 Environmental Specialist, Port of Seattle                 2000 to 2004

Developed the construction support program for the multibillion-dollar Capital Improvement Program at Seattle Tacoma International Airport (STIA).  This program was designed to save hundreds of thousands of dollars by minimizing construction slow downs while ensuring proper soil disposal and environmental compliance.  Major accomplishments include:

  • Write and develop construction specifications jointly with Construction Mangers to ensure construction and environmental needs are addressed while minimizing costs. The new specifications saved more than $300,000 on the first major project in 2003 with similar savings realized on the six remaining 2003 contracts.
  • Assess environmental requirements and disposal issues to determine suitable solutions on a project-by-project basis. As an example, the South Terminal Expansion Project moved 2,000 cubic yards of soil per night.  Successfully identified a soil disposal facility that not only accepted this significant volume of soil at night, but also provided analysis of soil at the facility to ensure the best price for disposal.
  • Coordinate a 24-hour 7-day a week field team that effectively supports multiple overlapping construction projects. To date, the team has supported over 50 projects at STIA.
  • Designed a mapping and reporting workflow that moved data from the field to the Port’s internal data management system. This system produces reports and weekly maps that provide information on construction progress and contamination found.

Regional Supervisor, Environmental /Engineering, Tesoro , Seattle, WA   1997 – 2000

Held a corporate position that crossed multiple Tesoro Companies.  Managed Tesoro’s third party liabilities and soil and groundwater clean-ups.  Successfully achieved compliance for Tesoro’s West Coast terminals. Major accomplishments included:

  • Coordinated Tesoro’s internal resources to maintain compliance with environmental laws, legal agreements, and local regulations at its West Coast terminals. Compliance issues included stormwater, hazardous waste, air, and legal requirements.  Developed a compliance-tracking database that identified compliance issues buried in various documents.  A calendar-based system enabled full compliance despite a complicated array of documents and regulations.
  • Completed plans that took each remediation site to closure. These plans achieved cost effective, environmental compliant solutions.  Soil and groundwater cleanup at Tesoro’s prior owned properties represented a liability to the company with potential lawsuits and bad publicity. By identifying closure scenarios for each site, the most cost effective and environmentally compliant solution was designed.  This methodology enabled agencies to acknowledge progress toward negotiated goals and to satisfy their reporting needs for clean ups that spanned many years.
