CORE Environmental Consultants, Inc. was selected as the environmental design consultant under a multi-year capital improvement program managed by the NYC Department of Design and Construction (NYCDDC). The program focuses on upgrading petroleum underground storage tanks (USTs), sump systems, and associated fuel infrastructure at municipal facilities across the Bronx. CORE provides full-service environmental engineering, regulatory permitting, and investigation services across dozens of active project sites.

CORE is responsible for providing comprehensive environmental engineering, regulatory compliance support, site characterization, remedial planning, and construction-phase technical services. The program ensures full alignment with the revised federal UST regulations under 40 CFR Parts 280/281 and NYSDEC petroleum bulk storage (PBS) requirements, while modernizing critical fueling infrastructure across the city.

Multisite Site Assessments & Pre-Design Investigations

CORE conducted full-scale environmental and infrastructure assessments across dozens of active municipal sites. These investigations evaluated:

  • Existing UST sizes, types (single or double-walled), age, and compliance status
  • UDC sump performance and leak detection practices
  • Conditions of dispensers, piping, spill/overfill prevention equipment
  • Known and suspected petroleum release history

Findings from each site were compiled into site-specific Pre-Design Reports (PDRs), forming the technical basis for tank replacement or upgrade decisions, and providing cost-effective paths to eliminate the burdens of triennial testing and legacy compliance gaps.

“CORE’s technical leadership in tank design, permitting, and environmental assessments has made them an essential partner in modernizing NYC’s fuel infrastructure.”

Engineering Design for UST and Fuel Dispensing System Upgrades

CORE developed full engineering design packages for the removal, replacement, or retrofit of UST systems and fuel dispensing components. Designs addressed:

  • Upgrades to double-walled tanks and piping with interstitial monitoring
  • UDC sump replacement with integrated leak detection
  • Spill and overfill prevention system design
  • Integration with NYC Fire Code and DOB compliance requirements
  • Site access constraints and staging for active facilities

All design deliverables included stamped drawings, specifications, site plans, and permitting documentation tailored to each site’s operational needs.

Environmental Investigation & Remedial Planning

At locations with documented or suspected petroleum releases, CORE prepared and executed NYSDEC-compliant site characterization plans, including:

  • Soil and groundwater sampling during geotechnical drilling
  • Vertical and lateral delineation of contamination
  • Receptor evaluations and source area identification
  • Development of Corrective Action Plans (CAPs) and Remedial Work Plans (RWPs)

Depending on findings, CORE proposed appropriate remedial strategies including excavation, enhanced natural attenuation, long-term monitoring, or system design for in-situ treatment.

Regulatory Permitting and Multi-Agency Coordination

CORE led all permitting efforts associated with:

  • NYSDEC PBS registrations and variance requests
  • NYCDOB filings and fuel system plan reviews
  • FDNY plan approval for fuel dispensing and emergency power systems

CORE served as liaison between the project team, city agencies, and regulators to ensure timely review cycles, avoid delays, and secure all necessary approvals prior to construction.

Construction Services and Technical Support

Throughout the construction and implementation phases, CORE provides:

  • Submittal and shop drawing reviews
  • Construction oversight and periodic site visits
  • Response to RFIs and field modifications
  • Post-installation inspections and as-built drawing development
  • Closure reporting and NYSDEC notification, if remediation is required

This full lifecycle technical support ensures the successful and compliant delivery of fuel infrastructure projects across the city’s most critical operational sites.
