The control measures should include details relating to containment, collection and treatment of LFG. In particular the following should be considered. • • • • • • Landfill development. Emissions standards. Collection system (including the year it is proposed to start collecting LFG). Condensate management. Utilization, flaring and treatment. Inspection, maintenance and servicing. The monitoring and sampling plan should include details related to the following: • • • • • • • • Schedule for specific data collection and frequency of monitoring at all stages of the site.
Also 1 m3 CH4 can produce about 10 kWh of energy. Utilizable LFG varies in amount and sustainability for example Ukrainian towns generate 10–12 million tones of MSW per year. More than 95% of MSW is disposed at the landfills. There are 700 landfills located around the towns. Only 100 of them can be considered as potential candidates for recovery and utilization of LFG. Based on this facts, potential of LFG available for energy production comes to about 400 million m3/year. 8 billion m3/yr of gas.
During well installation only a single well may be excavated and must be completed and sealed as rapidly as possible. All wells and pipes must be equipped with valves and kept closed. Leaks in the LFG system should be detected through drops in pressure or increase in oxygen concentrations. The Environmental Management Plan (EMP) details the actions and management measures that must be implemented during each phase of the LFG to energy project. The measures should be aimed to minimise the potential negative environmental impacts (to an acceptable level of significance) and enhance the positive impacts of the LFG to energy Project.
