Any use that causes or could cause a violation of state environmental quality rules and standards will not be permitted in any zone in the city. When a use is proposed for which it is unclear whether or not it will cause such a violation, the planning staff advisor or the planning commission may require a letter from the State Department of Environmental Quality certifying whether or not the proposed use meets said rules and standards.
