Schem-OrWTP 13-0109.doc

Dear Susan,

Thank you for the opportunity to comment on the amendment to the NPDES Permit for the East Bay

Municipal Utility District (EBMUD) Orinda Water Treatment Plant.

Thank you also for taking the time to understand our operating processes and concerns while you were

developing the amendment.

The amendment is acceptable as is; however, we would like to suggest the following revisions:

Please correct spelling of Mokelumne Aqueducts (see pages 1, F-1, and F-2).

Page F-2, first paragraph, last sentence: replace “Discharge Point E-004 is only used duringrare water transfers to discharge excess raw water” with “Discharge Point E-004 is for rawwater transfers from other sources.”

Page F-12, Table F-2 (Beneficial Uses of San Pablo Creek and San Pablo Reservoir): revisetable so that it is consistent with Order No. R2-2009-0067 (Table F-6) or the current BasinPlan (Table 2-1). Also, as per the Basin Plan, include the following qualifier for REC-1: “Waterquality objectives apply; water contact recreation is prohibited or limited to protect publichealth.”

Replace Attachment B with the new figure (below) since Emergency Response Vehicle 972 is

no longer in service.

Replace Attachment C with the new figure (below) since the discharge for E-001 originatescloser to the confluence rapid mixer (rather than by the north rapid mixer). Also, for simplicity,

we’ve removed the “supernatant” label and changed the labels from “excess raw water” to “rawwater” and “raw water transfers” to “raw water.”

Sincerely,

Susan

Below is the revised Site Layout (new).

The 1/14/13 schematic was the final, but here it is again

From: Suzuki, Susan [mailto:ssuzuki@ebmud.com] Sent: Monday, January 14, 2013 8:19 AMTo: Teefy, SusanCc: Glendening, Susan@WaterboardsSubject: RE: Comments on EBMUD OrWTP Tentative Order

I agree, thank you.

The schematic is a quick fix (see below)… I also changed “ammonia” to “ammonium hydroxide” so it’s

consistent with the site layout.

The site layout could take awhile depending on Graphic Design’s schedule… so as far as the NPDES

permit amendment, we may have to be stuck with what we have (but I’ll go talk with Graphics right

away today!).

Hi Susan,

Just a minor edit in the schematic and the site layout attachments. The primary coagulant

should be shown as “polyaluminum chloride”. We are currently using Hyper+Ion 1020 from

General Chemical, but the supplier may change from year to year. Also in the list of

chemicals shown (under chemical building and administrative offices), polyaluminum

chloride should be includes along with the other chemicals.

Thanks,

Susan
