EPA Region 9 Announces Two Landfill Gas Enforcement Settlements
One landfill agreed to pay a penalty of $215,000 US for illegally venting and mismanaging treated landfill gas. The other landfill agreed to a penalty of $196,936 US for failing to properly collect landfill gas during construction activities.
EPA New Source Performance Standards (NSPS) require landfills to collect gas that results from the biodegradation of solid waste in landfills, and to either treat the gas with a control device (such as a flare) or to route the collected gas to a treatment system that processes the gas for subsequent sale or beneficial use. Venting of treated landfill gas to the ambient air is not allowed.
Demonstration of compliance is made by measuring gas flow rates and the quality of the gas before and after it is treated or processed. Large amounts of data are generated which must be managed to properly operate the emission control systems, perform emission calculations, and file required reports with regulatory agencies.
Our Ambient Quality Management Information System, AQMIS, is the perfect solution for managing and reporting data related to landfill gas compliance. Process data can be ingested into the system using an Application Programming Interface (API). Additionally, implementation of the air modeling module can help operators manage site operations to address odor complaint issues.
Contact us today to learn more about how AQMIS can be used to resolve your air quality compliance data management and reporting responsibilities!
