RESPONSE:d/
V I have reviewed the draft permit and determined that the proposed discharge is not located
sufficiently close to any existing or known proposed public water supply intake so as to create an
adverse effect on water quality. The DWR concurs with the issuance of this permit provided the
Permittee properly operates and maintains the facility; the Permittee meets the stated effluent limits
prior to discharge; and the discharge does not contravene the designated water quality standards.
