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 Windward 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 semiannually 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 October 2016

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 Windward Baseyard is located on the windward side of Oahu at Pookela Street, Kaneohe, Hawaii (Figure 2-1). The baseyard is utilized as a staging area for landscape maintenance operations and minor repair activities by multi-skilled workers (MSW) on HDOT roadways on the eastern portion of the island of Oahu. The MSW repairs may include masonry, carpentry, signs and markings, potholes, guardrails, crash attenuators, chain link fence, and graffiti removal. Access to the baseyard is available through an access gate on the northeast end of the property that connects to Pookela Street. The baseyard is entirely paved except for landscaped areas along the southern, eastern, and western boundaries of the facility. 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, as well as concrete barricades on the northern end of the facility. An administration building and vehicle shed are located on the southeastern end of the site, and two enclosed storage units are located within the paved area of the facility; a hazardous material storage container is located just north of the vehicle shed, and a Conex shipping container is used to store equipment in the center of the western side of the parking lot. The baseyard is outfitted with a wash rack that serves as a vehicle and equipment washing location for vehicles and small equipment. The wash water is captured in a sump and is subsequently processed in an oil/water separator 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 The site is graded towards the center of the property, including the landscaped areas, where storm drain inlets are located. There are four storm drain inlets in the center portion of the paved area and one storm drain inlet in the grassy swale near the eastern boundary (Figure 2-1). The drain inlets are interconnected and flow by gravity to the northernmost inlet within the baseyard. This last inlet is connected to the storm drain system on Pookela Street. There is a drain pipe that discharges runoff from the HWY-O Kaneohe Field Office property into the Windward Baseyard property at the southeast corner behind the Administration Building. This flow drains via a grassy swale to the storm drain inlet behind the Vehicle Shed. Additionally there is a curb cut drain inlet located along Banyan Drive on the west edge of the facility that collects runoff from the roadway leading to the State Hospital. Flow from this drain inlet connects into the baseyard storm drain system. The nearest water body is the Kapunahala Stream, which is located approximately 1,600 feet to the east of the facility, across Kahekili Highway. Kapunahala Stream feeds into Kaneohe Stream which empties into the Pacific Ocean. 2.2 Drainage Areas The Windward Baseyard is divided into two drainage areas (Figure 2-2). Drainage Area 1 (DA-1) is located in the southeastern corner of the baseyard and includes the vegetated areas Storm Water Pollution Control Plan Page-3 October 2016

10 surrounding the wash rack, vehicle shed and administrative buildings. Drainage Area 2 (DA-2) makes up the remainder of the baseyard and includes the paved areas of the facility Drainage Area 1 DA-1 includes the Administration Building, the wash rack, the vehicle storage shed, and the vegetated area to the east of these structures. DA-1 receives significant run-on from the adjacent HWY-O Kaneohe Field Office property located south of the baseyard. Storm water in this area flows from south to north in a prominent drainage swale and discharges into storm drain located just south of the parking area. As indicated in Figure 2-2, all storm water from the vegetated areas flow to the storm drain before being routed to the interconnected storm drain that runs down the center of the facility parking lot. Potential pollutants in this drainage area include: 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. Small quantities of herbicides (Roundup ) stored in the original manufacturer s container, and secured within corrosive storage lockers in the vehicle shed. 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. 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 be a result of spillage, leaks, fuel dispensing, routine maintenance operations, overflow from the wash rack, failure of BMPs, or other emergency conditions (i.e., major equipment leaks). The grade of the facility is such that spills in the operational portions of the vehicle shed and surrounding paved areas would migrate towards the center of the parking lot (DA-2). However, there is still the potential for spilled materials to impact DA-1. Potential non-routine runoff may result from the following sources: Spills and leaks from chemicals and equipment Fueling of equipment (e.g. topping off motor oil, fueling of weed eaters and mowers) Equipment washing resulting in overflow Storm Water Pollution Control Plan Page-4 October 2016

11 Facility washing Rubbish and litter Improper disposal of chemicals Application and use of chemicals Major equipment leaks Poor spill response management Such incidents will be addressed immediately as described in the Spill Prevention and Response Plan (see Section 4.0) Drainage Area 2 DA-2 encompasses the entirety of the baseyard s paved area and includes equipment and vehicle parking, enclosed equipment and hazardous material storage containers, outdoor bulk material storage, and a concrete barricade storage area. As indicated in Figure 2-2, storm water in DA-2 flows from south to north and from the sides of the parking lot towards the center of the parking lot. Storm water then enters one of four storm drain inlets located along the center of the parking lot. Potential pollutants in this drainage area include: Small quantities of petroleum (gasoline, motor oil, hydraulic oil), stored in the original manufacturer s containers or in containers with capacities smaller than 5-gallons, and secured within flammable storage lockers in the vehicle shed or the hazardous material storage container. Small quantities of herbicides (Roundup ) stored in the original manufacturer s container and secured within corrosive storage lockers in the vehicle shed. 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. Metals from equipment parking and outdoor material storage areas (vehicles, equipment, guardrails, signposts, and metal culverts). Gravel, dirt, concrete, and other aggregate materials stored in the outdoor bulk material storage area and concrete barricade storage area. Small quantities of petroleum products from equipment and vehicles in the parking lot. Storm Water Pollution Control Plan Page-5 October 2016

12 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. 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, overflow from the wash rack, 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: Fueling of equipment (e.g. topping off motor oil, fueling of weed eaters and mowers) Equipment washing Facility washing Rubbish and litter Improper disposal of chemicals Hazardous material storage container failure Improper storage of chemicals (i.e. container deterioration, exposure to rain, no secondary containment) Improper storage of raw materials Application and use of chemicals Major equipment leaks Poor spill response management Such incidents will be addressed immediately as described in the Spill Prevention and Response Plan (see Section 4.0).

33 4.0 SPILL PREVENTION AND RESPONSE Spills of materials used and stored at the Windward 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 Windward Baseyard SWPCP binder and with the District EMS Head. The Windward Baseyard Supervisor is 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-27 October 2016

47 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, Windward 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 Windward 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 Attachment 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 Windward Baseyard will be reviewed to determine if additional BMPs can be implemented to reduce pollutants associated with that parameter.

48 2.0 LOCATION 2.1 Storm Water Sample Collection Location The Windward Baseyard has two drainage areas (DAs) that each have a single sampling location. Sample point WW-1, located in DA-1, is the storm drain inlet located in the grassy area just off of the northeastern corner of the vehicle shed. Sample point WW-2, located in DA- 2, is the storm drain inlet east of the raw material storage area (Figure 2-1). Sample point WW-1 was selected because it receives storm water runoff from the area that would potentially be impacted by wash rack operations and it would also receive contaminants from any uncontrolled spill in or around the vehicle shed. Sample point WW-2 was selected because it receives the vast majority of storm water runoff from all of the facility s paved surfaces. It s also located directly in front of the bulk material storage areas on the east and west sides of the facility. Splitting the sample collection into these two sample points will facilitate identification of the source of any contaminants detected in the storm water samples. 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 point WW-1 and WW-2 at the time of sample collection (Figure 2-1). Because storm water from the Windward Baseyard enters a common storm water drainage system that receives discharge from a number of other properties before discharging to state waters, basic water quality criteria noted at the receiving water would not necessarily be indicative of conditions caused by baseyard operations. Therefore, rather than inspecting the state receiving water, final inspection of the storm water discharge will occur at sample points WW-1 and WW-2, which are located where discharge leaves the baseyard. Observations made at sample points WW-1 and WW-2 will be assumed to be representative of discharge conditions as received by the state waters. Storm Water Monitoring Plan Page-2 October 2016

50 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. Storm water leaving the Windward Baseyard flows by gravity through an interconnected storm drain along the center portion of the paved area to the northernmost storm drain inlet and out to the storm drain system on Pookela Street. The system discharges into Kapunahala Stream, which feeds into Kaneohe Stream, and eventually empties into the Pacific Ocean. 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.
