10 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 Kakoi 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 30 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 November 2013

11 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.

12 2.0 SITE DESCRIPTION The Kakoi Baseyard is located in the southern portion of Oahu and is occupied by the following HDOT Highways Maintenance Crews and shops: Bridge Crew Honolulu Crew (Landscape Maintenance) Motor Pool o Heavy Motor Pool o Light Motor Pool o Small Engine Shop o Welding Shop Structures Crew Signs and Marking Crew District Warehouse Except for limited portions of landscaped areas, the entire site is paved. The HDOT Highways Oahu District Office Administration Building is located in the northwest portion of the property with a Fuel Station located to the east of the building. The Maintenance Building is located along the southwestern portion of the property and the Sign Shop and Marking Crew Storage Area are located in the southwestern corner. The District Warehouse is located along the southern portion of the property and the Honolulu Crew (Landscape Maintenance) occupies the southeastern corner of the baseyard. The Heavy Motor Pool is located in the western portion of the property, and the Light Motor Pool is located in the central portion of the property. Shops and maintenance crews use the baseyard store equipment and materials to support the various HDOT Highways Maintenance operations. The Motor Pool repairs vehicles and equipment and also operates the Small Engine Shop and the Welding Shop. With the exception of refueling of vehicles and equipment all significant maintenance operations and activities occur under cover or indoors. The baseyard does not maintain raw material stockpiles or perform any vehicle or equipment washing; these activities are conducted at the nearby Keehi Baseyard. Access to the site is provided by a driveway located at the north end of Kakoi Street. There are two storm drain inlets located near the northwest and southwest corners of the Warehouse building. Two additional storm drain inlets are located in the northeastern portion of the employee parking lot. The paved areas are primarily used for parking and storage of vehicles. The property is bordered on the east by Moanalua Stream (Figure 2-1). Storm Water Pollution Control Plan Page-3 November 2013

13 2.1 Site Drainage The majority of the site is graded towards the paved area in the southern portion of the property where two storm drain inlets are located. These two storm drains are connected to a drain pipe that runs along the southern border of the site and discharges to Moanalua Stream at a point located just off of the southeast corner of the baseyard. Two additional storm drain inlets are located in the parking lot in the northeastern portion of the property. These two storm drains collect runoff from the eastern portion of the site and are connected to a drain pipe that discharges to Moanalua Stream off of the northeastern corner of the baseyard (Figure 2-2). Moanalua Stream is the nearest water body to the site and it empties into the Keehi Lagoon. 2.2 Drainage Areas The Kakoi Baseyard is divided into two drainage areas (Figure 2-2). Drainage Area 1 (DA-1) is located in the northern and eastern portions of the baseyard and includes the administrative and employee parking areas as well as the fuel station and the Honolulu Crew operational area. DA-1 is bordered on the north by the facility driveway and on the east by Moanalua Stream. Drainage Area 2 (DA-2) is located on the southern and western portions of the baseyard and includes the operational and storage areas for all of the baseyard s maintenance crews and shops Drainage Area 1 The Honolulu Crew has an office trailer and small storage container located in the southeast corner of the baseyard. This area is used for storage of landscaping equipment and supplies. The Honolulu Crew also parks vehicles, trailers, and equipment in this area. There are no drain inlets in this portion of DA-1 (Figure 2-2). The Motor Pool operates fuel dispensers that are located under a canopy in the eastern portion of DA-1 (Figure 2-2). The dispensing pumps are connected to two 8,000 gallon underground storage tanks (USTs); one containing diesel and one containing gasoline. The double-walled USTs are monitored for leaks by a Veeder-Root system and are inspected annually by a private contractor. The administrative building and employee parking area occupy the remainder of DA-1. Storm water in DA-1 generally sheet flows to one of two storm drains located in the northeastern portion of the parking lot. Storm water from these inlets is routed to a drain pipe that discharges to Moanalua Stream at a point located just off of the northeastern corner of the baseyard. Potential pollutants in this drainage area include: Gasoline and diesel fuel stored in USTs at the fuel dispensing area (8,000 gallons each). Small quantities of petroleum (gasoline, motor oil, hydraulic oil), stored in either the original manufacturer s containers or containers with capacities smaller than 50-gallons, and secured within flammable storage lockers or double walled truck-mounted dispensing tanks. Storm Water Pollution Control Plan Page-4 November 2013

14 Small quantities of herbicides (Roundup ) stored in the original manufacturer s container, and secured within corrosive storage lockers in the Honolulu Crew s operational area. Minor leaks (drips) of oils and lubricants associated with vehicular traffic. Routine Runoff Generally, routine runoff from DA-1 may consist of dust and silt that may have been deposited either by the wind or from vehicular traffic. Dust and silt may affect water quality parameters such as total suspended solids and turbidity. As is expected from areas with vehicular activity and fueling operations, 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, failure of BMPs, or other emergency conditions (i.e., major equipment leaks). The grade of the fuel dispensing area is relatively flat and is designed to prevent minor spills from migrating towards other areas of the baseyard. 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: Spills and leaks from chemicals and equipment Fueling of equipment and vehicles Storage of vehicles and equipment Rubbish and litter Improper disposal of chemicals Chemical storage container failure Improper storage of chemicals (i.e. container deterioration, exposure to rain, no secondary containment) Improper storage of miscellaneous hazardous materials and solid waste debris Major equipment leaks Poor spill response management Drainage Area 2 DA-2 encompasses the majority of the baseyard s operational areas and houses the Bridge Crew, Structures Crew, Signs and Marking Crew, the District Warehouse, as well as the Light and Storm Water Pollution Control Plan Page-5 November 2013

15 Heavy Motor Pools, Small Engine Shop and Welding Shop. The Honolulu Crew also has a small storage room located in the District Warehouse. DA-2 is entirely paved and storm water runoff from this area is routed to one of two storm drain inlets that are located near the northwest and southwest corners of the District Warehouse. Storm water is then routed through a drain pipe that runs to the southeast corner of the facility and offsite where it discharges into Moanalua Stream. Bridge Crew The Bridge Crew has an office in the Maintenance Building and a storage room also located in the Maintenance Building that is used for hardware, ladders, and other material storage. A second storage room in the District Warehouse stores small equipment, aerosols, adhesives, paints, and solvents. This crew has various vehicles and equipment (dump truck and skid steer) at this baseyard. Two Reach-all bucket trucks are parked off-site at other locations. Structures Crew The Structures Crew has an office in the Maintenance Building and a storage room also located in the Maintenance Building that is used for various materials and small equipment (i.e. tampers and generators). Additionally, a storage cage is located on the eastern side of the Maintenance Building that is used for compressed gas cylinders and other dry materials. A small storage room is also located in the District Warehouse building that includes a flammable storage cabinet for storage of gasoline containers and. This crew has various vehicles at this baseyard. Signs and Marking Crew The Signs and Marking Crew has an office, the Sign Shop, and computer room in the Maintenance Building. A separate storage area for traffic marking supplies and equipment is located in the southwestern corner of the property. Fabricated signs are kept in an enclosed storage area located along the western side of the Heavy Motor Pool (Figure 2-2). These operational areas are used to make signs, store painting equipment, and store chemicals associated with painting (paints, adhesives, aerosols, mineral spirits, etc.). Multiple flammable storage cabinets and two hazardous material storage buildings are in use by the Signs and Marking Crew. The sign shop also maintains a small hazardous waste accumulation area for waste paints, solvents, and aerosols. District Warehouse The District Warehouse is located along the southern boundary of the property (Figure 2-2) and is used to store various items that include new chemicals (paints, solvents, cleaners, herbicides, mercury lamps, motor oil, transmission oil, and other lubricants) and many other dry materials and supplies. Heavy Motor Pool The Heavy Motor Pool is situated along the northwest border of the site and is responsible for repair and maintenance of vehicles and equipment that are greater than 15,000 gross vehicle weight (GVW) (Figure 2-2). All significant maintenance activities are performed within the Storm Water Pollution Control Plan Page-6 November 2013

16 building or under the cover of the vehicle maintenance bays. The interior of the building and the vehicle maintenance bays are outfitted with floor drains that are routed to a 1,500 gallon oil/water separator before being discharged to the City and County s sanitary sewer system. The Heavy Motor Pool facility stores various chemicals associated with automotive repair such as petroleum lubricants, solvent cleaners, brake fluid, antifreeze, etc. The facility also has a service truck that dispenses and/or stores hydraulic oil, motor oil, antifreeze, and used oil. This truck parks under cover of the Heavy Motor Pool facility when it is not in use. Used oil generated at the Heavy Motor Pool is stored in a 600-gallon capacity used oil UST located near the northeastern corner of the Light Motor Pool. The oil level in the tank is measured periodically and the used oil is pumped out by a private contractor when capacity is reached. The UST is equipped with an annular leak detection monitoring system and is managed by the Light Motor Pool. Light Motor Pool The Light Motor Pool is situated directly to the east of the Heavy Motor Pool facility and is responsible for repair and maintenance of vehicles and equipment that are less than 15,000 GVW (Figure 2-2). The Light Motor Pool facility includes a warehouse-like structure where maintenance work is performed. There are five (5) floor drains within the Light Motor Pool facility that are routed to an oil/water separator located on the southeast corner of the building before being discharged to the City and County s sewer system. The Light Motor Pool facility stores various chemicals associated with automotive repair such as petroleum lubricants, solvent cleaners, brake fluid, antifreeze, etc. Used oil generated by Light Motor Pool operations is stored in the same 600-gallon UST described above. In addition, Light Motor Pool manages the Fuel Station that is used to refuel HDOT Highways vehicles. The Fuel Station is serviced by two 8,000 gallon USTs; one containing diesel and one containing gasoline. As previously described, the double-walled USTs are monitored for leaks via a Veeder-Root monitoring system and are inspected annually by a private contractor. Small Engine Shop The Small Engine Shop is located in a room on the north side of the Heavy Motor Pool and stores miscellaneous lubricants, aerosols, and solvents in a flammable storage locker (Figure 2-2). Welding Shop The Welding Shop is located on the eastern corner of the Maintenance Building (Figure 2-2). All welding is done under cover in the shop. Small quantities of aerosols and lubricants are stored in a flammable storage locker in the Welding Shop. Compressed gases are also stored in this area. Storm Water Pollution Control Plan Page-7 November 2013

17 Honolulu Crew Storage Area The Honolulu Crew has a small storage room in the District Warehouse that is used to store weed eaters, lawn mowers, and small quantities of chemicals such as 2-cycle oil, herbicide, and gasoline. Potential pollutants in this drainage area include: Used oil stored in a 600-gallon UST located at the Light Motor Pool. Small quantities of petroleum (gasoline, motor oil, hydraulic oil), stored in either the original manufacturer s containers or containers with capacities 55-gallons or smaller, and secured within flammable storage lockers, double walled truck-mounted dispensing tanks, or on containment pallets in the motor pool areas. Small quantities of petroleum products from equipment and vehicles in the parking lot. Minor leaks (drips) of oils and lubricants associated with vehicular traffic. Routine Runoff Generally, routine runoff from the facility may consist of dust and silt that may have been deposited either by the wind or from vehicular traffic. Dust and silt may affect water quality parameters such as total suspended solids and turbidity. As is expected from areas with vehicular activity and equipment maintenance, potential for minor amounts of petroleum to enter runoff also exists. Non-Routine Runoff Non-routine runoff may be a result of failure of BMPs, or other emergency conditions (i.e., major equipment leaks). 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) Improper disposal of chemicals Storage of vehicles and equipment Storm Water Pollution Control Plan Page-8 November 2013

54 4.0 SPILL PREVENTION AND RESPONSE Spills of materials used and stored at the Kakoi 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. The Spill Response Documentation Form provided in Table 4-3 should be used to document spills and associated response action for releases in excess of the reportable quantity threshold (25 gallons or more). Copies of completed Spill Response Documentation Forms shall be kept in the Kakoi Baseyard SWPCP binder and with the District EMS Head. The Kakoi Baseyard Supervisors are responsible for implementing the Spill Prevention and Response Plan. Note these guidelines should be implemented for spills within the baseyard area as well as those that occur during maintenance work on the state highways. Storm Water Pollution Control Plan Page-45 November 2013

55 1 Stop work. TABLE 4-1: SPILL RESPONSE PROCEDURE SPILL RESPONSE PROCEDURE 2 Assess the situation: Source of Release (Stop the source of the spill, if it can be done safely) Notify Others. Call 911 if an emergency situation occurs. Inform the Baseyard Supervisors of all spills. Type of Material Spilled and Associated Hazards. If the material is flammable, ensure that all sources of ignition are removed (i.e. turn off vehicles, prohibit smoking, evacuate unnecessary personnel). Location of Release (i.e. HDOT right of way? pavement vs. soil?). Total Amount and Rate of Release. Potential for Surface Water Impacts. Deploy BMPs to protect storm drains and other surface water bodies. 3 Can the spill be cleaned up with baseyard staff and supplies? If yes continue to Step 4. If no skip to Step Assign personnel to clean the spill and don appropriate personal protective equipment. 5 Remove any incompatible materials from the area. This may include prohibiting smoking and the starting of vehicle engines. 6 Begin spill clean-up efforts by ensuring that the source of the spill has been stopped. This may include closing valves, repairing equipment, or plugging holes. 7 Confine the spill perimeter using absorbent material such as clay granules, sand, and/or soil.

70 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, Kakoi 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 Kakoi 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 each 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 30 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 Kakoi 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 November 2013 Kakoi Baseyard Version 1.0

71 2.0 MONITORING LOCATIONS 2.1 Storm Water Sample Collection Locations The Kakoi Baseyard has two drainage areas (DAs) that each have a single sampling location. Sample point KB-1, located in DA-1, is the storm drain inlet located in the parking area just northeast of the Fuel Station. Sample point KB-2, located in DA-2, is the storm drain inlet located off of the southwest corner of the District Warehouse (Figure 2-1). Sample point KB-1 was selected because it receives storm water runoff from the area that would potentially be impacted by fueling operations at the Fuel Station and it would also receive contaminants from vehicular traffic in the parking area. Storm water sampled from KB-1 is considered representative of the entire drainage area. Sample point KB-2 was selected because virtually all storm water runoff from DA-2 is discharged through this sample location. 2.2 Visual Inspection Locations 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 points KB-1 and KB-2 at the time of sample collection (Figure 2-1). Storm water discharged from the baseyard enters Moanalua Stream from two drain pipes; one pipe discharges from the northeastern portion of the baseyard and the second discharges from the southeast corner of the baseyard. Inspection of the receiving water will be conducted from these two discharge points; from these inspection locations any impacts from the baseyard s storm water discharge will be visible.

73 3.0 MONITORING PARAMETERS 3.1 Visual Inspection Visual inspections of the storm water runoff, the receiving state waters, 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. Storm water leaving the Kakoi Baseyard is discharged directly to Moanalua Stream through two drain pipes; one pipe discharges from the northeastern portion of the baseyard and the second discharges from the southeast corner of the baseyard. The Moanalua Stream empties into Keehi Lagoon. Storm water discharge and the receiving water 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.

75 4.0 SAMPLE COLLECTION PREPARATION Storm water sample collection at the Kakoi 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.

76 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 November 2013 Kakoi Baseyard Version 1.0

77 (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 November 2013 Kakoi Baseyard Version 1.0

78 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.

80 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.
