The Phase I stormwater treatment system is divided into two separate systems (Phase I North and Phase I South) bisected by an easement for the Olympic pipeline. The project includes the construction of a 5-lane road with bike lanes, curbs, gutters, and sidewalks from SW 161h Street to SW 191h Street, a 3-lane road with curbs, gutters, and sidewalks from SW 19th Street to SW 27th Street, and two stormwater treatment systems at the Phase I and Phase II wetland mitigation locations. PURPOSE OF STUDY This water quality report has been prepared in accordance with conditions set forth in the approved Water Quality Certification for the City of Renton Phase I and I I Stormwater Treatment System. The Water Quality Certification is subject to the conditions provided in Order #1999-4- 01497, dated 6 August 2001. The purpose of this report is to provide a summary of results for stormwater and sediment quality monitoring performed on 20 May 2005. Sediment and water quality monitoring is conducted at designated locations on a biennial basis (during years 1, 3, and 5) at the City of Renton's Phase I and II stormwater treatment systems. During the 20 May 2005 monitoring event, Year 3 sampling was conducted at the Phase I South and Phase II stormwater treatment systems. In addition, the final sampling event (Year 5) was completed for the Phase I North stormwater treatment system. The final sampling event for the Phase I South and Phase II stormwater treatment systems will be conducted in 2007. A report on the sediment and water testing results will be prepared following the scheduled monitoring event and will be submitted to the City of Renton and Osborne Pacific for review prior to being submitted to the Department of Ecology. RESULTS AND CONCLUSIONS Stormwater sample analysis showed that water temperature, pH, turbidity, and total zinc values complied with State Surface Water Quality Standards (WAC 173-201A). Fecal coliform was measured well above State Surface Water Quality Standards in both the Phase I North and Phase II systems. Metals concentrations detected from downstream sediment samples of all three stormwater treatment systems were well below freshwater sediment quality guidelines. 7 August 2005 Talasaea Consultants, Inc. 674-WQCM3-2005.doc Page i City of Renton Phase I and II Stormwater Treatment Water Quality Monitoring Report TABLE OF CONTENTS i.

The Water Quality Certification is subject to the conditions provided in Order #1999-4- 01497, dated 6 August 2001. The purpose of this report is to provide a summary of results for stormwater and sediment quality monitoring performed on 20 May 2005. 1.1 Monitoring Schedule Sediment and water quality monitoring is conducted at designated locations on a biennial basis (during years 1, 3, and 5) at the City of Renton's Phase I and II stormwater treatment systems. During the 20 May 2005 monitoring event, Year 3 sampling was conducted at the Phase I South and Phase II stormwater treatment systems. In addition, the final sampling event (Year 5) was completed for the Phase I North stormwater treatment system. The final sampling event for the Phase I South and Phase II stormwater treatment systems will be conducted in 2007. A report on the sediment and water testing results will be prepared following the scheduled monitoring event and will be submitted to the City of Renton and Osborne Pacific for review prior to being submitted to the Department of Ecology. 2.0 SITE CHARACTERISTICS The Phase I North and South stormwater treatment system is located at the northeast corner of Oakesdale Avenue SW and SW 271h Street, whereas, Phase II is located at the southeast corner (Figure 1). The project includes the construction of a 5-lane road with bike lanes, curbs, gutters, and sidewalks from SW 16th Street to SW 19th Street, a 3-lane road with curbs, gutters, and sidewalks from SW 19th Street to SW 27th Street, and two stormwater treatment systems at the Phase I and Phase II wetland mitigation locations. This project is located adjacent to and will at times result in discharges to Springbrook Creek, which is located east of both the Phase I and II stormwater treatment systems. 2.1 Springbrook Creek Springbrook Creek is on the current 2002/2004 303(d) list of impaired water bodies for exceeding water quality standards for fecal coliform, dissolved oxygen, and sediment bioassay. 3.0 WATER QUALITY SAMPLING AND TESTING METHODS Water quality monitoring was conducted in accordance with the Department of Ecology's Order #1999-4-01497 Section A. 3.1 Sampling Parameters Stormwater samples were tested for the following seven parameters: • pH • Nitrate+Nitrite Nitrogen • Temperature • Total Suspended Solids • Turbidity .

Chain -of -custody documentation was completed upon sample delivery to the laboratory, and a copy of the documentation was given to Talasaea for reference. Turnaround time for the testing results was approximately 2 weeks. 4.0 RESULTS AND DISCUSSION The water quality and sediment sampling was conducted on 20 May 2005 at the upstream and downstream locations of the Phase I and II stormwater treatment systems. The weather at the time of sampling was cloudy with patches of thunder and lightning rain showers. Furthermore, rainfall occurring in the preceding week as measured at SeaTac International Airport totaled 1.44 inches, with 0.82 inches of that occurring in the two days before sampling. Analytical test results are presented in Appendix A, and are summarized in Table 2. Table 2.

The other parameters, including pH, total suspended solids (TSS), turbidity, Nitrate+Nitrite, fecal coliform, and total zinc were analyzed by an accredited laboratory. Hardness was analyzed to obtain zinc thresholds. At the time that samples were collected at the Renton Phase I and II stormwater treatment systems, the revised 2003 Washington State Department of Ecology (DOE) Surface Water Quality Standards had not been approved by the Environmental Protection Agency for the aforementioned parameters. For this reason, water quality parameters were compared with the 1997 Washington State Department of Ecology Surface Water Quality Standards (WAC 173-201A) for Class A (excellent) waters. 7 August 2005 Talasaea Consultants, Inc. 674-WQCM3-2005.doc Page 3 City of Renton Phase I and II Stormwater Treatment System Water Quality Monitoring Report Water Temperature Slight variations in water temperature occurred between the upstream and downstream locations of the stormwater treatment systems. However, all water temperatures measured at the site complied with DOE water quality standards where water temperature shall not exceed 18.0 °C. pH One of the most significant environmental impacts of pH is the effect that it has on the solubility and thus the bioavailability of chemical substances. During our last sampling event, which occurred 20 March 2003, the pH level at the Phase II upstream location was below DOE standards (pH=5.89), which states that pH shall be between 6.5 and 8.5 standard units. This was attributed to a recent rainfall. However, all sample locations collected during this most recent sampling event exhibited pH levels that are compliant to DOE standards. Total Suspended Solids Total suspended solids (TSS) are a measure of the amount of organic and mineral particles suspended in water. TSS results for the Phase I North indicated a decrease in TSS through the system. A trend similar to that recorded during the 20 March 2003 sampling event. However, at the Phase I South and Phase II systems, downstream TSS levels were measured slightly higher than the upstream TSS levels. This increase in TSS levels is believed to be due to significant rain events occurring within the preceding 10 days, in specific; 0.63 inches occurring on 10 May 2005, 0.37 inches occurring 16 May 2005, and 0.59 inches occurring 19 May 2005 that likely flushed the upstream locations and concentrated suspended solids at the downstream locations. Turbidity Turbidity also measures the amount of particles suspended in water by measuring the amount of scattered light from a sample. Turbidity at the downstream locations of the stormwater treatment systems complied with DOE standards, which states that turbidity levels shall not exceed 5 NTU (Nephelometric Turbidity Units) over background. Trends identified from the turbidity sampling were similar to that previously identified from the TSS sampling. This trend illustrates that turbidity levels decreased approximately 51 % from the upstream to downstream locations at the Phase I North system. However, turbidity increased from the upstream to downstream locations at the Phase I South and Phase II systems by 86% and 29% respectively. The measured increases from upstream to downstream locations at the Phase I South and Phase II systems, is believed to be due to a similar explanation as given in the TSS monitoring described above. Nitrate+Nitrite Nitrogen -containing compounds act as nutrients in streams, rivers, and reservoirs. The major routes of entry of nitrogen into bodies of water are municipal and industrial wastewater, septic tanks, feed lot discharges, animal wastes (including birds and fish), runoff from fertilized agricultural field and lawns and discharges from car exhausts. Bacteria in water quickly convert nitrites to nitrates and this process uses up oxygen. Excessive concentrations of nitrites can produce a serious condition in fish called "brown blood disease". Nitrate+Nitrite analysis showed no detectable concentrations at the downstream locations of the stormwater treatment systems. Nitrate+Nitrite was detected at the upstream locations of both Phase I South and Phase I North system. 7 August 2005 Talasaea Consultants, Inc. 674-WQCM3-2005.doc Page 4 City of Renton Phase I and II Stormwater Treatment System Water Quality Monitoring Report Fecal Coliform Fecal coliform bacteria are a collection of relatively harmless microorganisms that live in large numbers in the intestines of both exothermic and endothermic animals, including man. Fecal coliform bacteria generally indicate the presence of sewage contamination of a waterway and the possible presence of other pathogenic organisms. Fecal coliform concentrations measured from the Phase I South system shows a reduction from upstream to downstream sample locations with both locations in compliance with DOE standards (<100 colonies/100 mQ. However, Phase I North and Phase II systems exhibited fecal coliform concentrations well above DOE standards at both upstream and downstream locations. The elevated concentrations of fecal coliform in these two systems may be due to fecal material from wildlife, such as waterfowl. A nesting Canada goose was observed during the sampling at the Phase II downstream location, while other birds (i.e., mallards and red - winged blackbirds) were observed at both Phase I North and Phase II systems. Zinc Total zinc analysis showed a decrease in zinc concentrations from upstream to downstream locations throughout the stormwater treatment systems. Total zinc concentrations at all locations of the stormwater treatment systems collected and adjusted for water hardness per DOE standard calculations. The results of these calculations were that all total zinc samples were well below DOE standards at all sample locations, except for the Phase I North upstream location. The Phase I North upstream location was above DOE acute threshold for total zinc. However, total zinc was effectively sequestered by downstream location so that total zinc levels were compliant with DOE standards. 4.2 Sediment Samples The sediment samples were analyzed for total metals using EPA method 6010B, 200.8 and 7471A (Priority Pollutant Metals). Results are presented in Table 3. Sample concentrations were compared to the DOE freshwater sediment guidelines developed from the study titled Creation and Analysis of Freshwater Sediment Quality Values in Washington State. There are currently no State sediment standards for freshwater sediments. Detection limits were different for each sediment sample because the detection limits were dependent on soil moisture content of the sample and whether the sample required dilution for analysis. It was observed that each sample varied in soil moisture content. Sediment collected on 20 May 2005 at the Phase II upstream location did not provide a reliable sample due to the low percent of total solids collected (percent of total solids = 0.9%). As a result, very little solid material was available to analyze, which deteriorated the reliability of the sediment analysis. Despite the Phase II downstream location exhibiting soil conditions compliant with the DOE sediment guidelines for all analytes, there existed no reliable sample set to evaluate the effectiveness of the Phase II stormwater system. For this reason, sediment samples within the Phase II system were re -collected on 20 July 2005 to provide an accurate and reliable set of samples for comparison. The results from this analysis are provided in Table 4. 7 August 2005 Talasaea Consultants, Inc. 674-WQCM3-2005.doc Page 5 of Renton Phase I and II Stormwater Treatment System Water Quality Monitoring Report Table 3.

In addition, other analytes were detected within each stormwater system, although all downstream locations were found to have concentrations well below the DOE sediment guidelines, suggesting that each stormwater system is functioning effectively. Furthermore, all analytes were detected well below DOE sediment guidelines at upstream locations with the one exception occurring in Phase I North. Nickel levels measured from the Phase I North upstream location were 14 mg/kg higher than the DOE sediment guideline. However, as stated previously, the Phase I North stormwater system appears to be effective for sequestering nickel levels prior to release, as nickel levels were undetectable at the Phase I North downstream location. 7 August 2005 Talasaea Consultants, Inc. 674-WQCM3-2005.doc Page 6 City of Renton Phase I and II Stormwater Treatment System Water Quality Monitoring Report In terms of treatment performance and effectiveness, Phase I North and South sediment analyses generally showed a decrease in metals concentrations at the downstream locations indicating a positive treatment performance. Phase I North showed a slight increase in measured arsenic from upstream to downstream, although arsenic levels were still well below DOE Sediment Guidelines. Furthermore, arsenic, chromium, and nickel levels measured at Phase I South showed an increase from upstream to downstream, although downstream levels were still well below DOE sediment guidelines. Treatment performance and effectiveness within the Phase II stormwater system, as measured on 20 July 2005, also illustrated a generally positive treatment performance as metal concentrations decrease from upstream to downstream. The exceptions to this general trend is with concentrations of arsenic, chromium, and nickel, which increased slightly from upstream to downstream. However, as observed in each system, metals concentrations at release (downstream) locations remained well below the DOE sediment guidelines. More importantly, there is a decrease in the majority of metals concentrations at the downstream location, showing a general positive treatment performance throughout. The treatment performance for the metals is summarized in Table 5. The table summarizes the efficiency of the Phase I North and Phase II systems by determining the percentage of decrease or increase of measurable analyte from upstream to downstream location. The analytical test results are provided in Appendix A. Table 5.

Treatment performance analysis showed that the Phase I North stormwater treatment system is effectively reducing metals concentrations in sediments through the treatment train, with arsenic showing a slight increase at the downstream location. The Phase I South system appears to be the least effective system as arsenic, chromium, and nickel all increased from upstream to downstream locations. However, as previously stated, the measured concentrations at the downstream location are still well below DOE sediment guidelines. The Phase II system appears to be the most effective system at reducing metals concentrations. As mentioned above, all metal concentrations measured in downstream locations were well below DOE Sediment Guidelines. 7 August 2005 Talasaea Consultants, Inc. 674-WQCM3-2005.doc Page 7 of Renton Phase I and II Stormwater Treatment System Water Quality Monitoring Re In general, pollutant removal within the treatment systems is directly proportional to the time the stormwater remains in the treatment system (residence time) and the extent to which the stormwater comes in contact with vegetation and soil. Good soil and vegetation contact is required to promote the operation of mechanisms that sequester and/or chemically transform the pollutants into less toxic byproducts. By observation, stormwater velocity within each treatment system is reduced by spreading out the stormwater inflow into shallow, broad - bottomed, vegetated channels. This results in increased pollutant removal from increased stormwater residence time and increased contact of stormwater with vegetation and soil. 5.0 CONCLUSIONS Water quality and sediment testing at the City of Renton's Phase I and Phase II Stormwater Treatment Systems was conducted on 20 May 2005 and 20 July 2005. Samples were taken from the upstream (inflow) and downstream (outflow) locations of the stormwater treatment systems. Sample collected were promptly delivered to a DOE -accredited laboratory for analysis. Test results were made available approximately one week after sample collection. Stormwater sample analysis showed that water temperature, pH, turbidity, and total zinc complied with State Surface Water Quality Standards (WAC 173-201A) at all downstream locations. Nitrate+Nitrite nitrogen was undetectable at all outflow locations. In general, results showed that there were decreases in turbidity, total zinc concentrations, and Nitrate+Nitrite concentrations at downstream locations. Fecal coliform was measured well above State Surface Water Quality Standards at the Phase I North and Phase II systems. However, this is believed to have resulted from usage of the sites by waterfowl. Metals concentrations detected from downstream sediment samples were well below DOE's freshwater sediment quality guidelines. Treatment performance analysis showed that the Phase II system is most effectively reducing metals concentrations through the stormwater treatment train. However, as all downstream locations are well below DOE sediment quality guidelines, all three stormwater treatment systems are functioning as designed and are reducing metals concentrations sufficiently. 6.0 REFERENCES Cubbage, J., D.
