1. EPA REQUIREMENTS FOR AIR MONITORING NETWORK DES CRIPTIONS

In October 2006, the U.S. EPA issued final regulati ons 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 Desc ription. Region III requested information described in 40 CFR Part 58 §58.10.

The requirements of 40 CFR Part 58 §58.10 are liste d 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 st ation (SLAMS) network modifications.

§58.10 (b) requires: 1. The Air Quality System (AQS) site identification nu mber. 2. The location, including street address and geograph ical coordinates. 3. The sampling and analysis method(s) for each measur ed parameter. 4. The operating schedules for each monitor. 5. Any proposals to remove or move a monitoring statio n within a period of 18 months following plan submittal. 6. The monitoring objective and spatial scale of repre sentativeness for each monitor. 7. The identification of any sites that are suitable a nd sites that are not suitable for comparison against the annual PM2.5 NAAQS as descr ibed in §58.30. 8. The Metropolitan Statistical Area (MSA), Core Based Statistical Area (CBSA), Combined Statistical Area (CSA) or other area repr esented by the monitor.

(2) CHANGES SINCE THE LAST AIR MONITORING NETWORK REVIEW

(2.1) PM Network

(2.1.1) PM 2.5 

### 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. T he County laboratory continues to successfully weigh PM 2.5 

### filters for ACHD as well as for the State of Delaw are’s PM 2.5 

### FRM network.

(2.1.2) PM 2.5 

### Continuous Monitors

Continuous PM2.5 monitoring remains unchanged since the last network review. A Met One BAM 1020 PM 2.5 

### (FEM) monitor is currently installed at the Avalon air monitoring station. Thermo Scientific TEOM PM2.5 (SPM) monitors are cur rently installed at Liberty, Lincoln and Lawrenceville NCORE air monitoring stations.

(2.1.3) PM 10 

### Continuous Monitors

Continuous PM 10 

### monitoring remains unchanged since the last networ k review. Met One BAM 1020 PM 10 

### (FEM) monitors are currently installed at North Bra ddock and Monroeville air monitoring stations. Thermo Scientific TEOM PM 10 

### (FEM) monitors are currently installed at Liberty, Glassport, Lincoln and Flag Plaza air moni toring stations.

(2.2) Sulfur Dioxide Monitoring Network

Installation of a sulfur dioxide monitor is current ly in progress at the North Braddock air monitoring site. This installation was initiated a fter considering the revised sulfur dioxide NAAQS, and concerns about meeting the new short ter m 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 upg raded 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 pro perty of a local metal foundry. Analysis of filters gathered by a PM10 high volume sampler is u sed for this purpose. Exposed filters are analyzed for manganese, lead and total chromium. S ampling 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 Ai r 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 monit or 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 nea rby residential landfill (see section 7.17 . Air Quality Program staff were able to correlate el evated hydrogen sulfide levels with odor complaint incidents with a high degree of reliabili ty. 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 prob lems. Since this monitor has been in operation and in coordination with operational improvements a t the landfill, odor complaints in this area have become less numerous. Hydrogen sulfide is als o 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 a s follows;

• Altitude and probe height measurements were convert ed from feet to meters

• Latitude and longitude for each site location was r eassessed 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 mon itoring site description that includes daily traffic counts and distance to nearb y roads, land area descriptions and nearby obstructions to air flow.

(3) PROPOSED CHANGES TO THE AIR MONITORING NETWORK

(3.1) Near Road NO 2 

### Air Monitoring Site

The MSA (Metropolitan Statistical Area) that includ es Allegheny County was selected by the EPA to be among first tier of areas that are requir ed to install a near road NO 2 

### air monitoring site, in compliance with the recently revised NO 2 

### 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 cons truction at the site and electrical supply issues have added additional delays. Currently, co nstruction 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 mon itoring site. Department funds must be approved and expended to partially fund a larger un derground power supply project to the area.

EPA guidance was followed in selecting this monitor ing 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 NO 2 

### (nitrogen dioxide), CO (carbon monoxide), Black Car bon (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 NO 2 

### NAAQS final rule may be obtained at the following location;

http://www.gpo.gov/fdsys/pkg/FR-2010-02-09/html/201 0-1990.htm

(3.2) Monitor Reductions

The Air Quality Program plans to permanently remove the following monitors from the network during 2013-2014, after the NO 2 

### near road air monitoring site is operational:

• Downtown Carbon Monoxide Monitor

Since the carbon monoxide is the only parameter mon itored 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 bett er measure of maximum roadway emissions in Allegheny County.

• Lawrenceville Oxides of Nitrogen monitor (NO 2 

### )

The Lawrenceville site features an additional oxide s of nitrogen monitor, which is a trace level NO y 

### monitor that is part of the NCORE suite of instrum ents. This monitor is much more sensitive and of more current design than the stand ard sensitivity NO 2 

### 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 NO 2 

### monitor will be a new trace level design and will be optimally located to capture maximum roadway emissi ons 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 mon itors (see section 8.6, Harrison) has been put up for sale. Due to the condition of the build ing, 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 pr ogress. The Harrison 2 air monitoring site is currently a PM2.5 FRM monitoring site that is withi n 1 kilometer of the Harrison air monitoring site. The Harrison 2 site will feature a more unre stricted air flow, will better meet gaseous monitor siting criteria and represents an overall i mprovement to the air monitoring network design. The Air Quality Program intends to complet e 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 da te.

Established 10/01/1969 Probe Height 4 m

Comments This site is population oriented but is al so 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 monit oring site has a long history of high levels of PM2.5, PM10 and sulfur dioxide. Signific ant 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 PM 10 , PM 2.5 , SO 2 , H 2 S and benzene monitors that transmit continuous rea dings via radio signals to a location within the US Steel facility. Other transmitters a re also in use at Lincoln PM10 and PM2.5 monitors (site # 8.3) and at the Glassport High Str eet PM10 monitor (site # 8.4). This realtime data allows US Steel to minimize fugitive emis sions and to adjust production levels to keep particulate levels and gaseous emissions withi n allowable ambient levels in downwind communities.
