NETWORK WAIVER REQU E STS

Burbank

The Palm Avenue Burbank air monitoring site was decommissioned During June, 2014 at the

request of the property owner. Currently SCAQMD is working with LADWP to relocate to a

site within one mile of the former si te. EPA was informed of this closure via email in prior to its

closure

.

At the time of closure, the Burbank was the DV location for the Los Angeles CBSA with a 24

hour value of 30.8 ug/m3 and Mira Loma the basin DV at 36.6 ug/m3. This year the DV site f or

the Los Angeles is the Los Angeles Main site at 32.0 ug/m3 and basin DV Mira Loma at 36.6

ug/m3. SCAQMD is working in consultation with EPA to establish a new site to represent

Burbank in FY 2015

- 2016. It is requested a waiver be granted for suspensi on of monitoring

until a suitable replacement site can be located

. Even with the site closure, SCAQMD exceeds

the minimum monitoring requirements for all criteria pollutants and monitoring programs.

Long Beach

The North Long Beach air monitoring site was decommissioned during September, 2013 at the

request of the property owner

. Currently SCAQMD is working with Long Beach Public Health

to relocate to a site within one mile of the former site. EPA was informed of this closure via

email in prior to closure . A separate smaller site at the rear of the facility remains open

measuring PM2.5 FRM particulate.

Even with the site closure, SCAQMD exceeds the minimum monitoring requirements for all

criteria pollutants and monitoring programs. SCAQMD is working i n consultation with EPA to

establish a new site to represent Burbank in FY 2015

- 2016. It is requested a waiver be granted

for suspension of monitoring until a suitable replacement site can be located.

Ontario

The Ontario (Fire Station) air monitoring sit e was decommissioned during June, 2014 at the

request of the property owner. Currently SCAQMD is working with San Bernardino County

Public Health to consolidate measurements with nearby sites. EPA was informed of this closure

via email prior to its closur e. At the time of closure, Ontario was a collocated site for PM10. In

order to meet the minimum collocation requirements a PM10 was relocated to the Mira Loma

(Van Buren) site.

Even with the site closure, SCAQMD exceeds the minimum monitoring requireme nts for all

criteria pollutants and monitoring programs. It is requested a waiver be granted to discontinue

monitoring at Ontario.

Riverside Magnolia

The Riverside Magnolia air monitoring site was decommissioned during March 2015 at the end

of the lease d ue to safety issues. Currently SCAQMD is assessing relocation of the site and

considering underrepresented areas identified in the 5 year network assessment. EPA wasAir Quality Monitoring Network Plan

– July 2015

Appendix D Page 2 informed of this closure via email prior to its closure . Even with the site closure, SCAQ MD

exceeds the minimum monitoring requirements for all criteria pollutants and monitoring

programs. It is requested a waiver be granted to discontinue monitoring until a suitable

replacement site is identified, and located based upon the 5 year network ass essment.

Crestline

The Crestline air monitoring site is located on the grounds of the Lake Gregory, San Bernardino

County Regional Park within the San Bernardino National Forest. The site began operation in

October, 1973 and has at times been a design va lue site for ozone. Since the time of its

inception, trees adjacent to the facility have grown to a height greater than the inlet probe.

Because these trees are parallel to the site a majority of the time they are not considered an

obstruction per 40 CFR 58 Appendix E. Readings remain unaffected since the nearest tree is at

10 meters from the inlet probe and the predominant wind direction is from the west. A wind rose

showing direction for 2014 is shown below. It is requested a waiver be granted for si ting at

Crestline based on predominant wind direction and continuity of data.

Appendix D Page 4 Rubidoux

The Rubidoux air monitoring site is located on property owned by Southern California Edison.

The site began operation in September, 1972. Since that time trees north east of the particulate

samplers have grown to a height exceeding siting criteria; however measurements remain

unaffected since the predominant wind direction is parallel to trees. Contract revisions are

currently being negotiated with Southern California Edison to allow for extra space to move the

particulate samplers further from trees to better meet EPA siting criteria. The changes to the

contract and particulate sampler move are expected to take place during 2015. A waiver is

requested to continue monitoring while monitors can be moved to better meet EPA siting

criteria.

Appendix D Page 6 Pasadena

The Pasadena air monitoring site is located on property owned by Caltech Pasadena. The site

began oper ation in April, 1982. Since that time trees east and west of the particulate samplers

have grown to a height exceeding siting criteria and while they can be considered an obstruction,

i t is requested a waiver be granted to continue morning based on popula tion exposure. Longer

term the site is being examined in the 5 year network assessment for consolidation with nearby

sites. Decisions regarding site consolidation will be made in consultation with EPA Region IX

representatives. It is requested a waive r be granted for siting at Pasadena until the site can be

moved to a more representative location.

Appendix D Page 8 Pomona

The Pomona air monitoring site has been in operation since June, 1965. The site was originally a

microscale site for carbon monoxide. Since the time of inception it was noted trees south of the

site grew to be an obstruction, however they were trimmed during December, 2014 to a height

below the inlet. It is requested a waiver be granted for Pomona based on site maintenance and

data continuity until the 5 year network assessment is complete and recommendations for the site

can be discussed and implemented.

Appendix D Page 10 Anaheim

The Anaheim air monitoring site is located on Anaheim City School District property. The site

began operation in August, 2001. The site was originally anticipated as a temporary location

however since then it has become permanen t. Because of this there are siting issues including

palm trees and proximity to the nearest traffic lane of the residential street (at 8m north from the

inlet probes). Measurements remain unaffected predominant majority of the time the wind

direction is from the south, the palm trees are minimal obstruction, and traffic is residential. It is

requested a waiver be granted for siting at Anaheim based on the preceding data. Longer term

the site is scheduled to be renovated placing the inlet probes at grea ter than 10m from the traffic

lanes and trees.

Appendix D Page 12 Hudson

The Hudson air monitoring site is located on Long Beach Unified School District property. The

site began operation as part of the MATES IV project. The site was originally anticipated as a

temporary location however since then it has become permanent, monitoring potential emissions

from the nearby the ports of Los Angeles, Long Beach and Terminal Island Freeway. Because of

this there are siting issues including p roximity to the nearest traffic lane. Measurements remain

unaffected since the predominant wind direction is from the south west and the roadway is to the

east. It is requested a waiver be granted for siting at Hudson based on predominant wind

direction. Longer term the site is being examined closely in the 5 year network assessment for

consolidation with nearby sites.

Appendix D Page 14 South Long Beach

The South Long Beach air monitoring site is located on the Long Beach City College campus.

The site was established to focus on particulate emissions from the Ports of Long Beach and Los

Angeles. Since the inception of the site, the college has expanded, storing temporary containers

nearby, constructing new buildings and expand ing parking. Because of this there are potential

siting issues. It is requested a waiver be granted for siting at South Long Beach based on

predominant wind direction and continuity of data collection focused on population exposure.

Longer term the si te is being examined closely in the 5 year network assessment for

consolidation with nearby sites.

Appendix D Page 16 Fontana

The Fontana air monitoring site has been in operation since August, 1981. Since the time of

inception i t was noted a wall downwind of the site exceeded the height of the inlet probes as did

a nearby building. The adjacent wall and building are greater than the 2m minimum distance

requirement and meet the, “ twice the height that the obstacle protrudes above the probe, inlet, or

monitoring path ” requirement in 40 CFR 58 Appendix E. Measurements also remain unaffected

since the predominant wind direction is from the south west. It is requested a waiver be granted

for siting at Fontana.
