J.4 WASTEWATER MANAGEMENT STANDARDS
The federal Clean iVaterAct oj1977 (CWA) cefltrels re ^tttlatas discharges of pollutants to
surface waters. The '
173-216 establishes requirements for discharges to waters of the state through the soil column to
ensure that applicable surface water quality standards are met and that beneficial uses of
groundwater are preserved. WAC 173-218 establishes requirements for injection of fluids to the
ground through wells.
J.4.1 Full Removal and Disposal Alternative (Alternative 1)
Wastewater management standards may apply to contaminated wastewaters generated as a result
of decontamination activities under the full removal and disposal alternative. Potentially
contaminated may be discharged to the ground or may
need to be collected and taken to the 200 Area's Liquid Effluent Retention Facility for treatment
at the Effluent Treatment Facility. If any surface contamination removal work is identified for
structures or waste, carbon dioxide blasting or scarifying will be used for its removal instead of
water. No wastewater would be discharged to an injection well under this alternative.
J.4.2 Containment Alternatives (Alternatives 3, 4, and 6)
Decontamination wastewaters will be managed as described for Alternative 1. Stormwater
runoff may require collection in some type of percolation/evaporation basin during operation,
closure, and post-closure of the 221-U Facility under any of these alternatives if contaminated.
Uncontaminated stormwater will not be rcouire collection and will he discharged to the ground
The percolation/evaporation basin would be expected to meet standards for waste discharges
from stormwater runoff. All known available and reasonable technologies will be implemented
in the form of stormwater runon/runotl'management controls. For example, the barrier final
design needs to address limiting runoff erosion of the barrier and capture of the runoff in some
type of percolation/evaporation basin. No wastewater would be discharged to an injection well
under this alternative.
J-5 STANDARDS FOR PROTECTION OF THE COLUMBIA RIVER
FROM DIRECT DISCHARGES
The National Pollutant Discharge Elimination System (NPDES) authority, codified in 40 CFR
122, addresses technology-based limitations and standards, control of toxic pollutants, and
monitoring for direct discharges to waters of the United States, including stormwater. Public
