Biological Transects: TO At the 30,40, 60, and SO-foot depth contours along the transect located 50 feet

down-coast of and parallel to the outfall. TO At the 20,4O, 60, and SO-foot depth contours along the transect located one miie

down-coast of and parallel to the outfall. TO At the 20.40, 60, and SO-foot depth contours along the transect located one-and-

one-half miles up-coast of and paralIel to the outfall.

It is recommended that starions be located using a land-based microwave positioning system. such as Mini-Ranger or trisponder, or a satellite positioning systern such as Global Positioning System (GPS). The high levels of accuracy and precision afforded by this type of positioning system will ensure that stations are properly located with respect to the ZID. If an alternate navigation system (e.g. Loran C) is proposed. its accuracy should be compared to that of the systems recommended herein. and any compromises in accuracy should be justified.

blonitoring station locations may be modified with the approval of the Executive Officer.

4. SURF ZONE WATER QUA4LEY biONITORING

a. Surf zone monitoring is intended to assess bacteriological conditions in areas used for body-contact activities (e.g., swimming); and to assess aesthetic conditions for general recreational uses (e.g., picnicking).

b. All "surf zone stations" shall be monitored as follows:

(1) Grab samples shall be collected and analyzed for total and fecal coliforms, and enterococcus at a minimum frequency of once per week from May 1 through October 31, and at a minimum frequency of once every other week from November 1 through April 30 of each year.

13) At the same time samples are collected from "surf zone s~ations." the foilowlng information shall be recorded: observation of wlnd (direcnon

and speed), weather (e.g., cloudy, sunny. or rainy), current (.e.g.. direction), and tidal conditions; observations of water color, discoloration, oii and grease, turbidity, odor. and matecals of sewage o n g n in the water or on the beach; and water temperature (OF).

5. INEARSHORE WATER QUALITY MONITORING

a. Nearshore monitoring is intended to assess bacteriological conditions in areas used for body-contact activities (e.g. scuba divingj and where shellfish andlor kelp may be harvested; and to assess aesthetic conditions for general boating and recreational uses.

Dear Mr. Caretto:

Receipt of monitoring reports for Order No. 95-01: NPDES No. C40107417 Facility: SERRA Ocean Outfall WDID No.: 9 000000175

This will acknowledge receipt of the February 1998 monthly monitoring report, the July - December 1997 semiannual monitoring report, and the 1997 annual' monitoring report.

The next monitoring report' due is the March 1998 monthly report.

The following comments refer to the report just received:

The February 1998 monthly reports show that total and fecal coliform and enterococcus receiving water limitations were not met at several stations. At this time we do not believe these results were attributable to the permitted discharge.

Thank you for your monitoring report submission. If you have any questions, please call Ms. Susan Pease at the above number.

Sincerely,

Pete Wilson Governor

Fecal colifonn values exceeded pem~it limits at stations SO (10% of recorded sanlples tested lligher than 400 organisnls per 100 ml), and at stations C1 and C2 (with a inonthly geometric mean greater tl1an200 organisms per 100 1111). Enterococcus values exceeded pennit linlits at statioils SO, S1, S2, S3, $5, S7, S9, S11, S13, S15, S17, S19, C1 and C2 (with a monthly geometric mean greater tllan 24 organisnls per 100 nll). Total colifonn exceeded permit liillits at stations SO, C1 and C2 (wit11 coliform densities greater than 1000 orgarisins per 100 ml). At the present time, tile Regional Board does not believe that the discharger's effluent is ca~~sing these exceedances.

General Comments:

Please report mass elnission rate (MER) values for all constituents with MER limits established in Order No. 2000-13 (e.g, settleable solids).

Receiving water analyses yielded l~igl~er fecal colifo~in values than total colifonn values in October 2000, November 2000, December 2000 and January 2001 for several Surf Zone Stations. If tl~is discrepancy is due to sample analysis standard deviation, then please include tlle standard error wit11 these values. If standard deviation camlot explain why fecal coliform values are higher tllan total colifor~n, then please provide an explanation for the discrepancy in YOLK next inonitoring report. A QA/QC investigation may be necessary to address total colifolin and fecal colifornl analyses.

The 30-day geometric means for fecal coliform and enterococcus, required by Mollitoling and Reporting Progranl No. 2000-13, were not reported. Please make the necessary changes in reporting fo~lnat to include these req~~ired values.

As you nlay be aware, the Porter-Cologne Water Quality Control Act (California Water Code [CWC]) was anended on Jan~~ary 1, 2000 to include provisions for mandatory n~ini in~~nl penalties for violations of waste discharge requirements applying to s~uface water discharges. The pertinent revisions can be foulld in CWC Section 13385(11) and (i). For t l~e purposes of CWC 13385(11)(2), a serious violation is defined as eitl~er 1) an exceedance of effluent limitations for a G r o ~ ~ p I pollutant by 40%, or 2) an exceedance of effluent limitations for a Group I1 pollutant by 20% (Group I and I1 pollutants are specified in Appendix A to Section 123.45 of Title 40 of tlle Code of Federal Regulations). For the purposes of CWC 13385(i), a violation other tl~an serious (i.e., a clu-onic violation) is defined as a11 exceedance of a waste discharge req~lirement effluent linlitation.

In accordance wit11 CWC 133SS(h) each serious violation tsiggers the assessment of a nm.ndatory l l l i i im~un penalty (MMP) in the ai~iount of $3,000. 111 accordance with CWC 13385(i), the occurrence of four clx-onic violations 111 a 6-month period will d s o trigger the assessillent of a

MMP in the amount of $3,000 for the fourth violation, and a11 additional $3,000 for each subsequellt violation. I11 other words, the fo~1rt11 clu-onic violation triggers tile assessment of a $3,000 MMP, the fifth clxollic violatien triggers the assessment of a $3,000 MMF, and so on.

SUBJECT: APRIL 2001 SUMMARY OF MONITORING FOR ORDER NO. 2000-13, NPDES PERMIT NO. CA0107417

Surface Water Unit,

No effluent violations occurred during April 2001.

Permit limits for total coliform were exceeded at surfzone sites SO, S 1, C l and C2. Permit limits for fecal coliform were exceeded at SO, S l , S2, S3, S7, C1, and C2. Permit limits for enterococcus were exceeded at SO, S1, S2, S3, S5, S7, S9, C1 and C2. A worksheet showing the calculation of fecal coliform and enterococcus geometric means is attached to this report. The microorganisms responsible for the violations are endemic to urban runoff and have no correlation to SERRA's effluent quality.

A copy of Ogden Environmental Bioassay Laboratory's report detailing the conditions and results of chronic and acute toxicity tests is attached to this report.

Very truly yours,

Dear Mr. Caretto:

RECEIPT OF MONITORING REPORTS FOR ORDER NO. 2000-13, NPDES NO. CA0107417 FACILITY: SOUTH EAST REGIONAL RECLAMATION AUP'HORITY WP)D NO.: 9 000000175

This will acknowledge receipt of the February 2001 Monthly Monitoring Report, March 2001 Monthly Monitoring Report, January-March 2001 Quarterly Monitoring Report, and the April 2001 Monthly Monitoring Report.

The next report due by July 1,2001, is the May 2001 Monthly Monitoring Report.

Comments regarding the Februarv 2001 Monthlv Monitoring Report:

1. Fecal coliform values exceeded pennit limits at receiving water sampling stations S11, S13 (10% of recorded samples tested higher than 400 organisms per 100 ml), and at receiving water sampling stations SO, S1, S2, S7, S15, C1, and C2 (with a monthly geometric mean greater than 200 organisms per 100 ml). Enterococcus values exceeded permit limits at receiving water sampling stations N1, N3, SO, S1, S2, S3, S4, S5, S6, S7, S9, S l l , S13, S15, S17, C1, and C2 (with a monthly geometric mean greater than 24 organisms per 100 ml). Total coliform exceeded pennit limits at receiving water sampling stations SO, S1, S2, S3, S5, S6, S7, S9, S11, S13, S15, S17, C1, and C2 with coliform densities greater than 1,000 organisms per 100 ml. At the present time, the Regional Board does not believe that the discharger's effluent is causing these exceedances. Coliform concentrations closest to the outfall are withn the limits established in Order No. 2000-13.

2. Effluent CBOD was not reported on a daily basis as required by Monitoring and Reporting Program No. 2000-13. If five sample results are not reported for any 7-day period when there is flow, it will be considered an omission of information. This is a violation of Monitoring and Reporting Program No. 2000-13. Please talce the necessary action to prevent future monitoring discrepancies from occurring.
