International Airport, Ohio

KEMRON conducted Phase I and Phase II Environmental Due Diligence Audits (EDDA) as part of this engagement for this airport client. The EDDA is required by the FAA for acquisition and disposal of real property at aviation facilities, to minimize the FAA’s environmental liabilities. KEMRON conducted the Phase I EDDA for over 400 acres of property.

The airport lies between residential and heavy industrial communities, and has been in operation for over 70 years. During the course of conducting the EDDA, KEMRON collected information from over 30 regulatory agencies and affected parties. All available historical documentation regarding site environmental issues was researched, reviewed, summarized, and catalogued. KEMRON then completed a comprehensive site reconnaissance, walking all areas encompassed by the EDDA and documenting existing site conditions and any potential environmental concerns. In addition, KEMRON was responsible for completion of all requirements pertaining to wetlands, threatened and endangered species, cultural and historic resources and biotic communities, per NEPA and DOT requirements.

Based upon this comprehensive document review and site reconnaissance, the EDDA revealed over 20 separate potential areas of environmental concern, including former USTs, hazardous waste units, solid waste disposal sites, contaminated soil management issues, and numerous potential releases of hazardous substances.

Subsequent to completion of the Phase I EDDA, KEMRON designed and implemented work plans for site investigation of environmental issues through a Phase II EDDA. KEMRON was responsible for development of the technical approach to assessment, preparing site specific health and safety plans, implementation of the plans, and report preparation. Work completed during the Phase II EDDA included installation of test pits, field screening and field testing of soil and waste materials, geoprobe investigations and extensive soil sampling and analysis for petroleum products, volatile and semivolatile contaminants. The Phase II EDDA field investigations evaluated all areas of concern identified during the Phase I.

Results of the Phase I and Phase II EDDA were compiled into a comprehensive five volume report of findings which included catalogued reference materials, original CADD mapping, analytical data, and interpretative summaries. All documents were also supplied to the client in electronic format for archival purposes.

KEMRON was contracted to perform environmental sampling of nine surface water outfalls and two instream monitoring locations to evaluate compliance with the Airport’s NPDES permit requirements. KEMRON also performed sewer sampling under the airport’s Comprehensive Sampling and Analysis Program (CSAP). KEMRON personnel responded within 12-24 hours of special requests and on regularly scheduled intervals to perform environmental sampling. The NPDES surface water sampling and analytical results were used to determine compliance with the NPDES permits.

For the airport’s CSAP sampling events, KEMRON personnel participated in identification of sewer manholes and catch basins using existing drawings of the airport sewer system. KEMRON personnel employed the drawings and field reconnaissance notes to determine appropriate sampling points, and conduct sampling within the sewer system.

Field activities are conducted both airside and landside. KEMRON personnel were available to work flexible schedules to accommodate needs for sampling events occurring during both day and night hours. Airside sampling was conducted in close coordination with airport personnel and in compliance with all FAA requirements to ensure that air traffic is not interrupted or impacted by the sampling activities, and that safety is ensured throughout each sampling event.
