Adequacy of Arizona Municipal Solid Waste Landfill Permit Program
Notice Of Public Hearing And Continued Opportunity To Comment.
The Environmental Protection Agency Region IX will hold a public hearing concerning the agency's tentative determination to approve a modification to Arizona'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. EPA published its tentative determination on February 22, 2011 and offered an opportunity for a public hearing. Initially, EPA closed its comment period on April 25, 2011 and announced it would not hold a public hearing. Since that time, in response to public interest and updates to Arizona's RD&D permit program, EPA decided to hold a public hearing, extend the comment period through the date of the public hearing, and make available for public review the updated information submitted by Arizona in support of its RD&D program.

I. General Information Back to Top
On March 22, 2004, EPA issued a final rule amending the municipal solid waste landfill criteria at 40 CFR 258.4 to allow for Research, Development, and Demonstration (RD) 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 EPA-approved State permit program to issue a time-limited RD 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 the liner. The rule also allows the Director of an EPA-approved State permit program to issue a time-limited RD permit 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 permit cannot exceed three years and a renewal of an RD permit cannot exceed three years. Although multiple renewals of an RD permit can be issued, the total term for an RD permit including renewals cannot exceed twelve years.
RD permits are only available in states with EPA-approved MSWLF permit programs that have been modified to incorporate the RD permit authority. Although a state is not required to seek approval for the RD permit provision, a state must obtain EPA approval before it may issue such a permit. Requirements for EPA's determination of a state program's adequacy and the approval procedures are contained in 40 CFR Part 239.
In 1994, EPA Region IX approved the State of Arizona's municipal solid waste landfill (MSWLF) permit program pursuant to Subtitle D of the federal Resource Conservation and Recovery Act (RCRA). By application dated June 28, 2010, updated on January 26, 2011 and September 27, 2012, the State of Arizona is seeking EPA approval for a modification to the State's existing MSWLF permit program to include RD permits. On February 22, 2011, EPA published a tentative approval of Arizona's RD permit program modification. (76 FR 9772).
Following the close of the public hearing and the public comment period, and after consideration of comments received, EPA will issue a final determination. If EPA grants approval, Arizona 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. The approval of the program modification will allow the Director of Arizona's 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 health 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 the adequacy of Arizona's RD&D modification to its MSWLF permit program.
B. Submitting Comments on EPA's Tentative Determination
Tips for Preparing Your Comments. When submitting comments, remember to:
- Identify the rulemaking by docket number and other identifying information (subject heading, Federal Register date and page number).
- Follow directions—The agency may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number.
- Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.
- Describe any assumptions and provide any technical information and/or data that you used.
- If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.
- Provide specific examples to illustrate your concerns, and suggest alternatives.
- Explain your views as clearly as possible, avoiding the use of profanity or personal threats.
- Make sure to submit your comments by the comment period deadline identified.
Submitting Confidential Business Information (CBI). Do not submit this information to EPA through www.regulations.gov or email. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as CBI and then identify electronically within the disk or CD ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR Part 2.
Docket Copying Costs. Copying arrangements will be made through the Docket facility and billed directly to the recipient. Copying costs may be waived depending on the total number of pages copied.
