subject: Sediment toxicity testing requirements
Dear Sirs.,
BeloW" are additional conditions of approval of receiving "'itI'ater
study plans, as promised in cur June 8 , 1989 letter. These
conditions apply to s.ediment toxicity tests, 'W'hich 'Will
provide information regarding the impact of point and nonpoint
sources on beneficial uses in the South Bay. The info~ation
~ill be used to determine the -reasonableness· of requiring
~urt~er poi~t a~d nonpoint source controls# as stiF~lated by
the cost/flt.pact approach (la option of the 1986 Basin Plan)
for setting site-specific pollutant objectives and effluent
1 i:mitations ..
The specific q~ls Qf the sediment toxicity testing. in ordEr
of priority .. are: 1) to oe:termine spatial and te:;:-,poral
--distributions of toxicity in the South Bay. 2) to evaluate the
extent of South Bay toxicity relative to other parts of S~n
Francisco Bay ..
The field and laboratory design for toxicity testing is
sult-J!lariz.ed in Tables 1· -3. Three di-rferent tcxlcity tests
will be conducted at each station to increase the range of
sensitivities, endpoints and e:.:posure paths~ Alr,ong t.he factors

affecting test selection were reproducibility. e.rte.nt of prior
use. ecological r~levance, species sensitivity to toxicants.
and species tolerance to a range of salinitief a~d sediment
-grain size. .
The battery of tests tor each station will depend upon the
interstitial salinities at that station, and viII vary alonq
the salinity gradient from each discharge outfall (Table 1J.
We. do not expect that this will significantly reduce the
comparability of data among stations~ since the_~ajcrity of
stations will fall into the inter.mediate salinity category.
At salinities <2$ ppt you may choose to conduct either the
Microtox or echinode~ test. However. to ensure comparable
results, all l discha ... -gt:'!rs must Select t..."!e same test. In
addition, all dis~harqers must obtain a~phipods and control
sediments for solid pbase tests from the s~e source.
Adjostment of interstitial salinities by wet-sieving will not
be an acceptable procedure in solid phase tests l since this
procedure significantly disrupts the particulate-pore water
mat~ix. Instead, an ~mphipod species tolerant of the natural,
interstitial salinity at a particular station (Table 1) will
be exposed to unsieved sediment from ~hich predators and large
animals have been removed with forceps (Lamberson and Swartz,
19B8).. OVerlying: 'Water used in solid phase tests will be
clean, oceanic · .... ater {e~9., Bodega Bay sea .. -ate.r) diluted 'With
-distilled" deionized water to-match natural, interstitial
salinities.
·Salting-up· procedures (using natural seawater brine or
comJnercial seasalts) villI h-owever, be acceptable for sediment
elutriate and extract tests (mollusc embryo" echinoderm
pigment" Microtox)... despite t1le likelihood that the
bioavailability (and, therefore, the toxicity) of potential
toxicants will tle reducec!~ We e.Jqlect that this limitation
will be mitigated by running at least 3 ~ifferent types of
test at each station.. .
All tests should be conducted according to specified protocols
(Table 1).-Copies of tilese protocols are enclosed.. Bo·th
negative (~clean·) and positive (reference toxicant) controls
sbould be conducted fer all tests. In addition, c~ntrols fer
potential effects of grain-size are necessary for a:mphipod
tests. Sediments should be sample~ according to Lamberson and
Swartz" 19'39 (ASTH protocol I draft No.3). If deviations from
any protocol seem necessary, these shculd. be discussed in
advance with ~e9ional Board staff.
The station locations for toxicity testinq are similar to
those originally proposed, althcugh each discbarger ~ill

sample from one additional station (Ta~le 2). In our June a,
1,89 transmittal, 4 nev stations ~ere added to those
originally propQsed. ~o of these stations, located in Mo~ry
Sl~h. 'Were mislabel1e,j on Figure A of tnat letter as R2 and
Rl. Attacbed is a CQrrec~ed figure (Figure 1), which aaps all
stations, iT~luding t~e 4 new stations, labelled as S86, S87.
Poe and RS.
The n·uml:ler of separa.te field samples c::lllected at each station
has been increased from 1 to 2-5, depending upon the station
(Table 2). However, the number of laboratory replicates per
field sample has l:leen reduced from 5 tOo o. This sampling
desi9n, which provides an estimate of field variability at the
expense of analytical variability,. enables statistical
comparisons amonq sta~i¢n ~roupings O~ habita~ types (Table
3) that could not have been obtained. 'Wi th the pre'posed design.
According to this design~ 5 samples (field replicates} ~ill
be collected from each station grouping. It is assumed that
the analytical variability for t~e selected tests is
relatively small and 'Will net confound results of this
toxicity survey.
Sediment toxicity sa~ples will be sub-sampled trom sediment
chemistry samples, as sp~ci!!ed in ~~r June S letter.
However. since only 3 field replicates are required for
cbemical analysis, 2 additional samples fer c!'J.e-:nical anal,)'sis
will be ne2ded trom cert3in stations during sacpling periods
when toxicity testing is t.o be c~nducted.. specifically.
additional sediment ehemistrI will be needed for 3 San Jose
stations.., 2 sunnyvale stations and 1 Palo Alto station.
All stations will be sampled t· ... ice per dry season (J'uly -
Septemrer) ar~ twice per ~et seascn (Oecember -February) tor
one study ye.ar. H-oW'ever, you must submit a report that
includes raw data ... data 5~ari-es and statistical. analyses
afte.r the first 2 sa.mple runs (one dry season) hav~ been
completed. This in.form.ation will be used to detenaine if
modifications in sa:mpiilq design are n.o:cessary. Kcditicat!.ons
will not siqnficantly increase the study effort.
According to this scnedule" t..~e toxicity studies will be
completed ):ly February 1990. We recoIrJ'l',end that you submit a
proposal Cor further toxicity testing (ambient water column~
sediment" or both) by F~bruary. 1990.
Oata for individual tests sbould be s~arized and analyzed
according t.o the protocols tor those tests. R~W' data tor all
tests must be also be submitted. Additional analyses eosing
ANOVAJ which compare toxicity among stations groupings (Table
3) sbould also be ~rovided.

Subject: NPDES Receiving Water Monitoring Studies
Dear Sirs:
This letter responds t~ correspondence from San Jose/santa Clara
(6/29/89). Sunnyvale (6/30/89) and Palo Alto (7110189) regarding"
special receiving 'Water st'Udies. Since the content of those
letters overlaps considerably .. a single response is most expedient.
Most .of t.he con-.::erns 'iIIere addressed by Regional Board st~ff at July
11 and July 17 meetings attended by representatives of all three
dischargers .. This cOIJ".IDunication 'Will .. therefore. focus on three
specific areas that ~ere left unresolved: bioaccumulation studies,
dj',e studies, and sedi'I:1erlt toxicity surveys. Questio!".s raise-::i by
Palo Alto regarding the UEe of receiving' vater study data in
performing a vaste load allocaticn will be discussed at a future
time ..
~ll ) di scbargers have questioned the value of laooratory
bioaccu~ulation studies ~s a preliminary to field studies. During
the July 11 Ir.eeting your consultants presented a joint proposal for
a field study ... ihich involved transplanting bogged mussels (~!-i!u.:~
cali .. .t:.q .. J::".n.l.<mus) to 6 locations in the South Bay once during the dry
season, 138~. The field study vould take the place of laborato~y
studies required by my June 8, 1989 letter ..
•
", ,
•
I
! ,
'.-'-";.
o
We accept your z,os't recent bioacculllulation study proposal .. with
minor modifications. rhe 5tud~ design is as follows:
o Field testing yill be conducted once during the 198~
dry season a Oata from this testi1\9 'Will be 'Used to
deter.mine the need for a wet 5eas~n (19S9-90) samplinq.
We recomlllend that further bioacCUlllulation sampling be
incl uded in the second round of study proposals on
impacts to beneficial uses 4ue on February 1,1990.
o Instead of the six stations you proposed, we require seven
stations at the following locations .. as discussed 'With your
consulta.nts:
-The power lines that cross Coyote Creek~ adjacent to
C-6-0
The gate that is near the mooth of Guadalupe Slough
-The tll channel marker .. near SB6
-Palo Alto Station Ie
-SB4
-The naviqational aid located Offshore of Coyote Point
The San Bruno shoals
o Bagged bivalves should be used to test bicaccumulation at
these stations following the procedures of the Mussel Watch
Program.
o Three replicate samples sbould be taken at each station.
All of you have raised questions about how bioaccumulation data
will be used by the Regional Board in settirl9 sit.e-specific
objectives and limits for the South Bay, according to the cost
impact approach. As you know, the value of bioaccumulation ~ata
is presently limit.ed by ~ lack of st~ndards for interpretinq the
biological significance af body burdens of contaminants. In the
abse.nce of specific standards. Regional Board staff ,..il1 use
biomonitoring: data from South Bay receiving-water studies in a
comparative way.. Tt~sue contaminant levels 'Will be compared ",'ith
levels in biota sampled from other areas of San Frar~isco Bay or
other estuaries. This will enabl~ us to tarqet areas of qreatest
potential impact for purposes of focusing recommendations for
further source control.. One requirement of the cost-impact
approach is tbat all reas~nable sourCe control measures be
implemented.
An additional use of the South Bay biomonitoring data will be to
provide info~ation tor setting station locations for the proposed
San Fran~isco Bay regional monitoring program. Biomonitors will
be an iY1por-tant part of this regional effort, as they provide
information that cannot be obtained from ~ater colu~ and sediment
monitoring. In particular, biomo-nitors integrate contaft'.inant
levels over time and enable an assessment of bioavailability. This

in!o~ation will improve our understanding of the fate. transport
and tlio3.vailabillty of contau:"inants in this estuary.
RYe Studies
Dye studies viI! still be required tor San Jose/Santa Clara and,
possibly, Palo Alto. Tbese studies will no lonqer be used in
conjonctio-n with laboratory bloaccUlllulation studies to tarqet field
bioaccumulation sites. Instead l they will be an inte9ral part of
the Regional Board's Effluent and ~1ent ~oxiclty Testing
Programs.. For-a discussion of the ant-icipated need fer these.
ambient to¥icity studies in the South Bay, we reter you to Item 11
of the July 19. 1989 meeting of the Regional Board, a copy of ~hich
was recently mailed to each of you. Please contact or~ Susan
l'merson of ,.y staff C4l5-46~-13461 to discllss the tiaing and
coordination ot dye studies with ambient toxicity testinqp
presently 5cbeduled for september. Also, contact Or. Tom Mumley
(415-464-0962) to discuss the specific des19n of the dye studies.
This requirement does not apply to the City of Sunnyvale, since
ambient toxicity testing in conjunction with a dye .tudy .. as
recently conducted.
~~jm~nt Toxi_~esting
We do not accept your most recent (~uly 11) proposal for sediment
toxicity test.i"9, which 'Would reduce the testing: program due to
budget limitations ~nd technical concerns a1?out test protocols ..
You have proposed to conduct pilot elutrlate. and solid phase
toxicity tests at a total of six stations once 4urlng t.he dry
season, 15189. According to your proposal, revie.w of these
preliminary data would determine the need for further testinq. In
aQdition~ you have proposed a preliminary study to determine if
grain size/salinity interaction3 could jeopardize the bealth of the
solid phase bioassay orqanism EOh~ustauriu5, thereby confounding
the interpretation of test. results.
We conclude that your proposed pilot testing will not provide a
sufficient basis for focussIng subsequent to~icity studies~
However~ data review after the first toxicity survey is warranted,
so 'We are requiring only one toxicity survey during tbe curre.nt
(1989] dry season. ~aw data and results of statistical analyse.s
~ust be submitted to the Regional Board at the earliest possible
date, but no later U,an November 1, 1989a This deacUine is
necessary in order to insure adequate time for review before the
on~et of the wet season (December -February). TVo 5urveys 'Will
be run during the. 'We.t seascn~ unless the data review indicates that
this is not advlseable. You may be required to conduct a second
dry season survey in 1990, to replace the one lost by this season's

letter have ~ell established protoc~ls, and have been previously
used in San Francisco Say, vith the exception of the EQhaust~urius
solid phase test and the t~o freshwater tes~s, ~bich have been used
extensively e15ewhere~ Furthermore. the protocol for the
EohaqstaurilJs t.est is nearly identical to the protocol for the
extensively used Rh~p9xynius test, ~ith the exception that
overlying water v111 ~atch interstitial salinities in test
sediments.. Therefore.. special laboratory preparation for
conducting the E'o'hagstOIJr-igs test will no-t be necessary.. The
rationale for selecting this test over other solid phase tests ~as
presented in the June 20 letter. Please consult a recent NOAA
Technical Memorandum (NOS OMA 45, 1989] for a positive evaluation
of the suitability of the Rhepoxynip$, Mytilu5, ~nd sea urchin
tests as indicators of toxicity in San Francisco Bay_
You have raised a legitimate co~cern about the potential effects
of salinity and grain size on contr~l performance in the
Eohaustaurius solId phase test. Although previous york has sh~vn
that the sensitivity of ~~t!!ltlritls to the org!!lnic compound,
fluoranthene, does not change over a wice range of salinities, the
response to metals may be different. I~ addition, the interaction
bet'Ween salinity and grain size could .. potentially .. modify the
response, althouqh this has not been demGnstrated for any species.
However, a well-desiqned experiment to test this hypothesis would
require 6-12 months and participation by researchers ~ith specific
expertise in this area. Alternatively, these concerns can be
adequately addressed by incorporating appropriate controls during
toxicity testing and by ~sing ~ethods of data analysis to
compensate for potential effects, as follo~s.
o We strongly recommend that t'Wo reference toxicant
controls" using cadmium. chloride, be conducted et the
extreme ends of the interstitial salinity qradient
encountered at bioassay stations for vhich tohaustauxju§
'Will be used as a test species. Since free. ion
concentrations of metals are positively correlated wit}.
toxicity and negativity ~orrelated with salinity, it is
i~portant that the dilution series for the two reference
toxicant controls be ~atched 'With respect to free ion,
r~ther than total cadmium concentration. Please check
with ~y staff if you have questions about the correct
preparation of reference toxicant solutio·ns. You may
also \fish to conauct qrain size <;ontrols at the two
elltreme salinities encountered in the field. Wet sieving
of grain size control sediments to achieve desired
interstitial salinites Is an acceptable proceoure.
o statistical methods for dealing \fith potential effects
of grain size on control survival are described in DeWitt
(in press, 1989), and yere discussed with your
conSUltants at the July 18, 1989 me~ting. The methods
-"_IiIC:,,',,., .. all',..' '""",WioC> ... ,:,,,"':''"'-~,"'!!.,-:

involve computation of a 55' prediction-leval tor etfects
of qraln IIze alone~ This level can be used as an
additional atandard against whieh response to south 8ay
cedirenta 1s compared.
In conclusion.. we wIsb to emphasize that tbe magnitude. and
co~plexity of these r.c.ivl~ vater studies necessitates frequent
communIcation, cooperatioJ1, and flexibility on the part of all
participants. Discharqers should expect that modifications of
study design and approach vill occur during the planning and
execution phases as problems are encountered or new information
becomes availa.ble. These modifications should be vieve!5: in a
positive liqht in that they viIi result in more efficient use of
study funds and more useful study results.
Thank you for your eftorts to date in developing these receiving
vatar studies. We look forward: to \lorkill9 \lith you during the.
execution of these studies to insure that meaningful information
is obtai ned.
If you have further questlo-ns ... do not hesitate to contact Cheryl

Catwalk. .t Discharge 4) were not concurrenl Instead, an interval of 5 day.
separate.:! t.'le test initiation dates.
o The Eohaustaurius tests for Sta600s 1 and :!-3 were conducted "i;h different
batd",s of organisms. The batches were collected on Oclober 1 (Station :!-3 tests)
and October 26 (Station 1 tests).
o The reference toxicant ff'sts for the 2: sets of E6haustaurius tes.ts were not
cooduded concu-rrentIy ~i'th sediment tests. 1be reference toxkant tests were
conducted on November 1 for sedimenl tests initiated on October Z5 (Stations 2-3),
and on November 1 and November 8 fO(' sediment tests initiated on October 30
(Station 1).
o A fine-grained sediment control ("ith 5 replicates) was not included in the
Eooauslaudus test conducted ",,;:th Station 1 sediments..
o A fine-grained sediment control (with 5 replicate.) was not included in the
Rhepoxynius :esls.
Although your loxicity data have some value in assessing toyjcity at near-discharge
locations (Stations :!-3). 1M data cannot be used for between-station comparisons,
whlch was a mai« goel 0( the toxicity sur:ey. For examFle ... your Eo'haustaunus
results indicate substantial "Ioxkity' (100~ mortality) at Station L However,
devia600s from protocol o.nd study design make it impossible to determine the
cooID"bulioru 0( faclors other than Io><k ponutants [e.g., prolonged holding times,
gra3n-£ze effect< ... oc weakened orga1".lsms) on the observed response. The resuJts for
Station I are particularly important, as this location is designaled as the San
Francisco Bay reference site Cor an 1 Scw.lth Bay dischargers.
In addition. the r~ponses of F.ol'laustaurius to fine-grained reference sediment
differed in tes.ts (OndUClfd by the tW() 10xicity testing laboratories invDtved in thls
study (E V 5_ and roxscan). Since the labs used the same reference .. dimen~
differences in holdlng times or other sediment handling procedures could .have
