FEATURED PROJECTS
Natural Resource Management and Planning
HDOT Highways - Emergency Scour Countermeasure Repairs for Kapaa and Kapue Stream Bridges - Kapaa, Kauai and
Hamaka Coast, Hawaii Island;
Following severe structural damage to the Kapaa and Kapue Bridges caused by Hurricane Lane in August 2018, KPC supported the State of Hawaii Department of Transportation (HDOT) - Highways Division in their environmental consulting and regulatory requirements. This included preparing a Pre-Construction Notification, working closely with the Army Corps of Engineers representatives, and supporting research on significant cultural and natural resources (biota and avian resource reviews). Subsequently, permitting activities such as Department of Army’s Section 404, State of Hawaii Department of Health Section 401 water quality certifications (WQC) planning and monitoring, US Fish and Wildlife Section 7, and State of Hawaii Department of Land and Natural Resources Section 106 consultations were completed. Supporting materials for these projects were completed using GIS. In the field, an in-water pollution and in-water prevention plan (IWPPP) developed by KPC was implemented and daily stormwater BMP inspections, 401 WQC sampling in the stream, Avian Biota Assessments, and Botanical Assessments were performed.
Baseline Fishery Assessment for Wake Atoll, USAF Wake Island Airfield - Wake Island;
Wake Island is a coral atoll approximately 2,300 miles west of Honolulu in the Pacific Ocean administered by the United States Air Force (USAF). The current state of the fishery at Wake Atoll is considered undeveloped and is essentially a recreational use-only resource for the inhabitants and visitors of Wake Atoll. A baseline fisheries assessment is being conducted in support of the U.S. Fish and Wildlife management goals developed for Wake Island as part of the Integrated Natural Resource Management Plan (INRMP). The purpose of the ongoing fisheries assessment is to implement multiple forms of marine fisheries surveys to support natural resource planning efforts at Wake. This and future fishery surveys are designed to provide the data needed to ensure that recreational fishing does not have adverse impacts on fish stocks and their coupled submerged lands at Wake Atoll. All information gathered during the baseline surveys including catch data, transect data, GIS data, and camera footage were analyzed to provide a quantitative assessment of the population status, conditions, and biodiversity of fishes inhabiting Wake.
Honolulu Authority for Rapid Transit – Halawa, Moanalua, and Kalihi Streams - Honolulu, Hawaii;
The Halawa Stream mouth at its confluence to Pearl Harbor and Moanalua and the Kalihi Stream mouth at Keehi Lagoon required installing cast-in-place pilings. During in-water-work, an Applicable Monitoring and Assessment Plan (AMAP) sampling program was implemented to support decision-making based on water quality and discharge of the streams. KPC assisted in daily weather monitoring to select rainfall events to establish the baseline discharges of each of the streams. KPC provided overall Environmental Permitting and Water Quality Certification Support; Prepared NPDES, AMAP, and Baseline Sampling Report.
Environmental Site Assessments and Remediation
HDOT Highways - Kolekole and Hakalau Parks Lead Assessments and Remedial Alternative Analysis - Hamakua Coast, Hawaii Island;
The KPC team supported subsurface soil investigations below two State of Hawaii Department of Transportation Highways (HDOT) - Highways Division bridge structures along the Hamakua coast (Kolekole and Hakalau). The projects addressed lead contamination in the surface and subsurface soil beneath these formerly lead-based paint-coated bridges. To expedite the opening of the park, KPC prepared Sampling and Analysis Plans and a Safety and Health Plan for both bridges. KPC then conducted sampling, prepared a Remedial Alternative Analysis, Fact Sheets, supported Public Outreach within the community, and completed a Remedial Alternative Memorandum under State of Hawaii Department of Health CERCLA guidelines. All field data collection locations were recorded using GPS and presented in reports using GIS geospatial software. These multi-year projects are still ongoing, and the focus is now primarily supporting additional soil assessments below the bridge at Hakalau Beach Park and preparing a Remedial Alternative Analysis and Record of Memorandum.
Site Remediation of Contaminated Soils - Honolulu, Hawaii;
Following the demolition of three former building structures, chlordane and lead-impacted soil was detected at levels above State of Hawaii Department of Health (HDOH) Environmental Action Levels. Following the preparation of an Exposure Hazard Management Plan (EHMP), sampling of subsurface soil, interpretation of analytical results, and decision-making regarding removal of chlordane and lead-impacted soil was carried out to support site remediation. We worked closely with the project developer team and HDOH to optimize the project construction activities to reduce the project's development and long-term environmental liabilities cost by addressing the contaminated soil. In doing so, the project included preparation of a Hazardous Building Materials and Soil Assessment Investigation, Phase I Environmental Site Investigation, Construction Exposure Hazard Management Plan (C-EHMP), additional post-demolitions sampling of surface and subsurface soil below and surrounding the buildings, soil removal remediation, and preparation of an After-the-Fact Soil Removal Action Report. Ultimately, the landowner was granted a “no further action” with an Environmental Hazard Management Plan no longer needed for this property.
Environmental Compliance
Spill Prevention and Response Plan Recertification, and Storage Container Management Plan for the United States Air Force - Republic of Korea;
KPC updated Spill Prevention and Response Plans (SPRP) and Storage Container Management Plans (SCMP) in accordance with all regulatory compliance documents for the following five Co-located Air Bases in the Republic of Korea: Suwon, Cheongju, Daegu, Gwangju, and Gimhae. In doing so, KPC provided technical support for environmental programs ensuring compliance to minimize environmental impacts related to U.S. Forces Korea activities. Correspondingly, the inventory of all 241 storage tanks for each of the five Air Bases was updated with comprehensive tank characterization and geospatial tank asset data for their GIS database. In addition to updating the SPRPs, SCMPs, and the tank database, KPC prepared a DD form 1391 for each of the five bases after the submittal of the SPRPs. The DD form 1391 was used by the Department of Defense to submit to Congress as requirements and justification in support of funding requests for military construction.
HDOT Airports, Environmental Site Assessment - Honolulu, Hawaii;
Following years of petroleum-related and Hazardous Materials Management/ Storage activities at the former Hawaiian and Aloha Airlines Cargo and Maintenance facilities, an environmental site investigation and recommendations were prepared for the State of Hawaii Department of Transportation (HDOT) - Airports Division. A background historical use assessment and a Sampling and Analysis Plan (SAP) were developed to investigate over 20 former tenant structures and former Hazardous Materials Management/Storage facilities. This included solvent systems for parts cleaning, underground storage tanks, former known release areas, transformer pads, and underground fuel/solvent delivery systems. Ultimately, the KPC team developed further investigation and remedial alternatives for the HDOT - Airports Division to support discussion with regulatory staff at the State of Hawaii Department of Health.
Yacht Harbor Towers Spill Prevention, Control and Countermeasures Plan - Honolulu, Hawaii;
The Owners Association of Yacht Harbor Towers required a new Tier I qualified Spill Prevention, Control, and Countermeasures (SPCC) Plan to aid in preventing a discharge of oil into U.S. navigable waters (Ala Wai Canal and Ala Wai Boat Harbor). In addition to the SPCC Plan, a condition assessment, maintenance recommendation summary, operation and maintenance schedule for the facility engineering staff (with a new site inspection form), and instructional inspection documentation for the aboveground storage tank and generator were all prepared.
Hazardous Waste Management Plan and Hazardous Waste Contingency Plan for the United States Marine Corps - Republic of Korea;
A Hazardous Waste Management Plan (HWMP) was developed for a Marine Corps Installation in the Republic of Korea. The HWMP provided the procedures to use in the event of fires, explosions, or any unplanned sudden or non-sudden release of chemicals, hazardous waste, or their constituents to air, soil, or surface water. Site investigations of all hazardous waste accumulation point sites and a review of available hazardous waste management documents were conducted. KPC supported the prime environmental subcontractor by processing the field data, summarizing survey observations/ findings, and providing recommendations synthesized in the HWMP document (e.g. permit compliance, environmental compliance management plan preparation, inspections, audits, etc.). All geospatial tank asset information was provided as a GIS deliverable following FED metadata requirements and a Hazardous Waste Contingency Plan for the installation was also prepared.
