Council member's Gerry Krage and Pam Eyden were seeking to extend the year long moratorium that will expire March 13th.
Despite the City Attorney's recommendation that extending the moritorium could lead to legal challenges, Krage believes it's in the best interest of the city to wait for more answers about the frac sand industry.
Councilman Al Thurley spoke against the extension because the city could be held liable if they don't follow the legal course of action.
Last month the council unanimously approved a resolution of support for establishment of state standards related to the silica sand industry.
Krage and Eyden cast the only yes votes for the extension.
In other business, the council by consensus instructed the Planning Commission to further study air quality issues concenring silica sand. And they are being asked to establish a baseline study of current air quality and the cost of implimenting an air monitoring system.
