If an applicable air regulation or permit provides for a choice of test methods, the selected method must be approved by the Department. If an applicable air regulation or permit does not specify use of an EPA standard reference method, the alternative test method to be used must be approved by the Department.

(3)

(a) The owner, operator, or representative of a source proposing to use alternative source test methods shall ensure that the alternative source test method is either validated according to EPA Reference Method 301 ( 40 CFR Part 63, Appendix A, December 29, 1992) and any subsequent amendments or editions, or approved by the Department.

(b) The owner, operator, or representative shall ensure that requests for approval of alternative source test methods are submitted to the Department along with the site-specific test plan, and that the submission contains all of the information required by Section IV(C) below.

(4) The Department shall determine whether any source test method proposed in the site-specific test plan is appropriate for use.

(5)

(a) The owner, operator, or representative shall submit site-specific test plans or a letter which amends a previously approved test plan at least forty-five (45) days prior to the proposed test date or as otherwise specified by a relevant federal or state requirement. Sources conducting tests for substances listed in Regulation 61-62.5, Standard No. 8, shall submit site-specific test plans or a letter which amends a previously approved test plan at least sixty (60) days prior to the proposed test date.

(b) If the only amendments to a previously approved test plan are to facility information included in Section IV(C)(1)(a) and (C)(1)(b) below, the requirement in Section IV(B)(5)(a) above will not apply. The owner, operator, or representative however, shall submit the amendments at least two (2) weeks prior to the proposed test date.

(6) Within thirty (30) days of site-specific test plan receipt, the Department will notify the owner, operator, or representative of site-specific test plan approval or denial or will request additional information.

Submission of a site-specific test plan or amendments to a previously approved test plan does not constitute notification. Requirements for a complete notification include the following:

(a) Facility name, permit number, mailing address, physical address, and contact name and phone number;

(b) Source(s) being tested, source identification number(s), and pollutant(s) being tested;

(c) Proposed test date and start time for each source being tested; and

(d) Approved test plan being used to conduct the test identified by Department approval date.

(2) In the event the owner, operator, or representative is unable to conduct the source test on the date specified in the notification, the owner, operator, or representative shall notify the Department as soon as practical by telephone and follow up in writing within thirty (30) days. Telephone notification shall include a description of the circumstance(s) causing the cancellation of the test, and a projected retest date. The written follow-up report shall include a description of the condition(s) which prevented the source test from being conducted, and when applicable, what corrective action was performed, or what equipment repairs were required.

(3) Rescheduling of canceled source tests must meet the two-week notice requirement. However, shorter notification periods may be allowed subject to Department approval.

(4) All tests shall be conducted by or under the direction of a person qualified by training and/or experience in the field of air pollution testing or, where required by federal regulation, meeting the minimum competency requirements for air emissions testing as specified in ASTM D7036-04, Standard Practice for Competence of Air Emission Testing Bodies.

(5) Unless approved otherwise by the Department, the owner, operator, or representative shall ensure that source tests are conducted while the source is operating at the maximum expected production rate or other production rate or operating parameter which would result in the highest emissions for the pollutants being tested or as otherwise specified in a relevant federal or state requirement. Examples of the operating parameters that may affect emission rates are: type and composition of raw materials and fuels, isolation of control equipment modules, product types and dimensions, thermal oxidizer combustion temperature, atypical control equipment settings, etc. Some sources may have to spike fuels or raw materials to avoid being permitted at a more restrictive feed or process rate. Any source test performed at a production rate less than the rated capacity may result in permit limits on emission rates, including limits on production if necessary.

(6) When conducting a source test subject to this section, the owner, operator, or representative of a source shall provide the following:

(a) Department access to the facility to observe source tests;

(b) Sampling ports adequate for test methods;

(c) Safe sampling site(s);

(d) Safe access to sampling site(s);

(e) Utilities for sampling and testing equipment; and

(f) Equipment and supplies necessary for safe testing of a source.

(E) Source Test Method Performance Audit Program

(1) The Department may request that samples collected during any source tests be split with the Department for analysis by an independent or Department laboratory. Any request for split samples will be made in advance of the source test.

(2) Performance testing shall include a test method performance audit (PA) during the performance test if a PA sample is commercially available.

(a) PAs consist of blind audit samples supplied by an accredited audit sample provider (AASP) and analyzed during the performance test in order to provide a measure of test data bias.

(b) An "accredited audit sample provider (AASP)" is an organization that has been accredited to prepare audit samples by an independent, third party accrediting body.

(3) The source owner, operator, or representative of the tested facility shall obtain an audit sample, if commercially available, from an AASP for each test method used for regulatory compliance purposes.

(a) No audit samples are required for the following test methods: Methods 3A and 3C of Appendix A-2 of 40 CFR Part 60; Methods 6C, 7E, 9, and 10 of Appendix A-4 of 40 CFR Part 60; Method 18 of Appendix A-6 of 40 CFR Part 60; Methods 20, 22, and 25A of Appendix A-7 of 40 CFR Part 60; and Methods 303, 318, 320, and 321 of Appendix A of 40 CFR Part 63.

(b) If multiple sources at a single facility are tested during a compliance test event, only one audit sample is required for each method used during a compliance test.

(c) Upon request, the Department may waive the requirement to include an audit sample if the Department determines that an audit sample is not necessary. A waiver of the performance audit requirements to conduct a PA for a particular source does not constitute a waiver of performance audit requirements for future source tests.

(d) "Commercially available" means that two or more independent AASPs have blind audit samples available for purchase. If the source owner, operator, or representative cannot find an audit sample for a specific method, the owner, operator, or representative shall consult the EPA Web site at the following URL http://www.epa.gov/ttn/emc, to confirm whether there is an AASP that can supply an audit sample for that method.

(e) If the EPA Web site does not list an available audit sample at least 60 days prior to the beginning of the compliance test, the source owner, operator, or representative shall not be required to include an audit sample as part of the quality assurance program for the compliance test.

(f) When ordering an audit sample, the source, operator, or representative shall give the AASP an estimate for the concentration of each pollutant that is emitted by the source or the estimated concentration of each pollutant based on the permitted level and the name, address, and phone number of the Department.

(g) The source owner, operator, or representative shall report the results for the audit sample along with a summary of the emission test results for the audited pollutant to the Department and shall report the results of the audit sample to the AASP. The source owner, operator, or representative shall make both reports at the same time and in the same manner or shall report to the Department first and then report to the AASP.

(h) If the method being audited is a method that allows the samples to be analyzed in the field and the tester plans to analyze the samples in the field, the tester may analyze the audit samples prior to collecting the emission samples provided a representative of the Department is present at the testing site. The source owner, operator, or representative may request in the test protocol a waiver to the requirement that a representative of the Department must be present at the testing site during the field analysis of an audit sample.

(i) The final test report shall document any attempt to obtain an audit sample and, if an audit sample was ordered and utilized, the pass/fail results as applicable.

(4) The Department shall have discretion to require any subsequent remedial actions of the owner, operator, or representative based on the split samples and/or performance audit results.

(F) Final Source Test Report

(1) The owner, operator, or representative of a source subject to this section shall submit a written report of the final source test results to the Department by the close of business on the thirtieth (30th) day following the completion of the test, unless an alternative date has been requested in and approved with the site-specific test plan prior to testing or is otherwise specified in a relevant federal or state requirement.

(2) The final test report for each site-specific test plan shall contain, at a minimum, the following supporting information when applicable:

(a) Summary of the results;

(b) Emission calculations and emission rates in units of the applicable standard, permit limit, etc.;

(c) Allowable emission rates in units of the applicable standard, permit limit, etc.;
