1. EPA REQUIREMENTS FOR AIR MONITORING NETWORK DESCRIPTIONS 

In October 2006, the U.S. EPA issued final regulations concerning state and local agency 

ambient air monitoring networks. In addition, EPA Region III provided guidance in what was to 

be submitted with the first round of a Network Description. Region III requested information 

described in 40 CFR Part 58 §58.10. 

The requirements of 40 CFR Part 58 §58.10 are listed as follow: 

§58.10 (a) requires for each existing and proposed monitoring site: 

1. A statement of purpose for each monitor. 

2. Evidence that siting and operation of each monitor meets the requirements of 

 appendices A, C, D, and E of 40 CFR Part 58, where applicable. 

3. Proposals for any State and Local Air Monitoring station (SLAMS) network 

 modifications. 

§58.10 (b) requires: 

1. The Air Quality System (AQS) site identification number. 

2. The location, including street address and geographical coordinates. 

3. The sampling and analysis method(s) for each measured parameter. 

4. The operating schedules for each monitor. 

5. Any proposals to remove or move a monitoring station within a period of 18 months 

following plan submittal. 

6. The monitoring objective and spatial scale of representativeness for each monitor. 

7. The identification of any sites that are suitable and sites that are not suitable for 

 comparison against the annual PM2.5 NAAQS as described in §58.30. 

8. The Metropolitan Statistical Area (MSA), Core Based Statistical Area (CBSA), 

 Combined Statistical Area (CSA) or other area represented by the monitor.

(2) CHANGES SINCE THE LAST AIR MONITORING NETWORK REVIEW

(2.1) PM Network 

(2.1.1) PM2.5 FRM 

The PM2.5 FRM monitoring network is unchanged since the last network review and continues 

to operate within EPA parameters at all sites. The Allegheny County weighing laboratory 

performed adequately during 2012-2013 but there has been occasional difficulty keeping the 

humidity and temperature within acceptable limits, causing some data loss. Additionally, the 

Caliper/Zymark automated filter weighing system has experienced considerable down time and 

will no longer be supported by the manufacturer. The County laboratory continues to 

successfully weigh PM2.5 filters for ACHD as well as for the State of Delaware’s PM2.5 FRM 

network. 

(2.1.2) PM2.5 Continuous Monitors 

Continuous PM2.5 monitoring remains unchanged since the last network review. A Met One 

BAM 1020 PM2.5 (FEM) monitor is currently installed at the Avalon air monitoring station. 

Thermo Scientific TEOM PM2.5 (SPM) monitors are currently installed at Liberty, Lincoln and 

Lawrenceville NCORE air monitoring stations. 

(2.1.3) PM10 Continuous Monitors 

Continuous PM10 monitoring remains unchanged since the last network review. Met One BAM 

1020 PM10 (FEM) monitors are currently installed at North Braddock and Monroeville air 

monitoring stations. Thermo Scientific TEOM PM10 (FEM) monitors are currently installed at 

Liberty, Glassport, Lincoln and Flag Plaza air monitoring stations. 

(2.2) Sulfur Dioxide Monitoring Network 

Installation of a sulfur dioxide monitor is currently in progress at the North Braddock air 

monitoring site. This installation was initiated after considering the revised sulfur dioxide 

NAAQS, and concerns about meeting the new short term sulfur dioxide standard in this area. 

This monitor should be operational before the final draft of this review is released. 

(2.3) Data Logging Hardware and Software 

During 2012, the monitoring system database was upgraded from the EDAS system to the newer 

Airvision operating system. The Airvision software is installed on a new server which features 

enhanced processing and data storage capabilities. 
A i r M o n i t o r i n g N e t w o r k 2 0 1 3 P a g e | 5

(2.4) Special Study Monitors 

(2.4.1) Lawrenceville Metals Study 

A metals study was initiated in May 2011 on the property of a local metal foundry. Analysis of 

filters gathered by a PM10 high volume sampler is used for this purpose. Exposed filters are 

analyzed for manganese, lead and total chromium. Sampling continues currently on an every 

three day sampling schedule. Future sampling will be based on the decision of the Air Quality 

Program. Ongoing data reports are posted on the Air Quality Program website at the following 

location; 

http://www.achd.net/air/index.html 

(2.4.2) West Allegheny 

In April, 2009, a continuous hydrogen sulfide monitor was installed at the Wilson Elementary 

School in response to numerous odor complaints for local area residents and school staff 

members in regards to emission generated by the nearby residential landfill (see section 7.17 . 

Air Quality Program staff were able to correlate elevated hydrogen sulfide levels with odor 

complaint incidents with a high degree of reliability. The decision was made to keep the 

hydrogen sulfide monitor in place as a surveillance tool to be used by the Air Quality and the 

landfill operators to indicate developing odor problems. Since this monitor has been in operation 

and in coordination with operational improvements at the landfill, odor complaints in this area 

have become less numerous. Hydrogen sulfide is also measured at Avalon and Liberty air 

monitoring sites for similar reasons due to both of these areas being impacted by coke plant 

emissions and associated odors. 

(2.5) 2013 Monitoring Network Review Enhancements 

This monitoring network was enhanced in a few ways to add more accurate and more detailed 

about the Allegheny County Air Monitoring Network as follows; 

• Altitude and probe height measurements were converted from feet to meters 

• Latitude and longitude for each site location was reassessed and listed in finer 

increments. 

• Date established and probe height was added to each monitoring site description. 

• An “Area Information” section was added to each monitoring site description that 

includes daily traffic counts and distance to nearby roads, land area descriptions and 

nearby obstructions to air flow. 
A i r M o n i t o r i n g N e t w o r k 2 0 1 3 P a g e | 6

(3) PROPOSED CHANGES TO THE AIR MONITORING NETWORK 

(3.1) Near Road NO2 Air Monitoring Site 

The MSA (Metropolitan Statistical Area) that includes Allegheny County was selected by the 

EPA to be among first tier of areas that are required to install a near road NO2 air monitoring 

site, in compliance with the recently revised NO2 NAAQS. This site was targeted to be installed 

and operational by January 1, 2013. Delays in the competitive bidding and the contract award 

process caused considerable delays. Unrelated construction at the site and electrical supply 

issues have added additional delays. Currently, construction is underway on the concrete pad 

base and the shelter is targeted to be installed by mid-August, 2013. Arrangements are currently 

underway to supply underground utilities to the monitoring site. Department funds must be 

approved and expended to partially fund a larger underground power supply project to the area. 

EPA guidance was followed in selecting this monitoring site, which is located near the Forest 

Hills/Wilkinsburg exit of the Parkway East (Rt. 376). Parameters to be continuously measured at 

this site include NO2 (nitrogen dioxide), CO (carbon monoxide), Black Carbon (aethalometer), 

and meteorological parameters including wind speed, wind direction, ambient temperature and 

relative humidity using a 10 meter on-site tower. For more information see section 8.19 (page 

78). 

The Primary NO2 NAAQS final rule may be obtained at the following location; 

http://www.gpo.gov/fdsys/pkg/FR-2010-02-09/html/2010-1990.htm

(3.2) Monitor Reductions 

The Air Quality Program plans to permanently remove the following monitors from the network 

during 2013-2014, after the NO2 near road air monitoring site is operational: 

• Downtown Carbon Monoxide Monitor 

Since the carbon monoxide is the only parameter monitored at the Downtown site, this site will 

be discontinued upon removal of the monitor. This site does not meet EPA siting criteria and the 

Parkway East carbon monoxide monitor will be a better measure of maximum roadway 

emissions in Allegheny County. 

• Lawrenceville Oxides of Nitrogen monitor (NO2) 

The Lawrenceville site features an additional oxides of nitrogen monitor, which is a trace level 

NOy monitor that is part of the NCORE suite of instruments. This monitor is much more 

sensitive and of more current design than the standard sensitivity NO2 monitor that is also in 

operation at that same site. 
A i r M o n i t o r i n g N e t w o r k 2 0 1 3 P a g e | 7

Additionally, the new near road NO2 monitor will be a new trace level design and will be 

optimally located to capture maximum roadway emissions as an important aspect of the site 

location. 

(3.3) PM2.5 Weighing Laboratory 

The Air Quality Program has approved the purchase a new automated PM2.5 filter weighing 

system which is currently on order. Additionally, a self-enclosed environmentally controlled 

chamber is included as part of the purchase to help improve unstable humidity and temperature 

conditions of the current weighing room. 

(3.4) Harrison Monitoring Site Relocation 

The Highlands School District has notified the Air Quality Program that the building that 

currently houses the ozone and nitrogen dioxide monitors (see section 8.6, Harrison) has been 

put up for sale. Due to the condition of the building, demolition is a likely result of a change of 

ownership. Arrangements have been made to move the monitors to the Harrison 2 air 

monitoring site and this project is currently in progress. The Harrison 2 air monitoring site is 

currently a PM2.5 FRM monitoring site that is within 1 kilometer of the Harrison air monitoring 

site. The Harrison 2 site will feature a more unrestricted air flow, will better meet gaseous 

monitor siting criteria and represents an overall improvement to the air monitoring network 

design. The Air Quality Program intends to complete the current ozone season before the ozone 

and nitrogen dioxide monitors are moved (October 1, 2013), but the move will be performed 

earlier if the building is sold sooner than that date.

Latitude (N) 40°19'25.88 Longitude (W) 79°52'5.03 

Established 10/01/1969 Probe Height 4 m 

Comments This site is population oriented but is also about 3 km downwind of the US Steel Clairton 

Coke Works, which is a major source of particulates and precursor gases as well as sulfur 

dioxide and air toxics. The area around this monitoring site has a long history of high 

levels of PM2.5, PM10 and sulfur dioxide. Significant ambient levels of benzene have also 

been measured and documented at this site. Liberty is a core PM2.5 site that is used to 

determine compliance with national standards. 

At the request of US Steel, telemetry devices have been installed on the PM10, PM2.5, SO2, 

H2S and benzene monitors that transmit continuous readings via radio signals to a location 

within the US Steel facility. Other transmitters are also in use at Lincoln PM10 and PM2.5 

monitors (site # 8.3) and at the Glassport High Street PM10 monitor (site # 8.4). This realtime data allows US Steel to minimize fugitive emissions and to adjust production levels to 

keep particulate levels and gaseous emissions within allowable ambient levels in 

downwind communities.
