Environmental, Health, and Safety Risk Framework, Hawai‘i — Developed and implemented an organization-wide environmental, health, and safety (EHS) management system for the W.M. Keck Observatory, located at the summit of Maunakea.  The EHS management system was developed according to standard risk assessment and control strategies and established objective criteria for how to mitigate hazards at the facility.  The framework included a risk assessment matrix and established appropriate response and resourcing expectations for high, medium, and low risks.  Implementation included the socialization of new values and principles through engagement with internal stakeholders, both in leadership and at the staff level. Implementation of the EHS risk framework systematized EHS processes into day-to-day business activities and tangibly improved the EHS culture within the organization.

Environmental, Health, and Safety Audit, Hawai‘i — Served as project manager for a third-party audit at the W.M. Keck Observatory, for both the headquarters facility in Kamuela, Hawai‘i, and the summit facility at the summit of Maunakea.  Oversaw a comprehensive audit to document areas of noncompliance with EHS rules and regulations within the organization.  Prioritized, budgeted, and secured appropriate funding and labor to coordinate response actions for 150 findings, including engineering, design, and installation activities for infrastructure modifications; updates related to programmatic and procedural deficiencies; revisions to equipment maintenance and inspection schedules; and updates for recordkeeping and administrative processes.

Lead Soil Removal, Umauma Bridge, Hawai‘i — Oversaw and monitored lead-based paint and lead soil disturbance activities to protect workers’ health and the environment during refurbishment and reconstruction of the Umauma Bridge in North Hilo.  Responsible for ensuring workers followed protective procedures to reduce exposure and minimize lead dust generation during construction.  Performed personnel air monitoring to quantify exposure to construction workers during dust generating activities, including sanding, grinding, needle gun removal, welding, and excavation.  Performed soil testing on material excavated during construction of bridge footings, scrap metal, and other lead-coated waste material.  Characterized more than 2,208 cubic yards of lead-contaminated soil as hazardous or nonhazardous waste and oversaw the proper packaging, transport, and disposal of lead waste according to federal, state, and local regulation.

Environmental Compliance Plan, Concrete Coring Company, Hawai‘i — Developed the environmental compliance plan for a concrete coring company, and integrated procedures and requirements within the overall EHS program for the facility.  Conducted an inventory of all industrial activities and operations performed by the company on the island of Oahu.  Performed a comprehensive applicability study to identify relevant environmental regulations, summarized compliance justification and requirements for each applicable regulation, identified minimum qualification and training requirements for personnel and subcontractors, and provided a list of records that should be retained to substantiate compliance with applicable regulations at a federal, state, and local level.

Environmental Program Oversight, Bellows Air Force Station (BAFS), Waimanalo, Hawai‘i — Provided environmental consulting services to the environmental point of contact at BAFS.  Prepared the site-specific hazardous waste management plan and solid waste management plan.  Conducted a facilitywide air emissions inventory and permit applicability study.  Conducted annual UIC testing and monitoring and documented results in report format for submission to the Hawai‘i Department of Health.

Pesticide-Impacted Soil, Punahou School, Hawai‘i — Performed environmental soil sampling to establish the extent and magnitude of contamination at Punahou School during Phase 1A of the Punahou Re-development Master Plan.  Prepared a site-specific and programmatic environmental hazard management plan to establish proper identification and handling procedures for soil confirmed or suspected to contain pesticides at hazardous levels. All work was completed in accordance with the Hazard Evaluation and Emergency Response (HEER) Technical Guidance Manual.

Na‘alehu Seed Dipping Vat, Soil Remediation, Na‘alehu, Hawai‘i — Prepared and implemented the sampling and analysis plan to determine the lateral and vertical extent of fungicides, dioxins and furans, heavy metals (lead, arsenic, mercury), and organochlorine pesticides at a former seed dipping vat at the former Hutchinson Mill in the Ka‘u District.  Summarized results in the site investigation and environmental hazard evaluation report.

Ritz Carlton Soils Remediation Project, Waikiki, Hawai‘i — Authored and implemented the sampling and analysis plan to determine the lateral and vertical extent of heptachlor and heptachlor epoxide contamination at the subject property utilizing multi-incremental sampling and decision unit techniques.  Provided written guidelines for soil management during construction activities, including decontamination procedures, soil excavation and handling requirements, stockpiling and storage requirements, and soil sampling and disposal criteria.  Developed an environmental hazard management plan to establish engineering and institutional controls to manage contaminated soil in-place to support issuance of the No Further Action with Restrictions determination from the Hawai‘i Department of Health.  All work was completed in accordance with the HEER Technical Guidance Manual.

North Kohala Former Pesticide Mixing Area, Hawai‘i — Authored and implemented the sampling and analysis plan to delineate the lateral and vertical boundary of pesticide (PCP, dioxin) and heavy metals (lead, mercury, arsenic) contamination at the subject property.  Prepared an environmental hazard evaluation based on sampling results, and prepared and executed a detailed remedial action plan, including excavation, hauling, disposal, and confirmation sampling methodologies to remove contaminated soil from the subject property.  Summarized results in the remedial action report and obtained No Further Action letter from the Hawai‘i Department of Health.  All work was completed in accordance with the HEER Technical Guidance Manual.
