Property owners who pump water for their farms or businesses from the Paso Robles Area Groundwater Basin may soon need to pay for their groundwater. Right now, they have the opportunity to protest those fees. Residential well owners, however, won’t be charged those fees directly — which means they can’t protest them either, according to Ryan Aston, a consultant who developed the proposed rates. … The agency will hold a public hearing to consider the rates on Aug. 1. If a majority of recipients submit a written protest, the agency can’t implement the rates. Otherwise, the board can vote to enact the fees.
