It originates on the Paccar property near the intersection of Garden Avenue North and North Fourth Street adjacent to Building 17 (Figure 1) and runs north along the east side of Garden Avenue North to the intersection North Sixth Street. At North Sixth Street, the drain turns west and runs down the centerline of North Sixth Street to the Cedar ' River. The drain has served as both an industrial waste discharge and a storm drain. While in ' operation, the Paccar plant discharged an estimated 0.08 MGD of contact cooling water from the foundry quench tanks, 0.06 MGD and 0.035 MGD of non-contact cooling water from two foundry melt furnaces and machinery, respectively to the Garden Avenue North/North Sixth ' Street drain under its National Pollution Discharge Elimination System (NPDES) permit. The drain also collects runoff from approximately 5 acres at the Paccar site including the northern half of the foundry building roof and from mostly paved surfaces east and north of the foundry ' building. In addition, the drain receives runoff from numerous catch basins along Garden Avenue North and North Sixth Street. Industrial waste discharges were discontinued in 1988 when the plant shutdown. The drain currently continues to collect runoff from the Paccar site ' and adjacent roadways. Sediment deposits have accumulated in the manholes and drain lines. As part of routine ' maintenance operations, the City of Renton plans to clean and repair any damaged sections of the drainage system. Because many pollutants tend to adhere to particulate material, storm drain sediments can often contain elevated concentrations of some pollutants, including metals and ' organic compounds. To characterize conditions in the storm drain prior to cleaning, sediment samples were collected from key locations in the drainage system and analyzed for chemical contaminants of concern. The goals of the Garden Avenue North/North Sixth Street storm ' system sediment sampling project included the following: ■ Characterize the chemical composition of sediment that has accumulated in ' the storm drain system and evaluate appropriate disposal options ■ Determine whether sediments pose a potential health hazard to City crews ' ■ Aid in identifying possible sources if the sediments in the drain are found to be contaminated. SAMPLING PROCEDURES Storm drain sediment sampling locations and sampling procedures, data quality assurance procedures, and health and safety procedures implemented as part of the sediment sampling program were previously described in the Quality Assurance Project Plan (Herrera 1993) and are summarized below: 289A\QAREPT 1 Herrera Environmental Consultants BOEING Station 2 Station 3LL El 0 15..

Garden Avenue North/North 6th Street drainage system. ' Sediment samples were collected from two manholes on the Garden Avenue North/North Sixth Street storm drain (Figure 1) to characterize potential contamination and sediment quality. These stations were selected based on a field reconnaissance survey conducted on August 25, 1993 and are described as follows: ' ■ Station 1. Manhole located on the east side of Garden Avenue North near the north end of Paccar building 17 (Figure 1). This station coincides with Paccar's former NPDES monitoring station and is the most upstream manhole on the drain that is accessible for sampling. Contributions from the Paccar industrial discharge, Paccar site runoff, and Garden Avenue North street runoff would be represented at this station. Sediment at this station appeared to consist of fairly rained sands and PP Y coarse g gravel with a considerable amount of rock and concrete debris present. ' Orange staining indicative of iron bacteria was also observed in the sediment at this location. ' ■ Station 2. Manhole located on North Sixth Street at the intersection with Burnett Avenue North approximately 3,500 feet downstream of Station 1. Sediment at Station 2 is visibly different from the sediment at Station 1, 1 consisting primarily of a brown fine silty sand. Station 2 is located near the downstream end of the drainage system about 1,800 feet upstream of the outfall in the Cedar River. The drainage system below Burnett Avenue is not well defined and based on recent dye tests, it is unclear which of the remaining manholes on North Sixth Street between ' Burnett Avenue and the Cedar River are connected to the Garden Avenue North/North Sixth Street drain. Sediment samples collected from Stations 1 and 2 were analyzed for the following parameters: ■ Total solids ' ■ Particle size ■ Total petroleum hydrocarbons (HCID followed by WTPH-G, WTPH-D, and Method 418.1 as necessary) ' ■ Priority pollutant metals (antimony, arsenic, beryllium, cadmium, chromium, copper, mercury, lead, nickel, silver, selenium, thallium, and zinc). rA single composite sample was also collected to assess disposal options. This sample consisted ■ of a composite derived from grab samples collected at the following three stations: ■ Station 1 (same as above) ■ Station 2 (same as above) ■ Station 3: Manhole at the intersection of Garden Avenue North and North Wells Avenue. This station is located approximately midway between Stations 1 and 2 (see Figure 1). 289A\QAREPT 3 Herrera Environmental Consultants ' The composite sample was archived until the metals results from the individual grab samples p P g p ' collected at Stations 1 and 2 were completed. AIR MONITORING ' Prior to collectingthe sediment samples, air quality in the manhole at each sampling station was P � q Y P g monitored using field instruments to assess potential hazards to city personnel who may need to enter the manholes to clean and repair the system. The following parameters were measured at each station: ■ Oxygen (percent) ■ Combustible gas (as percent of lower explosive limit) ■ Total organic vapors (using a photoionization detector [PID]) ' ■ Carbon monoxide (ppm) ■ Hydrogen sulfide (ppm). ' RESULTS ' Analytical testing results obtained from the sediments at Stations 1 and 2 of the Garden Avenue North/North Sixth Street drain are presented in Table 1. These results are discussed below with regard to disposal options, potential health hazards, and potential sources of those contaminants ' identified. Laboratory data were validated according to the objectives and procedures described in the ' sampling and quality assurance plan. No analytical problems or limitations or the use of the data were identified (Appendix Q. ' Metals ' The concentration of metals detected were (where appropriate) compared to cleanup levels identified by the Washington State Department of Ecology Model Toxics Control Act (MTCA) Cleanup Regulation (WAC 173-340). The following metals exceeded the MTCA soil cleanup ' level (Method A) at Stations 1 and 2; arsenic, chromium, and lead. Cadmium exceeded the MTCA cleanup level at Station 2 (see Table 1). Using a worst case assumption regarding the solubility of the concentrations of those metals observed, the initial concentrations of lead and cadmium observed in the dram sediments were found to be present at levels which could exceed WDOE criteria established for dangerous ' waste. Therefore, additional testing was requested for these sediments using the toxicity characteristic leaching procedure (TCLP) to determine whether the sediments in the drain classify as dangerous waste under WAC 173-303. Thus, the archived composite sample, which ' was comprised of the individual grab samples from Stations 1, 2, and 3, was submitted to the laboratory for further analysis.

Therefore, disposal at an approved landfill (e.g., Cedar Hills) is allowable. ' Table 2. Toxicity characteristic leaching Procedure (TCLP) testing results for the Garden Avenue North/North Sixth Street storm drain sediments. ' Composite Sample TCLPa Analyte Results (mg/L) Criteria (mg/L) Arsenic 0.05 5.0 Barium 0.950 --- Cadmium 0.002 1.0 Chromium 0.005 5.0 Lead 0.03 5.0 Mercury 0.0001 0.2 Selenium 0.05 1.0 Silver 0.003 5.0 ' a WAC 173-303 ' Total Petroleum Hydrocarbons ' The results from the WTPH-HCID analysis indicated that diesel and oil were present in the sediment at both Stations 1 and 2; Station 1 also contained gasoline. The HCID analyses is a qualitative screening method used to identify the type of petroleum hydrocarbons present in each sample so that the appropriate quantitative methods required to evaluate compliance with regulatory standards can be performed. Because gasoline, diesel, and oils, were positively identified in the sediment samples, additional analyses (WTPH-G, WTPH-D, and 418.1) were ' requested. The results, presented in Table 1 show that the concentrations of diesel (WTPH-D) and total petroleum hydrocarbon (TPH) (Method 418.1) in sediment samples collected from Stations 1 and 2 exceed the MTCA cleanup levels for soil (200 mg/kg). In addition, sediment at Station 1 exceeds the MTCA cleanup level for gasoline (100 mg/kg). The WTPH-D method measures the concentration of petroleum products ranging from kerosene through fuel oil #2. Method 418.1 covers Bunker-C, lubricating oils, as well as diesel. ' Because the concentrations of diesel and TPH are greater at the downstream station (Station 2) than at Station 1, it does not appear that the Paccar site is the primary source of these contaminants. The elevated gasoline observed at Station 1 may be contributed in part from the ' Paccar site. However, catchbasins along Garden Avenue North also discharge to the Garden Avenue North/North Sixth Street drain upstream of Station 1. Therefore, roadway runoff may also contribute to the gasoline contamination found at Station 1. ' 289A\QAREPT 6 Herrera Environmental Consultants Disposal Options ' Although the concentration of petroleum hydrocarbons present in these storm drain sediments exceeds the MTCA cleanup level for total petroleum hydrocarbons, the levels do not exceed the dangerous waste criteria as per WAC 173-303. Thus, these sediments may be disposed of at an approved landfill such as the Cedar Hills landfill in King County. King County Disposal Requirements. Wastes must be approved for disposal by the Seattle-King ' County Health Department before they will be accepted at the Cedar Hills landfill. Wastes containing less than 3 percent TPH are accepted at the landfill and wastes containing greater than 3 percent TPH may be accepted, although these more highly contaminated wastes are typically segregated and disposed separately from the garbage (Burke 1993 personal communication). Total petroleum hydrocarbon concentrations in the Garden Avenue North/North Sixth Street drain sediments are well below 3 percent. Therefore, sediment removed from the drain would ' likely be accepted for disposal by the Health Department. Prior to disposal, generator's waste profile sheet, certification of representativeness, and waste ' clearance application forms must be submitted and approved by the Health Department. Copies of the appropriate application forms are provided in Appendix B. ' Air Quality ' Field instruments were used to monitor air quality within each of the manholes (i.e., Stations 1, 2, and 3) at the time sediments were collected for analysis. The air monitoring results are presented in Table 3. ' Field measurements at Station 1 indicated a total organic vapor concentration of 4.1 ppm. This reading was recorded just above the sediment surface which was also noted to be stained black and to have a strong hydrocarbon odor. At Station 2 a total organic vapor reading of 10.3 ppm was observed. Except for carbon ' monoxide (CO) at 4 ppm, all other instrument readings were comparable to background. At Station 3, air quality readings were identical to Station 2, however, battery failure on the ' photoionization detector (PID) resulted in no measurement of total organic vapor for this station. Table 3. Air quality monitoring results from the Garden Avenue North/North Sixth ' Street storm drain. Parameter Background Station 1 Station 2 Station 3 ' Oxygen 20.9% 20.9% 20.9% 20.9% Hydrogen sulfide 0.0 ppm 0.0 ppm 0.0 ppm 0.0 ppm Carbon monoxide 0.00 ppm 0.00 ppm 4.0 ppm 4.0 ppm ' Combustible gas (LEL) 0.0% 0.0% 0.0% 0.0% Total organic vapors (PID) 0.0 ppm 4.1 ppm 10.3 ppm NA ' NA = no measurement ' 289A\QAREPT 7 Herrera Environmental Consultants The air quality testing results indicate that entry into the manholes for maintenance or to remove ' sediments should not be a problem with regard to adequate oxygen, explosive gases, carbon monoxide, or hydrogen sulfide gas. However, the total organic vapor readings of 4.1 to 10.3 ppm suggest that additional precautions may be warranted when entering the storm drain. The ' PID meter that was used to measure organic vapor concentrations cannot distinguish individual organic compounds present in the manholes. The meter provides a measure of the total concentration of all organic compounds combined. Because sediment samples exhibited ' elevated concentrations of petroleum hydrocarbons, including gasoline, polycyclic aromatic hydrocarbons (PAH) and benzene, ethylbenzene, toluene, and xylene (component of gasoline) are the organic compounds most likely to be associated with the sediments in the storm drain ' system. PAH compounds include naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, indeno(1,2,3-c,d) pyrene, ' dibenzo(a,h)anthracene, and benzo(g,h,i)perylene. Potential health hazards associated with these compounds and other contaminants present in the storm drain sediments are described in the following section. Hazard Evaluation ' The primary routes of exposure to contaminants present in the Garden Avenue North/North Sixth Street storm drain sediments (metals, petroleum hydrocarbons) are inhalation, skin contact, ' dermal absorption, and ingestion. Symptoms of overexposure and occupational health standards for these contaminants are summarized in Table 4. Dermal absorption and ingestion can be controlled through use of proper personal protective clothing (i.e., boots, gloves, and coveralls) and decontamination procedures. Inhalation exposure can be minimized by ventilating the manhole prior to entry to reduce the concentration of the contaminant in the worker's breathing space and/or by wearing appropriate respiratory protection (i.e., air-purifying respirator). Although metals exposure can occur via inhalation, this pathway is not considered to be a serious threat to workers because the sediments in the manholes are typically wet, which reduces the potential for dust generation. Inhalation is of most concern for PAHs which are semi-volatile and for benzene which is highly volatile. ' Other potential hazards associated with confined space entry include oxygen-deficient and/or explosive conditions caused by the presence of other gases that may or may not be related to sediment contamination. Other potentially hazardous gases that may be present include carbon ' dioxide, carbon monoxide, methane, hydrogen sulfide, and ammonia. Although these gases are more common in sanitary sewers, they could be present in the Garden Avenue North/North Sixth Street drain. Possible sources of these gases include cross connections between the sanitary ' sewer and storm drain systems and organic material that may be degraded by bacteria present in the storm drain. Hazards associated with these additional gases that may be encountered in confined spaces are summarized in Table 5. 1 289A\QAREPT 8 Herrera Environmental Consultants Table 4.

Recommendations ' It is recommended that city crews follow procedures for confined space entry as described in Part M of WAC 296-62 when working in the Garden Avenue North/North Sixth Avenue storm drain. Part M requires that ventilation be maintained at all times when working in a confined ' space. Air monitoring for combustible gas, organic vapors, carbon monoxide, benzene, and hydrogen sulfide levels in the breathing space within the manhole should be conducted prior to entry to evaluate the effectiveness of the ventilation equipment. Under no circumstances should workers enter a manhole if air quality in the manhole does not meet the following criteria: ■ Oxygen: greater than or equal to 19.5 percent and less ' than 23 percent ■ Lower explosive limit (LEL): less than 20 percent of the LEL ■ Carbon monoxide: less than 200 ppm ■ Hydrogen sulfide: less than 10 ppm ■ Organic vapor: less than 5 ppm above background. ' Ventilation and air quality monitoring should be conducted continuously while workers are in the manhole. Workers should immediately exit the manhole if the ventilation or air monitoring equipment becomes inoperative. Under certain limited circumstances, respiratory protection in the form of an air-purifying respirator (APR) may be used to permit safe entry if ventilation does not adequately reduce the ' concentration of organic vapors in the manhole. However, the criteria for all of the other air quality parameters of concern listed above (e.g., oxygen, combustible gas, hydrogen sulfide, and carbon monoxide) must be met before use of an APR can be considered. An APR equipped with ' an organic vapor cartridge will provide adequate protection against many organic compounds, but is inadequate for oxygen deficient environments, explosive conditions, and for carbon monoxide and hydrogen sulfide. It is recommended that workers wear an APR if the concentration of organic vapor in the manhole after ventilation is greater than 1, but less than 5 ppm above background and all other air quality criteria are met. APRs are not recommended in situations where the organic vapor concentration exceeds 5 ppm above background. Under these ' conditions, a supplied-air system such as a self-contained breathing apparatus (SCBA) would be required to permit safe entry into the manhole. WAC 296-62-071 requires that employers implement a respiratory protection program before respirators are used to control worker exposure to air contaminants. Minimum requirements for a respiratory protection program described in WAC 296-62-071 include preparation of written ' standard operating procedures, medical clearance documenting that workers are physically able to perform the work and use the equipment, implementation of a training program with annual updates, workers must be fit tested, respirators maintenance and inspection requirements, implementation of a medical surveillance program, and annual program evaluation. Under WAC 296-62-30, workers required to wear SCBA equipment on the job must have 80 hours of training and a minimum of three days actual field experience under the direct supervision of a trained, experienced supervisor. Other safety equipment and clothing that should be used by workers when entering the manhole ' include: ' 289A\QAREPT 12 Herrera Environmental Consultants ■ Tripod and winch with approved safety harness ■ Chemical resistant boots, coveralls, and gloves ■ Hardhat ■ Safety goggles. The city should also prepare a health and safety checklist prior to beginning work in the Garden Avenue North/North Sixth Street drain. This checklist should describe emergency procedures, communication protocols, and designate a site health and safety officer who will be responsible for implementing the procedures described in the checklist. All workers should fully understand and be prepared to implement the health and safety procedures. REFERENCES ' Burke, S. August 24, 1993.

It originates on the Paccar property near the intersection of Garden Avenue North and North 4th Street adjacent to Building 17 (Figure 1) and runs north along the east side of Garden Avenue North to the intersection North 6th Street. At North 6th Street, the drain turns west and runs down the centerline of North 6th Street to the Cedar River. ' The drain has served as both an industrial waste discharge and a storm drain. While in operation, the Paccar plant discharged an estimated 0.08 MGD of contact cooling water from the ' foundry quench tanks, 0.06 MGD and 0.035 MGD of non-contact cooling water from two foundry melt furnaces and machinery, respectively to the Garden Avenue North/North 6th Street drain under its National Pollution Discharge Elimination System (NPDES) permit. The drain ' also collects runoff from approximately 5 acres at the Paccar site including the northern half of the foundry building roof and from mostly paved surfaces east and north of the foundry building. In addition, the drain receives runoff from numerous catch basins along Garden ' Avenue N. and N. 6th Street. Industrial waste discharges were discontinued in 1988 when the plant shutdown. The drain currently continues to collect runoff from the Paccar site and adjacent roadways. Sediment deposits have accumulated in the manholes and drain lines. As part of routine maintenance operations, the City of Renton plans to clean and repair any damaged sections of the drainage system. Because many pollutants tend to sorb onto particulate material, storm drain sediments can often contain elevated concentrations of some pollutants, including metals and organic compounds. To characterize conditions in the storm drain, sediment samples will be ' collected from key locations in the drainage system prior to cleaning. The following goals have been identified for the Garden Avenue North/North 6th Street storm system sediment sampling project: ' ■ To characterize the chemical composition of sediment that has accumulated in the storm drain system and evaluate appropriate disposal options ' ■ To determine whether sediments pose a potential health hazard to City crews ■ To aid in identifying possible sources if the sediments in the drain are found to be contaminated. ' This report describes the sampling locations and sampling procedures, data quality assurance procedures, and health and safety plan that will be implemented as part of the sediment sampling program. PROJECT ORGANIZATION AND QUALITY ASSURANCE RESPONSIBILITIES ' Herrera Environmental Consultants, Inc. is responsible for conducting all sediment sampling, data quality review, and evaluation.

Jeff Reitan Manuel Vieira ' Figure 2 - Project organization and quality assurance responsibilities. ' SAMPLING PLAN SAMPLING STATIONS The sampling program entails collecting sediment samples and performing air monitoring at select manholes on the Garden Avenue North/North 6th Street storm drain. A brief field reconnaissance of the system was conducted on August 25, 1993 to aid in the selection of sampling stations. The field survey was used to verify manhole locations, address accessibility issues, and to assess whether a sufficient amount of sediment was present at the preferred ' sampling locations. Sediment samples will be collected from the following two stations to characterize sediment ' quality: ■ Station 1. Manhole located on the east side of Garden Avenue North near the ' north end of Paccar building 17 (Figure 1). This station coincides with Paccar's former NPDES monitoring station and is the most upstream manhole on the drain that is accessible for sampling. Contributions from the Paccar industrial discharge, Paccar site runoff, and Garden Avenue North street runoff would be represented in this sample. ' Sediment at this station appeared to consist of fairly coarse grained sands and gravel with a considerable amount of rock and concrete debris present. Orange staining indicative of iron bacteria was also observed in the sediment ' at this location. ■ Station 2. Manhole located on North 6th Street at the intersection with ' Burnett Avenue North approximately 3,500 feet downstream of Station 1. Sediment at Station 2 is visibly different from the sediment at Station 1, consisting primarily of a brown fine silty sand. ' Station 2 is located near the downstream end of the drainage system about 1,800 feet upstream of the outfall in the Cedar River. The drainage system below Burnett Avenue is not well defined and based on recent dye tests, it is unclear which of the remaining manholes on North 6th Street between Burnett Avenue and the Cedar River are connected to the Garden Avenue North/North ' 6th Street drain. Sediment samples will be analyzed for the following parameters: ■ Total solids ■ Grain size ■ Total petroleum hydrocarbons (HCID followed by WTPH-G, WTPH-D, and Method 418.1 as necessary) ■ Priority pollutant metals (antimony, arsenic, beryllium, cadmium, chromium, copper, mercury, lead, nickel, silver, selenium, thallium, and zinc). ' 289A\QAPLAN2 5 Herrera Environmental Consultants, Inc. A single composite sample will also be collected to assess disposal options. This sample will be composited from grab samples collected at the following three stations: ■ Station 1 (same as above) ' ■ Station 2 (same as above) ■ Station 3: Manhole at the intersection of Garden Avenue North and North Wells Avenue. This station is located approximately midway between ' Stations 1 and 2. The composite sample will be archived until the metals results from the individual grab samples ' collected at Stations 1 and 2 are completed. If the metals concentrations in sediment from Stations 1 or 2 exceed the Model Toxics Control Act (MTCA) cleanup levels for soil, the composite sample will be submitted for metals analysis by the toxicity characteristic leaching ' procedure to determine whether the sediments in the drain classify as dangerous waste under WAC 173-303. ' SAMPLING PROCEDURES ' The field coordinator will review sampling procedures with the field technicians, prepare a list of field equipment, and check and calibrate all necessary field meters. This section identifies specific procedures for collecting sediment samples from the storm drain, monitoring air quality ' in the drainage system, decontaminating sampling equipment, and preparing field notes. It also describes requirements for sample containers and preservation, sample identification, sample transport, and sample custody. Sediment Sample Collection ' Samples will be collected at manholes where the storm drain lines are accessible. If possible, samples will be collected from street level using a stainless steel scoop attached to a telescoping ' pole to avoid having to enter the manhole. Sediment will be placed in a stainless steel mixing bowl. Sediment characteristics (e.g., texture, color, debris, oily sheen, and odor) will be recorded in the field notebook. After debris and gravel larger than 2 centimeters is discarded, ' the sample will be thoroughly mixed, and the homogenized sample will be transferred to prelabeled sample containers. All samples will be immediately placed on ice in a cooler. ' If samples cannot be collected using the long-handled scoop, one crew member will enter the manhole to collect the sample. If necessary, sediment can be scraped from the bottom and sides of the manhole to obtain the necessary sample volume. Procedures for manhole entry are ' described in the Health and Safety Plan. Air Monitoring Prior to collecting the sediment samples, air quality in the manhole at each sampling station will be monitored using field instruments to assess potential hazards to city personnel who may need 289A\QAPLAN2 6 Herrera Environmental Consultants,Inc. ' to enter the manholes to clean and repair the system. The following parameters will be measured at each station: ■ Oxygen (percent) ■ Combustible gas (as percent of lower explosive limit) t ■ Total organic vapors (using a photoionization detector) ■ Carbon monoxide (ppm) ■ Hydrogen sulfide (ppm). ' Air quality measurements will be collected near the bottom of the manhole to assess conditions in the air space that will be occupied by city crews when working on the drainage system. Field ' instruments will be lowered in a bucket to the bottom of the manhole to take the readings. All measurements will be recorded in the field notebook. ' Field Notes ' At each sampling station, the following information will be recorded in a waterproof field notebook: ' ■ Sampling date ■ Time of sample collection ■ Station location ' ■ Name of sampler ■ Weather and flow conditions ■ Unusual conditions (e.g., oily sheen, color, turbidity, discharges) ' ■ Calibration results for field instruments ■ Field measurements ■ Number and type of samples collected ■ Unusual sampling procedures. Upon return to the office, field notes will be copied and inspected by the QA officer. Sample Containers, Preservation, and Holding Times Precleaned sample containers will be obtained from the analytical laboratory for the required analyses. Spare sample containers will be carried by the sampling team in case of breakage or ' possible contamination. Sample containers, preservation techniques, and holding times are described in Table 1. ' Sample Identification and Labeling ' Each sample will be identified by a unique station number and the date of collection. Prior to filling, sample containers will be labeled with the following information using indelible ink: ' ■ Station number ' 289A\QAPLAN2 7 Herrera Environmental Consultants,Inc. Table 1.

A chain-of-custody record will accompany the samples (Appendix A). Upon return to the office, a signed copy of the chain-of-custody record will be inspected by the QA officer. i Decontamination 1 All sampling equipment (e.g., spoons, mixing bowls, long-handled scoop) will be decontaminated prior to use at each station according to the following procedures: 1 1) Scrub with soapy water (Alconox solution) 2) Rinse six times with tap water 1 3) Rinse with 6N nitric acid 4) Rinse with methanol 5) Rinse six times with deionized water. 1 All washwaters will be disposed of in a sanitary sewer. 1 Protective clothing (e.g., Tyvek suits, gloves) used on this project is not considered to be contaminated and will be bagged and disposed of in standard solid waste collection containers located offsite. 1 SCHEDULE 1 Site reconnaissance and sampling of the selected manholes will be completed during August 1993. Samples will be delivered to the laboratory within 6 hours of collection. Data will be 1 reported by the laboratory within 30 days. Data will be quality assured by the QA officer within 14 days. The draft report is scheduled for completion in October. i 1 1 1 289A\QAPLAN2 9 Herrera Environmental Consultants,Inc. ' DATA QUALITY ASSURANCE PLAN QUALITY CONTROL OBJECTIVES The overall quality assurance objective is to develop and implement procedures for field sampling, laboratory analysis, and reporting that will provide sound scientific data. All measurements will be performed to yield consistent results that are representative of the media and conditions measured. Specific objectives and procedures for precision, accuracy, representativeness, completeness, and comparability are identified below: ■ Detection limits for the analytical methods used in this study are summarized in Table 2. ■ Precision will be assessed using laboratory duplicates. The relative percent difference (RPD) of laboratory duplicates will + 25 percent for values that are ' greater than 5 times the detection limit, and + 2 times the detection limit for values that are less than or equal to 5 times the detection limit. Laboratory duplicates will be analyzed at a frequency of at least 5 percent of the total ' number of samples submitted. ■ Accuracy will be assessed with analyses of laboratory preparation blanks, matrix spikes, and control standards. The values for blanks will not exceed 2 times the detection limit. The percent recovery of matrix spikes will be between 75 and 125 percent. The percent recovery of control standards will ' be between 90 and 110 percent. The laboratories will analyze a preparation blank with every sample batch. The laboratories will analyze matrix spikes and standard solutions at a frequency of at least 5 percent of the total number ' of samples submitted. ■ Representativeness of the sediment samples collected from the Garden Avenue North/North 6th Street storm drain will be ensured by employing consistent and standard sampling procedures. ' ■ Completeness is expressed as the ratio of the number of valid sample results to the total number of samples analyzed by the analytical laboratory. The objective for this study is a minimum of 95 percent completeness. It is anticipated that all samples will be collected because field reconnaissance will eliminate locations having problems with access or sample collection. In addition, an equipment checklist will prevent loss of data from missing containers or inoperable meters. ■ Data comparability will be ensured through the application of standard ' sampling procedures, analytical methods, units of measurement, and detection limits. The results will be tabulated in standard spreadsheets for comparison with criteria and historical data. ' 289A\QAPLAN2 10 Herrera Environmental Consultants,Inc. ' Table 2.

These methods will provide detection limits that are below the state and federal regulatory criteria or guidelines, to enable direct comparison with these criteria. ' Analytical methods are presented in Table 2. The laboratory identified for this project is certified by Ecology and participates in audits and ' interlaboratory studies by Ecology and U.S. EPA. These performance and system audits have verified the adequacy of the laboratory standard operating procedures, which include preventive maintenance and data reduction procedures. The laboratory will report the analytical results within 30 days of receipt of the samples. Sample and quality control data will be reported in a standard format. The reports will also include a ' case narrative summarizing any problems encountered in the analyses. CORRECTIVE ACTIONS Field and laboratory results will be assessed by the QA officer, who will take appropriate ' corrective actions. Quality control problems and corrective actions will be summarized in a QA worksheet (Appendix B). Values associated with minor quality control problems will be considered estimates and flagged with a "J". Values associated with major quality control ' problems will be rejected and flagged with an "R". Estimated values may be used for evaluation purposes, while rejected values will not be used. This section describes the data assessment procedures for the following quality control elements: ' ■ Completeness ■ Methodology 1 ■ Holding times ■ Detection limits ■ Blanks ' ■ Laboratory duplicates ■ Matrix spikes ■ Control standards. Completeness ' Completeness will be assessed by comparing valid sample data with this QA project plan and the chain-of-custody records. Completeness will be calculated by dividing the number of valid values by the total number of values. Samples will be reanalyzed or re-collected if completeness is less than 95 percent. 289A\QAPLAN2 12 Herrera Environmental Consultants, Inc. Methodology ' Methodology will be assessed by examination of the field notebook and laboratory reports for deviation from the QA project plan. Unacceptable deviations will result in rejected values and will be corrected in future analyses. Holding Times ' Analysis dates and times will be reported by the laboratory. Holdingtimes will be assessed b Y comparing analytical dates and times to sample collection dates and times. Values that exceed the maximum holding time required by U.S. EPA (1992) (see Table 1) will be considered estimates. In some cases, the magnitude of the holding time exceedance may warrant rejection of the reported values. Sensitivity to holding time exceedances and impacts on analytical results ' are different for each pollutant compound. Therefore, holding time exceedances will be evaluated separately for each pollutant analyzed. Blanks ' Preparation blank values will be reported in each laboratory report. Sample values that are less than 5 times a detected blank value will be considered estimates. ' Detection Limits ' Detection limits will be recorded in each laboratory report. If proposed detection limits are not met by the laboratory, the laboratory will be requested to reanalyze the samples and/or revise the method if time permits. Laboratory Duplicates Precision of laboratory duplicate results will be presented in each laboratory report and checked by the QA officer. Data for batch samples (i.e., samples from other projects analyzed with ' samples from this project) will be acceptable as long as duplicates are analyzed at a frequency of at least 5 percent. Precision of laboratory duplicate results will be calculated according to the following equation: RPD = ' (CI + C2) /2 where: ' RPD= relative percent difference C 1 = larger of two values C-� = smaller of two values. r 289A\QAPLAN2 13 Herrera Environmental Consultants, Inc. Results exceeding the objectives will be noted in the QA worksheets, and associated values will be flagged as estimates (J). If the objectives are severely exceeded (e.g., more than twice the ' objective), then associated values will be rejected (R). Matrix Spikes Accuracy of matrix spike results will be presented in each laboratory report and checked by the ' QA officer. Data for batch samples will be acceptable as long as spikes of project samples are analyzed at a frequency of at least 5 percent. Accuracy of matrix spike results will be calculated according to the following equation: ' (S-U) x 100% %R = ' Csa where: ' %R =percent recovery S =measured concentration in spike sample U =measured concentration in unspiked sample ' Csa =actual concentration of spike added. If the analyte is not detected in the unspiked sample, then a value of zero will be used in the ' equation. Results exceeding the objective will be noted in the QA worksheets, and associated values will be flagged as estimates (J). However, if the percent recovery exceeds 125 and a value is less than the detection limit, the result will not be flagged as an estimate. Nondetected values will be rejected if percent recovery is less than 30 percent. Control Standards ' Accuracy of control standards will be presented in the laboratory report and checked by the QA officer. Accuracy for these elements will be calculated according to the following equation: ' (M-T) x 100% %R = ' T where: ' %R =percent recovery M =measured value T =true value. Results exceeding the objective will be noted in the QA worksheets, and associated values will be flagged as estimates (J). If the objectives are severely exceeded (e.g., more than twice the ' objective), then associated values will be rejected (R). 289A\QAPLAN2 14 Herrera Environmental Consultants,Inc. ' QUALITY ASSURANCE REPORT Laboratory reports and QA worksheets will be included in the project report. Any problems and ' associated corrective actions taken will be reported. Specific QA information that may be noted in the report includes the following: ' ■ Changes in the monitoring/QA project plan ■ Results of performance and/or systems audits ■ Significant QA problems and recommended solutions ' ■ Data quality assessment in terms of precision, accuracy, representativeness, completeness, comparability, and detection limits ' ■ Discussion of whether the QA objectives were met, and the resulting impact on decision-making ' ■ Limitations on use of the measurement data. ' 289A\QAPLAN2 15 Herrera Environmental Consultants, Inc. ' SITE SPECIFIC HEALTH AND SAFETY PLAN INTRODUCTION ' This site-specific Health and Safety Plan is designed to advise and protect HEC employees from potential hazards associated with monitoring and collection of sediment samples from the ' Garden Avenue North/North 6th Street drain. Physical hazards due to traffic-related problems typically encountered when accessing manholes located along city streets and hazards associated with confined space entry, as well as potential chemical hazards associated with contaminated sediments are the primary concerns for the Garden Avenue North/North 6th Street drain. As described in the sampling plan, wherever possible, samples will be collected from above with ' sampling equipment attached to a telescoping rod to avoid having to enter the manhole. This eliminates potential hazards associated with confined space entry. However, it is possible that in some cases confined space entry may be required to obtain the necessary samples. For example, ' use of a long-handled scoop is only feasible when sediment deposits in the drain are relatively deep (greater than about 2 inches) and soft. When little sediment is available, or when sediments are tightly packed to the bottom of the pipe, it may be necessary to enter the manhole and ' manually scrape the sample from the sides and bottom of the manhole. Therefore, safe practices for confined space entry and emergency contingencies are documented in this plan. ' The following guidelines were used in developing this health and safety plan: ■ U.S. Environmental Protection Agency (EPA) Standard Operating Safety ' Guide (U.S. EPA 1984b) ■ Occupational Safety and Health Administration (OSHA) requirements for ' medical surveillance, personal protection, respirator fit testing, and hazardous waste operations training (29 CFR 1910) ■ General Occupational Health Standards for confined space entry (WAC 296- 62-145) ' ■ National Institute for Occupational Safety and Health standards (NIOSH 1979) ' ■ American National Safety Institute standard for confined space entry (ANSI Z117.1). All HEC employees participating in field activities will be required to follow the procedures set out in this plan. ' Safety requirements must also be met by all observers present during sampling activities. To help ensure safety compliance, all HEC field participants and observers must read this plan and agree to comply with all plan conditions. 289A\QAPLAN2 16 Herrera Environmental Consultants,Inc. tDELINEATION OF RESPONSIBILITIES Herrera Environmental Consultants, Inc. (HEC) will be responsible for adhering to the Health and Safety Plan and for'completing all tasks in the scope of work except for the following City of Renton obligations: ■ Traffic control support as required ■ Tripod/winch and ventilator equipment necessary for manhole entry. ' Other field personnel are fully trained as per WAC 296-62-3040, Part P, and are responsible for adherence to all aspects of this plan. Any modifications necessary to this plan must be approved ' by the site safety officer. The site safety officer will designate, in advance, the individual to act as onsite safety officer. This individual will have the authority to immediately suspend site operations if any potentially hazardous conditions exist. Under such circumstances, operations will not resume until remedial actions are agreed to by the project manager and the corporate health and safety officer. Table 3.

An effort will be made to ensure that there will be little or no interference with any vehicular traffic. The City of Renton has absolute authority over manhole access, operations scheduling, and timing of specific site controls. Site control will require exclusion of pedestrian traffic from close ' proximity to the manhole. ' 289A\QAPLAN2 17 Herrera Environmental Consultants, Inc. HAZARD ASSESSMENT ' The most likely potential hazards in a storm drain environment are of a physical nature within a confined space. However, it is also possible that the atmosphere within a confined space can become oxygen deficient or filled with explosive gases. The following subsections discuss these ' possibilities and methods for site control. ' Physical Hazards The most serious potential physical hazard will involve the possibility of falling inside stormwater manholes. Safety procedures will be implemented to reduce potential hazards and prevent injury. Entry procedures are described in a later section. ' Contaminant Hazard ' Within the selected storm drain/industrial waste line manholes, it is possible that contaminated materials will be encountered. Air monitoring for organic vapors, oxygen deficiency, carbon monoxide, hydrogen sulfide, and explosion potential will be conducted prior to entry and ' continuously while the manhole is occupied to evaluate atmospheric conditions and to determine safety equipment requirements. ' TRAINING REQUIREMENTS ' HEC will only allow personnel who have successfully completed 40 hours of health and safety training as required under 29 CFR Part 1910.120 to participate in the sampling of stormwater drains/industrial wastelines. If any circumstances arise which would require supplied air to ' samplers (Level B) then, only personnel who have completed 80 hours of health and safety training will be allowed to don Level B equipment and enter such an environment. ' The designated site safety officer will be trained and responsible for selecting the appropriate level of protection, air monitoring instruments and techniques, confined space entry procedures and all other field decisions required to safely complete the scope of work. PERSONNEL PROTECTION AND DECONTAMINATION ' Protective clothing will be worn to prevent contact with potentially contaminated materials within the Garden Avenue North/North 6th Street drain. There will be no entry if hazardous conditions exist in the storm drain. Initial monitoring of organic vapors, oxygen, carbon monoxide (CO), hydrogen sulfide (H2S), and explosive conditions will determine what level of protection is required. Under current conditions relative to the health and safety and sampling ' plans, only Level D and Level C are authorized. The following is a description of the authorized levels of protection: 289A\QAPLAN2 18 Herrera Environmental Consultants,Inc. Level D: Protective Clothing ■ Tyvek coveralls ' ■ Steel-toed, chemical-resistant boots ■ Hard hat (with head lamp in confined space) ■ Safety glasses/goggles, if necessary ' ■ Work gloves ■ Solvex gloves (when in contact with water or drain sediments). ' Safety Equipment ■ Air monitoring equipment (photoionization detector, combustible gas meter, ' 3-gas meter--02/CO/H2 S) ■ Eyewash ■ First aid kit ■ Waterproof flashlight. Level C: ' Protective Clothing ■ Negative pressure, full-faced respirator ■ Organic vapor/acid gas/high efficiency filter (HEPA) cartridges. Safety Equipment ■ Identical to Level D. Air Monitoring The following equipment will be used for air monitoring in confined spaces: ■ Three-gas meter (02/CO/H2S) Measures concentrations of oxygen (percent), carbon monoxide (ppm), and hydrogen sulfide (ppm) in the atmosphere ■ Combustible gas meter - Measures percentage of lower explosive limit (LEL) of gases in ' atmosphere ■ Photoionization detector (PID) - Measures concentration of organic vapors in parts per million (ppm) i ' 289A\QAPLAN2 19 Herrera Environmental Consultants,Inc. These instruments will be calibrated daily before field application per the manufacturer's specifications. The operating manuals for these instruments will be onsite at all times. ' Personnel entering the storm drains will, prior to entry, conduct air monitoring to accomplish the following objectives: t ■ Determine existing or potential hazards with immediate impact on site personnel ■ Establish baseline information for determining the safety requirements for entering storm drains. ' Background levels outside the manhole will be measured before determining levels within the confined space using the 3-gas meter, PID, and combustible gas meter. Before entering the manhole, conditions inside the manhole will be evaluated. If feasible, readings will then be taken through the manhole cover before opening it and then incrementally down to the potential working area. After the initial air quality readings are collected, the ventilation equipment will ' be inserted in the manhole and operated for a period of at least 5 minutes. A second set of readings will then be collected to evaluate air quality in the worker air space within the manhole. All readings will be entered into the field book. Action level criteria for personal protection are described in Table 4. ' Table 4. Decision Criteria for Upgrading Personal Protective Clothing. Monitoring Instrument Decision Level Protection Action ' PID 1 unit above U background grade to Level C g P ' protection PID 5 units above background Postpone work-Amend plan to ' include Level B protection 02 < 19.5% or> 23% Postpone work-Amend plan to include Level B protection CO 200 ppm Postpone work-Amend plan to ' include Level B protection ' H2S 10 ppm Postpone work-Amend plan to include Level B protection Combustible gas meter 20% LEL in atmosphere Postpone work-Reevaluate. 289A\QAPLAN2 20 Herrera Environmental Consultants,Inc. The atmosphere inside all vertical levels of the manholes must be continually monitored while workers are inside the space. If readings become elevated to Table 4 action levels, then ' personnel must exit the confined space. At such time, a decision will be made on how to appropriately continue. Confined Space Entry 1 This section discusses general requirements and detailed discussion of confined space entry. A three-person field crew is required for entry and work in a confined space environment. One person will be the worker inside the confined area. The second person will be a standby ' observer and the third person will be available in case of an emergency situation and for general assistance. Personnel Roles ' Sampler The sampler will be the individual actually located and performing work in the confined space. ' Standby Observer The standby observer will function as the key person during any confined space operations. Their duties include but are not limited to: ■ To remain in constant contact with the confined space worker. This person is ' not to leave the observation point while the worker remains in the confined space. ' ■ To remain outside the confined space under all circumstances. If the worker becomes incapacitated in any way, emergency procedures are to commence immediately. ' ■ To be familiar with proper usage of any/all safety equipment. ' ■ To act as the absolute authority over work activities. If any circumstances occur which may be potentially harmful to the sampler, the observer will instruct the sampler to vacate the confined space immediately until ' circumstances dictate safe re-entry. ' ' Third Person A third person will be present during confined space activities. Their role will be to: ' 289A\QAPLAN2 21 Herrera Environmental Consultants,Inc. ' ■ Operate air monitoring equipment ■ Be familiar with any and all safety equipment ' ■ Provide general assistance to other crew members ■ Contact emergency resources in case of emergency circumstances. ' The third person for this project may be a City of Renton employee or an HEC employee. Staffing assignments for this project will be identified prior to any field sampling event. This person will read and comply with all aspects of this plan. Entry Procedures The following equipment is required for confined space activities: ' ■ Manhole hook ■ Lighting equipment for the confined space worker (spotlights, headlamp, and batteries, etc.) ■ Portable telephone for emergency situations 1 ■ Air quality monitoring equipment (e.g., PID, combustible gas meter, 02/CO/H2S meter). Equipment must be well maintained and calibrated. ' Document the type of equipment used in the field notebook including entries from equipment calibration log. ' ■ Personal safety equipment (e.g., Tyvek suit, gloves, boots, hardhat, air- purifying respirator) ' ■ Sampling equipment (bucket, rope, bottles, stainless steel spoons) ■ Tripod, winch, safety harness, and ventilation equipment (to be provided by ' the City of Renton). After completing the initial air monitoring to assess ambient conditions in the manhole, the ' following procedures will be implemented to ensure safe entry: ■ Remove the manhole cover completely away from opening. ' ■ Install and operate ventilation equipment for at least 5 minutes before rechecking air quality conditions in the manhole with the field meters. ' Consult the decision criteria described in Table 4 to determine whether the manhole can be entered safely and to select appropriate protective equipment. Under no circumstances should manhole entry proceed if action levels are ' exceeded. 289A\QAPLAN2 22 Herrera Environmental Consultants,Inc. ' ■ Have the sampler don necessary protective clothing and equipment. Third person shall assist in outfitting procedures and check to ensure that all safety equipment is operable. ■ Measure the water level inside the manhole (if any). ' ■ Install tripod and winch above the manhole opening. ' ■ Attach the entry worker's safety harness to the tripod/winch. For entry, the worker should sit on the edge of the manhole facing the manhole rungs and test the integrity of the rungs with his/her foot before proceeding. Do not place both feet on the rungs at the same time until certain that the rungs are secure (if rungs are damaged, use ladder or winch for entry). ■ Upon reaching the bottom of the manhole, check footing and establish communications with standby observer before proceeding with sampling. ' ■ Have all tools and equipment lowered down via a rope and bucket. Once inside the manhole, verbally communicate to the standby observer any field observations ' including odors, signs of corrosion, oil sheen in any standing water, etc. The fieldbook will not be taken into the manhole. ' Communications Protocol ' Prior to beginning sampling activities in storm drains, personnel will be trained in the use of simple communication signals. This section addresses signals to be used by workers in confined spaces and by workers at field sampling locations. Most of the confined space sampling ' locations will not require the workers who enter the manhole to go beyond the point where visual contact can be maintained. The following signals are to be used when visual contact is maintained with workers inside confined spaces: ■ Hand clutching throat - out of air/can't breathe ■ Hands on top of head - needs assistance ' ■ Thumbs up - OK/I'm all right/I understand ■ Thumbs down - no/negative. ' Where visual contact cannot be maintained with the worker inside the confined space, the following signals should be used: ' ■ One tug on line from person outside space and one from person inside - the worker is ok ' ■ Three tugs on line from person inside space - worker needs to be removed from the confined space. 289A\QAPLAN2 23 Herrera Environmental Consultants,Inc. If at any time the observer does not receive a response from the worker inside the confined space, the observer 'will assume that an emergency situation exists and will immediately ' implement emergency procedures. Dangerous Conditions Work inside a confined space will cease immediately when any of the following conditions exist: ■ Illness or injury to the confined space worker ' ■ Failure of ventilation equipment, air monitoring equipment, or portable telephone ■ Severe weather conditions occur or are imminent. ' The atmosphere within a confined space will always be treated as being dangerous. ' Emergency Procedures ' The following procedures will be implemented to assure expedient emergency response. ■ All onsite HEC personnel will have read and comply with this site safety plan ' ■ HEC personnel will have a complete understanding of all field procedures before any field work occurs ' ■ The designated onsite safety officer will ensure that all necessary safety equipment is onsite each working day, including but not limited to, a well stocked first aid kit, a fire extinguisher, and the portable phone (telephone number 940-4475) ' ■ HEC personnel will be cognizant of all emergency telephone numbers and the location of the nearest available medical assistance. In case of any emergency, the standby observer must immediately request emergency assistance. The standby observer will instruct the third worker to contact rescue services. The standby observer must not, however, enter a confined space to rescue another worker. This is to avert ' the possibility that the cause of the first worker's crisis might still be present and prove injurious, or fatal, to the would-be rescuer. Additional rescue personnel must be brought to the scene. ' Due to the potential for complication of neck or back injuries, only trained emergency personnel ' should move an injured worker unless life-threatening conditions exist (e.g., fire, toxic gas, explosion hazard). If such conditions exist, or if the possibility of neck or back injuries can be ' absolutely ruled out, standby workers may attempt to remove the injured person with the personnel retrieval system and winch. ' Once rescue has been completed, first aid will be administered as required. ' 289A\QAPLAN2 24 Herrera Environmental Consultants,Inc.

The goal of the program is to keep dangerous waste out of the solid waste stream. Using information supplied to us by generators we issue permits to them for disposal of industrial wastes, such as sludges, sandblast waste, treated ' wood, raw materials and contaminated soils into the garbage. Primarily we use the dangerous wasta regulations for this decision. However, each of the facilities we screen waste for has other criteria we must keep in mind. We try and keep up with other options such as treatment or recycling and regularly consult with the IMEX staff. If other uses for a material exist we usually try to discuss those options with the generator.
