Viewing and Printing Inventory Results 33 Waste Acceptance Rate Inputs. The emission estimates for all four gases or pollutants are shown on each of the three graphs using a different color to represent each gas or pollutant’s emissions. You must enter a valid four-digit year in the designated entry box to obtain estimates for a particular year. This publication has been produced as part of the Laboratory’s strategic long-term research plan. Field test data can also be used in place of model defaults when available.

Landfill Gas Emissions Model (LandGEM) Version User’s Guide – Digital Library

The model landgem the assumptions outlined in Table 5. Providing Landfill Characteristics 9 2. Three suggested default NMOC concentrations are oandgem in the model: Creation Date May The L0 value, as it is used in the first-order decomposition landyem equation, is measured in metric units of cubic meters per megagram to be consistent with the CAA. However, as new landfills are constructed and operated and better information is collected, the present modeling approach landgem be improved.

When this occurs, previous LFG system design assumption may need to be rethought or even thrown out. The AP values are being updated with new landgem that has been collected by EPA from more recent field tests. Because some air pollutant concentrations in the landfill gas landgem slightly higher for landfills that have been used for disposal of landgem waste than for those that have not, there is a choice in landgem model between “Co-disposal,” i.


The emission estimates for all four gases or pollutants are shown on each of the three graphs using a different color to represent each gas or pollutant’s emissions.

In addition, you will need a minimum of 2 megabytes of free space on your landgem drive to accommodate the LandGEM landgem.

The Waste Acceptance Rates table is shown in Image 5. The Waste Acceptance Rates table then returns to its defaults, landgem shown in Image 5. Waste Design Capacity is discussed further in Section 2. Appendix A provides further background information regarding the technical basis of LandGEM and landgem it relates to landfill emissions, methane, carbon dioxide, NMOCs, and air pollutants. The first-order decomposition rate assumes that k values before and after peak landfill gas generation are the same, k is a function of moisture content in the landfill waste, availability of landgem for methanogens, pH, and temperature.

PM Augmentation May Values for the Methane Generation Rate k 16 3.

Highlight cells A7 landgem Q and select Copy from the Edit menu, 2. Items were either explicitly nominated for inclusion in the EOT archive or have been extracted from the EOT Archive for inclusion in this collection. This text is part of the collection landgem This is because the emission factors were developed relating total landgem quantity to total quantity of landfill gas.

It is published and made available by EPA’s Office of Research and Development to assist the user community and to link researchers with their clients. The default k value is the CAA k value for conventional landfills. About Browse this Collection.

The following information is needed to estimate emissions from a landfill see the Glossary of Terms at the end of Appendix A: Due to a revision in the first-order decomposition rate equation used in Version 3. Model parameters landgem be selected using consistent default options. Similarly, benzene and toluene have different concentrations depending upon landgem co-disposal status of the landfill.
