2 Presentation Outline Background to Ambient Monitoring in South Africa What QMSs exists? What are the challenges with these systems? What are the objectives of NAAQMN QMS? What is the scope of the NAAQMN QMS? NAAQMN Continuous Monitoring Low costs Monitoring How are we going to roll-out the NAAQMN QMS? What is the way forward?

3 Abbreviations NAAQMN National Ambient Air Quality Monitoring Network SAAQIS South African Air Quality Information System QMS(s) Quality Management System (s) NAAQS National Ambient Air Quality Standards

4 Continuous Ambient Monitoring NAAQMN consists of over 120 monitoring stations About 65 stations are reporting to SAAQIS

5 SAAQIS Website: Public Access to Information

6 SAAQIS APP Available on Android and on IOS LIVE INDEX, POLLUTANTS, METEOROLOGY Ability to plot historical data Generate reports Set APP for personal use with specific stations of interest, settings

7 National Ambient Monitoring Tools NEMAQA, NAAQS, Norm & Standards SANAS Quality Management System NAAQMN NMISA SAAQIS

8 Current QMS in NAAQMN QMS for accreditation SAWS network priority area stations informed by the current SANAS Technical requirements Networks managed by authorities locally developed systems Some QMS are held by service providers when they operate government stations

9 Challenges with current NAAQMN QMSs Systems are limited in completeness or they don t exist at all limited capacity in government QMSs are developed independently by network owners cost to government Where QMSs exist, there is no guidance and consistency in the way the systems have been developed or implemented In most stations, the QMSs are in hard copies, and there are risks in the storage and archiving of documentation QMSs are held by service providers, and as soon as the contract lapse, the systems are lost and a new service provider has to develop systems afresh Stranded stations lose the QMS and new initiates have to be put in place during resuscitation of stations Hence DEA-SAWS intervention to develop a national QMS to support NAAQMN

10 What is the scope of the NAAQMN QMS?

11 Project Objective To develop a NAAQMN QMS with detailed procedures and protocols for the effective management of government owned ambient air quality monitoring stations in line with ISO 17025:2017 test/calibration requirements and ISO 9001 quality requirements NAAQMN QMS will be built as part of the SAAQIS system in order to enable all stations reporting to SAAQIS to implement sound quality systems and demonstrate that network operators are technically competent and able to produce valid and reliable ambient monitoring and calibration protocols Service provider appointed by SAWS

12 NAAQMN Quality System Objectives QMS will support Continuous Ambient Monitoring as well as Low Cost Monitoring in order to: Provide national consistency in the way ambient air quality monitoring is conducted and reported across the NAAQMN Reduce overall government costs in developing parallel quality systems per network/district or provincial level. Provide a framework to assist network owners to implement information technologies and incorporates the use of computer systems, electronic records supported by the new SAAQIS NAAQMN modules

13 National Ambient Monitoring Tools NEMAQA, NAAQS, Norm & Standards SANAS Quality Management System NAAQMN NMISA SAAQIS

14 QMS Project Plan (Continuous Monitoring) Review NAAQMN Systems in SAAQIS Identify QMS gaps in the SAAQIS modules Fill in the gaps and present a complete QMS Pilot QMS with 3 networks Develop national roll-out program of QMS Update the QMS with inputs from piloting phase Assess piloting of QMS

Output B1: Development of procedures, protocols, templates, forms and checklists identified in Output A. Scope of the QMS Verifiable Indicator Assessment of the NAAQMN components; NAAQMN Asset Maintain NAAQMN Data Manager NAAQMN Station Manager Development of procedures, protocols, templates, forms to ensure that three NAAQMN components are aligned to standard requirements. Means of Verification A detailed Assessment Report with recommendations on the gaps between the NAAQMN components and Norms and Standards, against ISO 9001 and ISO 17025:2017 requirements. The report should identify gaps in procedures, protocols, templates, forms, checklists etc. Procedures, protocols, templates, forms identified in Output A developed and presented to DEA/SAWS for implementation into SAAQIS/NAAQMN computer systems.

16 Scope of the QMS: Output B1 Technical Requirements Maintain laboratory environmental condition Handling, transport, storage, use and planned maintenance of equipment Intermediate checks Measurement traceability and calibration Evaluation of measurement uncertainty and statistical techniques for analysis of data Assuring and monitoring of validity of result Transportation, receipt, handling, protection, storage, retention, and disposal or return of test items Control of data Document and data control Control of records Method validation Management Requirements Personnel and training Management review Corrective action Internal audit Procurement of externally provided products and services Review of requests, tenders and contracts Receiving, evaluating and making decisions on complaints Control of non conforming work Risk assessment

17 Outcomes from Output B1 Technical Manual Outcomes Procedures for the handling of transportation, storage, usage and maintenance of measuring equipment Procedures for the performance of intermediate check on the equipment Justifiable calibration programs Equipment instructions that is readily available Records for the laboratory equipment including historical performance so that trends can be identified Measurement traceability of equipment calibration Management Manual Outcomes Ensure consistency of practices, activities, processes and systems; Clear transmission of information resulting from a minimal loss of information; Permanent, written and dependable information results in improved understanding, by: Providing basic control; Eliminating uncertainty and confusion; Providing direction; Improved control and the management of changes prevents shortcuts ; and

20 What is the scope of the NAAQMN QMS? Low Cost Sensors

21 MUST MAY NOT ADVISABLE Monitoring Requirements Categories Level 1 - Core monitoring of ALL pollutants using reference methods Level 2 Requirements to install continuous monitoring MUST be informed by screening Monitoring MUST include PM and SO 2 and O 3 Other specific pollutants can be considered No requirement to monitor all pollutants Level 3 Regularly conducting screening monitoring in order to assess AQ status In case of deteriorating AQ levels, Level 2 monitoring MUST be considered NAQI Stations providing the National AQ Indicator across all levels
