Rule 3745-4-05 | Level 2 data requirements and reporting.
(A) Except as provided by paragraph (D) of rule 3745-4-01 of the Administrative Code, all data submitted to the director for consideration as level 2 credible data shall be collected and submitted by level 2 or level 3 qualified data collectors (QDCs) approved by the director pursuant to rule 3745-4-03 of the Administrative Code. Other persons trained and supervised by the QDC may assist with the collection of data. The director shall accept the data as level 2 credible data provided the requirements of this rule are met. The director shall have sole authority in determining whether data meet these requirements. Data reporting shall be in a format consistent with the requirements listed in this rule.
(B) Data submitted by a QDC shall meet the following to be accepted as level 2 credible data:
(1) Adherence to a study plan. Persons submitting data to Ohio EPA as a QDC under section 6111.53 of the Revised Code shall prepare and adhere to a project study plan.
(a) The QDC shall prepare and submit to the director for approval a project study plan using the guidelines presented in appendix A to this rule. The director may approve an alternative to the guidelines in appendix A of this rule upon a reasonable and scientifically supported demonstration by a QDC.
(b) Upon completion of the plan review, the director shall send written notification of deficiencies in the plan, if any are found, to the QDC and provide the QDC a reasonable opportunity to address such deficiencies. If the deficiencies are not addressed, the director may disapprove the study plan.
(c) A plan submitted by a QDC (level 2 or 3) not disapproved within sixty days of the initial submittal or, where a notification of deficiency has been issued, within sixty days of any revised submittal, shall be considered to have been approved.
(d) The director shall disapprove a site-specific plan that does not include the certification statement in paragraph (B)(4)(e) of this rule.
(2) Use of appropriate test methods. In preparing the project study plan, the QDC shall be responsible for selecting the appropriate field and laboratory methods, including quality assurance and quality control steps, that fit the objectives and purpose of the project. All methods should be commensurate with the purposes of level 2 and the need for sufficient rigor and sensitivity to detect relatively small differences in water quality over time or from sampling site to sampling site. The QDC may select from parameters and test methods published by the director pursuant to paragraph (C) of this rule or similar methods published in the scientific literature. Explicit approval of the specific methods employed shall occur when Ohio EPA reviews project study plans.
(3) All laboratories that perform analysis under a level 2 study plan shall implement a quality assurance program and shall document all elements of the program in a quality assurance manual (QAM) or quality assurance plan (QAP). Guidelines for the elements that should be addressed in the QAM or QAP are presented in appendix B to this rule.
(4) Data reporting. QDCs choosing to submit data to Ohio EPA shall submit all collected data. Submission of data may be done at any time, but shall be done no later than one year after completion of the study identified in the project study plan. For ongoing sampling programs, data submission should begin no later than one year after the initial phase of study identified in the project study plan. The timeframe for submission of data may be extended at the director's discretion for good cause. The following shall be submitted:
(a) Level 2 sample data using the online credible data database, or in a pre-approved format acceptable to the director.
(b) Documentation demonstrating adherence to an approved project study plan.
(c) The results from all quality assurance and quality control samples collected during implementation of the approved project study plan using the online credible data database.
(d) A certification that, to the best of the QDC's knowledge and belief, the data were collected in accordance with the procedures required by the approved project study plan.
(e) A signed statement from each QDC working on the project certifying that the QDC has not been convicted of or pleaded guilty to a violation of section 2911.21 of the Revised Code (criminal trespass) or a substantially similar municipal ordinance within the previous five years.
(5) Reporting laboratory quality assurance and quality control plans. In addition to the information required by paragraph (B)(4) of this rule, the QDC, upon request of the director, shall provide quality assurance and quality control documentation for all laboratories that were used to analyze any data collected pursuant to the approved project study plan. The QDC is responsible for providing this documentation in the form of a laboratory QAP that meets the content guidelines presented in appendix B to this rule.
(6) Data approval process. The director shall review data submissions to verify that they were submitted by a QDC, that appropriate test methods and quality control quality assurance practices were used, and that the data reporting requirements are complete. The review will ensure that all components of the plan for the collection of data were followed. If substantial discrepancies are found, the director may decide not to approve the data. The director shall provide written notification to the person submitting the data as to whether the data have been approved and at what level the data qualify as credible data.
(C) Publication of acceptable methods.
The director from time to time shall publish examples of acceptable level 2 analytical methods for commonly sampled parameters. These can be found online at: https://www.epa.state.oh.us/dsw/credibledata/parameters_testing_methods.
