Chemical Leaman Tank Lines

Tonawanda

Former chemical tank-truck terminal and cleaning property on Fillmore Avenue. The active Class 2 State Superfund site covers roughly 15 acres and is subject to an environmental easement, making it an important companion to the River Road chemical and transportation corridor.

The documented story

What happened here?

Chemical Leaman Tank Lines operated a chemical tank-truck terminal on Fillmore Avenue in Tonawanda. Tank cleaning and freight handling generated wastewater and residues that were managed in on-site impoundments before modern hazardous-waste controls were established.

The property also contains layers of transportation and disposal history. A former trolley grade crossed the land, construction and demolition fill covered much of the western portion, and the southern edge drains toward Ellicott Creek.

Layered landscape

Transportation history preceded the chemical terminal

A trolley grade crossed the property before terminal development. During the 1970s, construction and demolition material accumulated over the western area, adding a fill history distinct from chemical-tank operations.

Tank-terminal era

Washing freight tanks concentrated chemical residues

Tank cleaning and chemical handling generated wastewater placed in on-site impoundments. Investigators also evaluated leachate and movement toward low ground and Ellicott Creek.

1987-present

Impoundment closure removed material but did not finish the site

DEC ordered closure; contaminated material was excavated and shipped off site during 1987-1989 work. Remaining soil, groundwater, fill, and migration questions keep the property in the Class 2 program under an easement.

Chronology

Timeline

  1. Pre-terminal landscape

    A north-south trolley grade crossed the property before later industrial filling and terminal development.

  2. Tank-terminal era

    Chemical Leaman operated tank-truck handling and cleaning facilities with waste impoundments.

  3. 1970s

    Construction and demolition fill accumulated on the western property, including material reportedly associated with a burned Tonawanda department store.

  4. 1987–1989

    DEC ordered closure of the impoundments; contaminated material was excavated and shipped off site, followed by additional excavation and backfilling.

  5. Present

    The Class 2 site remains under remediation requirements and an approximately 15-acre environmental easement.

Environmental record

Documented impacts

  • Tank washing and chemical-freight operations generated residues and wastewater managed in on-site impoundments.
  • Investigators documented fill, leachate breakout, and potential migration toward the low southern portion of the property and Ellicott Creek.
  • Construction and demolition debris complicates the site history but should not automatically be described as hazardous industrial waste without supporting records.

Response

Cleanup and controls

  • Waste-impoundment material was excavated and transported to an industrial disposal facility during closure work.
  • Additional investigation and remedy requirements address remaining soil, groundwater, fill, and migration pathways.
  • An environmental easement controls land use and requires compliance with the approved site-management framework.

Then and now

The site today

Chemical Leaman remains a managed Class 2 cleanup property. Its story connects chemical transportation, tank cleaning, informal fill, historic transit infrastructure, and Ellicott Creek rather than representing a single isolated spill.
