cleaned as described in the test methods. Materials shall not reduce or add to sample toxicity. Appropriate materials for use in toxicity testing and culturing are described in the referenced manuals.

P. Light intensity shall be maintained as specified in the methods manuals. Measurements shall be made and recorded on a yearly basis. Photoperiod shall be maintained as specified in the test methods and shall be documented at least quarterly. For algal and plant tests, the light intensity shall be measured and recorded at the start of each test.

Q. The testing laboratory shall document the health and culturing conditions of all organisms used for testing. Such documentation shall include culture conditions (e.g., salinity, hardness, temperature, pH) and observations of any stress, disease or mortality. When organisms are obtained from an outside source, the laboratory shall obtain written documentation of these water quality parameters and biological observations for each lot of organism received. These observations shall adequately address the 24-hour time period referenced in subsection N of this section. The laboratory shall also record each of these observations and water quality parameters upon the arrival of the organisms at the testing laboratory.

R. Age and the age range of the test organisms shall be as specified in the test method. Supporting information, such as hatch dates and times, times of brood releases and metrics (for example, chironomid head capsule width) shall be documented.

S. The maximum holding time of effluents (elapsed time from sample collection to first use in a test) shall not exceed 36 hours; samples may be used for renewal up to 72 hours after first use except as prescribed by the method and approved by the regulatory agency having authority for program oversight.

T. All samples shall be chilled to 0 to 6°C during or immediately after collection except as prescribed by the method.

U. Organisms used in a given test shall be from the same batch.

V. All tests shall have the minimum number of replicates per treatment as prescribed by the method.

W. The control population of Ceriodaphnia in chronic effluent or receiving water tests shall contain no more than 20% males.

X. The culturing of C. dubia shall be adequate such that blocking by parentage can be established.

Y. Dissolved oxygen and pH in aquatic tests shall be within acceptable range at test initiation and aeration (minimal) is provided to tests if, and only if, acceptable dissolved oxygen concentrations cannot be otherwise maintained or if specified by the test method.

Z. Test soils or sediments shall be within the geochemical tolerance range of the test organism.

AA. An individual test may be conditionally acceptable if temperature, dissolved oxygen, pH and other specified conditions fall outside specifications, depending on the degree of the departure and the objectives of the tests (see test conditions and test acceptability criteria specified for each test method).

1VAC30-45-791. Microbiology testing: sterility checks and blanks, positive and negative controls.

A. Sterility checks and blanks. The laboratory shall demonstrate that the filtration equipment and filters, sample containers, media and reagents have not been contaminated through improper handling or preparation, inadequate sterilization, or environmental exposure.

1. A sterility blank shall be analyzed for each lot of pre-prepared, ready-to-use medium (including chromofluorogenic reagent) and for each batch of medium prepared in the laboratory. This shall be done prior to first use of the medium.

2. For filtration technique, the laboratory shall conduct one beginning and one ending sterility check for each laboratory sterilized filtration unit used in a filtration series. The filtration series may include single or multiple filtration units, which have been sterilized prior to beginning the series. For presterilized single use funnels a sterility check shall be performed on one funnel per lot. The filtration series is considered ended when more than 30 minutes elapses between successive filtrations. During a filtration series, filter funnels shall be rinsed with three 20-30 ml portions of sterile rinse water after each sample filtration. In addition, laboratories shall insert a sterility blank after every 10 samples or sanitize filtration units by UV light after each sample filtration.

3. For pour plate technique, sterility blanks of the medium shall be made by pouring, at a minimum, one uninoculated plate for each lot of pre-prepared, ready-to-use media and for each batch of medium prepared in the laboratory.

4. Sterility checks on sample containers shall be performed on at least one container for each lot of purchased, presterilized containers. For containers prepared and sterilized in the laboratory, a sterility check shall be performed on one container per sterilized batch with nonselective growth media.

5. A sterility blank shall be performed on each batch of dilution water prepared in the laboratory and on each batch of pre-prepared, ready-to-use dilution water with nonselective growth media.

6. At least one filter from each new lot of membrane filters shall be checked for sterility with nonselective growth media.

B. Positive controls.

1. Positive culture controls demonstrate that the medium can support the growth of the target organism(s), and that the medium produces the specified or expected reaction to the target organism(s).

2. Each preprepared, ready-to-use lot of medium (including chromofluorogenic reagent) and each batch of medium prepared in the laboratory shall be tested and demonstrate a known positive response. This shall be done prior to first use of the medium.

C. Negative controls. The provisions of this subsection shall not apply to wastewater treatment plants.

1. Negative culture controls demonstrate that the medium does not support the growth of non-target organisms or does not demonstrate the typical positive reaction of the target organism(s).

2. Each pre-prepared, ready-to-use lot of selective medium (including chromofluorogenic reagent) and each batch of selective medium prepared in the laboratory shall be analyzed with one or more known negative culture controls, i.e., nontarget organisms, as appropriate to the method. This shall be done prior to first use of the medium.

1VAC30-45-801. Radiochemical testing: negative and positive controls.

A. Negative controls.

1. Method blank shall be performed at a frequency of one per preparation batch. The results of this analysis shall be one of the quality control measures to be used to assess the batch. The method blank result shall be assessed against the specific acceptance criteria specified in the laboratory method manual. When the specified method blank acceptance criteria is not met, the specified corrective action and contingencies shall be followed and results reported with appropriate data qualifying codes. The occurrence of a failed method blank acceptance criteria and the actions taken shall be noted in the laboratory report.

2. In the case of gamma spectrometry, generally a nondestructive analysis, a method blank shall be prepared using a calibrated counting geometry similar to that used for the samples. The container of the appropriate geometry can be empty or filled to similar volume to partially simulate gamma attenuation due to a sample matrix.

3. There shall be no subtraction of the required method blank result from the sample results in the associated preparation or analytical batch unless permitted by method or program. This does not preclude the application of any correction factor (e.g., instrument background, analyte presence in tracer, reagent impurities, peak overlap, etc.) to all analyzed samples, both program/project submitted and internal quality control samples. However, these correction factors shall not depend on the required method blank result in the associated analytical batch.

4. The method blank sample shall be prepared with similar aliquot size to that of the routine samples for analysis and the method blank result and acceptance criteria shall be calculated in a manner that compensates for sample results based upon differing aliquot size.

B. Positive controls.

1. Laboratory control samples shall be performed at a frequency of one per preparation batch. The results of this analysis shall be one of the quality control measures to be used to assess the batch. The laboratory control sample result shall be assessed against the specific acceptance criteria specified in the laboratory method manual. When the specified laboratory control sample acceptance criteria is not met the specified corrective action and contingencies shall be followed. The occurrence of a failed laboratory control sample acceptance criteria and the actions taken shall be noted in the laboratory report.

2. Matrix spike shall be performed at a frequency of one per preparation batch for those methods that include a chemical separation process without the use of an internal standard or carrier, and where there is sufficient sample to do so. Although gross alpha, gross beta and tritium measurements do not involve a chemical separation process, matrix spikes shall be performed for these analyses on aqueous samples. The results of this analysis shall be one of the quality control measures to be used to assess the batch. The matrix spike result shall be assessed against the specific acceptance criteria specified in the laboratory method manual. When the specified matrix spike acceptance criteria is not met, the specified corrective action and contingencies shall be followed. The occurrence of a failed matrix spike acceptance criteria and the actions taken shall be noted in the laboratory report. The lack of sufficient sample aliquot size to perform a matrix spike shall be noted in the laboratory report.

3. The activity of the laboratory control sample shall (i) be at least five times the limit of detection and (ii) at a level comparable to that of routine samples when such information is available if the sample activities are expected to exceed five times the limit of detection.

4. The activity of the matrix spike analytes(s) shall be greater than five times the limit of detection.

5. The laboratory standards used to prepare the laboratory control sample and matrix spike shall be from a source independent of the laboratory standards used for instrument calibration and shall meet the requirements for reference standards provided in 1VAC30-45-807 A.

6. The matrix spike shall be prepared by adding a known activity of target analyte after subsampling if required but before any chemical treatment (e.g., chemical digestion, dissolution, separation, etc.). Where a radiochemical method, other than gamma spectroscopy, has more than one reportable analyte isotope (e.g., plutonium, Pu 238 and Pu 239, using alpha spectrometry), only one of the analyte isotopes need be included in the laboratory control or matrix spike sample at the indicated activity level. However, where more than one analyte isotope is present above the specified limit of detection, each shall be assessed against the specified acceptance criteria.

7. Where gamma spectrometry is used to identify and quantitate more than one analyte isotope, the laboratory control sample shall contain isotopes that represent the low (e.g., americium-241), medium (e.g., cesium-137) and high (e.g., cobalt-60) energy range of the analyzed gamma spectra. As indicated by these examples the isotopes need not exactly bracket the calibrated energy range or the range over which isotopes are identified and quantitated.

8. The laboratory control sample shall be prepared with similar aliquot size to that of the routine samples for analyses.

C. Other controls.

1. Tracer. For those methods that utilize a tracer (i.e., internal standard) each sample result shall have an associated tracer recovery calculated and reported. The tracer shall be added to the sample after subsampling if required but before any chemical treatment (e.g., chemical digestion, dissolution, separation, etc.) unless otherwise specified by the method. The tracer recovery for each sample result shall be one of the quality control measures to be used to assess the associated sample result acceptance. The tracer recovery shall be assessed against the specific acceptance criteria specified in the laboratory method manual. When the specified tracer recovery acceptance criteria is not met the specified corrective action and contingencies shall be followed. The occurrence of a failed tracer recovery acceptance criteria and the actions taken shall be noted in the laboratory report.

2. Carrier. For those methods that utilize a carrier for recovery determination, each sample shall have an associated carrier recovery calculated and reported. The carrier shall be added to the sample after subsampling if required but before any chemical treatment (e.g., chemical digestion, dissolution, separation, etc.) unless otherwise specified by the method. The carrier recovery for each sample shall be one of the quality control measures to be used to assess the associated sample result acceptance. The carrier recovery shall be assessed against the specific acceptance criteria specified in the laboratory method manual. When the specified carrier recovery acceptance criteria is not met the specified corrective action and contingencies shall be followed. The occurrence of a failed carrier recovery acceptance criteria and the actions taken shall be noted in the laboratory report.

1VAC30-45-804. Radiochemical testing: radiation measurement instrumentation.

A. General. Because of the stability and response nature of modern radiation measurement instrumentation, it is not typically necessary to verify calibrate these systems each day of use. However, verification of calibration is required as outlined in subsection B of this section. This section addresses those practices that are necessary for proper calibration and those requirements of 1VAC30-45-740 D (instrument calibrations) that are not applicable to some types of radiation measurement instrumentation.

B. Instrument calibration.

1. Given that activity detection efficiency is independent of sample activity at all but extreme activity levels, the requirements of 1VAC30-45-740 D 2 b (7) are not applicable to radiochemical method calibrations except mass attenuation in gas-proportional counting and sample quench in liquid scintillation counting. Radiation measurement instruments are subject to calibration prior to initial use, when the instrument is placed back in service after malfunctioning and the instrument's response has changed as determined by a performance check or when the instrument's response exceeds predetermined acceptance criteria for the instrument quality control.

2. Instrument calibration shall be performed with reference standards as defined in 1VAC30-45-807 A. The standards shall have the same general characteristics (i.e., geometry, homogeneity, density, etc.) as the associated samples.

3. The frequency of calibration shall be addressed in the laboratory method manual if not specified in the method. A specific frequency (e.g., monthly) or observations from the associated control or tolerance chart, as the basis for calibration shall be specified.

C. Continuing instrument calibration verification (performance checks). Performance checks shall be performed using appropriate check sources and monitored with control charts or tolerance charts to ensure that the instrument is operating properly and that the detector response has not significantly changed and, therefore, the instrument calibration has not changed. The same check source used in the preparation of the tolerance chart or control chart at the time of calibration shall be used in the calibration verification of the instrument. The check sources shall provide adequate counting statistics for a relatively short count time and the source should be sealed or encapsulated to prevent loss of activity and contamination of the instrument and laboratory personnel.

1. For gamma spectroscopy systems, the performance checks for efficiency and energy calibration shall be performed on a day-of-use basis along with performance checks on peak resolution.

2. For alpha spectroscopy systems, the performance check for energy calibration shall be performed on a weekly basis and the performance check for counting efficiency shall be performed on at least a monthly basis.

3. For gas-proportional and liquid scintillation counters, the performance check for counting efficiency shall be performed on a day-of-use basis. For batches of samples that uninterruptedly count for more than a day a performance check can be performed at the beginning and end of the batch as long as this time interval is no greater than one week. Verification of instrument calibration does not directly verify secondary calibrations, e.g., the mass efficiency curve or the quench curve.

4. For scintillation counters the calibration verification for counting efficiency shall be performed on a day of use basis.

D. Background measurement. Background measurements shall be made on a regular basis and monitored using control charts or tolerance charts to ensure that a laboratory maintains its capability to meet required data quality objectives. These values may be subtracted from the total measured activity in the determination of the sample activity.

1. For gamma spectroscopy systems, background measurements shall be performed on at least a monthly basis.

2. For alpha spectroscopy systems, background measurements shall be performed on at least a monthly basis.

3. For gas-proportional counters, background measurements shall be performed on at least on a weekly basis.

4. For scintillation counters, background measurements shall be performed each day of use.

E. Instrument contamination monitoring. The laboratory shall have a written procedure for monitoring radiation measurement instrumentation for radioactive contamination. The procedure shall indicate the frequency of the monitoring and shall indicate criteria, which initiates corrective action.

2. Reference standards shall be accompanied with a certificate of calibration whose content is as described in ANSI N42.22 - 1995, Section 8, Certificates.

3. Laboratories should consult with the supplier if the laboratory's verification of the activity of the reference traceable standard indicates a noticeable deviation from the certified value. The laboratory shall not use a value other than the decay corrected certified value.

The results of the method blank analysis shall be used to evaluate the contribution of the laboratory provided sampling media and analytical sample preparation procedures to the amount of analyte found in each sample. If the method blank result is greater than the limit of quantitation and contributes greater than 10% of the total amount of analyte found in the sample, the source of the contamination shall be investigated and measures taken to eliminate the source of contamination. If contamination is found, the data shall be qualified in the report.

c. The laboratory should have a set of reference asbestos materials from which a set of reference diffraction and X-ray spectra have been developed.

B. Phase contrast microscopy. At least two field blanks (or 10% of the total samples, whichever is greater) shall be submitted for analysis with each set of samples. Field blanks shall be handled in a manner representative of actual handling of associated samples in the set with a single exception that air shall not be drawn through the blank sample. A blank cassette shall be opened for approximately 30 seconds at the same time other cassettes are opened just prior to analysis. Results from field blank samples shall be used in the calculation to determine final airborne fiber concentration. The identity of blank filters should be unknown to the counter until all counts have been completed. If a field blank yields greater than seven fibers per 100 graticule fields, report possible contamination of the samples.

C. Polarized light microscopy.

1. Friable materials. At least one blank slide shall be prepared daily or with every 50 samples analyzed, whichever is less. This is prepared by mounting a subsample of an isotropic verified non-ACM (e.g., fiberglass in SRM 1866) in a drop of immersion oil (n_D should reflect usage of various n_D's) on a clean slide, rubbing preparation tools (forceps, dissecting needles, etc.) in the mount and placing a clean coverslip on the drop. The entire area under the coverslip shall be scanned to detect any asbestos contamination. A similar check shall be made after every 20 uses of each piece of homogenization equipment. An isotropic verified non-ACM shall be homogenized in the clean equipment, a slide prepared with the material and the slide scanned for asbestos contamination. (This can be substituted for the blank slide mentioned in this section.)

2. Nonfriable materials. At least one non-ACM nonfriable material shall be prepared and analyzed with every 20 samples analyzed. This non-ACM shall go through the full preparation and analysis regimen for the type of analysis being performed.

1VAC30-45-822. Asbestos testing: test variability/reproducibility.

A. Transmission electron microscopy. Quality assurance analyses shall be performed regularly covering all time periods, instruments, tasks, and personnel. The selection of samples shall be random and samples of special interest may be included in the selection of samples for quality assurance analyses. When possible, the checks on personnel performance shall be executed without their prior knowledge. A disproportionate number of analyses shall not be performed prior to internal or external audits. It is recommended that a laboratory initially be at 100% quality control (all samples reanalyzed). The proportion of quality control samples can later be lowered gradually, as control indicates, to a minimum of 10%.

1. Water and wastewater. All analyses shall be performed on relocator grids so that other laboratories can easily repeat analyses on the same grid openings. Quality assurance analyses shall not be postponed during periods of heavy workloads. The total number of QA samples and blanks shall be greater than or equal to 10% of the total sample workload. Precision of analyses is related to concentration, as gleaned from interlaboratory proficiency testing. Relative standard deviations (RSD) for amphibole asbestos decreased from 50% at 0.8 MFL to 25% at 7 MFL in interlaboratory proficiency testing, while RSD for chrysotile was higher, 50% at 6 MFL.

a. Replicate. A second, independent analysis shall be performed on the same grids but on different grid openings than used in the original analysis of a sample. Results shall be within 1.5X of Poisson standard deviation. This shall be performed at a frequency of 1 per 100 samples. (EPA/600/R-94/134, Method 100.2, Table 2)

b. Duplicate. A second aliquot of sample shall be filtered through a second filter, prepared and analyzed in the same manner as the original preparation of that sample. Results shall be within 2.0X of Poisson standard deviation. This shall be performed at a frequency of one per 100 samples. (EPA/600/R-94/134, Method 100.2, Table 2)

c. Verified analyses. A second, independent analysis shall be performed on the same grids and grid openings used in the original analysis of a sample. The two sets of results shall be compared according to Turner and Steel (NISTIR 5351). This shall be performed at a frequency of one per 20 samples. Qualified analysts shall maintain an average of ≥ 80% true positives, ≤ 20% false negatives, and ≤ 10% false positives.

2. Air.

a. All analyses shall be performed on relocator grids so that other laboratories can easily repeat analyses on the same grid openings.

b. The laboratory and TEM analysts shall obtain mean analytical results on NIST SRM 1876b so that trimmed mean values fall within 80% of the lower limit and 110% of the upper limit of the 95% confidence limits as published on the certificate. These limits are derived from the allowable false positives and false negatives given in subdivision A 2 e (3) of this subsection. SRM 1876b shall be analyzed a minimum of once per year by each TEM analyst.

c. The laboratory shall have documentation demonstrating that TEM analysts correctly classify at least 90% of both bundles and single fibrils of asbestos structures greater than or equal to 1 mm in length in known standard materials traceable to NIST, such as NIST bulk asbestos SRM 1866.

d. Interlaboratory analyses shall be performed to detect laboratory bias. The frequency of interlaboratory verified analysis shall correspond to a minimum of 1 per 200 grid square analyses.

e. If more than one TEM is used for asbestos analysis, intermicroscope analyses shall be performed to detect instrument bias.

(1) Replicate. A second, independent analysis shall be performed in accordance with Section D.6.2.1.1.a. (AHERA, Table III)

(2) Duplicate. A second wedge from a sample filter shall be prepared and analyzed in the same manner as the original preparation of that sample. Results shall be within 2.0X of Poisson standard deviation. This shall be performed at a frequency of 1 per 100 samples. (AHERA, Table III)

(3) Verified analyses. A second, independent analysis shall be performed on the same grids and grid openings in accordance with subdivision A 1 c of this section.

3. Bulk samples. Determination of precision and accuracy should follow guidelines in NISTIR 5951, Guide for Quality Control on the Qualitative and Quantitative Analysis of Bulk Asbestos Samples: Version 1. Because bulk samples with low (< 10%) asbestos content are the most problematic, a laboratory's quality control program should focus on such samples. At least 30% of a laboratory's QC analyses shall be performed on samples containing from 1.0% to 10% asbestos.

a. Intra-analyst precision. At least one out of 50 samples shall be reanalyzed by the same analyst. For single analyst laboratories, at least one out of every 10 samples shall be reanalyzed by the same analyst.

b. Inter-analyst precision. At least one out of 15 samples shall be reanalyzed by another analyst. Inter-analyst results will require additional reanalysis, possibly including another analyst, to resolve discrepancies when classification (ACM vs. non-ACM) errors occur, when asbestos identification errors occur, or when inter-analyst precision is found to be unacceptable.

c. Inter-laboratory precision. The laboratory shall participate in round robin testing with at least one other laboratory. Samples shall be sent to this other lab at least four times per year. These samples shall be samples previously analyzed as QC samples. Results of these analyses shall be assessed in accordance with QC requirements. As a minimum, the QC requirements shall address misclassifications (false positives, false negatives) and misidentification of asbestos types.

B. Phase contrast microscopy.

1. Inter-laboratory precision. Each laboratory analyzing air samples for compliance determination shall implement an inter-laboratory quality assurance program that as a minimum includes participation of at least two other independent laboratories. Each laboratory shall participate in round robin testing at least once every six months with at least all the other laboratories in its inter-laboratory quality assurance group. Each laboratory shall submit slides typical of its own workload for use in this program. The round robin shall be designed and results analyzed using appropriate statistical methodology. Results of this QA program shall be posted in each laboratory to keep the microscopists informed.

2. Intra- and inter-analyst precision. Each analyst shall select and count a prepared slide from a "reference slide library" on each day on which air counts are performed. Reference slides shall be prepared using well-behaved samples taken from the laboratory workload. Fiber densities shall cover the entire range routinely analyzed by the laboratory. These slides shall be counted by all analysts to establish an original standard deviation and corresponding limits of acceptability. Results from the daily reference sample analysis shall be compared to the statistically derived acceptance limits using a control chart or a database. It is recommended that the labels on the reference slides be periodically changed so that the analysts do not become familiar with the samples. Intra- and inter-analyst precision may be estimated from blind recounts on reference samples. Inter-analyst precision shall be posted in each laboratory to keep the microscopists informed.

C. Polarized light microscopy. Refer to subdivision A 3 of this section.

1VAC30-45-823. Asbestos testing: other quality control measures.

A. Transmission electron microscopy.

1. Water and wastewater.

a. Filter preparations shall be made from all six asbestos types from NIST SRMs 1866 and 1867. These preparations shall have concentrations between one and 20 structures (> 10μm) per 0.01 mm². One of these preparations shall be analyzed independently at a frequency of one per 100 samples analyzed. Results shall be evaluated as verified asbestos analysis in accordance with Turner and Steel (NISTIR 5351).

b. NIST SRM 1876b shall be analyzed annually by each analyst. Results shall be evaluated in accordance with limits published for that SRM. This SRM is not strictly appropriate for waterborne asbestos but analysts can demonstrate general TEM asbestos competence by producing results within the published limits of this (the only recognized TEM counting standard) SRM.

2. Air

a. Filter preparations shall be made from all six asbestos types in accordance with subdivision A 1 a of this section.

b. NIST SRM 1876b shall be analyzed annually in accordance with subdivision A 1 b of this section.

3. Bulk samples. All analysts shall be able to correctly identify the six regulated asbestos types (chrysotile, amosite, crocidolite, anthophyllite, actinolite, and tremolite). Standards for the six asbestos types listed are available from NIST (SRMs 1866 and 1867). These materials can also be used as identification standards for AEM (Section 3.2.1 Qualitative Analysis, Page 57, EPA/600/R-93/116).

B. Phase contrast microscopy.

1. Test for nonrandom fiber distribution. Blind recounts by the same analyst shall be performed on 10% of the filters counted. A person other than the counter should re-label slides before the second count. A test for type II error (NIOSH 7400, Issue 2, 15 August 1994, Section 13) shall be performed to determine whether a pair of counts by the same analyst on the same slide should be rejected due to nonrandom fiber distribution. If a pair of counts is rejected by this test, the remaining samples in the set shall be recounted and the new counts shall be tested against first counts. All rejected paired counts shall be discarded. It shall not be necessary to use this statistic on blank recounts.

2. All individuals performing airborne fiber analysis shall have taken the NIOSH Fiber Counting Course for sampling and evaluating airborne asbestos dust or an equivalent course.

3. All laboratories shall participate in a national sample testing scheme such as the Proficiency Analytical Testing (PAT) program or the Asbestos Analysts Registry (AAR) program, both sponsored by the American Industrial Hygiene Association (AIHA), or equivalent.

C. Polarized light microscopy.

1. Friable materials. Because accuracy cannot be determined by reanalysis of routine field samples, at least one out of 100 samples shall be a standard or reference sample that has been routinely resubmitted to determine analyst's precision and accuracy. A set of these samples should be accumulated from proficiency testing samples with predetermined weight compositions or from standards generated with weighed quantities of asbestos and other bulk materials (Perkins and Harvey, 1993; Parekh et al., 1992; Webber et al., 1982). At least half of the reference samples submitted for this QC shall contain between 1.0% and 10% asbestos.

2. Nonfriable materials. At least one out of 100 samples shall be a verified quantitative standard that has routinely been resubmitted to determine analyst precision and accuracy.

1VAC30-45-825. Asbestos testing: asbestos calibration.

Refer to methods referenced in the following sections for specific equipment requirements.

1. Transmission electron microscopy: general. Analytical electron microscopy equipment will not be discussed in this document.

2. Transmission electron microscopy: water and wastewater. All calibrations listed below (unless otherwise noted) shall be performed under the same analytical conditions used for routine asbestos analysis and shall be recorded in a notebook and include date and analyst's signature. Frequencies stated below may be reduced to "before next use" if no samples are analyzed after the last calibration period has expired. Likewise, frequencies may have to be increased following non-routine maintenance or unacceptable calibration performance.

a. Magnification calibration. Magnification calibration shall be done at the fluorescent screen, with the calibration specimen at the eucentric position, at the magnification used for fiber counting, generally 10,000 and 20,000x. A logbook shall be maintained with the dates of the calibration recorded. Calibrations shall be performed monthly to establish the stability of magnification. Calibration data shall be displayed on control charts that show trends over time. (EPA/600/R-94/134, Method 100.2, Section 10.1)

b. Camera constant. The camera length of the TEM in the Selected Area Electron Diffraction (SAED) mode shall be calibrated before SAED patterns of unknown samples are observed. The diffraction specimen shall be at the eucentric position for this calibration. This calibration shall allow accurate (< 10% variation) measurement of layer-line spacings on the medium used for routine measurement, i.e., the phosphor screen or camera film. This shall also allow accurate (< 5.0% variation) measurement of zone axis SAED patterns on permanent media, e.g., film. Calibrations shall be performed monthly to establish the stability of the camera constant (EPA/600/R-94/134, Method 100.2, Section 10.2). Where nonasbestiform minerals may be expected (e.g., winchite, richterite, industrial talc, vermiculite, etc.), an internal camera constant standard such as gold, shall be deposited and measured on each sample to facilitate accurate indexing of zone axis SAED patterns. In such cases, layer line analysis alone shall not be used. Calibration data shall be displayed on control charts that show trends over time.

c. Spot size. The diameter of the smallest beam spot at crossover shall be less than 250 nm as calibrated quarterly. Calibration data shall be displayed on control charts that show trends over time. (EPA/600/R-94/134, Method 100.2, Section 10.3)

d. Beam dose. The beam dose shall be calibrated so that beam damage to chrysotile is minimized, specifically so that an electron diffraction pattern from a single fibril ≥1 μm in length from a NIST SRM chrysotile sample is stable in the electron beam dose for at least 15 seconds.

e. EDXA system.

(1) The x-ray energy vs. channel number for the EDXA system shall be calibrated to within 20 eV for at least two peaks between 0.7 keV and 10 keV. One peak shall be from the low end (0.7 keV to 2 keV) and the other peak from the high end (7 keV to 10 keV) of this range. The calibration of the x-ray energy shall be checked prior to each analysis of samples and recalibrated if out of the specified range.

(2) The ability of the system to resolve the Na Ka line from the Cu L line shall be confirmed quarterly by obtaining a spectrum from the NIST SRM 1866 crocidolite sample on a copper grid.

(3) The k-factors for elements found in asbestos (Na, Mg, Al, Si, Ca, and Fe) relative to Si shall be calibrated semiannually, or anytime the detector geometry may be altered. NIST SRM 2063a shall be used for Mg, Si, Ca, Fe, while k-factors for Na and Al may be obtained from suitable materials such as albite, kaersutite, or NIST SRM 99a. The k-factors shall be determined to a precision (2s) within 10% relative to the mean value obtained for Mg, Al, Si, Ca, and Fe, and within 20% relative to the mean value obtained for Na. The k-factor relative to Si for Na shall be between 1.0 and 4.0, for Mg and Fe shall be between 1.0 and 2.0, and for Al and Ca shall be between 1.0 and 1.75. The k-factor for Mg relative to Fe shall be 1.5 or less. Calibration data shall be displayed on control charts that show trends over time.

(4) The detector resolution shall be checked quarterly to ensure a full-width half-maximum resolution of <175 eV at Mn Ka (5.90 keV). Calibration data shall be displayed on control charts that show trends over time.

(5) The portions of a grid in a specimen holder for which abnormal x-ray spectra are generated under routine asbestos analysis conditions shall be determined and these areas shall be avoided in asbestos analysis.

(6) The sensitivity of the detector for collecting x-rays from small volumes shall be documented quarterly by collecting resolvable Mg and Si peaks from a unit fibril of NIST SRM 1866 chrysotile.

f. Low temperature asher. The low temperature asher shall be calibrated quarterly by determining a calibration curve for the weight vs. ashing time of collapsed mixed-cellulose-ester (MCE) filters. Calibration data shall be displayed on control charts that show trends over time.

g. Grid openings. The magnification of the grid opening measurement system shall be calibrated using an appropriate standard at a frequency of 20 openings/20 grids/lot of 1000 or one opening/sample. The variation in the calibration measurements (2s) is <5.0% of the mean calibration value.

3. Air. All calibrations shall be performed in accordance with subdivision 2 of this section, with the exception of magnification. Magnification calibration shall be done at the fluorescent screen, with the calibration specimen at the eucentric position, at the magnification used for fiber counting, generally 15,000 to 20,000x (AHERA, III.G.1.c). A logbook shall be maintained with the dates of the calibration recorded. Calibrations shall be performed monthly to establish the stability of magnification.

4. Bulk samples. All calibrations shall be performed in accordance with subdivision 3 of this section.

5. Phase contrast microscopy.

a. At least once daily, the analyst shall use the telescope ocular (or Bertrand lens, for some microscopes) supplied by the manufacturer to ensure that the phase rings (annular diaphragm and phase-shifting elements) are concentric.

b. The phase-shift limit of detection of the microscope shall be checked monthly or after modification or relocation using an HSE/NPL phase-contrast test slide for each analyst/microscope combination (refer to NIOSH 7400, Issue 2, 15 August 1994, Section 10b). This procedure assures that the minimum detectable fiber diameter (< ca. 0.25mm) for this microscope is achieved.

c. Prior to ordering the Walton-Beckett graticule, calibration, in accordance with NIOSH 7400, Issue 2, 15 August 1994, Appendix A, shall be performed to obtain a counting area 100 mm in diameter at the image plane. The diameter, d_c (mm), of the circular counting area and the disc diameter shall be specified when ordering the graticule. The field diameter (D) shall be verified (or checked), to a tolerance of 100 μm ± 2 μm, with a stage micrometer upon receipt of the graticule from the manufacturer. When changes (zoom adjustment, disassembly, replacement, etc.) occur in the eyepiece-objective-reticle combination, field diameter shall be remeasured (or recalibrated) to determine field area (mm²). Recalibration of field diameter shall also be required when there is a change in interpupillary distance (i.e., change in analyst). Acceptable range for field area shall be 0.00754 mm² to 0.00817 mm². The actual field area shall be documented and used.

6. Polarized light microscopy.

a. Microscope alignment. To accurately measure the required optical properties, a properly aligned polarized light microscope (PLM) shall be utilized. The PLM shall be aligned before each use. (Section 2.2.5.2.3, EPA/600/R-93/116, July 1993)

b. Refractive index liquids. Series of n_D = 1.49 through 1.72 in intervals less than or equal to 0.005. Refractive index liquids for dispersion staining, high-dispersion series 1.550, 1.605, 1.680. The accurate measurement of the refractive index (RI) of a substance requires the use of calibrated refractive index liquids. These liquids shall be calibrated at first use and semiannually, or next use, whichever is less frequent, to an accuracy of 0.004, with a temperature accuracy of 2°C using a refractometer or RI glass beads.

1VAC30-45-826. Asbestos testing: analytical sensitivity.

A. Transmission electron microscopy.

1. Water and wastewater. An analytical sensitivity of 200,000 fibers per liter (0.2 MFL) is required for each sample analyzed (EPA/600/R-94/134, Method 100.2, Section 1.6). Analytical sensitivity is defined as the waterborne concentration represented by the finding of one asbestos structure in the total area of filter examined. This value will depend on the fraction of the filter sampled and the dilution factor (if applicable).

2. Air. An analytical sensitivity of 0.005 structures/cm² is required for each sample analyzed. Analytical sensitivity is defined as the airborne concentration represented by the finding of one asbestos structure in the total area of filter examined. This value will depend on the effective surface area of the filter, the filter area analyzed, and the volume of air sampled (AHERA, Table I).

3. Bulk samples.

a. The range is dependent on the type of bulk material being analyzed. The sensitivity may be as low as 0.0001% depending on the extent to which interfering materials can be removed during the preparation of AEM specimens. (Section 2.5.2 Range, Page 51, EPA/600/R-93/116)

b. There should be an error rate of less than 1.0% on the qualitative analysis for samples that contain chrysotile, amosite, and crocidolite. A slightly higher error rate may occur for samples that contain anthophyllite, actinolite, and tremolite, as it can be difficult to distinguish among the three types. (Section 3, Page 10, NIST Handbook 150-3, August 1994)

B. Phase contrast microscopy. The normal quantitative working range of the test method is 0.04 to 0.5 fiber/cm² for a 1000 L air sample. An ideal counting range on the filter shall be 100 to 1300 fibers/mm². The limit of detection (LOD) is estimated to be 5.5 fibers per 100 fields or 7 fibers/mm². The LOD in fiber/cc will depend on sample volume and quantity of interfering dust but shall be <0.01 fiber/cm² for atmospheres free of interferences. (NIOSH 7400, Issue 2, 15 August 1994)

C. Polarized light microscopy. The laboratory shall utilize a test method that provides a limit of detection that is appropriate and relevant for the intended use of the data. Limit of detection shall be determined by the protocol in the test method or applicable regulation.

1VAC30-45-827. Asbestos testing: data reduction.

A. Transmission electron microscopy.

1. Water and wastewater.

a. The concentration of asbestos in a given sample shall be calculated in accordance with EPA/600/R-94/134, Method 100.2, Section 12.1. Refer to 1VAC30-45-730 K for additional data reduction requirements.

b. Measurement uncertainties. The laboratory shall calculate and report the upper and lower 95% confidence limits on the mean concentration of asbestos fibers found in the sample (EPA/600/R-94/134, Method 100.2, Section 12.2.2).

2. Air.

a. The concentration of asbestos in a given sample shall be calculated in accordance with the method utilized, e.g., AHERA. Refer to 1VAC30-45-730 K for additional data reduction requirements.

b. Measurement uncertainties. The laboratory shall calculate and report the upper and lower 95% confidence limits on the mean concentration of asbestos fibers found in the sample.

3. Bulk samples.

a. The concentration of asbestos in a given sample shall be calculated in accordance with the method utilized (e.g., EPA/600/R-93/116, July 1993). Refer to 1VAC30-45-730 K for additional data reduction requirements.

b. Measurement uncertainties. Proficiency testing for floor tiles analyzed by TEM following careful gravimetric reduction (New York ELAP Certification Manual Item 198.4) has revealed an interlaboratory standard deviation of approximately 20% for residues containing 70% or more asbestos. Standard deviations range from 20% to 60% for residues with lower asbestos content.

B. Phase contrast microscopy.

1. Airborne fiber concentration in a given sample shall be calculated in accordance with NIOSH 7400, Issue 2, 15 August 1994, Sections 20 and 21. Refer to 1VAC30-45-730 K for additional data reduction requirements.

2. Measurement uncertainties. The laboratory shall calculate and report the intra-laboratory and inter-laboratory relative standard deviation with each set of results. (NIOSH 7400, Issue 2, 15 August 1994)

3. Fiber counts above 1300 fibers/mm² and fiber counts from samples with >50% of the filter area covered with particulate should be reported as "uncountable" or "probably biased." Other fiber counts outside the 100-1300 fibers/mm² range should be reported as having "greater than optimal variability" and as being "probably biased."

C. Polarized light microscopy.

1. The concentration of asbestos in a given sample shall be calculated in accordance with the method utilized (e.g., EPA/600/R-93/116, July 1993). Refer to 1VAC30-45-730 K for additional data reduction requirements.

2. Method uncertainties. The individual laboratory shall determine precision and accuracy for the percent range involved. If point counting and/or visual estimates are used, a table of reasonable expanded errors (refer to EPA/600/R-93/116, July 1993, Table 2-1) should be generated for different concentrations of asbestos.

1. The quality control program shall establish and maintain provisions for asbestos standards.

a. Reference standards that are used in an asbestos laboratory shall be obtained from the National Institute of Standards and Technology (NIST), EPA, or suppliers who participate in supplying NIST standards or NIST traceable asbestos. Any reference standards purchased outside the United States shall be traceable back to each country's national standards laboratory. Commercial suppliers of reference standards shall conform to ANSI N42.22 to assure the quality of their products.

b. Reference standards shall be accompanied with a certificate of calibration whose content is as described in ANSI N42.22-1995, Section 8, Certificates.

2. All reagents used shall be analytical reagent grade or better.

3. The laboratory shall have mineral fibers or data from mineral fibers that will allow differentiating asbestos from at least the following "look-alikes": fibrous talc, sepiolite, wollastonite, attapulgite (palygorskite), halloysite, vermiculite scrolls, antigorite, lizardite, pyroxenes, hornblende, richterite, winchite, or any other asbestiform minerals that are suspected as being present in the sample.

B. Phase contrast microscopy. Standards of known concentration have not been developed for this testing method. Routine workload samples that have been statistically validated and national proficiency testing samples such as PAT and AAR samples available from the AIHA may be utilized as reference samples (refer to 1VAC30-45-822 B 2) to standardize the optical system and analyst. All other testing reagents and devices (HSE/NPL test slide and Walton-Beckett Graticule) shall conform to the specifications of the method (refer to NIOSH 7400, Issue 2, 15 August 1994).

C. Polarized light microscopy. Refer to 1VAC30-45-828 A.

While the laboratory may not have control of field sampling activities, the following are essential to ensure the validity of the laboratory's data.

1. Sample tracking. The laboratory shall have a documented system for uniquely identifying the items to be tested to ensure that there can be no confusion regarding the identity of such items at any time. This system shall include identification for all samples, subsamples and subsequent extracts or digestates or both. The use of container shape, size or other physical characteristic, such as amber glass or purple top, is not an acceptable means of identifying the sample.

If, under 1VAC30-46-90 C, DGS-DCLS determines that the change of ownership or location of laboratory requires reaccreditation of or reapplication by the laboratory, the laboratory shall pay the application fee required under this section.

3. Under 1VAC30-46-60 B 3, the owner of multiple non-contiguous laboratories may request that DGS-DCLS consider these laboratories to be one site. If, as a result of the request being granted, DGS-DCLS needs to perform multiple on-site assessments, DGS-DCLS shall charge a fee for the additional on-site assessments. The fee shall be the sum of reasonable travel costs and labor charges for the additional on-site assessments. The labor charges will be determined following the method in subsection G of this section.

4. Under 1VAC30-46-160, any person regulated by this chapter may petition the director to grant a variance from any requirement of this chapter. DGS-DCLS shall charge a fee for the time needed to review the petition, including any on-site assessment required. The fee shall be determined by the method specified in subsection G of this section.

3. G. Fee determination.

a. 1. The fee shall be the sum of the total hourly charges for all reviewers plus any on-site review costs incurred.

b. 2. An hourly charge per reviewer shall be determined by (i) obtaining a yearly cost by multiplying the reviewer's annual salary by 1.35 (accounts for overhead such as taxes and insurance) and then (ii) dividing the yearly cost by 1,642 (number of annual hours established by DGS fiscal services Fiscal Services, DGS, for billing purposes).

c. 3. The charge per reviewer shall be determined by multiplying the number of hours expended in the review by the reviewer's hourly charge.

d. 4. If an on-site review is required, travel time and on-site review time shall be charged at the same hourly charge per reviewer, and any travel expenses shall be added.

G. On-site assessment fees. When, with the concurrence of the applicant laboratory, DGS-DCLS uses approved, third-party on-site assessors, the cost of the on-site assessment shall be paid by the applicant. H. Out-of-state laboratories – travel costs. The owner of an environmental laboratory located in another state who applies for accreditation under this chapter shall also pay a fee equal to the reasonable travel costs associated with conducting an on-site assessment at the laboratory. Reasonable travel costs include transportation, lodging, per diem, and telephone and duplication charges.

I. DGS-DCLS shall derive the travel costs charged under subsections G and H of this section from the Commonwealth of Virginia reimbursement allowances and rates for lodging, per diem, and mileage.
