Section 18810.7 - Determining Origin of Waste at a Landfill(a) An operator shall determine the origin of all solid waste during the origin survey period set forth in section 18810.6.(b) For every load of solid waste received during the entire quarter, an operator shall record the jurisdiction of origin for all beneficial reuse material accepted. An operator shall also record the types and quantities of material being used as alternative daily, alternative intermediate cover, and other beneficial reuse. Each type of material used for alternative daily cover, alternative intermediate cover, and other beneficial reuse shall be allocated to jurisdictions using a reasonable estimation method. A reasonable method for calculating allocations may include: (1) Determining each jurisdiction's percentage of each material type accepted and multiplying by: (A) the total amounts of alternative daily cover used,(B) the total amounts of alternative intermediate cover used, and/or(C) the total amounts of other beneficial reuse material used.(c) For every load received during the entire quarter, an operator shall track the tons of each of the following types of solid waste disposed at the landfill, allocated to each jurisdiction: (1) C&D debris/inert debris,(2) designated waste, by material type, and(d) For all loads not delivered by public contract haulers, an operator shall obtain and maintain a record of the following information:(1) the jurisdiction of origin of the waste as set forth in 18810.5, and(2) other additional information that the operator has determined will ensure that information provided is accurate.(e) An operator shall collect jurisdiction of origin from public contract haulers. The public contract hauler shall provide the jurisdiction of origin as specified in section 18808.7(b).(f) If a landfill accepts solid waste from only one jurisdiction, the operator shall assign all the waste to that jurisdiction.(g) If an attendant is not present during regular hours of operation, and one cannot be present for the origin survey period set forth in section 18810.6, and the operator does not receive origin information from the haulers delivering waste, then the operator shall assign the waste to the jurisdiction in which the landfill is located by labeling it as "no attendant host assigned" waste. An operator shall report to the agency, the total amounts of solid waste assigned to the host jurisdiction pursuant to 18810.9(c). An operator shall also provide information on host assigned waste to a host jurisdiction if requested pursuant to section 18810.9(g).(h) If solid waste is delivered to the facility and information on the jurisdiction of origin is not provided by the delivering hauler or operator as specified in this Article, then the operator shall assign the waste to the jurisdiction in which the landfill is located by labeling it as "host assigned" waste and send written notification to the agency regarding hauler or operator non-compliance as specified in section 18810.11. An operator shall report to the agency, the total amounts of solid waste assigned to the host jurisdiction pursuant to 18810.9(c). An operator shall also provide information on host assigned waste to a host jurisdiction if requested pursuant to section 18810.9(g).(i) If a landfill conducts continuous daily origin surveys as set forth in section 18810.6(a) and accepts solid waste from more than one jurisdiction, then the operator shall assign the waste tonnage based on the actual jurisdiction of origin information reported by haulers and station operators. If a landfill also conducts origin surveys for uncompacted loads of 12 cubic yards or less during at least a one-week per quarter survey period, the operator shall estimate the amount of waste assigned to each jurisdiction as described in subsection (k) and add these tonnage allocations to the tonnage allocations that were based on daily origin survey information.(j) If a landfill in a rural jurisdiction accepts solid waste from more than one jurisdiction and only conducts origin surveys during one week per quarter as set forth in section 18810.6(b), the operator shall do the following steps in order: (1) Obtain information on the jurisdiction(s) of origin for each load of solid waste delivered to the landfill on the dates set forth in section 18810.6(b). Example:
Four loads delivered during the survey week.
Load 1 = 5 tons from City A
Load 2 = 5 tons from City B
Load 3 = 10 tons from City C
Load 4 = 5 tons from City B
(2) Calculate the tons of solid waste (other than soil used as cover or for other on-site uses) assigned to each jurisdiction during the survey week. The operator shall either add up the amounts accepted from each jurisdiction, or the amounts of solid waste from each jurisdiction after adjusting for diversion activity at the landfill. Example:
City A = 5 tons (Load 1)
City B = 10 tons (Load 2 + Load 4)
City C = 10 tons (Load 3)
(3) Calculate the percentage of waste assigned to each jurisdiction during the survey week by dividing the tons determined in paragraph (2) by the total tons of waste for the survey period. Example:
25 tons delivered during the survey week.
City A = 5 tons/25 tons = 0.2 (20%)
City B = 10 tons/25 tons = 0.4 (40%)
City C = 10 tons/25 tons = 0.4 (40%)
(4) Calculate the number of tons disposed from each jurisdiction during the quarter by multiplying the percentage from paragraph (3) with the total number of tons of solid waste disposed in each quarter from section 18810.9(a). Example:
1000 tons disposed during quarter.
City A = 0.2 x 1000 tons = 200 tons
City B = 0.4 x 1000 tons = 400 tons
City C = 0.4 x 1000 tons = 400 tons
(k) If an operator conducts origin surveys of each uncompacted load of solid waste with a volume of 12 cubic yards or less during a one-week survey period each quarter pursuant to section 18810.6(c), then the operator shall calculate the estimated tons of solid waste delivered in these loads from each jurisdiction for the quarter. The calculated tonnage allocations shall be based on the actual origin information reported by haulers during the survey period. The operator shall do the following steps in order. (1) Obtain information on the jurisdiction(s) of origin for each uncompacted load with a volume of 12 cubic yards or less delivered to the landfill on the dates set forth in section 18810.6(c). Example:
Four uncompacted loads of 12 cubic yards or less delivered during the survey week.
Load 1 = 0.5 ton from City A
Load 2 = 0.5 ton from City B
Load 3 = 0.5 ton from City C
Load 4 = 0.5 ton from City B
(2) Calculate the tons of solid waste (other than soil used as cover or for other on-site uses) delivered in uncompacted loads of 12 cubic yards or less assigned to each jurisdiction during the survey week. The operator shall either add up the amounts accepted from each jurisdiction, or the amounts of solid waste from each jurisdiction after adjusting for diversion activity at the landfill. Example:
City A = 0.5 ton (Load 1)
City B = 1 ton (Load 2 + Load 4)
City C = 0.5 ton (Load 3)
(3) Calculate the percentage of solid waste assigned to each jurisdiction during the survey week by dividing the tons determined in paragraph (2) by the total tons of solid waste delivered in uncompacted loads of 12 cubic yards or less during the survey week. Example:
2 tons delivered in uncompacted loads of 12 cubic yards or less during survey week.
City A = 0.5 ton/2 tons = 0.25 (25%)
City B = 1 ton/2 tons = 0.5 (50%)
City C = 0.5 ton/2 tons = 0.25 (25%)
(4) Calculate the number of tons delivered in uncompacted loads of 12 cubic yards or less and disposed from each jurisdiction during the quarter by multiplying the percentages from paragraph (3) with the total tons of solid waste disposed during the quarter that were delivered in uncompacted loads of 12 cubic yards or less. Example:
100 tons delivered in uncompacted loads of 12 cubic yards or less and disposed during the quarter.
City A = 0.25 X 100 tons = 25 tons
City B = 0.5 X 100 tons = 50 tons
City C = 0.25 X 100 tons = 25 tons
