Any laboratory that is certified, accredited or approved by an organization with which the department has an agreement may apply to the department to be recognized under this paragraph.
(d) Discretionary acceptance. The department may accept the results of a test in a specified test category even though the test was not conducted by a certified or registered laboratory. The department may charge an extra fee if it is necessary to verify the results of a test submitted under this paragraph.
(6) Not applicable to other programs. No laboratory is required to be registered or certified under this section for any purpose other than the submission of results under a covered program.
(7) Certification procedures.
(a) Criteria. After considering recommendations by the council, the department shall promulgate by rule uniform minimum criteria, as provided in this subsection, to be used to evaluate laboratories for certification. Criteria shall be consistent with nationally recognized criteria to the maximum extent possible and shall be designed to facilitate reciprocal agreements under sub. (5).
(b) Methodology.
1. ‘Accepted methodology.’ The department shall prescribe by rule the accepted methodology to be followed in conducting tests in each test category. The department may prescribe by rule accepted sampling protocols and documentation procedures for a specified test category to be followed by the person collecting the samples. The department may prescribe this methodology by reference to standards established by technical societies and organizations as authorized under s. 227.21 (2). The department shall attempt to prescribe this methodology so that it is consistent with any methodology requirements under the resource conservation and recovery act, as defined under s. 289.01 (30), the federal water pollution control act, as amended, 33 USC 1251 to 1376, the safe drinking water act, 42 USC 300f to 300j-10, or the toxic substance control act, 15 USC 2601 to 2629.
2. ‘Revised methodology.’ The department may permit the use of a revised methodology consistent with new or revised editions or standards established by technical societies and organizations on a case-by-case basis.
3. ‘Alternative methodology; confidentiality.’
a. The department may permit the use of an alternative methodology on a case-by-case basis if the laboratory seeking to use that methodology submits data establishing the accuracy and precision of the alternative methodology and if the accuracy and precision obtained through the use of the alternative methodology equals or exceeds that obtained through use of the accepted methodology. The department shall establish by rule the data which is required to be submitted and the criteria for evaluating accuracy and precision of alternative methods.
b. A laboratory seeking to use an alternative methodology may request confidential treatment of any data or information submitted to the department under this paragraph. The department shall grant confidential status for any data or information relating to unique methods or processes if the disclosure of those methods or processes would tend to adversely affect the competitive position of the laboratory.
4. ‘Waiver of the procedure.’ The department may waive any procedure prescribed in the accepted methodology on a case-by-case basis if the laboratory seeking this waiver establishes sufficient reasons for the waiver and that the waiver does not adversely affect the purpose for which the test is conducted.
(c) Reference sample testing. The department may prescribe by rule criteria for determining the accuracy of tests by certified laboratories on reference samples. The department shall provide, to the extent reasonably possible, reference samples prepared by an independent source for a representative cross section of test categories which are to be regularly and routinely performed by certified laboratories. The department may require a certified laboratory to analyze not more than 3 reference samples per year for each test category.
(d) Quality control. The department shall establish by rule minimum requirements for a quality control program which ensures that a laboratory complies with criteria for the accuracy and precision of tests in each test category and which specifies procedures to be followed if these criteria are not met. The department may accept a quality control program based upon state or federal requirements for similar test categories.
(e) Records. Where a particular time period is not otherwise specified by law, the department may prescribe by rule for each test category the length of time laboratory analysis records and quality control data specified in the laboratory’s quality control program are to be retained by the laboratory.
(f) Application for certification. The department shall specify by rule the criteria and standards to be met by applicants for certification. A laboratory desiring to be certified for a specified test category shall make application on forms provided by the department.
(g) Initial certification. The department shall issue an initial certification to a laboratory for a specified test category if all of the following conditions are met:
1. ‘Application.’ The laboratory submits an application requesting certification in a specified test category.
2. ‘Methodology.’ The laboratory specifies a methodology prescribed or permitted under par. (b) which it intends to utilize in conducting tests in the specified test category.
3. ‘Accuracy.’ If the department provides a reference sample, the laboratory conducts a test on the sample and obtains results which comply with the minimum criteria for accuracy for that specified test category.
4. ‘Quality control.’ The laboratory has or agrees to implement a quality control program which meets minimum requirements under par. (d) for the specified test category and which is to commence no later than the date of certification.
(h) Certification period. Certification of laboratories shall be renewed annually. A certification is valid from the date of issuance until it expires, is revoked or suspended.
(i) Suspension and revocation. After considering recommendations from the council, the department shall establish by rule criteria and procedures for the review and evaluation of the certification of laboratories and the suspension or revocation of certifications. If, after opportunity for a contested case hearing, the department finds that a certified laboratory materially and consistently failed to comply with the criteria and procedures established by rule, it may suspend or revoke the certification of the laboratory. A person whose certification is suspended or revoked may reapply for certification upon a showing that the person meets the applicable criteria for certification and has corrected the deficiencies that led to the suspension or revocation.
(8) Registration procedure.
(a) Criteria. Upon application, the department shall register a laboratory if the laboratory complies with the requirements of this subsection, if the laboratory does not perform tests commercially for hire and if:
1. The laboratory performs tests solely on its own behalf or on behalf of a subsidiary or other corporation under common ownership or control; or
2. The laboratory is owned or controlled by a municipality or 2 or more municipalities and performs tests solely on behalf of the municipality or municipalities.
(b) Methodology. Testing by a registered laboratory conducted in connection with a covered program shall be carried out in accordance with sub. (7) (b).
(c) Reference sample testing. The department may require by rule reference sample tests upon application and annually thereafter. If results from these tests do not meet minimum criteria established by rule, the department may require additional reference sample testing. If the laboratory participates in a joint or split sampling program with the federal environmental protection agency, or otherwise obtains independent reference samples, the department may accept those results instead of its own reference samples.
(d) Quality control. The laboratory shall conduct self-audits and a quality control program consistent with criteria specified by rule by the department and based on methods and standards prescribed by rule and considering criteria used by the federal environmental protection agency, ASTM International, the national council on air and stream improvement, the national academy of sciences or other equivalent agency recognized by the department.
(e) Records. Where a particular time period is not otherwise specified by law, the department may prescribe by rule for each test category the length of time laboratory analysis records and quality control data specified in the laboratory’s quality control program are to be retained by the laboratory.
(f) Registration. Registration of laboratories shall be renewed annually. A registration is valid from the date of issuance until it expires, is revoked or suspended.
(g) Suspension or revocation of registration. If, after opportunity for a contested case hearing, the department finds that a registered laboratory has falsified results or has materially and consistently failed to comply with the self-audit procedures and quality control programs provided in par. (d), it may suspend or revoke the registration of the laboratory. A person whose registration is suspended or revoked may reapply for registration upon a showing that the person meets the applicable criteria for registration and has corrected the deficiencies that led to the suspension or revocation.
(h) Certification option. A laboratory which is otherwise eligible to seek registration may elect to apply for certification under sub. (7).
(9) Fees. The department shall promulgate by rule a method for producing an annual schedule of fees for certified and registered laboratories that is designed to recover the costs of administering this section.
