We have identified several areas of concern as potentially significatt adverse impacts as a result of this quarry project. Please refer to the. enclosed Environmental checklist form and discussion for this 'list of pate,n;tial impacts. Therefore, adequate solutions to these impacts must be formulated and required by the county if tho project approval, is granted. Suitable conditions are necessary. prior -tothe granting of a negative, declaratiax� regarding ennzriraumenta impact. Otherwise, the Calif;ovni;a Environmental Quality Act requires that an environmental impact' report be ,prepared. please inform, o°ur department in writing of your proposed zblutions to these potential problems- which we can then attach to' the project as required Mitigation Measures. A few suggested methods are listed below. You should suggest others as well. Without adequate mitigation of project impacts, an Environ- mental Impact Report will be necessary, according to th;, California Envirorunental Quality Act guideli a ' Csection 15081 and 15082).
