Dear Mr. Sampey,

Thank you for your time on the phone yesterday. Ea stern Research Group, Inc. (ERG) under EPA Contract No. 68-C-02-095 is e-mailing you on EPA’s behalf to request clarification of 2008 di scharge monitoring reports for the Chevron Oronite - Oak Point Plant (LA0005738). Here is some background on what the information is used for

.

EPA reviews publicly-available DMR data to fulfill its review obligation under Section 304(b) of the C lean Water Act. The CWA requires EPA to annually review and, if appropriate, revise its water pollution control technology-based regulation s, called “effluent limitations guidelines” or "effluent guidelines,” that limit the discharge of pollutants to waters of the U.S. from various categ ories of industrial facilities. EPA is currently conducting its 2010 annual review of existing efflu ent guidelines and potential industrial guidelines which may need to be included (see http://www.epa.gov/guide/304m/ for further informat ion). EPA will discuss this review and the results in its 2010 Effluent Guidelines Program Plan scheduled for publication in the Federal Regis ter in December 2010. As part of the 2010 annual re view, EPA is evaluating the data in discharge monitoring reports from 2008 and needs fu rther information to complete the review.

We would like to obtain additional information on t he following quantity data for the following pollut ant discharges from your facility. Our records show the following quantities were discharg ed:

Dec 2008; Outfall 202:Hexachlorobenzene: 0.0544 kg/day

Benzo[a]pyrene: 0.0544 kg/day Chrysene: 0.0544 kg/day Benzo[k]fluoranthene: 0.0544 kg/day Benzo[b]fluoranthene: 0.0544 kg/day Benz[a]anthracene: 0.0544 kg/day

As we discussed on the phone, these pollutant disch arges were actually non-detect; however, you used 1 /2 the detection limit to calculate and report the load. Please confirm that these pollutan ts were actually measured below the detection limit

.

We appreciate your help in confirming the above dat a.

If you have any questions regarding this request, p lease call me at (703) 633-1673. If you would like to speak directly with EPA regarding this request, you can contact William F. Swietlik of EPA 's Office of Water/Engineering Analysis Division by phone at (202) 566-1129 or by email: swietlik.william@epa.gov.

Thanks,
Elizabeth

Value Description Pace Analytical Services, Inc. 1000 Riverbend Blvd. Suite F St. Rose, LA 70087 (504) 469-0333

A10 N-Nitrosodiphenylamine is reported as diphenylam ine. A11 This analyte is a common solvent. Its presence in field samples may be an artifact of sample colle ction, transport, laboratory storage or analysis. A25 This analyte is a common plasticizer. Its prese nce in field samples may be an artifact of sample c ollection, transport, laboratory storage or analysi s. A99 This analyte is a poor performer by this method. The QC recovery data for this analyte may be pooror erratic as demonstrated by a performancebased statistical evaluation. D1 The analysis was performed at a dilution due to t he high analyte concentration. Q1 The matrix spike recoveries are poor. Acceptable method performance for this analyte has been demon strated by the laboratory control sample

recovery. Q5 Insufficient sample was provided to perform matri x spike analyses on any sample in this analytical b atch. Method performance for this analyte has

been demonstrated by the laboratory control sample recovery. S1 The surrogate recovery was above the QC limit. T he data are reported without qualification since th e associated target analytes were not detected in

the sample. J This estimated value for the analyte is below the adjusted reporting limit but above the instrument r eporting limit. U The analyte was analyzed for but not detected at t he reporting limit or method detection limit indica ted. B This analyte was detected in the method blank. E The sample concentration is above the linear calib rated range of the analysis. ND The analyte was analyzed for but not detected at the reporting limit or method detection limit indic ated. MDL The adjusted method detection limit. LCS(D) Laboratory Control Sample (Duplicate). MS(D) Matrix Spike (Duplicate). DUP Sample Duplicate.
