NOE - Notice of Exemption

Document Description
SWRCB, as responsible agency, will be issuing a water supply permit. The city of Chino proposed project is for one treatment system piping to an existing treatment facility. The pre-filter unit is 10 ft x 15 ft ft and installed above ground with no permanent foundation. Vessels will be installed on a 17 ft x 38 ft concrete pad. New 8 in distribution piping will be installed for GAC treatment system influent, effluent, and backwash supply. The GAC treatment system will utilize GAC material that will need to be removed from the vessels every 1-3 years (varies based on water quality) and transported (non-hazardous) to an off-site location to be reactivated for reuse. The project proposes a shallow excavation to install concrete pad for the GAC Treatment Systems. No permanent grading is proposed outside project and any areas disturbed during construction will be restored to its original condition. Total disturbed area is estimated to be approx <1,000 sf.
