a solid waste activity if the TCLP - Regulatory Limits or allowable limits for additional contaminants as determined in the facility or activity license have been equaled or exceeded. This determination must be made either through TCLP testing or through calculation utilizing the methodology described in Appendix 405.E.
(d)A reduction in characterization requirements may be requested based on the generator's certification of waste history, process knowledge, and waste volume. The Department may also require additional parameters based upon the raw material, the proposed activity, or the facility.
(2)Waste Characterization Sampling and Analytical Work Plan. A waste characterization sampling and analytical work plan must be developed for initial and ongoing characterization of solid wastes, including residuals, handled under a solid waste license. The plan must include, at a minimum, a detailed description of the contaminants of concern in the waste or residual, the sampling and analytical methods used to obtain samples and quantify contaminants, and the guidance or other references used to develop the plan. The plan must be prepared in accordance with the specific analytical requirements of Section 6.C or 6.D.
The sampling plan must include:
(i)identification of parameters to be analyzed and selection rationale;
(ii)sample collection methods including a description of sampling equipment and how representative samples will be obtained;
(iii)sample point description;
(iv)sample size, sample type (e.g., grab, composite), and sample frequency;
(v)procedures for decontamination of sampling equipment prior to sampling and between the collection of successive samples;
(vi)sample container, storage and preservation procedures;
(vii) sample holding times;
(viii) sample handling, packaging, and transportation protocols;
(ix)sample documentation (labeling, chain-of-custody, log book);
(xi)estimated practical quantitative limits for each parameter to be quantified;
(xii) sampling and analysis quality assurance/quality control procedures; and
(xiii) data reduction, validation and reporting methods including methods of statistical interpretation of analytical results.
In order to assure adequate waste characterization, the plan must be developed in accordance with Department-approved State or Federal guidance documents.
