Presentation Outline

• Update on the NAQI Stations Project

• Background

• Problem Statement

• DEA Intervention

• Overview of NAQI Stations

• NAQI Project Implementation

• Consultation Process

• Outcomes

Background• Currently there are over 130 fully automated air quality monitoring stations owned by

various spheres of government across the country.

• Majority of these stations are located in areas with the highest density of people in order to measure human exposure to air pollution.

• The data from these monitoring stations provide valuable information regarding the state of ambient air quality that the citizens of the Republic are exposed to.

• In addition to providing information on the state of air, data from these stations has been used to develop the National Air Quality Indicator (NAQI) for South Africa.

• The NAQI is based on an annual measure of particulates (PM10) and sulphur dioxide (SO2), two of the most prevalent pollutants in the country.

• The NAQI is based on a FUNCTIONAL and OPERATIONAL monitoring network, for the National Ambient Air Quality Monitoring Network (NAAQMN).

Objectives• To ensure that a fixed number of the forty three (43)

air quality monitoring stations identified for the reporting of the NAQI.

• To ensure that all NAQI stations are operating optimally and meeting minimum data requirements.

Problem Statement• The NAQI was based on networks reporting to the South African Air

Quality Information System (SAAQIS), and the number of stations reporting was not fixed.

• The number of monitoring stations reporting to the SAAQIS is continually fluctuating as new stations come online or the existing networks become non-operational and stop reporting to SAAQIS.

• As a result, the NAQI was continually being informed by an EVER-CHANGING TARGET, thereby making its calculation inconsistent over the calculation period.

Problem Statement• Commissioning of ambient air quality monitoring stations has been an

immense investment by all spheres of government (a monitoring station cost between R2 mil to R3 million depending on the number of instruments installed at the station).

• What has emerged over the years is that many provinces and municipalities have been unable to manage and maintain their monitoring stations at the required level in order to produce credible air quality data, primarily due to the following:

– No budgetary provisions for maintenance and overall operation;– Lack of skills and capacity;– Lack of proper planning for management of stations;– No provision for instrument recapitalization.

DEA Intervention• In light of the current challenges with most of these stations, DEA took a resolution to

assist some of the Provinces and Municipalities by outsourcing the overall management of the stations with a view to have a consistent reporting of NAQI going forward.

• A FIXED number of stations measuring PM10, PM2.5 and SO2 from 2015 have been identified for the reporting of the NAQI.

• Forty-three (43) stations have been selected for the NAQI reporting.

• These NAQI stations represent the spectrum of the National Ambient Air Quality Monitoring Network (NAAQMN) stations characterised by:

– Industrial

– Urban

– Residential

– Traffic

– Background ambient conditions across the country
