Calcium Hydroxide; Receipt of Application for Emergency Exemption 
Solicitation of Public Comment

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: EPA has received a quarantine exemption request from the 
Hawaii Department of Agriculture to use the pesticide calcium hydroxide 
(CAS No. 1305-62-0) to treat up to 4,000 acres of outdoor plants in 
nurseries, residential areas, parks, hotels and resorts, forest 
habitats, and natural areas to control Coqui and Greenhouse frogs. The 
applicant proposes the use of a new chemical which has not been 
registered by EPA. This is the second request by the State of Hawaii.
    EPA is soliciting public comment before making the decision whether 
or not to grant the exemption.

    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.

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 plants in 
nurseries and residential areas, parks, hotels and resorts, forest 
habitats, and natural areas to control Coqui and Greenhouse 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 it is necessary to control the Coqui and Greenhouse frogs 
(Eleutherodactylus coqui and E. planirostris) in areas of Hawaii where 
they have accidentally been introduced via infected nursery plants. 
These tropical frogs are not native to Hawaii, but come from the 
Caribbean, although one or both species is established on the 
continental United States in Florida, Louisiana, and Alabama. There is 
great concern that the frogs have the potential to cause serious damage 
to the native Hawaiian forest ecosystems, including endangered and 
threatened species. E. Coqui is now firmly established on Maui and the 
island of Hawaii with smaller populations on Kaui and Oahu. E. 
planirostris is also found on Kaui, Oahu, Maui, and the island of 
Hawaii. The sites where they are established include commercial plant 
nurseries, residential areas, resorts, hotels, parks, forest habitats 
and natural areas. These species are spread to additional sites 
primarily through the transportation of infested plant materials to 
uninfested sites.
    The applicant asserts that these frogs pose a serious threat to 
both agriculture and to the native Hawaiian forest ecosystems, 
including many endangered species. In particular, Eleutherodactylus 
frogs have the potential to be a serious threat to native endangered 
bird species. The E. cocqi may exert predation pressure on a wide 
variety of native anthropods, many of which are already stressed due to 
the establishment of other alien predators and parasitoids. 
Additionally, these frog species will compete for insect food sources 
with the 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 a food source, 
According to the quarantine exemption application, another concern is 
that the rapid increase in populations of these frog species could 
provide a food source for and enhance the already large populations of 
introduced predators, such as rats and mongooses.
    In 2005, EPA granted the Hawaii Department of Agriculture a 
quarantine exemption for use of calcium hydroxide to control the 
Eleutherodactylus frogs. This quarantine exemption program expired on 
April 26, 2008.
    In this request, the applicant's projected acreage for 2008-2010 is 
4,000 acres on outdoor plant nurseries, residential areas, resorts and 
hotels, parks, forest habitats, and natural areas throughout the entire 
state of Hawaii. According to the current request, use of calcium 
hydroxide is proposed for application as follows:
    1. As dust application (to soil surface only) at a maximum rate of 
500 lbs. of product per acre (485 lbs. a.i. per acre);
    2. In combination with water as soil drench with application 
equipment at a maximum rate of 950 lbs. of product per acre (921.5 lbs. 
a.i. per acre); or
    3. In combination with water as foliar application with ground 
equipment at a maximum rate of 500 lbs. of product per acre (485 lbs. 
a.i. per acre). A maximum of twelve applications may be made per year. 
Therefore, a total maximum of 136,800,000 lbs. of product or 
132,696,000 lbs. a.i of calcium hydroxide could 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.
    An analogous exemption program intended to control introduced frogs 
in Hawaii involving calcium hydroxide recently expired and drew public 
interest. 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.
