Florida Administrative Code › 62 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 62 - Departmental › Chapter 62-709 - CRITERIA FOR ORGANICS PROCESSING AND RECYCLING FACILITIES › Section 62-709.530 - Testing, Recording and Reporting Requirements

Current through Reg. 50, No. 138; July 16, 2024
(1) The compost product shall be sampled and
				analyzed as follows.
(a) A composite sample
				of the compost produced at each composting facility shall be analyzed at
				intervals of every 20, 000 tons of compost produced or every three months,
				whichever comes first, for percent moisture, percent reduction in organic
				matter, percent organic matter, and pH.
(b) In addition to paragraph (a), above, when
				demonstration that a material has been disinfected is required in accordance
				with paragraph  62-709.300(8)(a),
				F.A.C., the material shall be analyzed for one of the following at intervals of
				every 20, 000 tons of material produced or every three months, whichever comes
				first:
1. Fecal Coliform, most probable
				number per gram of total solids (dry weight basis), or
2.
Salmonella
sp. Bacteria,
				most probable number per four grams of total solids (dry weight
				basis).
(c) In addition
				to paragraph (b), above, when the provisions of subparagraph
				 62-709.300(8)(a) 
				2., F.A.C., will be used, the material shall be analyzed for the following at
				intervals of every 20, 000 tons of material produced or every three months,
				whichever comes first:
1. Enteric viruses,
				plaque-forming unit per four grams of total solids (dry weight basis);
				and,
2. Helminth ova, ova per four
				grams of total solids (dry weight basis).
(d) Compost produced by persons for their own
				use, where the compost is made from yard trash, vegetative wastes or manure, is
				not required to be sampled and analyzed as specified in paragraphs (a) through
				(c), above.
(e) In addition to
				paragraphs (a) through (c), above, compost made from solid waste other than
				only yard trash, vegetative wastes, animal byproducts or manure shall be
				analyzed at intervals of every 20, 000 tons of compost produced or every three
				months, whichever comes first, for:
1. Percent
				foreign matter; and,
2. Total
				cadmium, copper, lead, nickel, and zinc, all in mg/kg dry
				weight.
(f) The
				Department may decrease or increase the parameters to be analyzed for or the
				frequency of analysis based on monitoring data, changes in the waste stream or
				processing, or the potential presence of toxic substances.
(g) All sampling and analysis activities
				shall be performed in accordance with Chapter 62-160, F.A.C. Analytical results
				shall be submitted to the appropriate District office within 30 days of sample
				collection.
(h) Foreign matter
				content shall be determined by passing a dried, weighed sample of the compost
				product through a one-quarter inch or six millimeter screen. The material
				remaining on the screen shall be visually inspected, and the foreign matter
				that can be clearly identified shall be separated and weighed. The weight of
				the separated foreign matter divided by the weight of the total sample
				multiplied by 100 shall be the % dry weight of the foreign matter
				content.
(i) The reduction of
				organic matter is determined by comparing the organic matter content of the
				feedstock into the composting process and the organic matter content of the
				compost product. The amount of reduction is determined as a percent of the
				original amount contained in the feedstock using the following calculation:
% ROM = [1 - (OMK(100 - OM)/OM(100 - OMK))]100 where: % ROM =
				  reduction of organic matter, OM = % organic matter
content of dry matter before decomposition, and OMK = %
				  organic matter content of dry matter after
				  decomposition.
