## INTRODUCTION

T his report provides a n 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 fina ncial 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 Amb ient 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 re gion 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 m inimum 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 cond itions.



## 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 crit eria 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 a ir 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 curr ent air quality conditions follows.

### Ozone

Louisiana meets all of the current National Ambient Air Quality Stan dards except ozone

. Only five of the State’s 64 parishes exceed ed the 1997 ozone standard and th ese form the Baton Rouge

non

- attainment area ; h owever
, ozone concentrations statewide are close enough to the current
standard and the current ly proposed standard range to be of concern. Statewide ozone concentrations are within 15% of the eight

- hour ozon e standard and will require close monitoring for the foreseeable future.

Fine Particulate Matter 2.5

A fter ozone, fine particulate matter represents the second greatest air quality health concern for Louisiana. At this time concentrations of fine partic ulate matter currently meet the existing

standard.

Particulate Matter 10

Louisiana has met the current PM 10 

### standard for many years and had reduced the number of monitors in anticipation of the r evocation of the standard. After the standard was retained, the

number of PM 10 

### 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 an nual 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 me et 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 individua l 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. M odeling 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 Bat on Rouge.



## CURRENT AMBI E NT 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 f ederal monitor

classification s, the following table represents the monitor breakdown by each of the criteria pollutant s and for the photochemical pollutants (PAM).

## ASSESSMENT PROCESS

The development of this assessment report included fours steps.

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

Maintenance Plans

B. The review o f proposed revision s 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 qua lity concerns for Louisiana. The focus of the monitoring network reflects these concerns now and in to the future. Monitoring needs for an

ozone control strategy go beyond just ozone and include precursors such as hydrocarbons and oxides of nitrogen. Par ticulate pollution solutions must have speciation information on the particulate as well as time series data provided from continuous monitors.

The focus of the redesign ed network will be on the pollutants of concern: ozone, the precursors of ozone, s ulfur 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.



## C URRENT AND PROPOSED MONITORING REQUIREMENTS

The first step in the process was to establish what is required of the state in terms of monitor ing. Monitoring requirements are contained in f ederal regulations, State Implementation Plans and

State Maintenance Plans. Of these, f ederal regulations and the State Implementation Plan for Baton Rouge are probably the least flexible and are used to tab ulate 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 C F R 40, Parts 53 to 59. These regulations describe monitoring objectives and general criteria to be applied in establishing State A ir Monitoring Stations (SLAMS), Photochemical Assessment Monitoring Stations (PAMS)

, and N CORE Stations.

SL AMS criteria f

or number of sites are based on MSA population. The primary objective of the

SL AMS 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 regulation s

. MSA population determines

the number of monitor s required.

- In 1993, EPA promulgated requirements for states to establish PAMS in certain ozone non

attainment 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; h owever, these monitoring requirements are not stated in the plan but a re 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 S tate 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

r evised Maintenance Plans because of other req uirements, 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 M ONITORS

This portion of the assessment deals with elimination of criteria pollutant monitors. The proposed monitoring regulations stress that any SO 2 

### , CO, PM 10 

### or NO

x 

### 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 SO 2 

### , CO, and PM 10 

### network in Louisiana provides a good overall picture of air quality in respect to these pollutants throughout the state and the new SO 2

- resources for other area s 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 trans port. 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 prov ided 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 w ithin this region needs further study. The NO

x 

### monitors associated with these ozone monitors would also be removed, bringing the number of NO

x 

### monitors in the Baton Rouge MSA to 9.



## S UMMARY

An assessment of the current ambient air quality monitoring n etwork 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 multi

p ollutant monitoring site.

This proposed monitoring concept was developed using the following guiding objectives

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

monit ors that are not required or needed.

2. Continue efforts related to ozone to address potential non

- attainment area s, potential PM

Fine non

- attainment areas , and potential sulfur dioxide 1

- hr non

- attainment areas . These issues pose the most pressing environme ntal health concerns for the State.

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

.

This c onsolidation of the network will provide an advantage in the future. The reduc tion in the

number of moni toring sites will facilitate the ability t o 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.
