Current through Register Vol. 28, No. 4, October 1, 2024
Section 7103-153.0 - Sample Collection and Analysis153.1 Sample Collection. All sludge generators and preparers shall develop a sludge sampling program which addresses random and cyclic variations within the sludge stream. The generator or preparer must receive Department approval prior to execution of this program. The EPA publication POTW Sludge Sampling and Analysis Guidance Document may be helpful in establishing a sampling and analysis program. Specifically, the program shall address, with respect to both stabilized and unstabilized sludges, the following: 153.1.1 Sampling equipment, personnel, and containers, including set-up, tear-down and cleaning procedures153.1.2 Representative sampling (collection points, compositing method, frequency and timing of sampling)153.1.3 Sample preservation153.1.4 Recordkeeping/logbook153.1.5 Transfer and Chain-of-Custody Samples 153.2 Methods in the publications listed below shall be used to analyze samples of sewage sludge. The publications are listed as they existed on the effective date of this Regulation. Notice of and change in the listed methods will be published in the Federal Register. The Department will make a sincere effort to notify permittees of any testing method changes; however, it is the responsibility of all parties governed by these regulations to perform analysis using current EPA approved testing methods. 153.2.1 Enteric viruses.

The laboratory may be required to submit a documented Quality Assurance (QA) program for Department approval; the QA program must identify sampling and test procedures in sufficient detail so as to allow a technical evaluation. All sludge generating facilities shall submit a description of the proposed sludge analysis program, which shall address:153.3.1 Laboratories used, addresses, qualifications153.3.2 Parameters analyzed at each laboratory for each medium (water, soil, sludge)153.3.3 QA/QC procedures utilized, results of procedures153.3.4 Methodologies employed, citation for methodologies The applicant must receive Department approval prior to execution of this program.
153.4 Where the regulations require a soils analysis to be performed in order to determine cumulative metals loading, a complete digestion process is required, and the specific testing method shall be referenced in the report; leachate tests would only be appropriate when testing to determine exchangeable cations uptake of metals by the plant-root system.7 Del.
