Bion Environmental Technologies, Inc. ('Bion') (Pink Sheets: BNET) announced the following today:



* On December 23, 2005 Bion closed an offering of its restricted and



legended common stock at a price of $4.00 per share that raised



$1,167,000 (before offering costs). The offering proceeds will be added



to Bion's working capital. As of this date, Bion has 8,385,999 shares of



common stock outstanding.



* Bion received a letter dated December 14, 2005 from the San Joaquin



Valley Air Pollution Control District ('District') in California, which



stated in part "... the District has preliminarily determined that the



Bion NMS technology is an approvable VOC (volatile organic compound) and



NH3 (ammonia) control option for dairies and has the potential of



reducing H2S emissions (hydrogen sulfide) ..." based on the District's



review of third party peer-reviewed data from Bion's DeVries Dairy/Texas



installation (see http://www.biontech.com). Further, while approval of



installations based on Bion's technology in the District will be subject



to site-specific review, the letter stated that "the District supports



the BION NMS technology assuming the claimed emission reductions from



your technology are accurate. Emission data demonstrating the efficiency



of this system will be required to confirm the proposed reductions.



This data can be obtained following the installation of the technology."



During follow-up calls with personnel of the District, the District



indicated that the Bion technology is a 'welcome addition' that it



believes will 'prove helpful in meeting the challenges facing the



California dairy industry related to compliance with air and water



quality standards.' Based on our confidence in the emission reductions



which Bion's technology produces (as demonstrated at the DeVries



installation), Bion intends to proceed towards an initial dairy



installation in California during 2006 with the filing of a



site-specific application targeted for the first quarter of 2006.



* On December 2, 2005 Bion engaged GHP Horwath, P.C. of Denver, Colorado,



a member of Horwath International Association, as its independent



auditor. Bion views this engagement as a step toward the company making



filings with the U.S. Securities & Exchange Commission later in 2006 and



establishing a trading market for its stock on NASDAQ or another



exchange.



About Bion: Bion Environmental Technologies, Inc.'s patented and proprietary technology for large dairy farms (as well as swine and other animal facilities) mitigates the nutrient releases to water and gaseous emissions to air created by the waste streams of such operations while enabling profitable integration of renewable energy production (methane & ethanol).
