hearings and givetestimony regarding the accuracyand comDleteness ofthe Draft EIR. The hearings are being
held closertothe affected areas forthe convenience ofthose wishing to give oral comments on the Draft EIR; It is
not necessaryto attend more than one hearing.
All written comments and all comments received atthe public hearings will be responded to in a Comments and
Responses document, which will also contain any changesto the text of the Draft EIR. The Draft EIR, togetherwith
the Comments and Responses document, comprises the Final EIR, which the San Francisco Planning Commission
mustcertify as accurate and complete before the San Francisco Public Utilities Commission can take action on the
proposed project. Preparation of an EIR does not indicate a decision by the City eitherto carry out orapprove, or
disapprove, the Plan. Following the decision on the project, a Notice of Determination will be filed with the County
Clerk ifthe project has been approved. Aftersuch filing, there is a period of 30 days during which an appeal
contesting the EIR may betaken to court, as provided in the California Environmental Quality Act.
Forfurtherinformation concerning environmental review ofthe Chloramine Conversion project, contact Paul
Deutsch ofthe S.F. Planning Department at415-558-5965. Forfurther information concerning the chloramination
projectand process, call the SFPUC project information line at 415-557-6738.

Conversion Draft EIR
FROM: Hillary Gitelman, Environmental Review Officer
SUBJECT: Request for the final Environmental Impact Report for Hetch Hetchy Water
Treatment Chloramine Conversion Draft EIR Project (Planning Department
File No. 1998.898E)
This is the Draft ofthe Environmental Impact Report for the Hetch Hetchy Water Treatment
A
Chloramine Conversion project. public hearing will be held ofthe adequacy and accuracy
ofthis document. After the public hearing, our office will prepare and publish a document
titled "Summary ofComments and Responses" that will contain a summary of all relevant
comments on this Draft EIR and our responses to those comments. It may also specify
changes to this Draft EIR. Those who testify at the hearing on the Draft EIR will
automatically receive a copy on the Comments and Responses document, along with notice
ofthe date reserved for certification; others may receive such copies and notice on request or
by visiting our office. This Draft EIR together with the Summary ofComments and
Responses document will be considered by the City Planning Commission in an advertised
public meeting and certified as a Final EIR ifdeemed adequate.
After certification, we will modify the Draft EIR as specified by the Comments and
Responses Document and print both documents in a single publication called the Final EIR.
The Final EIR will add no new information to the combination ofthe two documents except
to reproduce the certification resolution. It will simply provide the information in one, rather
than two, documents. Therefore, ifyou receive a copy ofthe Comments and Responses in
addition to this copy ofthe Draft EIR, you will technically have a copy of the Final EIR.
We are aware that many people who receive the Draft EIR and summary ofComments and
Responses have no interest in receiving virtually the same information after the EIR has been
certified. To avoid expending money and paper needlessly, we would like to send copies of
the Final EIR to private individuals only ifthey request them. Ifyou would like a copy of the
Final EIR, therefore, please fill out and mail the postcard provided inside the back cover to
the MajorEnvironmental Analysis Office ofthe Planning Department within two weeks after
certification ofthe EIR. Any private party not requesting a Final EIR by that time will not be
mailed a copy. Public agencies on the distribution list will automatically receive a copy of
the Final EIR.
