"The purpose of this study was to develop a quantitative assessment of the levels of stream depletion or reduction in formation outflows (Spring flows or flowing stream systems gaining from contact with formations) that may be occurring as a result of the removal of water by coalbeds methane wells. .... The concern has been raised that the removal of ground water from aquifers that may be tributary to the surface stream system could be resulting in stream depletions or a reduction in spring flows and/or formation outflows that are of a magnitude sufficient to cause injury to senior water rights holders on over-appropriated stream systems."-- Cover letter.
The federal Clean Water Act requires that stormwater discharges from certain types of facilities be authorized under stormwater discharge permits. The goal of the stormwater permits program is to reduce the amount of pollutants entering streams, lakes and rivers as a result of runoff from residential, commercial and industrial areas. The original 1990 regulation covered municipal (i.e., publicly-owned) storm sewer systems for municipalities over 100,000 population. The regulation was expanded in 1999 to include smaller municipalities as well. This expansion of the program is referred to as Phase II.
Recent work has suggested that large amounts of anthropogenic sulfate aerosol reduce riming efficiency in some mixed-phase clouds leading to a decrease in snowfall rate. This study investigates this aerosol effect in the Colorado Park Range for four winter storm cases in February 2005.
This fact sheet provides an overview of the air quality requirements affecting oil and gas exploration and production (E&P) condensate tanks, tank batteries, engines, dehydrators and the wells serviced by these tanks and tank batteries in Colorado.
