Phase1 - Environmental Site Assessment
Report



 
 


5.4.2


Heckett Multiserve (SCU 23)

 
 

Located at the northeastern end of the Sydney Steel Plant property, this parcel of land is located adjacent to the former Mobile Department yard (Section 5.4.3), and the Ferry Street Entrance (Figure 5-1). The parcel is also located approximately 20 metres from Muggah Creek.

The area was a water lot associated with Muggah Creek prior to 1914, was infilled between 1914 and 1939, and remained vacant until the 1960s. Since then, the parcel has primarily been used by SYSCO for product and equipment storage. Heckett Multiserve conducts slag recovery operations in the northwestern portion of the steel plant site. Heckett uses SCU 23 for vehicle storage and maintenance, as well as administration space.

In the same area, Atlantic Industrial Cleaners (AIC) formerly used the southern section of this parcel for the storage of vacuum trucks. AIC is an industrial waste management company involved in the removal and disposal of contaminated wastewater and sludges. AIC and their associated facilities are no longer at the site. Areas of debris storage and surface staining were noted in this area.

The majority of open space in this area is covered with granular materials. Slopes at certain locations show signs of surface erosion. Overland drainage in the area may present the possibility of siltation and sediment impacts to receiving waters.


 
  Potential Environmental Issues  
 

Potential environmental issues associated with the existing building and structures include asbestos containing material, lubricants, lead-based paint, PCB-containing equipment, ozone-depleting substances, mercury-containing equipment and lighting, and petroleum and chemical storage.

Potential environmental issues related to soil and groundwater consist of petroleum hydrocarbons, heavy metal, and solvent impacts as a result of historic on-site activities, as well as possible infiltration of Tar Ponds contamination such as heavy metals, PAHs, PCBs, and HNCs. Coal tar-impacted sediment may lie beneath the fill used to create that land .

Blast furnace slag was widely used as a fill material in this area. Various heavy metals are known to be present in blast furnace slag, but often in a highly immobile state. An important part of future environmental testing at this site will be the appropriate evaluation of heavy metal impacts in relations to their environmental risk.
