| Objectives | 1 October 2003, and applied for renewal of a permit to discharge waste from the Dunsmuir
Railyard under the National Pollutant Discharge Elimination System (NPDES).
The facility property (State Board Equalization Map No. 872-47-1A, parcel 1) is owned by the
Discharger. The facility lies in the Upper Sacramento Hydrologic Unit, HSA No. 525.21, as
depicted on interagency maps prepared by the Department of Water Resources. The Discharger
operates a groundwater extraction and treatment system for the removal of petroleum
contamination. A maximum of 0.86 mgd (600 gpm) of treated wastewater is discharged to a
subsurface infiltration gallery (Discharge 001) constructed in river gravels and fill immediately
adjacent to the Sacramento River, a water of the United States.
of this Order.
The site was previously owned and operated by Southern Pacific Transportation Company
(SPTC) and was purchased by the Discharger in August 1996. The discharge was previously
regulated under Waste Discharge Requirements Order No. 99-021, adopted by the Board on
30 April 1999.
The Dunsmuir Railyard is underlain by an undetermined quantity of fuel oil which has spilled or
leaked from steam and diesel locomotives, storage tanks, and conveyance pipelines since the
early 1900s. This oil flows along with groundwater, and if it not intercepted, discharges into the
Sacramento River. SPTC installed a subsurface oil/water collection system and treatment system
which was subsequently upgraded and is currently operated by the Discharger. |
