7 1.0 INTRODUCTION Federal regulations administered by the State of Hawaii, Department of Health (DOH) through State of Hawaii, Department of Transportation (HDOT), Highways Division National Pollutant Discharge Elimination System (NPDES) Individual Permit No. HI S requires that municipal industrial facilities, such as the Pearl City Baseyard, comply with Hawaii Administrative Rules (HAR) 11-55, Appendix B. Those requirements include the development and implementation of a Storm Water Pollution Control Plan (SWPCP) designed to protect water quality by minimizing the discharge of pollutants in storm water runoff from industrial activities at the baseyard. 1.1 SWPCP Implementation The storm water management controls described in this plan will be implemented by HDOT, Highways Division, Oahu District (HWY-O) and an up-to-date copy of the SWPCP shall be maintained on site Training Management, staff, and maintenance personnel will be provided with training on the SWPCP initially upon implementation and at least annually thereafter. Additionally, training will be conducted following any major revision to the SWPCP and will also be provided to new hires. This training will include, a discussion of potential pollutants, best management practices (BMPs), spill response procedures, and past spills. Training records will be documented and retained for five years. Baseyard personnel will be responsible for implementing controls detailed in the SWPCP and training courses Inspections Baseyard inspections will be conducted at least quarterly to ensure that BMPs are implemented, maintained, and functioning effectively. All inspections will be documented on the Baseyard SWPCP Inspection Checklist (Appendix A) and retained in the Maximo Asset Management System (AMS) for five years. Corrective actions for deficiencies noted during inspections will be documented, tracked, and closed-out in the AMS Monitoring Storm water monitoring will be conducted at the baseyard on an annual basis as detailed in the Storm Water Monitoring Plan (Appendix B). Results will be recorded on a Discharge Monitoring Report (DMR) and submitted to the DOH no later than 60 calendar days after sample collection. DMRs, field notes, and laboratory results will be retained for five years. 1.2 SWPCP Revisions The SWPCP will be reviewed as needed to identify necessary revisions. At a minimum, the plan will be reviewed every five years. Updates may be required due to current BMP failures, spill events, changes in baseyard activities, changes in baseyard features, or other necessary changes. Re-evaluation of the SWPCP will also be conducted pursuant to inspections and related findings Storm Water Pollution Control Plan Page-1 January 2014 Pearl City Baseyard Version 3.0

8 at the facility. The District Engineer will be responsible for approving revisions to the SWPCP. For the purposes of this plan, the District Environmental Management Section (EMS) Head functions as the emergency coordinator (EC). In the event the plan is modified, a copy of the updated SWPCP will be provided to the baseyard, EC, H3 Tunnel Operations Control (TOC), and the Highways Division Environmental Engineer (HWY-CE). Additionally, HWY-O shall document and report the SWPCP changes to the DOH, Clean Water Branch (CWB), within thirty days of when the changes arise.

9 2.0 SITE DESCRIPTION The Pearl City Baseyard is located in the south central portion of Oahu, beneath the H-1 freeway in Pearl City at nd Street, Pearl City Hawaii (Figure 2-1). The Pearl City Baseyard s primary purpose is to support roadwork and landscape maintenance conducted nearby by HWY- OM and the Landscaping Unit. The Landscape Maintenance Subunit uses the baseyard to park vehicles and landscape maintenance equipment (i.e. mowers, weed eaters, bobcat loader, etc.) and to store fuels and chemicals. Flammable cabinets located inside a storage container are also used to store small quantities of herbicide, gasoline, motor oil and 2-cycle oil. Occasionally, minor equipment maintenance is conducted within the covered paved areas. Only limited equipment fueling (i.e. lawn mowers, chainsaws, etc.) is conducted on site. Vehicles are not fueled within the baseyard. The Highway Electrical, Traffic Signs and Marking, and Structures Subunits also use the baseyard, primarily for the purpose of storing supplies. Access to the baseyard is available through an unnamed access road off of Lehua Avenue. The access road connects to the baseyard driveway, which forms the southern boundary of the facility. Highway pillars serve to divide the baseyard into different service areas. From west to east, these service areas include: salvage equipment storage; Electrical Crew storage area; Signs and Markings Crew storage area; aggregate storage; employee parking and office; wash rack; dewatering area; and structures storage area. The majority of the site is situated under the cover of the freeway viaduct and groundcover generally consists of asphalt with isolated areas of exposed soil. The paved areas are used for parking and storage of vehicles and supplies. The paved area is also used to store raw materials such as gravel, sand, and asphalt. An administration building is located in the central portion of the site, and two Conex shipping containers are used to store equipment adjacent to the raw material storage. The baseyard is outfitted with a wash rack that serves as a vehicle and equipment washing location for numerous landscape and roadway maintenance vehicles and small equipment. The baseyard dewatering facility serves as a pre-treatment location for storm drain wash water derived by roadway maintenance crews. The wash water from the wash rack and liquids from the dewatering facility are processed in oil/water separators prior to being discharged into the City and County s sanitary sewer system. No wash water flows offsite or into any storm drains or natural waterways. 2.1 Site Drainage Most of the baseyard is situated under the cover of the freeway viaduct, and therefore, is not exposed to rainfall. However, storm water can flow through the property from areas located outside of the freeway viaduct overhang and from several freeway downspouts (Figure 2-1). There is one drainage headwall located outside of the baseyard area that drains all the water flowing from the baseyard to the south toward a field. Discharge to the field may percolate into the ground or be conveyed to the East Loch of Pearl Harbor. The aforementioned wash rack, which is used by numerous landscape and roadway maintenance crews to wash vehicles and equipment, is situated on the northern side of the baseyard. The wash water does not flow offsite or into any storm drains or natural water ways. Instead, it is captured in a trench drain and sump and is processed in an oil/water separator before discharging into the City and County of Honolulu s (City and County s) sanitary sewer system. Storm Water Pollution Control Plan Page-3 January 2014 Pearl City Baseyard Version 3.0

10 The nearest water body is the Waiau Stream, which is a Class 2 stream that borders the eastern edge of the facility. The Waiau Stream empties into the East Loch of Pearl Harbor, which is classified by HAR (d) as an inland estuary. 2.2 Drainage Areas The Pearl City Baseyard is divided into four drainage areas (Figure 2-2), as follows: Drainage Area 1 (DA-1) is located in the northwestern corner of the baseyard and includes the salvage equipment storage area; Drainage Area 2 (DA-2) includes the Electrical Crew and Signs and Markings Crew storage areas; and the Pearl City Baseyard Crew operational areas and Administration Building; Drainage Area 3 (DA-3) encompasses the vehicle and equipment wash rack, dewatering facility; and the Structures Crew storage area; and, Drainage Area 4 (DA-4) contains mostly open, grassy and unpaved areas, with some general storage of oversized materials Drainage Area 1 DA-1 is a centralized storage area where excess vehicles, trailers, and equipment from all HWY-O baseyards are stored while awaiting disposal. This area is unpaved and storm water enters the area from either the exposed north portion of this area or from two down spouts in the partially covered south portion. As indicated in Figure 2-2, combined storm water from open areas and down spouts either drains into the ground or flows to the southeast and discharges onto the government access road just south of the storage area. Potential pollutants in this drainage area include: Metals and small quantities of petroleum products from vehicles, trailers, and equipment parking. Routine Runoff Generally, routine runoff from this drainage area may consist of dirt, silt, and vegetation that may be carried away in storm water. These components may affect water quality parameters such as total suspended solids and turbidity and may result in floatables in storm water runoff. Non-Routine Runoff Non-routine runoff may occur due to failure to properly implement BMPs (e.g., removal of fluids and batteries from salvage equipment). Such incidents will be addressed immediately as described in the Spill Prevention and Response Plan (see Section 4.0). Potential non-routine runoff may result from the following sources: Storm Water Pollution Control Plan Page-4 January 2014 Pearl City Baseyard Version 3.0

11 Leaks from vehicles and equipment Drainage Area 2 DA-2 encompasses the Electrical Crew and Signs and Markings Crew storage areas; and the Pearl City Baseyard Crew operational areas. DA-2 is a mostly paved with some a small portion of unpaved area in the Signs and Markings Crew storage area. DA-2 is entirely covered by the freeway viaduct. The Electrical Crew storage area contains three enclosed material storage containers and outdoor bulk material storage (i.e. electrical lighting and posts). As indicated in Figure 2-2, storm water in the Electrical Crew storage area in DA-2 flows from three downspouts and from the government access road just north of this storage area. Storm water from DA-1 potentially enters into DA-2 in the Electrical Crew storage Area. The Signs and Markings Crew storage area contains bulk material storage (i.e. galvanized sign posts; traffic markers). There are two downspouts in this portion of DA-2 (Figure 2-2) in addition to storm water run-on from the government access road located north of this area. There is also a permanent storm water settling basin in this area. The Pearl City Baseyard Crew operational areas contain two enclosed material storage containers, aggregate and bulk material storage, vehicle, equipment, and employee parking, and the Administration Building. There are no downspouts in in this portion of DA-2 however storm water run-on from the government access road located north of these areas (Figure 2-2) enters into DA-2. Storm water flows through DA-2 via various drainage ditches and sheet flow (Figure 2-2) travelling from the northwest to the southeast until it crosses the cement baseyard roadway. Storm water then travels by surface grade heading east to the center of the baseyard. Storm water then exits the baseyard at the lowest point of the property and enters into a headwall and drainpipe that leads to government property. Potential pollutants in this drainage area include: Metals from material storage areas (i.e. electrical lighting components and light posts; galvanized sign posts; vehicle and equipment parking). Small quantities of petroleum (gasoline, motor oil, hydraulic oil), stored in either the original manufacturer s containers or containers with capacities smaller than 5-gallons, and secured within flammable storage lockers in the vehicle shed, or from equipment and vehicles in the parking lot. Small quantities of herbicides (Roundup ) stored in the original manufacturer s container and secured within corrosive storage lockers. Gravel, dirt, concrete, and other aggregate materials stored in the outdoor bulk material storage area. Storm Water Pollution Control Plan Page-5 January 2014 Pearl City Baseyard Version 3.0

12 Rubbish from trash receptacles Routine Runoff Generally, routine runoff from this drainage area may consist of dirt, silt, and vegetation that may be carried away in storm water. These components may affect water quality parameters such as total suspended solids and turbidity. As is expected from areas with vehicle traffic, the potential for minor amounts of petroleum to enter runoff also exists. Non-Routine Runoff Non-routine runoff may be a result of spillage, leaks, fuel dispensing, routine maintenance operations, storm water contact with materials, failure of BMPs, or other emergency conditions (i.e., major equipment leaks). However, such incidents will be addressed immediately as described in the Spill Prevention and Response Plan (see Section 4.0). Potential non-routine runoff may result from the following sources: Rubbish and litter Improper storage of materials (i.e. container deterioration, exposure to rain, no secondary containment) Poor spill response management Spills and leaks from chemicals and equipment Fueling of equipment (e.g. topping off motor oil, fueling of weed eaters and mowers) Facility washing Improper disposal of chemicals Application and use of chemicals Major equipment leaks Drainage Area 3 DA-3 includes the vehicle and equipment wash rack, which is utilized by multiple HWY-O maintenance crews, the storm water dewatering facility, which is operated and maintained by the Special Services Crew, and the Structures Crew storage area. All of these areas are paved. DA- 3 is entirely covered by the freeway viaduct. As indicated in Figure 2-2, there are three downspouts in the wash rack and dewatering areas of DA-3. The Structures Crew storage area contains outdoor bulk material storage (i.e. guardrails, crash attenuators, sand barrels) and as indicated in Figure 2-2, there are two downspouts in this area. Storm Water Pollution Control Plan Page-6 January 2014 Pearl City Baseyard Version 3.0

13 Portions of DA-3 potentially receive storm water run-on from DA-4 (Figure 2-2). Storm water flows through DA-3 via various drainage ditches and sheet flow travelling from the northeast to the southwest until it crosses the cement baseyard roadway. Storm water then travels by surface grade and drainage pipes heading east to the center of the baseyard. Storm water then exits the baseyard (with run-off from DA-2) at the lowest point of the property and enters into a headwall and drainpipe that leads to government property. Potential pollutants in this drainage area include: Biodegradable soaps, approved detergents, and wash waters associated with washing activities at the wash rack. Soaps and detergents are stored in the original manufacturer s container and are kept in the administration building. Wash waters are normally contained by the wash rack system. Sediment and other materials being processed in the dewatering facility. Metals from material storage areas (i.e. guardrails, crash attenuators). Routine Runoff Generally, routine runoff from this drainage area may consist of dust and silt that may have been deposited from wind, or from vehicular traffic. These components may affect water quality parameters such as total suspended solids and turbidity and may result in floatables in storm water runoff. As is expected from areas with vehicle traffic, the potential for minor amounts of petroleum to enter runoff also exists. Non-Routine Runoff Non-routine runoff may be a result of overflow from the wash rack or dewatering facility, storm water contact with materials, or failure of BMPs. Potential non-routine runoff may result from the following sources: Equipment washing resulting in overflow Facility washing Rubbish and litter Application and use of chemicals Poor spill response management Improper storage of materials (i.e. container deterioration, exposure to rain, no secondary containment) Such incidents will be addressed immediately as described in the Spill Prevention and Response Plan (see Section 4.0). Storm Water Pollution Control Plan Page-7 January 2014 Pearl City Baseyard Version 3.0

14 2.2.4 Drainage Area 4 Drainage Area 4 (DA-4) includes the grassy areas along the northern fence line portion of the baseyard where no storage or operational activities occur. The remaining portion of DA-4 is mostly open, unpaved areas, with some general storage of oversized materials (i.e. metal plates, galvanized culvert pipe) awaiting disposal. This portion of DA-4 is entirely covered by the freeway viaduct. As indicated in Figure 2-2, the grassy areas are directly exposed to storm water however there is no direct contact with storm water (no downspouts) in the covered and unpaved areas of DA-4. Potential run-on from the exposed grassy area of DA-4 is minimal. Minimal storm water that flows through DA-4 will sheet flow through the area (Figure 2-2) travelling from the northeast to the southwest until it crosses the cement baseyard roadway. Storm water then travels by surface grade and drainage pipes heading east to the center of the baseyard. Storm water then exits the baseyard (with run-off from DA-2) at the lowest point of the property and enters into a headwall and drainpipe that leads to government property. Potential pollutants in this drainage area include: Sediment and other materials. Metals from material storage areas storage (i.e. metal plates, galvanized culvert pipe). Routine Runoff Generally, routine runoff from this drainage area may consist of dust and silt that may have been deposited from wind, or from vehicular traffic. These components may affect water quality parameters such as total suspended solids and turbidity and may result in floatables in storm water runoff. As is expected from areas with vehicle traffic, the potential for minor amounts of petroleum to enter runoff also exists. Non-Routine Runoff Non-routine runoff may be a result of storm water contact with materials, or failure of BMPs. Potential non-routine runoff may result from the following sources: Rubbish and litter Improper storage of materials (i.e. container deterioration, exposure to rain, no secondary containment) Storm Water Pollution Control Plan Page-8 January 2014 Pearl City Baseyard Version 3.0

44 4.0 SPILL PREVENTION AND RESPONSE Spills of materials used and stored at the Pearl City Baseyard can contaminate storm water runoff. The baseyard has not had any significant leaks or spills of toxic or hazardous pollutants, nor has there been any discharge of storm water that has resulted in the discharge of a reportable quantity within the past five years. However, the guidelines outlined in the checklist below (Table 4-1) are intended to provide procedures to follow in the event a spill does occur. Table 4-2 includes a listing of pertinent contact numbers that may be necessary if a spill were to occur.

61 1.0 SCOPE AND APPLICATION This monitoring plan will describe the sampling methods and procedures to be utilized when collecting storm water samples at the State of Hawaii, Department of Transportation (HDOT), Highways Division, Pearl City Baseyard. In addition to storm water sample collection and analysis, visual inspection of storm water runoff, receiving state waters, best management practices (BMPs), and control measures will be conducted as described in Section 3.1. Storm water monitoring is required for industrial facilities, such as the Pearl City Baseyard, by the Hawaii Administrative Rules (HAR) 11-55, Appendix B and is also detailed in the Highways National Pollutant Discharge Elimination System (NPDES) Permit No. HI S Part E. 1.1 Representative Storm Event One sample should be collected from the sample collection point at least once per calendar year during a representative storm event. Visual inspection of water quality criteria should occur each time a storm water sample is collected. In accordance with HAR , a representative storm event is defined as rainfall that accumulates more than 0.1 inches of rain and occurs at least 72 hours after the previous measurable rain event of greater than 0.1 inches. The National Weather Service forecasts can be used as a planning tool for gauging storm events and the automated storm water sampler s rain gauge data will be used to verify storm event validity. 1.2 Reporting HDOT, Highways Division must report the results of sampling efforts to the Department of Health using the Discharge Monitoring Report (DMR) form in Appendix A. Results shall be reported within 60 days of sample collection. In addition to the DMR, the laboratory reporting sheets for the sample with Quality Assurance / Quality Control (QA/QC) data, flow calculations, the start and end time of the monitored storm event, and the duration between the last storm event of 0.1 inch or more shall be included in the submittal. If there was no discharge for that monitoring year, the DMR shall be completed and submitted indicating such. Completed DMRs shall be submitted to the address below and a copy will be retained for a period of five years at the HDOT, Highways Division, Oahu District (HWY-O) Office: Director of Health Clean Water Branch Environmental Management Division State Department of Health P.O. Box 3378 Honolulu, HI Violations of the effluent limitations listed in Table 3-1 or of the basic water quality criteria described in Section 3.3 must be reported in accordance with HAR Appendix B, Section 10 (c). Briefly, the violation must be orally reported to the Department of Health (DOH) Clean Water Branch as soon as the violation is identified and a written report must be provided within five days. In the event of a violation, the Storm Water Pollution Control Plan (SWPCP) for the Pearl City Baseyard will be reviewed to determine if additional BMPs can be implemented to reduce pollutants associated with that parameter. Storm Water Monitoring Plan Page-1 January 2014 Pearl City Baseyard Version 1.0

62 2.0 MONITORING LOCATIONS 2.1 Storm Water Sample Collection Location The Pearl City Baseyard has four drainage areas (DAs), two of which (DA-2 and DA-3) discharge into one sampling location, PC-1, located on the southern, central portion of the baseyard near where discharge occurs to a drainage headwall off of the property (Figure 2-1). This location was selected because the majority of the storm water from the baseyard areas sheet flows through this area prior to discharge from the site. Sample point PC-1 was selected because it receives storm water runoff from the area that would potentially be impacted by wash rack operations, the dewatering facility, and it would also receive contaminants from any uncontrolled spill in or around the vehicle, equipment, material, and bulk storage areas. 2.2 Visual Inspection Location As described in Section 3.1, visual inspection of storm water runoff, receiving state waters, BMPs, and control measures is required to ensure basic water quality criteria are not violated. Visual inspection of storm water runoff will be completed at the storm water sample point PC-1 at the time of sample collection (Figure 2-1). Because storm water from the Pearl City Baseyard discharges to a large field prior to reaching state waters, a clear inspection point at the receiving water is difficult to define. Therefore, rather than inspecting the state receiving water, final inspection of the storm water discharge will occur at sample point PC-1, which is located at the point where the discharge leaves the baseyard. Observations made at sample point PC-1 will be assumed to be representative of discharge conditions as received by the state waters. Storm Water Monitoring Plan Page-2 January 2014 Pearl City Baseyard Version 1.0

64 3.0 MONITORING PARAMETERS 3.1 Visual Inspection Visual inspections of the storm water runoff, control measures, and BMPs will be completed as part of the storm water monitoring program to detect conditions which may cause violations of the basic water quality criteria. The storm water leaving the Pearl City Baseyard flows through a headwall and is discharged to a large field located south of the property where it eventually discharges to the East Loch of the Pearl Harbor Estuary. Storm water discharge will be inspected for the following characteristics: Turbidity Color Floating oil and grease Floating debris and scum Materials that will settle Substances that will produce taste in the water or detectable off-flavor in fish Items that may be toxic or harmful to human or other life Baseyard BMPs and control measures (e.g., storm drain filters) will be inspected to identify maintenance needs, signs of failure, or opportunities for improvement. 3.2 Storm Water Analysis Storm water runoff will be sampled and tested for the parameters listed in Table 3-1 to ensure that industrial activities are not impacting the receiving water. If monitoring results indicate that the discharge limit has been equaled or exceeded, the SWPCP will be reviewed to determine if additional BMPs can be implemented to reduce pollutants associated with that parameter.

66 4.0 SAMPLE COLLECTION PREPARATION Storm water sample collection at the Pearl City Baseyard will be performed using an automated storm water sampler from Teledyne ISCO (see Section 5). Although storm water sample collection will be performed by the automated sampler, sample pickup and delivery to the laboratory will need to be performed by personnel. The automated sampler will be configured to issue a text message alert to designated staff when storm conditions are met and when sample collection has begun. Therefore, the following equipment and materials should be prepared and readily available to respond to a sampling event. The checklist provided in Appendix B may also be followed. 4.1 Equipment, Supplies, and Personal Protective Equipment TABLE 4-1: EQUIPMENT, SUPPLIES, AND PERSONNEL PROTECTIVE EQUIPMENT Water Quality Meter for ph, Field Notebook and Steel Toe Boots temperature, and D.O.

67 5.0 SAMPLING PROCEDURES This section provides an overview of the automated sampler configuration and sample collection process. 5.1 Storm Water Sample Collection Summary Storm water samples will be collected using a Teledyne ISCO automated storm water sampler with integrated rain gauge. The system will be positioned at the respective sampling location and a weir box will be constructed to facilitate storm water collection. The sampler will be outfitted with Teflon intake tubing to maintain integrity of oil and grease analysis and will be configured to commence sampling within 15 minutes of storm water runoff. The automated sampler will be configured to only commence sampling if rainfall has not exceeded 0.1 inches in the previous 72 hours. Total rainfall will be measured and automatically logged by the integrated rain gauge and the sample will only be retained if rainfall for the sampling event meets the minimum criteria of a representative storm event (0.1 inches). The automated sampler will also log critical storm event information including the start and stop times for rainfall. The automated sampler will be configured to collect the oil and grease and volatile organic compound sample aliquot immediately as a grab sample. The automated sampler will then begin collecting samples for the remaining analyses by collecting one sample during the first 15 minutes of the discharge and at 15-minute intervals thereafter for the duration of the discharge. If the discharge lasts over one hour, the sample collection will stop. If the discharge stops after only one sample has been collected the sample will be analyzed as a grab sample. If two or more samples were collected the sample shall be combined proportionally in the laboratory to make a composite sample. The automated sampler will send a text message to alert the designated personnel of the storm event and that sample collection has been initiated. The sampling personnel will travel to the baseyard to collect the samples from the automated sampler and collect the field measurements of ph, temperature, and dissolved oxygen. The ph and temperature shall be analyzed in the field as grab samples within 15 minutes of storm water discharge and will be recorded in the field logbook. Dissolved oxygen will also be measured in the field as a grab sample. See Section 5.5 for further discussion of field measurements. 5.2 Collection Time Due to the required laboratory holding times, the automated sampler will be configured to only initiate sample collection from Monday through Thursday, 11am. Consideration should also be made to ensure that samples are not collected on a day prior to a holiday. Sample collection will begin within the first 15 minutes of storm water discharge from the sample location. 5.3 Equipment Calibration Ensure that all equipment, such as the ph and temperature probe, and the dissolved oxygen meter, is calibrated prior to sampling efforts by following the manufacturer s instructions Storm Water Monitoring Plan Page-7 January 2014 Pearl City Baseyard Version 1.0

68 (Appendix C and D). Calibrate the equipment as soon as the first alert is received from the automated sampler. Appropriate calibration logs will be maintained. 5.4 Assemble Personnel and Equipment 1. Upon receiving notification from the automated sampler that sampling conditions have been met, assemble at the sampling site. 2. Record observations in the field notebook: a. Date and time of arrival onsite; b. Names of sampling personnel present; c. Time that rainfall began; and d. Other observations about the discharge such as color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, or other obvious indicators of storm water pollution. 5.5 Field Measurements The analysis for ph and temperature must be conducted within 15 minutes of sample collection. Dissolved oxygen must also be analyzed as soon as possible. Therefore, the following procedures should be followed to analyze these constituents in the field ph and Temperature 1. Fill the disposable cup with storm water from the first sample bottle (grab sample) in the automated sampler. Only use as much water as is necessary to get a reading. 2. Turn on the water quality meter and set it in the cup. 3. Immediately record the temperature in the field notebook. 4. Allow ph to stabilize (i.e. stay on a consistent number for a period of time). 5. Record the ph measurement in the field notebook Dissolved Oxygen 1. Use the storm water in the disposable cup from the ph reading. 2. Turn on the water quality meter and select the desired units of measure by pressing and holding the MODE/HOLD button until the proper units are shown in the display. 3. Remove the electrode cover and place the electrode in the sample to be measured. 4. Stir the electrode in the sample to remove any trapped air bubbles from the membrane surface. 5. Do not submerse the electrode to the point that the sample liquid reaches the meter s electrode collar. 6. Allow the meter time to settle to the final dissolved oxygen measurement value. Stabilization time can vary from 10 seconds to 5 minutes. 7. Record the dissolved oxygen value in the field notebook. Storm Water Monitoring Plan Page-8 January 2014 Pearl City Baseyard Version 1.0

69 5.6 Completing Sample Event 1. Record the time that sampling activities are completed. 2. Record the time that the rainfall stops and/or time of departure from the site. 3. Fill out the COC form (see 5.6.1). 4. Deliver to the laboratory Chain of Custody The COC is the document that must accompany any sample that is sent to a laboratory for analysis. The COC is a way to ensure the integrity of samples from the moment they are collected until they reach the laboratory for analysis. Therefore, whenever custody of the samples collected is passed to another individual, that individual must sign for receipt. The COC also details information the laboratory will use to analyze the sample. An example is provided in Figure 5-1 and blank forms will be provided by the lab.

71 6.0 HAZARDS AND PRECAUTIONS The following sections provide a summary of safety and environmental hazards or concerns. 6.1 Safety Hazards Typical safety hazards that can lead to injury and illness of personnel can include but are not limited to: General physical injury as a result of strenuous field work, which may include: o Back strains and hand injuries resulting from loading and unloading of sample coolers. o Trips and falls from uneven ground. Hazards posed by weather conditions such as flooding, lightning, and landslides. Ensure that all safety precautions are followed during the sampling activities: Ensure that full coolers are lifted by two people, if applicable. Ensure that rests are taken to prevent back injury during sample collection. Wear steel toed boots and safety vests to prevent falls and increase visibility to traffic. Place safety cones around the sampling area to divert traffic away from samplers. Ensure that all personnel wear nitrile gloves during sample collection to prevent chemical injury. Never risk the safety of the sampler to conduct a sampling event. Consult the local weather and news reports to determine whether hazardous conditions may exist such as landslides or floods. 6.2 Environmental Hazards Special care should be made to minimize the potential of contaminating storm water runoff with any materials used during sample collection.
