uMoya-Nilu is a South African air quality management consulting company with expertise and experience to address Air Quality Management challenges facing a range of stakeholders in southern Africa.
With strong ethics and values, uMoya-NILU's mission is to provide clients with Air Quality Management Solutions that are well researched, appropriate, and sustainable. The experience of the uMoya-NILU personnel has been developed through their involvement in operational air quality management and in consulting and research projects over a collective period of more than 40 years.
uMoya-NILU is truly a South African company with bona fide Broad Based BEE credentials, with non-white South African directors on the board who hold 51% of the company´s shares and a Level 2 BEE rating.
uMoya-NILU's diverse and experienced team offers services in many fields relating to air quality management and planning. For more information, please refer to our services listed to the right.
uMoya-NILU offers services in the development and review of Air Quality Management Plans (AQMPs) for different spatial scales, i.e. provinces, metro, district and local municipalities.
uMoya-NILU provides specialist air quality studies as input to Environmental Impact Assessments, Atmospheric Impact Reports (AIR) and Atmospheric Emission License (AEL) applications. Included are baseline air quality assessments, specialist air quality studies, dispersion modelling, emission inventory compilation and assessment and mitigation planning.
Air quality baseline and impact assessments for industrial development projects and for AQMPs require input in a number of specialised areas. While dispersion modelling is often the primary assessment approach, it is supported by ambient air quality and meteorological monitoring and emission determination.
The range of skills required are resident at uMoya-NILU, providing a single-consultancy specialist team. The team has developed considerable experience through numerous impact assessment projects of different scales for industry and mining throughout southern Africa, including Namibia, Mozambique, Zambia and of course, South Africa.
uMoya-NILU’s service offering in Ambient Monitoring includes the design, optimisation and management of Ambient Air Quality monitoring networks, as well as Data Management and Quality Control / Quality Assurance.
uMoya-NILU offers monitoring services that include real time gas and particulate analysers, dust fall out buckets and passive samplers for campaign or long term monitoring purposes. Sampling can be performed for a range of organic and inorganic pollutants.
Through our partnership with NILU, uMoya-NILU utilises their extensive analytical capabilities which are recognised throughout the EU to offer our clients direct access to a quality assured and quality controlled analytical service.
The analytical capabilities extend to an extensive range of inorganic and organic analytes, low detection levels, coupled with rapid turn around times.
uMoya-NILU has also set up an in-house gravimetric laboratory and a SANAS ISO:17025 accredited calibration laboratory.
An emission inventory is a listing, by source, of the amounts of pollutants actually or potentially discharged. Such an inventory is used to establish and put forth emission standards.
uMoya-NILU led the development of the National Atmospheric Emission Inventory System (NAEIS) for the Department of Environmental Affairs. uMoya-NILU has extensive process engineering experience in the petro-chemical and manufacturing industry and in the establishment of urban-scale emissions inventories.
Subcategories 2.4, 2.5 and 3.3, and Category 6 Listed Activities are required to institute leak detection and repair (LDAR) programmes in accordance with USEPA Method 21.
LDAR programmes are intended to identify leaking equipment through the measurement of VOC concentrations and the subsequent repair of the leaks in order to reduce fugitive emissions.
uMoya-NILU has the capability and experience to undertake LDAR programmes. Our methodologies and equipment have been approved by the licensing authorities of various provinces and municipalities.
We use a flame ionization detector (FID) to measure the concentration of VOC species in a gas stream to ppm levels. The output of our programme is a list of leaking equipment such as valves, flanges and pump seals, which we issue to our clients for further repair.
A stack test is a procedure for sampling a gas stream from a single sampling location at a facility, unit, or pollution control equipment. It is used to determine a pollutant emission rate, concentration, or parameter while the facility, unit, or pollution control equipment is operating at conditions that result in the measurement of the highest emission or parameter values. Listed activities must comply with emission limits as specified in their Atmospheric Emission Licences.
Listed Activities are also required to measure emissions at least once per year and report these to the NAEIS.
uMoya-NILU offers the service of emission testing to determine compliance with these emission limits, in accordance with the USEPA and ISO methods specified in Listed Activities regulation.
Our emission testing team comprises four technicians with a collective experience of more than 20 years. Our current clients in emission testing include major players in the oil and gas, manufacturing and mining industries.
uMoya-NILU’s experience in the regulatory environment, in industrial and chemical engineering, and their understanding of the requirements Atmospheric Emission Licensing and the Section 21 regulation places them in a strong position to assist companies with AEL applications, renewals and variations.
The development and implementation of the South African Emission and Licensing Portal (SAAELIP) has moved the application to an on-line process. uMoya-NILU has developed extensive experience with the requirements of the SAAELIP.
uMoya-NILU led the development of the National Atmospheric Emission Inventory System (NAEIS) for the Department of Environmental Affairs. Listed Activities, mining and controlled emitters are required to report emissions annually to the NAEIS. uMoya-NILU has developed extensive experience with the requirements of NAEIS reporting and assists a number of organisations annually.
uMoya-NILU collaborates with the National Association of Clean Air (NACA) in offering training courses in Air Quality Management as well as the associated specialist disciplines of Ambient Air Quality Monitoring, Emissions Inventories and Dispersion Modelling.
