§ 17868.3.1. Physical Contamination Limits.
This section shall become operative January 1, 2018.
(a) Compost shall not contain more than 0.5% by dry weight of physical contaminants greater than 4 millimeters; no more than 20% by dry weight of this 0.5% shall be film plastic greater than 4 millimeters. Compost that contains physical contaminants in excess of either one or both of these limits shall be designated for additional processing, disposal or other use as approved by local, state or federal agencies having appropriate jurisdiction. Verification of physical contamination limits shall occur prior to the point where compost is removed from the site or beneficially used on-site. Test results of samples must be received by the operator prior to removing compost from the composting operation or facility where it was produced.
(b) The operator of a compostable material handling operation or facility shall sample every 5,000 cubic-yards of compost produced and determine the percentage of physical contaminants greater than 4 millimeters in the sample using a method that provides accurate results and has been approved by the EA. If the compostable material handling operation or facility produces less than 5,000 cubic-yards of compost in a 12 month period, the operator shall analyze at least one composite sample of compost produced every 12 month period.
(c) If the EA has reason to believe, based on the EA's visual observation or otherwise, that a determination of percent physical contaminants made pursuant to section 17868.3.1(b) is not accurate, the EA may require an operator of a compostable material handling operation or facility to take a composite sample of compost in the presence of the EA and send the sample to a laboratory at which physical contaminants greater than 4 millimeters shall be collected and weighed to determine the percentage of physical contaminants by dry weight using the following protocol:
(1) Determine the total dry weight of the composite sample as obtained in section 17868.3.1(d);
(2) Separate the physical contaminants greater than 4 millimeters from the composite sample and determine the dry weight of the physical contaminants;
(3) Determine the percentage of physical contaminants by dividing the dry weight of the physical contaminants by the total dry weight of the composite sample.
(d) Any sampling conducted to comply with this section shall require a composite sample. A composite sample shall be representative and random, and may be obtained by taking twelve (12) mixed samples as described below.
(1) The twelve samples shall be of equal volume.
(2) The twelve samples shall be extracted from within the compost pile as follows:
(A) Four samples from one-half the width of the pile, each at a different cross-section;
(B) Four samples from one-fourth the width of the pile, each at a different cross-section; and,
(C) Four samples from one-eighth the width of the pile, each at a different cross-section.
(e) Alternative methods of compliance to meet the requirements of this section may be approved by the EA if the EA determines that the alternative method will ensure the physical contamination limits requirements of this section are met.
