INTRODUCTION

This report provides an assessment of the existing monitoring network and proposed changes in 

the Louisiana Ambient Air Quality Network that will continue to meet the data requirements 

necessary for air quality management and to adjust for resource and financial constraints. The 

assessment incorporates: 1) current monitoring regulatory requirements, 2) newly proposed air 

monitoring regulations, and 3) requirements under both State Implementation and Maintenance 

Plans. This assessment focuses on National Ambient Air Quality Standard (NAAQS) pollutants 

that exceed or approach any standard in populated areas. The proposed network reduces the 

monitoring of selected pollutants that clearly meet the standard, consolidates monitoring of 

different pollutants in a region at fewer sites, and eliminates redundant monitors measuring the 

same air mass.

This proposed network meets or exceeds current monitoring regulatory requirements for the 

numbers and types of air monitors in each region of the state and will meet the minimum 

requirements in EPA’s proposed air network regulations. In addition it provides a foundation for 

the future that will be more effective in providing information to develop air pollution control 

strategies and to inform the public on air quality conditions.

AIR QUALITY OVERVIEW

The national primary ambient air quality standards define levels of air quality that are necessary, 

with an adequate margin of safety, to protect human health. There are six common pollutants 

that are referred to as the criteria pollutants. For each the State and EPA track the concentration 

in the ambient air. The Louisiana Ambient Air Quality Network provides these measurements to 

insure public health is protected.

This air quality review provides an overview of current air quality conditions of each criteria 

pollutant. This provides a perspective on the pollutants of greatest concern and the regions of the 

state with the most risk. The table below lists the criteria pollutants and current standards. A 

discussion of current air quality conditions follows.

Ozone

Louisiana meets all of the current National Ambient Air Quality Standards except ozone. Only 

five of the State’s 64 parishes exceeded the 1997 ozone standard and these form the Baton Rouge 

non-attainment area; however, ozone concentrations statewide are close enough to the current

standard and the currently proposed standard range to be of concern. Statewide ozone 

concentrations are within 15% of the eight-hour ozone standard and will require close 

monitoring for the foreseeable future.

Fine Particulate Matter 2.5

After ozone, fine particulate matter represents the second greatest air quality health concern for 

Louisiana. At this time concentrations of fine particulate matter currently meet the existing 

standard. 

Particulate Matter 10

Louisiana has met the current PM10 standard for many years and had reduced the number of 

monitors in anticipation of the revocation of the standard. After the standard was retained, the 

number of PM10 monitors in the state was increased to meet the regulatory requirements.

Sulfur Dioxide 

The standard for sulfur dioxide is clearly being met statewide. The sulfur dioxide annual mean 

standard is 30 ppb. The new 75 ppb 1-hour standard may be exceeded in the parishes of East 

Baton Rouge, Ouachita, Calcasieu, and Bossier.

Oxides of Nitrogen

Oxides of nitrogen also clearly meet the standard. While not of direct concern, this pollutant is 

also important for the major role it plays in ozone formation. 

Lead

Lead concerns are directed toward individual point sources of lead emissions. Currently there 

are two facilities in Louisiana that require source-specific monitoring. Exide located in Baton 

Rouge and Arcelor-Mittor which is located in LaPlace. The Exide facility is not operating at this 

time. Modeling results do not predict any violations of the standard at these facilities.

Carbon Monoxide

Carbon monoxide levels have remained consistently below the standard in Louisiana. Currently 

carbon monoxide is only monitored at the NCORE station in Baton Rouge.

CURRENT AMBIENT MONITORING NETWORK

The following table provides a summarized view of the general size of the ambient monitoring 

network in Louisiana by current DEQ Region designation.

Looking at the Louisiana monitoring network from the perspective of current federal monitor 

classifications, the following table represents the monitor breakdown by each of the criteria 

pollutants and for the photochemical pollutants (PAM).

ASSESSMENT PROCESS

The development of this assessment report included fours steps. 

A. The review of current federal regulations, Louisiana Implementation Plan and

Maintenance Plans

B. The review of proposed revisions to current NAAQS. 

C. Determine monitors that are well below their applicable NAAQS or redundant.

Based on the review of air quality conditions across the state, ozone, sulfur dioxide, and fine 

particulate matter are the primary air quality concerns for Louisiana. The focus of the 

monitoring network reflects these concerns now and into the future. Monitoring needs for an 

ozone control strategy go beyond just ozone and include precursors such as hydrocarbons and 

oxides of nitrogen. Particulate pollution solutions must have speciation information on the 

particulate as well as time series data provided from continuous monitors. 

The focus of the redesigned network will be on the pollutants of concern: ozone, the precursors 

of ozone, sulfur dioxide, and fine particulate matter. The final network design must be useful for

air quality management planning and be protective of human health. In the long run, the network 

must be able to accommodate changes in population, emission levels, and resources.

CURRENT AND PROPOSED MONITORING REQUIREMENTS

The first step in the process was to establish what is required of the state in terms of monitoring. 

Monitoring requirements are contained in federal regulations, State Implementation Plans and 

State Maintenance Plans. Of these, federal regulations and the State Implementation Plan for 

Baton Rouge are probably the least flexible and are used to tabulate the list of required monitors

(Table 4). The State Maintenance Plan commitments are flexible and monitoring requirements 

can be modified with EPA regional approval (Table 5). 

The monitoring requirements for the NAAQS pollutants are contained in CFR 40, Parts 53 to 59. 

These regulations describe monitoring objectives and general criteria to be applied in 

establishing State Air Monitoring Stations (SLAMS), Photochemical Assessment Monitoring 

Stations (PAMS), and NCORE Stations. 

SLAMS criteria for number of sites are based on MSA population. The primary objective of the 

SLAMS network is to monitor areas where the pollution concentrations and the population 

exposure are expected to be the highest. These sites are considered by EPA to be long term

monitoring sites to support national air quality assessments and trends. Changes in this network 

are usually difficult to obtain and require EPA Administrator approval. Table 3 includes a 

summary of monitors required by current and proposed regulations. MSA population determines 

the number of monitors required.

In 1993, EPA promulgated requirements for states to establish PAMS in certain ozone nonattainment areas. These monitoring requirements are specifically outlined in the current 

regulations. Two to four PAMS are required for the Baton Rouge area based on the ozone 

nonattainment classification. 

The Baton Rouge State Implementation Plan (SIP) includes monitoring requirements; however, 

these monitoring requirements are not stated in the plan but are implied. 

Maintenance Plans include specific monitoring commitments made by the State. The State may 

elect to change the maintenance plans with concurrence with EPA. These changes must go 

through the administrative procedures process. Because the State has the ability to modify the 

monitoring requirements contained in the Maintenance Plans, these requirements are not 

considered as mandatory. However, some of the monitoring commitments may remain in the 

revised Maintenance Plans because of other requirements, future requirements or if the state feels 

it is prudent to maintain these sites. In short, they were not considered as mandatory in this 

network assessment. 

Special purpose sites are established by the state and are controlled by the state. EPA approval 

for the removal or relocation of monitors is not required.

REDUCTION AND ELIMINATION OF MONITORS 

This portion of the assessment deals with elimination of criteria pollutant monitors. The 

proposed monitoring regulations stress that any SO2, CO, PM10 or NOx monitor which has shown 

attainment during the previous 5 years, that has a probability of less than 10 percent of exceeding 

80 percent of NAAQS during the next 3 years based on the levels, trends and the variability 

observed in the past may be removed from the statewide network. Although this is the case for 

some monitors, the SO2, CO, and PM10 network in Louisiana provides a good overall picture of 

air quality in respect to these pollutants throughout the state and the new SO2 1-hr standard will 

require monitoring for possible control strategies. 

The PM2.5 network in Louisiana is slightly redundant in the Baton Rouge and New Orleans areas, 

but additional PM2.5 monitors in other areas support AQI reporting and forecasting. The 

department is moving toward automation of the PM2.5 network in order to free up manpower

resources for other areas and ultimately reduce the redundant monitors in the Baton Rouge and 

New Orleans area.

The most needed pollutant for reduction and reallocation of monitors is ozone. Many ozone 

monitors in the Baton Rouge MSA were originally sited in order to study transport. Due to the 

wording of the federal regulations these monitors can not be removed although many of them are 

redundant and provide the same information as other nearby monitors. This redundancy was 

statistically proved by network assessment tools provided by EPA.(see appendix) DEQ would 

like to work with the EPA administration towards a reduction of ozone monitors in the Baton 

Rouge MSA from 10 to 7 in order to free up resources toward other monitoring goals. The 

location of the proposed seven sites within this region needs further study. The NOx monitors 

associated with these ozone monitors would also be removed, bringing the number of NOx

monitors in the Baton Rouge MSA to 9. 

SUMMARY

An assessment of the current ambient air quality monitoring network indicates that Louisiana is 

at a pivotal point. Decisions must be made relative to the resources available to the Department 

to operate the extensive air monitoring network. The Baton Rouge area could see a 

reconfiguration of the existing network into seven sites, one of which is an NCore multipollutant monitoring site. 

This proposed monitoring concept was developed using the following guiding objectives 

1. Assess current regulations, state implementation and maintenance plans and eliminate 

monitors that are not required or needed.

2. Continue efforts related to ozone to address potential non-attainment areas, potential PM 

Fine non-attainment areas, and potential sulfur dioxide 1-hr non-attainment areas. These 

issues pose the most pressing environmental health concerns for the State.

3. Eliminate monitors that clearly demonstrate that the standard is met and are not useful for 

other purposes.

This consolidation of the network will provide an advantage in the future. The reduction in the 

number of monitoring sites will facilitate the ability to remotely operate much of the network 

from a central location. The integration and automation of network operations can result in cost 

savings and provide real time data to air managers and the public.
