Laboratories performing only simple test procedures applying for an exemption under 1VAC30-45-120 shall pay an initial application fee of $300 plus an additional fee based on the actual time needed for DCLS to assess the exemption request. The total fee shall not exceed the actual time DCLS takes to assess the exemption request. The fee assessed shall be calculated using the method in subsection G of this section.

4. Under 1VAC30-45-140, any person regulated by this chapter may petition the director to grant a variance from any requirement of this chapter. DCLS shall charge an initial fee of $700 plus an additional fee based on the actual time needed for DCLS to review the petition, including any on-site assessment required. The total fee shall not exceed the actual time DCLS takes to review and make a determination on the request for a variance. The fee shall be determined by the method specified in subsection G of this section.

G. Fee determination.

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

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 Fiscal Services, the Department of General Services, for billing purposes).

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

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.

H. Out-of-state laboratories - travel costs. The owner of an environmental laboratory located in another state who applies for certification 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. 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.

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

A. Result categories.

1. The criteria described in this section apply individually to each FoPT, 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 one PT study for each requested FoC.

2. Once a laboratory has been granted certification status, it shall continue to complete PT studies for each FoPT and maintain a history of at least one acceptable PT study each calendar year. The laboratory shall complete its PT studies by September 30 of each calendar year.

3. When the PT sample used for initial certification was analyzed by the laboratory prior to the date of application, the analysis date of the PT sample shall be no more than 12 months prior to the application date of certification.

4. For a laboratory performing supplemental testing, the PT studies shall be at least 15 calendar days apart from the closing date of one study to the shipment date of another study for the same FoPT.

5. When the PT study result is reported by the PT provider as "acceptable" the environmental laboratory has satisfied the PT requirement.

6. When the PT study result is "not acceptable," the environmental laboratory shall follow the procedure in subsection C of this section.

7. DCLS shall consider a laboratory's analytical result for a FoPT not acceptable when the laboratory makes any reporting error or omission that results in a nonspecific match between the analytical result for the FoPT and any criterion that identifies the laboratory or the field of certification for which the PT sample was analyzed for the purpose of initial or continued certification.

C. Procedure and requirements for "not acceptable" PT study results.

1. When a laboratory receives a PT study result of "not acceptable," the laboratory shall determine the cause for the failure and perform and document corrective action. The corrective action documentation shall be completed within 30 days of receiving the "not acceptable" PT study result and be submitted to DCLS upon request. DCLS may extend the time for corrective action and documentation.

2. Upon completion of the corrective action the laboratory shall perform another PT study for each FoPT that had a "not acceptable" result.

3. If the laboratory successfully completes the makeup PT study by receiving an "acceptable" result before December 31, DCLS shall not suspend the laboratory's certification for the pertinent FoC.

4. If the laboratory receives a "not acceptable" result on the makeup PT study, DCLS shall notify the laboratory that there is cause to suspend the laboratory's certification for the FoC for which the PT study was "not acceptable."

5. DCLS shall not extend the period for annual PT study completion beyond December 31 each year. Failure to satisfactorily complete a PT study, including any corrective action and makeup PT study, by December 31 shall result in suspension of certification in total or in part.

6. If the laboratory receives a "not acceptable" result on three successive PT studies, DCLS shall decertify the laboratory for the pertinent FoC until such time that the laboratory:

a. Completes corrective action for all failed studies and submits its corrective action report to DCLS;

b. Obtains an "acceptable" result for the PT studies; and

c. Applies for a change to its scope of certification and pays applicable fees required by 1VAC30-45-90 B and 1VAC30-45-130 F.

7. DCLS shall follow the provisions of 1VAC30-45-110 in decertifying the laboratory.

D. Withdrawal from PT studies. A laboratory may withdraw from a PT study for any FoPT on or before the close date of the study. Withdrawing from a study shall not exempt the laboratory from meeting the annual analysis requirements necessary for continued certification.

1VAC30-45-730. Test methods and standard operating procedures.

A. Methods documentation.

1. The laboratory shall have documented instructions on the use and operation of all relevant equipment, on the handling and preparation of samples, and for calibration or testing, where the absence of such instructions could jeopardize the calibrations or tests.

2. All instructions, standards, manuals and reference data relevant to the work of the laboratory shall be maintained up to date and be readily available to the staff.

B. Standard operating procedures (SOPs).

1. Laboratories shall maintain SOPs that accurately reflect all phases of current laboratory activities such as assessing data integrity, corrective actions, handling customer complaints, and all test methods. These documents, for example, may be equipment manuals provided by the manufacturer or internally written documents. The test methods may be copies of published methods as long as any changes or selected options in the methods are documented and included in the laboratory methods manual.

2. The SOPs shall be organized. Each SOP shall clearly indicate the effective date of the document, the revision number, and the signature or signatures of the responsible laboratory manager or managers.

3. Copies of all SOPs shall be accessible to all personnel.

C. SOPs for laboratory methods.

1. The laboratory shall have and maintain an SOP for each certified analyte or test method.

2. This SOP may be a copy of a published or referenced method or may be written by the laboratory. In cases where modifications to the published method have been made by the laboratory or where the referenced test method is ambiguous or provides insufficient detail, these changes or clarifications shall be clearly described. Each test method shall include or reference where applicable:

a. Identification of the test method;

b. Applicable matrix or matrices;

c. Limits of detection or quantitation;

d. Scope and application, including parameters to be analyzed;

e. Summary of the test method;

f. Definitions;

g. Interferences;

h. Safety;

i. Equipment and supplies;

j. Reagents and standards;

k. Sample collection, preservation, shipment and storage;

l. Quality control;

m. Calibration and standardization;

n. Procedure;

o. Data analysis and calculations;

p. Method performance;

q. Pollution prevention;

r. Data assessment and acceptance criteria for quality control measures;

s. Corrective actions for out-of-control data;

t. Contingencies for handling out-of-control or unacceptable data;

u. Waste management;

v. References; and

w. Any tables, diagrams, flowcharts and validation data.

D. Test methods.

1. Laboratories shall use (i) promulgated test methods in accordance with the Code of Federal Regulations; (ii) test methods stated in any current permit issued by the State Air Pollution Control Board, the Virginia Waste Management Board, or the State Water Control Board; or (iii) alternate test procedures approved by the board issuing the permit or the Department of Environmental Quality, including applicable quality assurance requirements, and sample preservation, container, storage, and holding time requirements.

2. The laboratory shall use appropriate test methods and procedures for all tests and related activities within its responsibility (including sample handling, transport and storage, preparation and analysis). The method and procedures shall be consistent with the accuracy required and with any standard specifications relevant to the calibrations or tests concerned.

3. When the use of reference test methods for a sample analysis is mandated, only those methods shall be used.

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 initial 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 quality system matrix in which no target analytes or interferences are present at concentrations that impact the results of a specific test method), for example, drinking water, solids, biological tissue and air. Laboratories shall follow the procedure in subsection F of this section to demonstrate capability.

2. Thereafter, ongoing 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 for at least one year prior to applying for certification, 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 document each demonstration of capability as required by subsection G of this section.

5. The laboratory shall complete a demonstration of capability each time there is a change in instrument type, personnel or test method, including the addition of an analyte to a certified test method.

F. Procedure for demonstration of capability. The following steps shall be performed 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:

1. A quality control (QC) sample may be obtained from an outside source or may be prepared by the laboratory using alternate source stock standards that are prepared independently from those used in instrument calibration.

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 of 1-4 times the limit of quantitation.

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

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 shall assess performance against established and documented criteria.

5. Compare the information from subdivision 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.

6. When one or more of the tested parameters fail at least one of the acceptance criteria, the analyst shall proceed according to either subdivision 6 a or 6 b of this subsection.

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

b. Beginning with subdivision 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 3 of this subsection.

G. Documentation of demonstration of capability. The laboratory shall document each demonstration of capability so that the following information shall be readily available for each employee:

1. Analyst or analysts involved in preparation and analysis.

2. Matrix.

3. Analytes, class of analytes, measured parameters, or organisms.

4. Identification of methods performed.

5. Identification of laboratory-specific SOP used for analysis, including revision number.

6. Date or dates of analysis.

8. Data evaluation required by subsection F of this section.

H. Sample aliquots. Where sampling (as in obtaining sample aliquots from a submitted sample) is carried out as part of the test method, the laboratory shall use documented procedures and appropriate techniques to obtain representative subsamples.

I. Data verification. Calculations and data transfers shall be subject to appropriate checks. The laboratory shall establish standard operating procedures to ensure that (i) the reported data are free from transcription and calculation errors and (ii) all quality control measures are reviewed and evaluated before data are reported. The laboratory also shall establish standard operating procedures addressing manual calculations including manual integrations.

J. Documentation and labeling of standards and reagents. Documented procedures shall exist for the reception and storage of consumable materials used for the technical operations of the laboratory.

1. The laboratory shall retain records for all standards, reagents, reference materials and media including the manufacturer/vendor, the manufacturer's Certificate of Analysis or purity (if available), the date of receipt, recommended storage conditions, and an expiration date after which the material shall not be used unless its reliability is verified by the laboratory.

2. Original containers (such as provided by the manufacturer or vendor) shall be labeled with an expiration date if this date is provided by the manufacturer or vendor.

3. Records shall be maintained on standard and reference material preparation. These records shall indicate traceability to purchased stocks or neat compounds, reference to the method of preparation, date of preparation, expiration date and preparer's initials.

4. Sufficient identification of containers of prepared reagents and standards shall be provided to ensure proper performance of tests.

K. Computers and electronic data related requirements. Where computers, automated equipment or microprocessors are used for the capture, processing, manipulation, recording, reporting, storage or retrieval of test data, the laboratory shall ensure the following:

1. Computer software developed by the user is documented in sufficient detail and is suitably validated as being adequate for use.

2. Procedures are established and implemented for protecting the integrity of data, such as integrity of data entry or capture, data storage, data transmission and data processing.

3. Computer and automated equipment are maintained to ensure proper functioning and provided with the environmental and operating conditions necessary to maintain the integrity of calibration and test data.

4. Appropriate procedures are established and implemented for the maintenance of security of data including the prevention of unauthorized access to, and the unauthorized amendment of, computer records.

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

A. General requirements. All equipment used for environmental tests, including equipment for subsidiary measurements (e.g., for environmental conditions) having a significant effect on the accuracy or validity of the result of the environmental test or sampling shall be calibrated before being put into service and on a continuing basis. The laboratory shall have an established program and procedure for the calibration of its 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.

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.

3. Where traceability of measurements to the International System of Units (SI) is not possible or not relevant, the same requirements for traceability to, for example, certified reference materials, agreed methods or consensus standards, are required. 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 would not be invalidated. Where commercially available, this traceability shall be to a national standard of measurement.

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. On each day the equipment is used, 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 in the 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 and make it available for review.

(2) The laboratory shall retain sufficient raw data records 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 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 in the 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.

(c) The laboratory shall perform a continuing instrument calibration verification as follows:

(i) At the beginning and end of each analytical batch. If an internal standard is used, only one verification 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.

(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.

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

(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 verified calibration, sample analyses shall not occur until the analytical system is calibrated or calibration verified. 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 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. 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 or internal quality control using secondary reference materials or both.

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 (e.g., total phosphate should be greater than or equal to orthophosphate).

B. Essential quality control procedures. The general quality control principles in subsection C 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. 1VAC30-45-770 through 1VAC30-45-775, 1VAC30-45-790 through 1VAC30-45-798, and 1VAC30-45-810 through 1VAC30-45-818 specify quality control requirements for chemical testing, microbiological testing, and air testing, respectively. Noncommercial environmental laboratories that analyze environmental samples using other types of testing such as toxicity, radiochemical, or asbestos testing shall meet the quality control standards for the specific method and the specific type of testing in the 2009 TNI Standards for Environmental Laboratories. The standards for any given test type shall assure that the applicable principles are addressed.

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.

1VAC30-45-760. Quality control requirements.

A. General.

1. The quality control protocols specified by the laboratory's SOPs shall be followed (1VAC30-45-730 C). The laboratory shall ensure that either the (i) applicable essential standards outlined in this section through 1VAC30-45-775, 1VAC30-45-790 through 1VAC30-45-798, and 1VAC30-45-810 through 1VAC30-45-818 or (ii) mandated methods or regulations, whichever are more stringent, are incorporated into their method SOPs. When it is not apparent which is more stringent, the quality controls in the mandated method or regulations are 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 microbiology, the requirements of subdivisions 1 and 2 of this subsection apply. For microbiology testing, the initial test method evaluation requirements are contained in 1VAC30-45-790 through 1VAC30-45-798. 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 or analytes 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 and 1VAC30-45-814. 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; amended, Virginia Register Volume 32, Issue 22, eff. September 1, 2016; Errata, 32:24 VA.R. XXX July 25, 2016.

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 (e.g., 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 components 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:

Number of analytes in LCS

Number of analytes allowed in ME of the LCS control limit

Greater than 90

Five

71‑90

Four

51‑70

Three

31‑50

Two

11‑30

One

Fewer than 11

None

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 components 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 measurement quality objectives. 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.

1VAC30-45-771. Chemical testing: limit of detection and limit of quantitation.

A. General. All procedures used shall be documented. Documentation shall include the quality system matrix type. All supporting data shall be retained.

B. Limit of detection (LOD). The laboratory shall utilize a test method that provides an LOD that is appropriate and relevant for the intended use of the data. An LOD is not required for a test method when test results are not reported outside of the calibration range. LODs shall be determined by the protocol in the mandated test method or applicable regulation. If the protocol for determining LODs is not specified, the selection of the procedure shall reflect instrument limitations and the intended application of the test method.

1. The LOD shall be initially determined for the compounds of interest in each test method in a quality system matrix in which there are no target analytes or interferences at a concentration that would impact the results. Alternatively the LOD shall be determined in the quality system matrix of interest (see definition of matrix).

2. LODs shall be determined each time there is a change in the test method that affects how the test is performed, or when a change in instrumentation occurs that affects the sensitivity of the analysis.

3. The LOD shall be verified annually for each quality system matrix, method and analyte according to the procedure specified in 1VAC30-45-760 B 1.

C. Limit of quantitation (LOQ).

1. Any established LOQ shall be above the LOD.

2. The LOQ shall be verified annually for each quality system matrix, method and analyte according to the procedure specified in 1VAC30-45-760 B 2. Alternatively, the annual LOQ verification is not required if the LOD is reevaluated or verified according to subdivision B 3 of this section.

1VAC30-45-850. Sample handling, sample acceptance policy, and sample receipt.

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. System laboratories shall use a permanent chronological record such as a logbook or electronic database to document receipt of all containers. This sample receipt log shall record the following at a minimum: name of facility where sample was taken, date and time of laboratory receipt, unique laboratory ID code, and signature or initials of the person making the entries.

2. Sample acceptance policy. The laboratory shall have a written sample acceptance policy that clearly outlines the circumstances under which samples shall be accepted or rejected. The policy shall ensure that only properly obtained samples with appropriate sampling records (see 1VAC30-45-640 B) are analyzed and that the samples are handled properly. This sample acceptance policy shall be made available to sample collection personnel. The policy shall include elements such as appropriate documentation of the sample's identification, use of appropriate sample containers, adherence to specified holding times, adequate sample volume to perform necessary tests, and procedures to be used when samples show signs of damage, contamination or inadequate preservation.

3. Sample receipt protocols.

a. Upon receipt, the condition of the sample, including any abnormalities or departures from standard condition as prescribed in the relevant test method, shall be recorded. All items specified by the sample acceptance policy shall be checked.

b. All samples that require thermal preservation shall be considered acceptable if the arrival temperature is either within 2°C of the required temperature or the method specified range. For samples with a specified temperature of 4°C, samples with a temperature of ranging from just above freezing temperature of water to 6°C shall be acceptable. Samples that are hand delivered to the laboratory immediately after collection or on the same day that are collected may not meet these criteria. In these cases, the samples shall be considered acceptable if there is evidence that the chilling process has begun such as arrival on ice. Thermal preservation is not required in the field if the laboratory receives the sample and either begins the analysis or refrigerates the sample within 15 minutes of collection.

c. The laboratory shall implement procedures for checking chemical preservation using readily available techniques, such as pH or free chlorine prior to or during sample preparation or analysis.

d. The results of all checks required by the sample acceptance policy and relevant test method shall be recorded.

4. Storage conditions.

a. The laboratory shall have documented procedures and appropriate facilities to avoid deterioration, contamination or damage to the sample during storage, handling, preparation, and testing. Any relevant instructions provided with the item shall be followed. Where items have to be stored or conditioned under specific environmental conditions, these conditions shall be maintained, monitored and recorded.

b. Samples shall be stored according to the conditions specified by preservation protocols:

(1) Samples that require thermal preservation shall be stored under refrigeration that is within 2°C of the specified preservation temperature unless method specific criteria exist. For samples with a specified storage temperature of 4°C, storage at a temperature above the freezing point of water to 6°C shall be acceptable.

(2) Samples shall be stored away from all standards, reagents, food and other potentially contaminating sources. Samples shall be stored in such a manner to prevent cross contamination.

c. Sample fractions, extracts, leachates and other sample preparation products shall be stored according to subdivision 4 a of this section or according to specifications in the test method.

d. Where a sample or portion of the sample is to be held secure (e.g., for reasons of record, safety or value, or to enable check calibrations or tests to be performed later), the laboratory shall have storage and security arrangements that protect the condition and integrity of the secured items or portions concerned.

5. Sample disposal. The laboratory shall have standard operating procedures for the disposal of samples, digestates, leachates and extracts or other sample preparation products.

1VAC30-45-860. Laboratory report format and contents.

A. The results of each test or series of tests carried out by the laboratory shall be reported accurately, clearly, unambiguously and objectively. The results shall normally be reported in a test report required by regulation and shall include all the information necessary for the interpretation of the test results and all information required by the method used.

B. Where the certificate or report contains results of tests performed by subcontractors, these results shall be clearly identified by subcontractor name or applicable certification number.

C. After issuance of the report, the laboratory report shall remain unchanged. Material amendments to a calibration certificate, test report or test certificate after issue shall be made only in the form of a further document, or data transfer including the statement "Supplement to Test Report or Test Certificate, serial number... (or as otherwise identified)," or equivalent form of wording. Such amendments shall meet all the relevant requirements of this article.
