California Regional Water Quality Control Board. Central Valley Region 3614 East Ashlan Avenue Fresno, California 93726 RE: Annual and Fourth Quarter 2002 NPDES Monitoring Report Revised Monitoring and Reporting Program No. R5-2002-0085 Equillon Enterprises, LLC, dba Shell Oil Products US, Groundwater Cleanup System Shell Bakersfield Refinery, Bakersfield, California Dear Mr. Ramsey-Lewis: Shell Oil Products US (Shell), is submitting the Annual and Fourth Quarter 2002 NPDES Monitoring Report as required under the Monitoring and Reporting Program No. R5-2002-0085 established for monitoring treated discharge water from the groundwater remediation systems in use at the Shell Bakersfield Refinery in Bakersfield, California. Shell is also requesting an alteration to reporting schedule as established in the Revised Monitoring and Reporting Program No. R5-2002-0085. On page 5, paragraph 1 under the Reporting section of the document, it states that, "Daily, weekly, bi-weekly, monthly and quarterly monitoring results shall be submitted to the Regional Board within 45 days following the end of each calendar quarter. Annual monitoring results shall be submitted by 1 February of each year." In order to effectively utilize time and resources, Shell's intent is to submit the annual and fourth quarter monitoring results under the cover of a single document each year. Therefore, Shell requests that the schedule for submitting the annual results be modified to correspond to the submittal dates for the quarterly monitoring results. In addition, Shell is requesting a reduction in the sampling frequency for analyzing the effluent from each system for total petroleum hydrocarbons - gasoline range organics (USEPA Method 8015M), and methane, and ethane (USEPA Method 8015B) from bi-weekly to monthly. The second footnote on page 2 of the revised permit under "Effluent Monitoring" provides an allowance for reducing the frequency from bi-weekly to monthly if three consecutive bi-weekly sampling events result in non-detectable concentrations, at appropriate detection limits. Tables 3a and 4a from the Annual and Fourth Quarter 2002 NPDES Monitoring Report provide documentation for this reduction in the sampling frequency. We appreciate your assistance with this project.

Board, Central Valley Region (RWQCB), Waste Discharge Requirements for Equilon Enterprises, LLC DBA Shell Oil Products US Groundwater Cleanup System, Kern County, Order No. R5-2002-0085, dated June 5, 2002, and revised December 6, 2002, Shell Bakersfield Refinery is submitting this letter report summarizing the 2002 annual NPDES activities and monitoring results for the methyl tertiary butyl ether (MTBE) Intedm Remedial Measures (IRM) groundwater remediation project at the Shell Bakersfield Refinery and Shell Bakersfield Terminal, located in Bakersfield, California. This annual report also includes the fourth quarter (October through December)'2002 monitoring results required for submittal to the RWQCB by February 15, 2003 in accordance with the revised NPDES permit conditions. 1.0 BACKGROUND INFORMATION Dudng the mid to late 1990s, both the Shell Bakersfield Refinery and the Shell Bakersfield Terminal had releases of MTBE and other petroleum hydrocarbons to groundwater. Shell Oil Products US (Shell) began operation of soil vapor extraction and product skimming remediation systems at the Shell Bakersfield Terminal, and constructed two intedm groundwater extraction and treatment systems that began operation in August and October 2001, respectively. The locations of the intedm groundwater extraction and treatment systems, designated as IRM-1 and IRM-2, are shown on Figure 1. A detailed evaluation of the groundwater cleanup progress, trends, groundwater analytical results, and plume containment are presented in the quarterly groundwater reports submitted to the RWQCB. The next report, Annual and Fourth Quarter 2002 Groundwater Monitoring Report, Shell Oil Products US, Bakersfield, California, will be submitted to the RWQCB on or before February 15, 2003. The IRM-1 treatment system consists of groundwater extraction wells positioned at the leading edge of the plume, a granular activated carbon (GAC) treatment system, and associated piping and appurtenances. IRM-1 began operation on August 27, 2001. The system typically discharges to the Calloway Canal; however, between September 24 and November 11, 2002 the discharge water was diverted from the canal to the stormwater management pond at the refinery, at the request of the North Kern County Water District in order for the Water District to cut weeds growing in the canal bottom. The RWQCB was notified of this change in correspondence dated September 24 and H:~Projects~SH ELL~Bakersfield~cinaR077-O28~Repon'0 l'~,amsey-l.ewis04.doc Mr. Jarred Ramsey-Lewis January 20, 2003 Page 2 November 19, 2002. Extraction wells included in the IRM-1 treatment system are wells EW-3, EW-4, EW-5, EW-6, EW-7, EW-12, and EW-13 (Figure, 1). Wells EW-5, EW-6, and EW-7 were added to the system in November 2001. Two additional wells, EW-12 and EW-13 were added on November 19, 2002. The IRM-2 treatment system consists of extraction wells positioned near the center of the plume along Chadty Avenue, a GAC treatment 'system, and associated piping and appurtenances. IRM-2 began operation on October 3, 2001. This system also typically discharges to the Calloway Canal; however, between September 24 and November 11, 2002 the discharge water was diverted from the canal to the stormwater management pond at the refinery to allow weeds growing in the bottom of the canal to be cut by the Water District. The RWQCB was notified of this change in correspondence dated September 24 and November 19, 2002. Extraction wells included in the IRM-2 treatment system are wells B-149, EW-8, EW-9, EW-10, and EW-11 (Figure 1). Wells EW-8 through EW-11 were added to the IRM-2 system in December 2001. The IRM systems are operated and maintained per protocols established in the most recent Operations and Maintenance (O&M) Manual for the IRM systems, revised on June 4, 2002. The emergency procedures for the IRM systems are maintained in the O&M manual for the IRM systems. The O&M manual reflects the current construction and operation of these systems. Routine and emergency contacts for the IRM systems are provided below: John MacDonald - IRM Technician, TriHydro Corporation (661) 325-0784 phone (661) 809-0199 cell Linda Barnes, R.G., C.H.G. - Project Manager, TriHydro Corporation (307) 745-7474 phone (714) 356-9172 cell Steve Overman, P.E. - Environmental Supervisor, Shell Oil Products US (661) 326-4351 phone (661) 398-7801 pager 2.0 INFLUENT AND EFFLUENT MONITORING PROGRAM On October 16, 2001 Shell submitted a site-specific NPDES permit, Report of Waste Discharge for the NPDES Permit Application for the Shell Bakersfield Refinery, a Division of Shell Oil Products, to the RWQCB. During the interim, discharges from IRM-1 and IRM-2 were covered under two separate orders from the RWQCB. The operation and discharge from IRM-1 was permitted under the General Order 5-00-119, and the operation and discharge from IRM-2 was permitted under Order 91-250. On June 5, 2002, Shell received an official permit, Order No. R5-2002-0085 as adopted by the California RWQCB, governing the operation and discharge of both IRM-1 and IRM-2. Shell requested a clarification regarding the reporting frequency required under the Monitoring and Reporting Program No. R5-2002-0085 in correspondence dated September' 24, 2002. In response, the RWQCB modified the monthly and quarterly reporting schedule and issued a Revised Monitoring and Reporting Program No. R5-2002-0085 dated December 6, 2002. Influent samples from each system are required on a monthly basis and effluent samples for both systems are required on a bi-weekly basis. Effluent samples were required weekly during the first four weeks after initiation of discharge and bi-weekly after that. According to the Revised Monitoring and Reporting Program No. R5-2002-0085 (December 2002), sampling frequency for the following analytes may be changed from monthly to quarterly if the oxygenates: methyl tertiary butyl ether H:~,Projects~SHELL~akersfieicN=inal~077-028~Report01 ~amsey-Lewis04.doc Mr. Jarrod Ramsey-Lewis January 20, 2003 Page 3 (MTBE), methanol, ethanol, tertiary butyl alcohol (TBA), di-isopropyl ether (DIPE), ethyl tertiary butyl ether (ETBE), and tertiary amyl methyl ether (TAME) are not detected (at appropriate detection limits) in the influent for three consecutive months and/or the oxygenates and total petroleum hydrocarbons (TPH), benzene, toluene, ethylbenzene, and total xylenes (BTEX) are not detected (at appropriate detection limits) in the effluent samples for three consecutive months. The sampling frequency for oxygenates may be a. djusted to annually if the oxygenates are not detected in the influent samples for three consecutive quarters. Sampling frequency will revert back to the original schedule outlined within the permit if any of the above constituents are detected at appropriate detection limits in the influent or the effluent samples. ' Influent samples are collected from each of the extraction wells and then an aggregate sample is collected before the groundwater enters the treatment system. The samples are representative of the nature of the influent. Effluent samples are collected just before the processed water is discharged into the outfall, and are representative of the nature of the effluent discharge. Sampling ports were installed in the extraction well, influent, and effluent lines of the IRM treatment systems. Ports were also installed within and between the GAC units. Table 1 summarizes the location and purpose for each sample port. The following protocols were used to collect influent and effluent samples: Label sample bottles with proper sample identification; Locate the appropriate sampling port; Open sample spigot and discharge water for approximately 30 seconds; Position the sample container beneath the sample spigot and collect the water sample from a uniform, laminar (Iow-flow) stream; ensure that sample containers are completely filled and that no air bubbles are present in volatile organic compound (VOC) sample vials; Enclose the sample jars in bubble wrap inside a ziplock bag. Place the bag in a opaque cooler filled with ice; Proceed to the next sampling port and repeat the procedures described above; Seal the cooler, complete the laboratory Chain-of-Custody form and overnight shipping label; and Deliver the sample cooler to the analytical laboratory via overnight courier. 3.0 IRM SYSTEMS MONITORING RESULTS Analytical results for each of the remediation systems are summarized below. 3.1 IRM-1 Results As required by revised Order No. R5-2002-0085, influent and effluent samples collected from IRM-1 are analyzed for the following parameters: Total petroleum hydrocarbons - gasoline range organics (TPH - GRO); Benzene, Toluene, Ethylbenzene, and Xylene (BTEX); Ethanol and Methanol; Methyl tertiary butyl ether (MTBE); H:~Projects~SHELL~Bakersfield~Final~077-O28~.eportO l~Ramsey-l, ewis04.doc Mr. Jarrod Ramsey-Lewis January 20, 2003 Page 4 Tertiary butyl alcohol (TBA); Di-isopropyl ether (DIPE); Ethyl tertiary butyl ether (ETBE); Tertiary amyl methyl ether (TAME); and Total dissolved solids (TDS). Samples collected from extraction wells EW-3 through EW-7, EW-12, and EW-13 are analyzed for the same parameters listed abov, e with the exception of TDS. Influent and effluent water is monitored for general water quality parameters including pH, specific conductivity, temperature, and dissolved oxygen. Shell routinely calibrates the inline dissolved oxygen meter and the water quality meters at each of the IRM systems. Calibration is completed weekly during system monitoring and maintenance. The calibration procedures follow the guidelines established by the manufacturers of each meter. Total flow through IRM-1 is recorded daily. Table 2 presents the'monthly flow statistics for the IRM-1 system for 2002. The maximum daily flow allotted for the IRM-1 system under the permit is 500,000 gallons. The highest daily maximum flow measured in 2002 was 336,960 gallons recorded on June 26, 2002. During the fourth quarter of 2002, the total monthly flow from IRM-1 was approximately 5,016,380 gallons for October, 5,353,410 gallons for November, and 5,942,920 gallons for December. It should be noted that EW-4 was shut down from August 23 through November 26, 2002. The water level' within this well was depressed and the pump intake was above the static water table. In addition, the pump was damaged and required maintenance; On November 26, the pump was replaced and lowered approximately 5 feet then restarted. Analytical results for 2002 for IRM-1 are summarized in Tables 3a, 3b, and 3c. Organic data are summarized in Table 3a. Inorganic and field measurement data are summarized in Table 3b. A statistical evaluation of the data is provided on Table 3c. The monitoring of total lead has been discontinued based on the infiuent and effluent monitoring criteria detailed in Order No. R5-2002- 0085, that states, "if lead is not detected in the first two sampling events then testing may be discontinued thereafter". Specific conductance and pH in the influent and effluent samples have remained relatively stable throughout 2002. Laboratory analytical reports for the fourth quarter are included in Attachment A of this report. Analytical reports for the previous three quarters are available in the quarterly reports submitted to the RWQCB in June, July, and October 2002. 3.1.1 Extraction Well Results MTBE was detected at least once in the samples collected from each of the extraction wells (EW-3 through EW-7, EW-12, and EW-13) during 2002. Concentrations in the extraction well samples ranged from non-detectable at 1 microgram per liter (l~g/L) to 4,100 I~g/L (EW-5, 4/23/02). TPH-GRO was detected in the groundwater samples collected from EW-3, EW-4, and EW-5 ranging from non- detectable at 100 I~g/L up to 1,900 pg/L (EW-5, 4/2/02). BTEX constituents were not measured above the laboratory detection limits in any of the samples. Of the additional oxygenates, ethanol and TBA were sporadically detected in wells EW-3, EW-5, EW-6, and EW-7. Several of the detections were J flagged as estimated below the practical quantitation limits (PQLs). A J flag indicates that the data is an estimated value by the laboratory. J flags of the IRM systems analytical data are used to indicate that the sample results cannot be positively identified above the laboratory detection limits .or PQLs. H:~Projects~HELL'tBakersfield~Final~077-O28~Report0 l~amsey-Lewls04.doc Mr. Jarrod Ramsey-Lewis January 20, 2003 Page 5 Dudng the fourth quarter of 2002, MTBE was detected in EW-5, EW-6, EW-12, and EW-13. MTBE concentrations in the extraction well samples ranged from non-detectable at 1 I~g/L to 940 I~g/L (EW- 5, 10/9/02). TPH-GRO was only detected in one extraction well during the fourth quarter 2002 (EW-5; maximum concentration of 370 I~g/L on 10/9/02). BTEX constituents were not measured above the laboratory detection limits in any of the samples during the fourth quarter. Of the additional oxygenates, ethanol was detected above the PQL in EW-6 on October 22 (220 lzg/L) and TBA was detected in EW-5 dudng the October 9 sampling event (59 izg/L). There were no other detections above the PQLs. . 3.1.2 Influent Results In 2002, MTBE was detected in the IRM-1 influent samples collected from SP-1, SP-2, and SP-3. During the year, MTBE concentrations in the influent samples ranged from 2,900 p.g/L measured from the pretreated water in the first GAC vessel (SP-1, 6/12/02) down to non-detectable at 1 I~glL consistently measured in the pretreated water in the final GAC unit (SP-3). TPH-GRO was only detected in the infiuent samples collected from SP-1 with concentrations ranging from multiple non- detections at 100 i~g/L to 1,100 I~g/L (7/13/02). Benzene was detected in SP-1 and SP-2 on December 2 (8.9 p.g/L) and July 24 (0.95 p.g/L), respectively. Ethanol and TBA were periodically detected in the influent samples collected from SP-1, SP-2, and SP-3. During the fourth quarter 2002, MTBE, TPH-GRO, benzene, and TBA were measured above the PQLs in samples collected from SP-1. MTBE results in SP-1 ranged from 1,100 izg/L (11/4/02)to 360 I~g/L (12/2/02). TPH-GRO concentrations were reported as 230 tzg/L in October, 210 I~g/L in November, and 110 i~g/L in December. Benzene was detected in the December 2 sample (8.9 I~g/L) and TBA was identified in the December 16 sample (120 Izg/L). Constituents were not reported above the laboratory detection limits in samples collected from SP-2 or SP-3 during the fourth quarter. 3.1.3 Effluent Results None of the analytical constituents were detected above the laboratory detection limits in the effluent samples collected and analyzed from IRM-1 dudng 2002. Effluent limitations were not exceeded for any of the constituents or field parameters dudng 2002. Figure 2 presents MTBE concentrations measured in each of the influent and effluent samples collected in 2002 from the IRM-1 system. As shown, although influent MTBE concentrations vaded during the year, effluent concentrations were consistently non-detect. Effluent samples were collected and analyzed for TPH-GRO (EPA Method 8015M), as well as, methanol and ethanol (EPA Modified 8015B) bi-weekly trough May and monthly from to December 2002. Order No. R5-2002-0085, specifies these constituents are required biweekly. However, the second footnote on page 2 of the revised permit under "Effluent Monitoring" provides an allowance for reducing the frequency from bi-weekly to monthly if three consecutive bi-weekly sampling events result in non-detectable concentrations, at appropriate detection limits, which is documented in Table 3a. Justification for the reduction in sampling frequency is provided herein as per paragraph 4 under "Reporting", page 5 of the revised permit No. R5-2002-0085. Acute bioassay testing of the effluent samples collected from IRM-1 is conducted quarterly per permit requirements. Acute bioassay analysis is conducted according to specification in the U.S. Environmental Protection Agency (USEPA) document EPN600/4-90/O27F and amendments made to the document. Bioassay samples consist of 24-hour composites collected from the last discharge point before entedng the raceiving water and are representative of the quality of the discharge. H:~Projects~SHELL~Bakersfietd~FinaR077-O28~Report01 ~,amsey-LewisO4.doc Mr. Jarmd Ramsey-Lewis January 20,2003 Page 6 Because the Calloway Canal is an ephemeral stream, no dilution is required. Test species for the bioassay test are fathead minnows (Pimephales promelas). Bioassay samples were collected and tested in March, June, September, and December 2002. Bioassay analysis conducted for each quarter of 2002 had a survival rate of 100%. Bioassay results for IRM-1 are included on Table 3b. 3.2 IRM-2 Results The influent, effluent, and extraction well samples collected from IRM-2 are analyzed for the same analytical list as those presented in Section 3.1 for the IRM-1 system. Influent and effluent water is also monitored for general water quality parameters including pH, specific conductivity, temperature, and dissolved oxygen. Total flow through IRM-2 is recorded daily. Table 2 presents the 'monthly flow statistics for the IRM-2 system for 2002. The highest daily maximum flow measured in 2002 was 307,728 gallons recorded on May 15, 2002. It should be noted that extraction well EW-8 was taken offline between February 19 and March 22, 2002 due to pump failure, which accounts for the decline in maximum daily flow in March 2002. Dudng the fourth quarter of 2002, the total monthly'flow from IRM-2 was approximately 5,146,560 gallons for October, 5,021,330 gallons for November, and 5,067,100 gallons for December. Analytical results for 2002 for IRM-2 are summarized in Tables 4a, 4b, and 4c. Organic data are summarized in Table 4a. Inorganic and field measurement data are summarized in Table 4b. A statistical evaluation of the data is provided on Table 4c. The monitoring 'of total lead has been discontinued based on the influent and effluent monitoring criteda detailed in Order No. R5-2002- 0085, that states, "if lead is not detected in the first two sampling events then testing may be discontinued thereafter". Specific conductance and pH in the influent and effluent samples have remained relatively stable throughout 2002. Laboratory analytical reports for the fourth quarter are included in Attachment A of this report. Analytical reports for the previous three quarters are available in the quarterly reports submitted to the RWQCB in June, July, and October 2002. 3.2.1 Extraction Well Results MTBE was detected at least once in the Samples collected from each of the extraction wells (EW-8 through EW-11, and B-149) during 2002. Concentrations in the extraction well samples ranged from non-detectable at 1 I~g/L to 59,000 I~g/L (EW-8, 1/1/02). TPH-GRO was detected in the groundwater samples collected from EW-8, EW-10, and B-149 ranging from non-detectable at 100 izg/L up to 22,000 i~g/L (EW-8, 7/2/02). BTEX constituents were not measured above the laboratory detection limits, with the exception of the July 2 sample collected from well B-149 (ethylbenzene measuring 0.61 ~g/L). Of the additional oxygenates, ethanol and TBA were sporadically detected in each of the extraction wells, as well as, ETBE and TAME concentrations in EW-8. Many of the detections of these oxygenates were J flagged as estimated below the PQL. Dudng the fourth quarter of 2002, MTBE was detected in each of the extraction wells. MTBE concentrations ranged from non-detectable at 1 I~g/L to 25,000 i~g/L (EW-8, 10/22/02). TPH-GRO was detected in well EW-8 in October (15,000 lzg/L) and November (2,600 lzg/L. TPH-GRO was also detected in well B-149 in October (290 i~g/L). BTEX constituents were not measured above the laboratory detection limits in any of the samples during the fourth quarter. Of the additional H:~Projects~SHELL~Bakemfleld~FinaR077-028\Report0 l~Ramsey-Lewis04.doc Mr. Ja~od Ramsey-Lewis January 20,2003 Page 7 oxygenates, ethanol was detected in EW-8 (110 p.g/L) in the October 9, 2002 sample. TBA was also detected in EW-8 (650 ~.g/L) and B-149 (71 p.g/L) in the same sample. There were no other detections above the PQLs. 3.2.2 Influent Results In 2002, MTBE was detected in, the IRM-2 influent samples collected from SP-5, SP-6, and SP-7. MTBE concentrations in the influent samples ranged from 7,400 I~g/L measured from the pretreated water in the first GAC vessel (SP-5) down to non-detectable at I I~g/L measured, in the pretreated water in the final GAC unit (SP-6). TPH-GRO was detected in samples collected from each of the GAC vessels in 2002, with concentrations ranging from non-detectable at 100 Fg/L to 4,000 p.g/L (SP- 1, 1/29/02). BTEX constituents were not measured above the laboratory detection limits in any of the samples dudng 2002. TBA was periodically detected in the influent samples collected from SP-1, SP- 2, and SP-3. There were no other detections above the PQLs. Dudng the fourth quarter 2002, MTBE, TPH-GRO, and TBA were measured above the PQLs in samples collected from SP-5. MTBE results in SP-5 ranged from 560 I~g/L (11/25/02) to 1,100 p.g/L (10/28/02). TPH-GRO concentrations were reported as 270 I~g/L in October, 360 pg/L in November, and 270 Fg/L in December. TBA was identified in the October 28 sample (130 p.g/L). Constituents were not reported above the laboratory detection limits in samples collected from SP-6 or SP-7 during the fourth quarter. 3.2.3 Effluent Results TBA was detected in the effluent samples collected on March 18 (18 I~g/L), March 28 (20 pg/L), and April 1, 2002 (11 pg/L). In March and April 2002, discharges for IRM-2 were covered under Order No. Order 91-250. This Order did not establish maximum limitations for TBA in the effluent water from IRM-2. Ethanol was detected in the effluent sample collected on August 13th (120 i~g/L). Ethanol was not detected in the effluent samples during subsequent monitoring events. There were no other detections reported above the PQLs in the effluent samples collected from IRM-2. Figure 3 presents MTBE concentrations measured 'in each of the influent and effluent samples collected in 2002 from the IRM-2 system. As shown, although influent MTBE concentrations varied during the year, effluent concentrations were consistently non-detect. Effluent samples were collected and analyzed for TPH-GRO (EPA Method 8015M), as Well as, methanol and ethanol (EPA Modified 8015B) biweekly through May and monthly from June to December 2002. Order No. R5-2002-0085, specifies these constituents are required biweekly. However, the second footnote on page 2 of the revised permit under "Effluent Monitoring" provides an allowance for reducing the frequency from bi-weekly to monthly if three consecutive bi-weekly sampling events result in non-detectable concentrations, at appropriate detection limits, which is documented in Table 4a. Justification for the reduction in sampling frequency is provided herein as per paragraph 4 under "Reporting", page 5 of the revised permit No. R5-2002-0085. Acute' bioassay testing of the effluent samples collected from IRM-2 is conducted quarterly per permit requirements. Acute bioassay analysis is conducted according to specification in the U.S. Environmental Protection Agency (USEPA) document EPN600/4-90/O27F and amendments made to the document. Bioassay samples consist of 24-hour composites collected from the last discharge point before entedng the receiving water and are representative of the quality of the discharge. Because the Calloway Canal is an ephemeral stream, no dilution is required. Test species for the bioassay test are fathead minnows (Pimephales promelas). Bioassay samples were collected in H:~Projects~SH ELL~Ba kemfield~Final~077 -O28~Repor tO 1 ~,a msey-Lewts04.doc Mr. Jarrod Ramsey-Lewis January 20, 2003 Page 8 June, September, and December 2002. Bioassay results for June had a survival rate of 95%; survival rates for September and December were 100%. The minimum survival rate for any one bioassay, as established in the Waste Discharge Requirements for Order No. R5-2002-0085 is 70%. The median for any three or more consecutive bioassays is 90%. Acute bioassay testing was not conducted in the first quarter on the IRM-2 effluent. Discharges from IRM-2 were permitted under Order No. 91-250. This Order did not establish requirements for acute bioassay testing of the effluent water from IRM-2. Acute bioassay testing of the effluent samples collected from IRM-2 is currently conducted quarterly as required under the revised Order No. R5-2002-0085. Bioassay results for IRM-2 are included on Table 4b. 4.0 RECEIVING WATER, canal, AND STORMWATER POND MONITORING PROGRAM As required by revised Order No. R5-2002-0085, receiving waters from an upstream (R-l) and a downstream (R-2) station should be monitored monthly whenever possible for the following parameters: estimated flow, dissolved oxygen, pH, temperature, electrical conductivity, and turbidity. Receiving waters should be collected and analyzed from eaCh station and analyzed for TDS once each quarter. Water conditions within the Calloway Canal are inspected weekly. Field notes are recorded documenting the presence or absence of: · Floating or suspended matter; · Discoloration; · Bottom deposits; · Aquatic life; · Visible films, sheers, or coatings; · Fungi, slimes, or objectionable growths; and · Potential nuisance conditions. Receiving water samples were collected on January 3 and January 8, 2002. The receiving water stations within the canal remained dry the remainder of the year. Analytical results from the January 2002 receiving water samples are summarized on Table 5. Trace levels of MTBE and TDS were detected in samples collected from R-1. The concentrations were all below the NPDES permit discharge limitations (Table 5). As previously discussed, discharge water from IRM-1 and IRM-2 was diverted to the stormwater management pond at the refinery between September 24, 2002 and November 11, 2002. Order No. R5-2002-0085 requires that a minimum freeboard of two feet shall be maintained in the onsite stormwater management pond. Field documentation recorded during the fourth quarter is included as Appendix B and indicates that two feet of freeboard was maintained in the stormwater management pond during the time the discharge was diverted. Field documentation for the previous three quarters were included in the quarterly reports submitted to the RWQCB in June, July, and October 2002.

In addition to routine sampling and monitoring, Shell will submit and analyze samples from the IRM systems for priority pollutants in March and October 2003. Samples will be analyzed for pH, hardness, volatile organic constituents, semi-volatile organic constituents, inorganic constituents, pesticides, and polychlorinated biphenyls. Sample results will conform to the standards established in the Policy for Implementation of Toxics Standards for Inland Sur[aoe Waters, Bays, and Estuaries of Califomia. As required by permit, Shell also proposes collecting and testing effluent samples for dioxin during 2003. Samples will be collected once during dry weather and once during wet weather. Analysis and reporting will conform to the guidelines established in the Policy for Implementation of Toxics Standards for Inland Sur[aoe Waters, Bays, and Estuaries of California. The next quarterly report will be submitted to the Regional Water Quality Control Board on or before May 15, 2003. Questions and comments regarding this quarterly report should be directed to Mr. Steve Overman (Shell Oil Products US) at 661-326-4351 or to Linda Barnes(TriHydro Corporation) at 307-745-7474.
