Average monthly effluent limit means: the highest.allowable average ofd~ily discharges over a calendar month. To calculate the di~charge Value to compare to the limit, you add the value of each.daily discharge measured during a calendar month and divide this sum by the total. number of daily discharges measured.

b Maximum daily effluent limit *1s the highest allowable daily discharge. The daily' discharge is the aver:age discharge of a pollutant measured during a calendar day. This does not apply to pH or temperature.

1f multiple excursions occur during th~ qay, note the dur~~on fo.r each excursion. If submitting electronic DMRs, include this additional information in the oaraineter notes.

4 Temperature grab sampling rnust occur when the effluent is at or near its daily maximum temperature, which usually oc6urs in the late 'afternoon: If measuring temperature continuously, the Permittee must determine and repc)rt a dally maximum frorn half-hourmeasurernents. in a 24-hour period. Continuous monitoring instri.rrnents must achieve an accuracy of 0.2 degrees C and the Permittee must verify accuracy annually.

The sai:npling*point for temperafure is :at the Circulating Water Pumphouse (CWP) uritil monitoring equipment is oper~tional in the River Pumphouse (RP). The Permittee may maintain temperature monitoring equipment at the CWP for use during maintenance and outages of equipmentat the RP. The Permittee must inform EFSEC on the* monthly report When the RP Is ooerational, and thereafter when reported results contain data from the CWP.

6 Monthlv*means once everv calendar month.

7 Grab means an lndi\\t'idual sample collected over a fifteen* (15) minute,.or less*, period.

8 A Grab sample may be-substituted for 24-Hou.r composite sampling until equipment installed as required in Section S?.8 is operational. The Permittee must inform EFSEC on the monthly report. of the sample type.

9 If the Permittee submits engineering qalculations which demonstrate tllat the regulated pollutants are not detectable in the final discharge by the analytical methods in 40 CFR part

136, annual monitoring is not required. The Permittee must, at a minim.um, sample once in the last year to meet permit renewal application requirements. See Appendix A to identify the specific pollutants in the orioritv pollutant arouos listed.

1 o Asbe.stos grab sampling must occur once' during the Pemiit cycle when the circulating water cooling system is operating at an average number of cycles of concentration and only blowdown is being discharged. Test results must be submitted with the application for perinit renewal.

11 Volumes of batch releases of water for pond *draining m*ay be estimated.~asecl on level

measurements. Feed-ar:id-bleed discharges made directly to the blowdown line must be measured bv flow meter.

12 Prior to comm~ncement of discharges,the Permit!ee must.verify that pHJ$ within specified fimits. Measurements must be taken dailv Whlle,.dischan:ie is in oroaress.

13 Samples must reeres~nt a typical facility dls~harge. to Outfall 002. Th~ Permittee must collect one sample annually between March 15 - May 15 and one sample annually between Seotember 15 - November 15.

The Pennittee must consider the analysis required above dUring preparation of the engineering report or facilities plan and plans and specifications and rnust includethese.to the extent*practical, In cases where the Pennittee detennines the probable need to bypass early, the.Permittee*must continue to analyze. conditions.up to and includfug the construction period in an effort.to minimize or eliminate the bypai;s.

c. EFSEC will *consider the following prior to issuing an administrative order for this type ofbypass:

Page 19 of48 PermitNo. WA002515-l

If the bypass is necessary to perform construction or

maintenance~related activities essential to meet the requirements of this permit.

If fea8ible alternatives to bypass exist, such as. the use of auxillary treatment facilities, retention of untreated wastes, stopping production, maintenance during.normal periods of equipment down 'time, or transport of untreated wastes to anothertreatment facility. *

conditions at the boundary of the acute mixing zone, defined in Section S 1.B of this permit. The ACEC equals 11 % effluent.

S13.B. Compliance with the effiuent limit for acute toxicity

-Compliance with the effluent limit for acute toxicity means the results of the testing specified in Se.ction C show no statistically significant difference in survival between the control and the ACEC.

If the test results show a statistically significant difference in surVival between the control and. the. ACEC, and EFSEC has not determined the test result to be anomalous UPder Section D, and the test is otherwi.se-v~lid, the result is a violation of the effluent limit fQr acute toxicity. The Permittee must immediately conduct the additional testing described in Section D..

The Peimittee must determine the-statistical significance by conducting a hypothesis test at *the 0.05 level of significance (Appendix H, EPA/600/4-89/001 ).

If the difference in survival between the control and the ACEC is less than 10%,

th~ Permittee must conduct the hypothesis test-at the 0.01 level *of si_gni:ficance.

Sl3.C. Compliance testing for acute toxicity The Permittee must:

L Perform the acute toxicity tests with 100% effluent, the ACEC, and-a control, or with a full dilution series.

Response to noncompliance with the effluent limit' for acute toxicity If a toxicity test conducted tinder Section C detei'niines a statistically significant difference in response between the ACEC and the control, using the statistical test described in Section B, the Permi:ttee mµst b~gin additional testing within one week from the time o{recelving the test results. The Pennittee must:

1. Conduct one additional test each week fot four conse~utive weeks, using the same test and species* as the failed compliance test.

2*. Test at least'fiveeffluent concentratfons and a control to determine appropriate point estimates. One of these effluent concentrations.must equal the ACEC~ The results of the test at the ACEC will detennine compliance with the effluent limit for acute toxicity as described in Section B.

3. Return to the :original monitoring.frequency in Section C after completion of the additional compliance nwnitorfng.

A.nomalous test results: *Ifa tQxicity test conducted under Section C indicates nonct>mpliance with the acute toxicity limit and the Pennitte.e believes that the.

test result is anomalous, the Permittee may *notify EFSEC that the compliance test result may be anomalous. The Permittee may take one additional sample for toxicity testing and wait for notificatiQn from EFSEC l?efQre completjng the addi~jonal testjng. '.lbe Pennittee must submit the notitic.ation with. the report of

the compliance. test resµlt and. identify the reasQn for com;idering the compliance test result to be anomalous.

If EFSEC determines that the test resultwas not anomalous, the Pennittee must comi;>lete all of the additional monitoring required in this section.. br, If the one additional s~mple fails to comply with the effluent limit for.acute.

toxicity,. then the Pennittee must complete all of the additional monitoring required in this section.. Or, If EFSEC determines that the test result was anomalous, the.one additional test

result will replace the anomalous test result.

Jfall of the additiOnal testing in *s 13.D,1 and 2 complies with the permit limit, the Pennittee must submit a report to EFSEC on possible causes and preventive measures for the transienttoxicity event, which triggered the.additional complianc*e monitoring.

.G15. Upset Definition -- "Upset" me.ans an exceptional incident in which there is unintentional and temporary noncompliance with technology-based permit effluent limits because of factors beyond the reasonable control of the Perm:ittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment

fa9ilities, inadeq~te treaQ:nent facilities, lack of preventive maintenance, or careless or improper operation.

An.upset constitutes an affirmative defense to an action brought for noncompliance with such technology-based permit eftluent limits if the. requirements of the following

paragraph are met.

A Permittee who wishes to establish the affirmative defe1;1se of upset must demon&trate,

~hrQugh propedy signed, contempi:>raneous operating logs, or other relevant evidence that:

1. An upset occurred and that the Pennittee can.identify the cause(s).ofthe upset.

2. The.Permitted facility was.being properly operated at the time of the upset.

3. The Permittee submitted notice of the upset as n:;quired in SpedalCondition 83.E.

G20. Reporting re.quirements applicable to existing manufacturing, commerci~I, m'lning,. and,silvic1.1ltural dischargers The Permittee belonging to the categories of existing manufacturing,* commercial, mining, or silviculture must'notify' EFSEC as soon as they know or have reason to believe:

1. That any activity has occurred or will occur which would result in the discharge~ on a routh;ie or frequent basis~ of any toxic pollµtant which is riot limited in this pertriit, if that discharge wili exceed the highest of the following "notification levels:"

a. One hundred microwams per liter (lOO*µg/L).

'b. Two htindred mforograms ]Jet liter (200 µg/L) for acrolein and acrylonitrile; five hunch:ed micrograms per liter (500 µg/L) for 2,4"'.dinitrophenol and for 2... methyl..

4,6-dinitrophenol; and one: milligram per liter(l mg/L) for antimo11y:

c. Five (5) times the maximum concentration value reported for' that pollutant in the pemiit application in:accordancewith 40 CFR 1222l(g)(7).

d. The level established by the Director in accordance with 40 CFR 122A4(f).

. 2. That any activity has occurred or will occur which would result in any discharge, on a non-routine or infrequent basis, of a toxic pollutant which is not limited in this permit, if that discharge will exceed the highest of the following "notification levels:

a. Five hundred micrograms per liter (500).lg/L).

b. One milligram per liter (1 mg/L) for antimony.

c.- Ten (10) times the maximum concentration value reported for that pollutant ~n the*

permit application in accordance' with 40 CFR 122'.2l(g)(7).

d. The level established by the Directodn accordance with40 CFR 122.44(f).

G21. Compliance schedules Page 39 of48 PermitNo. WA002515-1 Reports of compliance or noncompliance with, or any progress.reports on, interim and final requirements contained in any compliance schedule of this permit must be submitted no later than fourteen (14) days following each schedule date.

Page40 of48 Permit No. WA002515-1 Appendix,A LIST OF POLLUTANTS WITHANALYTICAL METHODS, DETECTION LIMITS AND QUANT/TAT/ON LEVELS The Penriittee must usi;: the specified*analytical methods, detection limits*(DLs) and quantitation levels(QLs) in the following table for permit :and application required monitoring unless:

Another permit condition specifies other methods, detection levels, or quantitation levels.

The method used produces measurable results in the sample ~d.EPA has listed it as an EPA-approved.

method in-40CFRPart136.

If the Permittee uses an alternative method, not specified in. the permit and as allowed above,.it must report the test method, DL, and QL on the discharge monitoring report or in the required report.

If the Permittee* is unable to obtain the required DL and QL in.its effluent que to matrix effects, the Pennittee must submit a matrix-specific di;:tection lit.nit (MDL) and a quantitation limit. (QL) to EFSEC with appropriate laboratory do~cumentation.

When the permit requires the Permittee to measure the base neutral compounds in the list of priority pollutants, it mtist measure all of the base neutral pollutants listed in the table. below. The list includes EPA required base*

neutral priority pollutan~ and several additional polynuclear aromatic hydrocarbons (P AHs ). The Water Q:uality Program adCled several P AHs to the list ofbase neutrals below from Ecology's Persistent Bioaccumulative Toxics (Pa.T) List.. It only ad4ed those PBT* parameters of interest to Appendix A that did not increase the overall cos.t of analysis unreasonably.

EFSEC added this appendix to the permit fu order to reduce the number of analytical "non-detects;'* in pennit-required monitoring and to measure* effluent c0ncentrations near or below criteria values where possible at.a reas.onable cost.

2. Quantitation Level (QL) also known.as MinimumLevel ofQuantitation (ML)- the lowest level at which the entire analytical system must give a recognizable signal and acceptable calibration point for the analyte. It is equivalent to the concentration ofthe lowest calibration standard, assuming that the lab has used all method-specified sampie weights, volumes, and cleanup procedures. The QL is calculated by multiplying the MDL by 3.18 and rounding the result to the number nearest to (1, 2, or5) x ion, where n is an integer:- (64 FR 30417).

ALSO GIVEN AS:

The smallest detectable concentration of analyte greater than the Detection Limit {DL) where the accuracy (precision & bias) achieves the objectives of the intendeq purpose.
