Where Basin Plan objectives are stated in general terms, such as"no toxic chemicals in toxic amounts",or where specific objectives for the contaminant or pparameter of interest do not exist or if it appears that the objective is not protecting tfie beneficial use,Reggional Board staff is encouraged to consult with staff specialists in the Standards,Po1ic e and eSpecialse Studies o a quality criteria fromental/ Technical Support Units for ass istance.
