Environmental Compliance Monitoring
Noise, Dust, Stack & Air Quality Assessment & Modelling
Service: Ambient & Indoor Air Quality (IAQ) Monitoring
Location: Chonburi, Eastern THAILANDClient: Global Heavy Lifting Gear Manufacturer
Project Value: Confidential
SLP Environmental was commissioned by a European Client to provide stack, ambient air, internal and external noise and internal dust compliance monitoring services at a Steel Foundry and Machine Shop Facility located in Chonburi on the eastern seaboard of Thailand.
10No. positions were selected for nuisance noise monitoring using RION Integrated Sound Level Meters, 6No. positions were selected for dust monitoring using cyclone pumps with 37mm filters with Gravimetric measurement as per NIOSH 0600 and 1No. ambient air monitoring station was positioned at a fence line between the main furnace stack and the nearest neighbouring residential properties for a 24 hours period. The four atmospheric vent stacks present on site were associated with the Sand Treatment System (with Dust Cyclone pollution abatement technology) and Furnace Flue Gas (with Wet Scrubber pollution abatement technology).
Additional sampling ports were installed to ensure compliance with the relevant Notification of the National Environmental Board B.E. 2549 methodologies. As no sampling gantry was constructed a platform lift was hired to undertake the stack sampling works which were undertaken using Chemical Absorption and Isokinetic Methods.
Following the completion of the compliance monitoring a Compliance Monitoring Report was produced detailing the monitoring results, findings, conclusions and recommendations for further works and an on-going monitoring strategy.
Service: Development of a Regional Air Quality Strategy
Location: Southern England, UK
Client: UK Regional Authority
Project Value: Confidential SLP Affiliates were involved in a long term partnership to manage air quality across an entire English County. The primary objective of the exercise was to formulate an effective air quality improvement strategy implemented via local Action Plans for the jurisdiction which did not merely compromise air quality in neighbouring counties.
The scope of works undertaken to deliver the objective included comprehensive real time monitoring and specialised computer modelling to assess the impacts of various transport scenarios. Yearly auditing of the formulated Action Plans was also undertaken to allow refinement and modification as necessary.
The detailed work includes:
1) The installation of additional precision air quality monitoring devices for both model verification, development of new tools, and compliance monitoring.
2) The development of regional multi-source emissions inventories for the current and several future years
3) Building of a detailed dispersion air quality model for the region.
4) Complex base year model, including verification in urban areas, rural areas, street canyons, bus stations.
5) Assessment of 2010 to determine whether any locations will exceed 2010 EU limit values.
6) Development of action plans to address exceedance areas by practical and achievable means.
7) Year on year re-modelling until 2010 to audit progress of actions plans and allow synergistic response to proposed schemes and developments affecting land use and transport systems.
8) Longer term move to semi-automation of AQ control systems.
Key project outputs included the development of extended traffic models specific to air quality modelling needs and a large and detailed air quality model for traffic and industrial sources. This was supported by a GIS display of all key indicators including a pollutant emissions inventory and a carbon emissions inventory. The ultimate deliverable was a detailed Action Plan focused at the local level that could be subject to review and refinement in the period leading up to 2010.
