Landfill Permits 

Permits Required for Operating the Landfill

Short Mountain Landfill is regulated by federal, state and local agencies to ensure that the landfill is operated in compliance with the law and in a manner that protects both humans and the environment. These permits are described in the table below:



Purpose of Permit 

 Title V Operating


Title V of the 1990 Federal Clean Air Act requires each state to develop a comprehensive operating permit program for major industrial sources of air pollution. The program clarifies the environmental obligations of a business by organizing in one document all of a business' air pollution control requirements.

 Solid Waste Disposal

 Oregon DEQ

As part of their Land Quality Program, DEQ regulates and authorizes certain solid waste management activities, including landfilling. This regulation upholds Oregon Revised Statute (ORS) Chapter 459.

 NPDES 1200Z Stormwater

 Oregon DEQ

As part of their Water Quality Program, DEQ regulates stormwater runoff from land and impervious areas, such as paved streets, since this stormwater often contains pollutants that could adversely affect water quality. This regulation upholds ORS Chapter 468B.

 Wastewater Discharge

 City of Springfield

The U.S. EPA has mandated that industrial site may not contribute pollutants or substances to the sanitary sewer system that will disrupt wastewater treatment. The City regulates industrial discharges to control the quality of the wastewater being treated.

 Agricultural Fireworks & Vector Control

 State Fire Marshall & USFW

Hazing of vectors (birds) is required to reduce the potential for the spread of disease through the scattering of garbage from the landfill by the birds. The hazing/salvage is permitted by the Migratory Bird Treaty Act.

 Wetland Fill & Removal Permits

 Oregon DSL & USACE

Because the landfill property contains wetlands, construction and expansion activities sometimes require filling or removal of material from the wetlands. These activities are regulated to ensure that these activities are done in a manner that protects navigation, fisheries and recreational uses associated with the wetlands. This regulation upholds ORS chapter 196 and the Clean Water Act Section 404. (See the Quamash Prairie section of this website for more information.)

Environmental Monitoring

Monitoring of various environmental parameters is required for obtaining and maintaining compliance with some permits. This monitoring gives the regulating agency information on how the landfill is affecting its surrounding environment. The environmental monitoring program at Short Mountain is extensive and includes groundwater, air, landfill gas and leachate sampling.



Groundwater Sampling

Sampling of the groundwater at Short Mountain occurs every 6 months. Monitoring wells, such as the one pictured here, are located around the perimeter of the site, both uphill and downhill of the landfill. By taking samples uphill of the landfill, a baseline is created for comparing the downhill samples to. This monitoring measures the affect, if any, the landfill has on the groundwater. In addition to groundwater samples, the depth to groundwater is measured every 3 months. This allows the groundwater table to be mapped for planning of future landfill expansion.



Air Sampling

A series of landfill gas wells are located around the perimeter of the landfill property. Every 3 months the air in the wells is sampled using a gas meter like the one shown to the left. This meter measures the oxygen level and LEL (Lower Explosive Limit) of the air in the wells. These two parameters show whether landfill gas is migrating from the landfill cell through the ground. All structures located on the landfill property are also tested every 3 months.




Landfill Gas Sampling


Weekly samples of the landfill gas are taken weekly from various well heads using an gas meter similar to the one shown on the right. This is done to determine the concentration of methane and carbon dioxide of the gas. This information is then used for adjusting the vacuum system that draws the gas from the landfill. It is also used for determining the amount of greenhouse gas that is being collected and destroyed by the gas system.


Leachate Sampling


Leachate samples are taken every six months in conjunction with the groundwater sampling. Three samples are taken; from the leachate holding lagoon, the secondary containment system in Cell IV and the secondary containment system in Cell V.
