TUP-2011-01 Air Monitoring Station at Monta Vista Park Page 2
The objective is to investigate air quality potentially impacted by industrial sources in
Cupertino. The monitoring station was approved by the Director of Community
Development on May 6, 2010 (Exhibit A) with a BAAQMD-suggested effective date of
July 31, 2010. BAAQMD expected to operate the station for a full year from mid-
summer 2010 to 2011.
BAAQMD had internal permitting and construction issues that delayed its construction
until late September 2011. BAAQMD requests a time extension to September 30, 2012
so it may conduct another full year of air quality monitoring.
DISCUSSION
The air quality monitoring station consists of two components:
(1) A trailer with instrumentation that measures or samples the following air
pollutants: ozone, oxides of nitrogen, sulfur dioxide, carbon monoxide,
particulate matter (two size distributions), gaseous hydrocarbon compounds,
and various metals; and
(2) A 30-foot tall, meterological tower mounted with instrumentation to measure
atmospheric conditions.
The existing station complies with its previously issued plannuzg and building
approvals.
The Director of Community Development approves the temporary use permit expiring
September 30, 2012. The fourteen calendar day appeal period will expire on August 2,
2011.

the City Council & Planning Commission in time to allow an appeal of the

DIR-2010-19 Air Monitoring Station at Monta Vista Park Page 2
The objective is to investigate air quality potentially impacted by industrial sources in
Cupertino. The station consists of two parts:
1) A trailer with air quality monitoring instrumentation to be sited in the park parking
lot; and
2) A 30-foot tall meterological tower to collect atmospheric data near the corner of
Foothill Boulevard and Voss Avenue on the grassy field (Attachment 1).
BAAQMD expects to have the monitoring station operational by mid-summer 2010 and
operate it for a full year.
DISCUSSION
The air quality monitoring trailer will have instrumentation to measure or sample the
following air pollutants: ozone, oxides of nitrogen, sulfur dioxide, carbon monoxide,
particulate matter (two size distributions), gaseous hydrocarbon compounds, and
various metals. For security reasons, the trailer will be in a fenced enclosure with
dimensions of 15' x 25' x 8', occupying 3 parking stalls (Attachment 2). The trailer will
need power and telephone connections, available at the recreational building, and
brought to the trailer site on temporary overhead lines.
The meterological tower is a 30-foot tall lattice tower mounted with instrumentation to
measure atmospheric conditions (Attachment 3). The tower does not need power or
telephone connections but must also be fenced in a 5' x 5' enclosure for security reasons.
The tower is sited off of existing walkways in a remote portion of the grassy field away
from the baseball diamond.
Neighborhood Meeting
On April 29, � 2010, BAAQMD and the City held a neighborhood meeting on the
proposed air quality monitoring station at the Monta Vista Recreation Center. Public
notices were sent to neighbors within a 1,000-foot mailing radius of the project site and
the project information was posted on the City website. The Air District, City staff and
19 members of the public were present. Resident questions focused on the types of
chemicals and metals being measured and the appropriate location of the monitoring
station in order to measure air pollutants from the Lehigh Quarry and Cement Plant.
The Air District staff confirmed that their monitoring equipment was very sensitive to
even minute concentrations of pollutants and the District wanted the station in an
urban area close to the general population, so it can assess the quality of the air that
directly affects Cupertino residents.
The Director of Community Development approves the temporary use permit for the
maximum period of one year, effective May 6, 2010 to coincide with future building
permit review and subject to the following conditions of approval:
DIR-2010-19 Air Monitoring Station at Monta Vista Park Page 3
1) The applicant shall provide two to three feet of interior clearance between the trailer
and fence enclosure on the fence sides that face a parking stall or a driveway aisle.
2) The applicant shall place appropriate signs on the monitoring trailer and
meterological tower (or on the enclosing fences) with the Air District's contact
information.
3) This permit is effective for one year from commencement of the operation, or July
31, 2011, whichever is soonest.
The fourteen calendar day appeal period will expire on May 20, 2010.

' ATTACHMENT 1
The Air District would also work with the City of Cupertino to minimize impacts to local residents, to
the extent possible, and would make every effort to mitigate any issues that may arise. While there
� is some noise produced by the instrumentation, the Air District operates identical equipment in
many communities throughout the Bay Area, with no complaints. If the Air District is able to locate
instrumentation as proposed, no tree removal is required.
Fencing would be provided for both the trailer and meteorological tower. The Air District would
work with the City of Cupertino to enhance the aesthetics of the fencing to meet community needs
in a cost effective manner. The outside of the trailer should not produce glare that would affect
local residents.
Description of Equipment
The BAAQMD proposes to locate equipment to measure the following:
Ozone
Oxides of Nitrogen
Sulfur Dioxide
Carbon Monoxide
Particulate Matter (2 size distributions)
Samplers used to determine concentrations of gaseous hydrocarbon compounds
Samplers used to determine concentrations of various metals
Meteorology
Operation of this equipment as well as additional support equipment would require a minimum of
100 amps. The Air District would arrange and pay for power and phone to be located to the trailer.
� No power or phone is required for the meteorological tower.
Location of Equipment and Trailer Specifications
The Air District would provide a trailer to house the above equipment. The trailer enclosure has
dimensions of 16 ft x 7 ft x 8 ft and would require fencing for security purposes. A scan of the
trailer schematic is attached.
It is proposed that the trailer be located in the parking lot, with the only requirement being that it
meets minimum distance from trees and tall structures as defined by the US EPA. Impacts to
parking would be minimized as much as possible.
The Air District would also work with the City of Cupertino to identify an alternate location for the
instrumentation, if desired. Should the City wish to explore this option, the Air District would ensure
that Federal instrument siting criteria were met prior to locating equipment.
We operate instrumentation in cooperation with other Bay Area governmental and private
organizations and would be glad to provide references. We have developed methodologies to
ensure that our operations impact a host facility as little as possible. In addition, we strive to
answer all questions and/or concerns as quickly and successfully as possible to maintain our
working relationships.

4) The source of electrical power will come from a separate electrical circuit within the
main park building. This separate electrical circuit will be installed by an electrical
contractor hired by BAAQMD.
Telephone service will come from a separate telephone line within the main park
building and will be billed to a BAAQMD account.
Both service lines will pass overhead from the main park building to a leased/rented
utility pole within the proposed facility location.

Cupertino Air Monitoring Station Proposal
Summary of Proposal
The Bay Area Air Quality Management District (Air District) proposes locating air monitoring
instrumentation at the parking lot in Monte Vista Park in Cupertino to determine local air quality.
The equipment would be located in or on a trailer located in the area indentified in Attachment A
along with a meteorological tower also identified in Attachment A. The goal of this effort is to
investigate air quality potentially impacted by industrial sources in Cupertino. The Air District would
work in partnership with the City of Cupertino to ensure that local requirements and concerns are
met while expediting the process, to the extent possible, to help answer questions raised by the
local community regarding air quality.
