Land Disposal Restrictions: Notice of Intent to Grant a Site-Specific Treatment Variance to Dupont Environmental Treatment-Chambers Works Wastewater Treatment Plant, Deepwater, New Jersey

Короткий зміст

The Environmental Protection Agency (EPA or Agency) is proposing to grant a site-specific treatment variance from the Land Disposal Restrictions (LDR) standards for wastewater treatment sludge generated at the Dupont Environmental Treatment (DET)--Chambers Works Wastewater Treatment Plant located in Deepwater, New Jersey. This sludge is derived from the treatment of multiple listed, including K088, and characteristic hazardous waste. DET requests this treatment variance because they contend that the chemical properties of the sludge differ significantly from the waste used to establish the LDR treatment standard for arsenic in K088 nonwastewaters. Accordingly, we propose to grant an alternate treatment standard of 5.0 mg/L Toxicity Characteristic Leaching Procedure (TCLP) for the arsenic in the wastewater treatment sludge generated at this facility. If promulgated, DET may then dispose of their wastewater treatment sludge in their on-site RCRA Subtitle C landfill provided the sludge complies with the specified alternate treatment standard for arsenic in K088 nonwastewaters and meets all other applicable LDR treatment standards.
