EPA ISSUES FINAL RULE ON RADIONUCLIDES IN DRINKING WATER
On December 7, 2001, EPA published a final rule (65 FR 76708) in the Federal Register establishing maximum contaminant levels goals, maximum contaminant levels (MCL)s, and monitoring, reporting and public notification requirements for radionuclides in community drinking water systems under the National Primary Drinking Water regulation. The final rule includes:
EPA is retaining the current MCL for combined radium-226/-228, the gross alpha particle radioactivity, and the beta particle and photon radioactivity in the final rule; however, the Agency intends to review the beta particle and photon radioactivity in the near future to further evaluate the various risk management issues. The final rule is applicable to community water systems, either privately or publicly owned, that provide water to an average of at least 25 people year-round or provide water for human consumption to at least 15 service connections. The final rule will become effective December 8, 2003. Wayne Toebe with Compliance Field Services is currently reviewing the final rule to determine how it will impact Hanford.

EPA OPENS A 90-DAY PUBLIC COMMENT PERIOD ON THE OPERATING PERMIT PROGRAM
On December 11, 2000, EPA published a notice (65 FR 77376) in the Federal Register announcing that a 90-day comment period had begun for the public to identify deficiencies in State and local agency operating permit programs under Title V of the Clean Air Act (CAA). EPA is taking this action as a result of litigation with the Sierra Club and the New York Public Interest Research Group (NYPIRG). The Sierra Club and NYPIRG is challenging EPA in the District of Columbia Circuit Court of Appeals over the Agency's recent extension, until December 1, 2001, of the interim approval period for 86 operating permit programs. These two groups have raised concerns that many State and local programs, with either interim or full approval, have program deficiencies and/or implementation problems. In order to address these concerns, EPA has opened the public comment period.
EPA has indicated in the public comment notice that the public can comment on deficiencies they see in either the substance of the approved program or in how a permitting authority is implementing its program. After reviewing the comments, EPA will issue a notice of deficiency (NOD) discussing the shortcomings in an operating permit program and include a timeframe for correcting the deficiency. By law the deficiencies must be corrected within 2 years. For deficiencies that EPA does not agree with, the Agency will publish a notice explaining its reasons for not making a finding of deficiency. EPA will be publishing NODs for deficiencies identified for programs that have not been granted full approval as of December 11, 2000, as well as alleged deficiencies that EPA does not agree with by December 1, 2001. For the programs that have been granted full approval as of December 11, 2000, EPA will publish NODs by April 1, 2002, along with the deficiencies they do not agree with.

EPA DEFERS PHASE IV STANDARDS FOR PCB'S AS A CONSTITUENT SUBJECT TO TREATMENT IN SOIL
On December 26, 2000, EPA published a final rule (65 FR 81373) in the Federal Register temporarily deferring a portion of the Land Disposal Restrictions (LDR) rule applicable to constituents subject to treatment (CST) in soils contaminated with certain characteristic hazardous wastes. In particular, EPA is temporarily deferring the requirement that polychlorinated biphenyls (PCBs) be treated as a CST in toxicity characteristic (TC) soils containing metals. EPA is taking this action since generators have complained that the requirement is discouraging them from cleaning up PCB contaminated soils primarily because combustion technology that is often necessary to treat the waste is expensive or not available. Generators have also commented to EPA that there is limited effective non-combustion treatment available for PCBs and a lack of State authorization to implement the amended soil standards, thus causing PCBs to be retained as a CST without the option of treating them to 10 times the Universal Treatment Standards or 90 percent reduction from the initial concentration. Because of these concerns, EPA feels it's appropriate to temporarily defer the PCB requirements while it investigates how to integrate RCRA LDR PCB cleanup standards with CERCLA cleanups, RCRA corrective actions or closures, and the Toxic Substances Control Act (TSCA) requirements.
EPA will continue to require generators to treat metal-contaminated soils to meet LDR standards for all hazardous constituents except PCBs. Also, RCRA addresses PCBs in soil under the California List provision (Section 3004(d)(2)(E)) which prohibits land disposal of hazardous wastes that contain halogenated organic compounds at concentrations equal to or exceeding 1000 parts per million (ppm). In absence of the Phase IV PCB standards, the 1000 ppm statutory level would be the upper bound of PCBs that could be in contaminated soils without triggering LDR treatment requirements. The temporary deferral will only affect soils exhibiting the TC for metals and containing PCBs in concentrations between 100 ppm and a maximum of 1000 ppm. The final rule became effective December 26, 2000. Wayne Toebe with Compliance Field Services is currently evaluating how this final rule impacts Hanford.

Ecology will be holding various workshops throughout the state to discuss the Surface Water Quality Standards amendments, the new proposed Water Rights Administration rule and management of dangerous wastes. The workshops will be held as follows:
