Notice of Seasonal Closure of Public Lands

AGENCY: Bureau of Land Management, Department of the Interior.

ACTION: Notice of seasonal closure of certain public lands referred to 
as the Serpentine Area of Critical Environmental Concern (ACEC), 
located in the southern portion of San Benito County and western Fresno 
County, Central Coast region of California, to motorized and non-
motorized recreation use.

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

SUMMARY: Pursuant to 43 Code of Federal Regulations (CFR) subpart 8364, 
notice is hereby given that the Bureau of Land Management (BLM), 
Hollister Field Office will seasonally restrict public access to 
certain BLM-administered public lands during the period of June 1, 2006 
through October 15, 2006. This seasonal closure is needed to ensure 
visitor safety and protect public land users from potential health 
risks associated with naturally occurring asbestos found within the 
closure area.
    This seasonal closure affects public lands located within the 
30,000-acre Serpentine Area of Critical Environmental Concern (ACEC) 
situated within the Clear Creek Management Area (CCMA). Public access 
within this area will only be allowed on county roads and the following 
route segments: R011 to Wright Mountain Gate, R016, T153 from the 
junction of R011 to San Carlos peak, and R02 to the junction of T107. 
Limited non-motorized use will be allowed adjacent to the routes 
identified above, or by written authorization from the Hollister Field 
Manager. Personnel of the BLM, California Department of Fish and Game, 
U.S. Fish & Wildlife Service, and law enforcement, fire, and emergency 
personnel are exempt from this closure only when performing official 
duties. Operators of communication facilities may perform maintenance 
activities; livestock operators may perform permitted activities, and 
private in-holders may access their private property, as approved.

DATES: This seasonal closure will be effective from June 1, 2006 
through October 15, 2006.

FOR FURTHER INFORMATION CONTACT: Rick Cooper, Field Office Manager, 
BLM, Hollister Field Office, 20 Hamilton Court, Hollister, California 
95023. Telephone: 831-630-5010 Fax: 831-630-5055, during regular 
business hours, 7:30 a.m. to 4 p.m., Monday through Friday, except 
holidays.

SUPPLEMENTARY INFORMATION: The CCMA is a popular location for off-
highway vehicle (OHV) recreation. A variety of other recreation 
activities also occur within the CCMA, including hunting, rock-
hounding, wildlife watching, and hiking. This is a unique geological 
area with serpentine soils and a suite of rare plants and animals. The 
type and level of OHV use also must be carefully managed to create an 
environment that promotes the health and safety of visitors.
    BLM will be restricting public access during the dry season within 
the CCMA, in response to studies being conducted by the U.S. 
Environmental Protection Agency (EPA), which are analyzing the levels 
of exposure to naturally occurring asbestos for various recreation 
activities at the CCMA. Studies conducted by EPA in September and 
November of 2004 found elevated levels of airborne asbestos fibers 
present during various recreation activities. This action is also in 
accordance with the 1995 Final Environmental Impact Statement (FEIS) 
and Resource Management Plan Amendment for the CCMA.
    The soil moisture during the time period of June through October is 
at the lowest point and therefore the dust generating potential and 
release of naturally occurring airborne asbestos is greatest. Analysis 
of airborne asbestos exposure reflected in EPA's Technical Memorandum 
issued February 5, 2005, titled ``Human Health Risk Assessment--
Asbestos Air Sampling Clear Creek Management Area, California,'' based 
on samples collected September 15, 2004, indicate a higher risk from 
airborne asbestos exposure in

CCMA than EPA and BLM previously thought. Based on preliminary EPA 
results, use restrictions in CCMA may be needed to reduce risk to the 
public from asbestos exposure, particularly during the dry season.

Closure Order

    Pursuant to 43 CFR 8364.1, notice is hereby given that the BLM is 
seasonally restricting access to portions of public lands within the 
Clear Creek Management Area (CCMA) located in the southern portion of 
San Benito County and western Fresno County, California. Public access, 
including motorized and non-motorized recreation use is restricted on 
public lands within the Serpentine ACEC from June 1, 2006 through 
October 15, 2006. Limited non-motorized use will be allowed adjacent to 
the routes identified in this Closure Order. These lands are located in 
the Mount Diablo Meridian in portions of T.17 S., R. 11 E.; T. 17 S., 
R. 12 E.; T. 18 S., R 11 E.; T. 18 S., R. 12 E.; T. 18 S., R. 13 E.; T. 
19 S., R. 13 E.
    This seasonal closure is necessary to ensure visitor safety and 
protect public land users from potential health risks associated with 
naturally occurring asbestos found within the restricted area. Dry soil 
conditions and high dust generating potential from public use 
activities during this time period create the greatest hazard and risk 
associated with exposure to asbestos.
    Except for travel on San Benito County roads and the following 
route segments: R011 to Wright Mountain Gate, R016, T153 from the 
junction of R011 to San Carlos Peak, and R02 to the junction of T107, 
all public access and motorized vehicle travel within the Serpentine 
ACEC will be allowed only by written authorization of the Hollister 
Field Manager. The following persons are exempt from the identified 
restrictions:
    (1) Federal, State, or local law enforcement officers, while 
engaged in the execution of their official duties.
    (2) BLM personnel or their representatives while engaged in the 
execution of their official duties.
    (3) Any member of an organized rescue, fire-fighting force, or 
emergency medical services organization while in the performance of 
their official duties.
    (4) Any member of a Federal, state, or local public works 
department while in the performance of an official duty.
    (5) Any person in receipt of a written authorization of exemption 
obtained from the authorized officer from the Hollister Field Office.
    (6) Private landowners with in-holdings within the restricted area 
who have a responsibility or need to access their property, and persons 
with valid existing rights-of-way, mining claims, or lease operations, 
or representatives thereof.
    During the closure period, the area will be clearly posted. Closure 
signs will be posted at main entry points to all locations affected by 
this Notice. Maps of the area will be posted with this notice at key 
locations that provide access into the closure areas, and may be 
obtained with further information at the Hollister Field Office, 20 
Hamilton Court, Hollister, California 95023.
    Seasonal closure orders may be implemented as provided in 43 CFR, 
subpart 8364.1. Violations of this closure are punishable by a fine not 
to exceed $1,000 and/or imprisonment not to exceed 12 months.

    Dated: April 21, 2006.
Rick Cooper,
Hollister Field Office Manager.
