  • Return of the clean air interstate rule—The court does CAIR

    In summer 2008, the U.S. Court of Appeals for the D.C. Circuit issued a dramatic decision to vacate the Clean Air Interstate Rule (CAIR) in its entirety (North Carolina v. EPA, No. 05-1244, D.C. Cir., July 11, 2008). Following a petition for rehearing, it seems the previous vacatur was just a temporary detour, as the Court reinstated CAIR on December 22, 2008. The reinstatement appears to turn ...

  • Air Pollution Control: Ready for the 21st Century

    The textile industry is plagued by air pollution problems which must be resolved. In particular, smoke and odor arising in the process require abatement. Air pollution control technology is available today which will serve the textile industry well into the 21st century. The nature of the problem The major air pollution problem in the textile industry occurs during the finishing stages, ...


  • EPA proposes updates to CISWI rules

    On June 4, 2010, the U.S. EPA proposed updates to the Standards of Performance for New Stationary Sources (NSPS) for Commercial and Industrial Solid Waste Incineration (CISWI) Units (NSPS Subpart CCCC) and Emission Guidelines (EG) for Existing CISWI Units (EG Subpart DDDD), collectively referred to as the "CISWI Rules." In order to describe the proposed updates to the CISWI Rules, it is necessary ...

  • New boiler MACT and affiliated rules proposed

    EPA proposed three related rules (with final rules expected by December 16, 2010), intended to reduce the emission of hazardous air pollutants (HAPs) from industrial, commercial, and institutional boilers and process heaters as well as commercial and industrial solid waste incinerators. Simultaneously, it also proposed a definition of solid waste that could potentially affect some units currently ...

  • Coupling of neural network and dispersion models: a novel methodology for air pollution models

    Supervised neural net models and dispersion models are two important approaches for evaluating air pollution concentrations. The authors propose the development of an integrated model, in order to optimise the performances of each methodology. The concentrations evaluated by an air pollution model are coupled with a Neural Net (NN), so as to adjust the influence of important variables on ...

  • Solid waste management in Patna – analyses of ambient air and ground water pollution

    Municipal Solid Waste (MSW) in Patna is disposed of in an unscientific manner without considering environmental impacts. The wastes are dumped in the low-lying areas without compliance of the MSWM Rules, 2000. The dumped wastes are mixed with biomedical wastes making it hazardous. Ambient air quality and ground water were analysed at two dump sites to study the possible impacts of MSW. The ...
