Introduction This Applicable Monitoring and Assessment Plan (AMAP) has been written to accompany the Section 401 Water Quality Certification (WQC) application for the proposed replacement of the existing Royal Hawaiian Groin (Figure 1) in the nearshore waters off Waikīkī Beach (herein referred to as “Project”). This AMAP has been prepared in accordance with Hawai‘i Department of Health water quality regulations promulgated in Hawai‘i Administrative Rules (HAR) Chapter 11-54 (HDOH, 2014), AMAP Guidelines (HDOH, 2015) and guidance from the General Monitoring Guideline for Section 401 Water Quality Certification Projects (HDOH, 2000). The nearshore waters of Māmala Bay off Waikīkī are designated as Class A coastal, marine waters in Hawai‘i water quality standards (HDOH, 2014). It is the objective of Class A waters that their use for recreational purposes and aesthetic enjoyment be protected. Other uses are permitted so long as they are compatible with the protection and propagation of fish, shellfish, and wildlife, and with recreation. Class A waters are not to act as receiving waters for any discharge which has not received the best treatment or control practicable. Waters in the area of the proposed Project (Fig. 1 - Royal-Moana Beach, Geocode H1898947), are included on the HDOH 2018 list of impaired waters in Hawai‘iprepared under Clean Water Act §303(d) (HDOH, 2018)for nitrate+nitrite, ammonia, turbidity, and chlorophyll α. These nearshore waters

are listed as a “Category 2” water body, meaning some uses are attained; in this case, total nitrogen, total phosphorus, and Entercocci bacteria. The Project area is also listed as a “Category 5” water body, meaning that “[a]vailable data and/or information indicate that at least one or more designated use is not being supported or is threatened, and a Total Maximum Daily Load Study (TMDL) is needed. The TMDL has been assigned a priority of low. This AMAP describes the monitoring requirements and data quality objectives to be met during water quality monitoring for the WQC. The intent of the AMAP is to monitor potential water quality impacts caused by construction of the new Royal Hawaiian Groin. The AMAP includes baseline (preconstruction), during construction, and postconstruction monitoring. Data collected as part of the AMAP will be used to assess the adequacy of best management practices (BMPs) applied during construction and will facilitate assessing potential impacts of the Project on nearshore coastal waters.

Project Description The existing Royal Hawaiian groin, located on Waikīkī Beach between the Waikīkī Sheraton and the Royal Hawaiian hotels, is in an extremely deteriorated condition. Its failure would result in the destabilization and loss of 1,730 ft of sandy shoreline located to the east of the groin. The Department of Land and Natural Resources (DLNR) proposes to replace the existing Royal Hawaiian groin with a stable, engineered groin. The objective of the proposed project is to maintain the beach so that it can provide its intended recreational and aesthetic benefits, facilitate lateral access along the shore, and provide a first line of defense to the backshore in the event of storm wave attack. The existing coastal processes, including the chronic loss of sand and beach recession, are expected to continue. However, the groin would be designed so as to maintain up to the approximate beach width of the 2012 Waikīkī Beach Maintenance shoreline nourishment project, assuming that sufficient sand was available. No enlargement of the beach beyond the 2012 nourishment project shoreline is proposed.

Figure 2. Plan view of the proposed Royal Hawaiian Groin improvements.



The new groin will be constructed along the alignment of the existing groin, and would incorporate a portion of the existing groin as a core wall to prevent sand movement through the groin. The new groin will be of rock rubblemound construction, and incorporate a cast-in-place concrete crest cap. The groin would extend 125 ft from the seawall fronting the Waikiki Sheraton hotel, and then dog-leg to the east to create a 50-ft long L-head, for a total length (along the crest) of 175 ft. The groin would be constructed of a single layer of keyed and fit 3,200 to 5,400 lb armor stone over 300 to 600 lb under layer stone and 30 to 100 lb core stone. Following stone placement, a 5-foot wide by 3-5-foot thick concrete crest cap will be constructed to stabilize the crest, and provide a foundation should a future increase in crest elevation be necessary to accommodate sea level rise. The concrete crest cap elevation would be +9 feet MSL for its first 40 ft, then transition down to +6 ft on a 1V:8H slope, then remain at +6 ft for the remainder of its length. The stone crest elevation would be +7 ft for the first 40 ft and then transition down to +4 ft for the remainder of the groin length. The existing concrete block groin would be reduced in elevation to a maximum elevation of +4 to +1 ft to facilitate construction of the new groin. Approximately 40 linear feet of the existing groin, beginning at about 120 ft from shore, will be removed as necessary to construct the dog-leg turn and transition to the L-head portion of the groin. The remaining existing groin, seaward of the new groin head, will remain in place. The +9 ft nearshore stem elevation, which is 2 ft above the present beach crest, would permit a 2 ft increase in the beach elevation in the future to accommodate near term sea level rise. However, no increase in beach elevation or width is currently proposed. The design water level for the new groin includes a 1.5 ft-factor for future sea level rise. This is equivalent to the recent NOAA (2017) Intermediate/Intermediate-High scenario for the year 2050, the approximate mid-point of the groins estimated useful life. The concrete crest cap will provide a stable foundation for an increase in the groin stem elevation should it be desired in the future. The increase in elevation could be accomplished by a precast or cast-in-place concrete wall.

Data Quality Objectives and Criteria for Measurement Data

Data quality objectives (DQOs) are qualitative and quantitative statements developed through a seven-step process based on United States Environmental



Protection Agency (USEPA) guidance for developing DQOs (USEPA, 2006) and Hawai‘i Department of Health (HDOH) AMAP Guidelines (HDOH, 2015). The Project-specific DQOs below describe each step and how it pertains to the monitoring and assessment of water quality during this Project.

Step1: State the problem Improvements to the existing Royal Hawaiian Groin will cause disturbance to nearshore waters and bottom sediments resulting in increased turbidity and possible effects to pH in the nearshore waters of the Project area. Best Management Practices (BMPs) to prevent impacts to surrounding waters will include silt containment devices (turbidity curtain) completely surrounding in-water work areas and silt fences on the ocean side of land work sites. Data are needed for the turbidity and pH to ensure BMPs are preventing impacts on nearshore waters adjacent to the work area. Temperature, dissolved oxygen and salinity will also be monitored and these parameters provide insight into environmental factors influencing water quality at the Project site. Microbiological monitoring of Enterococcus bacteria will also be implemented to ensure ocean waters adjacent to the Project are safe for recreational use. Step 2: Identify the goal of the study The goals of this study are to: (1) determine that the BMPs for the Project are adequate to ensure compliance with conditions specified in this AMAP; (2) promptly determine if BMPs are inadequate so that modification of the BMPS can be implemented in a timely manner to bring the activity into compliance; and (3) serve as a basis for self-compliance, so that activities associated with the proposed action can proceed within the parameters required by Hawai‘i water quality standards and the decision rules of this AMAP. Water quality data will be collected from a decision unit (DU) representing conditions adjacent to the work area and from two nearby control DUs, representing areas unaffected by construction work. Data will be collected before construction begins to establish baseline (preconstruction) conditions in the Project area. During construction the Project will be monitored three times per week to confirm the effectiveness of BMPs. Postconstruction monitoring will be implemented once per week for three weeks following the completion of all Project work to ensure long term adverse effects to water quality have not occurred. Monitoring of Enterococcus bacteria will be conducted weekly from a single sample location throughout pre- during- and post construction monitoring.



Step 3: Identify information inputs Monitoring Water quality data will be collected by MULTI-INCREMENT ®1 (MI) sampling or by monitoring sonde deployment during preconstruction, construction, and postconstruction monitoring. The Impact DU will be located 3 ft (1 m) outside of the turbidity curtain and surround the Project work area. The Impact DU will be monitored in triplicate during all phases of monitoring. The two control DUs (“East Control” and “West Control”) will be located 50 ft (15 m) away and surround the Impact DU, with only a single sample (or data set) collected for each control DU. Monitoring Frequency Prior to construction operations, data will be collected daily (Monday through Friday) over a period of two weeks (or at less frequent intervals if there is more time) at the impact and control DUs for a total of 10 monitoring events to establish representative baseline conditions for all measured parameters. Preconstruction monitoring results are important for establishing baseline conditions, action levels and for comparison to construction and postconstruction results to determine potential short and long-term Project impacts to nearshore waters in the work area. Data will be collected from each DU three times per week during ongoing construction work. Project operations will require 60 to 90 days to complete (Sea Engineering, 2016b). Proposed modifications to the schedule and/or BMPs are subject to acceptance by HDOH-CWB. Postconstruction, data will be collected from all three DUs once per week for three weeks when the Project work is completed and all BMPs have been removed. Monitoring of Enterococcus bacteria will be conducted weekly from a single sample location throughout pre- during- and post construction monitoring. Parameters to be monitored Potential Project impacts to water quality include short-term increases in suspended particulates and possible effects to pH. These potential impacts will be monitored by assessing turbidity and pH in the Project DUs. Temperature, salinity, and DO will also be monitored to evaluate environmental conditions at

the Project site. Total suspended solids (TSS) will not be monitored as no state standard exists for coastal waters and data are not available in time to make timely decisions on BMP effectiveness. Enterococcus bacteria will be monitored to ensure the Project work doesnnot increase bacterial load in the water column adjacent to the Project site. MI Sampling The MI sampler will be a 1-L or 2-L high density polyethylene (HDPE) bottle with two holes in the lid attached to the end of a sampling pole. The holes allow the sample bottle to fill slowly across the entire DU. The following protocol will be followed when collecting a MI sample from each DU:

1. Collect samples beginning at downcurrent control DU to reduce contamination from suspension of sediments by field technicians.

2. Tighten sampler lid to the unit’s specified alignment. Typical lid hole alignments are parallel or perpendicular to sampling pole.

3. While traversing the entire length of each DU at a constant speed, lower the sampler to just above the bottom, then raise to just below the water's surface at a pace manageable for the duration it takes for the sampler to fill.

4. Monitor the lid of the bottle throughout the DU to verify air bubbles are exiting the bottle.

5. Sample the DU at a pace that will result in monitoring the entire DU in the time it takes the sampler to fill or use clean bucket or cooler to composite multiple MI samples. Fill rates can also be altered by changing the hole size in the lid or changing the size of the bottle.

6. Remove sampler from water. 7. Measure temperature, salinity, DO and pH in the MI sampler or from a 1 L

aliquot. 8. Shake sampler well to distribute any settled sediment within the sampler

and pour off sample for turbidity (≥ 250 ml) into appropriate sample bottle.

9. Construction samples will be collected only when work operations are actually occurring; i.e., when the potential for impacts is greatest.

Sonde Deployment Alternatively, a monitoring sonde with temperature, salinity, DO, pH and turbidity probes will be deployed throughout the decision unit. If another device is used, HDOH-CWB will be notified prior to use. The sonde will be set to measure all parameters once per second. The sonde will be moved at a constant speed throughout the DU for at least five minutes and ten seconds to collect a minimum of 300 data points (see calculation in Step 5).



Enterococcus Sampling Enterococcus samples will be collected once per week from a single location in the Impact DU. Grab samples will collected from just below the water’s surface using a sterilized bottle. Narrative of site conditions Field technicians will record notes on Project activity, unusual site conditions, and condition of any treatment device or facility at the time of sample collection. Field technicians will perform visual inspections and record these observations in a field notebook or log book per Standard Methods 20th Edition 1060B specifications (SM, 2012). Observations will include date, time, water depth, and weather conditions. Field technicians will provide a description of Project activity, condition of BMPs, and any other observed activities, related or unrelated to the Project, which may affect water quality and/or beneficial uses. Photographs of each DU and areas of potential and actual disturbance will be taken. Field technicians will record a descriptive narrative of what is being documented for each photograph. Photographs will include a date (DD/MM/YY) and time stamp (24 hour clock) or that information included in the photo description. A photograph orientation map will be included with each submittal to the HDOH-CWB, depicting the location and direction of each photograph. Step 4: Define the boundaries of the study Data collection will be limited both spatially and temporally. Temporally, water quality data collection will be limited to three monitoring phases, extending from two weeks or more (depending on frequency of preconstruction monitoring) prior to actual construction to three weeks after the end of construction Project operations are expected to last 60 to 90 days. Monitoring is anticipated to extend a period of 13 to 17 weeks. Spatially, the AMAP monitoring will be restricted to 50 ft (15 m) from the Project work area. This will result in monitoring a segment of Waikīkī coastal waters extending approximately 250 ft (76 m)offshore from the shoreline and stretching a length of about 205 ft (63 m) along the shoreline. Monitoring Locations The Impact DU will extend alongside 3 ft (1 m) away from the silt curtains. The Impact DU will extend the entire length of the silt curtain (Figure 3). Control DUs will be located 50 ft (15 m) east and west of the Impact DU (see Table 1 for



coordinates). Additionally, if a plume is observed emanating from the Project site, that plume will be sampled as a separate DU (Plume DU). Enterococcus samples will be collected from the east side of the Impact DU (Figure 3) beyond the beach toe and swash zone, typically about 3 m (10 ft) from the shoreline.

Step 5: Develop the analytical approach Data collection may implement the deployment of a monitoring sonde (YSI ProDSS) with temperature, pH, salinity, dissolved oxygen, and turbidity probes. The sonde will be towed through the decision unit while being lifted and lowered through the water column. The method is essentially incremental sampling of data rather than water, however it does not have volumetric limitations associated with water sample collection of large DUs. Using the estimated size of decision units (see Table 1, above), a basic statistical analysis of the DUs using a 95% confidence level (Z-score 1.96)and a confidence interval (margin of error) of ±5 indicates a minimum sample size of 264, 243 and 288 data points are required for the Control West, Control East and Impact DU, respectively. This assumes the population of each DU is (represented by one data point for each 1ft2 segment of water) equal to the square footage of the DU using the average depth in the DUs (3 ft). To simplify sampling methodology, a minimum of 300 data points will be collected in each DU. A statistical summary for each DU will be included in each water quality submittal (ten preconstruction sampling events, three times per week during construction, and three post construction) to HDOH-CWB. All raw data points will available upon request.

Decision Rules If any of the following are noted during construction operations, a determination must be made as to the exact nature of the deviation and its probable cause (i.e., attributable or not to Project activity): turbidity at the Impact DU exceeds either of these numerical references:

• the highest mean preconstruction Impact DU value2; or • both control DUs

2 Highest mean value of triplicate samples reported in the preconstruction monitoring report and included in data report sheets to be submitted to HDOH-CWB.



pH at Impact DU:

• deviates more than 0.5 units from the control DUs; or • deviates more than 0.5 units from preconstruction range;

If a turbid plume is observed emanating from the Project site then Project work should cease until the cause of the plume is identified and BMPs corrected to contain the sediment plume. Action levels for turbidity will be established and recorded on field data sheets, so that field technicians will know when an exceedance has occurred. If field technicians notice action level deviations in the field, they will notify the contractor’s representative. The field technician and representative will attempt to track the cause of the deviation. Data collected from the Impact DU and control DUs, plus observations from the field technicians, will be used in the investigation to aid in determining if a Project activity is impacting water quality. If it is determined that Project activities are causing the water quality impact, then the activity responsible will cease until the problem is corrected or BMPs are adjusted to achieve compliance. HDOH-CWB will be notified within 24 hours or the next business day. If Enterococcus bacteria as measured from within the Impact DU exceeds the Statistical Threshold Value (STV) of 130 (cfu or MPN) per 100 ml then:

• monitoring for Enterococcus will continue daily until levels return to less than 130 (cfu or MPN) per 100 ml; and

• a warning sign will be installed and remain in place near the shoreline adjacent to the Project until results return to less than 130 (cfu or MPN) per 100 ml.

Step 6: Specify performance or acceptance criteria Some uncertainty exists in making decisions concerning water quality impacts as a result of sample design, measurement errors, or simply environmental variability. When examining impact vs. control (or pre-vs. during) data sets, a decision must be made whether the comparison shows water quality to be within the range of ambient conditions (pre- or during construction control DU data sets) or if the water quality is statistically different (that is, there was an impact, presumably from Project activities). To address monitoring/environmental variability, triplicate samples (or data sets for sonde deployment) will be collected during all phases (pre- during- post construction) at the Impact DU and relative standard deviations (RSD) calculated. If the relative standard deviation (RSD) is greater than 20% for the samples



collected in triplicate at DU Impact, then the field technicians will investigate the reason for the large difference and make changes in the monitoring protocol, if necessary. Instrument Calibration All instrument calibration procedures will be undertaken prior to field measurements. Meter calibration procedures are outlined in the manufacturer instructions and standard operating procedures (SOPs) specifically written for the meters to be used (AECOS, Inc. 2010; HACH 2008; Hanna Instruments, 2005; YSI, 2006; YSI, 2014). Operation and calibration will only be performed by personnel who have been properly trained in these procedures. Documentation of calibration and any maintenance information will be maintained in appropriate field or log books. All calibrations will be made prior to analyzing the samples and secondary checks will be made prior to and at the completion of each monitoring event. If turbidity analysis is conducted by HACH 2100Q, prior to and after turbidity analysis, Gelex standards, formazin standard and a deionized water blank will be analyzed and noted in the Project field notes to be within an acceptable range (+/-10% of standard values). The ProDSS turbidity probe, if used, will be checked in two known standards (typically 0 and 12.4 ntu) before and after monitoring. If the probe is not reading within +/-10% of the 12.4 ntu standard then the meter will be recalibrated. Calibration of the pH meter or probe is required daily to known standards (pH 7 and 10). Secondary checks will be conducted before and after analysis of samples to ensure the meter is reading correctly. Any field equipment that has been shown by calibration or otherwise to be defective, will be taken out of service until it has been repaired. The equipment will be placed back in service only after verifying by calibration that the equipment performs satisfactorily. Quality Assurance and Quality Control Protocols Field technicians will document the analytical procedures used and any relevant Quality Assurance/Quality Control (QA/QC) and instrument calibration information pertaining to specific analyses. All analytical results and field notes will be entered into a notebook or file established for this purpose. This file, including relevant QA/QC results, will be retained in laboratory records up to 5 years and will be available for inspection by HDOH-CWB-authorized personnel during normal business hours.



Step 7: Develop the plan for obtaining data The monitoring locations and frequency (described above) were developed in accordance with water quality regulations promulgated in Hawai‘i Administrative Rules (HAR) Chapter 11-54 (HDOH, 2014), General Monitoring Guideline for Section 401 Water Quality Certification Projects (HDOH, 2000), and AMAP Guidelines (HDOH, 2015). Personnel This AMAP is written using AECOS protocols and personnel. Another monitoring entity and/or laboratory may be used, after notifying HDOH-CWB and obtaining acceptance of the applicable modifications to this AMAP. Table 5 provides the names or titles, responsibilities and qualifications of the personnel involved with this monitoring plan. Water quality monitoring and field testing will be performed by AECOS field technicians experienced in water quality monitoring in streams and coastal waters of Hawai‘i. AECOS field technicians are “qualified samplers3”, experienced in, and thoroughly knowledgeable of, all aspects of the monitoring including all equipment, instruments, SOPs, calibrations, secondary checks, limits, and reporting requirements. AECOS field technicians are trained to recognize potential problems and impacts and to notify appropriate contractor personnel promptly of any problems. Chain of Custody Once data and samples have been obtained and site conditions and field measurements have been properly documented in the field notebook, a written record of the chain of custody of the data/samples must be made. A chain of custody (COC) form (Appendix A) will be filled out and accompany data/samples. The form will identify the data/samples by DU name, so the analytical results can be reported correctly. When transferring possession of data, the field technician will sign and record the date and time on the COC record. Each person who takes custody will fill in the appropriate section of the COC record. A sample data submittal sheet is shown in Appendix B.

3 According to HDOH-CWB, a “qualified sampler” is a person who actively practices environmental science, or has formal training in sampling theory, practices, and techniques. “Qualified samplers” must be thoroughly knowledgeable of all aspects of the sampling in this AMAP, including all equipment, instruments, SOPs, calibrations, secondary checks, limits, and reporting requirements.

Upon completion of the monitoring program, AECOS will retain the original data and field notebook for a minimum of five years. This monitoring program may be modified based on analysis of data, visual observations, changes in Project activities, changes in environmental conditions, and other information that may become available. Optimization of the design, if necessary, will improve monitoring and assessment of construction impacts on nearshore marine waters. All changes to the monitoring program must be accepted by HDOH-CWB prior to implementation.
