"Unknown" Wastes

The 2003 RCRA operating permit, issued for Dow's current and past hazardous waste facilities, identified two ponds that were closed with "Unknown Fill Materials in Place".

This section of the website will examine the operating history of the two ponds. 

One of the ponds, the Southside (500 Bldg.) Powerhouse Cooling Pond,  was constructed in portions of recovered chemical waste ponds. 

Prior to 1957, chemical waste ponds existed on the Eastside of the C&O railroad tracks.  The ponds were bounded by H street on the north, N street on the south, the C&O tracks on the west and Saginaw Road on the east.  It is also possible that the chemical ponds extended north beyond H Street in earlier years.

In the late 1950's, these ponds were filled in and manufacturing facilities, offices, maintenance buildings and warehouses were constructed in the reclaimed pond areas. 

The second pond, also closed with "Unknown Fill Materials in Place", was the triangular pond on the west side of the river.  The pond was constructed after 1959.  This pond was used to settle solids that passed through the secondary clarifiers of the waste water treatment plant. 

Dow has indicated that the company has no information as to what type of material was used to fill in these two ponds. 

Please be patient until this section of the website is fully completed.
