Effective emergency preparedness and response benefits from the implementation of the Incident Command System (ICS) to improve the efficiency and effectiveness of emergency responses associated with Oil and Gas exploration and production (E&P) and preserve corporate integrity and reputation. Succesful Implementation of the ICS on fires, natural disasters, and acts of terrorism highlight the need to incorporate ICS in all Oil and Gas Incidents such as well blowouts, fires, personnel injuries, pipeline ruptures, spills and uncontrolled releases particularly those associated with the recent onshore shale oil and gas boom, which bring E&P operations close to residential areas. The ICS, developed by the US Forest Services in the 1970s and now used by most first responders, is a standardized emergency management system with proven key concepts that reduce costs, establishes objectives, mitigates environmental and human impacts, reduces recovery time, and preserves corporate image and intergrity. This paper describes the benefits of ICS, and provides recommendations for incorporating ICS into Emergency Response Plans (ERPs), training, practice drills, and actual incidents. It will show how ICS key concepts, such as management by objectives, communications, chain of command, span of control, and unity of command, should be incorporated into ERPs.

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, mandates evaluation of remediation alternative using nine criteria: (1) overall protection of human health and the environment, (2) compliance with ARARs (applicable or relevant and appropriate standards), (3) long-term effectiveness and permanence, (4) reduction of toxicity, mobility or volume, (5) short-term effectiveness, (6) implementability, (7) cost, (8) state acceptance, and (9) community acceptance. Many states have adopted these or similar criteria for remedy selection under state laws. Although not explicitly addressed in the CERCLA criteria, consideration of sustainability can be incorporated into these criteria. This paper explores how sustainability can be evaluated for remedy selection using the CERCLA criteria. Copyright © 2015 by SME. Source

The western prairie fringed-orchid is a rare North American orchid restricted to a few remnants of wet to mesic tallgrass prairie. It is federally listed in both Canada and the United States and both countries have developed a recovery plan for the species. Two key management objectives are to monitor population trends and identify beneficial management practices. We used 21 y of data from the Manitoba metapopulation to assess effects of weather and land management on this species. Our results suggest the metapopulation in Manitoba is relatively stable. Western prairie fringed-orchids appear to benefit most from a combination of warm temperatures in the previous growing season followed by cool snowy but short winters and wet springs. Periodic burning (e.g., every 2-3 y) may benefit fringed-orchids, whereas grazing may be detrimental. This was not a controlled experiment, however, and gaps in the data may have influenced our results. Prescribed burning is a viable management tool for curtailing woody invasion and both burning and grazing reduce litter and grass cover, but careful consideration of timing, frequency, and intensity of application is required so management does not hinder fringed-orchid reproduction or reduce survival, while also recognizing management requirements may vary among years depending on weather. Long-term studies are particularly valuable for the western prairie fringed-orchid due to its erratic life cycle and fluctuating populations, which complicate studies of environmental and management effects on this species. © 2015 American Midland Naturalist.

Ramps (or declines) are often used in underground mines to transport ore, waste, materials, and personnel. This paper studies mine ramp productivity and presents results from a set of computer simulations designed to model the fundamental behaviours of ramp haulage systems. Simulations show that, under fundamental assumptions without random disturbances, the haulage system always converges to a periodic behaviour in the steady state, but that productivities vary between equilibria. Simulations also demonstrate how productivity per vehicle does not necessarily decrease as more vehicles are added and, for example, in the five-vehicle case, how a 3.1% improvement can be achieved over the use of four vehicles. The result reveals the inefficiency of commonly-used lockout-style vehicle coordination strategies, and suggests a possible avenue for improving the productivity of haulage ramps by controlling the system to achieve more productive behaviours. © 2015 Published by Elsevier B.V. on behalf of China University of Mining and Technology.

The White King / Lucky Lass Superfund site consists of two former uranium mines in south-central Oregon. The remedy included consolidating two large mining overburden stockpiles that contained low levels of radioactivity and heavy metals by moving over 700,000 cubic yards of material and then capping the combined stockpile. An innovative armored cap design was used to minimize the stockpile footprint and thereby prevent disturbing existing wetlands. In addition, the stockpile was designed to merge into the surrounding topography. The remedy also included stream restoration and development of new wetlands. The stream was returned to its pre-mining channel, with the addition of hydraulic features to create new wetlands. The wetlands have greatly enhanced the ecological value of the remedy and the site.
