B. What Should I Consider as I Prepare My Comments for EPA?

    1.  Submitting CBI. Do not submit this information to EPA through 
www.regulations.gov or e-mail. 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.
    2.  Tips for preparing your comments. When submitting comments, 
remember to:
    i. Identify the document by docket ID number and other identifying 
information (subject heading, Federal Register date and page number).
    ii. 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.
    iii. Explain why you agree or disagree; suggest alternatives and 
substitute language for your requested changes.
    iv. Describe any assumptions and provide any technical information 
and/or data that you used.
    v. If you estimate potential costs or burdens, explain how you 
arrived at your estimate in sufficient detail to allow for it to be 
reproduced.
    vi. Provide specific examples to illustrate your concerns and 
suggest alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of 
profanity or personal threats.
     viii. Make sure to submit your comments by the comment period 
deadline identified.
    3. Environmental justice. EPA seeks to achieve environmental 
justice, the fair treatment and meaningful involvement of any group, 
including minority and/or low income populations, in the development, 
implementation, and enforcement of environmental laws, regulations, and 
policies. To help address potential environmental justice issues, the 
Agency seeks information on any groups or segments of the population 
who, as a result of their location, cultural practices, or other 
factors, may have atypical or disproportionately high and adverse human 
health impacts or environmental effects from exposure to the pesticide 
discussed in this document, compared to the general population.

II. What Action is the Agency Taking?

    Under section 18 of the Federal Insecticide, Fungicide, and 
Rodenticide Act (FIFRA) (7 U.S.C. 136p), at the discretion of the 
Administrator, a Federal or State agency may be exempted from any 
provision of FIFRA if the Administrator determines that emergency 
conditions exist which require the exemption. The Hawaii Department of 
Agriculture has requested the Administrator to issue a quarantine 
exemption for the use of calcium hydroxide on outdoor potted and field-
grown ornamental plants, groundcover/floors, and perimeters of 
commercial nurseries to control Eleutherodactylus frogs. Information in 
accordance with 40 CFR part 166 was submitted as part of this request.
    As part of this request, the Hawaii Department of Agriculture 
asserts that calcium hydroxide is necessary to control the tropical 
frogs, Eleutherodactylus coqui and E. planirostris, two relatively new 
species accidentally introduced to Hawaii from infested nursery plants. 
These species are native to the Caribbean, although one or both species 
is established on the continental United States in Florida, Louisiana, 
and Alabama. E. coqui is now firmly established on Maui, and the island 
of Hawaii with smaller populations on Kauai and Oahu; E. planirostris 
is also found on Kauai, Oahu, Maui, and the island of Hawaii. The sites 
where they are established include commercial plant nurseries, 
residential areas, resorts and hotels, forest habitats, and natural 
areas. The Eleutherodactylus coqui and E. planirostris species are 
spread to additional sites primarily through the transportation of 
infested plant materials to uninfested areas.
    Further, the applicant asserts, that there is great concern that 
these tropical frogs pose a threat to the native Hawaiian forest 
ecosystem, including many endangered species. In particular, 
Eleutherodactylus frogs have the potential to be a serious threat to 
native endangered bird species. The E. coqui may exert predation 
pressure on a wide variety of native anthropods, many of which are 
already stressed because of the establishment of other alien predators 
and parasitoids. In addition, these frog species will compete for 
insect food sources with native birds, the majority of which are 
partially or completely insectivorous. The Hawaiian hoary bat and many 
anthropod species also depend upon insects and spiders as food sources. 
According to the quarantine exemption application, another concern is 
that the rapid increase in the populations of these frog species could 
provide a food source and increase the already large populations of

[[Page 28610]]

introduced predators, such as rats and mongooses.
    EPA granted the Hawaii Department of Agriculture a quarantine 
exemption in 2005 for use of calcium hydroxide to control 
Eleutherodactylus frogs. This quarantine exemption program expired on 
April 26, 2008. The applicant withdrew a subsequent request in 2008 for 
use of calcium hydroxide on 4,000 acres of outdoor plant nurseries, 
residential areas, resorts and hotels, parks, forest habitats, and 
natural areas throughout the entire state of Hawaii.
    In this request, the Hawaii Department of Agriculture's projected 
acreage for 2010-2012 is 1,000 acres on outdoor potted and field-grown 
ornamental plants, groundcover/floors, and perimeters of commercial 
nurseries throughout the state of Hawaii in the following counties: 
Honolulu, Maui, Kauai, and Hawaii. According to the current submission, 
use of calcium hydroxide is proposed for application as follows:
    1. For dust application at 500 pounds per acre (485 lbs. active 
ingredient (a.i.) per acre).
    2. For foliar applications on potted or field-grown outdoor 
ornamental plants at 250 pounds of product per acre (242.5 lbs. a.i. 
per acre) at a 3% dilution.
    3. For foliar applications on vegetation of nursery perimeters or 
as a soil drench at 500 pounds per acre (485 lbs. a.i. per acre) at a 
6% dilution. A maximum of twelve applications may be made per site per 
year. Therefore, a total maximum of 18,000,000 lbs. (9,000 tons) of 
product or 17,280,000 lbs. (8,640 tons) of a.i. of calcium hydroxide 
can be applied to treated areas under this request.
    This notice does not constitute a decision by EPA on the 
application itself. The regulations governing section 18 of FIFRA 
require publication of a notice of receipt of an application for a 
quarantine exemption proposing use of calcium hydroxide which has not 
been registered by EPA.
    The notice provides an opportunity for public comment on this 
proposed application.
    The Agency will review and consider all comments received during 
the comment period in determining whether to issue the quarantine 
exemption requested by the Hawaii Department of Agriculture.
