CORE Environmental Consultants, Inc. was selected by the Village of Malverne to provide full engineering design and permitting services for the replacement of the existing fueling infrastructure at its Department of Public Works facility. The project involved the removal of aging underground storage tanks (USTs) and the installation of two new 4,000-gallon double-wall fiberglass tanks—one for diesel and one for gasoline—along with a modern, code-compliant dispensing system.
Subsurface Investigation and Site Evaluation
CORE initiated the project with a geotechnical evaluation, advancing four (4) soil borings to bedrock depth. This investigation was used to assess subsurface soil conditions and confirm suitability for UST installation. CORE provided full boring logs and lithology descriptions to inform excavation and foundation planning for the new tanks.
“CORE guided our village from site evaluation through permitting and installation with precision and responsiveness. Their work modernized our fuel systems safely and efficiently.”
Engineering Design and Technical Specifications
Once the final tank location was selected, CORE developed detailed UST Engineering and Design Plans, including:
- Demolition of two existing 4,000-gallon USTs and associated piping
- Removal of dispensers and existing fuel island infrastructure
- Design for two new 4,000-gallon double-wall fiberglass USTs (diesel and gasoline)
- Submersible turbine pumps and new dispensers
- Underground double-wall piping and sumps
- Fire suppression and leak/level monitoring systems
- Full technical bid specifications for contractor procurement
Permitting and Regulatory Coordination
CORE led the permitting process, preparing and submitting engineering drawings to the Nassau County Department of Health, Nassau County Fire Marshal, and the Village of Malverne. The design met all applicable federal, state, and local fire code and environmental standards for fuel system installations.
Construction Oversight and As-Built Documentation
During construction, CORE conducted periodic site inspections to ensure the installation followed approved plans and best practices. Upon project completion in February 2018, CORE delivered sealed as-built drawings for the Village’s permanent records.
