Section 520.15. Determination of waste tonnages.

 

(1)   Determination by owner or operator. The owner or operator shall determine the number of tons of waste received and disposed of at the solid waste land disposal facility in accordance with the following:

(a) For landfills with weight scales, actual weight records shall be used, and all waste accepted shall be routed across the scale.

(b) For landfills without scales, the owner or operator may establish by field measurement the volume of waste disposed and convert to a weight using the appropriate conversion factors in Table 4. When reporting waste tonnage information to the department based on this method, owners or operators of municipal solid waste landfills shall specify the volume of cover soil used as well as how the volumes of municipal waste and various industrial wastes were determined.

(c) For rural municipal solid waste landfills serving a population equivalent of 2,500 or less and receiving little or no industrial waste, the owner or operator may conduct a survey during a representative period of operation to establish average representative weights or volumes of waste disposed. Changes in seasonal population shall be considered when establishing representative weights or volumes. Alternatively, the owner or operator may use a waste generation rate of 2 pounds per capita per day and apply it over the number of days in the reporting period. Changes in seasonal population shall be considered when applying a per capita generation rate.

(2)   Conversion factors. The conversion factors in table 4 shall be used. All conversion factors are based on wet densities. The densities provided for domestic residential waste and commercial waste in table 4 are subject to mechanical compaction, such as packer trucks or enclosed roll off containers coupled to hydraulic compactors. If the waste is loose, 200 pounds per cubic yard shall be used as the conversion factor. - See PDF for table

(3)   Department estimates. The department may estimate by waste category the number of tons received at a solid waste land disposal facility. The estimate shall appear on the certification form and shall be based on the number of tons received and reported for the previous reporting period.
