High Plains Gas, Inc. (OTCBB: HPGS) (or "HPG" or "the Company"), a Gillette, Wyoming based energy company actively engaged in the acquisition, development and production of natural gas primarily in the Powder River Basin, today announced that it has seen a significant reduction in the amount of chlorine needed to generate a "clean water sample" by reworking the valving system on one of its water injection facilities.

Typically the water content that is pumped out of a methane gas well exceeds the iron fixing bacteria threshold required by the Wyoming State energy lab hence the need to use chemicals to treat the water before it is injected back into a natural underground aquifer.

Mark Hettinger, Chairman of High Plains Gas, commented, "By reworking the valve sequence we have increased the chlorine's contact time with the water which allows us to use significantly less chlorine per facility to achieve the same results. We are seeing roughly a 70% reduction in our chemical costs."
