Sampling rationale. Loads may be selected for sampling when observation of the load by AUTHORITY or Facility Operator indicates that it may exceed the allowed Contamination Level. A statistical sampling process will be used to determine the Measured Contamination Level in individual loads.
Sampling rationale. Load samples shall be collected from each of the five (5) specified material streams. The sampling plan considers the participating AUTHORITY Member Agencies as a single source of materials generation. Material streams originating from the Service Area will be considered as separate sampling populations. A total of forty-eight (48) samples shall be collected from each sampling population to achieve the desired level of statistical accuracy. In certain cases, an individual Agency may be selected for focused sampling when there is reason to believe that material coming from that Agency exceeds the established maximum Contamination Level.
Sampling rationale. Loads may be selected for sampling when observation of the load by SBWMA or Contractor indicates that it may exceed the allowed Contamination level. A sampling process will be used to determine the measured Contamination level in individual loads. Sampling allocation Approximately five (5) samples, each weighing approximately one hundred and fifty (150) pounds, are required from an individual load in order to calculate the measured Contamination level with a sufficient level of accuracy. It is expected that a two (2) person crew can obtain, sort, and weigh five (5) samples in a five (5) to seven (7) hours period. Test procedures Test procedures are broken down in to the following steps, which shall be used by SBWMA, or a third party designated by the SBWMA. • Safety training and staff coordination • Sampling and sorting area designation • Sample selection • Sample sorting • Sample disposal • Data management These steps are described in more detail following the definitions of roles. Each step is the responsibility of a specific person or group of people as follows: • sampling crew manager—responsible for selecting samples, working with Operator and the sampling crew, quality control, and compliance with Facility regulations. • sampling crew—responsible for sorting samples. • facility manager—responsible for coordinating with the sampling crew manager. • tipping floor staff—responsible for identifying loads potentially Contaminated beyond the acceptable threshold, creating a designated sampling and sorting area, and ensuring segregation of selected loads in that area. • loader operator(s)—responsible for segregating the selected the load from other loads in the designated sampling and sorting area. Safety training and staff coordination When the sampling crew manager and the sampling crew arrive at the Composting Facility they will participate in any required safety training and put on all required personal protective equipment (see the equipment list shown in Appendix 3). The sampling crew manager will also walk through the process of extracting samples from the designated load with both the loader operator(s) and the tipping floor staff. Sampling and sorting area designation With the input of the tipping floor staff and the loader operator(s), the sampling crew manager and sampling crew will set up in the designated sampling and sorting area near the tipping floor. The sorting area should be in a location near the load to be sampled and from which the loa...
Sampling rationale. Loads may be selected for sampling when observation of the load by SBWMA or Contractor indicates that it may exceed the allowed Contamination Level. A statistical sampling process will be used to determine the Measured Contamination Level in individual loads. Sampling allocation Approximately five (5) samples, each weighing approximately one hundred and fifty (150) pounds, are required from an individual load in order to calculate the Measured Contamination Level with a sufficient level of accuracy for Plant Material, Segregated Wood Waste, Brush, Logs and Branches. Because of the variability typically found in loads of Commercial Organic Materials and Food Waste, approximately fifteen (15) samples of two hundred (200) pounds are required for sampling to achieve the specified level of accuracy. The recommended numbers of samples are based on the following factors:
