This Methodology prescribes the procedures by which a provider of solid waste disposal service shall calculate a draft tariff for the provision of a solid waste disposal service at a landfill for solid waste. The merchant shall submit to the Public Utilities Commission the original of the draft tariff document (in paper format or signed by using an electronic signature according to the procedures prescribed by the laws and regulations) and the electronic form (if the original of the draft tariff has been submitted in paper format). The merchant shall, together with the draft tariff, submit documents which have been specified in the decision taken by the Regulator in relation to justification of costs forming the tariff, revealing justification for costs forming the tariffs referred to in the calculation of the draft tariff. Upon submitting the draft tariff, the merchant shall append a description reflecting the process of solid waste acceptance, mechanical biological pre-treatment and disposal at the landfill, as well as indicate the amount of the relevant activities in the previous and current year.
