NOTICE OF PUBLIC
HEARING
concerning
RENEWAL OF WASTE
DISCHARGE REQUIREMENTS
(NPDES NO. CA0085260)
For
IRONHOUSE SANITARY DISTRICT
WATER RECYCLING FACILITY
WATER RECYCLING FACILITY
CONTRA COSTA COUNTY
Ironhouse
Sanitary District is the owner and operator of the Ironhouse Sanitary District,
Water Recycling Facility (Facility), a publicly owned treatment works located
at 450 Walnut Meadows Drive, Oakley, California. The Facility provides sewerage services for
the City of Oakley, Bethel Island, and some unincorporated areas of Contra
Costa County, serving a population of approximately 38,969. The Facility provides tertiary treatment for
up to 4.3 million gallons per day (MGD). Tertiary treated wastewater from the
Facility is discharged to the San Joaquin River, a water of the United States,
within the Sacramento – San Joaquin Delta.
Discharges
from the Facility are currently regulated by Waste Discharge Requirements Order
R5‑2008‑0057, issued by the Central Valley Regional Water Quality Control Board
(Central Valley Water Board) on 25 April 2008. An Order is proposed to renew the NPDES
permit. The proposed NPDES permit renewal removes effluent limits for
settleable solids, oil and grease, aluminum, copper, fluoride, lead, total
residual chlorine, iron, manganese, and MBAS, because the upgraded Facility no
longer demonstrates reasonable potential to cause or contribute to an
exceedance of the applicable water quality objectives in the San Joaquin
River. The proposed Order also includes new
effluent limitations for methylmercury, diazinon, and chlorpyrifos. The Facility cannot immediately comply with
the new effluent limits for methylmercury, so a compliance schedule is included
in the proposed Order.
A
public hearing concerning this matter will be held during the Central Valley Water
Board meeting scheduled for:
DATE: 5/6 December 2013
TIME: 8:30 a.m.
PLACE: Central Valley Regional Water Quality Control Board Room
