We are proposing to amend the Plant Protection and Quarantine Treatment Manual, which is incorporated by reference in the Code of Federal Regulations, to allow leaves of the California bay laurel (Umbellularia californica) to be treated with vacuum heat before being moved interstate from any area quarantined because of Phytophthora ramorum. This action would provide an alternative to the currently approved hot water dip used to treat greenery of host plants, specifically California bay laurel leaves, which ruins the suitability of the leaves for use as a dried spice.

Phytophthora ramorum is a harmful fungus that attacks certain plants, particularly trees and shrubs. P. ramorum is also commonly referred to as sudden oak death or ramorum leaf blight and ramorum dieback. Symptoms of infection may include new growth that droops or turns from yellow to brown, the appearance of a bleeding canker; burgundy-red to tar-black thick sap oozing on the bark surface, or leaf spotting and stem canker infections.
The regulations in “Subpart—Phytophthora Ramorum” (7 CFR 301.92 through 301.92-11, referred to below as the regulations) list 10 counties in California and a portion of Curry County in Oregon as quarantined areas and restrict the interstate movement of regulated articles from those areas.
In addition, on December 21, 2004, the Animal and Plant Health Inspection Service (APHIS) issued a Federal Order, effective January 10, 2005, which expands the list of quarantined areas to include Contra Costa, Humboldt, Lake, and San Francisco Counties, CA, as well as another portion of Curry County, OR. This order replaces the order of April 22, 2004, and the clarification of that order which was issued on April 23, 2004. The December 21, 2004, order is available on the Internet at http://www.aphis.usda.gov/ppq/ispm/sod/.
Regulated articles are identified in § 301.92-2 of the regulations. The list of regulated articles includes, among other things, unprocessed wreaths, garlands, and greenery of arrowwood (Viburnum x bodnantense), big leaf maple (Acer macrophyllum), black oak (Quercus kelloggii), California bay laurel (Umbellularia californica), California buckeye (Aesculus californica), California coffeeberry (Rhamnus californica), California honeysuckle (Lonicera hispidula), coast live oak (Quercus agrifolia), huckleberry (Vaccinium ovatum) (except fruit), madrone (Arbutus menziesii), manzanita (Arctostaphylos manzanita.), rhododendron (Rhododendron spp., including azalea), Shreve's oak (Quercus parvula var. shrevei), tanoak (Lithocarpus densiflorus), and Toyon (Heteromeles arbutifolia).
In the December 21, 2004, Federal Order, APHIS expanded the list of regulated articles to include 16 additional confirmed hosts of P. ramorum. These additional regulated articles are: Camellia spp., Canyon live oak (Quercus chrysolepis), coast redwood (Sequoia sempervirens), doublefile viburnum (Viburnum plicatum var. tomentosum), Douglas fir (Pseudotsuga menziesii var. menziesii), False Solomon's Seal (Maianthemum racemosum formerly Smilacina racemosa), Fraser's Photinia or Red tip (Photinia fraseri), Heather (Calluna vulgaris), Himalaya pieris (Pieris formosa), Japanese pieris (Pieris japonica), laurustinus (Viburnum tinus), pieris “Brouwer's Beauty” (Pieris floribunda x japonica), pieris “Forest Flame” (Pieris formosa x japonica), western starflower (Trientalis latifolia), witch hazel (Hamamelis virginiana), and wood rose (Rosa gymnocarpa).
Regulated articles must meet the conditions specified in the regulations before they may be moved interstate from a quarantined area. One of the conditions for movement is treatment. The Plant Protection and Quarantine Treatment Manual (PPQ Treatment Manual), which is maintained by APHIS, contains approved treatment schedules for many plant pests and diseases and is incorporated by Start Printed Page 6597reference into the Code of Federal Regulations at 7 CFR 300.1. Approved treatments for some articles can also be found in the regulations. Currently, the only approved treatment for unprocessed wreaths, garlands, and greenery of host plants moving interstate from the quarantined areas is listed in § 301.92-10 of the regulations. This treatment consists of a hot water dip for 1 hour at a sustained temperature of at least 160° F. However, this treatment is not a viable option for treating leaves from the California bay laurel (Umbellularia californica), as it ruins the leaves for their intended use as a dried spice.
APHIS has received several requests from a spice company in California to approve the use of vacuum heat treatment as an alternative method of treatment for California bay laurel leaves that are moving interstate from a quarantined area for use as a dried spice. Vacuum heat treatment is an already existing industry standard method for treating California bay laurel leaves harvested outside the quarantined area. Research  conducted by APHIS’ Treatment Quality Assurance Unit at the Center for Plant Health Science and Technology has demonstrated that vacuum heat treatment effectively eliminates P. ramorum on leaves of the California bay laurel. Therefore, we are proposing to amend the PPQ Treatment Manual to add vacuum heat treatment as an acceptable treatment method for bay leaves used as a dried spice. This action would provide an alternative to the hot water dip that is currently being used to treat greenery of the California bay laurel in the quarantined areas. The treatment procedure we would add to the PPQ Treatment Manual is described in the following paragraph.
Place greenery in a vacuum chamber. Starting at 0 hour, gradually reduce to 0.133 Kpa vacuum at 8 hours. Maintain the vacuum until the end of the treatment. Gradually increase the temperature in the vacuum chamber from ambient temperature at 0 hour to 60 °C at 5 hours. After 5 hours, gradually lower the temperature to 30 °C at 22 hours. The length of the treatment is 22 hours.
In addition to adding this vacuum heat treatment schedule, which would be designated as T101-m-2-1-2, to the PPQ Treatment Manual, we would also amend the PPQ Treatment Manual's incorporation by reference in 7 CFR 300.1 to reflect the date of the treatment's inclusion in the manual. In addition, we would amend the list of accepted treatments in § 301.92-10 to include any treatments authorized for use on P. ramorum that are listed in the PPQ Treatment Manual.
Executive Order 12866 and Regulatory Flexibility Act
This rule has been reviewed under Executive Order 12866. For this action, the Office of Management and Budget has waived its review under Executive Order 12866.
We are proposing to amend the PPQ Treatment Manual to allow leaves of the California bay laurel to be treated with vacuum heat before being moved interstate from any area quarantined because of P. ramorum. This action would provide an alternative to the currently approved hot water dip used to treat California bay laurel leaves, which ruins the suitability of the leaves for use as a dried spice.
Vacuum heat treatment costs are similar to costs of vapor heat and hot-air treatment systems. All three treatments require substantial initial capital investments ranging from $55,000 to $200,000 for larger commercial facilities. By comparison, hot water immersion treatment systems can be assembled for less than $8,000. Clearly, hot-water immersion treatment is less expensive, but in this case it is not feasible because it renders the treated article-bay leaves-unsuitable for its use as a dried spice.
Table 1 shows that representative unit costs for hot air or vapor heat treatments total less than $30 per ton of commodities treated. The cost of vacuum heat treatment is comparable. This cost is higher than the unit cost of hot water immersion, given the large difference in capital costs indicated above, but is relatively minor when compared to the value of the commodity being treated.
|Capital costs||$4.41/metric ton of commodity treated.|
|Operating costs1||$25.00/metric ton of commodity treated.|
|Total cost||$29.41/metric ton of commodity treated.|
|1 Labor, energy, maintenance, and insurance.|
One pound of dried bay leaves sells for $3.75, that is, $8,267.33 per metric ton. Thus, the representative cost shown in table 1 is equal to less than 0.4 percent of the sales price of the spice. Compared to other costs, such as harvesting, storage, processing, packaging, and transport, the cost of the vacuum heat treatment is relatively insignificant overall.
We also note that use of the vacuum heat treatment would be on a voluntary basis to qualify dried bay leaves for interstate movement from the quarantined counties.
According to the 2002 Agricultural Census, there were approximately 600 nurseries in the 14 California counties operating under quarantine for P. ramorum. The 600 nurseries reported approximately $882 million in annual sales. A small nursery, according to Small Business Administration size standards (SBA), is one with $750,000 or less in annual receipts. APHIS does not have information on the size distribution of the nurseries in the 14 counties, in terms of annual receipts. We also do not have information on the number of these nurseries that have bay laurel trees and seedlings for sale, or of the quantity of bay laurel leaves they produce and the percentage sold to customers outside the quarantined area.
It is expected that, primarily, producers/processors of bay leaves will conduct the vacuum heat treatment. According to the 2002 Economic Census, there were approximately 44 spice and extract manufacturing establishments (NAICS 311942) in California, employing 1,521 people (or an average of 34 persons per entity). No data are available for California by county. According to the SBA definition, the size standard for a small entity in this industry is 500 or fewer employees. However, information on the size distribution of these establishments was unavailable. Even though the number and size of the entities that could be affected by the proposed rule is unknown, we have no evidence indicating that there would be a significant economic impact on any entity, large or small.
Under these circumstances, the Administrator of the Animal and Plant Health Inspection Service has determined that this action would not have a significant economic impact on a substantial number of small entities.
