As discussed in detail in the March 2003 Issue of EM, the U.S. Environmental Protection Agency (EPA) promulgated a series of reforms to its New Source Review (NSR) permitting program starting on December 31, 2002. These reforms are commonly referred to as “NSR reform.” EPA asserts that the reforms reduce administrative burden, maximize operating flexibility, improve environmental quality, provide additional certainty, and promote administrative efficiency. Whether EPA’s assertions are accurate has been the subject of considerable debate, but the agency arguably did not achieve one of its original goals of eliminating program complexity. In fact, the reforms did not eliminate anything substantive from the NSR program.
Rainwater tanks in modern cities: a review of current practices and research
Rainwater tanks often provide a reliable and affordable water supply source in rural and remote areas where piped water supply systems are unfeasible due to economic considerations. However, over recent decades there has been an increase in the adoption of rainwater harvesting as part of the water supply source mix in modern cities. The uptake of rainwater harvesting has been influenced by the rise of ecological sustainable development as a mainstream practice. Rainwater harvesting is now implemented as part of...
Acoustically induced vibration: A review of industry best practice
WKC Partner and Noise and Vibration practice leader, Richard Palmer, has recently had an article published in the Institute of Acoustics (IOA) Journal titled ‘Acoustically Induced Vibration: A Review of Industry Best Practice’. This technical paper, which provides the reader with a better understanding of the AIV phenomenon, was published in the IOA Journal in September 2015. The full article can be viewed following the link below.Failure of piping systems in the oil, gas and petrochemical sectors can...
Disease-causing bacteria made more resilient by standard water disinfection practices
Halogenated nitrogenous disinfection by-products (N-DBPs) in water increase bacterial resistance to antibiotics, new research shows. The study found that a strain of bacteria which can cause disease in humans, Pseudomonas aeruginosa, increased its resistance to a range of different antibiotics by an average of 5.5 times after the bacteria were exposed to chemicals which form as by-products of common water treatment procedures. The results highlight the risks to public health which these currently unregulated...

Sharing Best Practices in Mining Safety
In the world of environmental, health and safety, sharing information can have an amazing ripple effect across an industry. It gives companies the ability to learn from the experiences of other companies. In some cases, this can be the difference between life and death for workers, or it can prevent devastating environmental incidents. Overall, we are stronger when we work together towards EHS excellence. More Collaboration Desired in Ontario Mining Sector The mining sector is an example of an industry that...
