In 2007, the United States Environmental Protection Agency (EPA) enacted requirements to significantly reduce harmful exhaust emissions. To achieve this standard, Cummins and other diesel engine manufacturers developed an aftertreatment system that includes the use of a diesel particulate filter (DPF).
DPF filters go through a regeneration process which removes this soot and lowers the filter pressure. There are three types of regeneration: passive, active, and forced. Passive regeneration takes place normally while driving, when engine load and vehicle drive-cycle create temperatures that are high enough to regenerate the soot buildup on the ...
The inventory was first proposed in a 1985 New York Times op-ed piece written by David Sarokin and Warren Muir, researchers for an environmental group, Inform, Inc. [2] Congress established TRI under Section 313 of the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA), and later expanded it in the Pollution Prevention Act of 1990 (PPA).
Under the major U.S. environmental statutes—the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act, etc.--there was no mandate for the individual EPA programs to pool their data to create complete pictures of a facility's environmental footprint. FRS accomplishes this by matching the various program system records ...
Title 40 is a part of the United States Code of Federal Regulations.Title 40 arranges mainly environmental regulations that were promulgated by the US Environmental Protection Agency (EPA), based on the provisions of United States laws (statutes of the U.S. Federal Code).
In the United States, emissions standards are managed by the Environmental Protection Agency (EPA). It uses tiers to identify emission standards for cars, trucks and other motor vehicles. [ 8 ] In 2014, the EPA published its "Tier 3" standards for these vehicles, which tightened air pollution emission requirements and lowered the sulfur content ...
Each CDRL data item should be linked directly to statement of work (SOW) tasks and managed by the program office data manager. Data requirements can also be identified in the contract via special contract clauses (e.g., DFARS), which define special data provisions such as rights in data, warranty, etc. SOW guidance of MIL-HDBK-245D describes ...
Design for the environment (DfE) is a design approach to reduce the overall human health and environmental impact of a product, process or service, where impacts are considered across its life cycle. Different software tools have been developed to assist designers in finding optimized products or processes/services.
