Environmental Protection Agency (EPA).
Notice of Tentative Determination of Adequacy and Opportunity to Comment.
The Environmental Protection Agency Region IX is proposing to approve a modification to California's municipal solid waste landfill (MSWLF) permit program to allow the State to issue research, development, and demonstration (RD&D) permits for new and existing MSWLF units and lateral expansions. The modification will allow the Director of the approved state program to provide a variance from certain MSWLF criteria, provided that the MSWLF owner/operator demonstrates that compliance with the RD&D permit will not increase risk to human heath and the environment. The Director may provide a variance from existing requirements of MSWLF criteria for run-on control systems, liquids restrictions, and final cover. EPA is seeking public comment on its tentative determination of adequacy of California's RD&D modification to its MSWLF permit program.
Comments must be received on or before August 13, 2007. EPA will hold a public hearing on August 13, 2007 in the first floor conference room of EPA Region IX, 75 Hawthorne Street, San Francisco, California, if sufficient public interest is expressed. If by August 1, 2007, EPA does not receive sufficient public interest for a public hearing, EPA may cancel the public hearing with no further notice. If you are interested in attending the public hearing, contact Karen Ueno at (415) 972-3317 to verify that a hearing will be held.

I. General Information
On March 22, 2004, EPA issued a final rule amending the municipal solid waste landfill criteria at 40 CFR 258.4 to allow for RD&D permits. (69 FR 13242). This rule allows for variances from specified criteria for a limited period of time. Specifically, the rule allows the Director of an approved State to issue a time-limited RD&D permit for a new MSWLF unit, existing MSWLF unit, or lateral expansion, for which the owner or operator proposes to use innovative and new methods which vary from either or both of the following: (1) The run-on control systems at 40 CFR 258.26, and/or (2) the liquids restrictions at 40 CFR 258.28(a), provided that the MSWLF unit has a leachate collection system designed and constructed to maintain less than a 30-cm depth of leachate on liner. The rule also allows the Director of an approved State to issue a time-limited RD&D permit for a MSWLF unit for which the owner or operator proposes to use innovative and new methods that vary from the final cover criteria at 40 CFR 258.60(a)(1) and (2), and (b)(1), provided that the owner or operator demonstrates that the alternative cover system will not contaminate groundwater or surface water, or cause leachate depth on the liner to exceed 30 cm. An RD&D permit cannot exceed three years and a renewal of an RD&D permit cannot exceed three years. Although multiple renewals of an RD&D permit can be issued, the total term for an RD&D permit including renewals cannot exceed twelve years.
RD&D permits are only available in states with approved MSWLF permit programs that have been modified to incorporate the RD&D permit authority. Although a state is not required to seek approval for the RD&D permit provision, a state must obtain EPA approval before it may issue such a permit. Requirements for state program determination of adequacy and approval procedures are contained in 40 CFR part 239.
In 1993, EPA Region IX approved the State of California's MSWLF permit program pursuant to Subtitle D of the Federal Resource Conservation and Recovery Act (RCRA). With its application, dated March 28, 2006, and revised on February 21, 2007, the State of California is seeking EPA approval for a modification to the State's existing MSWLF permit program to incorporate RD&D permits.
II. EPA's Action
A. Tentative Determination
After completing a thorough review, EPA is proposing to tentatively approve California's RD&D permit program modification. California has lawfully promulgated and fully enacted regulations for the RD&D permit program, and these regulations are adequate to ensure compliance with the federal criteria at 40 CFR 258.4. In conformance with the federal regulations, and in addition to California-specific requirements, an owner or operator is required to maintain less than a 30-cm depth of leachate on liner and demonstrate that compliance with the RD&D permit will not increase risk to human heath and the environment over compliance with a standard MSWLF permit.
Following the close of the public comment period and in consideration of comments received, EPA will issue a final determination. If approved, California will be able to issue variances for run-on control systems, liquid restrictions, and final cover criteria to allow for innovative and new methods, such as bioreactor landfills.
