Download as PDF sroberts on PROD1PC70 with NOTICES Federal Register / Vol. 71, No. 132 / Tuesday, July 11, 2006 / Notices Constructed on or Before September 20, 1994. ICR Numbers: EPA ICR Number 1847.04, OMB Control Number 2060– 0390. ICR Status: This ICR is scheduled to expire on August 30, 2006. Under OMB regulations, the Agency may continue to conduct or sponsor the collection of information while this submission is pending at OMB. An Agency may not conduct, or sponsor, and a person is not required to respond to, a request for collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA’s regulations in title 40 of the CFR, after appearing in the Federal Register when approved, are listed in 40 CFR part 9, and displayed either by publication in the Federal Register or by other appropriate means, such as on the related collection instrument or form, if applicable. The display of OMB control numbers in certain EPA regulations is consolidated in 40 CFR part 9. Abstract: The Emission Guidelines apply to all municipal waste combustion (MWC) units with a combustion capacity greater than 250 tons per day of municipal solid waste (large MWC units), if construction of the unit commenced on, or before September 20, 1994, and the unit is not covered by an Environmental Protection Agency (EPA)-approved and currently effective state or tribal plan. The Emission Guidelines require initial notifications, performance tests, and periodic reports. Owners, or operators also are required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. Owners, or operators subject to these regulations are required maintain records of measurements and reports for at least five years. Burden Statement: The annual public reporting and recordkeeping burden for this collection of information is estimated to average 1,701 hours per response. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose, or provide information to, or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and VerDate Aug<31>2005 16:49 Jul 10, 2006 Jkt 208001 requirements which have subsequently changed; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit, or otherwise disclose the information. Respondents/Affected Entities: Large Municipal Waste Combustors. Estimated Number of Respondents: 9. Frequency of Response: Initially, semiannually, annually, and on occasion. Estimated Total Annual Hour Burden: 38,417. Estimated Total Annual Cost: $384,000, includes $384,000 annualized O&M costs and $0 capital costs. Changes in the Estimates: There is a decrease of 650 hours in the total estimated burden currently identified in the OMB Inventory of Approved ICR Burdens. The decrease in burden from the most recently approved ICR is due to an adjustment. In the previous ICR, the number of MWCs (i.e., sources) was reported rather than the number of respondents. The costs associated with O&M also decreased slightly due to the decrease in the number of respondents. Dated: June 29, 2006. Richard T. Westlund, Acting Director, Collection Strategies Division.

ACTION: Notice; funding availability. AGENCY: SUMMARY: The U.S. Environmental Protection Agency (USEPA) Great Lakes National Program Office (GLNPO) is requesting proposals for projects, for up to $29,600,000, addressing contaminated sediment problems in Great Lakes Areas of Concern located wholly or partially in the United States (U.S. AOCs) as outlined in the Great Lakes Legacy Act of 2002 (the Legacy Act). The deadline for all Project proposals is 5 p.m. Central Time, September 15, 2006. ADDRESSES: U.S. EPA Great Lakes National Program Office (G–17J), 77 W. Jackson Blvd. Chicago, IL 60604. FOR FURTHER INFORMATION CONTACT: Marc Tuchman, 312–353–1369/ tuchman.marc@epa.gov. DATES: The Request for Projects (RFP) is available on the Internet at https://www.epa.gov/ glla. The purpose of this request is to solicit project proposals that would help to implement the Great Lakes Legacy Act. In order to receive funding under the Legacy Act, projects must be located in one of the 31 U.S. Great Lakes AOCs. Top priority will be given to projects that (1) Constitute remedial action for contaminated sediment; (2) have been identified in a Remedial Action Plan and are ready to be implemented; (3) use an innovative approach, technology, or technique that may provide greater environmental benefits, or equivalent environmental benefits at a reduced cost; or (4) included remediation to be commenced not later than one year after the date of receipt of funds for the project. Remediation projects would include, but are not limited to, remedial options such as: dredging, capping, monitored natural recovery, treatment technologies, or a combination of remedial alternatives for contaminated sediment. The next priority level would be given to projects that seek to monitor or evaluate contaminated sediment or prevent further or renewed contamination of sediment. These projects could include: site characterizations, site assessments, source identification/source control, SUPPLEMENTARY INFORMATION: PO 00000 Frm 00067 Fmt 4703 Sfmt 4703 39115 monitoring, risk assessments, remedial alternatives evaluations and short-term/ long-term effects analyses. The Legacy Act program is not a grant program, and it is not an enforcement or regulatory program. The process for the selection of Legacy Act projects is not a grants competition, but it is based on the development of a negotiated Project Agreement (PA) between USEPA and the non-federal sponsor. USEPA will consider projects based on the extent to which they meet the requirements of the Legacy Act and the RFP. The non-federal share of the cost of a project shall be at least 35% of the total project costs in those cases where no responsible parties are clearly identified; when the non-federal sponsor is a responsible party, USEPA will require a substantially higher contribution (minimum of 40–50%). The non-federal sponsor is also responsible for 100% of cost of operation and maintenance of the project. The non-federal share may include the value of in-kind services contributed by the non-federal sponsor, and may include funds or in-kind services provided pursuant to an administrative order on consent or a judicial consent decree. The non-federal share of the cost of a project may not include any funds paid pursuant to, or the value of any in-kind service performed under, a unilateral administrative order or court order. GLNPO will review Legacy Act project proposals as they are received. GLNPO intends to enter into PA discussions with project applicants that meet the required components outlined in the RFP, and receive a high score (per the Legacy Act Rule), subject to the availability of funds. Projects that result in a PA will be funded with FY06 funds to the extent they are available. Other projects that result in a PA will be dependent upon funding, if any, received for the Legacy Act in FY07. Refer to ‘‘Final Rule: Implementation of the Great Lakes Legacy Act of 2002’’ at https://www.epa.gov/glla/rule/ for more detailed information on EPA’s process for identification, evaluation, selection, and implementation of projects for funding under the Legacy Act. Funding (through project agreements) is available pursuant to section 118(c) of the Federal Water Pollution Control Act (33 U.S.C. 1268(c)). States, tribes, industry, non-governmental organizations, and other stakeholders are eligible to apply. E:\FR\FM\11JYN1.SGM 11JYN1

    IRIS is a database that contains scientific Agency positions on 
potential adverse human health effects that may result from chronic (or 
lifetime) exposure to specific chemical substances found in the 
environment. The database (available on the Internet at https://
www.epa.gov/iris) contains qualitative and quantitative health effects 
information for more than 500 chemical substances that may be used to 
support the first two steps (hazard identification and dose-response 
evaluation) of the risk assessment process. When supported by available
