Download as PDF ebenthall on PRODPC60 with NOTICES 47162 Federal Register / Vol. 73, No. 157 / Wednesday, August 13, 2008 / Notices appropriated BEACH Act grant funds above the $10 million current level. EPA would implement this approach by reviewing State and Territorial spending every October 1 and adjusting the allocation to certain States and Territories on the basis of the funds that these States and Territories have not yet expended. EPA would review EPA’s Financial Database Warehouse to confirm the amount of outstanding funds reported. In making this determination, EPA will take into account those funds that have been committed through an appropriate State, Territorial or Tribal contract, interagency agreement, or similar type of binding agreement, but have not been requested for reimbursement, i.e., that are not showing as ‘‘drawn down’’ in EPA’s Data Warehouse. As noted in section III.F., EPA recognizes that States and Territories have different financial management systems and that those systems could result in delayed billing to EPA, even though the States and Territories might have already expended funds to monitor beaches and notify the public. EPA also recognizes that States and Territories typically spend the previous year’s grant award in any given beach season due to the timing of the availability of BEACH Act grants in the middle of the beach season. Therefore, to account for these factors, EPA is considering an approach that would reduce the new grant award by the amount of unexpended grant funds that are more than three years old. For the 2010 beach season, EPA would review State and Territory spending in October 2009 and determine how much grant funding from fiscal years 2001 to 2007 is still unspent by each State and Territory. EPA would identify the unspent amounts from 2001 through 2007 in the Financial Database Warehouse and compare them to the amount EPA expects to award in fiscal year 2010. EPA would then reduce the 2010 grant award for those States and Territories with unobligated funds from 2001 through 2007 by the amount remaining. For example, in 2010, consider a State that normally receives $250,000 annually yet has $100,000 remaining from grants awarded up to fiscal year 2007. Under the approach that EPA is considering, EPA would reduce the State’s grant award for the following year’s beach season by $100,000 (the amount the State has left unspent from fiscal years up to 2007), thus resulting in an award of $150,000 in 2010. The $100,000 not awarded to the State would be combined with unused grant funds from other States and Territories and re-allocated among the States and VerDate Aug<31>2005 15:38 Aug 12, 2008 Jkt 214001 Territories that have fully used their funds from fiscal years up to 2007 using a modified allocation formula, described below. EPA is considering reallocating these additional funds according to a second, modified allocation formula composed of only two factors—beach miles and beach use—to only those States and Territories that do not have remaining money older than three years old. EPA is working with States and Territories to obtain sufficient information to base a supplemental allocation formula on those two factors. As discussed in Section III.B.2.a, with the help of State and Territorial beach program managers, EPA is compiling and quality testing beach mile information for all the BEACH Act States and Territories and expects to have reliable beach mile data on the extent of beaches by mid-2009. EPA is also working with the National Oceanic and Atmospheric Administration to expand its research on beach use to Great Lakes States, and is also looking for information on beach use in the Territories. EPA will work with States to ensure effective implementation of the new allocation formula. B. Why Isn’t EPA Amending Other Parts of the Allocation Formula? EPA is considering the retention of the use of the surrogates EPA has used for beach mileage and beach use—i.e., shoreline miles and coastal population—as factors of the current allocation formula for the first $10 million in BEACH Act grant funds. As discussed in section III.D, States consider their current level of BEACH Act funding to be the financial foundation for their beach monitoring and notification programs. Because this funding has been relatively stable over the last six years, States and Territories rely on these funds to provide them a generally consistent level of funding for their programs. For many States, funds for recreational water monitoring are limited to the amount received in BEACH Act grant funding. Some States have indicated to EPA that they might choose to opt out of EPA’s BEACH Act grant program if their grant amounts are reduced. For these reasons, EPA is considering retaining the use of shoreline miles and coastal population factors in the core allocation formula for the first $10 million of appropriated grant funds and not making any other changes to this formula. C. How Would This Change Affect Current State Funding? Based on grant fund use as of 2008, EPA expects that most States and PO 00000 Frm 00037 Fmt 4703 Sfmt 4703 Territories will not be affected in 2010 because they currently have no unused BEACH Act grant funds that are more than three years old. The expected changes to the allocation formula will affect only those States and Territories that have unspent BEACH Act grant funds that are more than three years old. In 2008, only 7 States and Territories— Alaska, New Hampshire, New Jersey, New York, Ohio, Puerto Rico, and the U.S. Virgin Islands—fall into this category. As noted in Table 4, New Hampshire, New Jersey, and New York all have balances of less than 1 percent of their total BEACH Act grant funds more than three years old. EPA recognizes that Agency accounting practices contributed to the remaining balances in New Jersey and New York, and has worked to ensure that the oldest money is now invoiced first. Under the process EPA is considering, should any State or Territory in 2010 have uninvoiced funds from FY 2001 through FY 2007, EPA would reduce their 2010 grant funding by the amount equal to this older money and redistribute these funds to the other States and Territories. D. How Would EPA Involve States in Developing This Change? EPA intends to reconstitute the workgroup of EPA and State representatives to discuss the details for implementing this change to the allocation formula. EPA will also invite Territorial representatives to the workgroup. E. When Would This Change Become Effective? EPA expects that this change will be effective for the awarding of the 2010 BEACH Act grants. Dated: August 7, 2008. Benjamin H. Grumbles, Assistant Administrator for Water. [FR Doc.

SUPPLEMENTARY INFORMATION: To achieve its mission of protecting human 
health and safeguarding the natural environment, the U.S. Environmental 
Protection Agency (EPA) often employs mathematical models to study 
environmental systems and processes and to inform regulatory decision 
making. The EPA established the Council for Regulatory Environmental 
Modeling (CREM) in 2000 in an effort to improve the quality, 
consistency and transparency of EPA models. At the request of the EPA 
Administrator, the CREM developed the Draft Guidance Document on the 
Development, Evaluation and Application of Regulatory Environmental 
Models (hereinafter Draft Models Guidance, https://www.epa.gov/ord/crem/
library/CREM%20Guidance%20Draft%2012_03.pdf) and the Models Knowledge 
Base (hereinafter Models KBase, https://cfpub.epa.gov/crem/knowledge_
base/knowbase.cfm)
    While the Draft Models Guidance does not impose legally binding 
requirements on EPA or the public, it provides recommendations on the 
principles of good modeling practice, stressing the importance of model 
quality, documentation and transparency with the aim of helping to 
determine when and how a model can be used to inform a decision. The 
Draft Models Guidance was developed in close collaboration with members 
of the CREM, who represent the different EPA program and regional 
offices, and as such, the document represents the consensus view among 
EPA offices. The Draft Models Guidance was also evaluated and approved 
by the EPA's Science Policy Council, the Agency's forum for senior 
level policy deliberation and coordination on significant science 
issues.
    Both the Draft Models Guidance and the Models KBase were issued in 
draft form in November 2003. By providing access to its tools and 
methods, the EPA increases transparency and can improve the public's 
understanding of how sound science is used to make environmental 
decisions. In short, these products are intended to help foster a 
culture of transparency in developing models.
    In addition to internal review within Agency offices and regions, 
the CREM products have undergone an external review process. EPA's 
Science Advisory Board (SAB) formed a CREM Guidance Advisory Panel 
(hereinafter ``the Panel'') to review the Draft Models Guidance and the 
Models KBase. Specifically, the Panel was given seven charge questions 
(which can be found at this URL: https://www.epa.gov/fedreg/EPA-SAB/

2006

[[Page 47164]]

(the report may be found at https://www.epa.gov/sab/panels/
cremgacpanel.html).
    The CREM also commissioned the National Academy of Science (NAS) to 
assess evolving scientific and technical issues related to the 
selection and use of computational and statistical models in decision 
making processes at the EPA. The NAS report which provides advice on 
the management, evaluation and use of models at the EPA was released in 
2007 (the report may be found at https://www.nap.edu/

    This revised draft of the Guidance Document builds on the 
recommendations of the Science Advisory Board review panel and the 
National Research Council report on Models in Environmental Regulatory 
Decision Making.
