Some limitations to the success of the Low-Cost Carrier business model in India
Despite the growth in market share of Indian Low-Cost Carriers (LCCs), there are certain factors inhibiting the success of the LCC business model in India. This paper argues that the success of the LCC business model in India is limited by three exogenous factors – the lack of the concept of secondary airports, the route dispersal guidelines, and the excessively high costs of Aircraft Turbine ...

Developing new correlations and uncertainty analysis for the prediction of ground-level and maximum ground-level concentrations
The determination of Ground Level Concentration (GLC) and Maximum Ground Level Concentration (MGLC) is useful for the prediction of violations for air quality regulations. In this study, the predictions of GLC and MGLC when using different existing empirical formulas are analysed and the effect of dispersion parameters is investigated. Sensitivity analysis studies using both a first order and a ...

Air quality interventions and spatial dynamics of air pollution in Delhi and its surroundings
The paper examines the spatial distribution of air pollution in response to recent air quality regulations in Delhi, India. Air pollution was monitored at 113 sites spread across Delhi and its surrounding areas from July?December 2003. From the analysis of these data three important findings emerge. First, air pollution levels in Delhi and its surroundings were significantly higher than that ...

Update and revision of Turkish air quality regulation
The Air Quality Assurance Regulation (AQAR) was issued on October 1986. This regulation was basically a direct translation of the German TA-Luft of 1984. The main purpose of AQAR was to control the effect of industry, domestic heating and Traffic on ambient air quality which previously had not adequately been represented. Two new regulations, "Industry Related Air Pollution Control Regulation" ...

Empirical Analysis of National Income and SO2 Emissions in Selected European Countries
The linkage between per capita GDP and sulfur emissions for 12 Western European countries was analyzed over a period of more than 150 years. The analysis also looked at the impact of air pollution regulations on the shape of the income–pollution relationship. At both the aggregate and country levels, we find an inverted U-shaped relationship and the estimated turning points of most countries are ...

Implementing QALYs in the Analysis of Air Pollution Regulations
In recent years, there has been growing interest in cost-effectiveness analysis for environmental regulations using quality-adjusted life years as the measure of effectiveness. This paper explores the implications of the QALY approach for measuring the impacts of air pollution regulations, with an example using the U.S. Environmental Protection Agency’s Heavy Duty Engine/Diesel Fuel regulations. ...

Effect of pH on nitrate and selenate reduction in flue gas desulfurization brine using the H2-based membrane biofilm reactor (MBfR)
Increased tightening of air regulations is leading more electric utilities to install flue gas desulfurization (FGD) systems. These systems produce brine containing high concentrations of nitrate, nitrite, and selenate which must be removed before discharge. The H2-based membrane biofilm reactor (MBfR) was shown to consistently remove nitrate, nitrite, and selenate at high efficiencies. The ...

Idealized Air Quality Regulation: A One-Atmosphere Approach
After almost 40 years of experience with the U.S. Clean Air Act (CAA), many of the original goals of the regulation have been achieved. The CAA and its subsequent amendments have been driven largely by science and technology, linking the Earth’s atmosphere with public health and welfare and sources of pollution. Knowledge in the 1960s about the atmosphere that influenced air pollution has been ...

Achieving Air Pollution Control With Catalytic Or Thermal Oxidizers
As the full effect of the Federal Clean Air Act (CAA) Amendments passed by Congress in 1990 continue to impact today's industry, many manufacturing operations have become subject to stricter local, State and Federal clean air regulations. Both VOC (volatile organic compound) and HAP (hazardous air pollutant) emissions are strictly regulated since they lead to the formation of ground level ozone ...

Legal Lookout: The Shape of Things to Come at EPA
One of the first questions facing EPA in 2005 is who will be in charge. The absence of an administrator even for a short while also means that Steve Johnson, now confirmed as the deputy administrator, will continue to greatly influence not only chemical regulation and pesticide matters, given his background, but other matters involving air and water regulation. Similarly, there are ...

Determination of odorous VOCs and the risk of occupational exposure to airborne compounds at the waste water treatment plants
Concentrations of non methane-VOCs and risk levels of employees’ exposure to VOCs were determined at two Finnish waste water treatment plants. The concentration of hydrogen sulphide (H2S) reached the Finnish OEL (occupational exposure limit). The concentrations of styrene, 1,2-dichloroethane, and toluene were found to be elevated at plant A. 328.4 μg/m3 of styrene and 709.8 μg/m3 toluene was ...

Two Landmark Interpretations of the Clean Air Act
The most recent U.S. Supreme Court term is notable for two landmark interpretations of the Clean Air Act (CAA). In Massachusetts vs. EPA (U.S., No. 05-1120, 4/2/07), the court held that greenhouse gases (GHGs) are air pollutants subject to regulation under the CAA, overruling an interpretation by the Bush administration. In Environmental Defense vs. Duke Energy Corp. (U.S., No. 05-848, 4/2/07), ...
